Select all the correct answers.Which expressions are equivalent to the given expression.
y^-8y^3x^0x^-2

Answers

Answer:

$x^(-2)y^(-5)$

Step-by-step explanation:

The options are not given; however, the question can still be solved

Given

$y^(-8)y^3x^0x^-2$

Required

Simplify

Start by rewriting the expression

$y^(-8) * y^3 * x^0 * x^(-2)$

Apply the following laws of indices: $a^x * a^y = a^(x+y)$

This gives:

$y^(-8+3) * x^(0-2)$

Evaluate the exponents

$y^(-5) * x^(-2)$

$x^(-2)y^(-5)$

Hence, $x^(-2)y^(-5)$ is equivalent to $y^(-8)y^3x^0x^-2$

The expression which is equivalent to the exponential equation is $x^(-2)y^(-5)$ .

Given data:

The exponential form is an easier way of writing repeated multiplication involving base and exponents. It has a base and a power

The exponential form of a number is a way of representing a number using exponents, where the base is typically a number greater than 1.

The exponential expression is represented as $y^(-8)y^(3)x^(0)x^(-2)$ .

From the laws of exponents:

$m^(a)*m^(b)= m^(a+b)$

$(m^(a))/(m^(b))= m^(a-b)$

So, the expression is simplified as:

$y^(-8)y^(3)x^(0)x^(-2)=x^(-2)y^(-5)$

Hence, the equivalent expression is $x^(-2)y^(-5)$ .

What is the largest 4- digit number that is divisible by 3, 6, and 9? Explain how you know.

Answers

Answer: 9990

========================================================

Explanation:

Start with the largest four digit number possible (9999) and see if it's divisible by 3, 6 and 9

9999/3 = 3333
9999/6 = 1666.5
9999/9 = 1111

When dividing the number over 6, we don't get a whole number. So 6 is not a factor of 9999, and we cross 9999 off the list.

------------------------

Decrease the number by 9. We do this because the result will be another multiple of 9 (which is automatically also a multiple of 3 as well, since 9 = 3*3)

So we go from 9999 to 9990

Repeat the last set of steps we did earlier

9990/3 = 3330
9990/6 = 1665
9990/9 = 1110

Every result is a whole number, which shows that 9990 is a multiple of 3, 6 and 9. In other words, 9990 is divisible by 3, 6 and 9. It's the largest such 4 digit number.

Suppose monthly rental prices for a one-bedroom apartment in a large city has a distribution that is skewed to the right with a population mean of $880 and a standard deviation of $50. (a) Suppose a one-bedroom rental listing in this large city is selected at random. What can be said about the probability that the listed rent price will be at least $930?
(b) Suppose a random sample 30 one-bedroom rental listing in this large city will be selected, the rent price will be recorded for each listing, and the sample mean rent price will be computed. What can be said about the probability that the sample mean rent price will be greater than $900?

Answers

Answer:

a) Nothing, beause the distribution of the monthly rental prices are not normal.

b) 1.43% probability that the sample mean rent price will be greater than $900

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:

$Z = (X - \mu)/(\sigma)$

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 $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = (\sigma)/(√(n))$

(a) Suppose a one-bedroom rental listing in this large city is selected at random. What can be said about the probability that the listed rent price will be at least $930?

Nothing, beause the distribution of the monthly rental prices are not normal.

(b) Suppose a random sample 30 one-bedroom rental listing in this large city will be selected, the rent price will be recorded for each listing, and the sample mean rent price will be computed. What can be said about the probability that the sample mean rent price will be greater than $900?

Now we can apply the Central Limit Theorem.

$\mu = 880, \sigma = 50, n = 30, s = (50)/(√(30)) = 9.1287$
