Answer:
if there are no typos, line is y=0
Step-by-step explanation:
slope intercept form is y=mx+b
m= slope
b= y intercept
slope is found by y2-y1 / m2-m1
so using the points (-1, 0) and (-5, 0)
(0-0) / (-5 - -1)
= 0/ -4
= 0
m=0
y=0x+b
plug in a point to find b
0=0*-1 +b
b=0
The line is just y=0

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.
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.

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]

B.) a^2 – b^2= c^2
C.) a^2 + b^2= c^2
D.) a^2 = b^2 + c^2
Answer:
C
Step-by-step explanation:
It is C. because it is the formula for Pythagorean theorem.

help me pls !! i don’t understand
Pls help. question is in the picture above
Answer:
15 meters
Step-by-step explanation:
Because angle BFD and angle DFC are supplementary (they form a 180 degree angle, as you can see from the fact that they both form a straight line) and angle BFD is 90 degrees, angle DFC must also be 90 degrees. Since it is 90 degrees, you can use the Pythagorean theorem to solve for DF as a part of triangle DFC=> 8^2(x^2)=17^2.
=>64(x^2)=289
subtract 64 from both sides=> x^2=225
take the square root of both sides=> x=15
Since triangles BED and BFD are equal by way of angle-side-angle, we know that all of their corresponding sides and angles are equal, and therefore, DF=DE, so DE=15 meters

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.

Answer:
C) √3
Step-by-step explanation:
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:
(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
