Answer:

Expression  Katrina drinks of water in 7 day = 8 *7 cups .

Step-by-step explanation:

Given  : Katrina drinks 0.5 gallons of water per day and There are 16 cups in a gallon.

To find : Which expression shows how to find the number of cups of water she drinks in a week.

Solution : We have given that

Katrina drinks of water per day = 0.5 galoons.

1 gallon  = 16 cup .

So,  Katrina drinks of water per day = 0.5 * 16 cups.

Katrina drinks of water per day = 8  cups.

1 week =  7 days .

Katrina drinks of water in 7 day = 8 *7 cups.

Katrina drinks of water in 7 day = 56  cups.

Therefore, Expression  Katrina drinks of water in 7 day = 8 *7 cups .

Answer:

The correct option is;

c. Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.

Step-by-step explanation:

Here we have the values

μ = 275 mL

275.4

276.8

273.9

275

275.8

275.9

276.1

Sum = 1928.9

Mean (Average), = 275.5571429

Standard deviation, s = 0.921696159

We put the null hypothesis as H₀: μ₁ = μ₂

Therefore, the alternative becomes Hₐ: μ₁ ≠ μ₂

The t-test formula is as follows;

t=\frac{\bar{x}-\mu }{\frac{s}{\sqrt{n}}}

Plugging in the values, we have,

Test statistic = 1.599292

t_{\alpha /2} at 7 - 1 degrees of freedom and α = 0.05 = ±2.446912

Our p-value from the the test statistic = 0.1608723≈ 0.1609

Therefore since the p-value = 0.1609 > α = 0.05, we fail to reject our null hypothesis, hence the evidence suggests that the mean does not differ from 275 mL.

Okay well I do it like this. 3+8=11. I put a 1 down and carry the other. so I do 7+0+1=8 so now I have 81, and last I do 6+3=9. so the answer would be 981.
