The answer would be A. To find how much 25% of the original price is you have to do .25 multiplied by the price. Then you subtract the answer from the original price.
p - .25p

Answer:
The three angles of the right-angled triangle are
a = 35°
b = 90°
c = 55°
Step-by-step explanation:
We are given the ratio of angles of a right-angled triangle
a:b:c = 7:18:11
Recall that the sum of interior angles in a right-angled triangle is always 180°
7x + 18x + 11x = 180
36x = 180
x = 180/36
x = 5
a:b:c = 7x:18x:11x
a:b:c = 7(5):18(5):11(5)
a:b:c = 35:90:55
a = 35°
b = 90°
c = 55°
Alternatively:
We are given that the smallest angle is 35°
a = 7x = 35
x = 35/7
x = 5
b = 18x
b = 18(5)
b = 90°
c = 11x
c = 11(5)
c = 55°
Answer:
Interior = 60°
Exterior = 120°
Step-by-step explanation:
A triangle has 180° in total.
We have 2 angles, 70 and 50
70 + 50 = 120
For Angle U, we do 180-120 = 60
So the interior angle is 60°
A line is straight and is 180°
With angle U being 60°, and being on a straight line, 180-60 = 120
So exterior angle is 120°
Answer:
0.5996 is the probability that none contain high levels of contamination.
Step-by-step explanation:
We are given the following information:
We treat lab specimen containing high levels of contamination as a success.
P( lab specimen containing high levels of contamination) = 0.12
Then the number of lab specimens follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 4
We have to find the probability that none of the lab specimen consist of high level of contamination.
We have to evaluate:
0.5996 is the probability that none contain high levels of contamination.
