miskamm [114]

Answer:

75 chairs

Step-by-step explanation:

1. 9x+3 : write equation

2. 7x+19 : write equation

3. 9x+3=7x+19 : make both equations equal to each other

4. 2x+3=19 : subtract 7x from both sides

5. 2x=16 : subtract 3 from both sides

6. 8 : divide 2 on both sides of the equal sign

7. 9(8)+3=75 : plug 8 into the equation

Anton [14]

Answer:

yes, the meal costs 25.60

Step-by-step explanation:

I used a slightly different method but B (Yes. They have enough to pay their bill: 21 dollars times 1.06 = 22 dollars and 26 cents and 22 dollars and 26 cents times 1.15 = 25 dollars and 60 cents.) is correct.

21*0.06=1.26

1.26+21=22.26

22.26*0.15=3.34

22.26+3.34=25.60

normal population has a mean of 63 and a standard deviation of 13. You select a random sample of 25. Compute the probability tha
alexira [117]

Answer:

0.2207

Step-by-step explanation:

Here, we want to find the probability that the sample mean is greater than 25.

What we use here is the z-scores statistic

Mathematically;

z-score = (x-mean)/SD/√n

From the question;

x = 65, mean = 63, SD = 13 and n = 25

Plugging these values in the z-score equation, we have

Z-score = (65-63)/13/√25 = 2/13/5 = 0.77

So the probability we want to calculate is ;

P(z > 0.77)

This can be obtained from the standard normal distribution table

Thus;

P(z > 0.77) = 0.22065 which is 0.2207 to 4 d.p
