Step-by-step explanation:
The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.

Walk
a) Complete the tree diagram.
b) Show that the probability that Lyn
walks at least one way is 0.88.
Answers
I’m forced to write an explanation, sorry for the useless text
The probability tree has been drawn below and the probability that Lyn
walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks.
What is probability?The probability of an event occurring is defined by probability.
Do not take underestimate probability it has several uses in daily life whether forecasts like that.
As per the given probability tree,
(a)
The probability in branches adds to 1 thus,
0.2 + probability that she walks to the shop = 1
Probability that she walks to the shop = 1 - 0.2 = 0.8
The probability in the same branches multiplies as,
The probability that she took a bus to the shop x from the bus she again took the bus.
Similarly, the tree diagram has been drawn below.
(b)
The probability is 0.88 lies in that Lyn walks at least one way 0.88 is when she reaches the shop by bus and from the bus, she walks.
Hence "walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks".

What is the volume of the rectangular prism?
512 in 3
64 in 3
256 in 3
128 in 3
Answers
Answer and Step-by-step explanation:
First, we need to know what the formula is for finding the volume of a rectangular prism.
The volume formula for a rectangular prism is as follows:
V = b (base) * w (width) * h (height)
Essentially, we just take the height, base, and width, and multiply them together. Order doesn't matter here.
So, let's multiply 8 by 8 by 4.
8 * 8 * 4 = V
64 * 4 = V
256 = V
256 [tex]in^{3}[/tex] is the answer.

Luke and Seth each need to buy the same amount of fencing for their gardens. While Seth's garden is square in shape, Luke's garden is rectangular with the length 3 feet longer than Seth's. Luke's width is half of the length of his own garden. How much fencing did each buy?
Answers
A = Lw (Area equal length times width)
A = 48 (the garden's area is 48 ft2)
L = w + 2
We have values for our variables, so let's plug them in:
48 = w(w + 2)
Distribute:
48 = w2 + 2w
Subtract 48 from both sides:
0 = w2 + 2w - 48
AS you can see, we now have a quadratic. From here we need:
m + n = 2 and
m * n = -48
When we break up the quadratic into (w + m)(w + n)
48 is an even number divisible by 3, so it'll be also be divisible by 6:
48 / 6 = 8
8 + (-6) = 2
8 * -6 = -48, so:
0 = (w + 8)(w - 6) →→ 0 = w + 8, or 0 = w - 6
w = -8 or 6
We can't have a negative width, so it cannot be -8, therefore, the width is 6 ft. I'm sure you can find the length from here.

Arbitron Media Research Inc. conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for a sample of 10 men was 37 minutes per day. The standard deviation was 13 minutes per day. The mean listening time for a sample of 16 women was also 37 minutes, but the standard deviation of the sample was 14 minutes. At the 0.10 significance level, can we conclude that there is a difference in the variation in the listening times for men and women?
Answers
Answer:
We reject H0; that there is significant evidence to support that there is difference in the variation in the listening times for men and women
Step-by-step explanation:
Given that :
n1 = 10 ; s1 = 13 ; n2 = 16 ; s2 = 14 ; α = 0.1
Null : H0 : σ1² = σ2²
Alternative : H1 : σ1² ≠ σ2²
To compute the test statistic ; using the Ftest:
F-test = σ2² / σ1² = 14² / 13²
F-test = 14²/13² = 196 / 169 = 1.1597
Decision region :
Reject Null, H0 ; if
Ftest < Fcritical
F critical at:
At α/2 = 0.10/2 = 0.05
df_numerator = 16 - 1 = 15
df_denominator = 10 - 1 = 9
Using F critical calculator :
Fcritical = 3.006
1.1597 < 3.006
Since, Ftest is lesser than Fcritical, then we reject H0
