Answer: x ∗ 5 = y or y = x∗5

Answer:

1. 2/21

2. 7/45

3. 9/26

4. 4/61

5. 3/29

6. 8/61

Step-by-step explanation:

I'll just explain number one, since you can do the same thing to solve all the others.

You start with 10 1/2. You can make this an improper fraction by multiplying 10 and 2, then adding one. This leaves you with 21/2. The reciprocal of a fraction is just the numerator and denominator of the fraction flipped. So, you  get 2/21.

Answer:

5 (x+2) +2x is equal to 7x + 10

Step-by-step explanation:

To find the value of this equation you would have to apply the distributive property by changing 5 (x+2) to 5x +10. (When applying the distributive property you will always multiply the numbers in the parentheses by the number on the left of it). Then you would combine like terms by adding 2x and 5x together. You will then have 7x + 10.

Step-by-step explanation:

1.) Distribute = 5x+10

2.) Collect Like-Terms = 5x & +2x

3.) Add 5x and +2x , which = 7x

Now you have your answer, which is: 7x + 10.

Answer: angle x is 52°

Assuming the line JK is parallel to HI. That should be given.

Step-by-step explanation:

Angle JKA is congruent to angle HIA, so both measure 62°

Add measure of AHI to JKA.

66+62= 128.

Angles of a triangle always add up to 180° so you can subtract 128 from 180 to find x.

180-128= 52°

Answer:

C. (1,760, 3,530, 5,280)

Step-by-step explanation:

In order to answer this question, you simply have to replace the variable 'x' with the 3 numbers Lilah has, which are 5,280,    10,560, and     15,840:

y(x) = 1/3 (5280) = 1760

y(x) = 1/3 (10560) = 3520

y(x) = 1/3 (15840) = 5280

So, the correct answer is C. (1,760, 3,530, 5,280)

Answer:

(a) Explained below.

(b) 0.0294

(c) 0.0173

(d) 0.09827

(e) 0.0452

Step-by-step explanation:

The complete question is:

According to an​ airline, flights on a certain route are on time 80​% of the time. Suppose 25 flights are randomly selected and the number of​ on-time flights is recorded.

​(a) Explain why this is a binomial experiment.

​(b) Find and interpret the probability that exactly 16 flights are on time. ​

(c) Find and interpret the probability that fewer than 16 flights are on time.

​(d) Find and interpret the probability that at least 16 flights are on time.

​(e) Find and interpret the probability that between 14 and ​16 flights, inclusive, are on time.

Solution:

(a)

Let the random variable X be defined as the number of​ on-time flights.

A Binomial experiment has the following properties:

If a random variable X is used in an experiment and the experiment has all the above mentioned properties, then the random variable X is known as a binomial random variable.

All of these properties can be confirmed for the random variable X.

Thus, this is a binomial experiment.

(b)

Compute the probability that exactly 16 flights are on time as follows:

[tex]P(X=16)={25\choose 16}(0.80)^{16}(0.20)^{25-16}[/tex]

        [tex]=2042975\times 0.0281475\times 0.000000512\\=0.029442375072\\\approx 0.0294[/tex]

Thus, the probability that exactly 16 flights are on time is 0.0294.

(c)

Compute the probability that fewer than 16 flights are on time as follows:

[tex]P(X<16)=\sum\limits^{15}_{x=0}{{25\choose x}(0.80)^{x}(0.20)^{25-x}}[/tex]

                 [tex]=0.0000+0.0000+....+0.011777\\=0.0173[/tex]

Thus, the probability that fewer than 16 flights are on time is 0.0173.

(d)

Compute the probability that at least 16 flights are on time as follows:

[tex]P(X\geq 16)=1-P(X<16)[/tex]

                 [tex]=1-0.0173\\=0.9827[/tex]

(e)

Compute the probability that between 14 and 16 ​flights, inclusive, are on time as follows:

[tex]P(14\leq X\leq 16)=\sum\limits^{16}_{x=14}{{25\choose x}(0.80)^{x}(0.20)^{25-x}}[/tex]

                          [tex]=0.004+0.0118+0.0294\\=0.0452[/tex]

Thus, the probability that between 14 and 16 ​flights, inclusive, are on time is 0.0452.

Options 1 and 4 are the only other parallel lines

Step-by-step explanation:

Plug the equation into a graphing calculator and observe your results.

Answer:

The answers are y = −4x, 16x + 4y = 9, and y = −4x + 15

Step-by-step explanation:

y=-4x has the -4 as slope so it parallel

y = −4x + 15 also has the -4 as a slope so it parallel

16x + 4y = 9 u have to solve.

4y=-16x+9 First step is to subtract -16 both sides (which just tosses -16 to the other side where the 9 is.

y=-4x+2.25 Divide everything by 4

Step-by-step explanation:

Algebraic Expressions

This problem deals with the ability to manage algebraic expressions in two variables.

Recall the perimeter of a triangle is the sum of its three sides. We already know the perimeter of the triangle is:

P=13x+5y

We also know the lengths of two of its sides are 2x+y and 8x+4y. The sum of those sides is:

S2=2x+y+8x+4y

Joining like terms:

S2=10x+5y

The third side must be the difference between the perimeter and the sum above:

S3=13x+5y-(10x+5y)

Operating:

S3=13x+5y-10x-5y

Joining like terms:

S3=3x

The length of the third side is 3x

The Midpoint between 50 and 49 is 49.5

The exact middle point between two numbers is referred to as the midpoint. By adding the two numbers together and then dividing the result by two, we can determine the midway of the two supplied values. It is the two numbers' average.

Given:

First number= 50

and second number= 49

So, the Midpoint between 50 and 49

= First number + second number/2

= 50+ 49 / 2

= 49.5
