7*5*2/7*3

5^0/2^-3 times 2^-9
1/(1/2^3)(1/2^9)
1/(1/8)(1/512)

so now we have
(10/3)^2 times 1/64
100/9 times 1/64
100/576
25/144

you should group them better so it is easier to read

Yes so you want to use pemdas.

First parenthesis:
(5*2/3)^2 = (10/3)^2 = 100/9 * (1/1/8)*1/(2^9)) = 100/9*(8/512) = 100/9(1/64) = 25/144 = .17361

HELP PLZ <br> i need help with this math side i just need b,c,d a =4x+2y=16
tino4ka555 [31]

Answer:

Please check the explanatio.

Step-by-step explanation:

Solving Part b)

We know that the slope-intercept form of the equation line is

y=mx+b

where m is the slope and b is the y-intercept

Given the equation

4x+2y=16

Re-writing the equation in the slope-intercept form

4x+2y=16

y=-2x+8

Here, m=-2 and b=8

Thus, the equation in the slope-intercept form will be:

y=-2x+8

Solving Part c)

As you sold two pounds of cheddar cheese.

i.e. y=2

substituting y=2 in the slope-intercept form of the line equation

y=-2x+8

2=-2x+8

Subtract 8 from both sides

-2x+8-8=2-8

-2x=-6

Divide both sides by -2

\frac{-2x}{-2}=\frac{-6}{-2}

x=3

You sold 3 pounds of swiss cheese.

Solving Part d)

y=-2x+8

putting x=2.5 in the equation

y=-2x+8

2=-2\left(2.5\right)+8

2=3

The sides are not equal

<em>FALSE</em>

Thus, x=2.5 does not make any sense in the context of the problem.

According to​ psychologists, IQs are normally​ distributed, with a mean of 100 and a standard deviation of 15 . a. What percenta
Angelina_Jolie [31]
Answer: 34%.

By definition of normal distribution, ≈68% of the data is within 1 standard deviation of the mean. Therefore 68% of IQs are between 85 and 115, and half of that is on the lower end, 85 to 100.

Answer:

I put in y = 2-x. I believe that was the equation you asked a table for. If it is another equation please tell me or just download or look up Desmos. Desmos helps create graphs and tables. I hope this helps. Have a great rest of your day!
