Answer:
Number 3 is -17 7/24 yards and Number 2 is -42 1/36 meters
Step-by-step explanation:
Number 3:
-7 2/3 + (-9 5/8)
Then you find common denominator.
-7 16/24 + (-9 15/24)
Add.
-16 31/24
Lastly, Simplify.
-17 7/24
Number 2:
-64 7/9 + 22 27/36
Then you find common denominator.
-64 28/36 + 22 27/36
Add.
-42 1/36
Answer:
The probability that the middle school student owns a skateboard or a bicycle is 0.61.
Step-by-step explanation:
We are given that the probability of a middle school student owning a skateboard is 0.58, of owning a bicycle is 0.48, and owning both is 0.45.
A middle school student is chosen at random.
Let the probability of student owning a skateboard = P(S) = 0.58
The probability of student owning a bicycle = P(B) = 0.48
The probability of student owning both = P(S 
B) = 0.45
Now, the probability that the middle school student owns a skateboard or a bicycle is given by = P(S 
B)
P(S B) = P(S) + P(B) - P(S B)
= 0.58 + 0.48 - 0.45
= 0.61
Hence, the probability that the middle school student owns a skateboard or a bicycle is 0.61.
Six Squares, the answer is 36.
5 1/2 pages in 12 minutes.
11/2 pages in 12 minutes
How many pages in an hour?
well, an hour has 60 minutes
Let's write a proportion
11/2 / 12 = x/60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 or 27 1/2 = x
27.5 pages per hour.
Hope this helps
Step-by-step explanation:
arithmetic sequence means every new term is the previous term plus a certain constant.
as we can see, this constant is +4 in our case.
15 + 4 = 19
19 + 4 = 23
23 + 4 = 27
...
so, we have
a1 = 15
a2 = a1 + 4 = 15 + 4 = 19
a3 = a2 + 4 = a1 + 4 + 4 = a1 + 2×4 = 15 + 8 = 23
...
an = an-1 + 4 = a1 + (n-1)×4 = 15 + (n-1)×4
