Answer:
3m - 25
Step-by-step explanation:
3m - 25 will represent how many minutes she practiced this week:
3m represents 3 times the number of minutes she practiced last week. Then, subtract 25 from this.
This will represent 25 minutes less than 3 times the number of minutes she practiced last week.
Answer:
Hi there!
The correct answer is:
a. 27831.05
Step-by-step explanation:
Since they gave you the equation for the line of best fit: y = 1.9x + 21
a. solve for x: 52900= 1.9x + 21
minus 21 on both sides to get 1.9x = 52879
then divide 1.9 on both sides to get x= 27831.05
Answer:
1.734
Step-by-step explanation:
Given that:
A local trucking company fitted a regression to relate the travel time (days) of its shipments as a function of the distance traveled (miles).
The fitted regression is Time = −7.126 + .0214 Distance
Based on a sample size n = 20
And an Estimated standard error of the slope = 0.0053
the critical value for a right-tailed test to see if the slope is positive, using ∝ = 0.05 can be computed as follows:
Let's determine the degree of freedom df = n - 1
the degree of freedom df = 20 - 2
the degree of freedom df = 18
At the level of significance ∝ = 0.05 and degree of freedom df = 18
For a right tailed test t, the critical value from the t table is :
1.734
So, we have 4 cups of flour and 6 cups of sugar and we need to know how many cups of sugar per cup of flour does the recipe require. Because it is requested to know how many cups of sugar per cup of flour does the recipe require, we need to divide the amount of flour and sugar by the amount of flour, and we will know what we need to know.
4 cups of flour / 4 = 1 cup flour
6 cups of sugar / 4 = 6/4 = 3/2 = 1 1/2 cups of sugar per cup of flour is the solution
Answer:
y=-3/4x+3
Step-by-step explanation:
subtract 3x from both sides: 4y=-3x+12
Divide both sides by 4: y=-3/4y+3
