To decrease an amount, you would multiply it by 0.30. you multiply it by 0.30 because this gives you 30%; therefore, it has been decreased by 70%. To decrease an amount, you always times it by 0. and then whatever the remainder is. If you were decreasing 'y' by 65%, you would work it out by doing y * 0.35

Henry counted 350 Lockers in his school Hailey counted 403 Lockers in her school how does the 3in 350 compared to the three in 4
stiv31 [10]
The 3 in 350 represents 300

because 350=300+50+0, that is: 3 one hundreds +5 tens +0 ones


The 3 in 403, represents 3 because 403 = 400+3 that is 4 one hundreds, 0 tens and 3 ones.


Thus the 3 in the number 350 and  the 3 in the number 403 are not the same.

The 3 in the number 350 is one hundred time the 3 in the number 403.


Answer: The 3 in the number 350 is one hundred time the 3 in the number 403.

Assume that the GMAT scores across the U.S. follow a bell shaped distribution (symmetric and unimodal) with mean 549 and standar
blondinia [14]

Answer:

The GMAT score corresponding to the 16th percentile is 473.

Step-by-step explanation:

Empirical Rule.

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

68% of the measures within 1 standard deviation of the mean.

This means that they are between the 50 - (68/2) = 50 - 34 = 16th percentile(one standard deviation below the mean) and the 50 + (68/2) = 50 + 34 = 84th percentile(one standard deviation above the mean).

In this question:

Mean of 549, standard deviation of 76.

16th percentile:

One standard deviation below the mean, so 549 - 76 = 473.

The GMAT score corresponding to the 16th percentile is 473.

Is the relationship shown by the data linear? If so, model the data with an equation.
Harrizon [31]
The <u>correct answer</u> is:

The relationship is linear, and the equation is 
y-5 = 2(x+7).

Explanation:

To determine if the relationship is linear, we find the slope between each pair of points.  Slope is given by the formula:

m=\frac{y_2-y_1}{x_2-x_1}

The slope between the <u>first two points</u> is given by:

m=\frac{9-5}{-5--7}=\frac{9-5}{-5+7}=\frac{4}{2}=2

The slope between the <u>second pair of points</u> is given by:

m=\frac{13-9}{-3--5}=\frac{13-9}{-3+5}=\frac{4}{2}=2

The slope between the <u>third pair of points</u> is given by:

m=\frac{17-13}{-1--3}=\frac{17-13}{-1+3}=\frac{4}{2}=2

Since the <u>slope is the same</u> throughout the data, the <u>relationship is linear</u> and the slope is 2.

To write the equation, we use point-slope form, which is:

y-y₁ = m(x-x₁)

Using the first point, we have:

y-5 = 2(x--7)
y-5 = 2(x+7)
