Hey there,

This question is asking us to find the slope using the given points. In order to do that we use the equation:

$\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

Now we use the points and plug them into the equation above:

$\frac{(3)-(5)}{(-2)-(-7)}$ = $\frac{-2}{5}$

Therefore the slope of the line that passes through the points (-7, 5) and (-2, 3) would be $-\frac{2}{5}$

Hope I helped,

Amna

A class survey found that 29 students watched television on Monday, 24 on Tuesday, and 25 on Wednesday. Of those who watched TV

gizmo_the_mogwai [7]

Answer:

There were 49 students in the class

Step-by-step explanation:

To solve this problem, we must build the Venn's Diagram of this set.

I am going to say that:

-The set A represents the students that watched TV on Monday

-The set B represents the student that watched TV on Tuesday.

-The set C represents the students that watched TV on Wednesday.

We have that:

$A = a + (A \cap B) + (A \cap C) + (A \cap B \cap C)$

In which a is the number of students that only watched TV on Monday, $A \cap B$ is the number of adults that watched TV both on Monday and Tuesday, $A \cap C$ is the number of students that watched TV both on Monday and Wednesday, and $A \cap B \cap C$ is the number of students that watched TV on every day.

By the same logic, we have:

$B = b + (B \cap C) + (A \cap B) + (A \cap B \cap C)$

$C = c + (A \cap C) + (B \cap C) + (A \cap B \cap C)$

This diagram has the following subsets:

$a,b,c,(A \cap B), (A \cap C), (B \cap C), (A \cap B \cap C)$

The sums of all of this values is the number of student that were there in the class. This means that we want to find the value of T:

$a + b + c + (A \cap B) + (A \cap C) + (B \cap C) + (A \cap B \cap C) = T$

We start finding the values from the intersection of three sets.

Solution:

12 students watched TV on all three days:

$A \cap B \cap C = 12$

14 students watched TV on both Monday and Tuesday

$A \cap B + A \cap B \cap C = 14$

$A \cap B = 14 - 12$

$A \cap B = 2$

Of those who watched TV on only one of these days, 13 choose Monday, 9 chose Tuesday, and 10 chose Wednesday.

$a = 13, b = 9, c = 10$

29 students watched television on Monday:

$A = 29$

$A = a + (A \cap B) + (A \cap C) + (A \cap B \cap C)$

$29 = 13 + 2 + (A \cap C) + 12$

$A \cap C = 29 - 27$

$A \cap C = 2$

24 on Tuesday

$B = 24$

$B = b + (B \cap C) + (A \cap B) + (A \cap B \cap C)$

$24 = 9 + (B \cap C) + 2 + 12$

$B \cap C = 24 - 23$

$B \cap C = 1$

Now we have every value needed to find T:

$T = a + b + c + (A \cap B) + (A \cap C) + (B \cap C) + (A \cap B \cap C)$

$T = 13 + 9 + 10 + 2 + 2 + 1 + 12$

$T = 49$

There were 49 students in the class

Hey!

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

Solution:

= 7√3 + 2√9

= 7√3 + 6

= 18.124... (Non-Terminating or Irrational)

When we add a rational number and a irrational number it's always irrational.

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

Answer:

The answer 7√3 + 6 is irrational because the sum of a rational number and irrational number is an irrational number.

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

M = ______? Please give right answer and no foolish just for points.! I WILL GIVE BRAINLEIST AND A THANKS AND FOLLOW AND 5 STAR

vova2212 [387]

Y = mx + b

Where m is the slope and b is the y-intercept

As you can already see it passes through the origin so b (the y-intercept) is (x, 0)

And the slope were it’s rise/run so it goes up 2.5 units and to the right 1 unit so it’s 2.5/1 = 2.5

m = 2.5

The volume of a mini-basketball is approximately 4846.59 cubic centimeters. What is the approximate radius of a mini-basketball?

Sati [7]

Answer:

10.49823 centimeters

Step-by-step explanation:

Simply reverse the formula for the volume of a sphere: pi*r^3*(4/3).

So: pi*r^3*(4/3)=4846.59

r^3*(4/3)=1542.71751128

r^3*4=4628.15253384

r^3=1157.03813346

r=10.49823
