Answer:

Each group received 3.75 pounds

You divide 15 by 4 and get 3.75

Answer:

Step-by-step explanation:

The length is (x-1), not (2-1).

area = (x-1)(x+3) = 12 ft²

x²+2x-3 = 12

x²+2x-15 = 0

(x+5)(x-3) = 0

x = -5, 3

-5 is an extraneous solution, so x=3.

Length = x-1 = 2 feet

Width = x+3 = 6 feet

=============================================================

Explanation:

Define the following events

We are given the following probabilities

Then we're further told that "if it is dry, then the probability someone will arrive on time is 4/5". We can condense that into the notation

P(T given D) = 4/5

The "given D" means that we know 100% that event D has occurred. So we're seeing how event T behaves because of D occurring. In other words P(T given D) is the same as saying "What is P(T) when we know D has happened?"

-------------------------

The instructions also mention that "If it rains, the probability someone is on time is 2/5" tells us we have the notation

P(T given R) = 2/5

And also, the probability someone is on time if it is snowy is

P(T given S) = 1/10

due to it saying "If it snows, the probability that someone will arrive on time is 1/10".

-------------------------

To recap so far, your teacher told you these three conditional probabilities

They are conditional due to the "given" as part of the probability. They depend on the given event happening.

Subtract each fraction from 1 and we end up with these complementary probabilities

I'm using the idea that P(A)+P(B) = 1, where A and B are complementary events. One or the other event must happen. Either you are on time, or you are late.

---------------------------

Recall the conditional probability formula is

P(A given B) = P(A and B)/P(B)

which rearranges to

P(A and B) = P(A given B)*P(B)

We'll use this idea to get the following

This means,

P(L) = P(L and D) + P(L and R) + P(L and S) ..... law of total probability

P(L) = 1/10 + 1/5 + 3/20

P(L) = 2/20 + 4/20 + 3/20

P(L) = (2+4+3)/20

P(L) = 9/20 is the probability someone is late

Step-by-step explanation:

Answer:

-1/2

Step-by-step explanation:

hello :

f(x)=(−2)^3 (3)^0 (4)^−2

(−2)^3  = -8

(3)^0 =1

(4)^−2 1/ (4)^2 =1/16

so : f(x) = (-8)×(1)×(1/16) = -8/16 = -1/2

Answer:

432 inches.

Step-by-step explanation:

The formula for finding the area of a triangle is;

[tex]\frac{b*h}{2}[/tex]

Using this, we can find the area of each individual piece.

[tex]\frac{6*6}{2} =18[/tex]

Now that we have this, we simply multiply 18 by 24, which gives us 432.

Answer:

2

Step-by-step explanation:

[tex]50 = 2 \times 5 \times 5 \\ \\ 42 = 2 \times 3 \times 7 \\ \\ 30 = 2 \times 3 \times 5 \\ \\ common \: factor \: = 2 \\ \\ gcf = 2[/tex]

Answer:

Money need to save each month  = $576.92 each month

Step-by-step explanation:

Given:

Amount of money need to save = $125,000 - $35,000 = $90,000

Number of year remain = 18 - 5 = 13 year

Number of months = 13 x 12 = 156 months

Find:

Money need to save each month

Computation:

Money need to save each month = 90,000 / 156

Money need to save each month  = $576.92 each month

Answer:

13.3 (rounded in the tenth place)

Step-by-step explanation:

equation: a^2 + b^2 = c^2

What we know :

a = 20^2 = 400

b = what we are looking for

c = 24^2 = 576

Our equation will be looking like :

20^2 + b^2 = 24^2

400 + b^2 = 576

Now we  subtract 400 into 576

which equals 176 now we square root it

and get 13.2664 but we gotta square root it and that will lead you to have 13.3 as your answer

Answer:

31.24

Step-by-step explanation:

a^2+b^2=c^2

20^2=400

24^2=576

576+400=976

√976=31.24

Answer:

This is a nonrigid transformation called a dilation.

Step-by-step explanation:

A dilation is when a pre-image's dimensions are altered in proportion with the pre-image. The image has a proportional relationship with the pre-image. The shape can get larger or smaller in size.

Answer:

Mean: 3.5263157894737

Median: 3

Mode: 3

Step-by-step explanation: The mode is 3 because the mode is for which number pops up the most, which is 3.

I got the median by crossing out 8 from the left and the right of the number set and got 3 as the last number.

I got the mean by adding up all the numbers and divided it by the amount of numbers in the set.

Answer:

you mean the decimal point?

Step-by-step explanation:

You will know when you cross the decimal point when multiplying.

Answer: it would just be like putting a comma normally, just all you have to do is get your new number but then just add both the comma and decimal it shouldn’t effect on where its put! If that’s what your asking!

Answer:

length =√area use this formula

The side length of square can be found by taking the square root of Area.

Square are closed polygons which consist of four sides and four angles.

Each angle is 90 degree.

All the sides are of equal length.

So, by the definition of square, we know that the side lengths of square are equal.

The formula to calculate the area of the square is,

Area = a², where a is the length of one side of the square.

Let Area be given, let it be equal to A.

Then,

a² = A

Taking square root on both sides,

a = √A

Hence the side length is found by taking the square root of Area.
