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
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.

Find a formula for P = f(t), the size of the population that begins in year t=0 with 2140 members and decreases at a 3.8% annual rate. Assume
that time is measured in years
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]

Exercises 13-15
Answer:
13. The measure of a is 35°
14. The measure of b is 74°
15. The measure of c is 66°
Step-by-step explanation:
In the given figure
13.
∵ The sum of the measures of the interior angles of a triangle is 180°
∴ 33° + 112° + a = 180°
→ Add the like terms in the left side
∴ 145° + a = 180
→ Subtract 145° from both sides
∵ 145° - 145° + a = 180° - 145°
∴ a = 35°
14.
∵ a, 71° and b formed a straight line
∵ The sum of the measures of the linear angles is 180°
∴ a + 71° + b = 180°
→ Substitute the value of a
∴ 35° + 71° + b = 180°
→ Add the like terms in the left side
∴ 106° + b = 180°
→ Subtract 106° from both sides
∵ 106° - 106° + b = 180° - 106°
∴ b = 74°
15.
∵ The sum of the measures of the interior angles of a triangle is 180°
∴ 43° + 71° + c = 180°
→ Add the like terms in the left side
∴ 114° + c = 180°
→ Subtract 114° from both sides
∵ 114° - 114° + c = 180° - 114°
∴ c = 66°

Point M is the midpoint of AB. If the coordinates of point Mare (2, 8) and the coordinates
of A are (10, 12), what are the coordinates of B?
Answer:
(-6,4)
Step-by-step explanation:
add the x coordinates of point A and B(take x coordinate of B as X),then divide the sum of 2 and equal it to 2 which is the x coordinate of the midpoint.
then repeat the same procedure for the y coordinates ,take the sum of y corrdinates divide by 2 and equal to 8.
then u can obtain the coordinates of B.

Answer:
(1) 820
(2) 1920
Step-by-step explanation:
(1) solving 20 x 41, using associative property.
20 * 41 = (2 x 10) x 41 = 2 x (10 x 41)
= 20 x 41 = 2 x 410
= 820 = 820
(2) distribute 32 as 30 + 2 and solve.
60 x 32
= 60 x (30 + 2) = 60(30) + 60(2)
= 1800 + 120
= 1920

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
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

The points on the graphs represent relations. Classify these relations according to whether or not they are functions.
Answer:
1 and 2 is a function.But the third one isn't.
explanation:
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.

A room is 12m 15m long and 8m 91 cm broad .The floor of the room is tobe paved with squared tiles find the lenght of the largest tile that can be used
Answer:
81 cm
Step-by-step explanation:
Length of a room = 12m 15cm
Width of a room = 8 m 91 cm
12 m 15 cm = 1200 cm + 15 cm = 1215 cm
8 m 91 cm = 800 cm + 91 cm = 891 cm
The floor of the room is tobe paved with squared tiles. We need to find the length of the largest tile that can be used.
To find it we can find the HCF of 1215 cm and 891 cm.
Prime factorization of 1215 = 3 x 3 x 3 x 3 x 3 x 5
Prime factorization of 891 = 3 x 3 x 3 x 3 x 11
HCF = 3 x 3 x 3 x 3
= 81
Hence, the length of the largest tile that can be used is 81 cm.

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

The repeating decimals are both single digits, beginning at the decimal point. So, their equivalent is that digit divided by 9:
[tex]0.\overline{4}=\dfrac{4}{9}\\\\0.\overline{9}=\dfrac{9}{9}=1[/tex]
This means the given expression can be simplified to ...
[tex]\dfrac{3\sqrt{0.\overline{4}}+\sqrt{0.\overline{9}}}{\sqrt{3}}=\dfrac{3\sqrt{\dfrac{4}{9}}+\sqrt{\dfrac{9}{9}}}{\sqrt{3}}=\dfrac{3\cdot\dfrac{2}{3}+1}{\sqrt{3}}=\dfrac{3}{\sqrt{3}}=\boxed{\sqrt{3}}[/tex]

Answer: 6 pieces
=======================================================
Explanation:
3/4 = 6/8 after multiplying both parts by 2
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
10. The perimeter of a rectangle is 96m. Its length is double its breadth. Find its length and breadth.
11. Observe the following and identify the type of angles in them.
Answer:
breadth=16cm and length=32cm
Let breadth be X
According to question,
lengtg=2X
Now,
Perimeter=2(l+b)
or,96=2(2X+X)
or,96=2(3X)
or,96=6X
or,96/6=X
or,X=16cm.
length =32 cm and breadth =16 cm
Answer:
length = 32 cm, breadth = 16 cm
Step-by-step explanation:
let breadth be b then length is 2b, then
2b + 2(2b) = 96
2b + 4b = 96
6b = 96 ( divide both sides by 6 )
b = 16
Thus
breadth = 16 cm and length = 2 × 16 = 32 cm
