What is the slope of the line that passes through (-4,2) and (6,-8)
Answer:
y = x + -2
Step-by-step explanation:
I know you're probably asleep but here's the answer. And I'm 14 years old, so I might be young and undereducated.
(-4,2) and (6,-8)
-8-2 = -10
6 -(-4) = 10 (-10/10 = -1)
-8 = 6(-1) + b
-8 = -6 + b
-2 = b

Which of the following segments is a diameter of o
O?
Answer: A
Step-by-step explanation:
The segment passes through the center of the circle, O, and its endpoints lie on the circumference of the circle.
The segment ZX is the diameter of the circle O. Then the correct option is A.
What is a circle?It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The diameter of the circle is the longest chord that is passing through the center of the circle.
The segment ZX is the diameter of the circle O.
Then the correct option is A.

What is the y intercept and slope hurry please
From the given graph , we see that it passes through the point (0,-1) .
Hence the y intercept is -1 .→ y intercept = -1
For finding slope , take another point as (1,3) . Now using the points (1,3) and (0,-1) we can find out the slope as ,
→ m = y2 - y1 / x2 - x1
Substituting the respective values,
→ m = 3 -(-1)/1-0
→ m = 3+1/1
→ m = 4/1
→ m = 4
Hence the slope of the line is 4 and its y intercept is -1 .

Step-by-step explanation:
A student is about to take a true-false, 5-question quiz, with absolutely no knowledge of the subject. So, the student flips a coin to determine their response to each question. If you let the random variable X = "a number of correct answers on the quiz," what is the correct histogram?
Answers are from 1-4, and they are all in order.
Using the binomial distribution, considering the probability of each event, the correct histogram is the fourth one.
For each question, there are only two possible outcomes, either the student guesses the correct answer, or not. The probability of guessing the correct answer on a question is independent of any other question, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
There are questions, hence n = 5.They are true-false questions, that is, they have one correct option out of 2, hence p = 0.5.Then, the probabilities are as follows:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{5,0}.(0.5)^{0}.(0.5)^{5} = 0.03125[/tex]
[tex]P(X = 1) = C_{5,1}.(0.5)^{1}.(0.5)^{4} = 0.15625[/tex]
[tex]P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.3125[/tex]
[tex]P(X = 3) = C_{5,3}.(0.5)^{3}.(0.5)^{2} = 0.3125[/tex]
[tex]P(X = 4) = C_{5,4}.(0.5)^{4}.(0.5)^{1} = 0.15625[/tex]
[tex]P(X = 5) = C_{5,5}.(0.5)^{5}.(0.5)^{0} = 0.03125[/tex]
Hence the fourth histogram is correct.

What is the solution to this equation -8x - 40 = 8
The answer is -6 :)
1. Add 40 to both sides of the equation.
-8x-40=8
-8x-40+40=8+40
2. Add the numbers.
-8x=48
3. Divide both sides of the equation by the same term.
-8x=48
[tex]\frac{-8x}{-8}[/tex]=[tex]\frac{48}{-8}[/tex]
4. Cancel terms that are in both the numerator and denominator and divide the numbers.

There are 110 sixth-grade students in a Florida
middle school. 40% of the students enjoy playing
video games on the weekends. Using the percent
as a rate per 100, how many students enjoy
playing video games?
Answer:
44 students play video games
Step-by-step explanation:
110*0.40 = 44
i hope this helps! have a wonderful rest of ur day :)
Answer:
40/100
Step-by-step explanation:
40% of 110 is 44 so we make this a fraction 44/110 and then simplify to get 2/5 and after that we know that 2/5 is also 40/100, meaning 40 out of 100 students like video games.

Answer:
ok so we want to find out 30% of 300 is
so first lets turn it into its decmil form by multiplying by 0.01 so
30*0.01=0.3
then lets multiply that by 300 so
300*0.3=90

Find the range of possible values for x.
Answer:
x is between 5 and 33 ⇒ 5 < x < 33Step-by-step explanation:
The two triangles have two equal side measures:
4 units and the sides marked as equal,The third side is different and the given angles are opposite them.
It means the angle measure 4x - 20 is smaller than 112:
4x - 20 < 1124x < 132x < 132/4x < 33On the other hand, the angle measure is positive:
4x - 20 > 04x > 20x > 5So the possible range of x is:
5 < x < 33First it must be positive
4x-20>04(x-5)>0x-5>0x>5And
4x-20<1124x<132x<33So solution range

75% of what number is 15? make it so clear pls pls
20 is the answer.
Step-by-step explanation:
Take a look at the given question,
"75% of what number is 15"
Let's substitute this "what number" as "x"
[tex]75[/tex]%[tex] \times x = 15[/tex]
[tex]→x = \frac{15}{75 \: percent} [/tex]
[tex]→x = \frac{15}{ \frac{75}{100} } [/tex]
[tex]→x = \frac{15}{0.75} [/tex]
To make the denominator as positive for making calculations more easy, we get,
[tex]x = \frac{15 \times 100}{0.75 \times 100} [/tex]
[tex]→x = \frac{1500}{75} [/tex]
Now after doing the division, we get,
[tex]x = 20[/tex]
Hence, 75% of 20 is 15.
