The following tree diagram shows the possible outcomes for the experiment

What is the probability of getting exactly 2 tails?

Enter your answer as a reduced fraction, like this: 3/14

Answer:

Step-by-step explanation:

Since the dilation is centered at the origin, we can multiply each of the coordinates by the scale factor. This gives us that D'(36,0).

Answer:

$43 million

Step-by-step explanation:

15.4 million = 0.36 (T)

15,400,000 / 0.36 = T

42,777,777.78 = T

$42.8 million ≈ $43 million (rounded)

The final answer rounded to the nearest million is $43 million. This makes sense since $15.4 was only 36% of this total. Checking our math, 36% of $43 million is $15.4 million!

Hope this helps :)

[tex]\\ \rm\rightarrowtail \dfrac{3}{10}ft^3[/tex]

Answer:

145

Step-by-step explanation:

angle 2 = angle 3

=>          angle 3 = 35

now, we have

=>         35+angle 5 = 180

=>         angle 5 = 180 - 35

=>         angle 5  = 145

Answer:

145°

Step-by-step explanation:

line m || line (Given)

[tex]m\angle 2 = 35\degree ......(1)[/tex] (Given)

[tex]m\angle 3 = m\angle 2 ......(2)[/tex] (vertical angles)

From equations (1) and (2)

[tex]\implies m\angle 3 = 35\degree[/tex]

[tex]m\angle 3 +m\angle 5 = 180\degree[/tex] (interior angles on the same side of transversal)

[tex] \implies 35\degree +m\angle 5 = 180\degree[/tex]

[tex] \implies m\angle 5 = 180\degree-35\degree[/tex]

[tex] \implies m\angle 5 = 145\degree[/tex]

We're given:

Let a represent the number of children who swam.

Let b represent the number of adults who swam.

Because we've set two variables, we need two equations to be able to find the answers.

One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.

Number of people:

[tex]a+b=478[/tex]

Price:

[tex]1.75a+2.25b=975[/tex]

We can solve this question using substitution, where we plug one equation into the other.

Isolate a in the first equation:

[tex]a+b=478\\a=478-b[/tex]

Plug the first equation into the second equation by replacing a:

[tex]1.75a+2.25b=975\\1.75(478-b)+2.25b=975[/tex]

Solve for b:

[tex]1.75(478-b)+2.25b=975[/tex]

⇒ Open up the parentheses:

[tex]836.5-1.75b+2.25b=975\\836.5-0.5b=975[/tex]

⇒ Subtract 836.5 from both sides to isolate b:

[tex]-0.5b=138.5[/tex]

⇒ Divide both sides by -0.5:

[tex]b=277[/tex]

Solve for a:

[tex]a+b=478[/tex]

⇒ Replace b with 277:

[tex]a+277=478\\a=201[/tex]

There were 201 children and 277 children at the pool that day.

Step-by-step explanation:

If n is a perfect square, then the last digits of the prefect square must be 3 or 7  because n ends in 9.

Since n is 4 digits the number can only land between 33 and 97.

(33, 37, 43, 47, 53, 57, 63, 67, 73, 77, 83, 87, 93, 97)

1/4 of cookies

Cost of one cookies =2.95

Total cost

Answer:

$41.3

Step-by-step explanation:

Each cookie costs,

→ a = $2.95

Lemon cookies (1/4) of 56 cookies is,

→ b = 1/4 × 56

→ b = 56/4

→ [ b = 14 lemon cookies ]

The money made if she sell the lemon cookies alone will be,

→ a × b

→ 2.95 × 14

→ $41.3

Hence, the money made is $41.3.

Answer:

C. $5 for 40 ounces

Step-by-step explanation:

First, we need to find the unit rate for each deal.

To do this, we divide the price of the cereal box by the unit (ounces):

1. $3.20 for 20 ounces

3.20/20 = $0.16 for each ounce

2. $4.50 for 25 ounces

4.50/25 = 0.18 for each ounce

3. $5 for 40 ounces

5/40 = 0.13 for each ounce

4. $6.50 for 20 ounces

6.50/20 = 0.33 for each ounce

As you can see, the third one is the best deal, as it is the least expensive.

Hope this helps!

Answer:

0

Step-by-step explanation:

So,0= the lengths of springs from the original pogo stick and the toddler's pogo stick are equal.

Hence, the values for different conditions were calculated with the help of trigonometric functions.

Part A

θ=kπ

Where k is an integer k=0,1,2..

Part B

θ=[tex]k\frac{\pi }{2}[/tex]

Where k is an integer k=0,1,2..

Part C

θ=kπ

Where k is an integer k=0,1,2..

The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths

Part A

Given that,

f(x)=2sinθ+[tex]\sqrt{2}[/tex]

Non compressed length = [tex]\sqrt{2}[/tex]

Then

2sinθ+[tex]\sqrt{2}[/tex]=[tex]\sqrt{2}[/tex]

2sinθ=0

sinθ=0

Therefore θ is the integer multiple of π

θ=kπ

Where k is an integer k=0,1,2..

Part B

Here angle is doubled

Then,

2sin2θ+[tex]\sqrt{2}[/tex]=[tex]\sqrt{2}[/tex]

2sin2θ=0

sin2θ=0

Here θ will be the integer multiple of [tex]\frac{\pi }{2}[/tex]

θ=[tex]k\frac{\pi }{2}[/tex]

Where k is an integer k=0,1,2..

Part C

g(x)=1-[tex]cos^{2}[/tex]θ+[tex]\sqrt{2}[/tex]

Here

f(x)=g(x)

2sinθ+[tex]\sqrt{2}[/tex]=1-[tex]cos^{2}[/tex]θ+[tex]\sqrt{2}[/tex]

2sinθ=1-[tex]cos^{2}[/tex]θ

we know that [tex]1-cos^{2}[/tex]θ=[tex]sin^{2}[/tex]θ

2sinθ=[tex]sin^{2}[/tex]θ

sinθ=0

Therefore θ is the integer multiple of π

θ=kπ

Where k is an integer k=0,1,2..

Hence, we have solved that

Part A

θ=kπ

Where k is an integer k=0,1,2..

Part B

θ=[tex]k\frac{\pi }{2}[/tex]

Where k is an integer k=0,1,2..

Part C

θ=kπ

Where k is an integer k=0,1,2..

Step-by-step explanation:

The number of ways of combining different growth factors to form a level is 80.

The act of organizing all the components of a set into some sequence or order is known as permutation. Permuting, in other words, is the act of reordering the components of a set that has previously been sorted.

A permutation is the selection of r items from a collection of n items without replacement, with the order of the items being significant.

nPr = (n!) / (n-r)!

The combination is a method of picking elements from a collection in which the order of selection is irrelevant (unlike permutations).

A combination is a selection of r items from a collection of n items with no replacements and no regard for order.

nCr = (n!)/{(r!)((n-r)!)}

We are given that Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.

Growth factor Levels

Lighting: Low, Medium, High, Very high.

Age: 1 month, 2 months, 3 months, 4 months, 5 months.

Temperature: 20°, 22°, 24°, 26°.

We are asked to find the number of ways in which she can combine different levels to form one level.

We first check the number of combinations for each factor and then multiply them all to get the total number of ways possible.

Lighting: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 = 4).

Age: 5 (∵ All the 5 levels are possible, so the combinations are 5P1 = 5).

Temperature: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 =4).

∴ Total number of ways of combining different growth factors to form a level = 4*5*4 = 80

∴ The number of ways of combining different growth factors to form a level is 80.
