Which is the graph of the system of inequalities

Leni [432]

Answer:

A

Step-by-step explanation:

Try testing each graph by picking a point on the shaded region or none shaded region.

-1/5 and 6= y-intercept

4/5 and 2= slope

You may notice that it is in y-intercept form. So to find where the shaded region goes, test a coordinate and apply it to the equation, if the answer is false, than half of the line is not where the shaded region goes.

The 2010 U.S. Census asked every household to report information on each person living there. Suppose for a sample of 30 househo

Maslowich

Answer:

$\bar x =2.53$ -- Mean

$Median= 2$

$Mode = 2$

$Range = 8$

$Q_1 = 1$

$Q_3 = 3$

$IQR = 2$

Step-by-step explanation:

Given

n = 30

Data: 2 3 1 2 6 4 2 1 5 3 2 3 1 2 2 1 3 1 2 2 4 2 1 2 9 3 2 1 1 3

Solving (a): The mean

This is calculated as:

$\bar x =\frac{\sum x}{n}$

$\bar x =\frac{2 +3 +1 +2 +6 +4 +2 +1 +5 +3 +2 +3+ 1+ 2 +2 +1 +3 +1 +2 +2 +4 +2 +1 +2 +9 +3 +2 +1 +1 +3}{30}$

$\bar x =\frac{76}{30}$

$\bar x =2.53$

Solving (b): The median

First arrange the given data

Arranged: 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 4 4 5 6 9

$Median =\frac{1}{2}(n+1)$

$Median =\frac{1}{2}(30+1)$

$Median =\frac{1}{2}(31)$

$Median = 15.5th$

This implies that the median is the average of the 15th and 16th item

$Median = \frac{2+2}{2}$

$Median = \frac{4}{2}$

$Median= 2$

Solving (c): The mode

From the given data; 2 has the highest frequency of 11.

So,

$Mode = 2$

Solving (d): The Range

$Range = Highest\ Data - Lowest\ Data$

The highest is 9 and the lowest is 1,

So:

$Range = 9 - 1$

$Range = 8$

Solving (e): Lower (Q1) and Upper (Q3) quartile.

Q1 is calculated as:

$Q_1 = \frac{1}{4}(n+1)th$

$Q_1 = \frac{1}{4}(30+1)th$

$Q_1 = \frac{1}{4}(31)th$

$Q_1 = 7.75th$

$Q_1 = 8th\ item$

$Q_1 = 1$ -- from the arranged data

Q3 is calculated as:

$Q_3 = \frac{3}{4}(n+1)th$

$Q_3 = \frac{3}{4}(30+1)th$

$Q_3 = \frac{3}{4}(31)th$

$Q_3 = 23.25th$

$Q_3 = 23rd\ item$

$Q_3 = 3$ -- from the arranged data

Solving (f): The interquartile range (IQR)

$IQR = Q_3 - Q_1$

$IQR = 3-1$

$IQR = 2$

Mr. Rose spent $63 for a sport jacket and a pair of slacks. If the jacket cost $33 more than the slacks, how much did he pay for

zloy xaker [14]

The equation would be j+s=total
we know that the total is 63, and the jacket cost s+33
it is addition and subtraction, so we can cancel the last one. j is more than s, so we would go with your second option, <span>j + s = 63 and j - s = 33.
