Answer:
[tex]x\geq 125[/tex]
Step-by-step explanation:
So first we have to find out the total number of points possibleSo he took 5 tests each with a max score of 100 points, so that's 500 points totalThe final test will be 150 points, so his whole grade is out of 500+150= 650 pointsHe has already scored 460 of those 650 pointsNow how much must he get in the least, on the last test in order to make 90%?Now we need to find what 90% of 650 points isso [tex]\frac{90}{100} *650=\frac{90*650}{100} =585points[/tex] Then we ask ourselves, how much must we add to 460, to get 585 points? 585-460= 125 pointsSo Mark needs to get either 125 points or more on the next test to make 90% or moreNow let's say the letter [tex]x[/tex] means whatever grade number Mark gets on his next testThis number must not be less than 125, so it must be either equal to or greater than 125 pointsSo [tex]x\geq 125[/tex]i will mark you has brainliest if you answer this question
Answer:
Y=X+74
Step-by-step explanation:
75=m+b......*
76=2m+b.........**,b=76-2m
then substitute b=76-2m
on the first equation
75=m+76-2m
m=1
b=74
Y=X+74 is the answer

Write the equation of the line that is parallel to y = -x – 5 and has a y-intercept at (0, 11).
Answer:
[tex]y=-x+11[/tex]
Step-by-step explanation:
We know that the new equation must be parallel to [tex]y=-x-5[/tex].
Therefore, since they are parallel, the slope of the new equation must be the same as the old.
The slope of the original equation is -1.
Therefore, the slope of our new equation is also -1.
We also know that it has a y-intercept at (0, 11).
And as determined earlier, it has a slope of -1.
So, we can use the slope-intercept form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
We will substitute -1 for m and 11 for b. Thus, our equation is:
[tex]y=-x+11[/tex]
Write the slope- intercept form of the equation of each line.

A librarian wants to estimate the percentage of students at his high school who complete their homework each night. Because many students come to the library each morning to study, the librarian surveys the first 40 students who enter. Which type of bias is present, and how does this affect the sample results?
A)There is no bias in this survey because the students were randomly chosen.
B)There is nonresponse bias because the results underestimate the true percentage of students who complete their homework nightly.
C)There is response bias because the results underestimate the true percentage of students who complete their homework nightly.
D)There is convenience sampling bias because the results overestimate the true percentage of students who complete their homework nightly.
E)There is voluntary response bias because the results overestimate the true percentage of students who complete their homework nightly.

5(10k + 1) + 2(2+8k)
Answer:
5(10k + 1) + 2(2+8k)
Use distributive property
5(10k)+5(1)+2(2)+2(8k)
50k+5+4+16k
combine like terms (50k and 16k are alike as well as 5 and 4)
50k+16k and 5+4
66k+9 is the answer

Michael says that 5(153)=5(53). Is his answer correct? Explain. A. Yes; Both expressions are equal to 625. B. Yes; Both expressions are equal to 125⋅ C. No; The first expression is equal to 125 and the second expression is equal to 625. D. No; The first expression is equal to 625 and the second expression is equal to 125.
Answer:
Michael's answer is not correct
5(153)≠ 5(53)
Step-by-step explanation:
Michael says that 5(153)=5(53)
Is his answer correct?
We solve for the left hand side
5(153) = 5 × 153
= 765
Solving for the right hand side
= 5(53) = 5 × 53
= 265
Therefore, from the above calculation,
5(153)≠ 5(53)
5(153) is not equal to 5(53)
Michael's answer is not correct
Find m such that parabola p is completely above the x axis
p↔y = mx^2 + 2x + 1
Answer:
M=-2x+y-1 / x2
Step-by-step explanation:
Solve using substitution.
4x - 5y = 1
x = -6
Answer:
y = -5
Step-by-step explanation:
To solve by using substitution, first substitute x for -6 in the equation 4x-5y=1
4(-6)-5y=1 start by simplifying this problem
-24-5y=1 now you can solve for y, add 24 on both sides
-5y=25 now divide -5 on both sides
y= -5

Traverion wants to find the answer to the question "How much money does the average college professor make?" He surveys 50 professors from the university in his hometown. Which best describes whether or not the results of his survey would represent the responses from the entire population of college professors?
Answer:
The results do not in anyway represent the population reason been that the sample does not represent professors from different areas but only tend to represent 50 professors from his hometown university
Step-by-step explanation:
Based on the information given the results of his survey does not in anyway represent the entire response from the population of college professors reason been the surveys carriedout by him was only for 50 professors from the university in his hometown and not professors from different areas which means that the sample or survey about the amount of money that average college professor make collected by him was not accurate.
Therefore for him to have accurate result he have to survey professors from different area which will inturn give him the accurate sample

The seventh grade enrollment at Goddard increase from 380 to 456 students. What is the percentage of increase?
Answer:
The percentage of increase is minus.
Step-by-step explanation:
Answer:
20%
Step-by-step explanation:
If it increased from 380 to 456, first you need to find the difference.
456 - 380 = 76
Now, you must divide the original number by 76, which is 380.
76/380 = 0.2
Convert 0.2 to a percentage.
0.2 = 20%
The seventh grade enrollment at Goddard increased by 20%.
I hope it all works out well for you in your class :)
