WILL GIVE BRANLIST Probability Event:
You have a deck of 20 cards numbered 1-20. You draw a card from a deck and keep it. The next person draws another card. What is the probability you will both draw an even card?
Label the probability event above as either
A
Independent
B
Dependent
Answer:
9/38
Step-by-step explanation:
The odds of your drawing an even card from the deck are 10/20, or 1/2. The odds of your friend also taking an even card after (WITHOUT recplacing the card) is 9/19, which cannot be further simplified. You multiply the two -- 1/2 * 9/19 -- which results in your answer, 9/38. This is a dependent probability.

In testing to see whether opinion with respect to the use of instant replay is independent of the category of the person interviewed, a chi-square test statistic of 27.99 and a p-value less than 0.001 were calculated. Which of the following statements is correct?
a. The number of degrees of freedom for the test is 8 - 1 = 7.
b. The chi-square test should not have been used because two of the counts in the table are less than 5.
c. The null hypothesis states that there is an association between category and opinion about the use of instant replay, and the small p-value suggests that the null hypothesis should be rejected.
d. The small p-value suggests that there is evidence of an association between category and opinion about the use of instant replay.
e. The chi-square test shows that fans favor the use of instant replay.
Answer: (D) The small p-value suggests that there is evidence of an association between category and opinion about the use of instant replay.
Step-by-step explanation:
From the P-value supplied, it shows that the researcher was 99% confident of the experiment and have 1% chance of error.
Given that the p-value less than 0.001 were calculated, it translates that there is a statistical dependency between the category of the people interviewed and opinion about the use of instant replay.

Sam and you are going to paint your room together.
Sam takes 10 minutes to paint 25 square feet.
It takes you 5 minutes to paint 25 square feet.
Sam says, "If we paint together, then it will take 15
minutes for us to cover 50 square feet."
Give an explanation to convince Sam that she is
incorrect
Answer:
It takes you together 6.67 minutes to paint 50 square feet, as you have to consider that the together rate is the sum of the separate rates.
Step-by-step explanation:
The together rate is the sum of the separate rates.
In this question:
Sam's rate is 1/10 for 25 square feet, so 1/20 for 50 square feet.
Your's rate is 1/5 for 25 square feet, so 1/10 for 50 square feet.
Together rate:
[tex]\frac{1}{x} = \frac{1}{20} + \frac{1}{10}[/tex]
[tex]\frac{1}{x} = \frac{1}{20} + \frac{2}{20}[/tex]
[tex]\frac{1}{x} = \frac{3}{20}[/tex]
[tex]3x = 20[/tex]
[tex]x = \frac{20}{3} = 6.67[/tex]
It takes you together 6.67 minutes to paint 50 square feet, as you have to consider that the together rate is the sum of the separate rates.

What is the least natural number that is greater than 10 and has a remainder of 5 when divided by 6, has a remainder of 5 when divided by 9, and has a remainder of 5 when divided by 12?
Answer:
41
Step-by-step explanation:
I am essentially going through every multiply of 12 and then adding 5 to it, because we are using the rule that it should have a remainder of 5. It should also be a remainder of 5 if divided by 6 and 9 as well.
12 + 5 = 17
17/6 = 2 R 5
17/9 = 1 R 8
24 + 5 = 29
29/6 = 4 R 5
29/ 9 = 3 R 2
36 + 9 = 41
41/6 = 6 R 5
41/9 = 4 R 5
Hence, the number is 41

What is the Volume of a Rectangle?The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
Let the volume of the rectangular sculpture be V
Now , the value of V = ( 16/21 ) feet³
And , the base area of the rectangular sculpture B = ( 4/5 ) feet²
Volume of Rectangle = Area of Rectangle x Height
On simplifying , we get
The height of the sculpture h = ( 16/21 ) feet³ / ( 4/5 ) feet²
The height of the sculpture h = ( 20/21 ) feet
Therefore , the value of h is ( 20/21 ) feet

For x=4 the functiom f(x) =x2+bx+c has the minimum value of_9.find c
Answer:
[tex]c = 25[/tex]
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a>0, the vertex is a minumum point, that is, the minimum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
In this question:
[tex]a = 1[/tex]
Minimum value at [tex]x = 4[/tex] means that [tex]x_v = 4[/tex]. So
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]4 = -\frac{b}{2}[/tex]
[tex]b = -8[/tex]
So
[tex]f(x) = x^2 - 8x + c[/tex]
Minimum value of 9:
[tex]y_v = 9[/tex]
So
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
[tex]9 = -\frac{\Delta}{4}[/tex]
[tex]-\Delta = 36[/tex]
[tex]\Delta = -36[/tex]
[tex]b^2 - 4ac = -36[/tex]
[tex](-8)^2 - 4c = -36[/tex]
[tex]-4c = -100[/tex]
[tex]4c = 100[/tex]
[tex]c = \frac{100}{4}[/tex]

calculate the gross margin if the selling price is $264 and the cost is $214
Answer:
Gross margin= $50
Step-by-step explanation:
Giving the following information:
Selling price= $264
Unitary cost= $214
To calculate the gross margin, we need to deduct from the selling price the unitary cost:
Gross margin= selling price - unitary cost
Gross margin= 264 - 214
Gross margin= $50

A home-based sign company uses this function to model its monthly profit, where x is the price of each sign it sells.
p(x) = -10x^2 + 498x - 1,500
what is the company's profit if it sells each sign for $20?
A. $18,020
B. $4,460
C. $14,420
D. $1,402
The profit made id each sign is sold for $20 is $4460
The profit model, P(x) = -10x² + 498x - 1,500
Where, x = price per sign sold
If the price per sign sold is $20. Hence, x = $20
The profit made can be calculated thus :
Put x = 20 in the profit function :
P(20) = -10(20)² + 498(20) - 1,500
P(20) = - 10(400) + 9960 - 1500
P(20) = - 4000 + 9960 - 1500
P(20) = $4,460

A recycling company makes $500 per ton of aluminum scrap collected. If the company collects 200 pounds of aluminum scrap per day, how
many days are needed to make $2500? (Tip: One ton equals 2000 pounds).
Answer:
50 days are needed to make $2500.
Step-by-step explanation:
Number of tons per day:
One ton equals 2000 pounds, as the problem states as a hint.
The company collects 200 pounds per day.
1 ton - 2000 pounds
x tons - 200 pounds
2000x = 200
x = 200/2000
x = 0.1
0.1 tons per day.
A recycling company makes $500 per ton of aluminum scrap collected.
0.1*500 = $50 per day.
How many days are needed to make $2500?
1 day - $50
x days - $2500
50x = 2500
x = 250/5
x = 50
50 days are needed to make $2500.

A jar contains five blue marbles and two red marbles. Suppose you choose a marble at random, and do not replace it. Then you choose a second marble. Find the probability of the following even
Both of the selected marbles are red
Answer:
[tex]\frac{1}{21} = 0.0476[/tex] probability that both marbles are red.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Find the probability that both of the selected marbles are red
First marble: 2 red from a set of 5 + 2 = 7
Second marble: 1 red from a set of 6.
So
[tex]p = \frac{2}{7}*\frac{1}{6} = \frac{2}{42} = \frac{1}{21} = 0.0476[/tex]
[tex]\frac{1}{21} = 0.0476[/tex] probability that both marbles are red.
