The figures below are rectangles. What polynomial in standard form represents the area of the shaded region?

The approximate value of the median is 25

The median is the middle number in a sorted, ascending, or descending, list of numbers and can be more descriptive of that data set than the average.

The median is sometimes used as opposed to the mean when there are outliers in the sequence that might skew the average of the values.

To find the median, calculate the value mean by adding together the middle values and dividing them by two.

Hence, the approximate value of the median is Median

The checkbook balance is $5703.25.

To find the checkbook balance, we need to start with the original balance and then subtract the amounts of the checks written and add the amount of the deposit.

Original balance: $7349.44

Checks written: $1349.67 + $344.12 = $1693.79

Deposit: $956.60

To find the checkbook balance, we can subtract the total amount of the checks written from the original balance and then add the deposit:

Checkbook balance = Original balance - Checks written + Deposit

Checkbook balance = $7349.44 - $1693.79 + $956.60

Checkbook balance = $5703.25

Therefore, the checkbook balance after store manager deposited $956.60 is $5703.25.

In total, Christian had 62 customers in the last week.

With a radius of 20 feet and 10 rounds traversed, the total distance equates to approximately 1256.6 feet.

When calculating the circumference (C) of a circle, the formula 2 * π * radius (R) is employed.

Taking into consideration R = 20 feet, we shall arrive at the following figure:

C = 2 * π * 20

C ≈ 2 * 3.14159265359 * 20

C ≈ 125.66 feet

If we use this calculation to determine the total distance covered after running 10 laps around a track, our equation morphs into Circumference (C) multiplied by the Number of laps (L).

When L equals 10, it follows that:

Total distance ≈ 125.66 feet * 10

Total distance ≈ 1256.6 feet

Therefore, with a radius of 20 feet and 10 rounds traversed, the total distance equates to approximately 1256.6 feet.

The value of the side length h is 19.1 cm.

The figure in the image is a right triangle:

Angle θ = 47 degrees

Opposite to angle θ = 14cm

Hypotenuse = h

To solve for side length h, we use trigonometric ratio.

Note that: sine = opposite / hypotenuse

Plug in the values and solve for h.

sin( 47° ) = 14 / h

h = 14 / sin( 47° )

h = 19.1 cm

Therefore, the value of h is 19.1 cm.

Answer:

To find the probability that a person surveyed is under 40 given that he or she gets the news by reading the paper, we need to use Bayes' theorem:

P(Under 40 | Read paper) = P(Read paper | Under 40) * P(Under 40) / P(Read paper)

where

P(Under 40 | Read paper) is the probability that a person is under 40 given that he or she gets the news by reading the paper

P(Read paper | Under 40) is the probability that a person under 40 reads the paper (36/80)

P(Under 40) is the overall probability of selecting a person under 40 (40/80)

P(Read paper) is the overall probability of selecting a person who reads the paper, calculated as the sum of those who are under 40 and read the paper and those who are 40 or older and read the paper (36+24)/(80)

Plugging in the values, we get:

P(Under 40 | Read paper) = (36/80) * (40/80) / ((36+24)/80)

P(Under 40 | Read paper) = 0.6

So the probability that a person surveyed is under 40, given that he or she gets the news by reading the paper, is 60%.

The requried probability that Luc gets both questions correct is 1/16 or approximately 0.0625.

The probability of guessing a single question correctly is 1/4, since there are 4 answer choices and only 1 is correct. Since the questions are independent, the probability of guessing both questions correctly is the product of the probability of guessing each question correctly.

Therefore, the probability that Luc gets both questions correct is:

P(both correct) = P(first correct) * P(second correct)

P(both correct) = (1/4) * (1/4)

P(both correct) = 1/16

Thus, the probability that Luc gets both questions correct is 1/16 or approximately 0.0625.

Step-by-step explanation:

If we look at the number we see .320, as we can see the number in the front is 3 and behind that is 2, when we are rounding the key thing to always remember is if its greater than 5 we round up if not go down so sense 3 doesn't go over 5 we don't change the number in front of it 0 and the same thing with 2 but we wouldn't change the 3 instead. so sense .320 doesn't qualify as a whole number we do not need it so we get the answer,

The rate of car is 35 mph.

Given that engineer traveled 140 mi by car and then an additional 750 mi by plane. The rate of the plane was three times the rate of the car.

Let c be the rate of wind.

215 + c = rate of plane with wind

215 - c = rate of plane against wind

Therefore, the travel time =distance/rate

⇒ 750/(215+c) = 540/(215-c)

Cross multiplying we get,

540(215+c) = 750(215-c)

116100+540c = 161250-750c

1290c = 45150

The magnitude of the vector 4v is 4 times the magnitude of v, which is equal to 4 √29.

Given the vector v = 5i - 2j, we can find the magnitude or norm of the vector ||v|| using the formula:

||v|| = √(v · v)

where · denotes the dot product of the vector with itself.

Substituting the values of the vector v, we have:

||v|| = √((5i - 2j) · (5i - 2j))

Expanding the dot product using the distributive law, we get:

||v|| = √(25i² - 20ij + 4j²)

Since i² = j² = 1 and ij = ji = 0, we can simplify this expression to:

||v|| = √(25 + 4) = √29

Thus, the magnitude of the vector v is √29.

Now, we need to find the magnitude of the vector 4v. Using the property that ||kv|| = |k| ||v|| for any scalar k and vector v, we have:

||4v|| = |4| ||v|| = 4 √29

In summary, the magnitude of the vector v is √29, and the magnitude of the vector 4v is 4 √29.

The simplified expression is 120x³ + 120x².

To simplify the expression 5x(2x+2)12x, we can use the distributive property of multiplication over addition and simplify the resulting terms.

First, we distribute 5x to the expression (2x+2), which gives us:

5x(2x+2) = 10x² + 10x

Next, we can multiply the result by 12x:

12x(10x² + 10x) = 120x³ + 120x²

Therefore, the simplified expression is 120x³ + 120x².

We can see that the original expression was a multiplication of three factors, and we used the distributive property to simplify it by expanding and multiplying the resulting terms. The final expression has a common factor of 120x², which we can factor out to get 120x²(x+1).

Step-by-step explanation:

Savings Account B will have more money after 9 years because it is modeled by the exponential equation, and the investment grows exponentially with time

We have,

To determine which savings account has more money after 9 years, we can evaluate the amount of money in each account using the given equations.

For Savings Account A, the equation is:

A = 21.09t + 1125

Substituting t = 9 (since we're interested in the amount after 9 years), we get:

A = 21.09(9) + 1125 = 1300.81

So, after 9 years, Savings Account A will have $1300.81.

For Savings Account B, the equation is:

A = 1125(1 + 0.01875/2)^(2t)

Substituting t = 9, we get:

A = 1125(1 + 0.01875/2)^(2(9)) = 1318.98

So, after 9 years, Savings Account B will have $1318.98.
