Show all work
(Please help will give brainliest)
Answers
Answer:
600, 150
Step-by-step explanation:
Kyle is x
ken is y
x = 4y
x+y = 750
replace x with 4y
4y + y = 750
5y = 750
y = 150
so ken earned 150
x + 150 = 750
x = 600
so Kyle earned 600

What is the area of circle?The region that a circle occupies in a two-dimensional space is known as the area of the circle.
The area of circle is -
A = πr²
Given:
The chemistry teacher decides to use chalk paint to cover a circular portion of a wall in the science lab.
If the greatest distance across the circle is is 3 feet.
We can write the maximum area covered as -
A = πr²
A = 3.14 x 3 x 3
A = 9 ft² {approx.}
So, the maximum area covered will be 9 ft².

<1 and <2 form a linear pair. If m<1= 4m<2, find the measure of each of the two angles.
Answers
Answer:
The angle ∠1 = x = 36°The angle ∠2 = 4x = 4(36°) = 144°Step-by-step explanation:
We know that when two lines meet or intersect, we get a linear pair of angles.
Linear pairs are basically two adjacent angles that form a line.
The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.
We are given that <1 and <2 forms a linear pair, and
m∠1 = 4m∠2
It means the angle ∠1 is 4 times the measure of angle ∠2.
Let the angle ∠1 be = x
As the angle 1 is 4 times the measure of angle ∠2, so
The angle 2 will be = 4x
As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so
x + 4x = 180
5x = 180
divide both sides by 5
5x/5 = 180/5
x = 36°
Therefore,
The angle ∠1 = x = 36°The angle ∠2 = 4x = 4(36°) = 144°Post 3 things you Notice or 3 things you Wonder about this image

a jar contains 6 red jelly beans, 6 green beans, and 6 blue jelly beans if we choose a jelly bean, then another jelly bean without putting the first one back in the jar, what is the probability that the first jelly bean will be green and the second will be green as well
Answers
======================================================
Explanation:
We have 6 green out of 6+6+6 = 18 total
The probability of getting green is 6/18 = 1/3.
After selecting that green jelly bean and not putting it back, we have 6-1 = 5 green out of 18-1 = 17 total.
The probability of selecting another green is 5/17.
Multiply the two fractions 1/3 and 5/17
(1/3)*(5/17) = (1*5)/(3*17) = 5/51
The probability of selecting two greens in a row is 5/51 where we do not put the first selection back. We also do not replace the green jelly bean with some other identical copy.
Note: 5/51 = 0.098039 approximately

Answers
Answer: 1.8 miles per week
Step-by-step explanation:
The European lynx travelled for 301 days and in that time covered a distance of 77.8 miles.
Convert the number of days to weeks:

= 43 weeks
If it travelled 77.8 miles in 43 weeks, its speed was:

Answers
Multiply .90 (90 percent) by 600 (total points all semester) to see how many points she must earn. You’ll get 540.
Add the scores she’s got already and subtract from 540.
I get 439. She needs 540 and the most she could possibly make is 539.

10% of electric light bulbs are defective at manufacturer. A random sample of 8 light bulbs are chosen and tested. Find the probability that at least 3 are defective.
Answers
Answer:
0.0381
Step-by-step explanation:
This is a binomial probability distribution problem. Thus;
p = 10% = 0.1
We are told that A random sample of 8 light bulbs are chosen and tested. Thus, n = 8
We want to find the probability that at least 3 are defective. This will be;
P(X ≥ 3) = P(3) + P(4) + P(5) + P(6) + P(7) + P(8)
P(X = x) = C(n, x) × p^(x) × (1 - p)^(n - x)
Thus;
P(3) = C(8, 3) × 0.1³ × (1 - 0.1)^(8 - 3)
P(3) = C(8, 3) × 0.1³ × 0.9^(5)
P(3) = 0.03306744
Repeating this same procedure, we have;
P(4) = 0.0045927
P(5) = 0.00040824
P(6) = 0.00002268
P(7) = 0.00000072
P(8) = 0.00000001
Thus;
P(X ≥ 3) = 0.03306744 + 0.0045927 + 0.00040824 + 0.00002268 + 0.00000072 + 0.00000001 = 0.03809179
