Answer:
$445.20
Step-by-step explanation:
First, find his pay after the 5% raise:
400(1.05)
= 420
Find his pay after the 6% raise:
420(1.06)
= 445.2
So, his weekly pay is now $445.20
Answer:
50°
Step-by-step explanation:
Answer:
(A) P (D > 0) = 99.38%
(B) P (D > 15) = 10.56%
Step-by-step explanation:
The random variable D = difference, is defined as the difference between the reading test scores after and before the program.
The random variable <em>D </em>follows a normal distribution with mean, and standard deviation, .
(A)
Compute the probability that the children showed any improvement, i.e.
P (D > 0):
Use the standard normal random variable to determine the probability.
The percentage of children showed any improvement is:
0.9938 × 100 = 99.38%
Thus, 99.38% of children showed improvement.
(B)
Compute the probability that the children improved by more than 15 points, i.e. P (D > 15):
Use the standard normal random variable to determine the probability.
The percentage of children improved by more than 15 points is:
0.1056 × 100 = 10.56%
Thus, 10.56% of children showed improvement by more than 15 points.
Answer:
Option (D)
Step-by-step explanation:
In a function y shows the values of the function (Output values) and x shows the (input values).
Therefore, to convert any equation into the function, we will solve the equation for y.
Given equation is,
680x + 10y - 1000 = 0
680x + 10y = 1000
68x + y = 100
y = -68x + 100
Now replace y by f(x).
Therefore, the function will be,
f(x) = -68x + 100
Option (C) will be the correct option.
