Answer:

Green marbles are probably = 62.5.

Step-by-step explanation:

Since Jan completes 60 trials and pulled green 15 times, the probability of any marble being green can be calculated as:

= 15/60

= 0.25

With 250 marbles in the bag, using the probability value of green marbles calculated above, the number of green marbles can be estimated as:

= 0.25 of 250

= 62.5

This shows that since there is a 25% probability of obtaining a green marble from 60 trials of pulling colored marbles out of the bag containing 250 marbles, then the total number of green marbles will be equal to 62 or 63.

This is a linear function because there is a common difference of 4
⇒ 2nd answer
Step-by-step explanation:
- In the linear function there is a common difference between each two
consecutive data
- In the exponential function there is a common ratio between each two
consecutive data
- Lats check the data in the data in the table
(x) === 1 ⇒ 2 ⇒ 3
f(x) === 4 ⇒ 8 ⇒ 12
∵ x has consecutive numbers 1 , 2 , 3
∵ 8 - 4 = 4
∵ 12 - 8 = 4
∴ f(x) has a common difference 4
∵ 8 ÷ 4 = 2
∵ 12 ÷ 8 = 1.5
∴ f(x) has no common ratio
∴ The table represents a linear function with common difference 4
This is a linear function because there is a common difference of 4

What is three decimals that have a sum of 10.806
White raven [17]

Answer:

  10 + 0.8 + 0.006 = 10.806

Step-by-step explanation:

Pick any two decimal numbers. The third one will be the difference between 10.806 and the sum of the two numbers you picked.

For example, choose 938.2 and 3.0055. Their sum is 941.2055. Then the third number that will make the sum be 10.806 is ...

  10.806 -941.2055 = -930.3995

So, your three numbers could be ...

  {938.2, 3.0055, -930.3995}

Greg has $2,571.68 in his bank account and makes automatic monthly rental payments of $321.46 for a car loan. If he stops making
Anestetic [448]

Answer:

8 months

Step-by-step explanation:

Given that:

Amount of money present in the bank account = $2,571.68

Automatic monthly rental payments for car loan = $321.46

Any deposits in the bank account are stopped.

To find:

The number of months taken so that the automatic payments make the value of the account as zero?

Solution:

Let the number of months taken to make the value of the account zero = m months

To find the value of m, we need to divide the total amount initially present in bank account with the monthly rental payment amount.

Therefore, the equation to find the value of m, can be written as:

m = \dfrac{2571.68}{321.46}

On solving the above equation, we get the value as following:

\bold{m=8} months

Chelsea is graphing the function f(x) = 20()x. She begins by plotting the initial value. Which graph represents her first step?
Soloha48 [4]

we have the function

f(x)=20(\frac{1}{4})^{x}

we know that

In the equation of the exponential function of the form

f(x)=a(b)^{x}

a is the initial value

b is the base

x is the exponent

The initial value is the value of the function when the value of x is equal to zero

in this problem

for x=0

f(0)=20(\frac{1}{4})^{0}

f(0)=20(1)=20

the initial value is the point (0,20)

therefore

the answer in the attached figure

A carnival game allows a group of players to each draw and keep a marble from a bag. The bag contains 5 gold marbles, 25 silver
laila [671]
1. What’s the probablity of a second person winning the small prize?
There are now 99 total marbles, and 24 silver marbles. So, 24/99 is 0.24 probability.
2. Which player is most likely to win a big prize?
Since each player draws a silver marble (aka a small prize) there are less small prize marbles in the bag after each turn. So, the first person would have a 5% chance (or 0.05)of winning the big prize gold marble, but the last person would have a slightly bigger chance (5.15% or 0.0515) of winning a big prize.
3. How could the game be made fair for each player?
Well it’s quite simple, just have each player return their marble and the number of marbles would be kept constant, giving everyone an equal chance. Or you could have them all play at the same time, either way.
