Answer: Jim can lay 25 tiles per hour.
Step-by-step explanation:
Let be "x" Jim's rate and "y" Pete's rate.
We know that Jim completed half the floor in 4 hours, then:
And Pete completed the other half of the floor in 2 hours, then:
Since Jim completed half the floor and Pete completed the other half:
[Equation 1]
We also know that Pete can lay 25 more tiles per hour than Jim, then:
[Equation 2]
Then, we can substitute Equation 2 into Equation 1 and solve for "x":
Therefore, Jim can lay 25 tiles per hour.
The answer to fill in the blank is 10 , so 10 units
Step-by-step explanation:
Step-by-step explanation:
just think - what does it mean to translate (shift) a graph upward by 5 units ?
does the graph change in its content ? no. all the functional result value (= y values or coordinates) are still calculated as before, BUT before marking them on the chart the y values are moved up by 5 units. that means they are increased by 5 (that is the only way to move something "up" on a coordinate grid).
so, in other words, f(x) is nothing else but h(x), but it increases the results of h(x) consistently by 5.
h(x) = 2x² + 4
f(x) = h(x) + 5 = 2x² + 4 + 5 = 2x² + 9
Answer:
Mean = 1.5
Step-by-step explanation:
We are given a table of probability distribution of students the numbers of hours studied.
We need to find the mean of the probability distribution.
Formula of mean = sum of product of probability and random distribution value.
Now we will calculate the mean
Thus, Mean of the given table is 1.5
Y=2x-8 i believe would be ur answer hope this helps
