Answer:

Step-by-step explanation:

For the first question

The missing term is 30

because 5 is being added to every term .

So last known term is 25 and by the sequence we can see that 5 is being added to the last term to make the next one

25+5=30

For the second: Pay attention

Let's say you want to find the nth term of the sequence. (Eg. what will be the 50th number of the series just like 10 is the 1st term of the sequence)

For nth term the formula is :

An= d.n+a1-d

where d is the difference '5' in this case

n is the nth term

a1 is the first term (10 in your case) and again d is the difference of number which is 5

an=5n+5 (by substituting values)

now for finding 100th term put 100 in place of n

a100=5(100)+5

a100=505

100th term is 505

The 100th term would be 505.

Let’s assume the following statements are true: Historically, 75% of the five-star football recruits in the nation go to univers

marishachu [46]

Given:
75% of the five-star football recruits in the nation go to universities in the three most competitive athletic conferences. → 25% goes to other schools.

five-star recruits get full football scholarships 93% of the time, regardless of which conference they go to. → 7% of the 5-star recruits don't get full football scholarships.

a. The probability that a randomly selected five-star recruit who chooses one of the best three conferences will be offered a full football scholarship?
75% * 93% = 69.75%

b. What are the odds a randomly selected five-star recruit will not select a university from one of the three best conferences?
25% of selected five-star recruit will not select a university from one of the three best conferences. I got the number based on the given data. Since, 75% will go, the remaining percent won't go. Total percentage should be 100% of the population.

c. Explain whether these are independent or dependent events. Are they Inclusive or exclusive?
These are independent events. One can still go to different school and still be legible for the full football scholarship.

For question 2, pls. see attachment.

From a to D which graph represents a function ? And why ?

tatiyna

Option D I believe because it is the only one that passes the vertical line test (the test that for every X value, there is only 1 Y value).

Convert 2500mm2 into m2 How do I do it?

N76 [4]

Step-by-step explanation:

$2500 \: {mm}^{2} \\ \\=2500\: 1\: mm\times 1\: mm\\=2500\times\frac{1} {1000}\:m \times \frac{1} {1000}\:m\\=2500\times\frac{1} {1000\times 1000}\:m^2 \\=2500\times\frac{1} {1000000}\:m^2 \\=2500\times\frac{1} {10^6}\:m^2\\= 2500 \: \times 10^{-6}\: m^2 \\ = 0.0025 \: {m}^{2} \\ \\ \bigg( \because1 \: mm = \frac{1}{1000} \: m \bigg)$
