Answer:
x=-18
Step-by-step explanation:
What you have do do is look at the word <em>difference. </em>
Difference means subtraction so you will subtract x and -37.
x-(-37)=19. You will then make the negative a positive and subtract 37 from both sides.
x=-18 is your answer.
The formula for finding slope is (y2-y1)/(x2-x1). Therefore, you just substitute each number for the corresponding variables. y2 would symbolize 5 and y1 would symbolize -6. x2 would symbolize -4 and x1 would symbolize -9. Substitute it to make: 5-(-6)/-4-(-9). Solve it and therefore, you will get 11/5.

Answer:
1 5/24 + 7 22/24 = 8 27/24
Step-by-step explanation:
No change is required to the fraction on the first line:
1 5/24 = 1 5/24
The fraction on the second line can be multiplied by 2/2 to make its denominator 24.
7 11/12 = 7 22/24
The fraction on the third line is the sum of the fractions on the other two lines. It is an improper fraction. We know this because the integer portion of the sum is shown as 8, not 9, as it would be if the fraction were reduced.
5/24 +22/24 = 27/24
Then the sum is ...
1 5/24 +7 22/24 = 8 27/24
_____
If the fraction on the final line were reduced, the sum would be 9 3/24 = 9 1/8.
Answer:
Step-by-step explanation:
The Standard Deviation Rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated below
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations.
The distribution of the IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 15.
Therefore, the range of IQ scores that many (68%) people have is between
100 - 15 and 100 + 15
It becomes
85 to 115
