Answer:

y = -3x + 4

Step-by-step explanation:

sorry im late

but all you have to do is isolate the y

so to do that we have to get rid of the 3x

3x + y = 4

in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y

3x + y = 4

-3x -3x

y = -3x + 4

and now y is isolated

Mika is a local farmer who is interested in how often residents in her town go to a farmer's market each month. She surveys 124

TEA [102]

Answer:

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Step-by-step explanation:

Margin of error

$M = z\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation and n is the size of the sample.

Standard deviation of 1.3

This means that $\sigma = 1.3$

She surveys 124 families

This means that $n = 124$

Margin of error and meaning:

$M = z\frac{\sigma}{\sqrt{n}}$

$M = 2.58\frac{1.3}{\sqrt{124}}$

$M = 0.3012$

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

I WILL MARK AS BRAINLIEST! Solve the following

deff fn [24]

Answer:

a. x=35

b. x=4

c. x=30

Step-by-step explanation:

6a) 7/9=x/45

7/9×45=x

7×45/9=x

315/9=x

35=x

x=35

————————

b. 10/8=5/x

5/4=5/x

5/4x=5(the x is in the middle of the division sign here)

5x/4=5(the x is NOT in the middle of the division sign)

5x=5×4

5x=20

x=20/5

x=4

———————

c. x/34=15/17

x=15/17×34

x=15×34/17

x=510/17

x=30

hope that helped you. I can't answer number 7, I'm sorry

At a toy factory, toy cars are produced on an assembly line. It takes 8.216 seconds to attach the wheels. It takes 3.652 seconds

AlexFokin [52]

From what I think;

8.216secs - 1 wheel; 3.652- 1 hood
for I toy car with a wheel and hood the total time is 8.216+ 3.652 = 11.868secs
let x secs be the total time taken to put a wheel and hood for 42 cars
x secs = 42 cars × the total time for one car
x secs = 42× 11.868
x secs= 498.456 secs
