Answer:
0.06 = 6% probability of landing open side up.
0.14 = 14% probability of landing closed side up.
0.8 = 80% probability of landing on its side.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. For an experimental probability, these numbers are taken from previous trials.
Landing open side up:
3 out of 50, so:
0.06 = 6% probability of landing open side up.
Landing closed side up:
7 out of 50, so:
0.14 = 14% probability of landing closed side up.
Landing on its side:
40 out of 50, so:
0.8 = 80% probability of landing on its side.
The number of pages in the book is actually irrelevant.
Franco reads 30 pages in 1 night. To find how many pages he reads in 7 nights, just multiply by 7.
30*7=210
Franco reads 210 pages in 7 nights.
Solving with Equivalent Ratios:
The ratio of pages he reads per night is 30:1. We need to figure out the ratio <em>x</em>:7, where the variable <em>x</em> is the number of pages he reads in 7 nights.
30:1=<em>x</em>:7
To find x we need to see the similarity between both ratios. This is found by dividing two of the equal sides, here it would be 7 and 1.
7/1=7
This means that the second ratio is 7 times the first ration. To find <em>x</em>, just multiply 30 by 7.
30*7=210
Franco reads 210 pages every 7 nights.
The answers are x=4 and y=323/2
1) 40/2x-3=8
Multiply both sides by 2x-3 to get rid of fraction
40= 8(2x-3)
Distribute 8
40= 16x-24
Add 24 to both sides
64=16x
Divide by 16
4=x
2) 2y-3/40=8
Multiply both sides by 40 to red rod of fraction
2y-3=320
Add 3 to both sides
2y= 323
Divide by 2
Y=323/2
Now just describe the differences in solving them
FYI / means fraction, right after the slash is bottom of fraction
Answer:
(a) the interest is $6384
Hope this helps!
Answer:
C) $877.50
Step-by-step explanation:
Time t = 4 years
Principal, p = $750
rate, r = 4.25% = 0.0425
Amount that will be in her account in four years =
Simple interest (prt/100) + principal
750 * 4.25* 4 / 100 + 750
127.5 + 750
= $877.50
