El producto de dos números consecutivos es 552 cuáles son esos números?
1 answer:
Answer: 23 y 24 ( ó -23 y -24)
Step-by-step explanation:
Two consecutive numbers can be represented as:
n y (n + 1)
where n is an integer.
Hence, "The product of two consecutive numbers is 552" can be expressed as:
n*(n + 1) = 552
n^2 + n = 552
n^2 + n - 552 = 0
We have a quadratic equation, and the possible solutions are obtained using the Bhaskara formula.
The two solutions are:
n = (-1 - 47)/2 = -48/2 = -24
n = (-1 + 47)/2 = 46/2 = 23
If we take the first solution, n = -24
Then the two consecutive numbers would be:
n = -24
(n + 1) = -23
If n = 23, then
n + 1 = 24
Which makes sense, as the only change is the signs, which would negate each other in multiplication.

Answer:
y
y = StartFraction 3 + 6 StartRoot 2 EndRoot Over 4 EndFraction y = StartFraction 3 menos 6 StartRoot 2 EndRoot Over 4 EndFraction
Explicación paso a paso:
La ecuación cuadrática que tenemos es (4y - 3)² = 72
Debemos encontrar el valor de y.
Ahora, 4y - 3 = ± 6√2
⇒ 4y = 3 ± 6√2
⇒ y
Por lo tanto, las soluciones son y = StartFraction 3 + 6 StartRoot 2 EndRoot Over 4 EndFraction y y = StartFraction 3 menos 6 StartRoot 2 EndRoot Over 4 EndFraction (Respuesta)
Answer:
The correct answer is;
A. 0.17
Step-by-step explanation:
Here are the provided details;
The average time taken for a cashier to handle an order, μ = 276 seconds
The deviation from the average, σ = 38 seconds
The z-score for an order processing time of x = 240 seconds can be calculated as follows;
Thus;
The resulting probability
P(z = -0.9474) = 0.17361
Hence, the estimated proportion of orders processed in under 240 seconds is roughly 0.17361 or 0.17 when rounded to two decimal places.
