Answer:
20 miles
Step-by-step explanation:
The formula for distance is
d =rt where r is the rate and t is the time
We need to convert the time to hours since the rate is in mph
15 minutes * 1 hour/ 60 minutes = 1/4 hour = .25 hours
d = (80 mph) * .25 hours
d = 20 miles
2^2 • 3 • 17 because 204 is not a prime number. Hope this helps.

Step-by-step explanation:
The given quadratic equation is expressed as
x² = 5 - x
Rearranging the equation to take the standard form of ax² + bx + c, it becomes
x² + x - 5 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = 1
c = - 5
Therefore,
x = [- 1 ± √(1² - 4 × 1 × - 5)]/2 × 1
x = [- 1 ± √(1 - - 20)]/2
x = [- 1 ± √21]/2
x = (- 1 + √21)/2 or x = (- 1 - √21)/2
Answer:
- we will reject H0:u=0.29 ( null hypothesis )
- Test static = -1.94, P-value ≈ 0.034
Step-by-step explanation:
Given data
significance level = 0.05
we will reject H0:u=0.29 ( null hypothesis )
This is because at 5% percent significance level the data gotten using excel
i.e. Test statistic = -1.94 and P-value = 0.034 it is evident that the charity used less than 29% of its donations for its expenses.
Answer:
5 Boxes
Step-by-step explanation:
Volume is Length * width * height
1 box = 4.5* 2 *4= 36
Each box is 36 cubic feet. Now divide the closet size by box size
185 cubic feet/36 cubic feet per box = 5.138
Since you can't have .138 of a box, and rounding up to 6 boxes is too much, the closet will hold 5 boxes (with .138 cubic feet left over).
