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

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:

$16,341< μ <$22,459.

Step-by-step explanation:

The formula for calculating confidence interval is expressed as;

CI = xbar±(z×s/√n)

xbar is the mean tuition

z is the z score at 90% CI

s is the standard deviation

n is the sample size

Given

xbar = $19,400

s = $11,000

n = 35

z = 1.645

Substitute into the formula for calculating confidence interval

CI = xbar±(z×s/√n)

CI = 19400±(1.645×11000/√35)

CI = 19400±(1.645×11000/5.916)

CI = 19400±(1.645×1859.36)

CI = 19400±3058.65

CI = [19400-3,058.65, 19400+3,058.65]

CI = [16,341.35, 22,458.65]

CI = [16,341, 22,459] to nearest whole number.

Hence a 90% confidence interval for the mean tuition for all colleges and universities is 16,341< μ <22,459.

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

= 5 1/4 miles.

Answer:

a) as the time increases by one year the hight of the tree is increasing by 15

b)

h=90+(t*15)

Answer:

f(x) = 2(x + 4)² - 2

Step-by-step explanation:

Equation of quadratic function whose vertex is (h, k),

f(x) = a(x - h)² + k

Equation of the function with vertex (-4, -2) shown in the graph will be,

f(x) = a(x + 4)² - 2

This graph is passing through a point (-6, 6) also,

6 = a(-6 + 4)² - 2

6 + 2 = a(-2)²

a = [tex]\frac{8}{4}[/tex] = 2

Therefore, quadratic function is f(x) = 2(x + 4)² - 2

It would still be the same 3 hens in 9 days.

Answer:

1 hen

Step-by-step explanation:

For this problem, we will simply make the assumption that 1 hen can lay 1 egg every 3 days. Using this, let's build a proportion:

1 hen / 1 egg / 3 days == x hens / 3 eggs / 9 days

Notice our rate ( 1 egg / 3 days ) remains constant. This we can conclude based on our assumption that there is only 1 hen laying eggs.

If our rate was different, then we would have additional hens proportional to the rate.

Cheers.

Answer: The Slope Intercept form is y=-6x-23

The linear equation in slope intercept form will be y = -6x - 23.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line is given as below:-

y = mx + c

Here, m is the slope of the line and c is the intercept of the line.

Given that the slope of the line is -6 and the line passes through the point (-4, 1). The equation of the line will be calculated as below:-

y = -6x + c

1 = ( -6 x -4 ) + c

c = 1 - 24

c = -23

Write the equation now:-

y = mx + c

y = -6x - 23

Therefore, the linear equation in slope intercept form will be y = -6x - 23.
