Clarise has $290 in her checking account. She writes checks for $102 and $75 and then makes a deposit of $170. Find the amount left in her account. ​

Answer:

Slope = -3

Step-by-step explanation:

The slope is the change in y over the change in x

The slope formula is m=y₂-y₁/x₂-x₁ (y over x)

So, plug in your coordinates (the subscript represents the order in which your points are going to be subtracted in)

So, you would get m=-2-4/1-(-1)

Simplify (first subtract the top, then subtract the bottom)

This would get you to -6/2 (remember your rules: a negative and a negative makes a positive)

-6/2 would get you to -3

-3 is the answer

Answer:

Step-by-step explanation:

The quadratic formula is x = (-b±)/2a when .

Use direct substitution.

x = (-(-4)±)/2(7)

simplify

x = (4±)/14

x = (4±)/14

factor greatest perfect square out of

x = (4±)/14

simplify

x = (4±)/14

greatest common factor

x = (2(2)±)/7(2)

x = (2)(2±)/7(2)

x = (2±)/7

Answer:

This sampling distribution will only reflect the nature of its population distribution (strongly skewed right because the sample size of each sample, 9, is way less than the sample size of 30 required for the sampling distribution to be approximately normal) with mean 404 inches and standarddeviation of sampling distribution equal to 43 inches.

Step-by-step explanation:

The Central limit theorem explains that for an independent, any random set of sample taken from such a population distribution will have a distribution that is approximately normal (provided that the sample size is large enough) with the mean of sampling distribution also approximately equal to the population mean and the standard deviation of the sampling distribution is given as

σₓ = (σ/√n)

where

σ = population standard deviation

n = sample size

To work these out,

Mean of sampling distribution = population mean

μₓ = μ = 404 inches

Standard deviation of the sampling distribution = σₓ = (σ/√n)

σ = population standard deviation = 129 inches

n = sample size = 9

σₓ = (129/√9) = 43 inches.

For most databases, the 'large enough' criteria for the sampling distribution to be approximately normal is a sample size of about 30 and it gets closer as the sample size becomes larger.

The sample size in the question is 9 which is way less than 30, hence, this sampling distribution will only reflect the nature of its population distribution (strongly skewed right) with mean 404 inches and standarddeviation of sampling distribution equal to 43 inches.

Hope this Helps!!!

Answer:answer is D The shape is skewed right but less so than the population distribution.

To solve this problem, you must understand what is the Common Denominator Rule:

The Common Denominator rule is when you use the common factors of the denominators to make them the same number. This will allow you to add and subtract fractions.

First, let’s put these two mixed fractions as improper fractions. Learn more about making that conversion here: brainly.com/question/35061276

Now that you have your fractions, look at the denominators: 6 and 4.

A common factor between 4 and 6 is the number 12. Multiply the denominators and numerators of each fraction by the number that will turn the denominator into 12:

=

=

Now that both factions have the same number in the denominator, you can add them together!
