the uniform distribution over the interval 8.5 to 11.5 gallons per minute. Find the probability that between 9.0 gallons and 10.0 gallons are pumped during a randomly selected minute.

Answers

Answer: 1/3

Step-by-step explanation:

Here is the complete question:

machine is set to pump cleanser into a process at the rate of 9 gallons per minute. Upon inspection, it is learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 8.5 to 11.5 gallons per minute. Find the probability that between 9.0 gallons and 10.0 gallons are pumped during a randomly selected minute.

The Probability of the above question will be calculated as:

= (10-9) / (11.5 - 8.5)

= 1/3

The above is the easier way to solve this

what is the equation of the line that has a slope of 5 and passes through the point (2,7)?

Answers

Answer:

[tex]y = 5x - 3[/tex]

Step-by-step explanation:

Given

[tex]Slope, m = 5[/tex]

[tex](x_1,y_1) = (2,7)[/tex]

Required

Determine the line equation

Using slope intercept form, the line equation can be calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

Substitute values for m, x1 and y1. The equation becomes

[tex]y - 7=5(x - 2)[/tex]

Open Bracket

[tex]y-7 = 5x - 10[/tex]

Add 7 to both sides

[tex]y-7+7 = 5x - 10+7[/tex]

[tex]y = 5x - 3[/tex]

Hence, the line equation is: [tex]y = 5x - 3[/tex]

Mr. Logan spent 14 cents at the hardware store buying nails and screws. Nails cost 2 cents, and screws cost 1 cent. If Mr. Logan bought exactly 9 items, how many of each did he buy?


Please help me fast !!!

Answers

Answer:

5 nails and 4 screws

Step-by-step explanation:

Make it into an expression where N= amount of nails bought and S= amount of screws bought. Then set it equal to the amount he paid.

ie: 2n+1s=14

Now make another equation for how many he bought.\

ie: n+s=9

Now subtract one of the letter variables from the second equation to get one on alone.

ie: n=9-s

Now, since you have a value for N, substitute it for the value in the original equation so that there's only one variable.

ie: 2(9-s)+1s=14

Now solve for S.

ie: 18-2s+s=14

ie: -s=-4

ie: s=4

Now you have a number value for S that you can plug in the original equation to find the value of N.

ie: 2n+4=14

ie: 2n=10

ie: n=5

Now plug in your values for N and S into the original equation to check it. Your answer is 5 nails and 4 screws.

If f(x)= x^2-2x+3, find the value of f (-2) and f(3)

Answers

Step-by-step explanation:

Given

f(x) = x² - 2x + 3

Now

f(-2) = (-2)² - 2 * ( -2 ) + 3

= 4 + 4 + 3

= 11

f(3) = 3² - 2 * 3 + 3

= 9 - 6 + 3

= 12 - 6

= 6

Step-by-step explanation:

a family wants to rent a car to go on vacation. Company A charges $30.50 and 9 cents per mile. Company B charges $70.50 and 14 cents per mile. How much more does Company B charge for x miles than company A?
For x miles, Company B charges __ dollars more than company A.

Answers

Answer:

$(39.24x)

Step-by-step explanation:

We need to find out their difference for one mile before calculating their difference for x miles.

Difference per mile = ($70.50 + $0.14) - ($30.50 + $0.90)

                                = $70.64 - $31.40

                                = $39.24

Difference for x miles = $39.24 × x miles

                                    = $(39.24x)
