Answer:
11.1554 feet
Step-by-step explanation:
The conversion rate for meters to feet is multiplying the given meters by 3.281 so [tex]3.4*3.281[/tex] (The formula is an approximation.) For the answer I would most likely put down 11.15 feet.
Alice passes through four tra¢ c lights on her way to work, and each light is equally likely to be green or red, independent of the others. Suppose that each red light delays Alice by exactly two minutes. What is the variance of Aliceís commuting time?
Using the binomial distribution, it is found that the variance of Alice's commuting time is of 2 minutes squared.
For each light, there are only two possible outcomes, either it is red, or it is green. The lights are independent of others, hence the binomial distribution is used to solve this question.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The variance of the binomial distribution is:
[tex]V(X) = np(1 - p)[/tex].
In this problem:
She passes through four lights, hence n = 4.The lights are equally as likely to be red or green, hence p = 0.5.The variance for the number of red lights is:
V(X) = 4(0.5)(0.5) = 1
Since each red light delays Alice by exactly two minutes, the variance of Alice's commuting time is of:
2 x 1 = 2 minutes squared.

Answer:
m - 7.50 = 12.50
and
m = 7.50 + 12.50
Step-by-step explanation:
The best answers would be:
m - 7.50 = 12.50
and
m = 7.50 + 12.50
First of all, let's figure out what the question is asking us:
The question is asking us to find the amount of money on the gift card
It tells us to use "m" for "the amount of money on the gift card"
Now that we know the following, we can put together the equation
m = the amount of money on the gift card
$7.50 = cost of the book
$12.50 = amount remaining
Since he receives the gift card and then buys a book that costs $7.50, we are going to "have to subtract $7.50 from m". And we know that $12.50 is remaining, so we "make the equation equal to 12.50".
So, let's set up the equation:
m - 7.50 = 12.50
Now that we know the equation, we can solve for "m"
m - 7.50 = 12.50
Step 1: Add 7.50 to both sides.
m − 7.50 7.50 = 12.50 + 7.50
Step 2: Simplify
Answer: m = 20
Another way you can set up this equation is:
m = 7.50 + 12.50
Because we want to find "m", we set it equal to the equation. Since Salim bought a book for $7.50 and had $12.50 remaining, we want to find how much he had on the gift card that made him have $12.50 remaining when he bought the book. So, we have to add 7.50 and 12.50, to find how much is on the gift card.
So, the equation "m = 7.50 + 12.50", makes sense when solving for "m"
Hint: Once you have realized that the equation has Like Terms on the same side you must Combine the Like Terms by either adding them together or subtracting them.
Now that we know the equation, let's solve it
m = 7.50 + 12.50
Step 1: Combine like terms
m = (7.50 + 12.50)
m = 20
Since both equations equal $20 and both make sense, we can conclude that these are the best options.

How does ((x) = 4 • 6^x change over the interval from x=2 to x=3
Answer:
f(x) increases by a factor of 6
Step-by-step explanation:
[tex]f(x) = 4 *6^x[/tex]
[tex]f(2) = 4 *6^2[/tex]
[tex]f(2) = 4 *36[/tex]
[tex]f(2) = 144[/tex]
[tex]f(x) = 4 *6^x[/tex]
[tex]f(3) = 4 *6^3[/tex]
[tex]f(3) = 4 *216[/tex]
[tex]f(3) = 864[/tex]
f(x) increases by a factor of 6
144 * 6 = 864

What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
A square and a rectangle are in the given figure.
Now,

Length = 3 ft
Wide = 2 ft
Area = 3 x 2 = 6 ft²
Now,
Total area:
= 25 + 6
= 31 ft²
Thus,
The total area is 31 ft².

The length and breadth of a room are in in the ratio of 3:2
Find the length of breadth is 8.6 meters
Answer:
12.9 m
Step-by-step explanation:
Let length = 3x, then breadth is 2x
if breadth is 8.6 m, so 2x = 8.6 m, x = 8.6/2 = 4.3 m
length = 3x = 3* 4.3 = 12.9 m

Suppose that the distance a car travels varies directly with the amount of gasoline it uses. A certain car uses 8 gallons of gasoline to travel 232 miles. If the car travels 435 miles, how much gasoline does it need? gallons $ ?
Answer:
Mileage ÷ Gallons= Miles per gallon.
232 miles ÷ 8 Gallons = 29 miles per gallon
Mileage÷ Miles per gallon= Gallons
435 miles÷ 29 miles per gallon= 15 gallons
as for the $ sign, that variable is not there.

if n = 11 and p = 5 what is the value of the expression 18 - n - 2 + p
Answer:
10
Step-by-step explanation:
If n = 11 and p = 5, we can just substitute the values in for n and p in the equation 18 - n - 2 + p.
The new equation would be 18 - 11 - 2 + 5.
Using PEMDAS, we get the answer of 10.
18 - 11 = 7
7 - 2 = 5

We are given arc KL is 12x+4, arc KJ is 8x-6, and angle E is 99 degrees. What is the measure of angle K?
46 degrees
74 degrees
81 degrees
99 degrees
Answer:
81°
Step-by-step explanation:
m(arc)JKL = 2m<E = 2(99°) = 198°
m(arc)JEL = 360° - m(arc)JKL
m(arc)JEL = 360° - 198° = 162°
m<K = (1/2)m(arc)JEL = 162°/2 = 81°
