A line passes through the points (4, 9) and (-9, -5).
Find the slope of the line.

Answer:

a

Step-by-step explanation:

hii :)

so we cant add n numbers and not n numbers.

knowing this, we have to somehow put them together.

2n-3+n+4

adding the 2n and n together: 3n-3+4

add -3+4=1

resulting in

3n+1, so the answer is A because n is a full basket and 3 times that is 3 full baskets. (with an extra 1 apple)

i hope this was easy to understand!

Answer:

The appropriate set of hypothesis for his significance test is null hypothesis [tex]H_0: p = 0.06[/tex] and alternate hypothesis [tex]H_1: p \neq 0.06[/tex]

Step-by-step explanation:

Elliot read a report from a previous year saying that 6%, percent of adults in his city biked to work. He wants to test whether this proportion has changed.

At the null hypothesis we test if the proportion is still the same, that is, of 6%. So

[tex]H_0: p = 0.06[/tex]

At the alternate hypothesis, we test if the proportion has changed, that is, it is different of 6%. So

[tex]H_1: p \neq 0.06[/tex]

What is an appropriate set of hypotheses for his significance test?

The appropriate set of hypothesis for his significance test is null hypothesis [tex]H_0: p = 0.06[/tex] and alternate hypothesis [tex]H_1: p \neq 0.06[/tex]

Answer:

The right solution is "0.15%".

Step-by-step explanation:

The given values are:

Mean,

[tex]\bar{x}=54.82[/tex] $

Standard deviation,

[tex]s = 8.95[/tex] $

[tex]P(X>81.67)[/tex]

Now,

= [tex]P(z>\frac{81.67-\bar{x}}{s} )[/tex]

On substituting the values, we get

= [tex]P(z>\frac{81.67-54.82}{8.95} )[/tex]

= [tex]P(z>\frac{26.85}{8.95})[/tex]

= [tex]P(z>3)[/tex]

By using the table, we get

= [tex]0.0015[/tex]

= [tex]0.15[/tex]%

Answer:

Average number of people ride ferry boat = 62 or 63 people

Step-by-step explanation:

Given:

Number of people ride ferry boat

58 59 60 61 62 63 64 65 66 67

Find:

Average number of people ride ferry boat

Computation:

Average mean = Sum of all observation / Number of observation

Average number of people ride ferry boat = [58 + 59 + 60 + 61 + 62 + 63 + 64 + 65 + 66 + 67] / 10

Average number of people ride ferry boat = [625] / 10

Average number of people ride ferry boat = 62.5

Average number of people ride ferry boat = 62 or 63 people

Answer:

What's the key difference between the t- and z-distributions? The standard normal or z-distribution assumes that you know the population standard deviation. The t-distribution is based on the sample standard deviation.

The major difference between a hypothesis test with the t statistic formula and the test with a z‐ score is,

⇒  You must know the population variance (or standard deviation) for the z‐score but not for the t statistic.

Standard deviation is the measure of dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

We have to given that;

To find the major difference between a hypothesis test with the t statistic formula and the test with a z‐ score.

Now, We know that;

The major difference between a hypothesis test with the t statistic formula and the test with a z‐ score is the population variance (or standard deviation) for the z‐score but not for the t statistic.

Thus, The major difference between a hypothesis test with the t statistic formula and the test with a z‐ score is,

⇒  You must know the population variance (or standard deviation) for the z‐score but not for the t statistic.

Answer:

1. 140 degrees

2. 40 degrees

3. 65 degrees

4. 75 degrees

5 115 degrees

Step-by-step explanation:

1. The inside angle adjacent to angle 1 is 40. We know this because a triangle's interior angles have to add up to 180, and the only number when added to 140 (60+80) to equal 180 is 40. That means that 1 has to be the other part to equal 180.

2. The same rule occurs as before. This time angle 1 is 140, and the line they share's angles have to equal 180, so 2 is 40.

3. The same rule occurs as before with the 105 outside the triangle. 40 + X + 75 = 180, which means that 3 is 65.

4. Using the 105 we can deduce that 105 + X = 180.

5. We use the 40, and angle 4 + X to equal 180. Then we use the X to find 5 to be 115.

Sorry if that is confusing. Your book will probably have better explanations that I will.

Answer:

1x 2x 3x

Step-by-step explanation:

Answer:

12 + 1/10x

that would be the expression

Step-by-step explanation:

Answer:

number of 50c = x

number of 20c = y

total coins 40

x +y = 40 ------(1)

0.5x + 0.2y = 16.10 ------(2)

from (1) => x = 40 - y

substitute x in (2)

0.5(40 -y) + 0.2y = 16.10

20 - 0.5y + 0.2y = 16.10

-0.3y = -3.9

y = 13

from (1) => x = 27

Answer: number of 50c = 27 coins

Step-by-step explanation:

You would get the probability of double sixes as:

Correct choice is A

The Robin because there are 36 outcomes and only one is (6, 6) is the correct option.

We have given that,

Robin, Steven, and John are comparing tree diagrams for rolling double sixes on two six-sided number cubes (6, 6).

Robin thinks the probability is 136 based on the tree diagram they created.

Steven disagrees and argues that the probability of rolling double sixes is 16.

John counts twelve outcomes and claims the probability is 112.

The formula to calculate the probability of an event is as follows. Probability(Event) = Favorable Outcomes/Total Outcomes

You would get the probability of double sixes as:

P(6, 6) = 1/6*1/6 = 1/36

Correct choice is A.

Therefore the Robin, because there are 36 outcomes and only one is (6, 6).
