Answer:
W = 6
Step-by-step explanation:
L x W x H = V
L = 4W
H = W + 4
V = 1440
Plug in and solve for W.
4W x W x (W+4) = 1440
4W^2 x (W+4) = 1440
W^2 (W+4) = 360
A combo that came quickly to mind was 36 and 10 to make 360.
6^2 = 36
6 + 4 = 10
36 x 10 = 360
Therefore, W = 6.
a) 2 pounds of Sour Patch Kids
b) 3 pounds of Rolos
Step-by-step explanation:
Given,
Pounds of candy bought = 5 pounds
Cost of sour patch per pound = $2.25
Cost of Rolos per pound = $1.75
Total amount spent = $9.75
Let,
x = Number of pounds of sour patch
y = Number of pounds of rolos
x+y=5
x = 5-y Eqn 1
2.25x+1.75y=9.75 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 0.5
Putting y = 3 in Eqn 1
a) 2 pounds of Sour Patch Kids
b) 3 pounds of Rolos

Answer:
The appropriate hypothesis test is: a. independent-measures t test.
Step-by-step explanation:
The appropriate hypothesis test is: a. independent-measures t test.
It is needed to take two samples of each group, and compute their proportions. Then, the hypothesis test has to compare these proportions in function of what the hypothesis claim.
Since opposite angles and sides are equal, then the quadrilateral ABCD is a parallelogram.
Given that, ABCD is a quadrilateral, segment AB is congruent to segment CD, ∠1 is congruent to ∠2.
We need to prove that ABCD is a parallelogram.
<h3>
How to prove a given quadrilateral is a parallelogram?</h3>
If one pair of opposite sides of a quadrilateral are both parallel and congruent, then it’s a parallelogram.
From the given quadrilateral ABCD:
AB=CD (Given)
∠1=∠2 (Given)
AC=AC (Diagonal)
From ASA congruency ΔABC and ΔADC are congruent.
By CPCT, AD=BC and ∠ABC=∠ADC.
Since opposite angles and sides are equal, then the quadrilateral ABCD is a parallelogram.
