sand. In all, Jack put 2 pounds of sand in bags. Cheryl bought 14 pounds of oranges and apples. She bought 7 pounds of oranges and 2 pounds of apples. Kate had 14 muffins. She put an equal number of muffins in 7 boxes. So, Kate put 2 muffins in each box.

Kate's situation is correct because she put 2 muffins each in 7 boxes, which is saying 7 x 2. If you multiply these factors together, you will get 14 muffins; which is the amount that Kate started with.

A data set includes 108 body temperatures of healthy adult humans having a mean of 98.3degrees°F and a standard deviation of 0.6
mylen [45]
<h2>Answer with explanation:</h2>

The confidence interval for population mean is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n=106

Sample mean : \overline{x}=98.3^{\circ}\ F

Standard deviation : \sigma= 0.69^{\circ}F

Significance level : \alpha: 1-0.99=0.01

Critical value : z_{\alpha/2}=2.576

Then , 99​% confidence interval estimate of the mean body temperature of all healthy humans will be :-

98.3\pm (2.576)\dfrac{0.69}{\sqrt{106}}\\\\\approx98.3\pm0.173=(98.3-0.173,\ 98.3+0.173)=(98.127,\ 98.473)

Since 98.6 is higher than the upper limit of the confidence interval (98.473), then this suggest that the mean body temperature could be lower then 98.6 degrees.

The best estimate of population mean is always the sample mean. \mu=\overline{x}=98.3^{\circ}\ F

The solution to this puzzle is 10+3 = 13

<h3>How to solve the puzzle</h3>

To solve this the values at the top of the star were gotten by the addition of two values inside the stars.

  • 3 + 12 = 15
  • 12 + 4 = 16
  • 4 + 2 = 6
  • 2 + 10 = 12
  • 10 + 3 = 13

Therefore the answer to this question is 13.

Another way of getting the value is by adding 15 + 16 = 31

12 + 6 = 18

31-18 = 13

Answer: p = 75 + 250

Equation of the situation, in slope-intercept form is given as .

Where,

b = y-intercept

m = slope

n = number of computers sold

p = total cost

All we need to find is the value of m and b.

Using two pairs from the table of values, (4, 550) and (6, 700):

Substitute n = 4, p = 550, and m = 75 in , and find the value of b.

Subtract 300 from each side

b = 250

Substitute m = 75, and b = 250 in

✅Equation that represents the situation would be:
