Step-by-step explanation:

According to question, sample mean xbar = 2450 with standard deviation s = 600 and sample size n = 50

population mean = 2600 (mu)

Kindly check the attached image

T- test statistic t = = 위이 1 2450 - 2600 = -150/84.85281 = -1.77

p-value = T.DIST.2T(test statistic,n-1)

where test statistic = -1.77 and n = 50

so, p-value = T.DIST.2T(-1.77,50-1) = 0.083

Let g(x)=4x +9 and h(x)=x+2. Find the expression.<br> (h◦g)(x)

hammer [34]

So you plug in g(x) for x in h(x)
Since g(x) = 4x + 9, substitution that in
4x + 9 + 2
4x + 11

Solution: 4x + 11

An 8-car Ferris wheel is shaped like a regular octagon. Does the Ferris wheel have rotational symmetry?

sleet_krkn [62]

Answer:

Yes, it does.

Step-by-step explanation:

Every regular shaped figure will have rotational symmetry, since they are built with identical segments all around.

To find the answer, ask yourself « If I rotate the shape, is there a time where I’ll find the exact same shape again with a different angle? »

So, a square has rotational symmetry, but not a rectangle.

A equilateral triangle has rotational symmetry, but not any other type of triangle.

Given tanx=8/15 when pi < x < 3pi/2, find tan x/2.

S_A_V [24]

Answer:

$tan(x/2)=-4$

Step-by-step explanation:

we know that

The angle x belong to the III quadrant -----> given problem

step 1

Find the angle x

$x=arctan(8/15)=28.07\°$

Remember that the angle x belong to the III Quadrant

$x=28.07\°+180\°=208.07\°$

step 2

Find angle x/2

$x/2=208.07\°/2=104.035\°$

step 3

Find tan(x/2)

$tan(104.035\°)=-4$
