Which expression is equivalent to the expression (1 + 4x) + 2x

Answer:

P=2.66m

A=.3318m

A=.79 * .84

Answer: 10

Step-by-step explanation:

Opposite sides of a parallelogram are congruent, so [tex]17=y+7 \longrightarrow y=10[/tex]

Answer:

b = - a

Step-by-step explanation:

given b varies directly with a then the equation relating them is

b = ka ← k is the constant of variation

to find k use the condition b = 2 when a = - 2 , then

2 = - 2k ( divide both sides by - 2 )

- 1 = k

then

b = - a ← equation of variation

Reason:

Complementary events have their probabilities add to 1.

P(A)+P(B) = 1

P(B) = 1 - P(A)

For example,

P(A) = the chance it rains = 30% = 0.30

P(B) = the chance it doesn't rain

P(B) = 1 - P(A) = 1 - 0.30 = 0.70 = 70%

The equation that relates the probability of A and B is P(B) = 1 - P(A).

A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1.

As per the given data:

We are given two events, event A and event B.

We are also given the relationship between the two events.

It's given that A and B are complements of each other.

Let's assume that the probability of the event B is P(B).

The sample space for this situation when only 2 events are there will be

(A, B)

We are given that A and B are complements of each other.

This means that the complement of A is equal to the probability of event B.

P(A') = 1 - P(A)

P(B) = P(A')

∴ P(B) = 1 - P(A)

The equation that relates the probability of A and B is P(B) = 1 - P(A).

Hence, The equation that relates the probability of A and B is P(B) = 1 - P(A).

#SPJ2

Answer: A origin

Step-by-step explanation:

Answer:

1 gal =231 cu/in

r^2pi*ht=area

36pi*7=    791.68cu/in

231*3.25=750cu/in

              41.68/(r^2pi)

            =41.65/113.1=.368"

Step-by-step explanation:

Note that 1 gallon = 231 cubic inches.

Volume of liquid = 231 cubic inches = PI*R^2*H  (equation for volume of a cylinder)

We have a radius (half diameter), so we can figure out the height of the liquid.  

To figure how far below the top the liquid is, we subtract the height of the liquid from the height of the punch bowl (7 inches).

Answer

[tex]x=\frac{11}{3}[/tex]

Explanation

Based on the given conditions, formulate:: [tex]y=3[/tex]

Substitute [tex]y=3[/tex] into [tex]y=-6x+25[/tex] :: [tex]3=-6x+25[/tex]

Rearrange variables to the left side of the equation: [tex]6x=25-3[/tex]

Calculate the sum or difference: [tex]6x=22[/tex]

Divide both sides of the equation by the coefficient of variable: [tex]x=\frac{22}{6}[/tex]

Cross out the common factor: [tex]x=\frac{11}{3}[/tex]

Answer:

2/935

Step-by-step explanation:

I have attached an image of the equation to use. Assuming that this is without replacement, we'll be taking out one piece out of the bag every time that one is chosen.

Therefore, for probability, the fraction is part/whole. We first have 9 red to 36 pieces in total, but if we take one out, we'll get 8 red left in the bag, and 35 pieces in total. This continues until we fulfill the prophecy (I don't know. qualifications?) that 4 of the pieces are red.

You can try this for yourself, but once simplified, it should be 3024/1413720, which simplifies to 2/935.

Please let me know if you need more clarification or have issues! probability can be confusing :)

\large \sf \underline{Answer:}[/tex]

A. Linear

====================================

[tex]\large \sf \underline{Explanation:}[/tex]

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

====================================

Answer:

Step-by-step explanation:

use the point slope formula  

y - y1 = m(x -x1)

where "m" is an undefined slope

and plug in the given point   (4,7)  it's form is  (x1,y1)

y-7 = m(x - 4)

y = m(x - 4 )  + 7

Area

Answer:

Discount  = $4.50
Discounted Price = $40.50

Step-by-step explanation:

First you need to find what 10% of $45 is. To do that you need to divide $45 by 10 or just move the decimal point one space to the left. The answer would be $4.50. Then, you need to subtract $4.50 from $45 as we are calculating the discounted price. The answer would be $40.50.

Equation:
$45 ÷ 10 = $4.50 (discount)
$45 - $4.50 = $40.50 (discounted price)

Answer: 17.4

Step-by-step explanation: Area of a Square

Area of a rectangle = s².

s is the side length.

Area of Circle

4 quarter circles equals a full circle.

Area of a full circle = πr².

There are four quarter circles in the diagram given, therefore:

Area of the shaded region = area of square - area of full circle

= 9² - π(4.5²)

= 17.38.

Therefore, the area of the shaded region, to the nearest tenth, is about: 17.4 m².

Answer:

P = 20

Step-by-step explanation:

Mean

The good has an income elasticity of demand of -2. 0. This means that the good is inferior goods.

An inferior good occurs when an increase in income causes a fall in demand.

An inferior good has a negative income elasticity of demand. (YED) Inferior goods are characterized by low quality – and are goods with better alternatives.

Suppose that good has an income elasticity of demand of -2. 0. This means that the good is inferior goods.

An inferior good is one whose demand drops when people's incomes rise. When incomes are low or the economy contracts, inferior goods become a more affordable substitute for more expensive goods.

Inferior goods are the opposite of normal goods, whose demand increases even when incomes increase.

Hence, the good has an income elasticity of demand of -2. 0. This means that the good is inferior goods.

The statement first, statement third, and the statement fifth are correct because the mean absolute deviation are the same.

It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.

We have data:

Yard Works: 7, 9, 7, 12, 5

Grow Station: 9, 11, 6, 12, 7

The mean for yard works = 40/5 = 8

The mean for grow station = 45/5 = 9

The mean absolute deviation for yard work = 2

The mean absolute deviation for grow station = 2

Answer: A, C, E.

Step-by-step explanation: I got it right on the test

Step-by-step explanation: the answer for this question should be 81.64 because to find the circumference you need to know the circumference formulas which is  C=TT times d or          C= 2 times TT times r.

C= 3.14 times 26          C= 2 times 3.14 times 13

                                       C= 81.64

C= 81.64

so the answer is 81.64 for the circle's circumference so hopefully that is the correct answer and have a great day
