Answer:

It would be written as: 2.5 x 10^-4.

This is because you must have one number in front of the decimal point in scientific notation and to do that you must move it back four spaces. I hope that helps!

My thousands digit is 4
ElenaW [278]

The values In wxyz are mathematically given as

W=4

y=5

X=0

<h3>What is  the values In XYZ?</h3>
  • My one's digit and my tens digit together make up a total of seven.
  • My one digit has three more digits than my tens digit does.

Let the equation for the number be: wxyz.

  • Digits at tens place = yz
  • Diglt at ones place = z

Generally, the equation for is  mathematically given as

z+y=7 ......1

y=2+3 .......2

solving further

z+3+z-7

2z 7-3

z=2

Putting the value of z Within the second equation:

y=z+3 y=2+3

y=5

1. The digit in the thousands place of my number is 4, and

2. The digit in the hundreds place is four fewer than the digit in the thousands place.

W=4

X=w-4

x=4-4

X=0

In conclusion, the values In wxyz are

W=4

y=5

X=0

A population has a mean µ = 6 and ∑x = 48. How many scores are in the population?
maks197457 [2]

Answer:

8

Step-by-step explanation:

Recall the formula for the population mean of a data set:

\mu=\frac{\sum x}{N}

We already know that μ is 6 and the sum is 48. Substitute:

6=\frac{48}{N}

Divide both sides by 48:

\frac{1}{8}=\frac{1}{N}

Reciprocal of both sides:

N=8

Thus, there are 8 scores in the population size.

And we're done!

HELP! I don’t know what to do for #4. well i don’t know what to put for another equation. i Dont need help solving i just need h
OLga [1]

Let s = #small notebooks

Let L = #large notebooks

 

We Can set up two equations from the info given.

 

s + L = 6           bought 6 notebooks total

8s + 10L = 56    spent $56

 

Solve equation 1 for one variable.

L = 6-s

 

Plug 6-s in equation 2 in place of L

and solve for s

 

8s + 10(6-s) = 56

8s + 60 - 10s = 56

-2s + 60 = 56

-2s = -4

s = (-4)/(-2)

s = 2

 We know s+L = 6 and s=2

2+L = 6

L = 4

 4 large notebooks and 2 small notebooks

were purchased
