Answer:

The probability for possibilities of x between P(X>4) and P(6.72<X<10.16)  is 0.5987 and 0.2351

X is N(5, 16)

means that, Z=(x-mean)/√variance = (x-5)/√4

=(x-5)/2

that is, Z is standard normal.

Then, by symmetry of the standard normal curve,

P(X>4)=P(X−5>4−5)

=P(X−54>4−54)

= P(Z>−14)

=P(Z>−.25)

=P(Z<.25)

= 0.5987.

Similarly

P(6.72<X<10.16)

= P(6.72−5<X−5<10.16−5)

=P(6.72−54<10.16−54)

=P(0.43<Z<1.29)

=P(Z<1.29)−P(Z<.43)

=.9015−.6664

= 0.2351.

Therefore, The probability for possibilities of x between P(X>4) and P(6.72<X<10.16)  is 0.5987 and 0.2351

Answer:

3/20.

Step-by-step explanation:

Answer:

3. f(3) = 16

4. h(3) = 4

Step-by-step explanation:

3.

f(x) = x² + 7

f(3) = 3² + 7

f(3) = 16

4.

h(x) = 12/x

h(3) = 12/3

h(3) = 4

The values of u and v in the table are directly proportional to each other with a constant k is 3.

When x increases, y increases; when x decreases, y decreases.

The opposite of direct is indirect. When x rises, y falls; when x falls, y rises.

If you said y is directly proportional to x,

it would be y/x=k or y=kx.

Here given that,

u = 0.25, 0.3, 0.1

v = 0.75, 0.9, 0.3

So here v = 3u

That is v = 3 x 0.25

v = 0.75

Hence u and v are directly proportional with a constant k = 3

When v = 2/5

To find u,

v = 3u

2/5 = 3u

u = 2/15

When u = 3/7

Then v = 3 x 3/7

v = 9/7

The value of p and w in the triangle are 6 units and 13√3 units respectively

Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.

In the triangle, we have angles of 30° and 90°

Using trigonometric ratios:

sin 30° = (2p+1)/(6p-10)     [sin = opp/hyp]

1/2 = (2p+1)/(6p-10)

1/2(6p-10) = (2p+1)

3p -5 = 2p + 1

3p -2p = 1+5

p = 6 units

cos 30° = w/(6p-10)       [cos = adj/hyp]

(√3)/2 = w/(6p-10)

(√3)/2 = w/((6×6) -10)

(√3)/2 = w/(36 -10)

(√3)/2 = w/26

w = (√3)/2 × 26

w = 13√3 units

We have to recall that what makes the right angle triangle unique is the fact that one of the angles that we find in the triangle is 90 degrees. We have to recall that the sum of the angles that we have in a triangle is 180°.

Hence we have;

α = 180 - (90 + 34)

The distance travelled by larger circular wheel is 2π(R-r) more than the distance travelled by old tires.

What is a circle?

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.

The equation of circle in the plane is given as:

(x-h)^2 + (y-k)^2 = r^2

where (x, y) are the coordinate points

(h, k) is the coordinate of the center of a circle

and r is the radius of a circle.

and Area of circle = πr²

Circumference of circle=2πr

Now

let radius of old tires =r

radius of new tires =R

distance travelled by new tire in one rotation= 2πR

distance travelled by old tire=2πr

Hence,

Answer:

the slope is -4

Step-by-step explanation:

The solution's f[x] means f(x)=0 when x is not in [−2,2]

The answer to [-2,2] is: f(x)dx=P(X∈dx)=2∗(2−|x|)dx4∗(12∗2∗2)=14(2−|x|)dx

Consequently, f(x)=14(2|x|) on [2,2]

and if not, f(x)=0

For [2,0], it is 14(2+x), while for [2,0], it is 14(2-x).

I discovered a formula for the uniform distribution U=X for (a,b), however, I don't believe this is right since the answer would then be X+24 without X being an absolute value. It also doesn't apply to other questions of a similar nature.

The value of the evaluated iterated integral is 0.1202.

As per the given data the iterated integral is [tex]I & =\int_0^1 \int_0^{s^6} \cos \left(s^7\right) d t d s[/tex].

Here we have to evaluate the given iterated integral.

The definite integral of a real-valued function f(x) with respect to a real variable x on an interval [a, b] is expressed as[tex]$\int_a^b f(x) d x$[/tex] = F(b) - F(a)

Here,

[tex]$\int=$[/tex] Integration symbol

a = Lower limit

b = Upper limit

f(x) = Integrand

dx = Integrating agent

Thus, [tex]$\int a b f(x) d x$[/tex] is read as the definite integral of f(x) with respect to d x from a to b.

Indefinite integrals are implemented when the boundaries of the integrand are not specified.

[tex]I & =\int_0^1 \int_0^{s^6} \cos \left(s^7\right) d t d s[/tex]

Integrate the given iterated integral.

We get:

[tex]& =\int_0^1 \cos \left(s^7\right)\left(\int_0^{s^6} d t\right) d s[/tex]

[tex]& =\int_0^1 \cos \left(s^7\right) \times[t]_0^{s^6} d s . \\[/tex]

[tex]& =\int_0^1 \cos \left(s^7\right) \times\left(s^6-0\right) d s . \\[/tex]

[tex]& =\int_0^1 s^6 \cos \left(s^7\right) d s[/tex]

Say [tex]s^7=t[/tex]                 when s = 0

[tex]\Rightarrow \frac{d t}{d s}=7 s^6 \quad$[/tex]                          t = 0  

[tex]\Rightarrow \frac{d t}{7}=s^6 d s[/tex]              when s = 1.....   t = 1

Replace the assumed terms.

Then we get:

[tex]$I=\int_0^1 \cos (t) \frac{d t}{7}$[/tex]

[tex]$=\frac{1}{7} \int_0^1 \cos (t) d t$[/tex]

[tex]$=\frac{1}{7}[\sin (t)]_0^1=\frac{1}{7}[\sin (1)-\sin (0)]$[/tex]

[tex]=\frac{\sin (1)}{7}$[/tex]

[tex]\int_0^1 \int_0^{s^6} \cos \left(s^7\right) d t d s[/tex] = 0.1202

The the experimental probability of rolling the given result that a number more than 3 is D. 0.44

Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur or that a particular statement is true.

The following observations can be gotten based on the information:

1 = 32

2 = 36

3 = 44

4 = 20

5 = 30

6 = 38

Therefore, probability = sum of observation (3,4 and 5) / total no of observation

= 20 + 30+ 38 / 200

Answer: To find the X and Y components of the 15N weight of the birthday cake, we can use trigonometry. We know that the angle of inclination of the table is 23° above the horizontal.

We can use the tangent function to find the X component of the weight, which is the component that is parallel to the table.

X = 15N * tangent (23°)

We can use the sine function to find the Y component of the weight, which is the component that is perpendicular to the table.

Y = 15N * sine (23°)

By applying these formulas and plugging in the angle and weight we can find the respective X and Y components.

The number of sides that the polygon has is given as follows:

24 sides.

A regular polygon is a polygon in which all side lengths have the same measure, hence all the internal angles of the polygon will also have the same measure.

The sum of the internal angle measures of a polygon of n sides is given as follows:

S(n) = (n - 2) x 180º.

For a regular polygon of n sides, with n angles of equal measure, the measure of each interior angle is given as follows:

I = (n - 2) x 180/n.

In the case of the center of the polygon, the sum of the internal angles is of 360º, hence the number of sides n can be obtained as follows:

n  = 360/I.

For this problem, the internal angle measure is given as follows:
