Answer:

Dependent Event

Step-by-step explanation:

Assume that are 10 balls, such that:

[tex]Red = 6[/tex]

[tex]Green = 4[/tex]

If the balls are replaced after taken, the probability is:

[tex]Pr(Red) = 6/10[/tex]

[tex]Pr(Green) = 4/10[/tex]

This is referred to as independent event; because each selection do not affect the next or previous selection

However, if the balls are not replaced, the probability is:

[tex]Pr(Red) = 6/10[/tex]

[tex]Pr(Green) = 5/(10 - 1) = 5/9[/tex]

We subtracted 1 because there is a reduction in the number of balls when the red ball is not returned.

This is referred to as independent event; because a selection affects the next selection

Answer:

Get a ruler

Step-by-step explanation:

I can't really answer this because it's a measuring problem.

But I'll walk you through it.

First, grab your ruler. Once you have it, you're gonna measure the icon, so the  square picture. Make sure you measure it in centimeters (cm). Measure EACH side. Once you have the measurement of each sides, add them up to get your perimeter. The perimeter will always be length + width + length + width.

To find the area, take your length and your width and multiply them together.

For the second problem, you're going to take your measured side and multiply EACH of them by 2.5. The scale 1 cm = 2.5 mm means that for every represented centimeter in the image, the actual image is 2.5 mm. Once you have multiplied each sides by 2.5, you're going to repeat the steps above to get the perimeter and the area.

Answer:

Arc ABC = 250°

Step-by-step explanation:

m<AOB = 110° (given)

Based on the central angle theorem, central angle m<AOB equals the intercepted arc AB

Therefore,

m<AOB = measure of arc AB = 110°

Thus:

Arc ABC = 360° - arc AB (Full circle = 360°)

Arc ABC = 360° - 110°

Arc ABC = 250°

Answer:

$2655 + $324d

Step-by-step explanation:

total cost of a booth = fixed cost + (variable cost x number of days)

Fixed costs are costs that do not vary with output

Variable costs are costs that vary with production

cost of 18 food booths = 18(50 + 6d) = 900 + 108d

cost of 27 game booths = 27(65 + 8d) = 1755 + 216d

Add the total cost of the food and game booths together 900 + 1755 = 2655

108d + 216d = 324d

Answer:

7.25

Step-by-step explanation:

Given :

___________ Sample size __ sample mean

Treatment 1 ____ 5 _______ 4

Treatment 2 ____ 10 ______ 8

Treatment 3 ____ 5 _______ 9

Sample size = (5 + 10 + 5). = 20

Overall mean = ((5*4). + (10*8) + (5*9)) / 20

Overall mean = (20 + 80 + 45) / 20

= 145 / 20

= 7.25

Answer:

23

Step-by-step explanation:

Women total age = 5 x 23 = 115

Men total age = 3 x 24 = 72

The mean age of all the people

= (115+72)÷(8)

= 23.375

= 23 (nearest year)

The mean age (nearest year) of all the people in the office is 23

The given parameters are:

5 women = 23 years

3 men = 24 years

Mean is calculated using:

[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]

So, we have:

[tex]\bar x = \frac{23 * 5 + 24 * 3}{5 + 3}[/tex]

Evaluate the quotient

[tex]\bar x = 23[/tex]

Hence, the mean age (nearest year) of all the people in the office is 23

Answer:

y = 1/2 x - 2

Step-by-step explanation:

The standard linear equationof a line is expressed as y = mx+b

Using the coordinate points (0, -2) and (2, -1)

Slope m = -1-(-2)/2-0

m = -1+2/2

m = 1/2

Since the line cuts the y axis sat y = -2, hence the intercept b = -2

Get the required equation;

Recall that y = mx+b

y = 1/2 x + (-2)

y = 1/2 x - 2

This give the required linear equation

Answer:

A = $20,940

Step-by-step explanation:

Interest = Principal x Rate x Time

I = prt

I = 15000(.018)(22)

I = 5940

Interest = $5,940

Total Amount = Principal + Interest

A = P + I

A = 15000 + 5940

A = 20940

Answer:

85% or 99.85%

Step-by-step explanation:

If you mean 15% by 0.15 then the probability that it will not rain is 85% because, 100-15=85.

If you mean 0.15% by 0.15 then the probability that it will not rain is 99.85% because, 100-0.15 is 99.85.

Answer: They can form one triangle.

Step-by-step explanation: Since all triangle must have 180 degrees, there’s only one set of degrees that sum up to 180.

28+51+101=180

I’m sorry, but the feet/centimeters part you have to solve on your own. Remember, this is a learning community! No stress :) I can guarantee you won’t get it wrong though.

There’s many different triangles, and I’m sure from these feet/centimeters you can make at least one of the listed: Scalene (none of the sides are equal), isosceles (only 2 sides are equal) or equilateral triangle (all sides are equal). There’s also right triangles (which are triangles with one right angle also known as 90 degrees) that are either isosceles or scalene or both! Try your best and remember, no stress :)

Answer:

E because is covered all angle

< DCE ≅ < GCF must be true

Hence Option A and E are true statements.

A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around. In that case, the sector has 1/6 the area of the whole circle.

According to the given figure:

DE ≅ FG

So < DCE ≅ < GCF must be true

Because DE ≅ FG

< DCE ≅ <GCF is similar to DE ≅ FG

Hence, < DCE ≅ < GCF must be true

Hence Option A and E are true statements.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

The area of the living room wall = The area of the rectangle

The amount of paint needed to cover one wall is 240 square feet.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

Example:

The area of a rectangle with length 2cm and width 3cm is 6cm².

We have,

A living room wall is 20 feet long, and 12 feet high.

The living room can be considered a rectangle.

Length = 20 feet

Width = 12 feet

The area of the living room wall = Area of a rectangle

Now,

Area of the living room wall.

= 20 x 12

= 240 square feet

Thus,

The amount of paint needed to cover one wall is 240 square feet.

#SPJ5

Answer:

83 degrees

Step-by-step explanation:

We can use the consecutive angle theorem to find the the value of x.

We can do that by doing 5x+10.5+6x+10 = 180

After simplifying, we get 11x+20.5=180

Subtract 20.5 on both sides and you get 11x=159.5.

Divide by 11 on both sides and you get x=14.5

Now we can use opposite angle theorem and set angle N and angle T equal.

That means we could write 5x+10.5 = m<T

We can substitute 14.5 for x and we get 72.5+10.5 = m<T

Simplify and you get 83 = m<T
