Jogging is one of the few sports that has been consistently increasing over the past few years. the number of people jogging​ (in millions) from the years 2000 to 2009 is given by the equation y equals x plus 26y=x+26​, where x is the number of years after 2000.

Answer: -2

Step-by-step explanation:

Answer:

a).[tex]P_{t}=\frac{5}{3}P_{t-1}[/tex]

b).[tex]A_{t}=300e^{0.1277\times t}[/tex]

c). 6429 bacteria

Step-by-step explanation:

Population of the bacteria grows exponentially.

Therefore, growth of the bacteria will be represented by the formula

[tex]P_{t}=P_{0}e^{kt}[/tex]

Where [tex]P_{t}[/tex] = Population of the bacteria after time t

[tex]P_{0}[/tex] = Initial population of the bacteria

k = growth constant

t = time taken for growth

Now we plug in the values in the formula

[tex]P_{t}[/tex] = 500

[tex]P_{0}[/tex] = 300

Time t = 4 hours

[tex]500=300e^{4k}[/tex]

[tex]e^{4k}=\frac{500}{300}[/tex]

Now we take the natural log (ln) on both the sides

[tex]ln(e^{4k})=ln(\frac{500}{300})[/tex]

4k(lne) = ln(500) - ln(300)

4k = 6.2146 - 5.7038

4k = 0.5108

k = [tex]k=\frac{0.5108}{4}=0.1277[/tex]

a). Recursive formula for the sequence formed by the bacterial growth

Since [tex]P_{t}=(1+r)P_{t-1}[/tex]

500 = (1 + r)300

[tex](1+r)=\frac{5}{3}[/tex]

r = [tex]\frac{5}{3}-1=\frac{2}{3}[/tex]

Therefore, the recursive formula will be

[tex]P_{t}=\frac{5}{3}P_{t-1}[/tex]

b). Explicit formula for the number of the bacteria will be

[tex]A_{t}=300e^{0.1277\times t}[/tex]

c). We have to calculate the number of bacteria after 24 hours

[tex]A_{t}=300e^{0.1277\times 24}[/tex]

[tex]A_{t}=300e^{3.0648}[/tex]

[tex]A_{t}=300\times 21.43[/tex]

[tex]A_{t}=6429[/tex] bacteria

Collagen is a major structural protein in connective tissue, made of fibrous materials predominantly secreted by fibroblasts. It provides strength and flexibility to tissues like tendons, ligaments, and skin. This protein is crucial for maintaining the body's structural integrity.

The smaller number of the two numbers that have a difference of 30 and a ratio of 7:2 is 12.

The difference between the two numbers is 30.

The ratio of the bigger number to the smaller number is 7:2.

The smaller number can be calculated as follows;

let

x = bigger number

y = smaller number

Hence, the difference in the numbers is as follows:

x - y = 30

Also, the ratio of the bigger number to the smaller number is 7:2.

The bigger number can be found using the ratio. Recall x + y is the total sum of the numbers.  

x = 7 / 9(x + y)

x = 7 / 9x + 7 / 9y

x - 7 / 9x = 7 / 9 y

2 / 9 x  = 7 / 9 y

multiply both sides by 9

2x  = 7y

The bigger number is 7 / 2 of the smaller number.

x = 7 / 2 y

Therefore, let's substitute the value of x in equation(i).

Recall x - y = 30

7 / 2 y - y = 30

5 / 2 y = 30

cross multiply

5y = 60

y = 60 / 5

y = 12

Hence,

x = 30 + 12

x = 42

Therefore,

smaller number = 12

Answer:  The correct option is (A) 0.

Step-by-step explanation:  We are given to find the difference between the mean and median of the following data set:

{22, 8, 10 ,18 ,12, 20}.

MEAN:  It is the sum of all the values together divided by the number of values in the set.

So, the MEAN of the given data set is

[tex]m=\dfrac{22+8+10+18+12+20}{6}\\\\\\\Rightarrow m=\dfrac{90}{6}\\\\\Rightarrow m=15.[/tex]

MEDIAN: The median of a data set is given by the middle-most value in the data.

If there is an even number of items in the data set, then the median is found by taking the mean of the two middlemost numbers.

Arranging the given data in ascending order, we have

8, 10, 12, 18, 20, 22.

Since there are 6 values, that is even number of values. so the MEDIAN is given by

[tex]M=\dfrac{12+18}{2}\\\\\Rightarrow M=\dfrac{30}{2}\\\\\Rightarrow M=15.[/tex]

Therefore, m = M.

That is, mean and median of the given data are equal.

Hence, the difference is

m - M = 15 - 15 = 0.

Thus, option (A) is CORRECT.

Answer:

Option A - 0

Step-by-step explanation:

Given : Data set {22, 8, 10 ,18 ,12, 20}

To find : What is the difference between the mean and the median of the data set?

Solution :

Data set in increasing order {8, 10 ,12,18, 20,22}

Mean is defined as the division of sum of set values by total number of values.

[tex]M=\frac{\sum x}{n}[/tex]

Substitute the values we get,

[tex]M=\frac{8+10+12+18+20+22}{6}[/tex]

[tex]M=\frac{90}{6}[/tex]

[tex]M=15[/tex]

So, The mean of the set is 15.

Median of even numbers is the average of two middle terms.

[tex]m=\frac{3rd+4th}{2}[/tex]

[tex]m=\frac{12+18}{2}[/tex]

[tex]m=\frac{30}{2}[/tex]

[tex]m=15[/tex]

So, The median of the set is 15.

Now, The difference of the mean and the median of the set is

[tex]d=M-m[/tex]

[tex]d=15-15[/tex]

[tex]d=0[/tex]

Therefore,Option A is correct.

The difference of the mean and the median of the set is 0.

Answer:

Larry received 1/3 pound of candy from his grandmother and 2/5 pound of candy from his best friend. Larry's sister ate 1/2 pound of candy. How many pounds of candy does Larry have?

the answer is 7/30

Step-by-step explanation:

To solve this problem, we have to make use of the standard probability distribution tables for z test.

Since we are asked to find for the 72 percent level confidence, then this means we are to look for the value of z which gives (100-72)/2 = 14% on both sides of the tail.

So at 14% tail on one side, the z value is approximately:

1.08

Answer:

± 1.08

Answer:

[tex]C(x)=16.99x[/tex]

Step-by-step explanation:

Let x be the number of staplers and C(x) be total cost in dollars of x stapler.

Cost of each stapler = $16.99

So, the formula for total cost is

Total cost = Cost of each units × Number of units

Substitute 16.99 for Cost of each units and x for number of units in the above formula.

Total cost = [tex]16.99\times x[/tex]

Total cost = [tex]16.99x[/tex]

C(x) be total cost in dollars of x stapler. So, the cost function is

[tex]C(x)=16.99x[/tex]

Therefore, the function C(x)=16.99x represents the given situation.

Answer:

Ricardo paid $2.29 too much

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

To begin answering this question we need to calculate the total before applying anything. We calculate this by adding up all the amounts of each item purchased. Like so,

[tex](2*3.49)+(2*2.89)+(3*5.39)+(4*3.49) = Total[/tex]

[tex]6.98+5.78+16.17+13.96 = Total[/tex]

[tex] 42.89= Total[/tex]

Now that we have the total we can apply the 5% discount to this total.

[tex]42.89 * (1-0.05) = 40.75[/tex] ... rounded up

Finally we can apply the 7% sales tax to this purchase to calculate the final price that Ricardo should have paid.

[tex]40.75*(1+0.07) = 43.58[/tex] ... rounded up

As we can see Ricardo paid $2.29 too much

It will take Rafael 10 months to save the down payment.

Method:

To solve this question, round out one of the factors to estimate the product

We have:

340 ≈ 300 (we rounded 340 to the nearest hundred)

Let x represent the number of months, then we have:

300 x X = 3000

3 x 100 x X = 3 x 100 times 10 (for better understanding)

X = [tex]\frac{3000}{300}[/tex]

X = 10

so, it will take him about 10 months to save the down payment.

Notably, we rounded 340 to 300 so that it can be easier to use when calculating.

In the painting 'Three Flags' by Jasper Johns, the size of the largest flag would depend on the canvas or surface used.

In the painting Three Flags by Jasper Johns, he used his encaustic process to create the artwork. Each flag reduced about twenty-five percent in scale as he stacked canvas flags, with the largest one receding into the background. The congealed wax drippings gave the painting a dimensional sculptural appearance.

The stripes and stars on the flags also grow smaller, adding to the illusion of three separate elements. Therefore, in terms of the largest flag Jake can draw, it would depend on the size of the canvas or surface that he is working with.

To calculate 1206 × 5 using expanded form, break 1206 into its place values, multiply each by 5, and then add the results. This gives 6030.
