A store purchases baseball hats from two different manufacturers in 3 different colors, summarized
below. One hat is chosen at random. Give your answer as a decimal out to at least 4 places.
Black Blue Red Total
Manufacturer A 23 21 29 73
Manufacturer B 27 17 10 54
Total 50 38 39 127
х
a) Find the probability that the hat was was Black or was from Manufacturer A. 0.3150
O 0.78740157480315
b) Find P(Red).
c) Find P(Manufacturer B and Red),
d) Find P(Manufacturer B or Red).
Answers
Answer:
See below
Step-by-step explanation:
a)
P(A or Black) = (73 + 27)/127 = 100/127 = 0.7874015748
b)
P(Red) = red/total = 39/127 = 0.30708661417
c)
P(Manufacturer B and Red) = (B and red)/total = 10/ 127 = 0.0787401575
d)
P(Manufacturer B or Red) = (B or red)/total = (54 + 29)/127 = 0.65354330708

The equation LaTeX: p=5000\cdot2^tp = 5000 ⋅ 2 t represents the population of an invasive fish species in a large lake, years since 2005, when the fish population in the lake was first surveyed.
What was the population in 2005?
Answers
Answer:
10000 fish species
Step-by-step explanation:
Given
[tex]p=5000\cdot2^t[/tex]
Required
Find the population in 2005
2005 is the first year
So: [tex]t = 1[/tex]
Substitute 1 for t in [tex]p=5000\cdot2^t[/tex]
[tex]p=5000\cdot2^t[/tex]
[tex]p = 5000 * 2^1[/tex]
[tex]p = 5000 * 2[/tex]

What is the commutative property? (Please don't copy and paste from go.ogle I need a good explanation)
Answers
Answer:
it basically means that the order in how you multiply doesnt matter. so wether u type 5 x 4 or 4 x 5 in ur calculator, you'll get the same answer either way. this works for when you want to multiply and divide, but not when you wanna subtract or divide.
Step-by-step explanation:
its basically a property that says that if you wanna swap the numbers/variables that are on one side of this specific type of equation (multiplication and addition), you can!
Answer:
yooo
Step-by-step explanation:
the communitive property is when you have the same number or same equation but just reverse it. For example, (5x+67) with the communitive property could be (67+5x). Its just the equation you are given but reversed and since they are the same numbers, you will get the same answer either way you do the problem, hope this helps you lol.

.Jessica is making metal sculptures to sell. A metal sculpture costs $24 to make and Jessica sells it to
a retailer for a profit of 175%. If the retailer then marks up the sculpture by another 120%, how
much will it cost someone to buy a sculpture in the shop?
Answers
Answer:
$50.40
Step-by-step explanation
The sculpture cost $24 to make so for her to make a 175% profit think of it as a decimal which is 1.75. So you do 24*1.75=$42. Then retailer marks up an additional 120% so then it'll be 42*1.20= 50.4

Answers
Given the table of values that represents a linear function, the value of y when x = 4 is: 5.
Recall:
Equation of a linear function can be modelled as y = mx + b.m = slope; b = y-intercept.slope (m) = change in y / change in xy-intercept (b) is the value of y at x = 0.Find the slope of the linear function, using two pairs of values, (-4, 3) and (0, 4):
Slope (m) = (4 - 3)/(0 - (-4)) = 1/4
y-intercept (b) = 4 (from the table, when x = 0, y = 4).
Write the equation that models the function by substituting m = 1/4 and b = 4 into y = mx + b:
y = 1/4x + 4
Thus, to determine the value of y when x = 4, substitute x = 4 into y = 1/4x + 4:
y = 1/4(4) + 4
y = 1 + 4
y = 5.
Therefore, given the table of values that represents a linear function, the value of y when x = 4 is: 5.

Victor baked 30 chocolate chip cookies, 18 peanut butter cookies, and 24 sugar cookies. He wants to split them into equal and identical bags to sell at the bake sale. What is the greatest number of bags of cookies Victor can make?
Answers
Answer:
6
Step-by-step explanation:
The greatest common factor (GCF) of 18, 24, and 30 is 6. :)
Victor can make at most 6 bags with equal numbers of each type of cookie.
_____
18 = 6×3
24 = 6×4
30 = 6×5
One way to look for the GCF is to consider the differences between the numbers. The smallest difference between any pair is 6, which also divides all of the numbers evenly. Hence 6 is the GCF.

Answers
Answer:
f(10)=290
Step-by-step explanation:
Function Evaluation
Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.
We are given the function:
[tex]f(x)=3x^2-x[/tex]
It's required to find f(10). We replace the x for 10:
[tex]f(10)=3*10^2-10[/tex]
Operating:
[tex]f(10)=3*100-10[/tex]
[tex]f(10)=300-10[/tex]
[tex]f(10)=290[/tex]
Thus, f(10)=290

Given:
Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.
To find:
The percentage increase of amount of pears picked by Kim.
Solution:
We know that,
[tex]\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
[tex]\%\text{ increase}=\dfrac{287-250}{250}\times 100[/tex]

Samuel is buying a pair of boots with an original price of $80.
• Store A is offering a 25% discount off the original price of all boots.
• Store B is offering a $10 discount off the original price of all boots.
Based on this information, which statement is true?
Answers
The best deal was given by store A. Because the price at store A is less than store B.
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Samuel is purchasing a couple of boots with a unique cost of $80.
Store A is offering a 25% markdown off the first cost, everything being equal. Then the price of the boot will be given as,
⇒ (1 - 0.25) x $80
⇒ 0.75 x $80
⇒ $60
Store B is offering a $10 markdown off the first cost, all things considered. Then the price of the boot will be given as,
⇒ $80 - $10
⇒ $70
Based on this information, the best deal given by store A.
