When buying a candy bar, there is a 20% chance that it will also include a coupon for a second candy bar. A student wants to determine the probability that, if she buys 7 candy bars, more than 2 will include a coupon. To do this, she uses a random number table to pick 7 numbers from 1 to 5. She lets 1 represent a candy bar with a coupon and numbers 2 through 5 represent a candy bar without a coupon.. She repeats this for a total of 16 trials. The results are shown in the table.

Answer:

Volume = lbh

Volume = 7 × 5 × 6

Volume = 7 × 30

Volume = 210 mm³

Therefore

Volume is 210 mm³

[tex] \\ [/tex]

[tex] \bullet [/tex] Length (l) of the cuboid = 7mm

[tex] \bullet [/tex] Breadth (b) of the cuboid = 5mm

[tex] \bullet [/tex] Height (h) of the cuboid = 6mm

The volume of the cuboid.

We know the formula of the volume of the cuboid is ( Length × Breadth × Height ) cubic units.

[tex] \therefore [/tex] Volume of the cuboid is ( 7 × 5 × 6 ) mm³

Volume of the cuboid is 210 mm³.

Answer:

3^2 + 11^2 = 130

7^2 + 9^2 = 130

---

1^2 + 18^2 = 325

6^2 + 17^2 = 325

Step-by-step explanation:

We want to express 130 and 325 as the sum of two squares in two different ways.

Then, we want to find two integers a and b such that:

a^2 + b^2 = 130

There is not an analytical way to do this, we just need to try with different integers.

Let's start with 130.

So we start by defining a as a really small integer, for example 1, and try to find b.

1^2 + b^2 = 130

b^2 = 130 - 1

b^2 = √129 = 11.3

This is not an integer, so let's try with another value of a.

a = 2

2^2 + b^2 = 130

4 + b^2 = 130

b^2 = 130 - 4

b = √126 = 11.2

This can be discarded again.

Now let's try with a = 3

3^2 + b^2 = 130

9 + b^2 = 130

b^2 = 130 - 9

b = √121 = 11

Nice.

So we can express 130 as:

3^2 + 11^2 = 130

Now let's find another pair.

In the same way, we can see that for a = 7 we get:

7^2 + b^2 = 130

42 + b^2 = 130

b^2 = 130 - 49

b = √81 = 9

Then we can write:

7^2 + 9^2 = 130

Now for 325:

With the same reasoning than before, we want to find two integers such that:

a^2 + b^2 = 325

Then we start evaluating a by the smallest values:

a = 1

1^2 + b^2 = 325

b^2 = 325 - 1 = 324

b = √324 = 18

Then we can write 325 as:

1^2 + 18^2 = 325

Now to find the next pair we need to keep testing values for a, we will get for a = 6:

6^2 + b^2 = 325

36 + b^2 = 325

b^2 = 325 - 36 = 289

b = √289 = 17

Then we can write:

6^2 + 17^2 = 325.

Answer:

7.3

Step-by-step explanation:

Order of operations rules require that any work inside parentheses be done first.  Thus,

(4 + 2) - 1 + (2.3) becomes 6 - 1 + 2.3

This, in turn, becomes 5 + 2.3, and the final result is 7.3.

Respuesta:

79.4 pies

Explicación paso a paso:

Dado que :

Longitud del autobús = 33,5 pies

Longitud del tren = 45,9 pies más largo que el autobús

Por lo tanto, la longitud del tren es igual a:

Longitud del bus + 45,9 pies

33,5 pies + 45,9 pies

Longitud del tren = 79,4 pies

Answer:

A = 16.5

T = 33

B = 10.5

Step-by-step explanation:

T = 2A

B = A-6

T + B + A = 60

(2A) + (A-6) + A = 60

4A - 6 = 60

4A = 66

A = 16.5

T = (16.5)*2 = 33

B = 10.5

Answer:

The diameter of Pool A is  14.64  meters. So, the diameter of Pool B  is greater, and the circumference is  greater  by  0.56 meters.

Step-by-step explanation:

Identify the diameter of Pool A.

d = 2r

d = 2(24) Substitute 24 for r.

d = 48 ft

Convert from feet to meters. Use the ratio of 1 foot to 0.305 meters. Round to the nearest hundredth.

48 × 0.305 = 14.64

The diameter of Pool A is about 14.64 meters.

Use the formula to find the circumference of Pool A.

C = πd

C = π(14.64) Substitute 14.64 for d.

C ≈ 3.14(14.64) Substitute 3.14 for π.

C ≈ 45.97 Multiply.

The circumference of Pool A is about 45.97 feet.

Identify the diameter of Pool B.

d = 14.82 m

The diameter of Pool B is 14.82 meters.

Use the formula to find the circumference of Pool B.

C = πd

C = π(14.82) Substitute 14.82 for d.

C ≈ 3.14(14.82) Substitute 3.14 for π.

C ≈ 46.53 Multiply.

The circumference of Pool B is about 46.53 feet.

The circumference of Pool B is greater than the circumference of Pool A.

Find how much greater the circumference of Pool B is compared to the circumference of Pool A.

46.53 − 45.97 = 0.56

The circumference of Pool B is greater than the circumference of Pool A by about 0.56 meters.

Answer:

x = 5, y = 2.5

Step-by-step explanation:

Because the original image is scaling down 4, it means all of the values of the shape will be scaled down, or divided by 4.

20, which divided by 4, will make x equal 5.

10, which divided by 4, will make y equal 2.5

Answer:

x = 3

Step-by-step explanation:

The angle measuring 5x and the angle measuring 165° are a linear pair, so they are supplementary. Their measures add to 180°.

5x + 165 = 180

5x = 15

x = 3
