Answer:
-1/4
Step-by-step explanation:
A reciprocal is simply defined as the inverse of a value or a number. So if we have a fraction of - 4/1 we can just flip the numerator and the denominator to get -1/4.
Answer:
225
Step-by-step explanation:
Well, we already know how many square inches each card is. 18. All we need to do is multiply that number by 150 because we need to make 150 cards. So:
18 x 150 = 2,700inches.
Now all we need to do is divide the number of inches by the amount each foot is. Each foot is 12 inches. So:
2,700 ÷ 12 = 225.
225 is your answer.

So first we see if increase or decrease
180<210
it is increase
then we assume that
percent change
find how much change took place
210-180=30
30/180=x% change
percent means parts out ofo 100s so x%=x/100
30/180=x/100
multiply both sides by 100
3000/180=x
16.66666=x
answe ris 16.6%
A. The empirical rule tells you that 68% of observations fall within one standard deviation of the mean for a normal distribution. [32, 38] = 35 ±3, so your interval is within one standard deviation of the mean.
68% of observations will fall between 32 and 38
B. The distribution is symmetrical about the mean, so half of the observations in part A will be below the mean.
34% of observations will fall between 32 and 35
C. The distribution is symmetrical about the mean, so half the observations fall above the mean.
50% of observations will fall above 35
D. The distribution is symmetrical about the mean, so half the observations will fall below the mean, 35. As in part B, 34% will fall between the mean and one standard deviation above the mean, 38. The sum of these percentages is 84%.
84% of observations will fall below 38
ITS C - Factor 6 out of the variable terms
