Answer:
The rate of change is 8
Step-by-step explanation:
put the 16 as the numerator then the 2 hours as the denominator then divide by 2 to get you 8 dollars for 1 hour
Answer:
2 20/24
Step-by-step explanation:
divide 4/2=2
then do 5/8÷3/4=5/8×4/3=20/24
u basically inverse 3/4
2 20/24
Answer:
True
Step-by-step explanation:
Given that:
M = 27, sample of n = 36 scores, µ = 30 and σ = 18.
The z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. If the z score is positive, the raw score is greater than the mean and if the z score is negative the raw score is less than the mean. The z score is given as:
Given that M = 27, this means that x = 27. Therefore:
This sample mean corresponds to a z-score of z = –1.00.
Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
This can be expressed by,
80 + 40 + 20 + 10 = 150
