I think of a number, double it and the result is 15

melisa1 [442]

The number in question is 7.5

Step-by-step explanation:

15 ÷ 2 = 7.5

Why divide by 2? Because dividing by 2 is the <u>inverse</u> of multiplying by 2. To double-check our solution, just multiply 7.5 by 2... and 15!!

Sara earns $10 per hour. She wants to make more than $250 in a week. Which inequality represents how many hours Sara must work t

PolarNik [594]

Answer:

A. (10x > 250)

Step-by-step explanation:

more than = > symbol

10 * x number of hours is how much she makes, depending on how many hours she works.

thus, your final inequality is $10 per hour * number of hours she works is greater than (>) 250

10x > 250

In simplest radical form, what are the solutions to the quadratic equation 6 = x2 - 10/?

pickupchik [31]

Answer:

$x = 5 \± \sqrt{31}$

Step-by-step explanation:

Given

$6 = x^2 - 10x$

Required

The solution in radical form

$6 = x^2 - 10x$

Rewrite as:

$x^2 - 10x - 6 = 0$

Using the quadratic formula, we have:

$x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}$

Where

a = 1

b = -10

c = -6

So, we have:

$x = \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*(-6)}}{2*1}$

$x = \frac{10 \± \sqrt{100 +24}}{2*1}$

$x = \frac{10 \± \sqrt{124}}{2}$

Split the roots

$x = \frac{10 \± \sqrt{4 * 31}}{2}$

Express $\sqrt 4$ as 2

$x = \frac{10 \± 2\sqrt{31}}{2}$

Split the fraction

$x = \frac{10}{2} \± \frac{2\sqrt{31}}{2}$

$x = 5 \± \sqrt{31}$

Find the values of the 30th and 90th percentiles of the data. Please show your work.

MaRussiya [10]

Answer:

30th percentile:109

90th percentile: 188

Step-by-step explanation:

The given data set is:

129, 113, 200, 100, 105, 132, 100, 176, 146, 152

We arrange the data set in ascending order to obtain;

Array= $100,100,105,113,129,132,146,176,200$

The 30th percentile is located at

$(\frac{30}{100}\times 10 )}$ -th position, where n=10 is the number of items in the data set

This implies that the 30th percentile is at the 3rd position.

Since 3 is an integer, the 30th percentile is the average of the 3rd and 4th occurrence in the array;

This implies that the 30th percentile = $\frac{105+113}{2}=\frac{218}{2}=109$

The 90th percentile is located at

$(\frac{90}{100}\times 10 )}$ -th position, where n=10 is the number of items in the data set

This implies that the 90th percentile is at the 9th position.

Since 9 is an integer, the 90th percentile is the average of the 9th and 10th occurrence in the array;

This implies that the 90th percentile = $\frac{176+200}{2}=\frac{376}{2}=188$
