The ratio in Ryan's science class is 12:10 (girls:boys) which can be simplified to 6:5. In Ryan's 
orchestra group there is a ration of 22:20 which can be simplified to 11:10

11:10 and 6:5 are not the same, therefore the ratio is not equivalent.

Hope this helps :)

The American Automobile Association reported that families planning to travel over the Labor Day weekend would spend an average
Anuta_ua [19.1K]

Answer:

0.7486 = 74.86% probability of family expenses for the weekend being more than $580.

Step-by-step explanation:

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.

The American Automobile Association reported that families planning to travel over the Labor Day weekend would spend an average of $735.

This means that \mu = 735

Assume that the amount spent is normally distributed with a standard deviation of $230.

This means that \sigma = 230

What is the probability of family expenses for the weekend being: a. more than $580

This is 1 subtracted by the pvalue of Z when X = 580. So

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

Z = \frac{580 - 735}{230}

Z = -0.67

Z = -0.67 has a pvalue of 0.2514

1 - 0.2514 = 0.7486

0.7486 = 74.86% probability of family expenses for the weekend being more than $580.

For g(x)= (x+7)^2 + 6x determine the input of x when the output of g(x) =13
AURORKA [14]

Answer:

x = -2 or -18.

Step-by-step explanation:

(x+7)^2 + 6x = 13

x^2 + 14x + 49 + 6x - 13 = 0

x^2 + 20x + 36 = 0

(x + 2)(x + 18) = 0

x = -2, -18.

The following graph of f(x) = x2 has been shifted into the form f(x) = (x − h)2 + k:
Sav [38]
1, the minimum of the function (x-h)^2+k is k, because ()^2 is zero or positive.

The minimum height in the plot is y=1, so that k=1!

How do the graph of the line and the equation of the line in the previous item change if the y-intercept is moved down 3 units?
Paul [167]

Answer:

To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value.
