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:

Answer:

(6, 1)

Step-by-step explanation:

x + 3y = 9

x + 4y = 10

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

-1 (x + 3y = 9)

-x - 3y = -9

x + 4y = 10

      1y = 1  or y =1

x + 4y = 10

x + 4(1) = 10

x + 4 = 10

Answer:

$422.50

Step-by-step explanation:

If the bike is marked down by 35% then the final sale price will be 65% of the original price (since 100% - 35% = 65%).

Convert 65% into a decimal:  65% = 65/100 = 0.65

Therefore, 65% of $650 = 0.65 × 650 = $422.50

We need first mark downed amount

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

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.

Answer:

Line u shows the movement of the ladybug. Because line v goes farther than line u

Step-by-step explanation:

Because line v goes farther than line u

The ladybug's motion is depicted in line u. Because line v is moving farther than line u.

The amount of the shift in approach per unit of time or the size of the displacement over time for an object can be used to describe speed, which would be a scalar quantity in everyday language and kinematics.

The maximum speed that can be maintained when a period grows closer to zero is the starting speed.

By dividing the object's distance traveled by the duration of the interval, the mean pace of the object for the given period is calculated. Speed and velocity are not always the same thing.

The line u and v show the position of the two bugs, but the line that shows the ladybug's movement is line u because line v is moving farther than line u.

If the scale I make for the parking lot is 10 inches long, it should be 7.5 inches wide.

Scale is a term to refer to a drawing and design method in which an object or space and its actual measurements are taken as a reference and subsequently reduced or increased while maintaining the proportions between their measurements.

To calculate the width of the parking lot to scale, it is necessary to perform the following mathematical operation.

We need to figure out how much 100 yards is on the inch scale model. So if 400 yards is 10 inches we must divide this value by 4 as shown below:

Based on the above, 100 yards equals 2.5 inches on this model. So if your width is 300 yards, the length in inches would be 7.5 inches.

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: 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.

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.

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.
