Use the Distributive Property to simplify 6x²[(3x - 4) + (4x + 2)]

Answer:

-24a+20

Step-by-step explanation:

just use distrubitive property

A squared-- so the length of one of the shorter sides squared-- plus the length of the other shorter side squared is going to be equal to the length of the hypotenuse squared.

where a and b are legs and c is the hypotenuse

we are given one leg (OP=8) and the hypotenuse (ON=18) so now we can plug in these numbers to find PN

8²+b²=18²

64+b²=324

b²=260

b=√260

b=√4 * √65

b=2√65

now that we have the value of PN, we can get the value of LN by doubling 2√65

2(2√65) = 4√65

so your answer should be:

LN = 4√65

a) The average cost of the promotion is $ 0.01 per liter

b) the probability that Greer will refund more than $25 for a liter is 0.0107.

a.

Mean lifetime mileage : $33,500

Standard deviation of mileage: $3500

Observed miles: 30,000 miles

100 miles failed $1.00

Hence :

If the scale of drawing is 1 inches : 250 inche and the real horse height is 15 inche, then the height of the horse in drawing is 0.06 inches.

The ratio that describes the relationship between the true figure itself and model is called the scale. It serves as a representation of the real statistics in smaller units on maps. A scale of 1:5, for instance, indicates that 1 on the map is approximately the size of 5 in the actual world.

The scale of drawing the horse = 1 inch :

Therefore in scale

Horse height in drawing equals one inch

The  height of the horse = 250 inche

The original height of the horse = 15 inche

The height in the picture = x inches

To find the height the horse in the picture, we have to use proportion

1 inch : 250 inche = x inches : 15 inche

1 / 250 = x / 15

1 × 15= 250x

250x = 15

x = 15/250

x = 0.06 inches

There are three branch prediction scheme: predict not taken, predict taken, and dynamic prediction. assume that they all have zero penalty when they predict correctly and two cycles when they are wrong.

In computer architecture, a branch predictor is a digital circuit that attempts to guess which direction a branch (e.g. an if-then-else construct) is going finally announced. The purpose of the branch predictor is to improve the flow of the instruction pipeline. Branch predictors play a key role in achieving high performance in many modern pipeline microprocessor architectures.

1. If the branch is taken 5% of the time, the branch prediction scheme is ``predicted-taken'' because the process must start fetching and then executing at the target address.

2. If a branch is taken 95% of the time, the branch outcome is known with certainty, so the branch prediction scheme is "unpredictable".

3. If the branch is taken 70% of the time, then the prediction scheme is "dynamic prediction" and the branch prediction can change dynamically during program execution.

Step-by-step explanation:

cuz im smart

please give brainliest

Answer:

The correct answer is B. looking for work/total work force.

Unemployment rates are typically calculated by dividing the number of people who are looking for work by the total work force. The work force includes all people who are currently employed or actively looking for work, regardless of whether they are currently employed. The number of people who are looking for work is determined by surveying individuals and asking them whether they are currently seeking employment. The unemployment rate is then calculated by dividing the number of people who are looking for work by the total work force, and expressing this as a percentage.

The other answer choices are not accurate ways of calculating unemployment rates. Dividing the total work force by the number of layoffs (A) would not give an accurate measure of unemployment, as it would not account for people who are looking for work but have not been laid off. Dividing the number of people looking for work by the total population (C) would also not be an accurate way of calculating unemployment, as it would not take into account people who are not part of the work force (e.g. children, retirees, etc.). Therefore, the correct method for calculating unemployment rates is to divide the number of people looking for work by the total work force.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The unemployment rate for any area is the number of area residents without a job and looking for work divided by the total number of area residents in the labor force.

The marginal revenue function, locate the demand function is P = 0.02x² -0.025x + 138 when R'(x) = 0.06x² - 0.05x + 138 .

Given that,

We have to find for the marginal revenue function, locate the demand function.

Remember that the income is zero if no things are sold:

R'(x) = 0.06x² - 0.05x + 138

p(x) is what.

We know that,

MR = dTR/dx = 0.06x² - 0.05x + 138

Integrating the marginal revenue function , we get total revenue function,

MR = TR

= (0.06x²⁺¹)/(2+1) - (0.05x¹⁺¹)/(1+1) + 138x

= (0.06x³)/3 - (0.05x²)/2 + 138 x

TR  = 0.02 x³ - 0.025 x² + 138 x

TR = (P)(Q) = (P)(x) =  0.02 x³ - 0.025 x² + 138 x

P = ( 0.02 x³ - 0.025 x² + 138 x)/x

P = 0.02x² -0.025x + 138

Therefore, The marginal revenue function, locate the demand function is P = 0.02x² -0.025x + 138 when R'(x) = 0.06x² - 0.05x + 138 .

The mean of the class is 94.6 and the range of the class is 55.

A dataset's mean is the sum of all values divided by the total number of values. It is the most widely used measure of central tendency and is frequently referred to as the "average."

The range of a set of numbers is the difference between its highest and lowest values. To find it, subtract the lowest value from the highest in the distribution.

The given data is 45,68,77,90,90,95,100,100,86,90,50,55.

The mean of the data will be calculated as,

Mean = (sum of the data) / ( number of the data)

Mean = ( 45 + 68 + 77 + 90 + 90 + 95 + 100 + 100 + 86 + 90 + 50 + 55)/12

Mean = 94.6

The range of the data will be calculated as,

Range = Highest value - The lowest value

Range =  100 - 45

Range = 55

The mode of the data is 90 because it has three repetitions.

The median of the data is the middlemost value of the data when the data is arranged in increasing order,

(45,50,55,68,77,86,90,90,90,95,100,100)

Answer:

18 green eyed dolls and 34 blue eyed dolls

Step-by-step explanation:

Cadence has a total of 52 dolls, either green eyed or blue eyed so lets take the number of green eyed dolls as g and the number of blue eyed dolls as b. So you have

b + g = 52

also we know b is 16 greater than g so

b - 16 = g

transpose 16 & g

b - g = 16

Now we add the equations

b+g = 52

b-g = 16

______

2b = 68

(+g and -g cancel each other out)

so b = 34

If we put 34 into an earlier equation

34 + g = 52

g = 52 - 34

g= 18

37,840 is the fox population predicted to be in the year 2019.

What is a growth rate?

The country, territory, or geographic area's yearly average rate of change in population size over a certain time period. It expresses the proportion, usually multiplied by 100, between the annual growth in population size and the total population for that year.

Here, we have

A growth rate of 9% per year means that at the end of each year, the population is 1.09 times what it was at the start of the year.  

We keep this up for t years, starting with an initial population of 20,700, and get

P(n) = 20,700 (1.09)ⁿ

n = years since 2012, when the population was 20,700

For the year 2019,

n = 2019 - 2012 = 7

P(7) = 20,700 (1.09)⁷ ≅ 37,840

Hence, 37,840 is the fox population predicted to be in the year 2019.
