Consider the following scenario:A teacher notices a trend in the students' grades for her midterm exam. Which event probably has the strongest correlation with the exam grades?

The successful completion of the exam review packet
The number of days students ate breakfast that semester
The location of students in the classroom
The number of times students completed extra credit

Answers

Answer 1

Answer: The successful completion of the exam review packet

Answer 2

Answer:

Answer:

The successful completion of the exam review packet

Step-by-step explanation:

This is the only answer that talks about the school work because every other answer doesn’t even correlate with the question. Except the extra credit one but that one still excludes from the original test. Therefore, it is

The successful completion of the exam review packet

Also I got it right on the test

If the width and height of a rectangular prism are each shrunk to one seventh of the original size but the length remains the same, what is the formula to find the modified surface area?

Answers

Hey there,

Let's say 'L'=length, 'W'=width, and 'H'=height.

The surface area of a rectangular prism is

   A = (2LW) + (2WH) + (2LH) = 2 (LW + WH + LH)

If you shrink the width and height, then the new width is W/7
and the new height is H/7.

The new surface area is

   A = (2 L W/7) + (2 W/7 H/7) + (2 L H/7) .

That's    A = 2 (LW/7 + WH/49 + LH/7) .

or you could write it as   A = 2/7 (LW + WH/7 + LH)

There are many more ways to massage the formula and write it
in different ways, but I think writing it just that way is OK.

Which expression is equivalent to n2 + 26n + 88 for all values of n?(n + 8)(n + 11)

(n + 4)(n + 22)

(n + 4)(n + 24)

(n + 8)(n + 18)

Answers

Answer:

Option B is correct.

The expression which is equivalent to $n^2+26n+88$ is; $(n+22)(n+4)$

Explanation:

Given the equation: $n^2+26n+88$ for all values of n.

The quadratic equation in this form; $ax^2+bx+c =0$

First find two numbers that multiply to give ac and add to give b.

From the given equation;

a =1 , b = 26 and c =88

then,

the two number that multiply to give ac =88 is, 22 or 4

and they add up to give b=26 (i.e 22+4)

Now, rewrite the middle term i.e 26n with 22n and 4n , we have

$n^2+22n+4n+88=0$

Now, factor the first two terms and last two terms,

$n(n+22)+4(n+22)$

we see that $(n+22)$ is common to both terms so, we have;

$(n+22)(n+4)$

Therefore, the expression $(n+22)(n+4)$ is equivalent to $n^2+26n+88$

Check:

(n+4)(n+22) = $n\cdot n+ 22n+4n+88$ = $n^2+26n+88$ [ True]

Solutions

The expression equivalent to n^2 + 26n + 88 is

n^2 + 26n + 88
(n + 4)(n + 22)

What is square root of 80 in simplified radical form?A.8 square root over 10

B.10 square root over 8

C.5 square root over 4

D.4 square root over 5

Answers

The number √80 in simplified radical form is 4√5. Therefore, the correct answer is option D.

The given number is √80.

Radical form is the expression that involves radical signs such as square root, cube root, etc instead of using exponents to describe the same entity.

Here, factors of number 80 are 2×2×2×2×5

= √16×5

= 4√5

Therefore, the correct answer is option D.

The graph is a horizontal shift of the function two units to the left.

Given

The graph of the parent squareroot function is;

$\rm y= √(x) +2$

What is the horizontal shift?

The horizontal shift is obtained by determining the change being made to the x-value. The horizontal shift is C.

If the horizontal shift is positive, the shifting moves to the right.

If the horizontal shift is negative, the shifting moves to the left.

The square root parent function is,

$\rm y= √(x) +2$

There is a shift in positive x-direction 2 units.

When the constant is negative the shift is to the right in c units, and when the constant is positive (like in this case) the shift is to the left in c units.

Hence, the graph is a horizontal shift of the function two units to the left.

-3/7, -8/3 and -5/2,-2 slope

Answers

so the points are (-3/7,-8/3) and (-5/2,-2)
to find the slope do
(y2-y1)/(x2-x1)
(x,y)
x1=-3/7
y1=-8/3
x2=-5/2
y2=-2

subsitute
$(-2-( (-8)/(3) ))/( (-5)/(2) - (-3)/(7) )$
simplify by finding similar denomenators
$((-6)/(3)-( (-8)/(3) ))/( (-35)/(14) - (-6)/(14) )$
$((-6)/(3)( (8)/(3) ))/( (-35)/(14) + (6)/(14) )$
add
$((2)/(3))/( (-29)/(14))$
multiply top and bottom by $\frac{-14}{29$
$((-28)/(87))/(1)$
$(-28)/(87)$
answer is
slope= $(-28)/(87)$
