5) What does QRST → Q'R'S'T' mean?

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

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

Step-by-step explanation:

The unit rate will be the amount associated with 1 unit: $0.99.

Answer:

A = 1.5386

Step-by-step explanation:

Quarter circle area formula:

A = (πr²)/4

A= (π1.4²)/4

A = (3.14*1.96)/4

A = (6.1544)/4

A = 1.5386

Answer: C

Step-by-step explanation:

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 >

Step-by-step explanation:

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°

Answer:

Step-by-step explanation:

y = 4x + 1

Slope of line = 4

Slope of perpendicular to line = -¼

Point-slope equation for line of slope -¼ that passes through (12, -7):

y+7= -¼(x-12)

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.

Answer:

36

Step-by-step explanation:

its a square so all sides are equal so do 6 times 6

Answer: 36 cm squared

Step-by-step explanation:

first, we know squares have all equal sides, which means the square has 6cm for each side

we then multiply the base x height which equals 36

finally, since we are finding area, we put a “squared” symbol, or the word “squared”

Answer:

Step-by-step explanation:

Volume = πr²h = π·8²·17 = 1088π ≅ 3,418.1 ft³

Since this cylinder has a radius of 8 feet, its volume is equal to 3,418.5 cubic feet.

Given the following data:

Radius of cylinder = 8 feet.

Height of cylinder = 17 feet.

Mathematically, the volume of a cylinder is given by this formula:

V = πr²h

Where:

Substituting the given parameters into the formula, we have;

V = 3.142 × 8² × 17

V = 3.142 × 64 × 17

V = 3,418.5 cubic ft.

Answer:

1. H0: u = 500

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
