Answer:

1131

Step-by-step explanation:

2900 x .39 = 1131

Answer:

48.9 and 50.5 are rejected.

Step-by-step explanation:

Since the standard deviation shows the spread of the values of the voltages, we need to find the mean of the values and use the standard deviation to find the minimum and maximum voltage allowed.

So mean μ = Σx/N where x = individual values of voltage and N = number of values = 10

So, μ = Σx/N

= (49.3 + 50.1 + 48.9 + 49.2 + 49.7 + 50.5 + 49.9 + 49.3 + 49.8 + 50.2)/10

= 496.9/10

= 49.69

≅ 49.7 V

So, the acceptable values of voltage are in the range μ ± σ where σ = standard deviation = 0.50 V.

So, the acceptable values of voltage are in the range 49.7 ± 0.50 V

So, minimum value = 49.7 V - 0.50 V = 49.2 V

and maximum value = 49.7 V + 0.50 V = 50.2 V

So any voltage outside the range 49.2 V ≤ x ≤ 50.2 V is rejected.

There are two values outside this range which are 48.9 and 50.5. So these two values are rejected.

How to calculate is 600/5

Answer

The average speed of the car is 120 miles per hour.

Explanation

The formula to find speed is distance over time.

600 miles is the distance.

5 hours is the time.

So divide 600 by 5.

600 divided by 5 is 120, meaning the average speed of the car is 120 miles per hour.

Answer:

(x-1)(x+1)(x+3)

Step-by-step explanation:

first you group the 2 parts of the equation

{(x^3) + (3x^3)} {-x - 3}

you can take out x squared from the first group and are left with x+3 and you can take out -1 from the second group also leaving you with x+3. Because these groups match it means that x+3 is a factor.

x^2(x+3) -1(x+3)

combine them

(x^2-1) (x+3)

x squared minus one can be simplified more to (x-1) and (x+1) so the final answer is (x-1)(x+1)(x+3)

Answer:

a) The average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=1 to x=2 is 8

b) The average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=3 to x=4 is 32

Step-by-step explanation:

We are given function [tex]f(x)=4(2)^x[/tex]

We need to find Average rate of change

The formula used is: [tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}[/tex]

Part a) The interval is: x=1 to x=2

We have a= 1 and b=2

Finding f(a) i.e f(1)

[tex]f(x)=4(2)^x\\Put \ x =1\\f(1)=4(2)^1\\f(1)=4(2)\\f(1)=8[/tex]

Now finding f(b) i.e f(2)

[tex]f(x)=4(2)^x\\Put \ x =2\\f(2)=4(2)^2\\f(2)=4(4)\\f(2)=16[/tex]

Now finding average rate of change.

[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{16-8}{2-1} \\Average \ rate \ of \ change=\frac{8}{1}\\Average \ rate \ of \ change=8[/tex]

So, average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=1 to x=2 is 8

Part b)

The interval is: x=3 to x=4

We have a= 3 and b=24

Finding f(a) i.e f(3)

[tex]f(x)=4(2)^x\\Put \ x =3\\f(3)=4(2)^3\\f(3)=4(8)\\f(3)=32[/tex]

Now finding f(b) i.e f(4)

[tex]f(x)=4(2)^x\\Put \ x =4\\f(4)=4(2)^4\\f(4)=4(16)\\f(4)=64[/tex]

Now finding average rate of change.

[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{64-32}{4-3} \\Average \ rate \ of \ change=\frac{32}{1}\\Average \ rate \ of \ change=32[/tex]

So, average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=3 to x=4 is 32

Since the interval is increasing, so does our average rate of change increasing as function is also increasing.

Answer:

1.5 hr

Step-by-step explanation:

The number of hours of practice each day is 1.5 hours.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of practice weeks = 5

Number of practice days in a week = 5

The total number of practice days.

= 5 x 5

= 25 days

Total time for 25 practice days = 37.5 hours.

The number of hours each practice day.

= 37.5 ÷ 25

= 1.5 hours

Thus,

1.5 hours of practice each day.

Answer:

Step-by-step explanation:

-5(y-15=3x) = -5y+75=-15x

add 15x to both sides and subtract 75 to both side

-5y+15x=-75

5y-2x=-3

13x=-78

and then both side divide by 13

x=-6

y-15=3(-6)

y-15=-18

Y= (-18) - 15 =  -3

y=-3

Answer:

Angle a = 112.5°

Angle b = 67.5°

Step-by-step explanation:

Angle a + angle b = 180° (Supplementary Angles/angles on a straight line)

Let x = m<b

m<a = ⁵/3(x)

Therefore:

⁵/3x + x = 180

[tex] \frac{5x}{3} + x = 180 [/tex]

[tex] \frac{5x + 3x}{3} = 180 [/tex]

[tex] \frac{8x}{3} = 180 [/tex]

Multiply both sides by 3

[tex] \frac{8x}{3} \times 3 = 180 \times 3 [/tex]

[tex] 8x = 540 [/tex]

Divide both sides by 8

x = 67.5°

Angle a = ⁵/3(x) = ⁵/3(67.5) = 112.5°

Angle b = x = 67.5°

Answer:C

Step-by-step explanation:

C

Step-by-step explanation:

First, replace f(x) with y ⇒ f(x)=6x-19 ⇒ y=6x-19

Then y with x and x with y  ⇒ y=6x-19 ⇒ x=6y-19

Solve the equation from for y:

           x=6y-19

           x+19=6y dividing with 6

           1/6 x +(19/6) = y

Replace y with f−1(x) ⇒ f−1(x)= 1/6 x +(19/6)
