The slope formula is y2-y1/x2-x1, so you plug in you numbers to get -3-6/5+1. This simplified to -9/6, or -3/2
Hello there!
3. The questions asks for the amount of simple interest. The formula for simple interest is prt, where p = principal, r = rate, t = time. In this case, we are talking about 3 of them. 25,000 * 3 is 75,000. Now, let's multiply that number by 3% to find the amount of interest. 75,000 * 3% (0.03) is 2,250. Because this is only for one year, the number remains the same, so we don't have to multiply anything. There. The Branson family earns $2,250 in interest in one year. The answer is C.
4. Okay. For this inequality, we already have it set up. All we have to do is divide each side by 4 to isolate the x. 4x/4 cancels out. 22/4 is 5.5. There. x ≥ 5.5. The answer is B.
5. For this one, she hits the ball 22% of the time. To find out how many hits she will make, all you have to do is multiply the times at bat by 22%. In this case, she's at the bat 50 times. 50 * 22% (0.22) is 11. There. She will get about 11 hits. The answer is A.
You have the ratios set up but you need to cross multiply everything:
(5x + 10) x 11 = 121 x 10
55x + 110 = 1210
Subtract 110 from both sides:
55x = 1100
Divide both sides by 55:
X = 1100 / 55
X = 20
Answer:
The population is all the adult men who are 40 to 60 years of age and live in the United Stades.
Step-by-step explanation:
The population is all the adult men who are 40 to 60 years of age and live in the United Stades.
The 1338 are the sample, and the study wants to find the proportion of all these adults who had seen their family doctor. Since 1338 is a large sample size, this proportion can be extended to all the adult men who are 40 to 60 years of age and live in the United Stades.
