Determine the solution to f(x) = g(x) using the following system of equations:f(x) = 5.5x − 13
g(x) = −5x + 18.5

x = 1
x = 2
x = 3
x = 4

Answers

5.5x-13=-5x+18.5 so 10.5x=31.5 so x=3

Answer:

the answer is x = 3

We did not recieve a diagram for this question.Radius of circle O has a slope of 2.5. What is the slope of the line tangent to circle O at point A?

A)0.8
B)2.5
C)-0.4
D)-5

Answers

If the line is tangent to circle at point A and the radius ( suppose AO) has a slope of 2.5 then a slope of the tangent line is :
(-1)/(2.5)= -0.4
Explanation: The product of slopes of two perpendicular lines is -1. To get second slope we have to divide -1 by the first one.
Answer:C) - 0.4

A rental car costs $48 for one day plus an additional $0.52 per mile. If you have $110, how many miles can you drive the car?

Answers

Answer:

2.27 miles is the answer.

Step-by-step explanation:

Money needed = $48+$0.52 = $48.52

So,

$48.52 = 1 mile

$1 = 1/$48.52

$110 = (1/$48.52)×$110

= 2.27 miles

An optical inspection system is used to distinguish among different part types. The probability of a correct classification of any part is 0.94. Suppose that three parts are inspected and that the classifications are independent. Let the random variable X denote the number of parts that are correctly classified.

Answers

Answer:

µ = 2.82

Variance(X) =  0.169

Step-by-step explanation:

The complete question is:

An optical inspection system is to distinguish among different part types. The probability of a correct classification of any part is 0.94. Suppose that three parts are inspected and that the classifications are independent. Let the random variable X denote the number of parts that are correctly classified. Determine:

(a) the mean

(b) variance of X .

Round your answers to three decimal places

Solution:

Part A:

First we have to find the mean.

We have,

n = 3

p = 0.94

µ = n*p

Put the values in the formula:

µ = 3*0.94

µ = 2.82

Part B:

To find the Variance of X:

Var(X) = np(1 - p)

= 2.82(1 - 0.94)

= 2.82(0.06)

= 0.1692

By rounding off:

= 0.169
