Step-by-step explanation:
<h2>using ELIMINATION method</h2>
10x-8y=20
4x+8y=36
14x=56
x=56/14
x=4
<h3>
NOW FOR Y.</h3>
10(4)-8y=20
40-8y=20
-8y=20-40
-8y=-20
y=-20/-8
y=2.5

MARK ME BRAINLIEST PLS!!</h2>
Let the base price be x, cost of tow package be y and cost of hard be z.
So equation for three variables are,
Substract equation x + z = 24890 from equation x + y + z = 25285 to obtain the value of y.
Substract equation x + y = 24290 from x + y + z = 25285 to obtain the value of z.
Substitute the values in the equation x + y +z = 25285 to obtain the value of x.
So base price is $23895, cost of tow package is $395 and cost of hard top is $995.
Answer:
X
Step-by-step explanation:
To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.
To help: draw vertical lines through each graph.
In graph W: the line would pass through the top and bottom of the circle - not a function
In graph X: the line passes once through every area - a function
In graph Y: the line passes through the top curve as well as the bottom curve - not a function
In graph Z: the line passes through the curves multiple times - not a function
Answer:
Out of 1000 people who said that they attend a religious service at least once a week, 31 stopped to help a person with car trouble
Of 1200 people interviewed who had not attended a religious service at least once a month, 22 stopped to help a person with car trouble.
We will use Comparing Two Proportions
i.e. religion service makes no difference
i.e. religion service makes difference
Formula of test statistic :
Substitute the values
test statistic :
Refer the z table for p value
p value = 0.9726
α=0.05
p value >α
So, we failed to reject null hypothesis
Hence religion service makes no difference
Answer:
The height of the trapezoid would be 4 ft.
If you solve this equation,
2*26/5+8 ,
you'll get the answer.
First do the multiplication, then the subtraction, and finally the division.
