Michael made a spinner to use in a game. He tested the spinner by spinning it 4 times. The pointer landed on 1 each time. What do these results suggest about the spinner?

A. It is probably a fair spinner. The probability of spinning a “1” is 0.25.


B. It is probably a fair spinner. The probability of spinning a “1” 4 times is 0.25 × 4, which equals 1.


C. It is probably not a fair spinner. The probability of spinning a “1” on all 4 spins is about 0.004.


D. It is probably not a fair spinner. The probability of spinning a “1” on all 4 spins is less than 0.0001.

Please help

Answers

Answer 1

Answer:

C

Step-by-step explanation:

If  The probability of spinning a “1” is 0.25, then the probability of spinning 4 ones is:

0.25*0.25*0.25*0.25 = 0.25^4 ≈ 0.004

(the four events are independent)

The pointer landed on 1 each time, which probability is very low. So, we can conclude that the spinner is not fair.

What is the volume of the cylinder? Use 3.14 for π, and round your answer to the nearest tenth. Enter your answer in the box.

Answers

Answer:

The equation to solve the volume of a cylindar is Pie times the radius squared times the height of the cylindar. The radius is distance from the center of the circle outwards.

Answer:

The answer is 235.5

Step-by-step explanation:

On a coordinate plane, a circle has a center at (0, 0). Point (0, negative 5) lies on the circle. The point (0, 5) lies on a circle that is centered at the origin. Does (–3, –4) also lie on the circle? Identify the radius from the graph. r = __units Determine the distance from the center to (–3, –4) using the distance formula. distance =___ units Compare the radius to the distance. Does the point (–3, –4) also lie on the circle?

Answers

we know thatthe equation of a circle is(x-h)²+(y-k)²=r²where the center is the point (h,k)r is the radius if the center is the originso(h,k) is (0,0)the radius is the distance from point (0,5) to the origin (0,0)r=√[(-5)²+(0)²]-------> r=√25---------> r=5 unitsthe equation is(x-h)²+(y-k)²=r²------------> (x-0)²+(y-0)²=5²----------> (x)²+(y)²=25Does the point (–3, –4) also lie on the circle?the distance from the center to (–3, –4) isd=√[(-4)²+(-3)²]-------> d=√25--------->d=5 unitsd=rthereforethe point (-3,-4) also lie on the circle

The point (–3, –4) does lie on the circle with a center at (0, 0).

We know that the point (0, 5) lies on the circle, and since the center is at (0, 0), the distance from the center to (0, 5) gives us the radius.

Using the distance formula:

radius = √((0 - 0)² + (5 - 0)²)

= √0+25

=√25

= 5 units

So, the radius of the circle is 5 units.

Next, let's determine the distance from the center (0, 0) to the point (–3, –4) using the distance formula:

distance = √ (0- (-3))²+ (0-4(-4))²

= √ 3² + 4²

= √9 +16

= √25

= 5 units

The distance from the center to (–3, –4) is also 5 units.

Since the distance from the center to (–3, –4) is equal to the radius of the circle, the point (–3, –4) lies on the circle.

Therefore, the point (–3, –4) does lie on the circle with a center at (0, 0).

Kiyo is designing a rectangular garden with a 2-ft wide path all the way around it. The length of the garden is 3 times as long as the width. Kiyo models the area of his garden and the path with the equation f(x) = (x + 2)(3x + 2). Explain Kiyo’s error

Answers

Answer:

The correct equation that models the area if x(3x) or 3x² where x is the width of the path

Step-by-step explanation:

Area of a rectangle = Length *Width

Width of the rectangular garden W = 2ft

If the length of the garden is 3 times as long as the width, then length = 3 * width i.e W = 3L

Since Area of the path A = L* W

A = (3W)W

A = 3W²

If the width is the same as x then

Area f(x) = (3x)(x)

According to kyle, the area of his path f(x) = (x + 2)(3x + 2) which is wrong because of kyle addition of 2 to each of the value of the length and width respectively which kyle shouldn't have added any value to the dimension to the garden

An office and apartment building is made up of modules. Each module is a rectangular prism. The building has 150 modules, and is 15 stories high. If all of the modules were divided evenly among the number of stories, how many modules would be on each floor? How many different rectangular prisms could be made from that number? If all of the modules were divided evenly there would be modules on each floor. different rectangular prisms could be made from the number of modules on each floor: × 1 × 1 and 2 × × 1.

Answers

Answer:

Part 1. 10 modules per floor

Part 2. Two different rectangular prism

Step-by-step explanation:

Let

x ----> the number of modules

y ---> the number of stories

we have

x=150\ modules\\y=15\ stories

Divide the number of modules by the number of stories

so

\frac{x}{y}=\frac{150}{15}=10\ \frac{modules}{floor}

Marvin is painting three squares shaped like the one below if it takes him exactly 4 cans of paint to paint square 3 five cans of paint to paint square to how many cans of paint should he need to paint square one

Answers

Complete question:

Marvin is painting three squares shaped like the one below if it takes him exactly 4 cans of paint to paint square 3, five cans of paint to paint square 2 to how many cans of paint should he need to paint square one

Picture of squares is attached.

Answer:

9 cans of paint.

To paint square 1, he needs 9 cans of paint.

Step-by-step explanation:

Given that to paint square 3, four cans of paint are needed.

Therefore, let's take area of the square 3 as 4.

i.e a² = 4

Solving further, we have :

[tex] a = \sqrt{4} [/tex]

a = 2

We can say, each side of square 3 = 2 units

To paint square 2, five cans of paint are needed. Let's take the area of 2 to be 5.

i.e b² = 5

Solving further, we have :

[tex] b = \sqrt{5} [/tex]

We can say, each side of square 2 = [tex] \sqrt{5} [/tex] units

Using Pythagoras theorem, we have that the area of the square of a hypotenuse in a 90° angle is equal to the sum of the areas of the other two squares.

Therefore,

[tex] h^2 = 2^2 + \sqrt{5}^2 [/tex]

h² = 4 + 5

[tex] h = \sqrt{9} [/tex]

h = 3 units.

We now know one side of the square 1 is 3 units.

Area of square 1 = 3²

Area = 9.

Therefore to paint square 1, he needs 9 cans of paint.
