Zachary completes a hypothesis test and finds that he rejects the null hypothesis. Which statement gives a reason for rejectingthe null hypothesis?
The Z-statistic is less than 0.
The z-statistic lies in the critical region.
The Z-statistic lies outside the critical region.
The z-statistic is greater than 0.

Answers

Answer 1

Answer:

Answer:

The z-statistic lies in the critical region

Step-by-step explanation:

When a hypothesis test is performed, the decision to reject or not reject the null hypothesis is made on basis of following observations:

If the z-statistic falls in the critical or rejection region, there is enough evidence to reject the Null Hypothesis
If the z-statistic falls outside the critical or rejection region, there is not enough evidence to reject the Null Hypothesis.

In the given statement Zachary rejects the Null Hypothesis, this means the z-statistic she calculated must have been inside the critical or rejection region. Hence the correct answer would be:

The z-statistic lies in the critical region

Answer 2

Answer:

Answer: b) The z-statistic lies in the critical region.

Write 25,000 in expanded notation using exponents

Answers

25,000 in the expanded notation is 2.5 × 10⁴

What is an expanded notation?

Expanded notation, also called expanded form, is a handy way to write numbers that show the place value of each digit.

It looks like an addition problem and will help you break numbers down and understand their place value.

Given is a number 25000 we need to convert it into an expanded form,

25000 = 25 × 10³ = 2.5 × 10⁴

Hence, 25,000 in the expanded notation is 2.5 × 10⁴

A+b = 30 a:b is equivalent to 2:3. What is a& b

Answers

one way is to use brute force (find bigger equivilent ratios and add them)
2:3

to make them bigger, we multiply both by the same number
2:3
2+3=5 nope

2:3 times 2 to both=4:6
add
4+6=10
we can just add the numbers before multiplying and then multiply after

2+3=5
5 times what=30
divide both sides by 5
6=what
we need to multiply each by 6
2:3 times 6 to both =12:18
12+18=30

a=12
b=18

Final answer:

The given equations are simultaneous equations. We need to find the values of 'a' and 'b'. To do so, we convert the ratio into equation and substitute into the original equation. Then solving will give 'a = 12' and 'b = 18'.

Explanation:

In this question, we are given two simultaneous equations to solve for the unknowns 'a' and 'b'. The given equations are 'a + b = 30' and the ratio 'a:b' is equivalent to '2:3'.

Since the ratio 'a:b' is equal to '2:3', we can consider 'a' to be '2x' and 'b' to be '3x'. Substituting this into the first equation, we get '2x + 3x = 30', which simplifies to '5x = 30'. Solving for 'x', we find that 'x = 6'.

Substituting 'x = 6' into the expressions for 'a' and 'b', we find that 'a = 2*6 = 12' and 'b = 3*6 = 18'. Therefore, the solutions to the equations are 'a = 12' and 'b = 18'.

Jared is putting a new deck off the kitchen. The deck will be 94.45 inches deep. He will use 16 boards that are each 5.7 inches wide. He has to leave a small space between the boards. If the 15 spaces between the boards are all equal, how wide will they be?

Answers

16 boards that are 5.7 inches wide each make a total of 91.20 inches.

16
x 5.7
112
+800
91.2 inches

Since the deck itself is 94.45 inches deep, we can subtract 91.2 from the number:

94.45
-91.20
3.25 inches.

Finally, we divide 3.25 by 15, since that's the amount of spaces we want and they have to be equal:

3.25/15= .21667

We'll round that to two numbers, so we'll end up with .22.

Your final answer is .22 inches wide for each space.
