.
Answers
Answer:
Chen:15$
Phyllis: 50$
Step-by-step explanation:
Hi!
Here's what we have:
Chen's equation and Phyllis's graph.
Let's start with Chen. His equation is y=15x+15, where y is the total and x is the week. Chen's starting amount will be the amount at the zeroth week. Now, the zeroth week is when x = 0 --> y=15(0) + 15 --> y=15
So, Chen starts off with 15$.
Now, looking at the graph, Phyllis starts off at a number between 60 and 40 (we're looking at the y-intercept because that's when x=0)
The only number between 60 and 40 in the answer choices is 50.
Phyllis starts with 50$.

The mean weight for team A with 15 members is 140 pounds, the mean weight for team B with 7 members is 135 pounds, and mean weight for team C with 20 members is 160 pounds. The overall mean weight for all three teams is
Answers
Answer:
86.74 pounds
Step-by-step explanation:
Team A
The mean weight for team A with 15 members is 140 pounds
Total weight for Team A = Mean × number is members
= 15 × 140 pounds
= 2100 pounds
Team B
The mean weight for team B with 7 members is 135 pounds
Total weight for Team B = Mean × number is members
= 7 × 135 pounds
= 945 pounds
Team C
Mean weight for team C with 20 members is 160 pounds.
Total weight for Team C = Mean × number is members
= 20 × 160 pounds
= 3200 pounds
The total number of members from the 3 teams =( 15 + 7 + 20) members
= 42 members
The total weight in pounds from the 3 teams = (2100 + 945 + 3200)
= 6245 pounds
The overall mean weight for all three teams is calculated as:
6245/42 members
= 86.736111111 pounds
Approximately = 86.74 pounds

Answer:
A baseball diamond is a square with sides of 90 feet. What is the distance to the nearest tenth of a foot between home and second base?
Step-by-step explanation:
127.3 feet This problem requires the use of pythagoras theorem. Ignore the face that it's a baseball diamond. All you're concerned with is that you have a square that's 90 feet per side and you want to know what the length of the diagonal. So you have a right triangle with 2 sides of 90 feet each and you want to know the length of the hypotenuse. The formula is C^2 = A^2 + B^2 Both A and B are 90, so plugging them into the formula gives C^2 = 90^2 + 90^2 = 8100 + 8100 = 16200 So C^2 = 16200 Take the square root of both sides C = 127.2792 Round to the nearest tenth, giving C = 127.3

(2) distribute 32 as 30 + 2 and solve.
60 x 32

When there is more than one point on a vertical line that is not a function.Like in the third picture points (2,1) and (2,-1) are on the same vertical line.
P.S: it is a function if there is more than one point on a horizontal line.
Why you may ask:
x are the domain, y are the codomain. X can have multiple Y but Y can't have more than one X. To embody: think Xs as mothers and Ys as childrens , a mother can have more than one children but every children can have only one biological mother.

Clare analyzes oil prices in her economics class. She finds that the mean oil price between 1988 and 2002 is $27 per barrel with a standard deviation of $5.50 per barrel. Select the z-score for a price of $35.25 per barrel. (Select one answer)
0.67
1.5
8.25
-8.25
Answers
Answer:
Option 2: 1.5 is the correct answer.
Step-by-step explanation:
Given information is:
Mean = μ = $27
SD = σ = $5.50
A z-score simply tells us how far a selected data value from the mean is.
Z-score is denoted by z and is given by the formula:
[tex]z = \frac{x-mean}{SD}[/tex]
Let x = $35.25
Putting the values of mean and SD we get,
[tex]z = \frac{35.25-27}{5.50}\\z = \frac{8.25}{5.50}\\z =1.5[/tex]
The value of z-score for a price of $35.25 per barrel is 1.5
Hence,
Option 2: 1.5 is the correct answer.

Answers
Answer:
The formula f(t) will be:
[tex]\:f\left(t\right)=2150\left(0.962\right)^t[/tex]
Step-by-step explanation:
We know that exponential decline in Maths can be termed as a consistent reduction of an amount by percentage over a certain period of time.
It can be expressed using the formula
[tex]f\left(t\right)=\:a\:\left(1-b\right)^t[/tex]
here
f(t) represents the final amount
a represents the original amount
b represents the decay factor
t represents the amount that has passed
Now, map our problem using the same concept formula
as
2150 members are at the beginning, so
a = 2150
as the size of the population has been experiencing an annual decline of 3.8%. so
b = 3.8%= 0.038
so substituting b = 0.038 and a = 2150
[tex]P=f\left(t\right)=\:a\:\left(1-b\right)^t[/tex]
[tex]\:f\left(t\right)=2150\left(1-0.038\right)^t[/tex]
[tex]\:f\left(t\right)=2150\left(0.962\right)^t[/tex]
Therefore, the formula f(t) will be:
[tex]\:f\left(t\right)=2150\left(0.962\right)^t[/tex]

We have a ribbon that is 6/8 of an inch long. We want to cut it into 1/8 inch pieces. We can see there will be exactly 6 pieces
Note how 6*(1/8) = 6/8
Or we can think of it as "we have a ribbon that is 6 units long and we want to cut it into pieces that are 1 unit each, so we'll have 6 pieces total". Replace "unit" with "1/8 inch" and you'll have the same idea.
Answer:
6 pieces
Step-by-step explanation:
1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 6/8 = 3/4
