Answer:

Step-by-step explanation:
1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to 


substituting the value of y in
:

substituting x=-1 in y= -4-5x:
(upon solving, you should get this)

2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)


-1= 2 x 1 +c
-3=c
Hey there!
A survey is used to define the public opinion on a certain matter.
Therefore, the clearer and more concise it is, the better the answer will be from the people that take the survey.
Hope this helps!
Answer:
Q3 = 65.98 inches.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be 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.
Normally distributed with a mean of 64.9 inches and a standard deviation of 1.6 inches.
This means that 
Find Q3, the third quartile that separates the bottom 75% from the top 25%.
This is X when Z has a pvalue of 0.75. So X when Z = 0.675.




Q3 = 65.98 inches.
Answer:
11. x = 5
12. x = 24
Step-by-step explanation:
11.
8x° + 140° = 180°
(Linear pair angles)
8x° = 180° - 140°
8x° = 40°
x ° = 40°/8
x° = 5°
x = 5
12.
2x° + 42° = 90°
(complementary angles)
2x° = 90° - 42°
2x° = 48°
x ° = 48°/2
x° = 24°
x = 24
