This question is incomplete, the complete question is;
In the game of Pick-A-Ball without replacement, there are 10 colored balls: 5 red, 2 white, and 3 blue. The balls have been placed into a small bucket, and the bucket has been shaken thoroughly. You will be asked to reach into the bucket without looking and select 2 balls. Because the bucket has been shaken thoroughly, you can assume that each individual ball is selected at random with equal likelihood of being chosen.
Now, close your eyes! Reach into the bucket, and pick a ball. (Click the red Pick-A-Ball! icon to simulate reaching into the bucket and drawing your ball.)
a) What is the probability of selecting the color of ball that you just selected? (Round your answer to four decimal places.)
Don't put your first ball back into the bucket. Now reach in ( again no peeking ), and pick your second ball. ( Click the red Pick-A-Ball icon to simulate reaching into the bucket and select your next ball.)
b) What is the probability of selecting the color of the ball you selected. ( Enter the answer in decimal format to 4 decimal places ).
Answer:
a) the probability of selecting the color of ball ( RED ) that you just selected is 0.5000
b) the probability of selecting the color of the ball ( BLUE ) I selected is 0.3333
Step-by-step explanation:
Given that;
We have a total of 10 colored balls in a small bucket.
Number of Red balls = 5
Number of White balls = 2
Number of blue balls = 3.
Now, assuming I clicked on the red Pick-A-Ball icon to simulate reaching into the bucket and picking a ball.
Also, Assuming that the color of ball that appeared is Red.
Then the probability of selecting the color of ball ( RED ) that I just selected will be;
P( selected Color ) = Number of Red balls / Total number of balls in the bucket
P( selected Color ) = 5 / 10 = 0.5000
Therefore, the probability of selecting the color of ball ( RED ) that I selected is 0.5000
b)
It is said that the game is Pick-A-Ball without replacement.
So assuming I went on and clicked on the red Pick-A-Ball icon to simulate picking a second ball.
Also, Assuming that the color of ball that appeared was blue.
Then the probability of selecting the color of ball ( BLUE ) that I just selected will be;
P( selected Color ) = Number of Blue balls / Total number of balls in the bucket
Now, since I picked the first ball without replacement, i.e I did not return it back to the bucket, The total number of balls left in the bucket now is 9.
so; P( selected Color ) = 3 / 9 = 0.3333
Therefore, the probability of selecting the color of the ball ( BLUE ) I selected is 0.3333

The table shows the number of points Malik and Alexia scored while playing a video game together. Which equation relates Alexia’s score, a, to Malik’s score, m?
A. a=0.5m
B. a=1.5m
C. a= m+10
D. a=m+30
Answer:
D. a = m + 30
Step-by-step explanation:
It's not A, because that would be dividing Malik's score in half to get Alexia's score.
B only works for the first line.
C is adding 10 to Malik's score, and the difference is greater than that...it's 30 points.

eddie has a steel rod that is 50 inches long. He uses a saw to cut off 2.75-inch pieces from the end of the rod. After cutting off a certain number of pieces, the steel rod is now 36.25 inches long. How many pieces did Eddie cut off the end of the steel rod?
a.) 4 pieces
b.) 5 pieces
c.) 7 pieces
Answer: B. 5 pieces
Step-by-step explanation:
36.25 + 2.75 = 39.00 + 2.75 = 41.75 + 2.75 = 44.50 + 2.75 = 47.25 + 2.75 = 50

Step-by-step explanation:
What is the equation of the line that is perpendicular to line y= -2x+11 and crosses
point (-6, 8)?
y = 1 /2x
y = 1/2x -21
y = 1/2x – 10
y =1/2x + 11
Answer:
[tex]slope \ of \ y = -2x + 11, m_{1} = -2\\\\Let \ the \ slope\ of \ the \ new \ line \ be \ m_{2} \\\\ Since \ the \ line \ is \ perpendicular \ to \ the\ given \ line, m_{1} \cdot m_{2} = -1\\\\-2 \cdot m _{2} = -1\\ \\m _{2} = \frac{1}{2} \\\\Equation \ of \ the \ line \ passing \ through (-6, 8) \ slope = \frac{1}{2} \\\\(y - y_{1}) = m_{2}(x-x_{2} )\\\\(y-8) =\frac{1}{2} (x-(-6))\\\\y -8 =\frac{1}{2} (x+6)\\\\y = \frac{1}{2}x +3 +8\\\\y =\frac{1}{2}x + 11[/tex]

Michelle has 3/5 pounds of sugar. She gave her neighbor some sugar. Now she has 1/2 pounds of sugar left. How much sugar did she give to her neighbor?
Answer: 1/10
Step-by-step explanation:
Answer:
1/10 pound
Step-by-step explanation:
If you set up the equation as 3/5 - 1/2, you'll have to give them a common denominator. Multiply 3/5 by 2 and multiply 1/2 by 5, and now you can rewrite this equation as 6/10 - 5/10. From here, just subtract and you'll get 1/10.

The soup pot is 8 inches tall with a radius of 3 inches.
What is the volume of the soup pot?
150.8 cubic inches
anything
99+
Answer:
The volume of the soup pot is of 226.19 cubic inches.
Step-by-step explanation:
Format of a soup pot:
A soup pot has a cylindrical format.
Cylinder volume:
The volume of a cylinder, with radius r and height g is given by:
[tex]V = \pi r^2h[/tex]
The soup pot is 8 inches tall with a radius of 3 inches.
This means that [tex]h = 8, r = 3[/tex]
What is the volume of the soup pot?
[tex]V = \pi r^2h = \pi*3^2*8 = 72\pi = 72(3.1415...) = 226.19[/tex]
The volume of the soup pot is of 226.19 cubic inches.
f(x) = 3√4x
g(x) = 2x + 3
Find ( f/g) (x). Include any restrictions on the domain
Answer:
B
Step-by-step explanation:
To find [tex](\frac{f}{g} )(x)[/tex] you can write the expression as [tex]\frac{f(x)}{g(x)}[/tex]. We can substitute the f(x) and g(x) into the expression to get: [tex]\frac{\sqrt[3]{4x} }{2x+3}[/tex]. Now we need to find the domain. The numerator is fine, and the domain is all real numbers, but in a fraction, the denominator cannot equal 0. We can write: [tex]2x + 3\neq 0[/tex] and we can solve it:
[tex]2x\neq -3[/tex]
[tex]x\neq -\frac{3}{2}[/tex]
This is the same as option B.
The required function (f/g)(x) is 3√4x/2x+3 where x ≠ -3/2. Option C is correct
Given the functions
f(x) = 3√4x
g(x) = 2x + 3
We are to find the resulting function (f/g)(x)
(f/g)(x) = f(x)/g(x)
(f/g)(x) = 3√4x/2x+3
Restriction to the function occurs at the point where the denominator is zero.
2x = 3 = 0
2x = -3
x = -3/2
Hence the required function (f/g)(x) is 3√4x/2x+3 where x ≠ -3/2

In Oklahoma the state sales tax rate is 7%. If
James purchases a lawn mower at $350.00, then
how much will James pay in state sales tax?
Write 7% as a decimal by dividing by 100:
7/100 = 0.07
Multiple the price of the mower by the decimal:
350 x 0.07 = 24.50
The tax = $24.50
A researcher reported that 71.8% of all email sent in a recent month was spam. A system large corporation believes that the percentage at his company may be 77 % . He manager at a examines a random sample of 500 emails received at an email server, and finds that 361 of the messages are spam.
Required:
Can you conclude that less than 77% of emails are spam?
Answer:
p-value = 0.0054
at 0.05 level of significance ∝
p-value ( 0.0054 ) is less than significance level ∝ ( 0.05 )
Thus we Reject Null hypothesis H₀
Hence, there is enough evidence to conclude that less than 77% of emails are spam.
Step-by-step explanation:
Given the data in the question;
Sample size n = 500
x = 361
p₀ = 77% = 0.77
q₀ = 1 - p₀ = 1 - 0.77 = 0.23
p = x / n = 361 / 500 = 0.722
Hypothesis;
Null hypothesis H₀ : p ≥ 77% or 0.77
Alternative hypothesis Hₐ : p ≥ 77% or 0.77
Test Statistic
z = ( p - p₀ ) / √( ( p₀ × q₀ ) / n )
so we substitute
z = ( 0.722 - 0.77 ) / √( ( 0.77 × 0.23 ) / 500 )
z = -0.048 / √( 0.1771 / 500 )
z = -0.048 / √0.0003542
z = -0.048 / 0.01882
z = -2.55
so our p-value will be;
p-value = p( z < -2.55 ) {from table }
p-value = 0.0054
at 0.05 level of significance ∝
p-value ( 0.0054 ) is less than significance level ∝ ( 0.05 )
Thus we Reject Null hypothesis H₀
Hence, there is enough evidence to conclude that less than 77% of emails are spam.

Answer: [tex]\frac{1}{10}[/tex]
Step-by-step explanation:
First, we need to find the common denominator
The easiest way to do this is by multiplying the two given denominators, which are 2 and 5.
2 × 5 = 10
So, our common denominator is 10. Then, multiply the numerators of the two fractions by 2 and 5. Here's why:
[tex]\frac{3*2}{5*2}[/tex] = [tex]\frac{6}{10}[/tex] We multiplied the top and bottom by 2 to make sure our new fraction stays equivalent to the original fraction.
Do the same thing for the other one:
[tex]\frac{1*5}{2*5}[/tex] = [tex]\frac{5}{10}[/tex]
Finally, subtract the two fractions to find the difference between the two times:
[tex]\frac{6}{10} -\frac{5}{10}[/tex] = [tex]\frac{1}{10}[/tex]
The reason we used the common denominator is because we can only add or subtract fractions if they have the same denominator.
