Step-by-step explanation:

If he originally started with $25 then spent $5 he would then have $20 dollars left.

If he then bought 4 magazines using the last of his $20 (ignoring sales tax) you would have to divide $20 by 4 to get a total of $5 dollars for each magazine.

what is -9/14+2/7 as a fraction in simplest form

Answers

>> Answer

_________

[tex] \: [/tex]

[tex] - \frac{9}{14} + \frac{2}{7} = ...[/tex]

[tex] = \frac{2}{7} - \frac{9}{14} [/tex]

[tex] = \frac{(28 - 63)}{98} [/tex]

[tex] = \frac{ -35 }{98} [/tex]

[tex] = \boxed{ \bold{ - \frac{35}{98}}} [/tex]

Answer:

5/14

Step-by-step explanation:

-9 is just 9 so that makes 9/14 - 2/7.

Multiply 7 by 2 and that makes 14, do the same with the numerator and that makes 4/14 and 9/14 - 4/14 = 5/14

Use the point and the slope to graph cach line. Write the equation of the line.
The line passes through point (-1, 4) and has slope - 2.

Answers

Answer:

y=-2x+2

Step-by-step explanation:

We use the formula

y=mx+b, where m is the slope, b is the y intercept, and x&y are the coordinates.

We know that one point is (-1, 4)

and the slope is -2.

We are trying to find b.

In order to do that, we plug in what we know:

so,

4=-2(-1)+b

4=2+b

4-2=b

b=2

So now we go back to the original equation and use b as our value'

y=-2x+2

16 ==>> Length of PR

Step-by-step explanation:

==>> Since PQRS is a parallelogram the diagonals are symmetrically split by a shared midpoint: T

==>> Thus the values of A & B can be found by setting the sides to equal each other.

2B - 3 = B [add 3 and subtract B from both sides]

B = 3

4 = A

==>> Then to find the length of the diagonals: Plug the variables in and add both sides.

2(3) - 3   +   (3) =6

The correct matching of the elements to their values are:

16 ==>> Length of PR4 ==>> Value of A3 ==>> Value of B6 ==>> Length of QSWhat is a Parallelogram?

This refers to the plane that has four sides and their opposite sides are parallel.

Hence, because PQRS is a parallelogram, the diagonals are symmetrically split by a shared midpoint:

This means that the values of A & B can be found by setting the sides to equal each other.

2B - 3 = B

B = 3

A + 4 = 2A

4 = A

The number generator is fair. It picked white socks half of the time.

The number generator is not fair. The correct percentage of white socks was not chosen at all.

The number generator is not fair. In three experiments, it picked white socks 90% of the time.

The number generator is fair. It picked the approximate percentage of white socks most of the time.

Answers

Answer:

The number generator is fair. It picked the approximate percentage of white socks most of the time.

Step-by-step explanation:

Just took the test :3

Description  about the number generator : The number generator is fair. It picked the approximate percentage of white socks most of the time.

What is randomly selection?

Random selection is a part of the sampling technique in which each sample has an equal probability of being chosen.

According to question

White socks = 80%

Black socks = 20%

Randomly selecting 10 socks from the drawer .

Process repeated 10 times

According to dots on plot

Number white socks was selected in each round is   7,7,7,8,8,8,8,9,9,9 .

If we evaluate the number generator :

80% of the socks are white, and each trial selects 10 socks.  80% of 10 is 8, which is what the number generator picked most of the time.  

That means The number generator is fair.

Hence, The number generator is fair. It picked the approximate percentage of white socks most of the time.
