Answers

Answer step-by-step

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

What is Trigonometry?

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.

A sample of size 20 from a normal distribution has sample mean 3.5 and sample variance 14.75. Find 90% confidence intervals for the variance and standard deviation of the distribution.

Answers

Answer:

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

Monique and Tara each make an ice-cream sundae. Monique gets 3 scoops of Cherry ice-cream and 1 scoop of Mint Chocolate Chunk ice-cream for a total of 66 of fat. Tara has 1 scoop of Cherry and 3 scoops of Mint Chocolate Chunk for a total of 70 of fat. How many grams of fat does 1 scoop of each type of ice cream have?

Answers

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.

A culture of bacteria has an initial population of 8600 bacteria and doubles every 5 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t ​ =P 0 ​ ⋅2 d t ​ , where P_tP t ​ is the population after t hours, P_0P 0 ​ is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 7 hours, to the nearest whole number?

Answers

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

How do we determine the population of the 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.

Solution: 362,880 possibilities

There are 362,880 ways to ducklings line up.

What is Multiplication?

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

Beth has $100 to invest. She can invest this into a 7% simple interest account or into an account with 5% interest compounded quarterly. The table shows the amount that would be in each account over the first five years. Which of the following statements are true about the growth shown in the table? The simple interest shows linear growth because it is adding a constant amount. The simple interest shows exponential growth because it is adding a constant amount. The compound interest shows linear growth because it is multiplying by a constant amount. The compound interest shows exponential growth because it is multiplying by a constant amount.

Answers

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.

What is simple interest?

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

What is compound interest?

"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.

Step-by-step explanation:

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
