All of the values fall within____standard deviation(s) of the mean.

Answers

Answer 1

Using z-scores, it is found that all of the values fall within 2.46 standard deviations of the mean.

What is the z-score formula?

The z-score of a measure X of a variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean.

In this problem, the farthest variable from the mean is of $29.95, hence X = 29.95 and:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{29.95 - 22.58}{3}[/tex]

Z = 2.46.

Hence, all of the values fall within 2.46 standard deviations of the mean.

17. The velocity, in meters per second, of a runner is given by the function v(t)=11 et +5t. A. Find the acceleration of the runner at time t = 3 seconds. Include the proper units. B. Find the position function given that the runner starts at a distance of 6 meters.​

Answers

Answer:

a) a= 5 m/s^2

b) P(t) = 2.5 t^2 + 11 t + 6

Step-by-step explanation:

The velocity function is V(t) = a*t + Vo

In this case: V(t) = 5t + 11

It means the constant acceleration a = 5 m/s^2

while the initial velocity (at time t=0s) is 11 m/s

The position function is:

P(t) = 1/2 A*t^2 + Vo*t + Po

In this case:

P(t) = 2.5 t^2 + 11 t + 6

Answers

The approximate x-coordinates of the points of intersection of the given curves are 0 & 1.76, and the volume of the solid when rotated about the x-axis is 3.15 cubic units

Part A: The points of intersection

The equations are given as:

y = ∛2x - x²

y = x²/(x² + 1)

See attachment for the graph of the above curves (equation)

From the attached curve, we have the following points of intersection

(x,y) = (0,0) and (1.76,0.76)

Remove the y coordinates

x = 0 and 1.76

Hence, the approximate x-coordinates of the points of intersection of the given curves are 0 and 1.76

The volume of the solid when rotated about the x-axis

The volume of the solid is calculated using:

V = π(R² - r²)

Where R and r are the outer and the inner radii, respectively.

In this case;

R = ∛2x - x²

r = x²/(x² + 1)

Using a calculator, we have:

V = 3.15

Hence, the volume of the solid when rotated about the x-axis is 3.15 cubic units

11 4/5 divided by 3 1/5

A) 3
B) 3 1/2
C) 7/2
D) 4

Answers

Answer:

Step-by-step explanation:

The two given numbers both have the denominator 5,  Thus the quotient quickly reduces:

11 4/5 becomes 59/5 and 3 1/5 becomes 16/5.  Dividing the first expression by the second yields 59/16, which can't be reduced.

However, 59 = 48 + 11, so 59/16 = 48/16 + 11/16, which is approximately 3 1/2 (from either Answer B or Answer C).

The exact answer is 3 11/16; B and C are identical and are closer to 3 11/16 thn 3 or 4.

Hope This Helps!!!

Answer:

25.1

Step-by-step explanation:

Before finding the value of x which is the base in the right triangle, we must have to find the perpendicular in the left angle triangle.

So, In the left triangle,

→ (Base)² + (Perpendicular)² = (Hypotenuse)²

→ (10)² + (Perpendicular)² = (16)²

→ (Perpendicular)² = (16)² – (10)²

→ (Perpendicular)² = 256 – 100

→ (Perpendicular)² = 156

→ Perpendicular = √(156)

→ Perpendicular = 12.4

Now, In the right triangle, we have :

→ (Base)² + (Perpendicular)² = (Hypotenuse)²

→ (x)² + (12.4)² = (28)²

→ (x)² = (28)² – (12.4)²

→ (x)² = 784 – 153.7

→ (x)² = 630.3

→ x = √(630.3)

→ x = 25.1

Therefore,

The value of x is 25.1

Segment AB has endpoints at A(-7,2) and b(9,-6). Point P lies on AB such that AP:BP=3:1

Determine the coordinates of P

Answers

The coordinates of the point P which divides the line segment AB made by the points A(-7,2) and B(9,-6) is  (x,y) = (5,-4)

What is the coordinate of the point which divides a line segment in a specified ratio?

Suppose that there is a line segment [tex]\overline{AB}[/tex]such that a point P(x,y) lying on that line segment [tex]\overline{AB}[/tex] divides the line segment  [tex]\overline{AB}[/tex] in m:n, then, the coordinates of the point P is given by:

[tex](x,y) = \left( \dfrac{mx_2 + nx_1}{m+n} , \dfrac{my_2 + ny_1}{m+n} \right)[/tex]

where we have:

the coordinate of A is [tex](x_1, y_1)[/tex]and the coordinate of B is [tex](x_2, y_2)[/tex]

We're given that:

Coordinate of A is [tex](x_1, y_1)[/tex] = (-7,2)Coordinate of B is [tex](x_2, y_2)[/tex] = (9.-6)The point P lies on AB such that AP:BP=3:1 (so m = 3, and n = 1)

Let the coordinate of P be (x,y), then we get the values of x and y as:

[tex](x,y) = \left( \dfrac{mx_2 + nx_1}{m+n} , \dfrac{my_2 + ny_1}{m+n} \right)\\\\(x,y) = \left( \dfrac{3(9) + 1(-7)}{3+1} , \dfrac{3(-6) + 1(2)}{3+1} \right)\\\\(x,y) = \left( \dfrac{20}{4} , \dfrac{-16}{4} \right) = (5,-4)[/tex]

Thus, the coordinates of the point P which divides the line segment AB made by the points A(-7,2) and B(9,-6) is  (x,y) = (5,-4)

First of all, we need to find the slope. In order to find the slope, we'll use the following formula :

Now that we know the slope, finding the point-slope equation is a piece of cake.

2. A light fixture contains 6 light bulbs. With normal use, each bulb has a 0.85
chance of lasting for at least 4 months. What is the theoretical probability that
all 6 bulbs will last for 4 months? Round to the nearest whole percent.

Answers

Using the binomial distribution, it is found that there is a 0.38 = 38% theoretical probability that all 6 bulbs will last for 4 months.

What is the binomial distribution formula?

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.

In this problem, we have that:

There are 6 bulbs, hence n = 6.Each bulb has a 0.85 chance of lasting for at least 4 months, hence p = 0.85.

The probability that all 6 bulbs will last for 4 months is P(X = 6), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 6) = C_{6,6}.(0.85)^{6}.(0.15)^{0} \approx 0.38[/tex]
