In a group of 28 students, 12 study both Art and Biology.
12 study Biology but not Art.
4 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answer:
100%
Step-by-step explanation:
Use conditional probability:
P(B | A) = P(B and A) / P(A)
P(B | A) = (12/28) / P(A)
We need to find the probability that a student studies art.
P(A or B) = P(A) + P(B) − P(A and B)
24/28 = P(A) + (12+12)/28 − 12/28
P(A) = 12/28
P(B | A) = (12/28) / (12/28)
P(B | A) = 1
What this means is that all of the students who study art also study biology.
Kaitlin has two puppies. Puppy A weighs 12 pounds and is gaining 1.5 pounds each week. Puppy B weighs 18 pounds and is gaining 0.75 pounds each week. How many weeks, x, will it take for the two puppies to weight the same amount?
Answer:
x = 36 because the LCM of 18 and 12 is 36
Tickets for a high school football game cost $2.50 each if purchased in advance. They cost $3.75 each if bought at the gate on the day of the game. For a particular game , 250 tickets were sold at the gate. If the sales totaled $1750, how many tickets were sold in advance?
250*3.75=937.5
1750-937.5=812.5
812.5/2.5=325
325 tickets were sold in advance :)
Answer:
1,500 tickets were sold in advance.
Step-by-step explanation:
$ 1,750 - 250 tickets = 1,500 tickets

Luka made an elaborate code to remember the 10 digit combination to his bicycle lock. This is the code he came up with:
F-G-E-D-A-K-B-J-C-H
Each letter stands for a different digit (0-9). Stusy the clues below to figure out what digit is represented by each letter. When two letters are written together without an operation symbol, they represent a tens digit and a ones digit.
F+F+F=D B÷H=K. H+A=CC. H+H=B. F•H=CK. D•F=KG. G+B+E=D+A+C A•H=KE J÷F=K. F/J=H/B
What is the 10-digit combination to Luke's bicycle lock?
Answer:
Anymore clues?
Step-by-step explanation:
2x - 1y = -9
y = - 5 - 5x
Answer:
x = - 7 and y = 30
Step-by-step explanation:
2x - y = -9
subtract 2x from either side
-y = -9 - 2x
divide either side by -1
y = 9 + 2x
Plug in 9 + 2x for y
9 + 2x = -5 - 5x
Add 5 to either side and subtract 2x from either side
14 = -2x
divide either side by -2
-7 = x
plug in -7 for x in one of the equations
y = -5 - ( 5 x -7 )
y = -5 - ( - 35)
y = -5 + 35
y = 30
plug in x and y
30 = -5 - ( 5 x -7)
30 = -5 - (-35)
30 = -5 + 35
30 = 30
Answer:
B. −19
Step-by-step explanation:
Multiply both sides of the equation by y , and then isolate the variable.
y−1y
=

y−1
=
10y
−1
=
9y
−19
=
y
Divide both sides by 9

Your school band needs to buy new recording equipment. The equipment will cost $3000. The band has collected $1200 in previous fundraisers. If the band sells sandwiches at $5 each, how many sandwiches will they need to sell to raise remaining funds?
Answer:
360
Step-by-step explanation:
Total amount needed = $3000
Amount available = $1200
Remaining amount = Total amount needed - Amount available
= $3000 - $1200
= $1800
If the band sells sandwiches at $5 each, how many sandwiches will they need to sell to raise remaining funds
Number of sandwiches to sell = Amount remaining / price of sandwiches
= $1800 / $5
= 360
Therefore, the band will need to sell 360 sandwiches to raise remaining funds
Can someone figure this out??
Answer:
x = 6 2/3
Step-by-step explanation:
We can use ratios to solve
x/4 = 15/9
Using cross products
9x = 4*15
9x = 60
Divide each side by 9
x = 60/9
x = 20/3
x = 6 2/3

In a normal distribution, what is the probability that a data value will fall above the
data value associated with a z-score of 0.15?
A 55.96%
B 53.98%
C 44.04%
D 46.02%
Answer: C 44.04%
Step-by-step explanation:
in a normal distribution,
P(Z>z)= 1-P(Z<z) (*)
Here , we need to find : P(Z>0.15)
By using (*) , P(Z>0.15)=1- P(Z<0.15)
= 1- 0.5596 [By p-value table]
= 0.4404
= 44.04% [multiply 100 to convert into percent]
∴ the probability that a data value will fall above the data value associated with a z-score of 0.15 = 44.0%
hence, correct option : C 44.04%
Jon and Lexi are playing a marble game. According to their rules, 4 points are awarded for each red marble collected and 3 points are awarded for each blue marble collected. Which expression represents Jon's total score if he has r red marbles and b blue marbles?
4r − 3b
2r − 3b
4r + 3b
7rb
Answer:
i believe the answer is 4r - 3b
Answer:
4r+3b
Step-by-step explanation:
4 red awarded = 4r
3 blue awarded = 3b
Score = 4r + 3b

how does cheese spoil?
Answer:
Microbiological spoilage of cheese is one of the important reasons that render the nutritious and tasty cheese not only inedible but also a potential source of infection. The spoilage may be due to bacteria or fungi. The defect due to contamination may arise from the surface of the cheese showing visual and organoleptic changes or it may be hidden internally.
Answer:
Cheese: It smells like sour milk.
If you spot mold on hard cheese, it's generally safe to cut off the moldy part and eat the rest, since the spores likely will not have spread throughout the cheese. Another sign that cheese has gone bad is a smell or taste of spoiled, sour milk.

Answer:
The rate of change or the slope is 4/1 or just 4.
Step-by-step explanation:
To find the rate of change, you have to figure out the distance between the y values and x values.
The distance from 6 to 10 for number 1 is 4, and it continues with the same pattern of 4!
The distance in the x values for number one is just 1! It stays as one for the entire table.
Now we put our information in a fraction.
Y is always over X. Y/X
4/1 or just 4.
Lastly, I'm a bit confused on what exactly it means by Start value but I'm sure you can email your teacher about that.
Hope this helps! :)
John was 40" tall in 2008 and 46" tall in 2010. Dave was 53" tall in 2003 and 70" tall in 2007. Who is growing at
a faster rate? If each person keeps growing at the same rate, how tall can we expect each to be in 2011? Is this
a reasonable expectation?
Answer:
John is growing at a faster rate.
Step-by-step explanation:
John grew 6 inches in 2 years, while Dave grew 7 inches in 4 years. We can expect John to grow another 3 inches by 2011, making John 49 inches tall in 2011. We can expect Dave to grow about another 7 inches by 2011, since another 4 years has passed. This seems reasonable enough...
