Answer:

s = independent variable, P(s) = dependent variable

Step-by-step explanation:

s = discrete because you need a certain value for shirts. For instance, 1,2,3, etc... you cannot make profit off half a shirt or a quarter of a shirt.

P(s) = continuous because profits doesnt have to be an exact value. For instance, you can make a profit of $12.65

Answer:

1,280

Step-by-step explanation:

prob(spots) = 12/180 = 1/15

so of the 1200 frogs, (1/15)(1200) should have spots, so ..

how many should not have frogs ?

or

prob(not spots) = 14/15

number who don't have spots = (14/15)(1200) = 1,280

x = 7

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

7x - 6 = 8 + 5x

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 43 does indeed equal 43.

∴ x = 7 is a solution of the equation.

Answer

7(7x)-6=8+5(7x)

49-6=8+35

43=43

2c+10=30

2c+10−10=30−10

2c=20

2c÷2=20÷2

Answer: c=10

Answer:

10

Step-by-step explanation:

2c + 10 = 30

so we take 10 to the other side to become - 10.

Therefore 2c = 30 - 10

= 20

Divide both sides by the coefficient of c that's 2

2c = 20

c = 10

Tip Total: $ 12

Total (Bill + Tip): $ 92

Sorry if this is wrong

Step-by-step explanation:

Answer:

$12 tip

Step-by-step explanation:

For this problem let's first round our bill amount to the nearest ten dollars.  So $79.42 becomes $80.00.  From here we will simply need to find 15% of $80.00 which can be found simply through multiplication as follows:

$80.00 * 0.15 = ?

$80.00 * 0.15 = 12

So, we can say the estimated 15% tip for the bill is $12.

Cheers.

Answer:

The equation y=4x-1 has a greater rate of change

Step-by-step explanation:

to find rate of change for the table, you use [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

so, [tex]\frac{-5-(-7)}{-2-(-3)}[/tex] =      [tex]\frac{2}{1}[/tex]  = 2

So the rate of change for the table is 2 while the rate of change for the equation is 4. 4>2 so the equation has a greater rate of change.

Answer:

The answer would be $40.

Step-by-step explanation:

You take the first 25% off and add it to the other 25% off, which would equal 50% off. After that you take 50% off for $80, which would be $40 because half of $80 is $40.

Answer:

  A)  28

Step-by-step explanation:

Of the seven moves, 3 must be to the left, and 4 must be to the right. That is, we end up exactly one space right of where we started, so there must be exactly one more move to the right than to the left.

The number of permutations of LLLRRRR is 7!/(4!·3!) = 35. Of those, several must be eliminated, because they result in a path that goes off the right side of the board.

The discounted sequences are ...

With these 7 possibilities eliminated from the list, there are 35 -7 = 28 possible paths from P to Q.

Answer:

P_he = 562.5 mmHg

P_ne = 1068.75 mmHg

P_ar = 618.75 mmHg

Step-by-step explanation:

Formula for partial pressure is;

Partial pressure = mole fraction × total pressure

Mole fraction of Helium(He); x_he= 1/(1 + 1.9 + 1.1) = 1/4 = 0.25

Mole fraction of Neon(Ne); x_ne = 1.9/(1 + 1.9 + 1.1) = 1.9/4 = 0.475

Mole fraction of argon; x_ar = 1.1/(1 + 1.9 + 1.1) = 1.1/4 = 0.275

Thus;

Partial pressure of He;

P_he = 0.25 × 2250

P_he = 562.5 mmHg

Partial pressure of Ne;

P_ne = 0.475 × 2250

P_ne = 1068.75 mmHg

Partial pressure of Ar;

P_ar = 0.275 × 2250

P_ar = 618.75 mmHg

Answer:

$600

Step-by-step explanation:

first, you need to find the unit price which is found by dividing 720 by 6.

so, 720/6 is 120

then, to find the cost of 5 notebooks, you just need to multiply 120 by 5

which would get you 600.

therefore, the total cost of 5 notebooks is $600.

i hope that helps :)

Answer:

600

Divide 720 from 6

= 120

120 x 5 = 600

Answer:

The height of the prism is 5 inches

Step-by-step explanation:

The rule of the lateral area of the rectangular prism is

L.A = 2(L + W) × H, where

∵ A rectangular prism has a length of 9 inches and a width of 8 inches

∴ L = 9 inches

∴ W = 8 inches

∵ The lateral area of it is 170 square inches

∴ L.A = 170 square inches

→ Substitute them in the rule above to find the height of the prism

∵ 170 = 2(9 + 8) × H

∴ 170 = 2(17) × 5

∴ 170 = 34 × H

→ Divide both sides by 34 to find H

∴ 5 = H

∴ The height of the prism is 5 inches.

0.9

Step-by-step explanation:

The average age of the lizards will be 2 and the standard deviation is 0.81.

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values.

Given that the lizards were randomly selected from the 36 lizards at your local zoo: 1, 2, 2, 1, 3, 3

The average will be calculated as:-

Average = Sum of the data / Number of the data

Average = ( 1 + 2 + 1 + 3 + 3 ) / 6 = 12 / 6 = 2

The standard deviation will be calculated as:-

[tex]\rm \sigma=\sqrt{\dfrac{\sum(x-\mu)^2}{N}}\\\\\sigma=\sqrt{\dfrac{(1-2)^2+(2-2)^2+(1-2)^2+(3-2)^2+(3-2)^2}6[/tex]

[tex]\sigma[/tex] = 0.81

Therefore, the average age of the lizards will be 2 and the standard deviation is 0.81.

Step-by-step explanation:

1. You have a ladder that is 10 feet tall and you place it on the ground 6 feet away from your house, which you plan to paint. How far up will the ladder reach? (Ans: 8 feet)

2. I think drawing a diagram of this is pretty self-explanitory. Just remember to lable the ladder as 10 feet, the ground as 6 feet, and the house as 8 feet.

3. There wasn't really an equation in the question, but if you draw a triangle you'll need to solve for the third side. It would be 8 feet, but if you consider the pythagoran therom:

100ft(c^2, the hypotenuse, or the ladder)- 36 ft(a^2, or the ground)= 64, the square root of 64 would give you 8. You can write it out symbolically, but I'm typing and there's not much I can do on here.

I'm not really sure what the question is here, because you just gave a statement... but if you are trying to get an expression from words, here is what it would be:

A = 10N

I'm also not sure if "a number" is equal to the same as "a number" at the end, but I'm guessing not. If it is though, and you're trying to find the value of A, the answer would be:

A = 10

Answer:

10$

Step-by-step explanation:

i think is 1 dollars because if u multiply 25 by 40% it will give you ur answer wait till someone else answers

Ashley got $10 discount, at 40% discount on the meal worth $25.

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

Given that,

The cost of meal = $25.00

The discount given to Ashley on meal = 40%

The total value of discount = 25 x 40/100

                                             = 1000/100

                                             = 10

The total discount given by shopkeeper is $10.
