A. z = 0.74
The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.
b. z = -2.16
This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score
c. z = 1.02
The percentile equivalent of the z-score above is 0.846. The area is also 0.846.
d. z = -0.15
The percentile equivalent and the area is equal to 0.44.
5.50 x 3.87 equals 21.285. 21.285 rounded to the nearest cent is $21 dollars and 3 cents.
To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).
Answer:
= -3
Step-by-step explanation:
Find 2 points
(-2, 4) and (1,-5)
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (-5-4)/(1 - -2)
= -9/(1+2)
= -9/3
= -3
