Answer:

Wendy = W

Connie = C

Tim = T

Equations

W = C + 4

C = T + 4

W + C + T = 45

Solution

Put W into the third equation

C + 4 + C + T = 45

2C + 4 + T = 45

Put T into the above equation

C = T + 4

T = C - 4

2C + 4 + C - 4 = 45

3C  = 45

C = 15

C = T + 4

15 = T + 4  The answer is: 11 = T

Convert from $0.20 dollars to cents
Arada [10]
Since 100 cents = $1

Then to convert $20 to cents, all you have to do is multiply.

 $20 × 100 cents

<em><u>=2000 cents. </u></em>

More examples to try:

Convert $0.10 dollars to cents.

$10 × 100 cents = 1000 cents.

 

Here is a guild for next time:

100 cents = $1
200 cents = $2
300 cents = $3
400 cents = $4
___ cents = $__

So.....now you can fill in the blanks by yourself. Tell me the answer if possible! :D

Write each equation in slope intercept form x+7y=48
Elan Coil [88]

Answer:

y=-1/7+48/7

Step-by-step explanation:

You want to isolate the Y so you subtract the x to the other side.

Next you divide both numbers on the right hand side by 7 and that gives you

y=-1/7+48/7

Calibrating a scale:
lana66690 [7]

Answer:

We conclude that the calibration point is set too high.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ =  1000 grams

Sample mean, \bar{x} =  1001.1 grams

Sample size, n = 50

Alpha, α = 0.05

Population standard deviation, σ = 2.8 grams

First, we design the null and the alternate hypothesis

H_{0}: \mu = 1000\text{ grams}\\H_A: \mu > 1000\text{ grams}

We use One-tailed(right) z test to perform this hypothesis.

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{ 1001.1 - 1000}{\frac{2.8}{\sqrt{50}} } = 2.778

Now, z_{critical} \text{ at 0.01 level of significance } = 2.326

Since,  

z_{stat} > z_{critical}

We reject the null hypothesis and accept the alternate hypothesis. We accept the alternate hypothesis. We conclude that the calibration point is set too high.
