Answer: C. 30:1

Step-by-step explanation:

A ratio of x:y is created by taking the number of x and the number of y, plugging them in, and reducing if necessary. In this problem, x is orange trees and y is cherry trees. There are 30 orange trees and only 1 cherry tree, so the ratio is 30:1. It cannot be reduced.

Answer:

25% decrease

Step-by-step explanation:

Percentage Decrease = [(Start Value - Final Value) / |Start Value|]×100

80 - 60 = 20

20 / 80 = 0.25

0.25(100)= 25%

Answer:

There are many ways we can write [tex]5^{11}[/tex] one of them being that we just write 11 fives being multiplied against each other like the following:

[tex]5*5*5*5*5*5*5*5*5*5*5[/tex]

This can seem very repetitive which is why powers are a lot more helpful.  We can also rewrite [tex]5^{11}[/tex] using the power in the bottom of a fraction.  The way that we do this is put [tex]5^{-11}[/tex] on the bottom which can then be flipped to the top with a positive power and will be the same.

[tex]\frac{1}{5^{-11}}[/tex]

The final way that we can rewrite [tex]5^{11}[/tex] is by using several different powers.  We can do [tex]5^6*5^5[/tex] which will equal the same thing as [tex]5^{11}[/tex] because the base is the same and what we basically do is just add up the powers together to get back to 11.

[tex]5^6*5^5[/tex]

[tex]∠BAD≈65.22°[/tex]

Note:

The following formula is tan formula:

[tex]tan(\theta)=\dfrac{opposite}{adjacent}[/tex]

1) Finding the tan of ∠BAC

[tex]tan(\theta)=\dfrac{4}{5}[/tex]

[tex]\theta=tan^-1(\dfrac{4}{5})[/tex]

2) Finding the tan of ∠CAD

[tex]tan(\theta)=\dfrac{3}{6}[/tex]

[tex]\theta=tan^-1(\dfrac{3}{6})[/tex]

3) Add the value of ∠BAC to the value of ∠CAD

[tex]tan^-1(\dfrac{4}{5})+tan^-1(\dfrac{3}{6})≈65.22°[/tex]

4) The sum of interior angles in quadrilateral is 360°

Then

[tex]tan(∠BAC)+tan(∠ACB)+tan(∠CAD)+tan(∠ACD)=360°[/tex]

[tex]tan^-1(\dfrac{4}{5})+tan^-1(\dfrac{5}{4})+tan^-1(\dfrac{3}{6})+tan^-1(\dfrac{6}{3})=180°[/tex]

[tex]180°+∠CDA+∠CBA=^?360[/tex]

[tex]180°+90°+90°=^?360°[/tex]

[tex]360°=360°[/tex]

If I am correct, it would be 6x + 6x + 3x - 5 + 3x - 5.  I am almost positive this is what they are asking for.  If I am incorrect, I will answer three questions for free, on any topic of your choosing.  In advance, sorry if I'm incorrect.

The correct options are:

The probability you select a purple marble is 3/10

P(Red) + P(Yellow) + P(Purple) = 1

The probability you select a green marble is 0.

Probability calculates the chance that an event would happen. If it is certain that the event would not happen, it would have a value of 0. If it is certain that the event would happen, it would have a value of 1.

Probability of picking a red marble = total number of red marbles / total number of marbles

= 4/10

Probability of picking a purple marble =  total number of purple marbles / total number of marbles

3/10

P(Red) + P(Yellow) + P(Purple) = 4/10 + 3/10 + 3/10 = 1

Here is the complete question:

A bag contains four red marbles, three yellow marbles, and three purple marbles. You will randomly select one marble from the bag.

Which statements are true regarding the scenario? Check all that apply.

The probability you select a red marble is 3/10

The probability you select a purple marble is 3/10

P(Red) + P(Yellow) + P(Purple) = 1

The probability you select a green marble is 0.

The probability you select a yellow marble is 3.

Kate can see across the horizon by 3.33 times further than Paul.

The assumed shape of the horizon shows that it forms a cone shape. The volume of the cone can be used to determine how far they can see.

The volume of the cone [tex]\mathbf{ V=\pi r \dfrac{h }{3}}[/tex]

For Kate:

[tex]\mathbf{ V=\pi r \dfrac{h }{3}}[/tex]

[tex]\mathbf{ V=\pi \times (6371000)^2 \times \dfrac{50 }{3}}[/tex]

V = 2.12526863 × 10¹⁵ m³

For Paul

[tex]\mathbf{ V=\pi r \dfrac{h }{3}}[/tex]

[tex]\mathbf{ V=\pi \times (6371000)^2 \times \dfrac{15 }{3}}[/tex]

V = 6.3758059 × 10¹⁴ m³

To determine how much further can kate see across the horizon than Paul, we have:

= Volume of Kate/Volume of Paul

= 2.12526863 × 10¹⁵ m³/6.3758059 × 10¹⁴ m³

= 3.33 times further.

Answer:

x = -3/2

Step-by-step explanation:

x + 3 + d  = 2x + 1              First term plus common difference = 2nd term

x -2 = d

x + 3 + 2d = 5x+2              First term + 2 d = third term    re-arrange:

4x-1 = 2d                            sub in the definition of d from above

4x -1 = 2 (x-2)

4x-1 = 2x-4

2x = -3

x = -3/2

If x+3, 2x+1, and 5x+2 are consecutive terms of an arithmetic sequence then x is -3/2.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The sequence in which consecutive terms will have common difference is called as Arithmetic sequence.

x+3, 2x+1, and 5x+2

The common difference between first term and second term

d=2x+1-x-3

d=x-2

The common difference between second term and third term

5x+2-2x-1=d

3x+1=d

Now plug in d value

3x+1=x-2

Subtract x from both sides

3x-x=-3

2x=-3

Divide both sides by 2

x=-3/2

Hence, if x+3, 2x+1, and 5x+2 are consecutive terms of an arithmetic sequence then x is -3/2.

Answer:

$288

Step-by-step explanation:

We first need to find what 0.8% of 300 makes and to do that we multiply 300 with 0.8 and divide that by 100

300*(0.8)/100 = 2.4 this is the monthly interest

Now we need to find how much it'd be after 10 years

There are 10*12 = 120 months in 10 years

120*(2.4) = 288 is the interest Bob will earn after 10 years

0.3456 = 34.56%

Step-by-step explanation:

Binomial distribution

[tex]\displaystyle P(X=x)=\binom{n}{x} \cdot p^x \cdot (1-p)^{n-x}[/tex]

where:

Given:

Substitute the given values into the formula:

[tex]\begin{aligned}\implies \displaystyle P(X=3) & =\binom{5}{3} \cdot 0.6^3 \cdot (1-0.6)^{5-3}\\ & = \dfrac{5!}{3!(5-3)!}\cdot 0.6^3 \cdot 0.4^2\\ & = 10 \cdot 0.216 \cdot 0.16\\ & =0.3456\end{aligned}[/tex]

Therefore, the probability of exactly 3 successes is 0.3456 = 34.56%

The answer would be [tex]\frac{1}{2}[/tex].

Answer:

  51/100

Step-by-step explanation:

The probability is the ratio of the number of outcomes of interest to the total number of possible outcomes.

__

There is one number 5. There are 50 numbers in the range 1–100 that are greater than 50. So, the total number of outcomes of interest is 1+50 = 51.

The possible outcomes are any of the numbers 1–100, so there are 100 of them.

The probability of interest is ...

  P(n=5||n>50) = 51/100

Answer:

(a) C = $9250

(b) n = 21 tons

Step-by-step explanation:

(a)   11 tons being transported, so n = 11.

                ∴ C = 250 (11) + 650

                        C = $9250

(b)   C = $11,750

       ∴ 11750 = 250n + 6500

                250n = 5250

                   n = 21 tons
