Answer:
19. 5 feets
Step-by-step explanation:
Shadow of tree = 26 feets
Height of flower = 3 feets
Shadow of flower = 4 feets
Height of sun Innthe sky:
Shadow of flower / height of flower
= 4/3 = 1.333333
Height of tree:
Shadow of tree / height of sun
26 feets / 1.33333
= 19.5 feets
Hence, height of tree = 19.5 feets
I'm not sure about part B, but part A will have the answer "if Ron eats lunch today, then he will drink a glass of milk" (without quotes of course)
The idea is that we have these arguments in symbolic form
P = Ron eats lunch today
Q = Ron eats a sandwich
R = Ron will drink a glass of milk
The format is
"If P then Q" ----> "if Q then R" so therefore "If P then R"
We see that P leads to Q, then Q leads to R. So overall P leads to R. We connect them as a chain of sorts. We can skip over Q since we know the first point will lead to the last. Think of it as a shortcut of sorts.
Answer:
$104,710.29
Step-by-step explanation:
The amount is given by ...
A = Pe^(rt)
where P is the principal invested at annual rate r for t years. Filling in the numbers, we get ...
A = 30000e^(.05·25) = 30000e^1.25 ≈ 104,710.29
The balance will be about $104,710.29 on the child's 25th birthday.
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The proportion that live with their parents is 
The sample size is n = 125
Given that there are two possible outcomes and that this outcomes are independent of each other then we can say the Recent census data follows a Binomial distribution
i.e
Now the mean is evaluated as
Generally the proportion that are not staying with parents is
= > 
The standard deviation is mathematically evaluated as
Given the n is large then we can use normal approximation to evaluate the probability as follows
Now applying continuity correction
Generally
So for the z - table
Answer:
D) 7
Step-by-step explanation:
7x280= 1960
1x440= 440
440+1960= 2400
