Compute the standardized test statistic, χ 2, to test the claim σ 2 = 25.8 if n = 12, s 2 = 21.6, and α = 0.05.

Answer:

t=v/dl

Step-by-step explanation:

v=dlt you want the t to be by itself on one side

t=v/dl so divide the other side by d and l

Answer:

f⁻¹(x) = (x + 2)/3

Step-by-step explanation:

I'm going to assume the question is asking for the inverse. If that is the case, you want to switch x and y in the equation and solve for y.

f(x) = 3x - 2

x = 3f(x) - 2

x + 2 = 3f(x)

(x + 2)/3 = f⁻¹(x)

Therefore, the inverse is f⁻¹(x) = (x + 2)/3.

Answer:

The answer is A.

Step-by-step explanation:

To gain support of the Chinese government for their policies.

The inverse of y=2/3x-5 is  3/2x + 15/2

An inverse is a function that serves to “undo” another function.

Given a function, y = 2/3x -5

Exchange x and y

x = 2/3y -5

Solve for y

Add 5 to each side

x+5 = 2/3y-5+5

x+5 = 2/3y

Multiply each side by 3/2

3/2(x+5) = 3/2*2/3y

3/2x + 15/2 =y

Hence, The inverse is 3/2x + 15/2

Answer:

124.8

Step-by-step explanation:

The equation for the area of a triangle is base length (12) multiplied by the height length (10.4) divided by 2. Two of the same triangle create a rectangle, and by multiplying the base and the height you find this rectangle. To find the are of the triangle, you just need to remove the other triangle (divide by 2).

after 4 hours, the water level decreased by 8 feet

which is -8

Therefore -8/4 = -2 change in water level every hour

Answer:

The constant rate of change is 2 feet every hour.

Step-by-step explanation:

Since the level of the water was at 10 feet at 2 pm, and the water at 6 pm was at 2 feet, the water level dropped 8 feet in 4 hours.

With this information we can create the ratio 4:8 and when you simplify the ratio down to 1, you get 1:2

1 Representing 1 hour

2 Representing 2 feet

Every hour, the water level drops 2 feet.

Step-by-step explanation:

The percentage of numbers randomly generated by Taylor's computer that is less than 0.5 will be 12.5% .

A percentage is a minimum number or ratio that is measured by a fraction of 100.

A numerical distribution with continuous results is a density curve. A density curve is, in other terms, the graph of a continuous distribution. Which implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete).

Also the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).

The percentage of numbers randomly generated by Taylor's computer are less than 0.5 is;

P(0≤X≤0.5)

= 1/4 (0.5 - 0)

= 1/4 (0.5)

= 0.125

That is 12.5%

Hence, The percentage of numbers randomly generated by Taylor's computer that is less than 0.5 will be 12.5% .

#SPJ5

Answer:

-28

Step-by-step explanation:

The big thing to remember here is

Slope=Rise/Run

We can put x for the run and get this equation

21/x=-3/4

From here it gets really easy. To find the value of x we can change -3/4 into 21/-28 because in this case we need a common numerator. 21/x=21/-28 and it is obvious that x=-28

Hope this helped let me know if you have questions.
