Answer:

0.4185;

0.8835;

$14500;

No

Step-by-step explanation:

Given that :

a = 10200

b = 14500

f(y) = 1 /(b - a) = 1/(14500 - 10200) = 1/4300 = 0.0002325

A.)

P(x <12000) = ∫fydy at(12000 ; 10200) = ∫0.0002325dy at(12000 ; 10200)

P(x < 12000) = 0.0002325(12000) - 0.0002325(10200) = 0.4185

B.)

P(x <14000) = ∫fydy at(14000 ; 10200) = ∫0.0002325dy at(14000 ; 10200)

P(x < 14000) = 0.0002325(14000) - 0.0002325(10200) = 0.8835

(c.) 14500 ; because competitor's bid is at most 14500

D.) No ; Because by bidding $14500 ; getting the property is certain ; once the property is gotten, then it could be resold for $16000, to make a profit of $1500 ; by bidding less, winning the bid becomes uncertain which may means the profit might be lost in the long run.

Answer:

Sarah ate 2, atil ate 2

Step-by-step explanation:

The total number of cookie Sara got = y

Atill got 2 more than Sara so his total cookies is = 2+y

Sarah ate half if hers = y/2

Atil ate 1/3 of his = 2+y/3

We have

Y/2 = 2+y/3

Then we cross multiply

3y = 2(2+y)

3y = 4 + 2y

3y - 2y = 4

Y = 4

Since y = 4,

Sara ate 4/2 cookies = 2

Then atil ate 2+4/3 = 6/3 = 2 cookies

Answer:

$1

Step-by-step explanation:

If 5 pens = $p, then 1 pen = $p/5.

But because 5 pens = $p, it would be the same thing as 5 = p because you just take off the labels.

So p = 5 and one pen would be:

$p/5 = 1

5/5 = 1

1 = 1

Answer:-1

Step-by-step explanation:f(x)=3-x2

This is also...

f(x)=3+[(-1)(x2)]

We will execute the exponential. Then, we will multiply the result by the coefficient of -1.

f(-2)=3-(-2)2

f(-2)=3-(+4)

f(-2)=3-4

f(-2)=-1

Answer:

y=2x+3

Step-by-step explanation:

the equation of the line given in y=mx+b form is for m being the slope and b being the y intercept

we are given a point (1,5) and a slope (2)

since we know the slope, we can plug thatk known value into the equation:

y=2x+b

now we need to find b

because the line will pass through the point of (1,5), we can use it to solve for b

substitute 5 as y and 1 as x

5=2(1)+b

5=2+b

3=b

therefore the equation is

y=2x+3

Answer:

Physical is the answer

When using the measures of centers, the first step you do with the data is to find the average value of the dataset. This is done by calculating the mean or arithmetic average of the data.

The mean is obtained by adding up all the values in the dataset and then dividing by the total number of values present in the dataset.

The formula for the mean is: Mean = Sum of all values in the dataset / Total number of values in the dataset.

The mean is a good indicator of the central tendency of the data, as it is sensitive to all the values present in the dataset.

However, it can be affected by outliers, which are values that are significantly different from the other values in the dataset.

In such cases, the median, which is the middle value when all the values in the dataset are arranged in ascending or descending order, can be a more appropriate measure of center.

Answer:

The width is 9

Step-by-step explanation

Area formula is Length time width

9x7=63

If they are doubled, 18x14=252

Answer:

9 is the width of the cornfield. the area if both L and W doubled would be 252

Step-by-step explanation:

all you gotta do is divide 63 by 7 and you will get the width, 9.

formula: A/L=W

-------------------------------------------------------------------------------------------------------------

the area would be 252 if doubled both length and width because its multiplying 2 by 7 and 9, equaling to 14 and 18, which you multiply that together.

Answer:

exterior angle = the sum of two remote interior angles

14x + 1 = 89 + 5x - 7

=> 9x = 81

=> x = 9

substitute x = 9 into angle H (5x - 7)

=> 5(9) - 7 = 45 - 7 = 38

Answer:

Its D. 3cm

____________

Answer:

D=3

Step-by-step explanation:

Split this figure into 2 parts. Now you have 2 rectangles. One with sides 6 and 12. Other with sides (10 - 6) =4, and a.

Area of one rectangle is 12 × 6 = 72

Area of 2nd rectangle is 4 × a = 4a.

Since we know the total area of figure is 84

that means

72 + 4a = 84

4a = 84 - 72

4a = 12

a = 12 ÷ 4 = 3

a=3

Answer:

After 5 years of investment, Suzanne will have $ 4,400 in her account, while Derek will have $ 4,416.32 in his account.

Step-by-step explanation:

Since Suzanne deposits $ 4000 in an account that earns simple interest at an annual rate of 2%, and Derek deposits $ 4000 in an account that earns compound interest at an annual rate of 2% and is compounded annually., Both for a period of 5 years, to determine how much money each one will have in their account after 5 years, the following calculation must be made:

Suzanne:

((4,000 x 0.02) x 5) + 4,000 = X

(80 x 5) + 4,000 = X

400 + 4,000 = X

4,400 = X

Derek:

4,000 x (1 + 0.02 / 1) ^ 5x1 = X

4,000 x 1.02 ^ 5 = X

4,416.32 = X

Thus, after 5 years of investment, Suzanne will have $ 4,400 in her account, while Derek will have $ 4,416.32 in her account.
