Taylor had a bag of 28 marbles. 5 red, 9 blue, 8 yellow, and 6 black. If Taylor pulled out a yellow one and DID NOT put it back in. What is the
probability of pulling out a blue marble (SIMPLIFY YOUR FRACTION).
Blank 1:
Blank 2:
Answer: 1/3
Step-by-step explanation:
Number of red marbles = 5
Number of blue marbles = 9
Number of yellow marbles = 8
Number of and black marbles = 6
Total number of marbles = 28
If Taylor pulled out a yellow one and didn't replce it, there'll be 27 marbles left since one has been removed, then the probability of picking blue marbles will be:
= Number of blue marbles / Total marbles
= 9 / 27
= 1/3
The probability of picking a blue marble is 1/3.

If (x - 2)2 + 5(x - 2) = -6, which of the following could be the value of x - 2?
A
-1
B
-3
C
-4
D
-5
Answer: A. -1
Step-by-step explanation:
(x - 2)2 + 5(x - 2) = -6
2x-4 + 5x -10= -6
Combine like terms
7x-14=-6
Add 14 to both sides
7x=8
Divide
X= 8/7 or 1.14 (rounded)
1.14 - 2= -0.86 which can be rounded to -1
A number x added to a number y is equal to 100. The number y is also equal to 10 more than the number x doubled. Write and solve a linear system to find the value of x and y.
Answer: x + y=100---equation 1
y =10+ 2x-----equation 2
x=30, y=70
Step-by-step explanation:
Given that
x added to a number y is equal to 100 which means that
x + y=100
and also that
y is also equal to 10 more than the number x doubled which is
y =10+ 2x
we have the linear systems to solve the equations as
x + y=100---1
y =10+ 2x-----2
Solving
Putting the value of y =10+ 2x in equation 1
x +10+ 2x =100
10+3x=100
3x=100-10
x=90/3=30
x=30
y=10 +2x = 10+2x30 =70

Find the area of the shaded region. The radius of the large circle is 10 m. Round answer to the nearest hundredth.
Answer:
hello the figure related to your question is missing attached below is the missing figure
answer : 157.08 m^2
Step-by-step explanation:
Calculate the area of the shaded area
= Area of the large circle - Areas of the small circles
= (( [tex]\frac{\pi }{4}[/tex] ) * D^2) - 2( ( [tex]\frac{\pi }{4}[/tex] ) * d^2 ) given that the small circles are congruent
= (( [tex]\frac{\pi }{4}[/tex] ) * 20^2 ) - 2 ( ( [tex]\frac{\pi }{4}[/tex] ) * 10^2 )
= 314.16 - 157.08
= 157.08 m^2

explain how your know that 88is a solution to the equation 1/8 R = 11 complete the sentences
The word solution means to
88 is a solution to 1/8 R = 11 because
Answer:
In this equation R would equal 88 because it satisfies the equation.
Step-by-step explanation:
You must solve for R by isolating the variable(which is R). To move the 1/8, multiply both sides by 8. You would do this because 8 is the reciprocal of 1/8. With R on it's own, to keep both sides equal multiply 11*8. That equals 88, which satisfies the equation, which is why 88 is the solution.

The population of village increases by 2% every year. The current population is 1000. What will be the population after 2 years?
Answer:
1040 approx
Step-by-step explanation:
Given data
Rate = 2%
Population= 1000
Time = 2 years
We can apply the expression below to find the population after 2 years
A= P(1+r)^t
Substitute
A= 1000(1+0.02)^2
A=1000(1.02)^2
A=1000*1.0404
A=1040.4
Hence the population is 1040 approx
Last season, Ken made 73% of his free throws. If he attempted 59 free throws all season, estimate how many free throws he made. F 15 H 45 G 38 J 60
Answer:
H 45
Step-by-step explanation:
Given data
Total number of free throws= 59
he made 79%
