Answer: a. 0.00032    B. 0.00672

Step-by-step explanation:

Given: Proportion of  island residents of a country have reduced their electricity usage (p) = 20%= 0.20

Here, residents have two choices either reduced electricity usage or not , hence it follows binomial distribution

Let X be a binomial variable that represents the number of successes .

Binomial distribution formula:

[tex]P(X)=^nC_xp^x(1-p)^{n-x}[/tex], n= sample size.

a.

[tex]P(X=5) = ^5C_5(0.20)^5(1-0.20)^{5-5}=(1)(0.20)^5(1)\\\\=0.00032[/tex]

b. [tex]P(X\geq4)=P(4)+P(5)[/tex]

[tex]^5C_4(0.20)^4(1-0.20)^{5-4}+0.00032\\\\=(5)(0.20)^4(0.80)+0.00032\\\\=0.0064+0.00032\\\\=0.00672[/tex]

Answer:

you need to use the midpoint formula

Answer:

MN is [-3,2] sorry but not really sure about this because they are just two points and don't seem as segment.But when it asks for MN I don't know what to say else.

and midpoint of MN is -1/2

because

x=(x1+x2)/2=(-3+2)/2=-1/2

Answer: Anything between 0 and 10, excluding both endpoints.

In terms of symbols we can say 0 < w < 10 where w is the width.

===================================================

Explanation:

You could do this with two variables, but I think it's easier to instead use one variable only. This is because the length is dependent on what you pick for the width.

w = width

2w = twice the width

2w-5 = five less than twice the width = length

So,

which lead to

area = length*width

area = (2w-5)*w

area = 2w^2-5w

area < 150

2w^2 - 5w < 150

2w^2 - 5w - 150 < 0

To solve this inequality, we will solve the equation 2w^2-5w-150 = 0

Use the quadratic formula. Plug in a = 2, b = -5, c = -150

[tex]w = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\w = \frac{-(-5)\pm\sqrt{(-5)^2-4(2)(-150)}}{2(2)}\\\\w = \frac{5\pm\sqrt{1225}}{4}\\\\w = \frac{5\pm35}{4}\\\\w = \frac{5+35}{4} \ \text{ or } \ w = \frac{5-35}{4}\\\\w = \frac{40}{4} \ \text{ or } \ w = \frac{-30}{4}\\\\w = 10 \ \text{ or } \ w = -7.5\\\\[/tex]

Ignore the negative solution as it makes no sense to have a negative width.

The only practical root is w = 10.

If w = 10 feet, then the area = 2w^2-5w results in 150 square feet.

----------------------

Based on that root, we need to try a sample value that is to the left of it.

Let's say we try w = 5.

2w^2 - 5w < 150

2*5^2 - 5*5 < 150

25 < 150 ... which is true

This shows that if 0 < w < 10, then 2w^2-5w < 150 is true.

Now try something to the right of 10. I'll pick w = 15

2w^2 - 5w < 150

2*15^2 - 5*15 < 150

375 < 150 ... which is false

It means w > 10 leads to 2w^2-5w < 150  being false.

Therefore w > 10 isn't allowed if we want 2w^2-5w < 150 to be true.

Answer:

There are 2.5 grams of niacin contained in the bottle.

First you have to find how many milligrams are in the bottle.

So you multiply 125 by 20 since there are 125 tablets and 20 milligrams in each one.

125*20=2500

So there are 2500 milligrams in the bottle. Then you have to convert it into grams. To do that you divide the mass by 1000.

2500/1000=2.5

So there are 2.5 grams in the bottle.

Step-by-step explanation: hope this helps :)

Answer:

change numbers

1, 500, 000 + 4 per

sell for 75 per

x = each sneaker

1, 500, 000 + 4 x

sell for 75 x

we want to sell 15, 000

put 15, 000 where x is

1, 500, 000 + 4 (15, 000)

sell for 75 (15, 000)

1, 500, 000 + 4 × 15, 000 = 1, 560, 000

sell for 75 × 15, 000 = 1125000

minus the amount to make sneakers from amount getting for the sneakers

loss = ?

Answer:

Step-by-step explanation:

It is a little vague on what the expected answer is. But for quadrilaterals, any rotational symmetry will be along a line that divides the quadrilaterals in two equal halves. This is due to symmetry.

Also the two equal halves will be mirror image of each other at the axis of symmetry. It is again due to properties of symmetry.

Lastly rotating a quadrilateral along its axis of rotational symmetry will create a 3-D cylindrical shape. A cross-section of that shape along the axis will show the same quadrilateral.

If triangle ABC is reflected across the x axis, the new point is A'(-3, -2), B'(0, -1) and C'(-2, 3)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Triangle ABC has vertices A(-3,2) B(0,1) and C(-2,-3).

Step-by-step explanation:

I dont fully know if i am correct but i think its this:

p + r = 22

9p + 6r = 180

p = 22 - r

9(22 - r) + 6r = 180

198 - 9r + 6r = 180

-3r = -18

r = 6

p = 22 - 6

p = 16

Answer:

You have earned $67.50

Step-by-step explanation:

Since we are working with simple interest, we will use this formula:

[tex]I=Prt[/tex],

where P represents the principal amount (your deposit), r represents the rate as a decimal, and t represents the time in years. First, we need to rewrite our interest as a decimal by dividing 3% by 100:

[tex]3\div 100 = 0.03[/tex]

Now, we also know the values of P and t from the problem:

[tex]P=750\\r=0.03\\t=3[/tex]

We can substitute those values into the formula:

[tex]I=750(0.03)(3)\\I=67.5[/tex]

In context, that means you earned $67.50 in interest.

We will see that the length of the minute hand is 9.6 cm.

We know that for a circle of radius R, the length of the arc defined by an angle of θ is:

L = θ*R

In this case, the length of the arc is 15 cm, and the angle is the one between 1:15 and 1:30, which is one-fourth of a complete circle.

If a complete circle has an angle of 2pi, then one-fourth of a circle has an angle θ = (2pi)/4 = pi/2

Then, replacing the length of the arc and the angle we have:

15cm = (pi/2)*R

Now we can solve this for R, remember that pi = 3.14:

(15 cm)*(2/3.14) = R = 9.6cm

So the length of the minute hand is 9.6 cm.

So the correct option is the second one.
