The side length of a square is x+1. write an expression that is equivalent to the perimeter of the square.

1 answer:

4 0

4x + 4

This is because there are four sides of a square, and each side is x + 1.

x + 1 + x + 1 + x +1 + x + 1 = 4x + 4

Travka [436]

Answer:

The graph that has the points (2,4) and (4,8) should be the answer.

Step-by-step explanation:

This is the answer because if you see the ratio 2:4, that means that for every 2 offense cards there are 4 defense cards. As you continue to go up it would be (4,8), (6,12), (8,16), and so forth.

Suppose the scores on a test given to all juniors in a school district are normally distributed with a mean of 74 and a standard

ivann1987 [24]

Answer:

$\mu -\sigma = 66 , \mu +\sigma = 82$

$\mu -2\sigma = 58 , \mu +2\sigma = 90$

$\mu -3\sigma = 50 , \mu +3\sigma = 98$

And in the figure attached we see the limits with the percentages associated.

Step-by-step explanation:

For this case we know that the random variable of interest is the scores on a test given to all juniors in a school district follows a normal distribution with the following parameters:

$X \sim N(\mu= 74, \sigma =8)$

For this case we know from the empirical rule that within one deviation from the mean we have approximately 68.2% of the data, within 2 deviations from the mean we have 95% and within 3 deviation 99.7%

We can find the limits and we got:

$\mu -\sigma = 66 , \mu +\sigma = 82$

$\mu -2\sigma = 58 , \mu +2\sigma = 90$

$\mu -3\sigma = 50 , \mu +3\sigma = 98$

And in the figure attached we see the limits with the percentages associated.

The temperature dropped 18 degrees from 6:00 P.M. to midnight. If the temperature at midnight was 2°F, what

vazorg [7]

Answer:

x - 18°F = 2°F

x = 20°F

Step-by-step explanation:

First, write the equation with the information you know. It dropped 18°F from 6 to midnight, and by midnight the temperature was 2°F

Your equation should look like this: x - 18°F = 2°F

Move the constant to the right hand side and change it's sign:

x = 2°F + 18°F

Add the numbers to get x = 20°F

Hope this helped!

Answer:

Linear Equation: y=-44000x+88922000

Year 2009: $526000

By year 2021, they have no more fund

Step-by-step explanation:

Slope formula is difference of y/difference of x. 79000-70200/2003-2005=

-88000/2=-44000.

To find the y intercept, x=0.

It should be year 0. 44000x2003=88132000+790000=88922000

Now put it into y=mx+b

y=-44000x+88922000

Plug in 2009.

It should equal 526000.
