3) A box contains 4 yellow marbles, 2 blue marbles, and 3 red marbles. If a marble is drawn randomly from
the box, but the marble drawn is replaced. What is the probability of drawing 2 yellow marbles and 1 red
marble?
Answers
Hey buddy I am here to help!
yellow marbles = 4
blue marbles = 2
red marbles = 3
total marbles = 9
1 random marbles taken off probability left = 8/9
1 random marble taken off probability = 1/9
marble if replaced = + 1
if one marble if replaced then = 8/9 + 1/9 = 9/9 that means total marbles r 9
yellow marbles drawn off = 2
so... 4 - 2 = 2 marbles left
red marbles taken off = 1
so... 3 -1 = 2 marbles left
probability/answer = 3/9 = 1/3
Hope it helps!

Johnny Bravo bought Amazon 25 shares at $50. He sold them at $2346 a few years later. How much money did he make on this stock?
Answers
Answer:
$1096
Step-by-step explanation:
If Johnny Bravo bought Amazon 25 shares at $50, the cost price is expressed as;
Cost price of 25shares = 25 * 50
Cost price of 25shares = $1,250
If he sold them at $2346 a few years later
Profit = Selling price - Cost price
Profit made = 2346 - 1250
Profit made = $1096

Solve 270=3e^2.4K to the nearest hundredth
If you can solve this for me could you please give steps so I can understand, please and thank you so much!
Answers
Given:
The equation is:
[tex]270=3e^{2.4K}[/tex]
To find:
The solution for the given equation to the nearest hundredth.
Solution:
We have,
[tex]270=3e^{2.4K}[/tex]
Divide both sides by 3.
[tex]\dfrac{270}{3}=e^{2.4K}[/tex]
[tex]90=e^{2.4K}[/tex]
Taking ln on both sides, we get
[tex]\ln (90)=\ln e^{2.4K}[/tex]
[tex]\ln (90)=2.4K[/tex] [tex][\because \ln e^x=x][/tex]
Divide both sides by 2.4.
[tex]\dfrac{\ln (90)}{2.4}=K[/tex]
[tex]\dfrac{4.4998}{2.4}=K[/tex] [tex][\because \ln (90)\approx 4.4998][/tex]
[tex]1.874916667=K[/tex]
Round the value to the nearest hundredth (two decimal place)
[tex]K\approx 1.87[/tex]
Therefore, the value of K is 1.87.

C)
Fill in the blank with a number that would make the standard deviation smaller.
3, 10, 8, 3, 10, 1, 10,
Answers
Answer:
A) 23
B) 75
C) 6.30
Step-by-step explanation:
A) Range = highest value - least value
Range = 20
least value = 3
Thus,
20 = highest value - 3
highest value = 20 + 3
= 23
The number that would make the range of the data set 20 is 23.
B) Let the number be represented by x, so that;
15 = [tex]\frac{3 + 10 + 8 + 3 + 10 + 1 + 10 + x}{8}[/tex]
cross multiply to have
15 x 8 = 45 + x
120 - 45 = x
x = 75
The number that would make the mean of the data set 15 is 75.
C) The given data plus a number that is close to the mean would reduce the standard deviation.
mean of the data set = [tex]\frac{3+10+8+3+10+1+10}{7}[/tex]
= 6.43
The required number could be 6.30
Ms. Joseph is saving money for a trip to Zearnland over 12 weeks. She starts with 1 dollar. In the second week, she adds 2 dollars. Each week she adds 1 more dollar than she did the week before. How many weeks will she be saving money?
Answers
Answer: $78
Step-by-step explanation:
You start out with $1
$2 = second week $3 = third week $4 = fourth week $5 = fifth week $6 = sixth week $7 = seventh week $8 = eighth week $9 = ninth week $10 = tenth week $11 = eleventh week $12 = twelth week
then you add it all up = 1+2+3+4+5+6+7+8+9+10+11+12 that would equal to $78

b. the solution is 3 times as small as 3x(465x4)
c. the solution is 3 times as large as 5x(465x4)
d. the solution is 3 times as large as 5x(465+4)
Answers
Answer:
c. the solution is 3 times as large as 5x(465x4)
Step-by-step explanation:
I assume you are using the letter x as the multiplication sign.
Start with:
15 x (465 x 4)
We know that 15 = 3 x 5
Now we replace 15 with 3 x 5 in the original expression.
15 x (465 x 4) = 3 x 5 x (465 x 4)
Answer: c. the solution is 3 times as large as 5x(465x4)

set of data has a normal distribution with a mean of 56 and a standard deviation of 7. Find the percent of data within the following interval.
from 35 to 77
SOMEONE PLEASE HELP
Answers
Answer:
.99815
which is about
99.815%
Step-by-step explanation:
we are looking for 35<x<77
We need to find (what I think is called) the z score which is acheieved through what I'm pretty sure is called standardizing
What we do is subtract the mean and then divide by the standard deviation
so for 35 we have
(35-56)/7= -3.29
due to the fact that the normal distribution is symmetric this is equal to 1-p(3.29)
to find p(3.29) grab a ztable and get p(3.29)= .9995
1-.9995= .0005
For 77 we have
(77-56)/7=3
grab a ztable and find the 3= .99865
Finally subtract these two to get the final answer
.99865-.0005= .99815

Step-by-step explanation:
2x / 7 - 3 = 2
2x / 7 - 3 + 3 = 2 + 3
2x / 7 = 5
(2x /7) x 7 = 5 x 7
2x = 35
x = 35/2 or 17.5
Answer:
[tex]x = \frac{35}{2} [/tex]
Step-by-step explanation:
[tex] \frac{2x}{7} -3=2[/tex]
[tex] \frac{2x}{7} = 2 + 3[/tex]
[tex]\frac{2x}{7} = 5[/tex]
[tex]x = \frac{7}{2} \times 5[/tex]
[tex]x = \frac{35}{2} [/tex]

15 = 3w solve for w, what does w equal
Answers
Answer:
w = 5
Step-by-step explanation:
15 = 3w
Switch sides.
3w = 15
Divide both sides by 3.
w = 5
3w = 15
Divide both sides by 3
3w ÷ 3 = 15 ÷ 3

whats 38273 round off to 100

Answer:
38,300
Step-by-step explanation:
The hundredth number is the third number to the left from the right.
If we look to the number right of 2, there 7.
Since we are rounding: 5 or more...raise the score, 4 or less...let it rest.
Well 7 is greater than 5 so we round 2 up to 3

Here’s why:
We would first locate the hundreds place. The hundreds digit would be '2'.38,273
If the tens place (the digit to the right) is greater than or equal to 5, then we would round up. If the tens place is less than or equal to 4, we round down. Since the 7 is greater than or equal to 5, we would round up.⸻⸻⸻⸻

Maggie bought 45 oz of flour for her bakery. She used 17.5 oz to make a loaf of bread, and 0.71 oz for each muffin. How many muffins did Maggie make if she had 14.72 oz of flour left over?
Answers
Answer:
18 muffins
Step-by-step explanation:
Amount of flour Maggie used
Total amount of flour she bought - Amount of flour left over.
= 45oz - 14.72 oz
= 30.28 oz of flour
She used 17.5 oz to make a loaf of bread, and 0.71 oz for each muffin.
Hence,
Let the number of muffins = x
17.5 + 0.71x = 30.28
0.71x = 30.28 - 17.5
0.71x = 12.78
x = 12.78/0.71
x = 18 muffins
Therefore, Maggie made 18 muffins
