there are 6 boys and 5 girls in the debate class. kids are being selected to go present their work without getting opt-out where is the probability that a boy will be selected to present twice?

Answers

Answer:

30%?

Step-by-step explanation:

6 boys, 5 girls

first selection is a 6/11 chance it's a boy.

second seletion is a 6/11 chance it's a boy.

6/11 times 6/11 is... 0.2975 or about a 30% chance ( i think)

Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.

Over the summer, the facility manager of a public swimming pool collected information on the amount of water in the pool and the number of swimmers. The results are shown in the scatter plot below. Which statement is supported by the data in the scatter plot?

A. As the number of swimmers increases, the amount of water in the pool tends to decrease.

B. As the number of swimmers increases, the amount of water in the pool tends to increase.

C. As the number of swimmers increases, the amount of water in the pool tends to stay the same.

D. There is no relationship between the number of swimmers and the amount of water in the pool.

Answers

The answers is B

Step-by-step explanation:

EDGE2021

As the number of swimmers increases, the amount of water in the pool tends to decrease.

Thus, option (A) is correct.

Given:

A scatter plot which shows he amount of water in the pool and the number of swimmers.

Now, from the scatter plot it can be seen that

As the number of swimmer increases there is no such change in amount of water.

There is only increase in a amount of water when the number of swimmers were between 60 to 70.

But at last the plot shows that the amount of water decrease.

Therefore, number of swimmers increases, the amount of water decrease.

Thus, option (A) is correct.

Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15

Answers

Answer:

Roots are : 1, -7 and -7

Step-by-step explanation:

When we put x = -1 in F(x) it is equal to 0

Thus, (x + 1) is factor of given function.

When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)

factorizing the work x² - 6x - 7 by middle term splitting.

> x² - 6x - 7 = x² - 7x + x - 7

> x(x - 7) + 1(x - 7)

> (x + 1) (x - 7)

then, x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)

x = -1, -1, 7 the factor.

Can someone please help me figure out how to solve this?

Answers

Answer:

B. 48m²

Step-by-step explanation:

The formula for volume is length (base) times width times height, or LWH. If you break the shape into three separate areas, you can figure out the volume for each part and then add it up.

The large part on the bottom is 7m long, 2m across. Since we know the entire shape is 4m tall and the indent is 2m deep, we know that the height for the bottom part will also be 2m. 7 · 2 · 2 = 28.

The block on the left is 2m tall, 2m across, and its width is also 2m as shown by the measurement on the bottom-right. 2 · 2 · 2 = 8.

Finally, the block on the right is 2m tall, 3m across, with a width of 2m. 3 · 2 · 2 = 12. And when you add it all up, 28 + 8 + 12 = 48. Hope this helps! Feel free to ask any questions!

Use the given line of best fit to approximate the rate of change relative to the scatter plot below.

A. 1/20 errors per word translated

B. 1/5 errors per word translated

C. 1/10 errors per word translated

D. 3/20 errors per word translated

Answers

Answer:

C. 1/10 errors per word translated

Step-by-step explanation:

According to this graph, we can see that every 100 words-translated, there are about 10 errors (red line). The red line continues at this slope/ratio, and so it would be 10/100 or 1/10 simplified.

The rate of change relative to the scatter plot below will be 1/10 errors per word translated. Option C is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

For the given condition, we have to find the rate of change relative to the scatters plot below.

The given graph is in between the total error and the translation error. This graph shows that there are around 10 translation mistakes for every 100 words (red line). Given that the red line continues at this slope and ratio, it would be expressed as 10/100 or 1/10.

Thus, the rate of change relative to the scatter plot below will be 1/10 errors per word translated. Option C is correct.

Truman is buying a teddy bear and flowers for his girIfriend. Flowers Galore charges $13 for the teddy bear and $0.75 per flower. Famous Florist charges $9 for the teddy bear and $1.25 per flower. Which inequality represents the number of flowers, f, Truman would need to buy to make Flowers Galore the cheaper option?

Answers

the answers is either f < 2 or f > 2

The inequality that would make Flowers Galore the cheaper option is 13 + 0.75f < 9 + 1.25f

How to determine the inequality?

At Flowers Galore, we have:

Teddy bear = $13

Flower = $0.75

At Famous Florist, we have:

Teddy bear = $9

Flower = $1.25

So, the expressions are:

Flowers Galore: 13 + 0.75f

Famous Florist: 9 + 1.25f

When Flowers Galore is the cheaper option, we have:

13 + 0.75f < 9 + 1.25f

Hence, the inequality that would make Flowers Galore the cheaper option is 13 + 0.75f < 9 + 1.25f

How many mg of a metal containing 38 percent nickel must be combined with 5 mg of pure nickel to form an alloy containing 68 percent nickel? Which of the following equations could be used to solve this?

Answers

Answer:

the Answer is C

Step-by-step explanation:

The metal needs to be 16/3 mg in weight to get the required alloy.

We can use the third equation,

(a(0.38) + 5(1.00))/(a+5) = 68/100

to solve the problem.

What do we mean by Percentage?

A percentage is a ratio where a number is shown as a fraction with respect to 100 parts of it. To remove the percentage sign we divide the number by 100.

How do we solve the given problem?

We are asked to mix a certain quantity of metal in mg containing 38 percent of nickel to 5 mg of pure nickel such that the new alloy contains 68 percent of nickel.

Let the quantity of metal taken to be 'a' mg.

∴ Nickel provided by the metal is 38% of a,

or, (38/100)*a

or, a(0.38)

We took 5 mg of pure nickel so it is 100 percent pure,

∴ Nickel in the alloy from pure nickel = 100% of 5

or, (100/100)*5

or, 5(1.00)

Total weight of the alloy = a + 5

Total nickel in the alloy = a(0.38) + 5(1.00)

We are said that the alloy constitutes 68 percent of nickel,

∴ (a(0.38) + 5(1.00))/(a+5) = 68%

or, (a(0.38) + 5(1.00))/(a+5) = 68/100

This is the equation needed to find the quantity of metal used to make the alloy. It is the same as option 3.

On solving the equation we get that the required quantity of the metal is 16/3 mg.
