El diámetro de los pernos de una fabrica tiene una distribución normal con una media de 950 mm y una desviación estándar de 10 mm ¿cual es la probabilidad de que un perno escogido al azar tenga un diámetro entre 952 y 957 mm?
ANSWER:
0.178777
Explicación: X = diámetro de los pernos
Te piden:
P(952 < X < 957)
Ahora tienes que estandarizar para usar la tabla de la distribución
P(952 < X < 957)
P 952-950 < X-950 957-950 10 = 10 10
P(0.2 < Z <0.7)
Z~N(0,1)
P(0.2 < Z < 0.7) = (0.7) (0.2) 0.758036-0.579260 0.178777

How much would a 10,000 deposit at five percent annual interest rate for three years earn
Answer:
$1615
Explanation:
A 10,000 deposit at five percent annual interest rate for three years earn 1500.
What is interest?An interest rate indicates how expensive borrowing is or how lucrative saving is.
Therefore, if you are a borrower, the interest rate is the sum you pay for borrowing money and is expressed as a percentage of the overall loan amount.
The fee you pay to borrow money or the fee you charge to lend money is called interest. The most common way to represent interest is as a yearly percentage of the loan amount.
We know that,
Interest = P x R x T
Where,
P = Principal amount (the beginning balance).
R = Interest rate (usually per year, expressed as a decimal).
T = Number of time periods (generally one-year time periods).
Here,
P = 10000
R = 5% = 0.05
T = 3 years
So,
S.I. = 10000 x 0.05 x 3
S.I. = 1500
Thus, the total amount will be 1500.
