To determine the answer to this item, we first calculate the z-scores of the given data point through the equation,
z-score = (data point - mean) / standard deviation
For 5:
z-score = (5 - 7) / 1.7 = -1.176
This translates to a percentile of 11.97.
For 10:
z-score = (10 - 7) / 1.7 = 1.76
This translates to a percentile of 96.08.
The difference between the percentiles is 84.11. Thus, 84% of the students sleep between 5 to 10 hours.
We can solve this by using the formula:
(x, y) (x + a, y + b) = (5,-4) (-2,1)
So, plugging in the values and solving for a and b,
5 + a = -2
a = -8
-4 + b = 1
b = 5
Therefore, the translation is
(x,y) (x - 8, y +5)
Answer:
16y-24
Step-by-step explanation:
4(4y−6)
Use the distributive property to multiply 4 by 4y−6.
16y−24
Answer:
(0,-6)
Step-by-step explanation:
3x-4y=24
To find the y intercept, let x =0 and solve for y
3(0) -4y =24
-4y =24
Divide by -4
-4y/-4 = 24/-4
y = -6
The y intercept is
(0,-6)
