Answer:
3 and 3/4 cups of cornstarch
Step-by-step explanation:
5/8 cornstarch = 1/6 cup of water
1/6 x 6 = 1 cup of water so we multiply the 5/8 of cornstarch by 6 on the other side, because what you do to one side you must do to the other.
5/8 * 6/1 = 15/4 or 3 and 3/4 cups of cornstarch is needed (this is also 3.75 in decimals)
6 times 79 = 474 so the 79th term is 474
Answer: the z score is - 5.33
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to the Z-score test result of 1300 points.
For x = 1300,
z = (1300 - 1700)/75 = - 400/75 =
- 5.33
