Step-by-step explanation:

when we Roll a fair 6 66-sided die. then the probability of P (not 5) is 65/66

     The concept used a die is a tool used for games and gambling. The die is a cube with six faces, each of which has a different number of dots from one to six. The roll of a die is a random event, which means that it is unpredictable, and each roll is independent of any other roll.

 Let's solve the question that is P(not 5)

                 Since the die is fair, we have 66 sides on the die. Each of the sides has a probability of 1/66 of being rolled. P(not 5) means that we need to determine the probability of rolling a number that is not 5.

           We know that a 66-sided die has 65 numbers other than 5.

     Therefore, the probability of rolling a number that is not 5 is 65/66.

            P(not 5) = 65/66

   So, the probability of not rolling a 5 is p(not 5) = 65/66.

The measure of side E'F' of rectangle EFGH when dilated by a scale factor of 3 to form rectangle E'F'G'H' is 66 units.

Scale factor is used in mathematics, particularly in geometry and measurement, to describe the transformation of one figure into another through dilation or resizing. It is represented by a number or a ratio, such as 2:1 or 1/2, which indicates how many times larger or smaller the new figure is compared to the original. For example, if the side length of a square is doubled, the resulting square is four times larger in area, because the area of a square is proportional to the square of its side length. In this case, the scale factor of the dilation is 2, because the new square is twice as large as the original square. Scale factor is also used in maps, blueprints, and architectural drawings to represent the ratio between the actual size of an object or space and its representation on paper or screen.

Here,

If rectangle EFGH is dilated by a scale factor of 3 to form rectangle E'F'G'H', then all corresponding sides of the two rectangles are in the ratio of 3:1. Since EF measures 22, then the corresponding side E'F' of the dilated rectangle is:

E'F' = EF × scale factor

E'F' = 22 × 3

E'F' = 66 units

Therefore, the measure of side E'F' is 66.

On the material was used, the 100-meter flex of 14 AWA wire's entirety would range. If the silver and copper cable are in 0.0013 and 0.0014, aluminum spans 0.002 and 0.004, and iron is between 0.007 and 0.008

A force that works to slow something down or halt its progress: The air/wind drag slowed the vehicle down. the extent to which a material obstructs an electric charge from passing through it: There is little reluctance in copper.

The resistance (R) of a wire is given by the formula:

R = (ρ x L) / A

where:

ρ is the resistivity of the material

L is the length of the wire

A is the wire's cross-sectional size.

The cross-sectional area (A) of a wire with diameter d is given by the formula:

A = π x (d/2)²

where pi is a number in mathematics. (approximately equal to 3.14).

For a 100-meter length of 14 AWA wire with diameter 0.163 cm, we first need to convert the diameter to meters:

d = 0.163 cm = 0.00163 m

The cross-sectional area of the wire is then:

A = π x (0.00163/2)² = 2.087 x 10⁻⁶ m²

Using this value of A and the given resistivities, we can calculate the resistance for each material:

For copper:

R_copper = (1.67 x 10⁻⁸ O•m x 100 m) / (2.087 x 10⁻⁶ m²) = 0.00134 Ω

For silver:

R_silver = (1.59 x 10⁻⁸ O•m x 100 m) / (2.087 x 10⁻⁶ m²) = 0.00128 Ω

For aluminum:

R_aluminum = (2.65 x 10⁻⁸ O•m x 100 m) / (2.087 x 10⁶ m²) = 0.00199 Ω

For iron:

R_iron = (9.71 x 10⁻⁸ O•m x 100 m) / (2.087 x 10⁻⁶ m²) = 0.00735 Ω

Therefore, the overall resistance of the 100-meter length of 14 AWA wire made of these materials would depend on which material was used. If copper or silver were used, the resistance would be relatively low, around 0.0013-0.0014 Ω. If aluminum were used, the resistance would be higher, around 0.002 Ω. If iron were used, the resistance would be much higher, around 0.007 Ω.

The logarithmic number is associated with exponent and power, such that if xⁿ = m, then it is equal to logₓ m = n. That is exponential value are inverse of logarithm values. Some basic properties of logarithmic numbers:

Now, we solve each logarithm equation one by one. Assume that 'log' is the base-10 logarithm where absence of base.

1) log (5x) = log (2x + 9)

Exponentiate both sides

=> 5x = 2x + 9

=> 3x = 9

=> x = 9

2) log (10 − 4x) = log (10 − 3x)

Exponentiate both sides,

=> 10 - 4x = 10 - 3x

simplify, => x = 0

3) log (4p − 2) = log (−5p + 5)

Exponentiate both sides,

=> 4p - 2 = - 5p + 5

simplify, => 9p = 7

=> p = 7/9

4) log (4k − 5) = log (2k − 1)

Exponentiate both sides,

=> 4k - 5 = 2k - 1

simplify, => 2k = 4

=> k = 2

5) log (−2a + 9) = log (7 − 4a)

Exponentiate both sides,

=> - 2a + 9 = 7 - 4a

simplify, => 2a = -2

=> a = -1

6) 2log₇( −2r) = 0

=> log₇( −2r) = 0

using the property, log꜀a = n <=> cⁿ = a

=> ( 7⁰) = - 2r

=> -2 × r = 1 ( since a⁰ = 1 )

=> r = -1/2

7) −10 + log₃(n + 3) = −10

=> log₃(n + 3) = −10 + 10 = 0

using the property, log꜀a = n <=> cⁿ = a

=> 3⁰ = n + 3

=> 1 = n + 3

=> n = 2

8) −2log₅ ( 7x ) = 2

=> log₅ 7x = -1

=> 5⁻¹ = 7x

=> x = 1/35

9) log( −m) + 2 = 4

=> log( −m) = 2

Exponentiate both sides,

=> -m = 2

=> m = -2

10) −6log₃ (x − 3) = −24

simplify, log₃ (x − 3) = 4

=> (x - 3) = 3⁴ ( since log꜀a = n <=> cⁿ = a )

=> x - 3 = 81

=> x = 84

11) log₁₂ (v²+ 35) = log₁₂ (−12v − 1)

=> log₁₂ (v²+ 35) - log₁₂ (−12v − 1) = 0

Using the quotient property of logarithm,

[tex]log_{12}( \frac{v²+ 35}{-12v-1}) = 0 [/tex]

[tex]\frac{v²+ 35}{-12v - 1} = {12}^{0} = 1 [/tex]

[tex]v²+ 35 = −12v − 1[/tex]

[tex]v²+ 35 + 12v + 1 = 0[/tex]

[tex]v²+12v + 36 = 0[/tex]

which is a quadratic equation, and solve it by middle term splitting method,

[tex]v²+ 6v + 6v + 36= 0[/tex]

[tex]v(v + 6) + 6(v + 6)= 0[/tex]

[tex](v + 6) (6 + v)= 0[/tex]

so, v = -6, -6

12) log₉(−11x + 2) = log₉ (x²+ 30)

=> log₉ (x²+ 30) - log₉(−11x + 2) = 0

Using the quotient property of logarithm,

[tex]log₉(\frac{x²+ 30 }{−11x + 2}) = 0[/tex]

[tex] \frac{x²+ 30}{-11x + 2} ={9}^{0} = 1 [/tex]

=> x² + 30 = - 11x + 2

=> x² + 11x + 30 -2 = 0

=> x² + 11x + 28 = 0

Factorize using middle term splitting,

=> x² + 7x + 4x + 28 = 0

=> x( x + 7) + 4( x + 7) = 0

=> ( x + 4) (x+7) = 0

=> either x = -4 or x = -7

Answer:

[tex]\textsf{$\boxed{\checkmark}\;\;y$-value\;of\;vertex\;is\;$-1$}[/tex]

[tex]\textsf{$\boxed{\checkmark}$\;\;Minimum\;value\;occurs\;at\;$y = -1$}[/tex]

Step-by-step explanation:

Given equation:

[tex]y=x^2+8x+15[/tex]

As the given equation is quadratic with a positive leading coefficient, it is a parabola that opens upwards. Therefore, its vertex is its minimum point. This means that the minimum value of the range is the y-value of the vertex.

The x-value of the vertex of a parabola in the form y = ax² + bx + c is x = -b/2a. Therefore, the x-value of the vertex of the given equation is:

[tex]\implies x=\dfrac{-8}{2(1)}=-4[/tex]

To find the y-value of the vertex, substitute x = -4 into the equation:

[tex]\begin{aligned}\implies y&=(-4)^2+8(-4)+15\\&=16-32+15\\&=-16+15\\&=-1\end{aligned}[/tex]

Therefore, the minimum y-value of the function is y = -1, so the range is y ≥ -1.

Therefore, the following are true statement about the given equation:

The half-life of an isotope is the time by which there is a 50% probability that decay has occurred if Cobalt-60 has a half-life of 5.27 years then mean time to decay is 7.65 years , standard deviation of the decay time is 3.82 years , the 99th percentile is  36.4 years and  the mean and standard deviation of the total time the experiment will last is 6.61 years.

(a) The mean time to decay can be found using the formula: [tex]mean = half-life / ln(2)[/tex].

Therefore, for cobalt-60 with a half-life of 5.27 years, the mean time to decay is:

[tex]mean = 5.27 / ln(2) \approx7.65 years[/tex]

(b) The standard deviation of the decay time can be found using the formula:

standard deviation =    [tex]half-life /(\ sqrt{(ln(2))}).[/tex]

Therefore, for cobalt-60 with a half-life of 5.27 years, the standard deviation of the decay time is:

standard deviation = [tex]5.27 / (\sqrt{(ln(2))}) \approx 3.82 years[/tex]

(c) The 99th percentile can be found using the cumulative distribution function (CDF) of the exponential distribution. For cobalt-60 with a half-life of 5.27 years, the CDF is:

[tex]CDF(t) = 1 - e^{(-t/5.27)}[/tex]

Setting the CDF equal to 0.99 and solving for t, we get:

[tex]0.99 = 1 - e^{(-t/5.27)}[/tex]

[tex]e^{(-t/5.27)} = 0.01[/tex]

[tex]-t/5.27 = ln(0.01)[/tex]

[tex]t = -5.27 * ln(0.01)[/tex]

[tex]t\approx 36.4 years[/tex]

Therefore, the 99th percentile of the decay time for cobalt-60 is approximately 36.4 years.

(d) Three cobalt-60 atoms, then the total time the experiment will last is the sum of the decay times of each atom. Since the decay times are independent and identically distributed, the mean and standard deviation of the total time can be calculated by adding the means and variances of each individual decay time.

The mean of the total time is:

[tex]mean(total) = mean(atom1) + mean(atom2) + mean(atom3)[/tex]

[tex]mean(total) = 7.65 + 7.65 + 7.65[/tex]

[tex]mean(total) = 22.95 years[/tex]

The variance of the total time is:

[tex]variance(total) = variance(atom1) + variance(atom2) + variance(atom3)[/tex]

[tex]variance(total) = (3.82)^2 + (3.82)^2+ (3.82)^2[/tex]

[tex]variance(total) \approx43.67 years[/tex]

The standard deviation of the total time is the square root of the variance:

standard deviation(total) [tex]= \sqrt{(variance(total))}[/tex]

[tex]standard deviation(total) \approx6.61 years[/tex]

Answer: 1.1. The donation per learner cannot be determined from the given table.

1.2. TABLE 1: INCOME IN RANDS OF FUNDRAISING

Number of learners that paid Income (R)

1 200

1.3. To calculate the missing value A, we need to add up all the given incomes and subtract it from the total income for 45 learners, which is 45 x A. Then we can solve for A:

Total income = 200 + 150 + 10(2,000) + 20(45) + A + 4,000 + 9,000

Total income = 45A

45A = 25,150

A = 558.89

Therefore, the missing value A is R558.89.

1.4. The dependent variable in the table is the income received from fundraising.

To find the ratio of income received from 10 learners to income received from 45 learners, we need to divide the income received from 10 learners by the income received from 45 learners and simplify the fraction:

Income from 10 learners = R1,100 (since each learner donates R110)

Income from 45 learners = R215

Ratio = Income from 10 learners : Income from 45 learners

= 1,100 : 215

= 20 : 3 (in its simplest form)

The total number of learners enrolled at the school is 1,100. If 80% of the learners paid, then the number of learners who paid is:

80% of 1,100 = 0.8 x 1,100 = 880 learners

The minimum income that the school can raise if 80% of the learners paid is when each of the 880 learners paid the minimum donation, which is R150:

Minimum income = 880 x 150 = R132,000

The answer is (c) [tex]13.2 \pm 33.1[/tex], which is not correct.

Which is the confidence interval?

A confidence interval is a range around a measurement that conveys how precise the measurement is.

We can use the two-sample t-interval formula to find the confidence interval for the difference in means:

[tex]$\bar{x}_W - \bar{x}M \pm t{\alpha/2, \nu} \sqrt{\frac{s_W^2}{n_W} + \frac{s_M^2}{n_M}}$[/tex]

where [tex]$\bar{x}_{W}$[/tex] and [tex]$\bar{x}M$[/tex] are the sample means, [tex]$s_W$[/tex] and [tex]$s_M$[/tex] are the sample standard deviations, [tex]$n_W$[/tex] and [tex]$n_M$[/tex] are the sample sizes, [tex]$\nu$[/tex] is the degrees of freedom, and [tex]$t{\alpha/2, \nu}$[/tex] is the critical value from the t-distribution with [tex]$\nu$[/tex]degrees of freedom and a level of significance of [tex]$\alpha=0.1$[/tex] (since we want a 90% confidence interval, which corresponds to a 10% level of significance).

Plugging in the values, we get:

[tex]$\bar{x}_W - \bar{x}M \pm t{0.05/2, 23} \sqrt{\frac{s_W^2}{n_W} + \frac{s_M^2}{n_M}}$[/tex]

[tex]$\begin{aligned} &= 213.6 - 226.8 \pm t_{0.025, 23} \sqrt{\frac{45.3^2}{14} + \frac{49.4^2}{11}} \ &= -13.2 \pm 2.074 \times 13.102 \ &= -13.2 \pm 27.115 \end{aligned}$[/tex]

Therefore, the 90% confidence interval for [tex]$\mu_W - \mu_M$[/tex] is approximately [tex]$-13.2 \pm 27.1$[/tex], or (-40.3, 13.9).

The solution of the system goes to infinity as t gets large.

Consider the given system of differential equations: dx/dt = 3x + 4ydy/dt = −x − 2yNow, find the solution of the system:(2)   dx/dt + 2 dy/dt = 7xObserve the second equation and multiply it by 2:2  dy / dt = −2x − 4y(3)   dx/dt + 2 dy/dt = 3x − 4ySubstitute the value of dy/dt from (3) into (2):(2)   dx/dt + 3x − 4y = 7xSimplify this equation:dx/dt − 4x = 4yTake the laplace transform of both sides: Laplace{dx/dt − 4x} = Laplace{4y} ⇒ sX(s) − x(0) − 4X(s) = 4Y(s) ⇒ X(s) = {4Y(s)}/{s − 4}Now, find the Laplace transform of y(s):(1)   dy/dt = −x − 2y ⇒ Laplace{dy/dt} = −Laplace{x} − 2Laplace{y} ⇒ sY(s) − y(0) = −X(s) − 2Y(s) ⇒ Y(s) = {−X(s)}/{s + 2}Substitute the value of X(s) in the above equation, we get:Y(s) = {−4Y(s)}/[(s − 4)(s + 2)]Simplify this equation:Y(s) = {A}/{s − 4} + {B}/{s + 2}Now, find the values of A and B:Multiplying the above equation by (s − 4) and (s + 2), we get:Y(s) = A(s + 2) + B(s − 4)Simplify this equation:Y(s) = (A + B)s + 2A − 4BAs per the equation (3), we can say A + B = 0, 2A − 4B = −4On solving, we get A = 2, B = −2Therefore, the value of Y(s) is:Y(s) = {2}/{s − 4} − {2}/{s + 2}Now, substitute the value of X(s) and Y(s) in the following equation:dx/dt − 4x = 4yThe solution of the above differential equation is:x(t) = {2}/{3}e^{4t} − {5}/{3}e^{-2t}The above is the general solution of the given system of differential equations.Now, find what happens to the system as t gets large?As t gets large, the term {5}/{3}e^{-2t} will tend to zero and {2}/{3}e^{4t} will tend to infinity.

The probability that the second child born to the couple will have blood type AB is 1/2.

Blood grouping is the categorization of blood into groups depending on the type of antigen and antibody present on the surface of red blood cells (RBCs).

The ABO blood grouping system, which includes A, B, AB, and O blood types, is the most well-known blood grouping system.

Blood group Rh (Rhesus) grouping system is another well-known blood grouping system that can be determined.

Therefore, the probability that the second child born to the couple will have blood type AB is 1/2.

50 percent of the offspring of this couple will inherit the gene for the ABO blood type A from the mother, while the remaining 50% will inherit the gene for the blood type B from the father.

The probability of inheriting the gene for blood type AB is thus 1/2 for a child born to these parents.

Answer:

The correct options are A and B.

For option A:

Sy = y = 3x - 10

Substituting x = -8 and y = 4:

4 = 3(-8) - 10

4 = -24 - 10

4 = -34

Since the left-hand side does not equal the right-hand side, (-8,4) is not a solution to the system.

For option B:

y = -1x + 10

Substituting x = -8 and y = 4:

4 = -1(-8) + 10

4 = 8 + 10

4 = 18 - Incorrect

For option C:

y = 5x + 24

y = 5(-8) + 24

y = -40 + 24

y = -16 - Incorrect

For option D:

y = 6x + 68

Substituting x = -8 and y = 4:

4 = 6(-8) + 68

4 = -48 + 68

4 = 20 - Incorrect

For option E:

y = -3x + 7

9 = -3(-8) + 7

9 = 24 + 7

9 = 31 - Incorrect

Therefore, options A and B are incorrect.

The value of m∠JKL is 34°

An angle formed by a tangent and a secant intersecting outside a circle is equal to one-half the difference of the measures of the intercepted arcs.

Based on the theorem above, we can say:

m∠JKL = 1/2 * (159 - 91)

m∠JKL = 1/2 * 68

m∠JKL = 34°

Therefore, the value of m∠JKL in the circle is 34°.
