The random variable X has a uniform distribution with values between 16 and 24. What is the mean and standard deviation of X

Answers

Answer:

[tex]Mean = 20[/tex]

[tex]SD = 2.31[/tex]

Step-by-step explanation:

Given

[tex]a = 16[/tex]

[tex]b = 24[/tex]

Solving (a): The mean

The mean of a uniform distribution is:

[tex]Mean = \frac{1}{2}(a + b)[/tex]

This gives:

[tex]Mean = \frac{1}{2}(16 + 24)[/tex]

[tex]Mean = \frac{1}{2}(40)[/tex]

[tex]Mean = 20[/tex]

Solving (b): The standard deviation

The standard deviation is:

[tex]SD = \sqrt{\frac{(b - a)^2}{12}}[/tex]

This gives:

[tex]SD = \sqrt{\frac{(24 - 16)^2}{12}}[/tex]

[tex]SD = \sqrt{\frac{(8)^2}{12}}[/tex]

[tex]SD = \sqrt{\frac{64}{12}}[/tex]

[tex]SD = \sqrt{5.333}[/tex]

[tex]SD = 2.31[/tex]

The force, F (Newtons), between two objects is inversely proportional to the square of the distance, d (metres), between them.
The force is 0.006 Newtons when the distance between the objects is 4 metres.
Work out d (rounded to 2 DP) when F=0.045 Newtons.​

Answers

Answer:

d = 1.46 m

Step-by-step explanation:

We'll begin by obtaining the relationship between the force (F) and the distance (d). This can be obtained as follow:

From the question given above,

F is inversely proportional to square of d. This can be written as:

F ∝ 1/d²

F = K/d²

Cross multiply

K = Fd²

But:

Force (F) = 0.006 N

Distance (d) = 4 m

Constant (K) =?

K = Fd²

K = 0.006 × 4²

K = 0.006 × 16

K = 0.096 Nm²

Therefore, the relationship between the force (F) and the distance (d) is:

F = K/d²

F = 0.096 / d²

Finally, we shall determine the distance when the force is 0.045 N. This can be obtained as follow:

Force (F) = 0.045 N

Constant (K) = 0.096 Nm²

Distance (d) =?

F = K/d²

0.045 = 0.096 / d²

Cross multiply

0.045 × d² = 0.096

Divide both side by 0.045

d² = 0.096 / 0.045

Take the square root of both side.

d = √(0.096 / 0.045)

d = 1.46 m.

• How can the product of two whole numbers (e.g., 48
and 19) help us find the product of two decimals with
the same digits (e.g., 0.048 and 1.9)? Write your
explanation in the text box.

Answers

Let's say we already did the work and found the result of 48*19. That result is 912.

When it comes to multiplying 0.048 and 1.9, we're going to need to do two things to transform those numbers into 48 and 19.

Move the decimal point of 0.048 exactly three spaces to the right. This is the same as multiplying by 1000. So 1000*0.048 = 48

Move the decimal point of 1.9 exactly one space to the right. This is the same as multiplying by 10. So 10*1.9 = 19

Overall, we've multiplied by 1000*10 = 10,000. This means 48*19 = 912 is 10,000 times larger compared to the result of 0.048*1.9

To fix this, we need to divide by 10,000 to get 912/(10,000) = 0.0912

Dividing by 10,000 is the same as moving the decimal point to the left four spaces. Note how 10,000 = 10^4.

I recommend using your calculator to see that 0.048*1.9 = 0.0912 which matches with the previous result we got.

Answers

Answer:

lesser x = -2

greater x = 2

Step-by-step explanation:

The values of a function f(x) are the values of x for which f(x) = 0.

In this question:

[tex]f(x) = 5x^2 - 20[/tex]

So, finding the zeros:

[tex]5x^2 - 20 = 0[/tex]

[tex]5x^2 = 20[/tex]

[tex]x^2 = \frac{20}{5}[/tex]

[tex]x^2 = 4[/tex]

[tex]x = \pm \sqrt{4}[/tex]

[tex]x = \pm 2[/tex]

So

lesser x = -2

greater x = 2

Answer:

Inequality: [tex]435 + d \geq 815[/tex]

Solution: [tex]d \geq 380[/tex]

Step-by-step explanation:

He has 435 stamps in his collections.

He will collect d stamps, and he wants to collect at least 815 stamps, that is, the sum of 435 and d has to be at least 815.

So the inequality is given by:

[tex]435 + d \geq 815[/tex]

And the answer is given by:

[tex]d \geq 815 - 435[/tex]

[tex]d \geq 380[/tex]
