Answer:
14.5 units
Step-by-step explanation:
we need to find the length of the rectangle. To do that, we must find the hypotenuse of the right triangle below the rectangle.
Finding the hypotenuse of a right triangle uses the Pythagorean theorem, or a² + b² = c²
let a be 9 and b be 7.
9² + 7² = c²
81 + 49 = c²
130 = c²
√130 = c
c = approx. 11.4
Now, we know the length of the rectangle.
Once a rectangle is cut diagonally, it forms 2 equal right triangles. We will use the same process to find the hypotenuse of the second right triangle.
9² + 11.4² = c²
81 + 130 = c²
81 + 130 = approx. 211
c² = 211
√211 = c
c = approx. 14.5
Answer:
The probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb
P(x⁻< 15) = 0.1587
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the size of the sample 'n' =49
Mean of the Population = 17ppb
The standard deviation of the population = 14ppb
Let 'X' be the random variable in a normal distribution
<u><em>Step(ii):</em></u>-
The probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb
P(x⁻< 15) = P(Z<-1) = 1-P(Z>-1)
= 1-(0.5+A(-1))
= 0.5 - A(1)
= 0.5-0.3413
= 0.1587
<u><em>Final answer:-</em></u>
The probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb
P(x⁻< 15) = 0.1587
