Answer: <u>B, about 280 ounces</u>
16.9 + 15.2 = 32.1
32.1 * 7 = 224.7
Not A because she doesn't drink 30 oz she drinks 32.
B is the closest and is rounding both numbers up.
C is false because you don't multiply by 10, you multiply by 7 because of the 7 days in a week.
D is false for the same reason as C.
Answer: 180 = 30 + (x + 60)
Step-by-step explanation: Supplementary means that the angles add together to 180 degrees. This equations shows that angle A (30 degrees) plus angle B (x + 60) equal 180. If you solve the equation you will find that angle B is equal to 150 degrees, and that x = 90.
Answer:
z = -0.57
Step-by-step explanation:
A z-score indicates how much away is something from the mean so it can be more(above) than the mean or less(below) than the mean.
sampling distribution mean = 0.03
standard error = 0.007
researcher's sample mean = 0.026
z = (0.026 - 0.03)/0.007
z = (-0.004)/0.007
z = -0.57
So that means the researcher's sample mean is 0.57 standard deviation below the sampling distribution mean.
The negative sign above is the indicator of below the mean value.
