Answer:

The answer is 4

Step-by-step explanation:

You just divide 80 by 15.

She can jump rope 20 times in 15 seconds

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Given that Jen can jump rope 80 times in 60 seconds.

We have to determine the number of jumps can she make in 15 seconds.

Let the number of jumps would be x she can make in 15 seconds

Since she jumps at a constant ratio of seconds to jumps

So according to proportionality,

⇒ 80/60 = x/15

⇒ x = 15(80/60)

⇒ x = 20

Hence, she can jump rope 20 times in 15 seconds.

Answer:

11. A) 12

12. D)11

Step-by-step explanation:

11. We substitute x with 12 in 3(x)-11.

3(12)-11=

36-11= 25

We substitute x with 12 for the second equation (x+13).

12+13=25

Both answers match so the answer for #11 is 12.

12.We substitute x with 11 in 4(x)-4.

4(11)-4=

44-4=40

We substitute x with 11 for the second equation (2(x)+18)

2(11)+18=

22+18=40

Both answers match so the answer for #12 is 11.

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.

Step-by-step explanation:

dn means the difference (meaning what do you add/subtract to get the next number)

T0 means the term before the first one you got.

Tn = dn + T0

Tn = 2n + 0

Therefore our equation will be

Tn = 2n

For the red figure: Translate 1 unit down then 3 units left, and for the blue figure: Reflect the figure at the y-axis.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that:

The figures are given in the picture:

For the red figure: Translate 1 unit down then 3 units left.

For the yellow figure: translate 5 units down and then 2 units right

For the blue figure: Reflect the figure at the y-axis.

Thus, for the red figure: Translate 1 unit down then 3 units left, and for the blue figure: Reflect the figure at the y-axis.

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

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

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
