Mathematics
1 answer:
bezimeni [28]3 years ago
6 0

Answer:

5^x - 5^-x

Step-by-step explanation:

g(x) = 5^-x

h(x) = 5^x

We want h(x) - g(x)

h(x) - g(x) = 5^x - 5^-x

This cannot be simplified

For the high school basketball game, it cost's $ 12 for every 3 tickets.
sineoko [7]

Answer:

<u>Cost in US$          =  12 - 16 - 24 - 36 - 40</u>

<u>Number of tickets =  3  - 4 -   6 - 9 - 10</u>

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

For a high school basketball game, it cost's US$ 12 for every 3 tickets.

It means that every ticket costs US$ 4 (12/3 = 4)

2. Let's complete the table below:

<u>Cost in US$          =  12 - 16 - 24 - 36 - 40</u>

<u>Number of tickets =  3  - 4 -   6 - 9 - 10</u>

For  US$ 16 = 4 * 4

For US$ 24 = 6 * 4

For US$ 36 = 9 * 4

For US$ 40 = 10 * 4

Note: Same answer than question 14016273, answered  by me.

Jumbo eggs in Australia, on average, are supposed to weigh 68g. Margot is in charge of a quality control test that involves weig
Andrej [43]

Answer:

0.9987 = 99.87% probability that the mean weight of 4 eggs in a package is less than 68.5g

Step-by-step explanation:

To solve this question, we use the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be 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}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean weight of 67g and a sample standard deviation of 1g.

This means that \mu = 67, \sigma = 1

Sample of 4

This means that n = 4, s = \frac{1}{\sqrt{4}} = 0.5

What is the probability that the mean weight of 4 eggs in a package is less than 68.5g?

This is the pvalue of Z when X = 68.5. So

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

By the Central Limit Theorem

Z = \frac{X - \mu}{s}

Z = \frac{68.5 - 67}{0.5}

Z = 3

Z = 3 has a pvalue of 0.9987

0.9987 = 99.87% probability that the mean weight of 4 eggs in a package is less than 68.5g

????????????????vbzjjzjdvdu
Romashka-Z-Leto [24]

Answer:

A

Step-by-step explanation:

There is an empty dot on 4, meaning b is not equal to 4.

The arrow is going to the left of 4, so it means that b is less that four.

Hope that helps!
