There are 362,880 ways to ducklings line up.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A mother duck lines her 9 ducklings up behind her.

Now,

Since, A mother duck lines her 9 ducklings up behind her.

Hence, By using Fundamental counting principal we get;

The number of ways for ducklings line up = 9!

                                                                 = 9×8×7×6×5×4×3×2×1

                                                                 = 362,880

Thus, The number of ways for ducklings line up = 362,880

The probability that Andy chooses a striped shirt and a pair of blue shorts is:

[tex]\frac{3}{4} * \frac{1}{3} = \frac{3}{12} = \frac{1}{4}[/tex]

The probability that Andy chooses a striped shirt and pair of tan or plaid shorts is:

[tex]\frac{3}{4} * (\frac{1}{3} + \frac{1}{3}) = \frac{6}{12} = \frac{1}{2}[/tex]

If triangle ABC is equilateral then the value of x is 3.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

ABC is an equilateral triangle.

AD is the perpendicular bisector of CB

As AC=8 units.

The other sides of triangle will be also 8 units.

D will be the midpoint of CB.

CD=4 units and DB is 4 units.

Let us consider triangle ACD

AC²=CD²+AD²

8²=4²+x²

64=16+x²

Substitute 16 from both sides.

64-16=x²

48=x²

Take square root on both sides.

x=√48

=√16×3

=4√3

Hence, if triangle ABC is equilateral then the value of x is 3.

Answer:

Cherry ice cream contains 19.75 grams of fat

Mint chocolate chunk ice cream contains 6.75 grams of fat.

Step-by-step explanation:

From the given question,

3C + 1M = 66 ............. 1

1C + 3 M = 70 ........... 2

Multiply equation 1 by 1, and 2 by 3 to have,

3C + 1M = 66

3C + 9 M = 210

Subtract,

1 M - 9 M = 66 - 210

-8 M = -54

Divide through by -8 to have,

M = 6.75

Substitute the value of M in equation 1,

3C + 1(6-75) = 66

3C = 66 - 6.75

3C = 59.25

C = 19.75

Thus,

1 scoop of the Cherry ice cream contains 19.75 grams of fat, while 1 scoop of the Mint chocolate chunk ice cream contains 6.75 grams of fat.

Step-by-step explanation:

The expression that should represent the cost of the sweatshirt involving sales tax is given below

Since it is given that the cost of the sweatshirt be n dollars

And, the sale tax is 8%

So, the expression should be

= n + n × 0.08

= n + 0.08n

Hence, the expression is n + 0.08n

Answer:

The answer is a and d

Step-by-step explanation:

The simple interest shows linear growth because it is adding a constant amount.

The compound interest shows exponential growth because it is multiplying by a constant amount.

"Simple interest can be defined as the sum paid back for using the borrowed money, over a fixed period of time."

"Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest."

Here the principle amount is $100.

Simple interest rate is 7%.

Compound interest is 5% compounded quarterly.

After 5 years, with simple interest, the amount will be

= $[100 + (100 × 7 × 5)/100]

= $[100 + 35]

The simple interest shows linear growth because it is adding a constant amount.

After 5 years, with compound interest, the amount will be

= $[100(1 + 0.05/4)⁴⁽⁵⁾]

= $[100(1 + 0.0125)²⁰]

= $[100(1.0125)²⁰]

Therefore, the compound interest shows exponential growth because it is multiplying by a constant amount.

Answer:

600 sq.ft.

Step-by-step explanation:

10 * 24 = 240 / 2 = 120

20*24 = 480

480+120 = 600

600 sq.ft.

Answer:

720

Step-by-step explanation:

So there are two things you need to remember to sovle this problem.

First, the formula for area of a square. This is just base x height.

Second, the formula for area of a triangle. THis is just 1/2 x base x height.

Lets plug our values into both formulas and see what we get.

So the area of the square would be:

24 x 20.

This is 480.

Now that we know the area of the square is 480, lets find the area of the traingle:

1/2 x 24 x 20

This will get you 240.

Low lets just add the two together, and we get:

240+480=720

So the area is:

720

Step-by-step explanation:

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.

Variance =9.2983, 27.6927

Standard deviation = 3.0493, 5.2624

Step-by-step explanation:

n = 20

S = 14.75

X² = chisquare

N-1 = degree of freedom

Alpha = 0.1

Alpha/2 = 0.1/2 = 0.05

1-0.1/2 = 0.95

Using statistics table

X² 19,0.05 = 30.14

X² 19, 0.95 = 10.12

A. 19(14.75)/30.14 , 19(14 75)/10.12

= 9.2983, 27.6927 for the variance of the population

B. Standard deviation = square root of variance

= √9.2983, √27.6927

= 3.0493, 5.2624

The population of bacteria in the culture after 7 hours, to the nearest whole number is 27,971 bacteria

In order to determine the figure of the population of bacteria in the culture after 7 hours, to the nearest whole number, we make use of the formula:

P_t = P_0\cdot 2^{\frac{t}{d}}P t =P 0 ⋅2 d t

We know that P_0 = 8600, t = 7, and d = 5. Plugging these values into the formula, we get:

P_t = 8600 * 2^(7/5)

To find the population after 7 hours, we can calculate the value of this expression. To the nearest whole number, the population is approximately 27,971 bacteria.

Therefore, the size of the population after 7 hours is 27,971 bacteria.
