At the beginning of the 20th century, they were built to compete against roads by offering greater road flexibility, and the further calculation can be defined as follows:
The software program in each collection of 78 workers would be likely to be drawn from the software. This kind of huge autonomous, wheeled car, usually on a fixed route, is used to transport passengers. The bus company management wants to look into the new uniforms for staff. The manager draws 78 people at random with such a computer program and selects those. The stratified sampling of employees can ideally be drawn from the set of 78 employees through the computer program.Following are the description of the wrong choice.
In option b, it is wrong because creating a group of employees is not good because after that we select the employee randomly.In option c it is wrong because in this question we select employees only.Therefore, "Option a" is correct.

Ezekiel decomposed the rectangle shown into three smaller rectangles. Then he demonstrated the Distributive Property by modeling the area of the entire rectangle in terms of the three smaller rectangles. Which equation could Ezekiel have used?
answer choices:
1. 21(3 + 3) = 21(3) + 21(3)
2. 6(6 + 12 + 3) = 6(6) + 6(12) + 6(3)
3. 21(3 + 2 + 3) = 21(3) + 21(2) + 21(3)
4. 6(10 + 10 + 11) = 6(10) + 6(10) + 6(11)
Answer:
2. 6(6+12+3) = 6(6)+6(12) + 6(3) = 36+72 + 18 = 126 unit square
Area = 126 unit square.
and satisfies the 3 rectangle area. However can such amounts fit inside the rectangle as distributable?
We prove length of 21 units =
21-6 = 15 Units length and 15 - 12 = 3. Proves all 3 measures of length does fit within the length of 21 units length
Conclusion Does satisfy as three length measures within one larger measure given for the large rectangle fit exact, to find area identical in totals.
Step-by-step explanation:
Proof area of 21 x 6 area rectangle = 126unit square
3 smaller rectangles made from same larger rectangle must = 126 unit square when all 3 smaller area are added together.
answer choices
1. 21(3+3) = 2(3)+21(3) only shows 2 rectangles area = 2 rectangles angle
Does not satisfy
2. 6(6+12+3) = 6(6)+6(12) + 6(3) = 36+72 + 18 = 126 unit square and satisfies the 3 rectangle area. However can such amounts fit inside the rectangle as distributable?
We prove length of 21 units =
21-6 = 15 Units length and 15 - 12 = 3. Proves it does fit within the width of 21 units length
Conclusion Does satisfy as three length measures within one larger measure given for the large rectangle fit exact, to find area identical in totals.
3. 21 (3+2+3) = 21 (3) +21 (2)+21 (3) does not satisfy 6 units width as 3+2+3 = 8 and is too high a number. Does not satisfy.
4.6(10+10+11) = 6(10) + 6(10) + 6(11) does not satisfy
The lengths of the three rectangles adds to 31 length as 10+10+11 = 31 instead of 21. Does not satisfy.

Which is the best estimate for the capacity of a glass vase?
A. 200 ml
B. 500 ml
C. 5,000 ml
D. 5,000 kl
Answer:
D, x = 3
Step-by-step explanation:
to know if a line is parallel, we need to know what kind of line x = 6 is
we can use the mnemonic VUX/HOY to determine the slope, the type of line, and which axis it corresponds to. VUX/HOY stands for:
Vertical line
Undefined slope
X axis
Horizontal line
0 is the slope
Y axis
according to this, the equation x = 6 is a vertical line
now we can start eliminating answer choices
A. a line containing the point (6,2)
the point lies on the line x = 6, as the x-coordinate in the ordered pair is 6. this is not parallel to the line
B. y = 6
this intersects x = 6 and is not parallel
C. y = 4
this intersects x = 6 as well and is not parallel
D. x = 3
this leaves us with x = 3, which is a vertical line as seen by the equation and therefore x = 3 is our answer

A motorboat travels 448 kilometers in 8 hours going upstream and 440 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
9514 1404 393
Answer:
boat: 72 km/hcurrent: 16 km/hStep-by-step explanation:
The speed difference between boat and current is the upstream rate:
(448 km)/(8 h) = 56 km/h
The sum of speeds of boat and current is the downstream rate:
(440 km)/(5 h) = 88 km/h
The rate of the boat is half the sum of these:
(56 +88)/2 = 72 . . . km/h
The rate of the current is half their difference:
(88 -56)/2 = 16 . . . km/h
The rate of the boat is 72 km/h; the rate of the current is 16 km/h.

Jacob took a total of 4 quizzes over the course of 3 weeks.
How many weeks of school will Jacob have to attend this quarter before he will have taken 16 quizzes?
Answer:
The answer would be a total of 12 weeks .
Step-by-step explanation:
Because the first four test were in a total of three weeks
so in order to find out how many weeks for 16 quizzes just multiply
4 quizzes -3 weeks
8 quizzes -6 weeks
12 quizzes - 9 weeks
16 quizzes - 12 weeks
SO just multiply 4 by 4 and multiply 4 by 3

For which other positive integers a, less than 11, will the number (a^n) + (a^n+1) + (a^n+2) + (a^n+3) + (a^n+4) always be divisible?
Pls, Answer with the entire explanation.
If the number is supposed to be
[tex]a^n + a^{n+1} + a^{n+2} + a^{n+3} + a^{n+4}[/tex]
then it can be factorized as
[tex]a^n \left(1 + a + a^2 + a^3 + a^4\right)[/tex]
but there's not much to say about divisibility here without any more information about a.
If you meant
[tex]a^n + (a^n+1) + (a^n+2) + (a^n+3) + (a^n+4)[/tex]
simplifying gives
[tex]5a^n + 10 = 5 (a^n+2)[/tex]
which is clearly divisible by 5.
Trey wrote a few steps to describe how carbon circulates between the atmosphere and living organisms. Step 1. Carbon enters the atmosphere as carbon dioxide from respiration and the burning of fossil fuels. Step 2. Plants absorb carbon dioxide in the air and use it to make their own food using photosynthesis. Step 3. Plant-eating animals consume the carbon stored in plants. If step 2 is removed, which statement best describes the effects of this missing step on the carbon cycle?
Answer:
Dead animals are buried and form fossil fuels, which produce carbon dioxide when burned.
When animals and plants are fossilized and buried under sediments, the higher pressure and temperatures turns them to oil, over time, that is mined and combusted for energy by humans. This plays a significant role in the carbon cycle.
The best statement describing the effects of missing step 2 in Trey's description of the circulation of carbon between the atmosphere and living organisms is: there will be too much carbon dioxide in the atmosphere.
Carbon dioxide in the atmosphere is mostly used by plants to create their food through the well-known process of photosynthesis.
Without step 2, carbon dioxide will not be absorbed by plants through photosynthesis. Therefore, the amount of carbon dioxide present in the air will be too much for other living things and animals. The side effects include:
increase in global warming unsavory increase in ozone depletion worsening global environmental disasterslack of fossil fuel.
Thus, step 2 is an indispensable, necessary, important, and life-saving process in the carbon cycle.

Inverse for f(x)=1/2x+3
Answer: [tex]f^{-1}(x)=2x-6[/tex]
Step-by-step explanation:
To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.
[tex]y=\frac{1}{2}x+3[/tex] [switch x and y]
[tex]x=\frac{1}{2}y+3[/tex] [subtract both sides by 3]
[tex]x-3=\frac{1}{2} y[/tex] [multiply both sides by 2]
[tex]y=2x-6[/tex]
Now, we know that [tex]f^{-1}(x)=2x-6[/tex].

-3x + 6y = 18
-3x = 6y+14
a) What is the slope of the 1st equation?
b) What is the slope of the 2nd equation?
c) Are they parallel, perpendicular, or neither?
Step-by-step explanation:
-3x + 6y = 18
-3x = 6y+14
a) the slope of the 1st equation = -(-3)/6 = ½
b) the slope of the 1st equation = -3/6 = -½
c) they are niether parallel nor perpendicular
Answer:
a) ¹/₂
b) -¹/₂
c) neither
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptGiven equations:
[tex]\begin{cases}-3x+6y=18\\-3x=6y+14 \end{cases}[/tex]
To find the slopes of the given equations, rearrange them to make y the subject then compare with the slope-intercept formula:
Equation 1
[tex]\begin{aligned}-3x+6y & = 18\\6y & = 3x + 18\\y & = \dfrac{3x+18}{6}\\\implies y & = \dfrac{1}{2}x+3\end{aligned}[/tex]
Therefore, the slope of Equation 1 is ¹/₂.
Equation 2
[tex]\begin{aligned}-3x & = 6y+14\\6y & = -3x-14\\y & = \dfrac{-3x-14}{6}\\\implies y& = -\dfrac{1}{2}x-\dfrac{14}{6}\end{aligned}[/tex]
Therefore, the slope of Equation 2 is -¹/₂.
Parallel slopes have the same slope.
Perpendicular slopes are at right angles to each other and therefore the product of their slopes is -1 (negative reciprocals of each other).
Therefore, the slopes of Equation 1 and Equation 2 are neither parallel or perpendicular.
Solve the equation.
