Answer: Therefore, the area that is only planted in corn can be expressed as the polynomial y^2 + 14y.

Step-by-step explanation:

The area of the square piece of land is given by the product of its length and width:

Area of square piece of land = (y + 7) * (y + 7)

The area of the small square that was planted with radish is 7 ft. by 7 ft. Therefore, its area is:

Area of small square = 7 * 7 = 49

The area that is only planted in corn is the difference between the area of the square piece of land and the area of the small square that was planted with radish:

Area planted in corn = (y + 7) * (y + 7) - 49

Expanding the expression on the right side, we get:

Area planted in corn = y^2 + 14y + 49 - 49

Simplifying further, we get:

Area planted in corn = y^2 + 14y

Assuming the triangles in the pair above are similar, the value of x is equal to 11.

In Mathematics, the basic proportionality theorem states that when any of the two (2) sides of a triangle is intersected by a straight line which is parallel to the third (3rd) side of the triangle, then, the two (2) sides that are intersected would be divided proportionally and in the same ratio.

By applying the basic proportionality theorem to the given triangle, we have the following:

UV/VW = SU/ST

(5x + 11)/88 = 18/24

By cross-multiplying, we have the following:

By rearranging and collecting like-terms, the value of x is given by:

120x = 1,584 - 264

120x = 1,320

x = 1,320/120

The new mean cost of a box of Cheerios Out Crunch is $4.40. This means that, on average, customers can expect to pay $0.40 more for a box of cereal after the price increase.

The new mean cost of a box of Cheerios Out Crunch after a 10% increase in price would be $4.40.

To see why, we can start with the original mean cost of $4.00 per box. To calculate a 10% increase, we can multiply the original mean cost by 1.10 (or 110% as a decimal), which gives:

$4.00 x 1.10 = $4.40

The mean cost is the proportion of the cost of the multitude of items to the absolute number of items. In Maths, we likewise have the term called "normal". The normal of some random arrangement of information is known as the mean of information.

Answer:

Step-by-step explanation:

The length of time it would take you to pay off the balance at $ 50 per month is 29.5 months.

The monthly payment on the credit card if one was to pay off the debt in 2 years is $132.34.

To find out how long it will take to pay off the credit card balance, we can use the TVM (Time Value of Money) solver.

First, we need to convert the APR to a monthly interest rate:

i = (1 + 0.19)^(1/12) - 1 ≈ 0.0149 or 1.49% (monthly interest rate)

Now, we can use the TVM formula to find the number of periods (n):

PV = PMT x (1 - (1 + i)^(-n)) / i

1,245 = 50 x (1 - (1 + 0.0149)^(-n)) / 0.0149

Solving for n:

n = 29.5 months

To find the monthly payment on the credit card, we are given:

PV (Present Value) = $2,456.80

n (number of periods) = 2 years x 12 months/year = 24 months

APR (Annual Percentage Rate) = 23.99%

We can use the TVM formula to find the monthly payment (PMT):

PV = PMT x (1 - (1 + i)^(-n)) / i

2,456.80 = PMT x (1 - (1 + 0.0182)^(-24)) / 0.0182

Solving for PMT:

PMT = $132.34

Out of the given options, the correct statement concerning the median is option B: In a right-skewed distribution, we expect that the median will exceed the mean.

What is the median?

Median is defined as the middle value in a given set of data. It can also be referred to as the central point of the distribution when the data is arranged in ascending or descending order. In other words, the median divides the data into two equal parts

.Median can be determined as follows:

Arrange the data in ascending or descending order .The median is the middle value of the data set.If there are two middle values, find the average of these two values .The mean is the average of the set of data. It is calculated by adding up all the values and dividing by the total number of values in the set of data. Hence, it gives an idea about the central tendency of the data set. According to the statement concerning the median, we expect that the median will exceed the mean in a right-skewed distribution. This means that the right tail is longer or more spread out than the left tail. The skewness of a distribution is a measure of its symmetry. A distribution can be classified as left-skewed, right-skewed or symmetrical depending on the shape of its histogram. Thus, option B is the correct statement concerning the median.

Step-by-step explanation:

You want to know the total completion time for a project with four activities that take 4, 3, 6, and 7 days.

The project completion time will be determined by the dependencies between activities.

If each activity must be completed before the next, then the total time will be 4+3+6+7 = 20 days.

If there are no dependencies and all activities can be done in parallel, then the total completion time is 7 days, the time required for the longest activity.

√49 is less than 7.1212. In other words, 49−−√ is less than 7.1212.

what is a decimal number?

A decimal number is a real number that is expressed in the decimal system, which is a system of numeration using the base 10. In this system, each digit can take on one of ten possible values, 0 through 9, and the value of each digit is determined by its position relative to the decimal point.

To compare the numbers √49 and 7.1212, we need to find their numerical values.

√49 = 7, since 7 multiplied by itself gives 49.

7.1212 is already a decimal number, so no calculation is required.

To approximate 7.1212, we can look at the digits after the decimal point:7.1212

0.1212

--------

7.0000 + 0.1212

--------

7.1212

Now we can see that 7 is less than 7.1212. Therefore, √49 is less than 7.1212. In other words, 49−−√ is less than 7.1212.

So, the comparison between the two numbers is:

√49 < 7.1212 or 49−−√ < 7.1212.

The time taken for the tub to empty is approximately 9.18 minutes.

Suppose the drain is opened on a tub containing 34 gallons of water.

Water drains out of the bathtub at a rate of 4 gallons per minute.

However, the tap wasn't closed properly, so water is still flowing into the tub at a rate of 0.3 gallons per minute. How many minutes will it take for the tub to empty.

Solution:

We are given:

Initial quantity of water = 34 gallons.

Water flowing out of the tub = 4 gallons/minute.

Water flowing in to the tub = 0.3 gallons/minute

We need to find: Time taken for the tub to empty.

Let us assume that the time taken for the tub to empty is t minutes.

Now, the water that is still present in the tub is (34 - 4t + 0.3t) gallons.

Let us set this expression equal to zero to find the time taken for the tub to empty.

34 - 4t + 0.3t = 0

Simplifying, 34 - 3.7t = 0 or 3.7t = 34 or t = 34/3.7t ≈ 9.18.

The maximum price that consumers are willing to pay for the product is represented by the y-intercept of the parabola, which is 1200. This means that when there is no demand for the product (x=0), the price of the product is 1200 dollars.

The given demand function for a product in dollars is p=1200-0.2x-0.0001x², where 'p' represents the price of the product and 'x' represents the quantity demanded by the consumers.

This demand function is a quadratic function that takes the form of a downward-sloping parabola. It has a negative coefficient for the squared term, which means that the parabola opens downwards. This implies that as the quantity demanded increases, the price of the product will decrease, but only up to a certain point.

The maximum price that consumers are willing to pay for the product is represented by the y-intercept of the parabola, which is 1200. This means that when there is no demand for the product (x=0), the price of the product is 1200 dollars.

As the quantity demanded increases, the price of the product decreases at a decreasing rate. This is because the coefficient of the x-term (-0.2) is smaller than the coefficient of the x²-term (-0.0001x²), which means that the effect of quantity on price decreases as the quantity demanded increases.

However, beyond a certain point, the price starts to increase again, indicating a decrease in demand. This is because the quadratic function is concave downwards, and there is a maximum point (vertex) on the parabola. The quantity demanded at this point is given by the formula

x = -b/2a, where a and b are the coefficients of the x² and x terms, respectively.

Overall, the demand function represents the relationship between the price of the product and the quantity demanded by the consumers. By understanding this relationship, producers can make informed decisions about pricing and production levels to maximize their profits.

Number of different page that numbers contain the digit 1 is 20

We can approach this problem by counting the number of pages that do not contain the digit 1 and subtracting that from the total number of pages, which is 200.

Let's count the number of pages that do not contain the digit 1. We can do this by considering each digit in turn. There are 9 choices for the first digit (it cannot be 1), and 10 choices for each of the remaining digits (since 1 is now allowed). So, there are 9 × 10 × 10 = 900 page numbers that do not contain the digit 1.

Therefore, the number of page numbers that do contain the digit 1 is 200 - 900 = -700.

However, this answer does not make sense since we cannot have negative page numbers. Therefore, there must be a mistake in our calculation. The mistake occurs when we consider the case where the first digit is 1. In this case, there are only 2 digits left to choose from (0 and 2-9), not 10. So, the correct number of page numbers that do not contain the digit 1 is 9 × 2 × 10 = 180.

Therefore, the number of page numbers that do contain the digit 1 is 200 - 180 = 20.

The new variance is  0.35.

The variance of a random variable measures how spread out the values are from the mean.

The formula for the variance is Var(X) = E[(X - E[X])²], where E[X] is the expected value (or mean) of X.

If the price of a box of Cheerios Oat Crunch increases by 25 cents, the new mean cost would be $4.25. To find the new variance, we can use the formula Var(aX + b) = a²Var(X), where a is a constant and b is a constant. In this case, a = 1 (because we are not changing the units of measurement) and b = 0.25 (because we are adding 25 cents to the price).

Therefore, the new variance is Var(X + 0.25) = Var(X) = Var(X) x 1² = Var(X) = 0.35.

This means that the variance remains the same even though the price has increased. This is because the variance is a measure of how spread out the values are from the mean, and the mean has shifted by the same amount as the price increase. Therefore, the distance between the values and the new mean is the same as the distance between the values and the old mean, so the spread is unchanged.

The variance is a measure of how spread out a set of data is from its mean. It is calculated as the average of the squared differences between each value and the mean. The formula for variance is Var(X) = E[(X - E(X))²], where E is the expected value or mean of X.

In this case, we are given that the mean cost of a box of Cheerios Oat Crunch is $4.00 and the variance is 0.35. This means that the average squared difference between each box's cost and the mean cost is 0.35.

Now, if the price of each box increases by 25 cents, this means that the new mean cost will be $4.25. However, this does not affect the variance directly. This is because the variance only measures how spread out the data is from the mean, and the mean has shifted by the same amount as the price increase.

To see this more clearly, imagine a set of data that has a mean of 4 and a variance of 0.35. If we add 0.25 to each value, we get a new set of data that has a mean of 4.25. However, the spread of the data is still the same; that is, the distance between each value and the new mean is the same as the distance between each value and the old mean. Therefore, the variance remains the same even though the price has increased.

In summary, the variance measures how spread out a set of data is from its mean, and a shift in the mean does not affect the variance directly.

The critical value that corresponds to a 90% confidence level is 1.645.

When we are given a confidence level, we can use a confidence interval to calculate the margin of error, and with that we can find the critical value. The critical value is the value that represents the number of standard deviations we need to go from the mean to capture a certain proportion of the distribution.

For example, for a 95% confidence level, we want to capture 95% of the distribution, so we need to go 1.96 standard deviations from the mean.To find the critical value that corresponds to a given confidence level, we need to use a table of critical values for the standard normal distribution. This table tells us how many standard deviations we need to go from the mean to capture a certain proportion of the distribution.

For example, the critical value for a 95% confidence level is 1.96, while the critical value for a 99% confidence level is 2.58. So, if we are given a confidence level of 90%, we need to find the critical value that corresponds to capturing 90% of the distribution.Using the table of critical values, we find that the critical value for a 90% confidence level is 1.645.
