Part B is not clear and the clear one is;
P(X ≥ 6)
Answer:
A) 0.238
B) 0.478
C) 0.114
Step-by-step explanation:
To solve this, we will make use of binomial probability formula;
P(X = x) = nCx × p^(x)•(1 - p) ^(n - x)
A) 54% of U.S. adults have very little confidence in newspapers. Thus;
p = 0.54
10 random adults are selected. Thus;
P(X = 5) = 10C5 × 0.54^(5) × (1 - 0.54)^(10 - 5)
P(X = 5) = 0.238
B) P(X ≥ 6) = P(6) + P(7) + P(8) + P(9) + P(10)
From online binomial probability calculator, we have;
P(X ≥ 6) = 0.2331 + 0.1564 + 0.0688 + 0.01796 + 0.0021 = 0.47836 ≈ 0.478
C) P(x<4) = P(3) + P(2) + P(1) + P(0)
Again with online binomial probability calculations, we have;
P(x<4) = 0.1141 ≈ 0.114

Answer:
Interest Rate on 2-Year Loan...$435.6
Interest Rate on 5-Year Loan...$1,452
Step-by-step explanation:
The formula for calculating simple interest is as follows.
I = P x R x T,
where I = interest
P= Principal
R= interest rate
T= time
For the loan at 4.5 percent for 2 years, the interest will be
= $4,840 x 4.5/100 x 2
= $4,840 x 0.045 x 2
= $435.6
Total cost of the loan will principal plus interest
=$435.6 + $4,840
=$5,275.6
Monthly loan cost
= $5,275.6/24
=$219.81
Total loan cost..$5,275.6
Monthly loan cost ...$219.81
For the Loan at 6 percent for 5 years, the interest will be
= $4,840 x 6/100 x 5
= $4,840 x 0.06 x 5
=$1,452
Total cost of the loan will be principal plus interest
=$ 4,840 + $1,45
=$6,292
Monthly costs will be
=$6,292/60
=$104.87
Total loan cost... $6,292
Monthly loan costs... $104.87
The first equation tells you that 
. If you substitute this expression for 
in the second, we have
And we can deduce
