Hence, in answering the stated question, we may say that As a result, cylinder Kendra has approximately 1.45 pounds more freeze pop than Luke.

The cylinder, which is frequently a three-dimensional solid, is one of the most basic curved geometric forms. In elementary geometry, it is called a prism with a circle as its basis. A cylinder is also defined as an infinitely curved surface in several modern domains of geometry and topology. A "cylinder" is a three-dimensional object with curved sides and round tops and bottoms. A cylinder is a three-dimensional solid figure with two identical circle bases linked by a curving surface at the cylinder's height, which is determined by the distance between the bases from the centre. Cold beverage cans and toilet paper wicks are both examples of cylinders.

1.5 cubic inches = 1/3 * 2.25 * 2

1.5 * 0.8 = 1.2 lbs.

* radius2 * height = * 12 * 4 = 4 cubic in.

Kendra's freeze pop has the following mass:

4 * 0.2 = 0.8 lbs.

The volume for Luke's freeze pop is:

*1.52 x 3 = 6.75 cubic inches

And the majority is:

6.75 * 0.05 = 0.3375 lbs

1.2 pound Benjamin

Kendra weighs 0.8 2.51 pounds.

Luke: 0.3375 1.06 lbs.

As a result, Kendra is consuming the most freeze pop, weighing around 2.51 pounds.

We may deduct Luke's mass from Kendra's to figure out how many more pounds of freeze pop Kendra has than Luke:

2.51 - 1.06 1.45 lbs.

As a result, Kendra has approximately 1.45 pounds more freeze pop than Luke.

Answer:

Therefore, when the value of d is decreased by 2, the value of g changes by -3. In other words, g decreases by 3.

Step-by-step explanation:

We can start by solving the given equation for g:

4g = 8d + 20

g = (8d + 20) / 4

g = 2d + 5

So, we know that g is a function of d and is equal to 2d + 5.

Now, if we decrease the value of d by 2, we get:

d' = d - 2

Substituting this value of d' in the equation for g, we get:

g' = 2d' + 5

g' = 2(d - 2) + 5

g' = 2d - 4 + 5

g' = 2d + 1

Therefore, when the value of d is decreased by 2, the value of g changes by -3. In other words, g decreases by 3.

The probability of getting a score less than 4.3 for standard postage is 0.77

In this scenario, f(x) = (3/125) x^2 is a probability density function for the weight of a letter, x, for standard postage where x ∈ (0,5). Thus, the integral of the probability density function between two bounds would give the probability of the event occurring. The probability of getting a score less than 4.3 can be calculated as follows:Pr(X < 4.3) = ∫_0^4.3(3/125) x^2 dx= [(3/125) * (1/3) * 4.3^3] - [(3/125) * (1/3) * 0^3]= 0.77

What is an exponential function?

A mathematical function called an exponential function is employed frequently in everyday life. It is mostly used to compute investments, model populations, determine exponential decline or exponential growth, and so forth. When the input variable x appears as an exponent in the formula f(x) = aˣ, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x. A constant serves as the exponent in an exponential function, but not the other way around (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

The complete question is given below.

The initial value of the medication = 400 mg

This is the value of a.

a = 400

b is the growth or decay factor in the exponential function formula.

In this question, it is the decay factor.

b = 1-r

where r is the decay rate = 1/3

b = 1-1/3 = 2/3

The exponential function is given by the formula:

If 1% of the phones were broken, then the number of good phones is 99% of 4,028:

99/100 x 4,028 = 3,987.72 (rounded to 3,988)

Out of the 3,988 good phones, 50% were sold to another city:

50/100 x 3,988 = 1,994

So, the remaining number of good phones that were sold locally is:

3,988 - 1,994 = 1,994

To find the percentage of phones sold locally, we need to divide the number of phones sold locally by the total number of phones:

1,994 / 4,028 = 0.494

Then, we can convert this decimal to a percentage and round to the nearest one percent:

0.494 x 100 ≈ 49%

Therefore, approximately 49% of the phones were sold locally.

The fewest number of cards you will have to look at the back of to know what color the back of each card is 2

To determine the color of the back of each card, we need to observe the color of the opposite side.

We can start by looking at the two-sided white card.

Since both sides of the card are white, no matter which side we look at, we can't determine the color of the back of the card.

So, we have to move on to the other cards.

Next, we can look at the two-sided black card. If we look at either side of this card, we know that the back of the card must also be black.

So, we have determined the color of the back of this card by looking at just one side.

The above means that, in the worst-case scenario, we will have to look at three cards, but we only need to look at two sides of each card

The amount of pizza should be:

The maximum daily profit is $1,200

Let:

x be the number of small pizzas produced

y be the number of large pizzas produced

The problem can be formulated as follows:

Objective function:

To maximize the profit. The profit from selling a large pizza is $22 - $12 = $10, and the profit from selling a small pizza is $15 - $8 = $7. So the total profit can be expressed as:

Profit = 10x + 7y

Constraints:

x ≤ 40 (limited freezer space for small pizzas)

y ≤ 60 (limited freezer space for large pizzas)

x + y ≥ 70 (enough workers to prepare at least 70 pizzas)

8x + 12y ≤ 800 (cost constraint)

Solving the problem using linear programming:

Corner point (0, 70): Profit = 10(0) + 7(70) = $490

Corner point (20, 50): Profit = 10(20) + 7(50) = $1,200

Corner point (60, 10): Profit = 10(60) + 7(10) = $610

x = 20

y = 50

maximum daily profit = $1,200

We see that the data is not normally distributed, but rather skewed to the right. Therefore, the mean will be greater than the median, as the mean is affected by outliers and extreme values, which in this case will pull it towards the higher end.

Furthermore, since there is no single value that appears more frequently than any other, there is no mode for this data set.

Therefore, the statement that must be true is:

The answer to your question is:

The correct answer is b) "Please talk a little louder."

Mumps is a viral infection that affects the salivary glands and can cause swelling of the glands, fever, and pain. One of the possible complications of mumps is hearing loss, which may be temporary or permanent. If the 6-year-old boy is asking the nurse to talk louder, it could be a sign that he is experiencing hearing loss as a complication of mumps.

Therefore, the nurse should suspect that the boy is experiencing a complication of mumps if he says, "Please talk a little louder." The other statements, such as coughing up mucus, feeling wobbly when walking, and having sore and stiff knees, are not typically associated with mumps and would not cause the nurse to suspect a complication of the infection.

In conclusion, the statement that would cause the nurse to suspect the 6-year-old boy is experiencing a complication of mumps is "Please talk a little louder."

The estimated probability of the spinner landing on blue is 0. This means the spinner will not land on blue.

Probability is the measure of how likely an event is to occur out of the number of possible outcomes. It is expressed in terms of a number between 0 and 1, where 0 means that the event is impossible and 1 means the event is certain. Probability is used to calculate the likelihood of an event or outcome in a variety of situations, from predicting the weather to playing the lottery.

The estimated probability of the spinner landing on blue can be calculated by using the ratio of the frequency of red to the frequency of green.

As the ratio is 4 : 7, the frequency of red is 4/11 of the total frequency of 100 spins. The frequency of green is 7/11 of the total frequency of 100. Therefore, the frequency of blue is 100-(4/11+7/11) which is 1 – (11/11) = 0.

Therefore, the estimated probability of the spinner landing on blue is 0. This means the spinner will not land on blue.

To calculate the estimated probability, first we need to calculate the total frequency of all the sections. This is done by adding all the frequencies of the sections together. In this case, the total frequency is 100. Then using the ratio of the frequency of red to the frequency of green, calculate the frequency of red and the frequency of green. Subtract the total frequency and the total frequency of red and green from the total frequency, to get the frequency of blue. Finally, divide the frequency of blue by the total frequency and convert it into a decimal. This will give us the estimated probability of the spinner landing on blue.
