Answers

Answer 1

Answer:

                    aₙ = 6 + (n - 1)*7

a₃ = 6 + (3 - 1)*7 = 20

a₅ = 6 + (5 - 1)*7 = 34

In a pile of playing cards, there are six hearts, twelve clubs, and six diamonds. What is the probability that you will draw a heart?
1/2
1/6
1/4
1/3

Answers

Answer:

Step-by-step explanation:

1/4 because all equal 24 together

and so

12 is half so pulling a club would be 1/2

6 is a fourth so pulling a diamond or heart would be 1/4

because 6x2=12 so pulling a diamond or heart would be 50 - 50 from pulling a heart/diamond or a club

6=cards

2=diamonds and hearts

The probability of drawing a heart from the pile of 52 cards is 0.25.

The ratio of the number of favorable outcomes to the total number of outcomes of an event is defined as probability.

We know, the probability of an event = Number of favorable outcomes/Total number of outcomes.

As it is given that there are 6 hearts, 12 clubs, and 6 diamonds in a pile of playing cards.

Therefore, the total number of outcomes = 6+12+6= 24

and number of favorable outcomes = 6

Now, the probability of an event = 6/24

= 1/4

= 0.25

Therefore, the probability of drawing a heart is 0.25.

please help with surface area of cylinder

please help with surface area of cylinder

Answers

Answer:

Step-by-step explanation:

The surface area of a cylinder can be calculated using the formula:

SA = 2πr^2 + 2πrh

where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is approximately equal to 3.14.

Looking at the given diagram, we can see that the height of the cylinder is 10 cm and the radius of the base is 6 cm.

So, substituting these values into the formula:

SA = 2π(6)^2 + 2π(6)(10)

SA = 2π(36) + 2π(60)

SA = 72π + 120π

SA = 192π

Using a calculator, we can approximate this value to:

SA ≈ 602.88 cm^2

Therefore, the surface area of the cylinder is approximately 602.88 cm^2.

First we find the area of kne circle and then multiply it since we have 2 so 28x3.14 and then we fine then we find the area of the rectangle and then we add it all up to get 60.288

when x = 0,
y = ( 4 x 0) -1

A jar contains 1,000 marbles. Omar is entering a contest to guess the number of any one color of marbles in the jar. He is allowed to take four random samples of 200 marbles. The results of his samples are shown in the table.

Omar uses the information in the table and the following steps to estimate the number of blue marbles in the jar.

He considers the smallest ratio of blue marbles: 58/200
He considers the largest ratio of blue marbles: 82/200
He estimates that there are most likely between 580 and 820 blue marbles in the jar.

Is Omar's estimate reasonable? Why or why not?

A jar contains 1,000 marbles. Omar is entering a contest to guess the number of any one color of marbles

Answers

It is not because only doing the first one you need to scale it to 1000 so you would need to multiply 58 by 5 and that only gets you to 290 so automatically the estimate can not be reasonable.

Sum of 5

There are 4 outcomes that have a sum of 5 when rolling two dice:

There are 36 total possible outcomes, so the probability of rolling a 5 is ...

The side lengths of a triangle area are 5, 3, and 4. Is this a right triangle?(question and answers attatched)

Answers

Answer:

C

Step-by-step explanation:

We can use the Pythagorean Theorem to find if this really is a right triangle.

3² = 9

4² = 16

5² = 25

9 + 16 (?) 25

9 + 16 = 25

Your answer would be C.

Hope this helps. Have a nice day.

Answer:

C.)Yes because \(3^{2} + 4^{2} = 5^{2}\)

Step-by-step explanation:

The Pythagoras theorem should be applied in this question. This theorem can only be applicable if the triangle has a right angle ( 90° ) therefore it is used.

\(a^{2} + b^{2} = c^{2}\) (The Pythagoras theorem)

\(3^{2} + 4^{2} = 5^{2}\)

\(3^{2}\) = 9 and \(4^{2}\) = 16. So,

9 + 16 = 25 and \(5^{2}\) = 25

∴ The sides proves that it is a right angled triangle.

The base and height of a triangle are increased by 30% of their initial length. By what percentage does the area of the triangle increase?

Answers

Step-by-step explanation:

Area of a triangle is directly proportional to the base and height of the triangle.

Let B and H be the original base and height of the triangle respectively.

The new triangle has base 1.3B and height 1.3H

Area of original triangle : Area of new triangle

= 0.5BH : 0.5(1.3B)(1.3H)

= 0.5BH : 0.5(1.69BH)

= 1 : 1.69

Hence, the new triangle is 69% larger than the original triangle.

the answer is 69% hope it helps
