Write and solve an equation to determine the value of x.
​

Answer:

54

Step-by-step explanation:

Find the area of the triangle:

1/2((3 + 5 + 3)*8) = A

1/2((11)*8) = A

1/2(88) = A

44 = A

Find the area of the rectangle:

2 * 5 = A

10 = A

Add the two areas:

10 + 44 = A

A = 54

Answer:

12

Step-by-step explanation:

Brandon's car can go in one gallon gas= 18 miles

In the United States, the gallon is a unit of measurement for liquids such as gasoline, water, and milk. If your car's tank is nearly empty, you should stop and purchase at least a few additional gallons of gas. A gallon of liquid is equal to 4 quarts or 3.785 liters.

Brandon's car used 3/4 of a gallon to travel 13 1/2 miles.

3/4 of a gallon(G)= 13 1/2 miles

3/4*G=27/2

G=18 miles

Hence, Brandon's car can go in one gallon gas= 18 miles.

Step-by-step explanation:

Answer:

A.) 3.096 ; b.) 4 ; C). We reject the Null

D.) There is significant evidence to support the claim that conflict resolution program reduces level of aggression in STUDENTS.

Step-by-step explanation:

This is a paired test:

Given the data:

Before (x) __ After (y) __ difference (x - y)

10 ______ 8 ______ 2

3 _______ 3 ______ 0

4 _______ 1 _______3

8 _______ 5 ______ 3

8 _______ 7 ______ 1

H0 : μx = μy

H1: μx > μy

dbar = Σd / n ; n = sample size

dbar = 9 / 5 = 1.8

From calculator :

Standard deviation of d, Sd = 1.30

Test statistic = dbar ÷ (Sd / √n)

Test statistic = 1.8 ÷0.5813776

Test statistic = 3.096

Pvalue from test statistic :

df = n - 1 = 5 - 1 = 4

Pvalue, 0.05, 4 = 0.018

Since Pvalue < α ; We reject the Null

We conclude that, there is significant evidence to support the claim that conflict resolution program reduces level of aggression in students.

Answer:

Q = 12 meters

Step-by-step explanation:

Since all angles of the triangles are the same, the two triangles are similar. Therefore, all you need to do is a simple comparison equation like 10/15=8/x and solve.

Cross multiply, 10x=120. Divide and get x = 12.

Answer:

510

Step-by-step explanation:

Sally bank account had a beginning balance of 230

She made two deposits of 50 and 420

50+420

= 470

She made a withdrawal of 190

Therefore her balance at the end of the month can be calculated as follows

470+230

= 700

= 700-190

= 510

Hence the balance at the end of the month is 510

On a number line, a number to the right is always greater than a number to its left. Just like 1 is greater than 0, -9 is greater than -11.

-9 > -11

Answer:

First, compute the z-score:

z = (x-μ)/σ = (650-500)/100 = 150/100 = 1.5

Now look up the percentile for z = 1.5 on a z-score table (http://www.z-table.com/).  The percentile, p(z=1.5), is the percent of people who scored 650 or less.  The percent who scored more than 650 is 1-p(z=1.5).  Multiply that by the 1200 students to get the number who scored more than 650.  Round to the nearest whole number (because you can't have a fraction of a person).

For the given data the value of the z score will be 1.5

It is referred to as a measure of data dispersal since it provides information on how widely the data is dispersed.

[tex]\rm \sigma = \sqrt{\dfrac{ \sum (x_i-X)}{n}[/tex]

σ stands for the standard deviation

x  is the value from the data set

X is the data set mean

n is the number of observations

It is given that, On a standardized exam, the scores are normally distributed with a mean of 200 and a standard deviation of 50.

The Z-score of a person who scored 140 on the exam is as,

z = (x-μ)/σ

z = (650-500)/100

z  = 150/100

z  = 1.5

Thus, the value of the z score will be 1.5

Answer:

The equation of line is

[tex]\text{yield}=1.15\times \text{fertilizer}+10.1[/tex]

Step-by-step explanation:

The general equation of line is given as

[tex]y=mx+b[/tex]

where

y is the dependent variable which is yield in this case.

x is the independent variable which is fertilizer in this case

m is the coefficient of the fertilizer whose value is 1.150 from the given values.

b is the constant whole value is 10.100 from the given values.

Thus the equation becomes.

[tex]\text{yield}=1.15\times \text{fertilizer}+10.1[/tex]
