Answer:
Constanza ocupará, como mínimo, para forrar la caja:
1350 cm²
para forrar la caja
Step-by-step explanation:
En un cubo cada una de las aristas que lo conforman miden lo mismo.
Un cubo tiene 6 caras.
La formula del área del área de las 6 caras del cubo es:
área total del cubo = a = 6*arista²
en este caso:
a = 6*(15cm)²
a = 6 * 225 cm²
a = 1350 cm²
54/-2 = -27
First, let's rewrite:
Let x represent the unknown number:
Hence, 54/-2 = -27
Answer:
So this is giving us the slope the slope is y=-7x+150
Step-by-step explanation:
It is giving us the Y intercept which is $150 because thats how much he starts out with
It is giving us the slope -7 dollars because he is spending that everyday
Answer:
1.6 hours

you divide 11.2 by 7

Answer:
A: The 10 percent condition states that the population is greater than 10 times the sample, or 10n. In other words, the sample size must be no more than 10 percent of the population. In this problem, the sample size is 7, and the population is 38. This means that 38>10n, or 38>10 times 7, or 70. 38 is not greater than 70, therefor the 10 percent condition is not met in this case.
B: In this problem, p, or the population proportion is 14/38. The conditions of normality are that n times p and n times 1-p are both greater than 5. n=38 and p, as stated, equals 14/38. This means that n times p equals 14, and n times 1 minus p equals 24, which are both greater than 5. This means that both of the normality condition have been met.
