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

Another Eurasian lynx traveled for 301 days. It traveled a distance of 77.8 miles. How many miles per week did it travel
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:
= 301 / 7
= 43 weeks
If it travelled 77.8 miles in 43 weeks, its speed was:
= 77.8 / 43
= 1.8 miles per week
In parallelogram , ABCD ∠A has a measure of 62° . Find the measures of ∠B and ∠C.
Answer:
118
Step-by-step explanation:
If angle A is 62 degrees, then angle D is 62 degrees. 62+62=124, and 360-124 is 236 (360 is the total interior angles of any quadrilateral). Then, 236/2=118. You divide it by two because you are looking for angles B and C separately.
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.
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
Approximately 0.0381

Answer:

Step-by-step explanation:
We need to use the Pythagorean theorem, [tex]a^{2} + b^{2} = c^{2}[/tex].
Substitute in [tex]a[/tex] and [tex]b[/tex].
[tex]30^{2} + 72^{2} = c^{2}[/tex]
Simplify.
[tex]900 + 5184 = c^{2}[/tex]
Add.
[tex]6084 = c^{2}[/tex]
Square root both sides.
[tex]78 = c[/tex]
The hypotenuse is 78 m long.
find c:
a² plus b² = c
72² plus 30²=c
5I84 plus 900

now square root that

<1 and <2 form a linear pair. If m<1= 4m<2, find the measure of each of the two angles.
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°Kyle earned 4 times as much as Ken last summer. If they earned a total of $750, how much did they each earn?
Show all work
(Please help will give brainliest)
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
