Answer:
y = 23x + 182
Step-by-step explanation:
m = 23 (parallel line has same gradient)
y = 23x + c
H(-8,-2)
-2 = 23(-8) + c
c = 182
y = 23x + 182

Answer:
-3/4
Step-by-step explanation:
x - 1 = 5x + 2
or, 5x + 2 = x - 1
or, 5x - x = - 1 - 2
or, 4x = - 3
or, x = - 3 / 4
Answer:
0.1069 = 10.69%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:

Between 57 and 69
This is the pvalue of Z when X = 69 subtracted by the pvalue of Z when X = 57. So
X = 69



has a pvalue of 0.9918
X = 57



has a pvalue of 0.8849
0.9918 - 0.8849 = 0.1069 = 10.69%
Answer: he fly 107.76 miles per hour for each hour
Step-by-step explanation:
Charles Lendbergh had his first solo flight across the Atlantic Ocean. He flew 3,610 miles in 33.5 hours.
Speed = distance /time
If he flew about the same number of miles each hour, it means that the number of miles that he flies in each hour would be
3610/33.5
= 107.76.miles per hour.
