Answer:
2x² - 14x + 24
Step-by-step explanation:
Use the FOIL method (First, Outside, Inside, Last).
First, multiply the first term of both parenthesis:
2x * x = 2x²
Next, multiply the outside terms of both parenthesis:
2x * -4 = -8x
Then, multiply the inside terms of both parenthesis:
-6 * x = -6x
Finally, multiply the last terms of both parenthesis:
-6 * -4 = 24
Combine like terms:
2x² - 8x - 6x + 24
2x² (-8x - 6x) + 24
2x² (-14x) + 24
2x² - 14x + 24 is your answer.

Henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. He will get a second turn if he rolls a sum that is an even number less than 10.
What are Henry's chances of getting a second turn when he rolls the number cubes? (2 points)
Answers
Answer:
Step-by-step explanation:
The even numbers less than 10 are
2 which can only be done 1 way: when you roll snake eyes.
4 can be done 3 ways (2,2) (3,1) and (1, 3)
6 can be done 5 ways (2,4) (4,2) (5,1) (1,5) and (3,3)
8 can be done 5 ways (4,4) (2,6)(6,2)(5,3) and (3, 5)
There are 36 ways of throwing the number cubes.
We have a total of 5 + 5 + 3 + 1 = 14 ways

Find the slope of the line that passes through the pair of points
(3,-3), (3,-4)
A undefined
B 0
C -7/6
D -6/7
Answers
Answer:
undefined
Step-by-step explanation:
To find the slope through 2 points
m = ( y2-y1)/(x2-x1)
= ( -4 - -3)/(3 - 3)
= ( -4+3)/(3-3)
= -1/0
Since it is a number divided by zero, the slope is undefined
In the 1990's about 75% of high school graduates attended college. A survey of 2,000 high school graduates was taken in 2018 that showed 1,453 attended college. Do these responses provide strong evidence that the 75% figure is not accurate for current graduates? State the hypothesis and your conclusion using statistical evidence. What does your conclusion mean in context?
Answers
Answer:
These responses do show strong evidence that the 75% figure is accurate for current high school graduates going off to attend college
Step-by-step explanation:
1453/2000 = .7265 or 72.65%
If 1,453 students of a 2,000 student high school attend college after high school, than 72.65% of the students in the high school on average will attend college after they graduate. This percentage compared to the 1990's are a mere 2.35% behind the 75% mark. In this example that is the difference between 1,453 students and 1,500 students. Since these percentages are relatively similar, a conclusion could be made that the 75% mark is an accurate average representation of how many high school graduates will attend college in the future.

Find the 10th term of the geometric sequence 8,-16,32

Answer:
4096
GP = {8 , 16 , 32 , 64 , 128 , 256 , 512 , 1024 , 2048 , 4096...} Therefore , the 10th term of the sequence is 4096.

The required 10th term of the geometric sequence 8, -16, 32 is -4,096.
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
To find the 10th term of the geometric sequence 8, -16, 32, we first need to determine the common ratio (r) between consecutive terms.
r = (second term) / (first term) = (-16) / 8 = -2
So the common ratio is -2.
The nth term of a geometric sequence is given by the formula:
[tex]a_n = a_1 * r^{(n-1)}[/tex]
where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, r is the common ratio, and n is the term number.
To find the 10th term, we plug in a1 = 8, r = -2, and n = 10:
[tex]a_{10} = 8 * (-2)^{(10-1)}a10 = 8 * (-2)^9a_{10} = 8 * (-512)a_{10} = -4,096[/tex]
Therefore, the 10th term of the geometric sequence 8, -16, 32 is -4,096.

A solid sphere is cut into 4 equal wedges the volume of each wedge is v=1/3r3 solve the volume for r
Answers
Answer:
r = (3V/π)^1/3
Step-by-step explanation:
Given that :
Volume of a sphere = V = 4/3πr³
Dividing into 4
4/3 * 1/4 πr³ = 4/12πr³ = 1/3πr³
V = 1/3πr³
Cross multiply
3V = πr³
Divide both sides by π
3V/ π = πr³/ π
3V/ π = r³
Take the cube root of both sides
r = (3V/π)^1/3
