Answer:

D - 36 square inches

Step-by-step explanation:

8 x 9 = 72

72 - 2 = 36

Answer:

y+2=-4(x+9)

Step-by-step explanation:

Point slop form: y-y₁=m(x-x₁)

X-coordinate is -9 and the y-coordinate is -2.

slope is -4.

y-(-2)=-4(x-(-9))

y+2=-4(x+9)

Answer: Sin(570) = - 1/2

Step-by-step explanation:

570 as an angle contains 1 complete revolution of the terminal arm. The terminal arm begins at the origin and the other (in this case swings around until it records 570° turning around the x axis in an anticlockwise direction.

The exact value of Sin(570°) is,

⇒ sin (570°) = - 1/2

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Since,

570 as an angle contains 1 complete revolution of the terminal arm. The terminal arm begins at the origin and the other (in this case swings around until it records 570° turning around the x axis in an anticlockwise direction.

Anticlockwise means going from 12 o'clock to 9 o'clock to 6 o'clock then 3 o'clock and back to 12 o'clock.

We keep on subtracting 360 until we get a number between 0 and 360 inclusive.

Written this way 0 ≤∅≤360

570 - 360 = 210°

So we need to find the equivalent of 210°

210° = 180° + 30°

This means that ∅ is 30° below the x axis in the 3rd quadrant.

Sin(30) = 1/2

In the third quadrant, the sine is minus. so

sin(210°) = - 1/2

Thus, The exact value of Sin(570°) is,

⇒ sin (570°) = - 1/2

The least number of miles Ian skated on a day in July is greater than the least number of miles Ian skated on a day in August.

The statements that best supported by the dot plot are;

The least number of miles Ian skated on a day in July is greater than the least number of miles Ian skated on a day in August.

The range of the number of miles Amanda skated in August is; 1 to 3

The range of the number of miles Amanda skated in July is; 1 to 4

IT is found that range of the number of miles Amanda skated in August is less than the range of the number of miles she skated in July.

The distribution of data for the month of July is almost symmetrical but the data in August is not.

The mode of the number of miles Amanda skated in July is equal to the mode of the number of miles skated in August which is also a true statement.

Answer:

We need to develop a one-tail t-student test ( test to the right )

We reject H₀  we find evidence that student spent more than 24,5 hours on the phone

Step-by-step explanation:

Sample size  n = 15     n < 30

And we were asked if the mean is higher than, therefore is a one-tail t-student test ( test to the right )

Population mean   μ₀  = 24,5

Sample mean   μ  =  25,7

Sample standard deviation s = 2

Hypothesis Test:

Null Hypothesis      H₀                             μ  =  μ₀

Alternative Hypothesis     Hₐ                  μ  >  μ₀

t (c) =  ?

We will define CI = 95 %  then   α = 5 %   α = 0,05    α/2 =  0,025

n = 15     then degree of freedom    df = 14

From t-student table  we get:  t(c) = 2,1448

And  t(s)

t(s) = ( μ  -  μ₀  ) / s/√n

t(s) = (25,7 - 24,5) /2/√15

t(s) = 2,3237

Now we compare   t(c)   and  t(s)

t(c)  =  2,1448         t(s)  = 2,3237

t(s) > t(c)

Then we are in the rejection region we reject H₀   we have evidence at 95% of CI that students spend more than 24,5 hours per week on the phone

Step-by-step explanation:

[tex]u = \frac{3t}{4} + 2[/tex]

[tex]u - 2 = \frac{3t}{4} [/tex]

[tex] \frac{4}{3} (u - 2) = t[/tex]

[tex] \frac{4}{3} u - \frac{8}{3} = t[/tex]

From the given information, t as the subject of the formula;  [tex]t = \dfrac{4U}{3} - \dfrac{8}{3}[/tex]

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given;

U = 3t/4 + 2

We have to make t the subject of the formula.

So,

[tex]U = \dfrac{3t}{4} + 2 \\\\U - 2= \dfrac{3t}{4}\\\\(U - 2) 4= 3t\\\\3t = 4U - 8\\\\t = \dfrac{4U}{3} - \dfrac{8}{3}[/tex]

The miles that Jordan run after 6 days will be 5 1/4 miles.

This relates to a fraction. A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

Here, Jordan runs to the end of his street and back home every day and the total distance of a trip to the end of the street and back home is 7/8 mile.

The miles that Jordan run after 6 days will be:

= 7/8 × 6

= 42 / 8
