What is the length of segment CE if AE = 15 inches and ED = 5 inches and EB = 3 inches?

Mathematics

Artemon [7]3 years ago

We have to determine the length of segment CE if AE = 15 inches and ED = 5 inches and EB = 3 inches.

Since ,we can observe that AB and CD are chords intersecting at point E.

Therefore, by intersecting chord theorem which states:

" When two chords intersect each other inside a circle, the products of their segments are equal"

So, AE \times EB= CE \times ED

15 \times 3= CE \times 5

45= CE \times 5

CE = \frac{45}{5}

CE = 9 inches.

So, the measure of segment CE is 9 inches.

So, Option B is the correct answer.

Answer:

B. The experimental probability of a 1 is 25%.

Step-by-step explanation:

Since there are 4 sections of equal size, the theoretical probability of landing on any one of the them is equal. The probability of landing on any one of the sections is 25%. The experimental probability is based on the results of an actual experiment, meaning spinning the spinner, and recording the results.

A. The theoretical probability of a 1 is 25%. True as explained above.

B. The experimental probability of a 1 is 25%. False. There were three spins. One spin resulted in a 1. The experimental probability of spinning a 1 is 1/3 or 33 1/3 %.

C. If you spin the same spinner again and get different results, the experimental probabilities are different, but the theoretical probabilities have not changed. True. See explanation above. The theoretical probability is always 25% for any of the sections, 1, 2, 3, or 4. The experimental probability depends on the results of the actual spins that were performed.

D. The experimental probability of a 2 is 0%. True. The spinner was spun 3 times. There was no result of a 2, so the experimental probability of landing on a 2 is 0%.

Answer: The false statement is B. The experimental probability of a 1 is 25%.

Five numbers have a range of 14. Four of the numbers are 20, 22, 31 and 25. Work out the two different possible values for the f
Pepsi [2]

Answer:

17

34

Step-by-step explanation:

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

the missing number can either by the highest value or the lowest value. this is because none of the numbers given when subtracted from each other would give a value of 14

let x = missing number

14 = x - 20

x = 20 + 14 = 34

or

14 = 31 - x

x = 31 - 14

x = 17

abruzzese [7]

Not sure about the weird echo in the question but I think we're being ask to evaluate

4 - 0.25g + 0.5h

when g=10, h=5

That's

4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4

Which of the following data is used to determine credit scores? A. who stays with you at your current residence B. the location
Crazy boy [7]

Answer:

The length of stay at your current residence is used to determine credit scores. On most credit applications and applications in general, this question is asked to help the lender look up information about your history of payments. When a lender asks this question they are able to determine how long you typically stay in one place, and look up bills at that residence to make sure they are paid on time before giving out a loan. They can also use this information to determine a credit score based on what is being paid on time, late or not at all.

Stephen evaluated (6.34 times 10 Superscript negative 7 Baseline) (4.5 times 10 Superscript 3 Baseline). His work is shown below
Maksim231197 [3]

Answer:

The step 4 and 5 describe the errors Stephen made.

Step-by-step explanation:

Given : Stephen evaluated (6.34\times 10^{-7})(4.5\times 10^3).  His work is shown below.

To find : Which two statements describe the errors Stephen made?

Solution :

Step 1 - (6.34\times 10^{-7})(4.5\times 10^3)

Step 2 - (6.34\times 4.5)(10^{-7}\times 10^3)

Step 3 - (28.53)(10^{-4})

Step 4 - 28.53\times 10^{4}

Error is the step as 4 sign is negative.

So correct step is 28.53\times 10^{-4}

Step 5 - 28.53\times 10^{3}

Error is the step as there is 4 in place of 3.

So correct step is 28.53\times 10^{-4}

The step 4 and 5 describe the errors Stephen made.
