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.

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.

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.

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

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

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.

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.

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.

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.

Answer: I think Value of x is 8 I’m not sure

Step-by-step explanation:

the right angle is 90 degrees, the line is 180 so 180-90 is 90 so 6X+4 + 5X-2= 90 you can counter the -2 by using the +4 so it just becomes +2 90-2=88 so the answer is 8

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!

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.
