Answer:
A roll of ribbon holds 6.75 meters. A craft club buys 21 rolls.
How many meters of ribbon did the club buy?
What is the total cost if the ribbon sells for $2 per meter?
Step-by-step explanation:
Answer:
Step-by-step explanation:
P = $ 30
r (rate of interest) = 5%
t (no. of years = 2 years
Simple interest = Prt/100
= $3
Answer:
The best deal is the middle one.
Step-by-step explanation:
35.95 with a 20% discount.
You can do this the straight forward way. Take 20% 35.95
20/100 * 35.95 = 7.19
Now subtract this from 35.95
35.95 - 7.19 = 28.76
15/100 * 29.75 = 4.46
29.75 - 4.46 = 25.28
25% * 38.49 = 9.62
38.49 - 9.62 = 28.86
1 mi= 1.6km
1 gal= 3.785
So this means the anwser is 13.6 km/L
Answer:
(a)(B)Yes. This is a legitimate finite probability model because each probability is between 0 and 1 , and all sum to 1 .
(b)P(20‑ to 24‑year‑old who is married)=0.027
(c)P(20–24 year old)=0.26
(d)P(married)=0.398
Step-by-step explanation:
Given the probability model below:
(a)
- Adding the probability for each row, we obtain: 0.227+0.156+0.089+0.054=0.526
- 0.027+0.086+0.137+0.148=0.398
- 0.006+0.015+0.022+0.033=0.076
0.526+0.398+0.076=1
Therefore this is a legitimate finite probability model because each probability is between 0 and 1 , and all sum to 1 .
(b) The probability that the person chosen is a 20‑24-year‑old who is married
P(20‑ to 24‑year‑old who is married)=0.027
(c)Probability that the person chosen is 20 – 24 years old
P(20–24 year old)=0.227+0.027+0.006=0.26
(d)Probability that the person chosen is married
- P(married)=0.027+0.086+0.137+0.148=0.398
