In a study of the television viewing habits of children, a developmental psychologist selects a random sample of 300 first graders - 100 boys and 200 girls. Each child is asked which of the following TV programs they like best: The Lone Ranger, Sesame Street, or the Simpsons.

Complete the following table:

Answer:

0

Step-by-step explanation:

Look at the graph, for x because it is going right continously but it is going towards 0 on the y-axis.

Think of it this way it that line kept going rightward for infinite amounts what would the y value get close to? 0.

In given graph of function, When x → ∞, f(x)=0

Option D is correct.

From the given graph of function,

It is observed that, x- axis is the asymptote of the function.

Since, graph of function never intersect the x- axis.

When x → ∞, f(x)=0

Therefore, option D is correct.

Answer:

35 minutes from 4:12 pm at 4:47 pm the tank will contain only 6617 liters of water.

Step-by-step explanation:

3:56-4:12 = -00:56 minutes passed

10452-8092=2360 liters of water lost

8092-6617=1475 liters

meaning: 56 mins lost 2360L

                x mins lost 1475L

(the 2360 liters lost)/(the 56 minutes during which they were lost) is equal to the rate at which (the 1475 liters would be lost)/(the unknown amount of time)

2360/56 = 1475/x                               (cross multiply)

2360x = 1475(56)                                            

2360x = 82600                                   (simplify)

x = 82600/2360                                  (divide to isolate x)

x = 35                                                    (the unknown amount of time during                             which the water is lost)

4:12 pm plus 35 minutes is 4:47 pm.

The flow rate is the product of the speed of flow and the area through which the fluid flows

The time at which the tank will contain 6,617 L is 4:22 PM

Reason:

Known parameters are;

Volume of water in the tank at 3:56 PM = 10,452 L

Volume of water in the tank at 4:12 PM = 8,092 L

The rate at which water is flowing out of the tank, R, is given as follows;

The flow rate, Q, of water out of the tank, Q = 147.5 L/min

The time it will take tank to contain 6,617 L, is given as follows;

Volume flow out = 10,452 L - 6,617 L = 3,835 L

The time it takes to flow to remain 6,617, t = [tex]\dfrac{3,835}{147.5} = 26[/tex]

It takes 26 minutes from the start before the water remaining is 6,617 L

Therefore, the time of the day, T = 3:56 PM + 26 minutes = 4:22 PM

Answer:

use the formula for a line through two points

[tex]y - y_{1} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \times (x - x_{1})[/tex]

plug in the given points:

[tex]y - 7 = \frac{15 - 7}{5 - 1} \times (x - 1)[/tex]

[tex]y = \frac{8}{4} \times (x - 1) + 7[/tex]

[tex]y = 2 \times (x - 1) + 7 \\ y = 2x - 2 + 7 \\ y = 2x + 5[/tex]

Answer:

112 $ is the original price

Step-by-step explanation:

[tex]x \times 0.75 = 84 \\ x = 84 \div 0.75 \\ x = 112[/tex]

you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale

The value of x in the table above is $112.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given;

All the items on the sale rack were 75 percent off their original price.

Jill bought an item on the sale rack and saved a total of $84

Now,

Let the original price without off be x

84*100/x=75

8400/75=x

x=112

Therefore, the price without 75 percent of will be $112

Answer:

The slope of the line is 8.

Step-by-step explanation:

To solve this problem, we can use the formula for slope:

slope = m = (y2 - y1)/(x2 - x1)

If we substitute in two points from the table into this formula, we get:

slope = m = (11-3)/(1-0) = 8/1 = 8

Therefore, the slope of the line is 8.

We can also see this by looking at the table itself.  Since both x and y are increasing together, we know that the slope should be positive.  For every increase in 1 in x, y increases by 8; this confirms that the slope of the line is 8.

Answer:

Find the exact value using trigonometric identities.

100

Step-by-step explanation:

The exact value of 2 divided by (0.01) 2 is 20000.

We are given that;

2 divided (0.01)2

Now,

To find the exact value of 2 divided by (0.01) 2, we can use the following steps:

Rewrite 0.01 as a fraction: 0.01 = 1/100

Square both the numerator and the denominator: (0.01) 2 = (1/100) 2 = 1/10000

Flip the fraction and multiply by 2: 2 / (0.01) 2 = 2 x 10000/1 = 20000

Therefore, by algebra the answer will be 20000.
