Answer:

B) 5 hours

Step-by-step explanation:

First, find the amount of mph between 60 and 80:

80 - 60

= 20 mph

Since the speed increases 4 mph per hour, we can find how long it will take to get to 80 mph by dividing 20 by 4:

20/4

= 5

So, the correct answer is B, 5 hours

HELP MEH I can't figure this out. Please explain

vova2212 [387]

Answer:

x ≈ 33.0

Step-by-step explanation:

The third angle in the triangle is

180° - 70° - 76° = 180° - 146° = 34°

Using the Sine rule in the triangle

$\frac{x}{sin76}$ = $\frac{19}{sin34}$ ( cross- multiply )

x × sin34° = 19 × sin76° ( divide both sides by sin34° )

x = $\frac{19sin76}{sin34}$ ≈ 33.0 ( to the nearest tenth )

Step-by-step explanation:

i think both are false.

$\lim_{x \to - \infty} f(x)= \lim_{x \to- \infty} (4x^8-3x^7+2x-11)\\ = \lim_{x \to - \infty} x^8(4-\frac{3}{x}+\frac{2 }{x^7} -\frac{11}{x^8})\\=-\infty(4-0+0-0)\\=-4 \infty\\=- \infty\\similarly other$

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.
