First you would want to find the length of one eraser and then multiply that by 2. To find the length of one you take the total length or all of them and divide it my the total number of them. 29 1/4 is 117/4.
(117/4) / 13 Dividing by something is the same as multiplying by the opposite.
117/4 × 1/13 = 117/52
Now you multiply by 2.
117/52 * 2/1 Cross simplify
117/26 * 1/1
117/26 inches or 4 1/2 inches.
Answer:
ax+b=r
ax=r-b
x=(r-b)/a
Step-by-step explanation:
5(2x-3) is the factored version
Answer:
<u>1. Yes</u>
<u>2. 83%</u>
<u>Step-by-step explanation:</u>
Does microwaving significantly improve indicators of future breaking?
Yes, this is because the normal requirements based on the 95% confidence implies having a deviation of only 5%. That is, it should fall within 5% of 65 newly baked crackers =5% x 65= 3.25. Thus, since only 3 of the 65 microwaved crackers showed visible cracking we could be confident.
How large is the improvement? What do you conclude about the idea of microwaving crackers?
<em>Approximately there was an 83.08% (57/65 *100 - 3/65 *100) improvement.</em>
The conclusion is that there is a statistically significant relationship between microwaving and reducing cracking.
