Answer:

1. 2.9

2. 51 inches

3. (if you can send a picture of the question, I can tell you an answer.

Step-by-step explanation:

for number 1:

You have to add the scores on the left and divide it by the total. What I did was multiply each number on the right with it's pair and added it up. I got 111. Afterwards, I totalled the number of students (I got 38) and divided the scores by the number of students to get 2.9.

for number 2:

You do the same thing as number one but instead of multiplying pairs, you add the heights. I got 255 and then divided it by 5 total heights. I got 51 inches.

for number 3: I didn't get the graph to tell you the answer but I can tell you what everything means.

Symmetric means that both sides of the graph are equal and if you fold the graph in half horizontally, you should get the same shape.

Gaps are where you see blanks in the graph where the data gets cut off and then has stats again.

Cluster is when a huge amount of data is gathered in one area.

Peak is where the data (x-axis) reaches it's highest point (highest y-axis point).

Good luck and please give me Brainliest if you liked my answer!

Find the roots of this equation 7xsquare - 5x - 2 = 0

Sophie [7]

Answer:

x = 1, -2/7

Step-by-step explanation:

You could use the quadratic equation but this can be factored into

(7x + 2) (x - 1). You can verify that by multiplying it out.

Since (7x + 2) (x - 1) = 0, if either factor is 0 then the equation would be equal to 0, thus we get x = 1, -2/7

PLEASE HELP WILL MARK BRAINLIEST

Answer: Choice D

b greater-than 3 and StartFraction 2 over 15 EndFraction

In other words,

b > 3 & 2/15

or

$b > 3\frac{2}{15}\\\\$

========================================================

Explanation:

Let's convert the mixed number 2 & 3/5 into an improper fraction.

We'll use the rule

a & b/c = (a*c + b)/c

In this case, a = 2, b = 3, c = 5

So,

a & b/c = (a*c + b)/c

2 & 3/5 = (2*5 + 3)/5

2 & 3/5 = (10 + 3)/5

2 & 3/5 = 13/5

The inequality $2 \frac{3}{5} < b - \frac{8}{15}\\\\$ is the same as $\frac{13}{5} < b - \frac{8}{15}\\\\$

---------------------

Let's multiply both sides by 15 to clear out the fractions

$\frac{13}{5} < b - \frac{8}{15}\\\\15*\frac{13}{5} < 15*\left(b - \frac{8}{15}\right)\\\\39 < 15b-8\\\\$

---------------------

Now isolate the variable b

$39 < 15b-8\\\\15b-8 > 39\\\\15b > 39+8\\\\15b > 47\\\\b > \frac{47}{15}\\\\b > \frac{45+2}{15}\\\\b > \frac{45}{15}+\frac{2}{15}\\\\b > 3+\frac{2}{15}\\\\b > 3\frac{2}{15}\\\\$

Side note: Another way to go from 47/15 to 3 & 2/15 is to notice how

47/15 = 3 remainder 2

The 3 is the whole part while 2 helps form the fractional part. The denominator stays at 15 the whole time.

Answer:

1

Step-by-step explanation:

identify two points on the graph:

1. (0, 4)

2. (-2, 2)

use slope formula: (y² - y¹) / (x² - x¹)

1. (2 - 4) / (-2 - 0) = -2 / -2 = 1

slope = 1

Are these two lines perpendicular?

lys-0071 [83]

Answer:

Step-by-step explanation:

This is the image of the graph you determine if that's perpendicular.

Perpendicular definition - In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle. The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
