Answer:
hi
Step-by-step explanation:
first of all,we should do this:
1 year is 12 month
amd 4 year is 48 month(12×4)
then we must add 2 months (wich is given) to 48
He was 50 months old when he started school
and we should find how old is he now
11 ×12=132months
132+1=133months
133-50=83 ( he has been 83 months in school)
let's turn it to years 6 years 11 months
( for finding years you should divide 83 to 12)
hope it helps
Answer:
The probability that the cost is kept within budget or the campaign will increase sales is 0.88
Step-by-step explanation:
The probability that the cost is kept within budget (event A) <u>or</u> the campaign will increase sales (event B) is the <u>union</u> of the probability of those two events. By basic properties of probability, this is:
P(A ∪ B) = P(A) + P (B) - P(A ∩ B)
and for independent events:
P(A ∩ B) = P(A) * P(B)
So:
P(A ∪ B) = 0.80 + 0.40 - (0.80*0.40) = 1.20 - 0.32 = 0.88
answer to the problem is x=2/3
Answer:
The equation which expresses the ratio of the circumference to the diameter of a circle is 
⇒ D
Step-by-step explanation:
π is the ratio between the circumference of the circle and the length of its diameter
, where
- C is the circumference of the circle
- d is the diameter of the circle
∵ The circumference of the circle is C
∵ The radius of the circle is 15 units
∴ r = 15 units
- Find the diameter of the circle
∵ The diameter of the circle d = 2 r
∴ d = 2(15) = 30 units
∴ The diameter of the circle is 30 units
∵
∵ d = 30 units
∴
The equation which expresses the ratio of the circumference to the diameter of a circle is
