a candy company usually makes bags that have 100 candies in them? Each bag included 25 blue, 30 red, 25 green and 20 orange candies. If you had ten bags of candy in front of you and you reached into each one and grabbed just one candy how many red candies would you expect to have
The expected number of red candy that you will get out of 10 bags is 3 red candies.
How many red candies you would expect to get?
In each bag there are 100 candies, such that there are:
25 blue30 red25 green20 orange.All the candies have the same probability of being randomly selected, so the probability of getting a red candy is equal to the quotient between the number of red candies in each bag and the total number of candy.
P = 30/100 = 0.3
Then if you draw one candy of each bag of 10 bags, the expected number of red candies that you will have is 10 times the above probability:
N = 10*P = 10*0.3 = 3
3 red candies.

Answer:
m∠R = 56°
Step-by-step explanation:
2(8x - 12) = 16x - 24
2(3x + 5) = 6x + 10
16x + 6x + 10 - 24 = 360
22x - 14 = 360
22x = 374
x = 17
3x + 5 = 17 x 3 = 51 + 5 = 56

Find the tangent line approximation to 21/x near x = 21.
21/x≈
Answer:
y = -0.05x + 2.05
Step-by-step explanation:
y = 21/x = 21x^-1
y' = -21x^-2 = -21/x^2
At x = 21 slope = -21/(21)^2 = -0.05 to nearest hundredth.
Tangent line is y - 1 = -0.05(x - 21)
y = -0.05x + 1.05 + 1
y = -0.05x + 2.05
x^2+5y^2+2y=75; dx/dt =14 when x= 6 and y=-3; find dy/dt
Answer:
7
Step-by-step explanation:
x² + 5y² + 2y = 75
2x + 10y * dy/dx + 2 dy/dx = 0
2x + (10y + 2) dy/dx = 0
x + (5y + 1) dy/dx = 0
when x = 6, y = -3
6 + (-15 + 1) dy/dx = 0
6 - 12 dy/dx = 0
dy/dx = 1/2
dy/dt = dy/dx * dx/dt = 1/2 * 14 = 7

4. You are given 20 boxes. 19 of the boxes each have 20 balls weighing 30kg per ball. However, one box has 20 balls weighing 29kg each. All the balls and boxes are identical in appearance. You are asked to determine which box contains the 29kg balls. You have a suitable scale, but may only take a single measurement. No other measurements may be taken (like trying to determine by hand). You may remove balls from the boxes but may still only take one measurement. How can you determine the box with 29kg balls.
To find out the box number the boxes, extract the same number of balls as the number of the box, calculate the total weight.
What are the steps to find the box with the 29 kg balls?Considering you can only weigh the balls extracted once and you need to find the box with balls that are 1-kilo lighter; here are the steps you can follow:
Number the boxes from 1 to 19.Extract the same number of balls as the number given to the box. For example, from box 9 extract 9 balls.Weight all the balls together.Find out the box with the 29 kg balls. Here is an example:The total weight using this method would be 6,300 kg which is the result of adding 30 kg (first box) + 60 kg (second box)... However, since there is a box with lighter balls the total weight will be less.
Let's imagine the weight is 6,290, this means there are 10 fewer kilos and therefore the box with the lighter balls is box 10 since this is the box number from which 10 balls were extracted.

(-1-2a^2b)(1-2a^2b)
Was it this instead? [tex](-1-2a^{2}b)(1-2a^{2}b)[/tex]
Answer:
[tex]4a^{4b}-1[/tex]
Step-by-step explanation:
I am assuming your question is this.
[tex](-1-2a^{2b})(1-2a^{2b})[/tex]
Apply the difference of 2 squares formula.
[tex](a-b)(a+b)=a^{2} -b^{2}[/tex]
So then we have.
[tex](-1-2a^{2b})(1-2a^{2b})=(-2a^{2b})^{2}-1^{2}[/tex]
Then simplify.

Here are scores for two softball teams for seven innings. Rosie's Riveters beat The Susan Bees by how many runs?
here is the score
Answer:
3
Step-by-step explanation:
Rosie's Riveters
1 + 3 + 4 + 2 + 1 + 0 + 2 = 13
Susan Bees
0 + 0 + 5 + 3 + 0 + 1 + 1 = 10
To find out how many they beat the Susan Bees by you need to subtract.
13 - 10 = 3
Rosie's Riveters beat the Susan Bees by 3 runs.

Part D How many of the 320 million Americans would you predict wear CORRECTIVE lenses?
Answer:
320,000,000 * 0.638 = 204,160,000
Step-by-step explanation:
Assuming the sample is a good representation of the people from the United States.
Since there were 1,000 surveyed... and 638 of them were wearing glasses, that makes a proportion of 638 out of 1,000 people, or 63,8 / 100 people... so 63.8%... or 0.638
So, if we assume that the US population is of 320 million, how many people does that make wearing glasses.... we just have to multiply 320M by 0.638
Which is the best estimate for
written in scientific notation?
Answer:
3 x 10^4
(3rd option)
Step-by-step explanation:
8.9 divided by 3.3 is 2.69
8.9 is roughly 9
3.3 is roughly 3
9 divided 3 is 3
10^8 divided 10^4 is 10^4
when dividing numbers with exponents you subtract the exponents
so the best estimate is
3 x 10^4

the product of number is 1 236 if one factor is 103 what is the other factor?
12 or 10 or 9 or 8?
Answer:
The other factor is 12⇒ A
Step-by-step explanation:
The factors of a number are all the numbers multiplied to form this number
Examples:
The factors of 12 are 1, 2, 3, 4, 6, 12 because
1 × 12 = 12
2 × 6 = 12
3 × 4 = 12
∵ The product of numbers = 1236
∵ One factor of that number is 103
∴ ------ × 103 = 1236
→ Divide the number by its factor to find the other number
∴ 1236 ÷ 103 = -------
∵ 123 ÷ 103 = 1 R 20
∵ 206 ÷ 103 = 2
∴ 1236 ÷ 103 = 12
∴ The other factor is 12
