Answer:
The radius of the tree trunk is 7 inches.
Step-by-step explanation:
circumference = 2(3.14)radius
43.96 = 2(3.14) r
43.96 = 6.28r
7 = r
Given is:
The total liabilities are $5,000,000 including a loan to expand services.
Net worth at the balance sheet date is given $ 4,000,000.
Hence out of $5,000,000 , $ 4,000,000 is capital and remaining $1,000,000 is loan
Debts to net worth ratio is =
= 0.25 or 25%
Answer:
C
Step-by-step explanation:
(x-8) (x+4) = x^2 - 4x - 32
therefore, x = 8, -4
Answer:
0.78
Step-by-step explanation:
"The probability that a family with 5 children will have at least 2 boys" is equivalent to the complement 1 - P(family will have 1 or 0 boys).
We can use a calculator with statistical functions built in to calculate this probability. The function needed is for binomial probability: binom(n, p, x).
P(family will have 1 or 0 boys) = binomcdf(5, 0.5, {0, 1} ) produces two results: one the probab. of having 0 boys and one the probab. of having 1 boy: 0.03125 and 0.1875. We add these together, obtaining 0.21875.
Then we subtract this result from 1 to obtain The probability that a family with 5 children will have at least 2 boys: 1 - 0.21875 = 0.78125, which may be reasonably rounded off to 0.78.
