What is the median of the data set shown?34, 86, 12, 56, 21, 98, 72, 34, 21, 34, 45, 23, 97, 44
alex41 [277]

Answer: The median of the data is 34

Step-by-step explanation: the reason why it is 34 is because when your dealing with medians you want to put down the number that you see the most of for example you see 34 three times so the number you see the most is 34 so the answer is 34

Craig saved $3,655.11, and Yegar saved $4,190.67. How much more did Yegar save than Craig? A. $536.66
STatiana [176]
This is a simple subtraction problem, but since you are in Elementary School, I will help you out.

Subtract $4,190.67 by $3,655.11 (remember, the bigger number should come first)

 4,190.67
<span>-3,655.11
</span>         ...56

When a small number is on top of a bigger number, borrow 1 number from the number next to it (in this case, 0 is smaller than 5, so you must borrow 1 number from 9, making it to 8), then add the small number by 10 (0+0=10)
<span>Then we continue...

</span> 4,190.67
<span>-3,655.11
</span>      35.56

Do the same thing with 4 and 1.

 4,190.67
<u>-3,655.11</u>
   535.56

<em><u>Answer: $535.56</u></em>

What is each number in scientific notation?
Vladimir [108]

0.00037 = 3.7×10^-4

37,000 = 3.7×10^4

_____

The exponent of 10 is the place-value multiplier that the most-significant digit has.

In the first number, the most-significant digit (3) is multiplied by 0.0001 to find its place value. Of course 0.0001 = 10^-4.

In the second number, the most significant digit (3) is multiplied by 10,000 to find its place value. You know that 10,000 = 10^4.

Need help with finding my solution and graphing !
konstantin123 [22]

Answer:

Step-by-step explanation:

Both the equations that you modelled are correct.

Use the substitution method to solve the system of equations

R+C = 526\\5R+4C=2327\\

Take the first equation

R+C=526\\C=526-R

Now this becomes our third equation and now insert it into our second equation

5R+4C=2327\\5R+4(526-R)=2327\\5R+2104-4R=2327\\R=2327-2104\\R=223

Now insert R = 223 in any equation. Lets insert it into equation number three

C=526-R\\C=526-223\\C=303

So 223 number of roll papers were sold and 303 number of candles were sold.

I have attached the graph below check it out.

Where both the equations of line intersect is our solution thus we can confirm that our answer is correct.
