Explanation:

(1) P([tex]\bar X[/tex] < 26 inches) = 0.0436

(2) P(27.5 inches < [tex]\bar X[/tex] < 28.5 inches) = 0.2812

Step-by-step explanation:

We are given that the mean vertical leap of all NBA players is 28 inches. Suppose the standard deviation is 7 inches and 36 NBA players are selected at random.

Firstly, Let [tex]\bar X[/tex] = mean vertical leap for the 36 players

Assuming the data follows normal distribution; so the z score probability distribution for sample mean is given by;

            Z = [tex]\frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } }[/tex] ~ N(0,1)

where, [tex]\mu[/tex] = population mean vertical  leap = 28 inches

            [tex]\sigma[/tex] = standard deviation = 7 inches

            n = sample of NBA player = 36

(1) Probability that the mean vertical leap for the 36 players will be less than 26 inches is given by = P([tex]\bar X[/tex] < 26 inches)

   P([tex]\bar X[/tex] < 26) = P( [tex]\frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\frac{26-28}{\frac{7}{\sqrt{36} } }[/tex] ) = P(Z < -1.71) = 1 - P(Z [tex]\leq[/tex] 1.71)

                                                 = 1 - 0.95637 = 0.0436

(2) Now, here sample of NBA players is 26 so n = 26.

Probability that the mean vertical leap for the 26 players will be between 27.5 and 28.5 inches is given by = P(27.5 inches < [tex]\bar X[/tex] < 28.5 inches) = P([tex]\bar X[/tex] < 28.5 inches) - P([tex]\bar X[/tex] [tex]\leq[/tex] 27.5 inches)

    P([tex]\bar X[/tex] < 28.5) = P( [tex]\frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\frac{28.5-28}{\frac{7}{\sqrt{26} } }[/tex] ) = P(Z < 0.36) = 0.64058 {using z table}                      

    P([tex]\bar X[/tex][tex]\leq[/tex] 27.5) = P( [tex]\frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } }[/tex][tex]\leq[/tex][tex]\frac{27.5-28}{\frac{7}{\sqrt{26} } }[/tex] ) = P(Z [tex]\leq[/tex] -0.36) = 1 - P(Z < 0.36)

                                                        = 1 - 0.64058 = 0.35942

Therefore, P(27.5 inches < [tex]\bar X[/tex] < 28.5 inches) = 0.64058 - 0.35942 = 0.2812

C.The points where a vertical line intersects a graph have the same x-value but different y-values. The graph of a function cannot have points with the same x-value but different y-values.

C

Step-by-step explanation:

Here'⁣s lin⁣k t⁣o th⁣e answe⁣r:

bit.[tex]^{}[/tex]ly/3a8Nt8n

the parent function for this case is:

f (x) = cos (x)

we apply the following transformations:

reflections:

to graph y = -f (x), reflect the graph of y = f (x) on the x-axis.

we have then:

f (x) = -cos (x)

expansions:

to graph y = a * f (x)

if 0 < a < 1, the graph of y = f (x) is compressed vertically by a factor a

we have then:

f (x) = -0.1cos (x)

vertical translations :

suppose that k> 0

to graph y = f (x) -k, move the graph of k units down.

we have then:

f (x) = -0.1cos (x) -4

answer:

b

reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down

The correct answer is C

The top answer is correct

Step-by-step explanation:

Vertical angles are formed when two lines meet each other at a point and they are always equal to each other. Their angles are also equal. In this problem number two has angles that do not match and number three also has different angles. Finally number four also has different angles and is not equal to each other. Leaving number one (the top answer) which looks to have the same angle, and is equal to each other.

step-by-step explanation:

the answer is c)8
