To make a line y has to equal something

They give us a equation y - 3x = 2

y = 3x + 2

Then we use the given values of x to find y

when x = -2

y = 3(-2) + 2
y = -6 + 2
y + -4

when x = -1 

y = 3(-1) + 2
y = -3 + 2

y = -1

When x = 0

y = 3(0) + 2
y = 0+2
y = 2

When x = 1

y = 3(1) + 2
y = 3 + 2
y=5

Analyze tables use the table that shows the percents of blood types of 145 donors during a recent blood drive
Alenkinab [10]

Answer:

a. 16

b. 80

c. Blood type AB

Step-by-step explanation:

Given:

O = 45%

A = 40%

B = 11%

AB = 4%

Total number of donors = 145

a. No. of donors that had type B blood = \frac{11}{100}*145 = \frac{1,595}{100} = 15.95

Type B blood donors ≈ 16

b. No. of blood donors without blood type O = \frac{40 + 11 + 4}{100}*145 = \frac{55}{100}*145 = \frac{7,975}{100} = 79.75

Those without blood type O ≈ 80

c. Find the number of people that had type AB:

Type AB = \frac{4}{100}*145 = 5.8 ≈ 6. This is less than 10 donors.

Therefore, blood type AB had less than 10 donors.

For 100​ births, P(exactly ​girls) and ​P( or more ​girls). Is girls in 100 births a significantly high number of​ girls? Which
madreJ [45]

Answer;

The relevant probability is 0.136 so the value of 56 girls in 100 births is not a significantly high number of girls because the relevant probability is greater than 0.05

Step-by-step explanation:

The complete question is as follows;

For 100 births, P(exactly 56 girls = 0.0390 and P 56 or more girls = 0.136. Is 56 girls in 100 births a significantly high number of girls? Which probability is relevant to answering that question? Consider a number of girls to be significantly high if the appropriate probability is 0.05 or less V so 56 girls in 100 birthsa significantly high number of girls because the relevant probability is The relevant probability is 0.05

Solution is as follows;

Here. we want to know which of the probabilities is relevant to answering the question and also if 56 out of a total of 100 is sufficient enough to provide answer to the question.

Now, to answer this question, it would be best to reach a conclusion or let’s say draw a conclusion from the given information.

The relevant probability is 0.136 so the value of 56 girls in 100 births is not a significantly high number of girls because the relevant probability is greater than 0.05
