Simple interest, I = 101.40
Time, t = 6 years
interest, i = 1.3%

Interest, I=Pit, rearrange
Principal, P=I/(it)=101.40/(6*0.013)=1300

Someone pls help me!!! Will give brainliest! A survey of 1000 students found that 41% of the surveyed students were freshmen, 31
Korvikt [17]

Answer:

<em>(A) 560 students</em>

<em>(B) P = 0.41</em>

Step-by-step explanation:

<em>(Please check the attached picture for more details)</em>

As given, a survey of 1000 students found that:

41% of the surveyed students were freshmen

=> 1000 x 41/100 = 410 surveyed students were freshmen

31% were juniors

=> 1000 x 31/100 = 310 surveyed students were junior

67% of surveyed students lived on the college campus

=> 1000 x 67/100 = 670 surveyed students lived on the campus

<em>(A) 260 of the surveyed students were freshmen living on the campus</em>

=> A = 410 - 260 = 150 surveyed students were freshmen NOT living on the campus

=> B = 670 - 260 = 410 surveyed students were not freshmen living on the campus

=> The number of surveyed students who were either freshmen or living on the campus:

N = A + B = 150 + 410 = 560

<em>(B)  From a previous survey you know that of interviewed juniors, only 23% live on campus (we don't really need this)</em>

=>The probability a surveyed student is a junior or someone that lives on campus: P = (670 - 260)/1000 = 0.41

I hope this helps!

Find the area of the following figure:
stellarik [79]

Answer:

12m

Step-by-step explanation:

You can break this shape down into a square and a trapezoid. Frist you can find the area of the square by multiplying 2 by 5 to get 10. Then you would find the area of a trapezoid by doing Area = 1/2height(base1+base2). We can find the height by subtracting 5 from 9. (We do this because we know the side of the square is 5m) Therefore the height would be 4m. We know the bases are 2 and 4. From there you can plug those numbers in to the formula. Area=1/2 * 4 (2 + 4)

Area= 1/2 * 4 (6)

Area = 2(6)

Area = 12m
