Answer: So the answer would be: 5hrs (sry if its wrong im only an 8th grader lol)
Step-by-step explanation:
+22 - 13 = 35 degrees difference
3 A.M to 10 A.M = _______ hours
Divide 35 by the number of hours.
Answer:
Area of the rectangular doormat = 2/5 m²
Step-by-step explanation:
Length of the rectangular doormat = 4/5m
Width of the rectangular doormat = 1/2m
What is the area of the doormat?
Area of a rectangle = length × width
= 4/5m × 1/2m
= (4×1) / (5×2)
= 4 / 10
= 2/5 m²
Area of the rectangular doormat = 2/5 m²
Answer:
Option B) 0.1032; fail to reject 
Step-by-step explanation:
We are given the following information in the question:
We used two tailed z-test to perform the hypothesis.

Level of significance, α = 0.05
We have to calculate the p-value.
We calculate the p-value from the normal standard z-table.
p-value = 0.1032
Since,
p-value > Level of significance
We fail to reject the null hypothesis and accept it.
Option B) 0.1032; fail to reject null hypothesis
Let x = no. of 10 oz cups sold
Let y = no. of 14 oz cups sold
Let z = no. of 20 oz cups sold
:
Equation 1: total number of cups sold:
x + y + z = 24
:
Equation 2: amt of coffee consumed:
10x + 14y + 20z = 384
:
Equation 3: total revenue from cups sold
.95x + 1.15y + 1.50z = 30.60
:
Mult the 1st equation by 20 and subtract the 2nd equation from it:
20x + 20y + 20z = 480
10x + 14y + 20z = 384
------------------------ subtracting eliminates z
10x + 6y = 96; (eq 4)
Mult the 1st equation by 1.5 and subtract the 3rd equation from it:
1.5x + 1.5y + 1.5z = 36.00
.95x + 1.15y+ 1.5z = 30.60
---------------------------subtracting eliminates z again
.55x + .35y = 5.40; (eq 5)
Multiply eq 4 by .055 and subtract from eq 5:
.55x + .35y = 5.40
.55x + .33y = 5.28
--------------------eliminates x
0x + .02y = .12
y = .12/.02
y = 6 ea 14 oz cups sold
Substitute 6 for y for in eq 4
10x + 6(6) = 96
10x = 96 - 36
x = 60/10
x = 6 ea 10 oz cups
That would leave 12 ea 20 oz cups (24 - 6 - 6 = 12)
Check our solutions in eq 2:
10(6) + 14(6) + 20(12) =
60 + 84 + 240 = 384 oz
A lot steps, hope it made some sense! I hope this helps!! ;D
