1. A bag has 16 marbles in it: 6 red, 4 blue, 3 yellow, and 3 green. A marble is drawn and put back, and then another marble is drawn. What is the probability that a blue marble was drawn followed by a yellow marble?
2. A bag has 16 marbles in it: 6 red, 4 blue, 3 yellow, and 3 green. A marble is drawn and not put back, and then another marble is drawn. What is the probability that a blue marble was drawn followed by a yellow marble?
Thank you.
Answer:
1. 0.0469 (4.d.p)
2. 0.05
Step-by-step explanation:
1. First we'll find the probability of drawing a blue marble.
P = (No. favourable events)/(Total events)
In this case it's:
P = (No. blue marbles)/(Total Marbles)
Therefore P(Blue) = 4/16 = 0.25
Now we find the probability of drawing a yellow marble:
The total number will be the same because the blue marble will have been put back.
P(Yellow) = 3/16 = 0.1875
Now, since we are calculating the probability of both happening we multiply together the two individual probabilities to get the combined probability of both:
0.25 x 0.1875 = 0.0469 (4.d.p)
2. The probability of drawing a blue marble is still the same so we can keep that: P(Blue) = 0.25
But this time, the marble is not replaced. This means that the total number of marbles has changed when drawing the yellow marble:
P(Yellow) = 3/15 = 0.2
Now we multiply them together again to find the combined probability of both happening:
0.25 x 0.2 = 0.05
Hope this helped!
Winnie's bedroom has an area of 120 square feet. The width of the room is 5/6 the length of the room. What are the dimensions of Winnie's bedroom?
Answer:
x----------> the length of the room
y----------> the width of the room
we know that
x*y=120---------> equation 1
y=(5/6)x--------> equation 2
substitute 2 in 1
x*[(5/6)x]=120------> (5/6)x²=120-----> x²=120*6/5-----> x²=144
x=12 ft
y=(5/6)*12-----> y=10 ft
the answer is
the dimensions of Winnie's bedroom are
the length of the room is 12 ft
the width of the room is 10 ft

A traffic yield sign is in the shape of an equilateral triangle. If each side is 36 inches,
what is the height of the sign to the nearest tenth of an inch?
Answer:
31.2 inches
Step-by-step explanation:
Draw a line representing the height of the triangle, and divide it into 2 triangles.
Apply Pythagoras Theorem on one of the smaller triangles first.
[tex]h = \sqrt{ {36}^{2} - {(36 \div 2)}^{2} } \\ h = \sqrt{ {36}^{2} - {18}^{2} } \\ h = \sqrt{972} \\ h = 31.17691...[/tex]
h = 31.2 inches (rounded to the nearest tenth)
Find the value of two numbers if their sum is 19 and and their difference is 5
Answer:
7 and 12
Step-by-step explanation:
x - y = 5
y = (5+x)
x+ (5+x) = 19
2x +5 = 19
2x = 14
x = 7
19-7 = 12
12 +7 = 19
12-7 = 5

Last year, Nicholas started babysitting to earn extra spending money. Over the summer, he tracked how much money he earned at each babysitting jobThis box plot shows the results What percent of the time did Nicholas earn $25 or less?
Answer:
25%
Step-by-step explanation:
The 5 values of the given box plot are;
The minimum value = 20
The first quartile, the 25th percentile point, Q₁ = 25
The median or second quartile, the 50th percentile point, Q₂ = 30
The third quartile, the 75th percentile point, Q₃ = 40
The maximum value = 55
The range = The maximum value - The minimum value
∴ The range = 55 - 20 = 35
We note that Nicholas earned $25 or less from the minimum value up to first quartile, Q₁, which is the 25th percentile point, where we have 25 percent of the data points
Therefore, the percent of the time Nicholas earned $25 or less is 25 percent of the time.

A local company had revenues of $2,800 last year. They spent 1/4 of their revenues on marketing and 1/7 of the remaining money on upgrading their facilities. How much money did they have left after marketing and upgrading the facilities? Group of answer choices
Answer:
$1,800
Step-by-step explanation:
Given
Total revenue last year = $2,800
If they spent 1/4 of their revenues on marketing;
Amount spent on marketing = 1/4 * 2800
Amount spent on marketing = $700
Remaining money = 2800 - 700
Remaining money = $2100
If 1/7 of the remaining money is spent on upgrading their facilities, then;
Amount spent on upgrading facilities = 1/7 * 2100
Amount spent on upgrading facilities = $300
Total amount spent on marketing and facilities = $700 + $300
Total amount spent on marketing and facilities = $1000
Amount left = $2,800 - $1,000
Amount left = $1,800

We are going to use trigonometry to solve for the wanted angle
Remember these are the trigonometric functions
( Remember SOH CAH TOA )
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse (CAH)
Tangent = Opposite over Adjacent (TOA)
For angle Ф
we are given its adjacent side length (6) and the hypotenuse (9)
Adjacent and hypotenuse corresponds with the trig function Cosine
So we will use cosine to solve for the missing angle
( let x = missing angle )
( remember cosine = adjacent over hypotenuse )
[tex]cosX=\frac{6}{9} \\\frac{6}{9} =.66\\cos(x)=.66[/tex]
now we want to get rid of the "cos" on the x
To do so we take the inverse of cos ( arc cos ^-!1 ) and apply it to each side
so...
[tex]arcos(cos(x))=x\\arccos(.66)=48.1[/tex]
we're left with x = 48.1

At the shop , there were 4 1/10 kg apples and 6 3/4 kg of oranges . If cumtomers bought 7 3/5 kg of apples and oranges , how many kg of apples and oranges were left
Answer:
3 1/4
Step-by-step explanation:
total kg of apples and oranges in the store =
[tex]4\frac{1}{10} + 6\frac{3}{4}[/tex]
[tex]10\frac{4+30}{40}[/tex]
[tex]10\frac{34}{40}[/tex]
kg left after the sales
[tex]10\frac{34}{40} - 7\frac{3}{5}[/tex]
[tex]3\frac{34 - 24}{40}[/tex] = [tex]3\frac{10}{40}[/tex]

What type of seismic waves can travel through the center of the Earth and be picked up by a seismograph on the other side of the world?
Answer: primary waves
Step-by-step explanation: pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name "Primary". These waves can travel through any type of material, including fluids, and can travel nearly 1.7 times faster than the S-waves.

Which of the following expressions is not equal to 64?
A. 2^4 . 2^-3 .2^4 .2
B. 2^2 .2^8 .2^-4 .2^0
C.2^0 .2 . 2^2 .2^3
D. 2^6 . 2^-3 . 2^4 . 2
Answer:
A. 2^4 . 2^-3 . 2^4 . 2
Step-by-step explanation:
Option A,
2^4 . 2^-3 . 2^4 . 2
= 2^4 . 2^-3 . 2^4 . 2^1
= 2^( 4 + 4 + 1 - 3 )
= 2^( 9 - 3 )
= 2^6
= 64
So, Option A is the correct answer.
