Answer:
Guarantee of Tyre = 36,680 miles
Step-by-step explanation:
Given:
Mean = 46,000 miles
Standard deviation = 4,000 miles
Computation:
Assume;
x = guaranteed lifetime
P(X > x) = 99%
So,
P(X > x) = 0.99
So,
P(Z > z) = 0.99
So,
1 - P(Z > z ) = P(Z < z)
P(Z < z) = 0.01
So, in z table value of z = -2.33
x = μ + [z x σ]
x = 46,000 + [-2.33 x 4000]
x = 36,680
Guarantee of Tyre = 36,680 miles
Answer: 4600
Step-by-step explanation:
Jack divided his fortune of 92,000 into 8 equal parts. This means a part will be equal to:
(92000 ÷ 8) = 11500.
He gave 4 parts to his wife. This means his wife has:
(11500 × 4) = 46000.
1 part to his son means that his son has: (1 × 11500) = 115000.
He gave the last 3 parts and evenly it among 5 charities. This means:
(3 × 11500) = 34500 was shared among 5 charities. Each charity will get: (34500 ÷ 5) = 6900
To calculate how much more money did his son get than the charities will be:
11500 - 6900 = 4600
