2. H1: u <500

3. One sample t test

Step-by-step explanation:

1. The null hypothesis in this question would be

H0: u = 500

2. The alternative hypothesis would be

H1: u < 500

3. The test that we are going to be using is the one sample t test. This test is used to test hypothesis. It would make a comparison of h0 to the mean of the sample. Now we are using this here because the sample standard deviation was given

An equilateral triangle has a side length of 1.4x + 2 inches

a side length of 0.5x + 2 inches. The perimeters are equal. What is the side length
of the triangle? What is the side length of the hexagon? Show your work.
op
SOLUTION

Answers

Answer:

The Perimeter of an equilateral triangle = 1.4x+2+1.4x+2+1.4x+2

                                                                  = 4.2x+6

The Perimeter of a regular hexagon = 0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2

= 3x+12

Given that the perimeters are equal

4.2x+6 = 3x+12

4.2x - 3x = 12-6

1.2x = 6

x = 6/1.2

x=5

The side length of the triangle = 1.4x+2

                                                   = 1.4 (5) +2

                                                   = 9 inches

The side length of hexagon = 0.5x+2

                                              = 0.5(5) +2

                                              = 4.5inches

Since she can speak more than 7, you can mentally get rid of A and B because the circles on the number line show less than or equal to and more than or equal to, and we already know she can speak more than 7 languages.

So between the less than or greater than symbol you need to pick the line that has the arrow pointing in the direction of the greater than symbol because she can speak more than 7 languages

The answer would be C because greater than symbols point in the same direction of the line >  

What is the value of x?

Answers

Answer: x = 140 degrees

Steps:
360 = 40 + 40 + x + x
360 = 80 + x + x
360 = 80 + 2x
360 - 80 = 2x
280 = 2x
280/2 = x
140 = x

Check:
x = 140
40 + 40 + x + x
40 + 40 + 140 + 140 = 360
360 = 360 ✅

In the figure below, the triangles are similar. Find the ratio of their areas from larger to smaller.

Answers

Area of larger triangle is A1
21:14=x:8
x=21•8/14
x=168/14
x=12
x=base of triangle
A2=h•b/2
21^2=6^2+h^2
441=36+h^2
h^2=441-36
h^2=405
h= √405
h=20.12

A1=12•20.12/2
A1=6•20.12
A1=120.72


Area of smallest triangle is A2
A2=b•h/2
h=?
14^2=4^2+h^2
196=16+h^2
h^2=196-16
h^2=180
h= √180
h=13.42
A2=8•13.42/2
A2=4•13.42
A2=53.68

find degree measures of marked angles in fig 5.47​

Answers

Answer:

50+P=125 exterior angle of the triangle is equal to the sum of two opposite interior angle

P=125-50=75°

q+125=180 linear pair

q=180-125=55°

r=q=55° vertically opposite angle

s+85=125 exterior angle of the triangle is equal to the sum of two opposite interior angle

s=125-85=40°

s+t=180 linear pair

t=180-40=140°

u=s=40° vertically opposite angle

w=65° vertically opposite angle

v+u+w=180 sum of interior angle of the triangle is 180

v+40+65=180

v=180-105=75°

x+65=180 linear pair

x=180-65=115°

Anthony buys a guitar for $80. What is the final price he pays after an 8% sales tax?

Answers

Answer:

$86.4

Step-by-step explanation:

You already know that Anthony spent $80 on a guitar and has to pay 8% sales tax so you have to find 8% of $80 and add it to $80 because that is how much he has to pay. 8% of 80=6.4. 6.4+80=86.4 so that is how you get your answer.

Consider random samples of size 80 drawn from population A with proportion 0.48 and random samples of size 66 drawn from population B with proportion 0.13 . (a) Find the standard error of the distribution of differences in sample proportions, . Round your answer for the standard error to three decimal places. standard error

Answers

Answer:

Standard error = 0.070

Step-by-step explanation:

Formula for the standard error of the distribution of differences in sample proportions is;

σ_(A - B) = √((p_a^(1 - p_a^)/n_a) + (p_b^(1 - p_b^)/n_b))

We are given;

p_a^ = 0.48

n_a = 80

p_b^ = 0.13

n_b = 66

Thus;

σ_(A - B) = √((0.48(1 - 0.48)/80) + (0.14(1 - 0.13)/66))

σ_(A - B) = √0.00496545455

σ_(A - B) = 0.070
