Answer:
Option 2: none of these
Step-by-step explanation:
-x +2y= 4
x-intercept occurs at y=0.
When y=0,
-x +2(0)= 4
-x= 4
x= -4
Thus, x-intercept is (-4,0).
y-intercept occurs at x=0.
When x=0,
0 +2y= 4
2y= 4
y= 4 ÷2
y= 2
Thus, y-intercept is (0,2).
*When writing coordinates, the x and y coordinates are separated by a comma in the bracket. If the 3rd option is a comma instead of a dot (which could instead denote a multiplication sign), it would be the correct option.
In RST , if RT ST , mR = (9x + 2)°, mS = (13x – 18)°, and mT = (17x + 1)°, find x and the
measure of each angle.
Answer:
x = 5
<R = 47 degrees
<S = 47 degrees
<T = 86 degrees
Step-by-step explanation:
The sum of angles in a triangle is 180degrees
Given triangle RST
<R + <S + <T = 180
9x + 2 + 13x - 18 + 17x +1 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 195/39
x = 5
Get <R
<R = 9x + 2
<R = 9(5) + 2
<R = 47 degrees
Get <S
<S = 13x-18
<S = 13(5) - 18
<S = 65-18
<S = 47 degrees
Get <T
<T = 17x + 1
<T = 17(5)+1
<T = 85+1
<T = 86 degrees

3/4 + -3/8 + -1/4=?
Evaluate the expression
Answer: -1/8
Step-by-step explanation:
3/4 + -3/8 + -1/4
Find the LCM of 4, 8, and 4
That's 8 so you make an equivalent fraction for all fractions so the denominator is 8.
3/4 = 6/8
-3/8 = -3/8
-1/4 = -4/8
Now the expression looks like this:
6/8 + - 3/8 + -4/8
6/8 - 3/8 - 4/8
6/8 - 7/8
-1/8

A different aquarium should contain 15,000 liters of water when filled correctly. It will overflow if it gets to 17,600 liters.
One day there is an accident and the tank cracks in 4 places. Water flows out of each crack at a rate of liter per hour. An emergency pump can re-fill the tank at a rate of 2 liters per minute. How many minutes must the pump run to replace the water lost each hour?
Step-by-step explanation:
How much hours have passed?
In the figure, solve for x and y.
Answer:
y=124°
x=67°
Step-by-step explanation:
For the triangle on the right
180-74-50=56°
then y= 180-56=124°
For the triangle on the middle (that small triangle)
180-85(Head opposite angles)-50=45°
So
x=180-45-68=67°
The employment status (employed or unemployed) of each individual in the U.S. workforce is a set of data that is of interest to economists, businesspeople, and sociologists. To obtain information about the employment status of the workforce, the U.S. Bureau of the Census conducts what is known as the Current Population Survey. Each month interviewers visit about 59,000 of the 98 million households in the United States and question the occupants over 14 years of age about their employment status. Their responses enable the Bureau of the Census to estimate the percentage of people in the labor force who are unemployed (the unemployment rate).
Question Completion:
(a) Identify the experimental unit.
(b) Define the population of interest to the Census Bureau.
(c) Identify the sample.
(d) What variable is being measured? Is it quantitative or qualitative?
(e) Describe the statistical inference that the economists intend to make.
Answer:
a. The experimental unit is the households visited.
b. The population of interest to the Census Bureau is all US-based individuals aged 14 and above.
c. The sample is 59,000 households.
d. The variable under measure is quantitative (percentage estimate of people in the labor force who are unemployed).
e. The economists want to make a statistical inference of the unemployed population based on the sample data analysis that they conduct.
Step-by-step explanation:
a) Data and Calculation:
Population of interest = 98 million households
Sample from population = 59,000 households
b) The unemployment rate is the percentage of the total workforce of a country that is unemployed and who may be actively seeking employment at a particular period. This implies that the unemployment rate may include persons who are active members of the workforce but may be underemployed.

Step-by-step explanation:
A machine cell uses 204 pounds of a certain material each day. Material is transported in vats that hold 34 pounds each. Cycle time for the vats is about 2.25 hours. The manager has assigned an inefficiency factor of .17 to the cell. The plant operates on an eight-hour day. How many vats will be used
Answer: 2 Vats will be used
Step-by-step explanation:
using the formula below, the ideal number of Kanban cards can be calculated;
N = (DT × ( 1 + X)) / C
where N is total number of container,
D is panned usage rate of using work Centre
T is Average waiting time for replenishment of parts plus average production for a container of parts,
X is policy variable set by management that reflects possible inefficiency in the system ,
C is capacity of standard container.
Now, in the question, we were given that;
D = 204 pounds per day = 204 / 8hrs = 25.5 pounds/hr { The plant operates on an eight-hour day}
T = 2.25 hrs
X = 0.17
C = 34 pounds each
we substitute
N = (25.5×2.25 × ( 1 + 0.17)) / 34
N = 67.12876 / 34
N = 1.974375 ≈ 2 Vats
Therefore 2 Vats will be used.
Write an equation of the line that passes through (5, −1) and is perpendicular to the line y=12x−1.
Step-by-step explanation:
solution
let,A(5,-1)
given
y=12x-1
or, y = 12 × x + (-1)
comparing it with y=mx+c
we get
x=1
y = c = -1
now
A(5,-1) and B(1,-1)
equation of line is,
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
or, (y+1)/(x-5) = (-1+1)/(1-5)
or, (y+1)/(x-5) = 0/-4
cross multiply
-4y-4 = 0
or, 0=4y+4
or, 4y+4=0 is the required eqn
I think this is the process and answer too.
I hope this helps you

Step-by-step explanation:
Answer:
4%
Step-by-step explanation:
The stock of Company A gained $1.32 throughout the day and ended at a value of $34.32. By what percentage did the stock rise?
\text{New value: }\$34.32
New value: $34.32
\text{Old value: }34.32-1.32=\$33.00
Old value: 34.32−1.32=$33.00
33(1+r)=34.32
33(1+r)=34.32
\frac{33(1+r)}{33}=\frac{34.32}{33}

PLS HELP!! A student randomly guesses the answers to two true-false questions. Describe and correct the error in finding the probability of the student guessing both answers correctly. The student can either guess two incorrect answers, two correct answers, or one of each. So the probability of guessing both answers correctly is 1/3
Answer:
The student was wrong. The probability is actually 1/4.
Step-by-step explanation:
Let's say you have question A and question B. You could have incorrect on A, and incorrect on B. Or, you could have incorrect on A, but a correct on B. Or, you could have an incorrect on B, but a correct on A. Or, both could be correct. Since there are 4 different possibilities, the actual probability is 1/4.
