Answer:

1743.46[tex]\frac{meters}{min}[/tex]

Step-by-step explanation:

Two unit multipliers will be used here:

1 mile (mi)  = 1,609.344 meters

1 hour (hr) = 60 minutes (min)

65 [tex]\frac{mi}{hr}[/tex] = (65[tex]\frac{mil}{hr}[/tex])×([tex]\frac{1609.344 meters}{1 mile}[/tex])×([tex]\frac{1 hour}{60 minutes}[/tex])

The miles unit in the numerator and denominator will cannel each other out completely. In addition, the hour unit in the numerator and denominator will also cancel each other out completely:

         = 1743.46 [tex]\frac{meters}{min}[/tex]

Using the values provided on the sketch of the triangular trellis, the values for x, y, and z are 13.33 ft, 6.75 ft, and 17.37 ft, respectively.

From the provided sketch of the trellis, we can use the similar triangles and similar trapezoids to solve the values of x, y, and z.

Consider similar trapezoids at the bottom of the trellis.

10/(10 + 6) = x/(8 + x)

80 + 10x = 16x

6x = 80

x = 40/3 = 13.33

Consider the similar triangles at the top of the trellis.

9/(9 + x) = 7/z

9/(9 + 40/3) = 7/z

z = 469/27 = 17.37

y/(y + 10) = 9/(9 + x)

y/(y + 10) = 9/(9 + 40/3)

(67/3)y = 9y + 90

(40/3)y = 90

y = 27/4 = 6.75

Hence, the length of x, y, and z is 13.33 ft, 6.75 ft, and 17.37 ft, respectively.

Answer:

Step-by-step explanation:

The probability of selecting a junior who usually drinks bottled water is 0.0156. This is calculated by finding the probability of each separate event (being a junior and drinking bottled water) and multiplying them together.

To find the probability of selecting a junior who usually drinks bottled water, first calculate the probability of being a junior. There are 12 juniors out of a total of 30 students, so the probability of being a junior is 0.4. Then, calculate the probability of usually drinking bottled water. There are 10 students who usually drink bottled water out of a total of 30, so the probability of usually drinking bottled water is 0.3333. Finally, multiply the probabilities together to get the overall probability of 0.0156. This can be rounded to four decimal places to get the final answer of 0.0156.

Step-by-step explanation:

You want the product of (3a +5) and (2a² +4a -2).

The distributive property is used to eliminate the parentheses when simplifying the product.

  (3a +5)(2a² +4a -2) = 3a(2a² +4a -2) +5(2a² +4a -2)

  = 6a³ +12a² -6a +10a² +20a -10

  = 6a³ +(12+10)a² +(-6+20)a -10

  = 6a³ +22a² +14a -10

Additional comment

The leading coefficient of the product is the product of the leading coefficients: 3·2 = 6. This eliminates the last two answer choices.

The first two answer choices differ only in the "a" term, so you only need to find that one. It will be the sum of terms (3a)(-2) and (5)(4a), so is -6a+20a = 14a.

You can also "guess" that the "a" term will be 14a, because that appears the most often among the answer choices.

The first answer choice is the correct one.

Answer: We can find the value of x by solving the equation 2x + 1/3x = 4.

Combining the terms on the left side, we get:

(6/3)x = 4

Dividing both sides by 6/3, we get:

x = 2

Substituting the value of x back into the expression 27x³ + 1/8x³, we get:

27 * 2³ + 1/8 * 2³ = 27 * 8 + 1/8 * 8 = 216 + 1 = 217

So the value of the expression 27x³ + 1/8x³ is 217.

Correct expression is,

Table A represents an additive relationship because y is 5.5 more than x.

Table B represents a multiplicative relationship because , y, is 4.5 times x.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

These tables represent the relationships between x and y for two different sets of data.

Hence, The equation for table A is,

Two points from the table A are, (1, 6.5) and (2, 7.5)..

Thus, The equation fop table is,

y - 6.5 = (7.5 - 6.5) / (2 - 1) (x - 1)

y - 6.5 = 1 (x - 1)

y - 6.5 = x - 1

y = x - 1 + 6.5

y = x + 5.5

Thus, Table A represents an additive relationship because y is 5.5 more than x.

Hence, The equation for table B is,

Two points from the table A are, (1, 4.5) and (2, 9)..

Thus, The equation fop table is,

y - 4.5 = (9 - 4.5) / (2 - 1) (x - 1)

y - 4.5 = 4.5 (x - 1)

y - 4.5 = 4.5x - 4.5

y = 4.5x

Thus, Table B represents a multiplicative relationship because , y, is 4.5 times , x,.

The required angle is 35 degrees whose supplementary angle is 35 degrees more than twice its complementary angle.

The definition of a supplementary angle is that it adds up to 180 degrees.

Let's represent the required angle as "x".

We know that the supplementary angle to "x" is 180 - "x".

Similarly, the definition of a complementary angle is that it adds up to 90 degrees, so we know that the complementary angle to "x" is 90 - "x".

Given that the supplementary angle to "x" is 35 degrees more than twice its complementary angle, so we can write this as an equation:

180 - x = 2(90 - x) + 35

Simplifying this equation, we get:

180 - x = 180 - 2x + 35

Adding x to both sides, we get:

Answer:

50+6.3= 56.3

Step-by-step explanation:

The data is qualitative, discrete, and at the nominal level of measurement.

The data is qualitative, as it describes the type of pizza ordered, which cannot be measured numerically.

The data is discrete, because there are only a finite number of possible values that the variable can take on, which in this case is one of the three types of pizza: Pepperoni, "Mushroom, or Black Olive.

The highest level of measurement for this data is nominal, because the numbers used to record the type of pizza do not imply any order or ranking between the categories. The numbers are simply a code to identify which type of pizza was ordered, and do not have any intrinsic numerical value or relationship between them. Therefore, the data falls into the nominal level of measurement, which is the lowest level of measurement that data can have.

Step-by-step explanation:

If a continuous random variable X is normally distributed with mean μ and variance σ², it is written as:

[tex]\boxed{X \sim\text{N}(\mu,\sigma^2)}[/tex]

Given:

Therefore, if the speeds that people drive down the Pat Bay Highway are normally distributed:

[tex]\boxed{X \sim\text{N}(90,7^2)}[/tex]

where X is the speed in km/h.

f we want to find what proportion of drivers travel between 80 and 120 km/h, we need to find P(80 ≤ X ≤ 120).

[tex]\implies \sf P(80 \leq X \leq 120)=P(X \leq 120)-P(X \leq 80)[/tex]

Converting to the Z distribution:

[tex]\boxed{\textsf{If }\: X \sim\textsf{N}(\mu,\sigma^2)\:\textsf{ then }\: \dfrac{X-\mu}{\sigma}=Z, \quad \textsf{where }\: Z \sim \textsf{N}(0,1)}[/tex]

Transform X to Z:

[tex]\sf P(X \leq 120)=P\left(Z \leq \dfrac{120-90}{7}\right)=P\left(Z \leq \dfrac{30}{7}\right)[/tex]

[tex]\sf P(X \leq 80)=P\left(Z \leq \dfrac{80-90}{7}\right)=P\left(Z \leq -\dfrac{10}{7}\right)[/tex]

Therefore:

[tex]\begin{aligned}\implies \sf P(80 \leq X \leq 120)&=\sf P\left( -\dfrac{10}{7} \leq Z \leq \dfrac{30}{7}\right)\\\\&=\sf P\left(Z \leq \dfrac{30}{7}\right)-P\left(Z \leq -\dfrac{10}{7}\right)\\\\&=\sf 0.999990892...-0.0765637255...\\\\&= \sf 0.9234271...\\\\&=\sf 92.34271...\%\end{aligned}[/tex]

Therefore, the proportion of drivers travelling between 80 and 120 km/h is 92.3% (nearest tenth).

For any given positive real number x and natural number n, there exists a unique positive real number r such that [tex]x = r^n[/tex].

Let x be a positive real number and n be a natural number. We want to show that there exists a unique positive real number r such that [tex]x = r^n[/tex]. This can be expressed mathematically as [tex]x^(1/n) = r[/tex], where r is the unique positive real number we are looking for.

To solve for r, we can take the nth root of both sides of the equation. This gives us [tex]r = x^(1/n)[/tex]. Since x is a positive real number and n is a natural number, it follows that r is also a positive real number.

Furthermore, since x is a fixed value and n is a fixed value, we can conclude that the positive real number r is unique. In other words, for any given x and n, there is only one r that satisfies the equation [tex]x = r^n[/tex].

Therefore, for any given positive real number x and natural number n, there exists a unique positive real number r such that [tex]x = r^n[/tex].

Answer:

the two integers are 11 and -8

Step-by-step explanation:

Let's call the two integers we're trying to find "x" and "y".

From the problem statement, we know two things:

x + y = 3 (the sum of the two integers is three)

x^2 + y^2 = 185 (the sum of the squares is 185)

We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for "y" in terms of "x" by subtracting "x" from both sides:

y = 3 - x

Now we can substitute this expression for "y" into the second equation:

x^2 + (3 - x)^2 = 185

Expanding the square on the left-hand side, we get:

x^2 + 9 - 6x + x^2 = 185

Combining like terms, we get:

2x^2 - 6x - 176 = 0

We can simplify this equation by dividing both sides by 2:

x^2 - 3x - 88 = 0

Now we can solve for "x" using the quadratic formula:

x = (3 ± sqrt(3^2 - 4(1)(-88))) / 2(1)

Simplifying, we get:

x = (3 ± sqrt(361)) / 2

We can ignore the negative root, since it would give us a negative value for "y". So, taking the positive root, we get:

x = (3 + 19) / 2 = 11

Now we can use the first equation to solve for "y":

y = 3 - x = 3 - 11 = -8

An equation is a part of every formula. A formula is not always an equation. In order to be solved for a variable, equations must be given. Evaluation of formulas

Given,

The student incorrectly subtracted an even integer from an odd integer and concluded that the result is odd. However, the difference between an odd integer and an even integer is always odd, which can be proven directly as follows:

Let n be any odd integer and m be any even integer. Then, by definition, n = 2k + 1 and m = 2j for some integers k and j. The difference between n and m is:

n - m = (2k + 1) - 2j
