Answer:
32 days
Step-by-step explanation:
make a rate time distance chart:
r t d
first 5 | y | 5 | 5y
final days | y+6 | x-6 | (y+6)(x-6)
take y for planned rate and x for time till test
then make system of equations:
1. 5y+(y+6)(x-6) = 844
2. 768/y =x
/Henrietta knew the time till test, so we can assume that she planned in such a way that would mean she learned exactly 768 spells if she worked at the set rate. On this assumption we make 2
solve, and you get 2 options: x=-10/3 y =-144 (exclude, negative)
the second one is x=24 y=32 that works for us, so answer is she planned to learn 32 spells each day.
Answer: The test statistic value is -0.95.
Step-by-step explanation:
Since we have given that
Here, n = 4000
x = 170
So, 
So, Test statistic value would be
Hence, the test statistic value is -0.95.
Answer:
Step-by-step explanation:
first you need to put the equation in y=mx+b form
y-3=(-1/2)(x+4)
y-3= (-1/2x)+4
y=-1/2x+1
then you just graph
the y intercept is 1 and the slope is -1/2 so it’s going to be a negative graph and it starts from 1 on the y axis
Answer:
x = 20
Step-by-step explanation:
x^2 - 4x - 8 = 8
x^2 - 4x - 8 + 8 = 8 + 8
x^2 - 4x = 16
x (x - 4) = 16
x - 4 = 16
x - 4 + 4 = 16 + 4
x = 20
