I Sally buys 5 dolls and 1 purse for $21.
Donna buys 7 dolls and 1  purse for 27$

From the result that we have here the total number of grey wolves is given as 32

To estimate the population of the grey wolves in the Northern Rockies, we need to find the average number of tagged grey wolves in each sample of 20 and use that as a estimate for the population.

The mean number of tagged wolves in the five samples is:

(1 + 2 + 2 + 1 + 2) / 5 = 8 / 5 = 1.6

This means that, on average, 1.6 wolves out of 20 have a tag. We can use this information to estimate the total population of the grey wolves in the Northern Rockies:

(1.6 tagged wolves per sample of 20) * (total number of grey wolves / 20) = total number of tagged grey wolves

Multiplying both sides of the equation by 20, we find:

total number of grey wolves = (1.6 tagged wolves per sample of 20) * 20 = 32 grey wolves

So, we estimate that there are approximately 32 grey wolves in the Northern Rockies.

To estimate the number of classmates who do not belong to a major political party, we can use the proportion of students in the sample who do not belong to a major political party as a basis.

Out of the 40 students surveyed, 10 do not belong to a major political party, so the proportion is 10/40 = 0.25.

We can then multiply this proportion by the total number of classmates to estimate the number who do not belong to a major political party:

0.25 * 250 classmates = 62.5 classmates

So about 62 or 63 of the 250 classmates are estimated to not belong to a major political party.

Answer:

D. $0.22

Step-by-step explanation:

The pie is shaped like a circle

The area of a circle with radius r = πr²

This circular pie has a diameter of 8 inches

Radius = diameter/2 = 8/2 = 4 inches

Surface area of pie = π 4² = 16 π square inches

Cost of pizza = $11.05

Cost per square inch = Cost/Area = 11.05/16π = $0.22 rounded to nearest cent

I don't know if its right, but here's what I find.

The number of solutions that the system of equations has is given as follows:

The system of linear equations represented in the graph have

No solutions.

The first step in obtaining the number of solutions of the system of equations is obtaining the linear function that represents each line.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

m is the slope.

b is the y-intercept.

here, we have,

The first line goes through these following points:

(0,3) and (3,4).

The slope is given by change in y divided by change in x, hence:

slope = 3

When x = 0, y = 3,

hence the intercept is of b = 3

and the function is given as follows:

y = 3x - 3

The second line goes through these following points:

(0,-2) and (3,-1).

Hence the slope is of:

m = 3

The intercept is of b = -2,

and the equation is given as follows:

y = 3x-2.

Hence the solution is obtained as follows:

3x - 3=3x-2.

i.e.

The system of linear equations represented in the graph have

No solutions.

Answer:

Option B. N=24; 1%-3.6; PV = ; PMT=-415; FV=0; P/Y=12; C/Y=12; PMT:END

Step-by-step explanation:

The TVM (Time Value of Money) Solver on a graphing calculator is used to calculate the present value (PV) of an investment. The input values for the solver include the number of periods (N), the interest rate (I%), the present value (PV), the payment (PMT), the future value (FV), the payment frequency per year (P/Y), and the compounding frequency per year (C/Y). In this case, the expression ($415)((1+0.003)24 - 1) is equivalent to the future value of an investment that receives a payment of $415 every period for 24 periods, with an interest rate of 0.3% per period. By plugging in N=24, I%=3.6, PV=0, PMT=-415, FV=0, P/Y=12, and C/Y=12 into the TVM Solver with PMT as the payment type, the same value for PV will be returned as the expression ($415)((1+0.003)24 - 1).

Answer:

Step-by-step explanation: We can solve it by doing a cross multiplication, basically finding the X, which is how much he'd pay for 10 pounds:

24 ------- 4

x ---------- 10

You can read this as "if 24 dollars is 4 pounds, how many dollars is 10?"

Anyways, so we multiply on a "X" shape, like this:

4x = 24 x 10

The equation will look better if you multiply the X first.

CONTINUING:

4x = 24 x 10

4x = 240

x = 240/4

x = 60

Therefore, Jackson would pay 60 dollars for 10 pounds of apples.

We could also do this by finding out first how many pounds of apples you can get with 1 dollar, we would do the same thing as before, but now looking for the pounds, not the dollars:

24 ------- 4

1 --------- X

24x = 4

x= 4/24

x= 0,166

So you can buy 0,16 pounds of apples with 1 dollar, so if we want to find out how much we can buy with 24 dollars we multiply 0,166 by 24, which is 3,984, approximately 4 pounds.

But since working with small numbers is quite odd sometimes, I recommend you do this equation with the first method I mentioned.

Bobby around 131 minutes and Billy around 111 minutes

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

To solve the problem it is important to raise equations regarding what happens.

They tell us that Billy (Bi) and Bobby (Bo) can mow the lawn in 60 minutes. That is to say that what they prune in a minute is giving as follows:

1 / Bo + 1 / Bi = 1/60 (1)

They say Billy could mow the lawn only in 20 minutes less than it would take Bobby, therefore

1 / Bi = 1 / (Bo-20) (2)

Replacing (2) in (1) we have:

1 / Bo + 1 / (Bo-20) = 1/60

Resolving

(Bo - 20 + B0) / (Bo * (Bo-20) = 1/60

120 * Bo - 1200 = Bo ^ 2 - 20Bo

Rearranging:

Bo ^ 2 - 140Bo -1200 = 0

Now applying the general equation

Bo = 130.82 or Bo = 9.17, this last value cannot be because Billy took 20 minutes less and neither can he prune faster than the two together, therefore Bobby only takes around 131 minutes and Billy around 111 minutes

Checking with equation 1:

1/131 +1/111 = 1/60

Answer:

The solutions are given below:-

Part (a),

X₁ + X₂ have distribution Bi(n₁+n₂, p)

Part (b),

P(X ₁+ X₂ = 1 | X₂ = 0) =  np(1-p)ⁿ¹⁻¹

P(X₁+X₂ = 1| X₂ = 1) = (1-p)ⁿ¹

P(X₁ + X₂ = 1) = (1-p)ⁿ¹ * np(1-p)ⁿ²⁻¹+ (1-p)ⁿ²*np(1-p)ⁿ¹-¹

Since both variables are independent but they have the same probability parameter, you can interpret that as if the experiment that models each try in both variables is the same.

When you sum both random variables together, what you obtain as a result is the total amount of success in n₁+n₂ tries of the same experiment, thus X₁+X₂have distribution Bi(n₁ + n₂, p).

b)

Note that, if X₂ = k, then X₁ +X₂ = 1 is equivalent to X₁ = 1-k. Since X1 and X₂ are independent, then P(X₁ +X₂ = 1| X₂ = K) = P(X1=1-k|X₂=k) = P(X₁ = 1-k).

If k = 0, then this probability is equal to P(X₁ = 1) = np(1-p)ⁿ¹⁻¹

If k = 1, then it is equal to P(X₁ = 0) = (1-p)ⁿ¹

Thus,

P(X₁+X₂ = 1) = P(X₁+X₂ = 1| X₂ = 1) * P(X₂=1) + P(X₁+X₂ = 1| X₂ = 0) * P(X₂ = 0) = (1-p)ⁿ¹ * np(1-p)ⁿ²⁻¹+ (1-p)ⁿ²*np(1-p)ⁿ¹-¹.

Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.

NUMBER 25

x = 53° (alternate angles)

x + y + 49° = 180° (sum of angles in a triangle is 180°)

53 + y + 49 = 180

y + 102 = 180

y = 180 - 102

y = 78°

NUMBER 26

y = 125° (corresponding angles)

x + y = 180° (sum of angles on a straight line is 180° )

x + 125 = 180

x = 180 -125

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

List Price = $5800

Trade  discount = 50%

So, Price after discount
