Easy,

write the coordinates out in pairs:

x= hours
y= earnings

(1,10)
(2,20)
(3,30)
(4,40)
(5,50)

Now it makes it much easier to see the increase,

After 1 hour of working she has made $10
After 2 hours of working she has made $20
<span>After 3 hours of working she has made $30
</span>
And so on,

that being said it's easily seen that she is getting paid $10

Thus the unit rate is $10.

What is 100 percent of 158
Mashcka [7]

Answer:

It's 63.29

Step-by-step explanation:

Step 1: We make the assumption that 158 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100%=158.

Step 4: In the same vein, x%=100.

Step 5: This gives us a pair of simple equations:

100%=158(1).

x%=100(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100%/x% = 158/100

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100% = 100/158

x= 63.29%

Therefore, 100 is 63.29% of 158.

Using data from a study, we find a significant difference in the proportion of fruit flies surviving after 13 days between those
mestny [16]

The hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.

<h3>How to illustrate the information?</h3>

The following can be deduced from the information:

x1 = 275

x2 = 170

n1 = 500

n2 = 500

The sample proportion will be:

p1 = 275/500 = 0.55

p2 = 170/500 = 0.34

The pooled proportion will be:

= (275 + 170)/(500 + 500)

= 0.44

The test statistic is 6.681. It should be noted that the test statistics is a number that's calculated by a statistical test. It shows how the observed data are far from the null hypothesis.

The p value in this scenario is extremely small. The p value is a measurement used to validate a hypothesis against the observed data. Therefore, we have to reject the null hypothesis.

In this case, the hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.
