Answer:

b. y = -3x/2 + 2

Step-by-step explanation:

To get 3x + 2y = 4 into slope intercept form:

3x + 2y = 4 (starting equation)

2y = -3x +4 (do the inverse of 3x to get it on the other side)

y = -3x/2 + 2 (divide all of previous equation by 2 to distinguish y)

Answer:

g(3) = -3

Step-by-step explanation:

Step 1: Define

g(x) = -2x + 3

g(3) is x = 3

Step 2: Substitute and Evaluate

g(3) = -2(3) + 3

g(3) = -6 + 3

g(3) = -3

Answer:

g(3) = - 3

Step-by-step explanation:

To evaluate g(3) substitute x = 3 into g(3), that is

g(3) = - 2(3) + 3 = - 6 + 3 = - 3

Answer:

The margin of error reduces to half of it original size

Step-by-step explanation:

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

Let assume the standard deviation is  [tex]\sigma = 0.4[/tex]

When sample size is  n  = 25

       [tex]E = 1.96 *  \frac{0.4 }{\sqrt{25} }[/tex]

        [tex]E =0.1568[/tex]

When sample size is  n  = 100

       [tex]E_1 = 1.96 *  \frac{0.4 }{\sqrt{100} }[/tex]

        [tex]E_1 = 0.0784 [/tex]        

So

     [tex]\frac{E_1}{E} = \frac{0.0784}{0.1568} = \frac{1}{2}[/tex]

Hence the margin of error reduces to half of it original size

Answer:

9/2

Step-by-step explanation:

Answer:

The answer is

[tex] \huge \frac{9}{2} \\ [/tex]

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]

From the question we have

[tex]m = \frac{ - 4 - 5}{0 - 2} = \frac{ - 9}{ - 2} = \frac{9}{2} \\ [/tex]

We have the final answer as

[tex] \frac{9}{2} \\ [/tex]

The required number line that shows the solution of the given expression is the line that has blue points on numbers x = 4 and x = 6. Option B is correct.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

here,
In the question, 4 number line given with a number of point marked in blue representing the solution of the expression |x - 5| = 1, we have to determine the number which shows the correct solution of the given expression,

so,

Simplifying the given expression,
|x - 5| = 1

Since when we Un-mode the expression implement the ± on the other side.
x - 5 = ± 1

Case 1, taking (+)
x - 5 = 1
x = 6

Cae 2, taking (-),
x - 5 = -1
x = -1 + 5
x = 4

Thus, the required number line that shows the solution of the given expression is the line that has blue points on numbers x = 4 and x = 6.

Answer:

The value is  [tex]P( \= X \ge 99) = 0.69146[/tex]

Step-by-step explanation:

From the question we are told that

    The  mean is  [tex]\mu = 100[/tex]

     The standard deviation is  [tex]\sigma = 10[/tex]

       The  sample size is  n  =  25

The standard deviation of the sampling distribution is  

        [tex]\sigma_{\= x} = \frac{\sigma}{\sqrt{n} }[/tex]

=>      [tex]\sigma_{\= x} = \frac{10}{\sqrt{25} }[/tex]

=>      [tex]\sigma_{\= x} = \frac{10}{5 }[/tex]

=>      [tex]\sigma_{\= x} = 2[/tex]

Generally the probability of randomly sampling and finding a sample mean of 99 or more is mathematically represented as

        [tex]P( \= X \ge 99) = 1 - P(\= X < 99)[/tex]

Here  

       [tex]P(\= X < 99) = P(\frac{\= X - \mu }{\sigma } < \frac{99 - 100 }{2} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

=>     [tex]P(\= X < 99) = P(Z < -0.5 )[/tex]

From the z table probability of  (Z <  -0.5  ) is  

     [tex]P(Z < -0.5 ) = 0.30854[/tex]

Generally  

      [tex]P( \= X \ge 99) = 1 - 0.30854[/tex]

=>    [tex]P( \= X \ge 99) = 0.69146[/tex]

Answer:

The term used for the same variable raised to the same exponent is called Like terms.

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6.

Given that, What are terms with the same variable raised to the same exponent

Like terms are the terms that contain the same variables raised to the same power, the coefficients need not be the same. For example, 7x and 2x are like terms because both terms contain the same variable "x"

Hence, The term used for the same variable raised to the same exponent is called Like terms.

Step-by-step explanation:

Given that:

Assembly requires a 4 step process:

Probability distribution of defect :

P(step 1) = 0.1

P(step 2) = 0.2

P(step 3) = 0.08

P(step 4) = 0.05

Firstly, we find the probability that there is no defect in each of the assembly process :

Probability of no defect: = (1 - p(defect))

P(step 1) = 1 - 0.1 = 0.9

P(step 2) = 1 - 0.2 = 0.8

P(step 3) = 1 - 0.08 = 0.92

P(step 4) = 1 - 0.05 = 0.95

Hence,

P(no_defect) = 0.9 * 0.8 * 0.92 * 0.95 = 0.62928

Probability of having a defective component ;

P(defect) = P(no_defect)' = 1 - p(no-defect)

1 - 0.62928 = 0.37072

0.37072

= 0.371

Answer:

4°F

Step-by-step explanation:

If the temperature fell 36°F in 9 hours, then;

36°F= 9hours

to get the change in temperature in 1 hour, we will say;

x°F = 1 hr

Since we have

36°F= 9hours

x°F = 1 hr

Cross multiply

9x = 1*36

9x = 36

x = 36/9

x = 4°F

Hence the change in temperature each hour is at 4°F

Answer:

Given: total of 810 miles

             Judy's miles = x

             Susan's miles = 2x

   Solution:  

Solve for Judy's miles

                            2x + x = 810 miles

                            3x = 810 miles

                            (transpose) x= 810 miles / 3

                            x = 270 (Judy drove 270 miles)

Solve for Susan's miles

                           2x = Susan's miles

                           2(270 miles) = 540 miles

  Answer:  Susan drove for 540 miles

Answer:

Given: total of 810 miles

2x + x = 810 miles

3x = 810 miles

 (transpose) x= 810 miles / 3
