Find is the value of x.*

Find the number that makes the ratio equivalent to 2:6.<br><br> 8:

Citrus2011 [14]

A ratio is used to describe how two or more quantities are related. For example, we might say that a fruit drink calls for sugar crystals to be mixed with water in a ratio of 2:6. This means that for every 2 scoops sugar crystals, there will need to be 6 ounces of water. If there were 200 scoops of sugar crystals, there would need to be 600 ounces of water.

[find the area please explain steps]

Length of base of the top triangle = 23 inches

Length of height of the top triangle = 47 inches

Area of the top triangle :

$= \frac{1}{2} \: \times \: base \: \times \: height$

$= \frac{1}{2} \times 23 \times 47$

$= \frac{1}{2} \times 1081$

$= \frac{1081}{2}$

$= \color{hotpink} \: 540.5 \: \:sq. inches \:$

Thus, area of the top triangle = 540.5 sq.inches

Length of base of the bottom triangle = 47 inches

Length of height of the bottom triangle = 46 inches

Area of the bottom triangle :

$= \frac{1}{2} \: \times \: base \: \times height$

$= \frac{1}{2} \times 47 \times 46$

$= \frac{1}{2} \times 2162$

$= \color{hotpink}1081 \:sq. inches$

Area of the bottom triangle = 1081 sq.inches

Area of the total figure :

= Area of top triangle + Area of bottom triangle

$= 540.5 + 1081$

$= \color{hotpink}\bold{1621.5 \: \: sq.inches}$

Therefore, the area of the figure = 1621.5 sq.inches

Suppose that the distribution for total amounts spent by students vacationing for a week in Florida is normally distributed with

Charra [1.4K]

Answer:

96.24% probability that a SRS of 25 students will spend an average of between 600 and 700 dollars

Step-by-step explanation:

To solve this question, 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 normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
