Step-by-step explanation:
Everytime she rides the bus 1.25 is taken away from that 20.
The x = Every ride
For example

X=y-8 and -x-y=0 solve by substitution
Answer:
y=4
Step-by-step explanation:
x=y-8
-x-y=0
-(y-8)-y=0
Distribute the negative
-y+8-y=0
Combine the like terms
-2y+8=0
-8 (to both sides)
-2y=-8
Divide by -2
y=4

This year Goran watched movies. He thought that of them were very good. Of the movies he watched, what percentage did he rate as very good?
Answer: 80%
Step-by-step explanation:
Goran watched 55 movies. Out of those movies, he thought 44 were very good.
The question needs to know what percentage this 44 very good movies comprised of the total number of movies.
= Number of very good movies / Total movies * 100%
= 44 / 55 * 100%
= 0.8 * 100%
= 80%
Write the equation of the line passing

y1=-2 y2=5
5+2/-3+4=7
so M=7
y-y1=m(x-x1)
y+2=7(x+4)
2y=7x+28

4y + 4 = 2y - 10
can somebody break this down to solve it ? please
Answer:
y=-7
Step-by-step explanation:
first, you want variables on one side, numbers on the other side of the equation.
4y+4=2y-10
*plus ten on both side to get rid of -10*
4y+14=2y
*minus 4y on each side to get rid of 4y*
14=-2y
*divide by -2 on each side to get the value of just one y itself*
y=-7

A polling firm wants to use a one-sample z interval to estimate what proportion of voters in a country plan on
voting for a certain candidate. They want the margin of error to be no more than £3% at 99% confidence.
What is the smallest sample size required to obtain the desired margin of error?
Answer:
1844
Step-by-step explanation:
For polling firm survey on voters, the smallest sample size which is required to obtain the desired margin of error, is 1850.
What is margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
[tex]MOE=z\times\dfrac{\sigma}{\sqrt{n}}[/tex]
Here, z is the critical value and n is the sample size.
Here, a polling firm wants to use a one-sample z interval to estimate, the number of proportion of voters in a country plan on voting for a certain candidate.
The margin of error for this test is 3% or 0.03 and the confidence interval is 99 percent.
The z value on the confidence interval of 99 percent is 2.576. Here, the standard deviation for this survey is 50 percent, or 0.50.
Put the value in the above formula as,
[tex]0.03=(2.576)\times\dfrac{0.5}{\sqrt{n}}\\n\approx1850[/tex]
Hence, for polling firm survey on voters, the smallest sample size which is required to obtain the desired margin of error, is 1850.
