Answer:
Step-by-step explanation:
The graph of the absolute value function looks like a V that opens UP and has its vertex at the origin, (0, 0). There are no restrictions on the input, x, so the domain is (-infinity, infinity).
On the other hand, this function has no values less than zero. Its range is
[0, infinity).
Answer:
when reflected across the y-axis the points will reflect onto the other side on the y-axis.
when reflected over the x-axis the points with reflect onto the x-axis

<span>solution:
we have, mean =8.4 hrs, std. deviation = 1.8 hrs, sample size n = 40 , X = 8.9
Probability(X<8.9) = ?
we know that, Z = (X - mean)/(std. deviation/(sqrt. n)) = (8.9 - 8.4)/(1.8/(sqrt.40))
Z = 1.7568
from standard normal probabilities table, we have , P(Z<1.7568) = 0.9608
Hence, probability that the mean rebuild time is less than 8.9 hours is 0.9608</span>
Answer:
4y
Step-by-step explanation:
y - -3y
Subtracting a negative is like adding
y+3y
Combine like terms
4y
