A piece of stone art is shaped like a sphere with a radius of 4 feet. What is the volume of this sphere? Let π≈3.14
π
≈
3.14
. Round the answer to the nearest tenth.

Answer:

Linear: y = 2x-1

Step-by-step explanation:

slope 1 = (5 - -9)/(3 - -4) = 14/7 = 2

slope 2 = (19-5)/(10-3) = 14/7 = 2

equation: y = mx + b          b = y-mx = 19 - 2*10 = -1

y = 2x - 1

Complete Question:

Allie is going to select a card from the group of cards shown.

Because the probability that each number will be selected is not _______, the group of cards is not fair.

See attachment for cards

Answer:

Because the probability that each number will be selected is not equal, the group of cards is not fair.

Step-by-step explanation:

Given

From the attachments, the cards are:

[tex]Cards: [1]\ [3]\ [5]\ [1]\ [5]\ [5]\ [3]\ [2]\ [5]\ [5][/tex]

Required

Fill in the gaps

The question asks if the game is fair or not.

So, first, we need to get the frequency of each card number.

This is shown below:

[tex]Cards\ \ Frequency[/tex]

[tex]1[/tex]            [tex]2[/tex]

[tex]2[/tex]            [tex]1[/tex]

[tex]3[/tex]            [tex]2[/tex]

[tex]5[/tex]            [tex]5[/tex]

[tex]Total[/tex]      [tex]10[/tex]

From the above frequency table, each card do not have the same frequency.

This implies that the probability of selecting each card is not equal (i.e. not the same).

Hence, it is not fair.

Answer:

I think it is D because it's just gas

Step-by-step explanation:

Answer:

Vertex: (5,-4)

Axis of symmetry: x=5

X-intercepts: (3,0) and (7,0)

Y-intercept: (0,21)

Step-by-step explanation:

The vertex would be the tip of the parabola, so the vertex is (5,-4)

The axis of symmetry would be a line cutting a parabola in half indicated by the line x=5

X-intercepts are where a function passes through the x-axis or when y=0, so in this case, the x-intercepts are (3,0) and (7,0)

The y-intercept of a function is where a function passes through the y-axis or when x=0, so our y-intercept is f(0)=0²-10(0)+21=21, or (0,21)

Answer:

130

Step-by-step explanation:

Answer:

x = 95°

Step-by-step explanation:

∡5 = 50° because it's vertical with the angle labeled as 50°

∡6 = 130° because it is supplementary with ∡5

∡6 ≅ ∡2 because they are corresponding angles

∡2 + (x-45) = 180 because they are supplementary

130 + x - 45 = 180

x + 85 = 180

x = 95°

Answer:

24 feets

Step-by-step explanation:

Area of a trapezium :

A=1/2(b1+b2)h

b1 = 30 ; b2 = 50 ; Area, A = 960ft²

Inputting values into the formula :

960 = 1/2(30 + 50) * h

960 = 1/2(80)h

960 * 2 = 80h

1920 = 80h

Divide both sides by 80

1920 / 80 = 80h / 80

24 = h

Height of backyard = 24 feets

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Principal (P)= $2,500

Interest rate= 4%

Number of periods= 2 years

First, we will determine the interest earned using the simple interest formula:

I= P*r*t

I= 2,500*0.04*2

I=$200

Now, using the compound interest formula:

I= [P*(1 + r)^t] - P

r= 0.04/2= 0.02 (semi annual interest rate)

t=2*2= 4 semesters

I= [2,500*(1.02^4)] - 2,500

I= $206.08

Answer:

$206.08

Biased

Step-by-step explanation:

Hi there,

Since people at a football game are asked what their favorite sport is, it is more than likely that it would be football since they attend a game they are interested in. In other words, it is usually given that people at a football game like football. Therefore, the responses would be biased.

Hope this explanation helps.

Cheers.

Answer:

16767

Step-by-step explanation:

Each new term is found by multiplying the previous term by 3.  Thus, 3 is the common ratio.  The formula for this geometric series is therefore

a(n) = 23*3^(n - 1).

The 7th term is a(7) = 23*3^6 = 16767

Answer: <

6.12 x 10^4 < 612,000

Step-by-step explanation:

Answer:

<

Step-by-step explanation:

because 6.12 × 10^4 = 61,200 and 612,000 is obviously a way bigger number, so greater than symbol is the correct answer.

Answer:

The equation representing the situation is;

36 = 3·y + 4·x

Step-by-step explanation:

The structures the gardener is planning to build = Equally-sized sections of flower bed

The length of wood the gardener has to surround both gardens = 36 feet

The perimeter of the entire garden, P = 2·y + 2 × 2·x

The length of the wood separating the two gardens = The length of the side 'y'

The perimeter of the garden and the length of the fence separating the two gardens = P + y = 2·y + 2 × 2·x + y = 3·y + 4·x

Therefore the length of wood available, 36 feet, will be used for a length equivalent to P + y

∴ 36 = P + y = 3·y + 4·x

∴ 36 = 3·y + 4·x

The equation representing the situation is 36 = 3·y + 4·x.

Answer:

The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure.

Step-by-step explanation:

AD is 9 units long

A’D’ is 3 units long.

Scale factor is A’D’ / AD

Scale factor = 3/9 = 1/3

Answer:

Step-by-step explanation:

X=5      2x+y=10

you already have x

just need to find y

2x+ y=10

2 (5)+y=10

10 + y=10

y=10- 10 ( when you change the number place the sign should change too, if it was - it will turn +)

y=10-10

y=0
