Which of the following statements about the mapping is not true?
Answer:
C. The mapping represents a relation but not a function
Step-by-step explanation:
✔️The relation is a function because every input value (domain) is mapped to exactly one output value (range). So option A is TRUE.
✔️The range consist of 2 and 1 (output values).
Option B is TRUE
✔️In the domain (input value), we have 3, 6, 7.
Option D is TRUE
Only option C is NOT TRUE.

What is the volume of this solid?
O A. 39,000
B. 63,000
C. 100,800
D. 27,000
Answer:
A. 39,000.
Step-by-step explanation:
Volume of the lower prism = 30^3= 27,000
Volume of the pyramid = 1/3 area of the base * height
= 1/3 * 900 * 40
= 1200
Volume of the whole solid = 27000 + 12000
= 39,000,

4x-3y<16, which ordered pair?
Answer:
A. (3, -1)
Step-by-step explanation:
The ordered pair that is a solution is the one which makes the inequality TRUE when the value of the ordered pairs are plugged into 4x - 3y < 16
Therefore, the ordered pair, (3, -1) is the solution because it is the only given ordered pair in the options that makes the inequality true. Thus:
Substitute x = 3 and y = -1 into 4x - 3y < 16
4(3) - 3(-1) < 16
12 + 3 < 16
15 < 16 (TRUE)
A car with 12 gallons of gasoline drives 312 miles until the tank is empty.
Write a linear equation that describes the amount of gas left in the car, y, after driving x miles.
The linear equation is ________________. (Type your answer in slope-intercept form. Use integers or simplified fractions for any numbers in the expression.) *
Answer:
The linear equation is 312 - (312/12) X = Y.
Step-by-step explanation:
Given that a car with 12 gallons of gasoline drives 312 miles until the tank is empty, to determine a linear equation that describes the amount of gas left in the car, Y, after driving X miles, the following calculation must be performed:
312 - (312/12) X = Y
312 - 26X = Y
So, for example, if you were driving 4 miles, the equation would work as follows:
312 - 26 x 4 = Y
312 - 104 = Y
208 = Y

Find mean and median of un grouped data 3,12,8,17,10,16
Answer:
mean=sum of data /no of data
=66/6
=11
mean=11
for median u should arrange the data from ascending to descending order.so,
3,8,10,12,16,17
median=N+1/2(N=number of data)
=7/2
=3.5
=3 rd term + 4 th term/2
=10+12/2
=22/2
=11
median=11
Step-by-step explanation:
Answer:
mean: 11
median: 11
Step-by-step explanation:
3,12,8,17,10,16
average = (3 + 12 + 8 + 17 + 10 + 16)/6 = 66/6 = 11
3,8,10,12,16,17
median = 11
centre numbers are 10 and 12, and their sum/2 = 11

Jada walks dogs to earn money. The points in this graph represent the total amount of money Jada earns based on the number of hours she walks dogs. Jada wants to purchase a new jacket that costs $32.
How many hours does Jada need to walk dogs to earn enough money to buy the jacket?
Answer:
Eight Hours.
Step-by-step explanation:
Since she makes 4$ in 1 hour, you divide 32 by 4 to see how many hours it would take her.
32 divided by 4 = 8
Jada needs 8 hours to walk dogs to earn enough money to buy the new jacket which costs $32.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Jada wants to purchase a new jacket that costs $32.
Since she makes 4$ in 1 hour
So, Time is taken to earn money to 4$ = 1 hour
Time is taken to earn money to1$ = 1/4hour
Time is taken to earn money to 32$ = 32/4hour
= 8 hour
Thus, Jada needs 8 hours to walk dogs to earn enough money to buy the jacket.

if 3x^2+3y^2=42 and xy =-15.Find the value (x-y)^2
Answer:
44
Step-by-step explanation:
Given, 3x^2 + 3y^2 = 42
=>3(x^2 + y^2) = 42 =>x^2 + y^2 = 42/3= 14
Thus,
= (x - y)^2
= x^2 + y^2 - 2xy
= (x^2 + y^2) - 2xy

Part 3a. NO LINKS. Find the measure of the arc or angle indicated.
9514 1404 393
Answer:
99°
Step-by-step explanation:
Arc YZ is twice the measure of angle X, so is 136°. The sum of the arcs of a circle is 360°, so the unknown arc is ...
360° -136° -125° = 99° . . . . measure of arc XZ
Answer:
Solution given:
<x=68°
arc XY=125°
arc XZ=?
we have
<X+<W=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]
<W=180°-68°=112°
Now
arc YZ=2×112°=224°[central angle is equal to the twice of its inscribed angle]
arc YZ=224°
arc XY +arc YZ=224°
125°+arc YZ=224°
arc YZ=224°-125°
arc YZ=99°
the measure of the arc or angle indicated is 99°.
