7 1/8 is greater than 7.025 because if you convert it into a decimal (8 * 7 = 56 + 1 = 57/8 =....) you get 7.125, which is obviously bigger (1>0)

The two inequalities are :

option B and option C

Explanation:

Daniel moves no more than 30 of his sheep and goats into another field. This means the summation of sheep and goats will be at maximum 30.

that is why it is $s+g\leq30$

And more than 7 of his animals are sheep means sheep are greater than 7. that is why = $s>7$

Un depósito se llena de agua a diario para dar de beber a los animales de una granja. Según requerimiento se sacaron 3/8 del agu

Nostrana [21]

Answer:

5/24

Step-by-step explanation:

The question in English is

A tank is filled with water daily to give water to the animals on a farm. As required, 3/8 of the water was taken from the tank to give to the horses and 1/3 of what was left in the tank was given to the pigs. The remainder of the tank was distributed in two equal amounts to give water to the birds and pets. What is the fraction of the water that pets receive to drink?

1) 3/8 of the water was taken from the tank to give to the horses

At this point in the tank there are 1-3/8=5/8 of the water of the tank

2) 1/3 of what was left in the tank was given to the pigs

At this point in the tank there are

(1-1/3)*5/8

(2/3)(5/8)=10/24 of the water of the tank

3) The remainder of the tank was distributed in two equal amounts to give water to the birds and pets

The remainder is equal to 10/24

divided by 2

(10/24)/2=10/48

4) The fraction of the water that pets receive to drink is 10/48

simplify

10/48=5/24

The number of times that students go to the movies per year has mean is a normal distribution with a mean of 17 with standard de

antiseptic1488 [7]

Answer:

53.84% probability that for a group of 10 students, the mean number of times they go to the movies each year is between 14 and 18 times.

Step-by-step explanation:

To solve this problem, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central limit Theorem

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a sample of size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$
