Answer:

-3x + 40

Step-by-step explanation:

The constant given is 40 gallons and the rate at which the water in the bathtub decreases is 3 gallons per minute.

To write this as an equation we model 40 as the starting constant that is positive and, because the water is decreasing, we use a negative slope.

-3x represents the decrease in water over x intervals (Which in this case is minutes) and 40 gallons represent the initial value (water in the bathtub).

Therefore the water in the bathtub can be modeled with the equation

-3x + 40

Step-by-step explanation:

Given:

Total sample n = 200

Yield x = 35

Confidence level = 90%

Find:

Proportion non-conforming

Computation:

Proportion p = x / n

Proportion p = 35 / 200 = 0.175

Non Proportion q = 1 - p

Non Proportion q = 0.825

So,

z value of 90% is 1.64

So,

Proportion non-conforming

p ± [z√pq/n]

0.175 ± [1.64√(0.175)(0.825)/200

Answer:

47.1 cm

Step-by-step explanation:

The circumference of a circle is denoted by C = 2πr, where r is the radius.

Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:

C = 2πr

C = 2 * 3.14 * 7.5 = 47.1

To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.

Thus, the circumference is 47.1 cm.

Step-by-step explanation:

Answer:

x = -84, y = -58

Step-by-step explanation:

2x - 3y = 6 --- Equation 1

Equation 1×5: 10x - 15y = 30 --- Equation 2

5x + 7y = -14 --- Equation 3

Equation 3×2: 10x + 14y = -28 --- Equation 4

I will eliminate 10x.

Equation 4-2:

10x - 15y - 10x + 14y = 30-(-28)

-y = 30+28

   = 58

y = -58

Substitute y  =-58 into Equation 1.

2x - 3y = 6

2x - 3(-58) = 6

2x - (-174) = 6

2x + 174 = 6

Find 2x.

2x = 6-174

    = -168

Find x.

x = -168 ÷ 2

x = -84

Step-by-step explanation:

Answer:

this is the correct answer 4/3

Answer:

There will be 18 grams left after 12 hours.

Step-by-step explanation:

Half-life is the amount of time it take for a cell to turn from one condition to another.

To find the amount of grams for the first 6 hours.

72 ÷ 2= 36

Now, since 6 x 2 = 12, we need to divide 36 by 2 to find the next half-life.

36 ÷ 2 = 18

Therefore, there will be 18 grams left after 12 hours.

Hope this helps! :D

Complete question is;

Elle Measured the height of a plant, in inches,Every week for four weeks after planting it.

The height of the plant, h, in inches, Can be modeled by the function h(t) = 1.5t + 3, where t represents the time in weeks.

Based on this model, what is the best prediction for the height of the plant after 12 weeks?

A 16.5 inches

B 21 inches

C 22.5 inches

D 27.3 inches

Answer:

Option B: 21 inches

Step-by-step explanation:

We are given the function h(t) = 1.5t + 3, where t represents the time in weeks.

At t = 0;

h(0): 1.5(0) + 3 = 3inches

At t = 1;

h(1): 1.5(1) + 3 = 4.5 inches

Thus, after 12 weeks, height will be;

h(12): 1.5(12) + 3 = 21 inches

Option B is correct

Answer:

1/3/4 are all correct

Step-by-step explanation:

For Paul to select 1 of his 4 children, the simulation tool must have the possibility of giving a result of 1/4 (i.e. 1 in 4 children). The simulation tools capable of these results are: (1), (3) and (4)

To determine which simulation tool is correct for the situation, we simply put each option to test.

Option (1)

[tex]Sections = 12[/tex]

[tex]Sub= 3[/tex]

Here, the simulation is done by calculating the probability of each subsection.

The probability is:

[tex]Pr = \frac{Sub}{Sections}[/tex]

[tex]Pr = \frac{3}{12}[/tex]

Simplify

[tex]Pr = \frac{1}{4}[/tex]

Option 2

[tex]Chips =12[/tex]

[tex]Sections = 2[/tex]

Here, the simulation is done by calculating the probability of each section.

The probability is:

[tex]Pr = \frac{Sections}{Chips}[/tex]

[tex]Pr = \frac{2}{12}[/tex]

Simplify

[tex]Pr = \frac{1}{6}[/tex]

Option 3

A standard deck has:

[tex]Cards = 52[/tex]

[tex]Suit = 13[/tex]

Here, the simulation is done by calculating the probability of each suit.

The probability is:

[tex]Pr = \frac{Suits}{Cards}[/tex]

[tex]Pr = \frac{13}{52}[/tex]

Simplify

[tex]Pr = \frac{1}{4}[/tex]

Option 4

[tex]Coins = 2[/tex]

Here, he needs to toss the coin 2 times. So, the possible sample space are:

[tex]S = \{HH, HT, TH, TT\}[/tex]

The probability of one of the outcomes is:

[tex]Pr = \frac{1}{n(S)}[/tex]

Where:

[tex]n(S) = 4[/tex] ---- number of outcomes

So:

[tex]Pr =\frac{1}{4}[/tex]

Option 5:

[tex]Sides =6[/tex]

The probability of getting 1 of the 6 faces is:

[tex]Pr = \frac{1}{6}[/tex]

Paul can only use simulations that give 1/4. Hence, (1), (3) and (4) are correct because they all equal 1/4.

Step-by-step explanation:

Answer:

1. Couples tickets: $8

   Individual tickets: $4

2. Song download cost: $2

    Movie download cost: $15

Step-by-step explanation:

You can solve both of these questions by doing system of equations.

Let's start with question 1.

There are 2 variables in this equation:

- Couples tickets price: let's represent these with the letter C

- Individual tickets price: let's represent these with the letter K

Writing the two equations would look this these:

5c + 2k = 48

3c + 2k = 32

Next, isolate a variable. I am going to isolate K in the first equation.

[tex]2k = -5c + 48 \\k = -\frac{5}{2}c + 24[/tex]

Now that we isolated a variable we can plug that back in to the second equation:

[tex]3c + 2(-\frac{5}{2}c + 24) = 32\\3c - \frac{10}{2}c + 48 = 32\\3c -5c + 48 = 32\\-2c + 48 = 32\\-2c = -16\\c = 8[/tex]

We found that c is equal to 8 so we can put that back in to an equation to solve for k.

5(8) + 2k = 48

40 + 2k = 48

2k = 8

k = 4

Therefore, the price for couples tickets is $8 and the price for individual tickets is $4.

Check #1:

5(8) + 2(4) = 48

40 + 8 = 48

48 = 48

3(8) + 2(4) = 32

24 + 8 = 32

32 + 32

Now, let's go on to question 2.

There are 2 variables in this equation:

- Price of songs downloaded: let's represent these with S

- Price of movies downloaded: let's represent these with M

Writing the two equations would look like this:

15s + 11m = 195

15s + 8m = 150

There is a simple way to answer this system, however.

If you change the bottom equations signs to negative you can minus the second equation from the first equation like this:

15s + 11m = 195

-(15s +8m = 150)

Minus them to get this equation:

3m = 45

Solve

m = 15

We have found that each movie download costs $15, now let's plug this back into an equation:

15s + 11(15) = 195

15s + 165 = 195

15s = 30

s = 2

Each song costs $2 to download.

Check #2:

15(2) + 11(15) = 195

30 + 165 = 195

195 = 195

15(2) + 8(15) = 150

30 + 120 = 150

150 = 150

I hope this helps!!
