Answer:

4 Blue chips

6 Yellow chips

10 Red chips

Imagine 20% as 2 of 10. We have 20 chips, and that's double of that. So if we have 2/10... we will have 4/20

Same with the yellow chips. Imagine 30% as 3 of 10, again double that... 6/20.

It doesn't directly say the percent of design a computer representation but we can infer that if we have 20% and 30%... that makes 50%, there is only 100 in a percent, so that means there is 50% left! We repeat the process where we envision 50% as 5 of 10, double that. Now we have 10 of 20, 50%!

Answer:

210 minutes

Step-by-step explanation:

First, we want to find out how many meters cubed of water there is, which is the volume.

The volume of this prism would be, the average of the two sides multiplied by 2 and 1.

1.5+0.6 = 2.1

2.1/2 = 1.05

1.05*2=2.1

2.1*1=2.1

2.1 meters is the volume but because it goes down by 30 cm, we have to convert 2.1 to cm.

2.1 * 100 = 210 cm.

Every 30 minutes, it goes down by 30 cm so:

210/30 = 7

210 minutes until it's empty

Answer:

2:1

Step-by-step explanation:

First we convert 3 pounds into ounces which is 3x16 because 1 pound=16 ounces. So 48 ounces=3 pounds. So know we have the ratio 48:24 which we can simplify to 2:1

Hope this helps :)

The required simplest ratio for 3 pounds to 24 ounces is 1 : 8.

Given that,
3 pounds to 24 ounces write each ratio in simplest form is to be determined.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Here,
The ratio of 3 pounds to 24 ounces,
Simplest form = 3 / 24 = 1 / 8.

Thus, the required simplest ratio for 3 pounds to 24 ounces is 1 : 8.

Step-by-step explanation:

There are five dice, so whatever the first die rolls there is a 1/6 chance that the second die is the same number. If that occurs, there's a 1/6 chance that the third die is the same, ditto the fourth and the fifth. So probability of Yahztee in one roll is 1/6 x 1/6 x 1/6 x 1/6 = 1/1296.

Answer: loaded or leading question

Step-by-step explanation:

Loaded or leading questions aim to elicit a particular response from the respondents by including an assumption that makes people feel bad or good if they answer in a certain way. It essentially plays on their emotions and ideals.

The question in the survey is a loaded question because in saying/assuming that the veto will be able to eliminate waste, it makes people more likely to vote in the affirmative as they would want the president to either get rid of waste or would feel bad if they did vote for such an environmental endeavour.

Answer:

(3, 7) is not a solution.

Step-by-step explanation:

In this question, we have to find out if the point (3, 7) is a solution to the equation.

To find your answer, you would plug in the coordinate into the equation and solve.

Solve:

y = 2x - 4

Plug in coordinate.

7 = 2(3) - 4

7 = 6 - 4

7 ≠ 2

Since both sides are not equal to each other, this makes the statement false. Therefore, (3, 7) is not a solution.

Your answer would be (3, 7) is not a solution.

Answer:

No for the first one, yes for the second.

Step-by-step explanation:

Plug in the given numbers and see if it works.

15(1) + 3(4) = 10

15 + 12 = 10.

27 ≠ 10

Since 27 does not equal 10, we can already see that solution (1,4) will not work for these equations.

Now for the second problem, do the same thing.

10 = 1 + 9.

This is true, but remember to check the second equation just to be sure.

10 = 4(1) + 6

10 = 4 + 6

This is also true, so it (1,10) is a solution for the second system of equations.

13 < y + x < 32

Step-by-step explanation:

x in (8,10) and y in (5,22) implies x + y in (8+5,10+22) = (13,32) so 13 < y + x < 32.

Answer:

14 < y+x < 31

Step-by-step explanation:

x = 9

y could be any number from 6 to 21

Answer:

a) [tex]\log_{9} 8 + \log_{9} 11 = \log_{9} 88[/tex]

b) [tex]\log_{7} 11 - \log_{7} 3 = \log_{7} \frac{11}{3}[/tex]

c) [tex]\log_{7}\frac{1}{81} = -4\cdot \log_{7} 3[/tex]

Step-by-step explanation:

Now we proceed to solve each case by appropriate rules for logarithms.

a) The following property shall be used: [tex]\log_{c} a +\log_{c} b = \log_{c} a\cdot b[/tex] ([tex]a = 8[/tex], [tex]b = 11[/tex], [tex]c = 9[/tex])

[tex]\log_{9} 8 + \log_{9} 11 = \log_{9} 8\cdot 11[/tex]

[tex]\log_{9} 8 + \log_{9} 11 = \log_{9} 88[/tex]

b) The following property shall be used: [tex]\log_{c} a - \log_{c} b = \log_{c} \frac{a}{b}[/tex] ([tex]a = 11[/tex], [tex]b = 3[/tex], [tex]c = 7[/tex])

[tex]\log_{7} 11 - \log_{7} 3 = \log_{7} \frac{11}{3}[/tex]

c) The following properties shall be used: [tex]\frac{1}{d} = d^{-1}[/tex], [tex]\log_{c} a^{b}[/tex]

[tex]\log_{7} \frac{1}{81} = \log_{7} 81^{-1}[/tex]

[tex]-\log_{7} 81[/tex]

[tex]-\log_{7} 3^{4}[/tex]

[tex]\log_{7}\frac{1}{81} = -4\cdot \log_{7} 3[/tex]

Answer:

Half of cord 24/2 = 12

Step-by-step explanation:

In the circle with r = 13 we have 13^2 = 12^2 + a^2 where a = the distance from the centre of this circle to the cord. Thus a = 5. Then the distance from the cord to the other circle centre is 21 - 5 = 16. In the second circle you can write r2^2 = 16^2 + 12^2. The r2 = sqrt (400) = 20

Answer:

B. -3d + 47.25

Step-by-step explanation:

Each of them has $15.75

Each spent $d

Amount each still has = 15.75 - d

Therefore, total amount the 3 of them has = 3(15.75 - d) = 3*15.75 - 3*d

= 47.25 - 3d

Which is also am equivalent of -3d + 47.25

Answer:

8.19

Step-by-step explanation:

Adding 5 points to each score in the sample has no effect on the standard deviation. The standard deviation remains the same and constant.

Therefore, the standard deviation for the new sample is 8.19

You can use the fact that standard deviation is a measure of variation.

The standard deviation of the new sample will be same as the old standard deviation, which is 8.19

Standard deviation measures how much the data points vary or disperse from the mean of the data.

The standard deviation is calculated as:

[tex]\sigma = \sqrt{\dfrac{\sum (\overline{x} - x_i)}{n}[/tex]

Since each score was increased by 5 points, we have the mean increased by  5 point too

[tex]\overline{x} = \dfrac{1}{n}\sum(x_i) \\\\x_i -> x_i + 5\\\\\overline{x} = \dfrac{1}{n}\sum(x_i + 5) = \dfrac{5n}{n} + \dfrac{1}{n}\sum(x_i) = 5 + \dfrac{1}{n}\sum(x_i)[/tex]

Putting new mean and new values in the standard deviation formula, we get:

[tex]\sigma = \sqrt{\dfrac{\sum (\overline{x} + 5 - x_i - 5)^2}{n}} = \sqrt{\dfrac{\sum (\overline{x} - x_i)}{n}\\[/tex]

Thus, standard deviation won't change and will stay same as before.

Thus,

The standard deviation of the new sample will be same as the old standard deviation, which is 8.19

Answer:

225 animals

Step-by-step explanation:

From the given information:

[tex]\dfrac{dA}{dt} = ( \dfrac{A}{1125}) (450 - A)[/tex]

[tex]\dfrac{dA}{dt} = \dfrac{450A - A^2}{1125}[/tex]

For a population increasing most rapidly; we have:
