In this problem, the shape of the sail is equilateral
triangle. You are given that the measurement of each side is x – 10 units. The perimeter
is 63 units. You have to formulate an equation to find the value of x. The
formula of the perimeter is to get the sum of the measurements of the three
sides of the triangle.
x – 10 + x – 10 + x – 10 = 63
3x – 30 = 63
3x = 63 + 30
3x = 93
x = 31
Therefore, the value of x is 31 and the measurement of each
sides is 21 units.

Answer:
1a the square root of 37
1b the same as a
2 y=3x+2
Step-by-step explanation:
a and b use the distance formula
for number 2 use rise over run to find the slope and find where the line intersects to find the y intercept.
Hope this helps :)
Answer:
The probability is 12.66%.
This is a low probability, so it is unlikely for such a combined sample to test positive.
Step-by-step explanation:
If the probability of being infected is 0.005, the probability of not being infected is 0.995.
Then, to find the probability of at least one of the 27 people being infected P(A), we can find the complementary case: all people are not infected: P(A').


Then we can find P(A) using:



This is a low probability, so it is unlikely for such a combined sample to test positive.
