To evaluate this expression you just have to substitue the value that is given.

so since we know m=2 x=7 y=5

and the expression is given mx-y

plug these values in as 2(7)-5 = 14-5 = 9

Answer:

The value of the expression for m=2, x=7, and y=5 is 9.

Step-by-step explanation:

Consider the provided expression.

mx-y

We need to find the value of the expression, for m=2, x=7, and y=5.

Substitute the respective values in the above expression as shown:

(2)(7)-(5)

14-(5)

14-5

9

Hence, the value of the expression for m=2, x=7, and y=5 is 9.

Suppose the weekly amount of money spent on maintenance and repairs by a company is NOT approximately normally distributed. Howe
UNO [17]

Answer:

Probability = 0.00621

Step-by-step explanation:

We are given;

Population mean; μ = 400

Population standard deviation; σ = 20

Raw score; x¯ = 450

the probability that the actual costs will exceed the budgeted amount will be the p-value.

Thus, let's first find the z-score after which we will find the p-value.

z = (x¯ - μ)/σ

z = (450 - 400)/20

z = 50/20

z = 2.5

From online p-value from z-score calculator attached, using z = 2.5; one tailed hypothesis; significance level of 0.05, we have;

P-value = 0.00621

Find the value of B - A if the graph of Ax + By = 3 passes through the point (-7,2), and is parallel to the graph of x + 3y = -5
Gnoma [55]

The required simplified value of B - A = -6.

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Since, line Ax + By = 3 and x + 3y = -5 are parallel than slope of both the line will be same,
m = -1/3 = -A/B
From above
A = B/3  - - - - -(1)


Now line Ax + By = 3 passed through the point (-7, 2). So,
-7A + 2B = 3
from equation 1
-7B/3 + 2B = 3
-B/3 = 3
B = -9
Now put B in equation 1
A = -9 / 3
A = -3

Here,
B - A = -9 + 3 = -6

Thus, the required simplified value of B - A = -6.
