Explanation:

A permutation is an act of arranging the objects or numbers in order. Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.

The interquartile range of the data will be 13

When arranged from lowest to highest, the IQR reflects the median 50% of values. To calculate the interquartile range (IQR), firstly compute the median (middle value) of the data's lower and upper halves. All those are quartile 1 (Q1) and quartile 3 (Q3) values (Q3). The interquartile range is the difference between quarters three and then one.

first, let us sort the data from lowest to highest

25,25,29,31,33,37,38,42,46

Q1- median of the lower half of the data=(29+25)/2=27

Q3-median of the upper half of the data=(38+42)/2=40

the interquartile range of the data will be Q3-Q1

40-27= 13

Answer: about $100,000.

Step-by-step explanation: i gave an estimate because your answer calls for an estimate, not an exact answer. $100,000 is correct because 24,897*4 = 99,588.

The runner is approximately 7.07 miles away from her starting point if she plans to run straight back.

If the runner jogs 5 miles west and then 5 miles north, she forms a right triangle with the starting point as the right angle.

To find the distance from the starting point, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the distance jogged west and north are the two sides of the right triangle.

Let's label the distance jogged west as side A and the distance jogged north as side B.

Using the Pythagorean theorem, we have:

Hypotenuse^2 \(= A^2 + B^2\)

Hypotenuse^2 \(= 5^2 + 5^2\)

Hypotenuse^2 = 25 + 25

Hypotenuse^2 = 50

Taking the square root of both sides, we get:

Hypotenuse \(= \sqrt{(50)\)

Hypotenuse ≈ 7.07

Step-by-step explanation:

but it can be a cent off, so it might be wrong.

Simplifying the top:

(2* a^3 * b^5)^2 * (6ab)

4* a^6 *b^10 * (6ab)

24 *a^7 * b^11

so we have

(24 *a^7 * b^11) / (-3* a^5 *b)

immediately we can simplify 24 and -3

(-8 *a^7 * b^11) / ( a^5 *b)

a^7 and a^5 can cancel into just a^2

(-8 *a^2 * b^11) / (b)

b^11 and b cancels to b^10

-8 *a^2 * b^10

so that is your answer:

Step-by-step explanation:

Option 1 is generally the better choice for Jane because it offers a higher rate of return and compounds the interest, which means that the interest earned on the initial investment is also earning interest over time. This can lead to a significantly larger amount of money being earned in the long run compared to simple interest, which is only applied to the initial investment.

For example, if Jane invests $100 in an account that pays 5% compound interest per year, at the end of the first year she will have earned $5 in interest and will have a total of $105 in the account. If she leaves the money in the account for a second year, she will earn interest on the original $100 as well as the $5 in interest that was earned in the first year, resulting in a total of $110.25 at the end of the second year. This process continues year after year, resulting in a steadily growing amount of money.

On the other hand, if Jane chooses option 2 and invests her money in an account that pays simple interest at a rate of 6%, she will only earn interest on the initial investment of $100. For example, at the end of the first year, she will have earned $6 in interest and will have a total of $106 in the account. While this is still more than the amount she would have at the end of the first year with option 1, the difference between the two options becomes more pronounced over time as the compound interest continues to grow.

Overall, option 1 is the better choice for Jane because it offers a higher rate of return and compounds the interest, resulting in a larger amount of money being earned over time.

what is meant by rate of return?

The rate of return is the amount of money that an investment is expected to generate over a certain period of time. It is often expressed as a percentage of the initial investment. For example, if you invest $100 in an account that pays 5% interest per year, the rate of return on that investment is 5%.

Answer:

The answer is C :D

Step-by-step explanation:

Elena plans on running a total of 5 miles.

Mile, any of several distance measurements, such as the statutory mile (5,280 ft) (1.609 km). It comes from of the Romans lire passus, also referred as the "1000 steps," which was equal to 5,000 Romans feet. Unit of length is a related topic. See all relevant material The "old London" mile was eight furlongs when it was first established in 1500.

The term mille passus, which translates to "a hundred paces" in Latin and meant a length of 1,000 rates of speed or 5,000 Rome feet, was originally used by the Romans. It is equivalent to around 1,480 metres, or 1,618 contemporary yards.

We are aware that she has covered 2 miles, or 40% of a total distance, in her run thus far:

\(2=0.4x\)

To find x,

\(2=0.4x\)

\(x=\frac{2}{0.4}\)

The equations representing the functions and the values, domain and range  of the functions are presented as follows;

The amount to pay are;

Amount to pay, applying the 40 percent first = $62

Amount to pay applying the $10 coupon first = $66

The domain is the set of the possible input values of the function.

The percentage discount on all merchandise = 40 percent

The coupon amount received by mail = $10

The original price for the ;pair of shoes = $120

The amount paid, A, if the 40 percent discount is applied first can be found as follows;

A = 120 × (1 - 0.4) - 10 = 62

The amount paid if the 40 percent is applied first is $62

Amount paid if the coupon is applied first is found as follows;

A = (120 - 10) × (1 - 0.4) = 66

The amount paid if the $10 coupon is applied first is $66

The equations for the function f ang g are presented as follows;

f(x) = x × (1 - 0.4) = 0.6·x

g(x) = x - 10

Questions

g(f(120)) = g(0.6·x)

g(0.6·x) = 0.6·x - 10

x = 120

Therefore;

g(0.6·x) = 0.6 × 120 - 10 = 62

g(f(120)) = 62

The expression, f(g(120)) can be presented as follows;

f(g(120)) means that the $10 coupon is applied first before the 40 percent discount

f(g(120)) = f(120 - 10) = f(110)

f(110) = 0.6 × 110 = 66

f(g(120)) = 66

The values of the two expressions are different because percentage discount is larger and applied to the whole off the original or discounted price while the discount is a fixed amount subtracted from the original price or a percentage of the original price.

The possible input values for g(x)  are; 1, 2, 3, 4

The possible input values for h(x)  are; 0, 2, 4, 6

The possible output values for h(x)  are; 3, 5, 7, 9

The output values for g(x)  are; 0, 3, 6, 9

The points of the graph of g(h(x)) is therefore; (3, 6)

The domain is therefore; 3, and the range is 6

g(x) = x², h(x) = x - 3

The composite function, g ○ h(-4) = g(h(-4))

h(-4) = -4 - 3 = -7

f(x) gives us the average test score, so to calculate the average test score n your math class after test 2, we need to replace x by 2 in f(x), then:

Therefore, the test average for your math class is 79.4

Part B.

To find the test average for your science class after test 2, we need to know what is the value of g(x) when x is equal to 2.

Since g(x) is 84 when x is 2, the test average for your science class is 84.

Answer:

Step-by-step explanation:

To align his experimental results more closely with the theoretical probability, Jamie should increase the number of trials he performs when rolling the 6-sided die.

To make Jamie's experimental results more closely match the theoretical probability, he can increase the number of trials. By increasing the number of times he rolls the 6-sided die, Jamie can gather a larger sample size, which helps reduce the impact of random variations and provides a more accurate representation of the underlying probabilities.

The experimental probability is calculated by dividing the number of times an event occurs (in this case, rolling a 2) by the total number of trials. As Jamie increases the number of trials, the experimental probability tends to converge towards the theoretical probability.

Increasing the number of sides on the die or decreasing the number of trials would not necessarily improve the accuracy of Jamie's results. The theoretical probability is based on the assumption of a fair 6-sided die, so changing the number of sides would alter the theoretical probability.

Answer:

a. 90

b. 70

Step-by-step explanation:

What we need to do here is make substitutions for x.

We proceed as follows;

P(x) = 20cos60x + 80

x is the number of horses since 2009, so for 2010, x = 2010-2009 = 1

Substitute this;

P(x) = 20Cos60(1) + 80 = 20Cos60 + 80 = 10 + 80 = 90

Kindly recall that cos 60 = 0.5

For 2025, x = 2025 - 2009 = 16

Substitute this value;

P(x) = 20cos60(16) + 80

P(x) = 20cos960 + 80

Recall, cos960 = -0.5

P(x) = 20(-0.5) + 80

P(x) = -10 + 80

P(x) = 70

Answer:

$33.6667

Step-by-step explanation:

Given the following :

Number of Scarf designs = 6

Number of each made = 15

Total scarfs = (15 * 6) = 90

Cost:

Booth = $128

Production cost per scarf = $9.80

Total production cost = $9.80 * 90 = $882

Total cost = $128 + $882 = $1010

Break even = profit - loss = 0

One third of scarves = 1/3 * 90 = 30

This means he must cover for the total cost of $1010 after selling 30 scarves

Hence price per scarf will be :

$1010 / 30

= $33.6667

The equation 4x^3+10x^2 – 6x is factorized as 2x(x+3)(2x – 1).

Option B represents the correct factors of the equation.

A factor of the number can be defined as a divisor of the number that divides it completely without leaving any remainder.

Given equation is 4x^3+10x^2 – 6x. This can be factorized as given below.

\(4x^3+10x^2-6x = 0\)

We take the common term 2x, then,

\(2x ( 2x^2 + 5x -3)=0\)

\(2x ( 2x^2 +6x -x -3)=0\)

\(2x (2x (x+3) -1(x+3))=0\)

\(2x (2x-1)(x+3)=0\)

Hence we can conclude that the factors of the given equation are 2x(x+3)(2x – 1). Option B shows the correct factors.
