Ernesto guesses there are 69 marbles in a jar, but there are actually 60.

What is the percent error in Ernesto's guess?

Answers

Answer:

15%

Step-by-step explanation:

Since the problem is to find how much 69 is as a percent if 60 is 100%, we can use a rule of three, simple, direct proportion to do it:

60 = 100%

68 = x

x = 69x100/60

x = 115

That means 69 is 115% of 60, which means that the error is of:

115 - 100 = 15%

Suppose our student center published data that the average starting salary for college graduates is 59k. You randomly sampled 49 college graduates and calculated the sample average salary is 44k. What test can you use to check whether the true average is 59k?.

Answers

To check whether the true average is 59k or not, A sample mean T-Test needs to be conducted.

What is an Average?

In the field of statistics, average means that the ratio of the sum of the numbers of a given set, to the total number of characters in a given set. It is also called as the Arithmetic mean.

It is given that the student center has published the data that the average salary of the college graduates is 59k. Accordingly, the sample of 49 college students were verified and the sample average salary came out to be 44k.

When we analyze the  given question, we find that,

The total number of students were 49,

The true average was found to be 59k,

and the Sample average is found to be 44k.

Thus, in  the present question we will use the One- sample T-test.

You spin the spinner and flip a coin. Find the probability of the compound event.

The spinner is divided into 5 equal regions with numbers 1,2,3,4,and 5

The probability of spinning an even number and flipping heads is

Answers

The probability of spinning an even number and flipping heads is 1/5

How to determine the probability?

The sections on the spinner are given as

Sample space (sections) = {1, 2, 3, 4, 5}

These sections mean that

P(Even number) = Count of even numbers/Number of sections

So, we have the following representation

P(Even number) = 2/5

Also, we have

Coin = {H, T}

This means that

P(Head) = 1/2

So, we have the probability equation

P(Even and Head) = P(Even) * P(Head)

This gives

P(Even and Head) = 2/5 * 1/2

Evaluate

P(Even and Head) = 1/5

So, the probability is 1/5

What are the properties of similar triangles?

In Geometry, two (2) triangles are similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.

Additionally, two (2) geometric figures are considered to be congruent only when their corresponding side lengths are congruent and the magnitude of their angles are congruent.

Now, we can write an equation that can be used to determine the tree's height. Since the ratio of the corresponding sides of similar triangles are equal in magnitude, we have the following mathematical expression (equation):

22.5/8.25 = x/5.5

Where:

x represents the height of the tree.

How tall is the tree?

22.5/8.25 = x/5.5

Cross-multiplying, we have:

8.25x = 22.5 × 5.5

8.25x = 123.75

x = 123.75/8.25

x = 15 feet.

How far is the person standing from the tree?

The distance of this person from the tree can be calculated as follows;

The minimal weight of the center 95% of the members is

P(X > 95) = P((95 - 200) ÷ 25) < (X - µ) ÷ σ)

Answers

Answer:

perpendicular

Step-by-step explanation:

Find the slope for both lines and compare. Same slope would mean parallel. Different slopes means intersecting lines. But specifically if the slopes are opposite sign and reciprocals (one is flipped over from the other) then they are perpendicular.

Put them in slope-intercept form to find the slope.

y = mx + b

m is the slope (number by the x)

y = 3(x+7)

distribute the 3.

y = 3x + 21

This line has a slope of 3.

y + 5 = -1/3 x

y = -1/3 x - 5

This line has a slope of -1/3.

-1/3 and 3 are negative reciprocals. They have opposite signs. Also 1/3 is just 3 but flipped over. They are perpendicular.
