Answer:

The set of variables f and g

Step-by-step explanation:

we have to find the set of variables by which the bivariate data represents.

Bivariate data:

Data for two variables is known as bivariate data.

Eg: No. of Ice cream sold vs the temperature on that day. The two variables are the Ice Cream Sales and Temperature.

Bivariate analysis is one of the simplest forms of quantitative analysis involves the analysis of two variables for the purpose of determining the empirical relationship between them i.e relation between two variables.

Hence, the set of variables are f and g.

Option D is correct.

The eastbound train travels 10 miles per hour faster than the westbound train. After 2 hours, they are 232 miles apart. At what

patriot [66]

Answer:

48,58

Step-by-step explanation:

Let The speed of the west bound train be x

Let the east bound train be x+10

The speeds can be calculated as follows

2(2x+10)= 232

4x + 40= 232

4x= 232-40

4x= 192

x= 192/4

= 48

Hence the speedof the west bound train is 48

The speed of the east bound train is 48+10

= 58

Given a line segment that contains the points A,B, & C in order, if AB = x + 12, and BC = 2x - 4, and AC = 26, find x.

Troyanec [42]

Answer:

x = 6

Step-by-step explanation:

If A, B and C lies on a straight line in order, then;

AB+BC = AC

x+12+2x-4 = 26

x+2x+12-4 =26

3x+8 = 26

3x = 26-8

3x = 18

x = 18/3

x = 6

Hence the value of x is 6

What is the quotient of the following division problem (x+ 1)÷(x^2 + 3x +2)

seraphim [82]

Note: Actually, the division problem should be in reverse order. It should be given as $(x^{2} +3x+2) / (x+1)$ ---------(i)

But according to the given problem (x + 1) / (x² + 3 x + 2).

Here, (x² + 3 x + 2) > (x + 1)

or, (x + 2) > 1

Concept: By using the property of division, if the numerator is less than the denominator then the quotient will always be 0 (zero)

Therefore the option (d) 0 will be the correct option.

Answer:

1680 kwhr

Step-by-step explanation:

See attached for explanation. I converted watt*hr to kW*hr by dividing by 1000.

Fans Bulbs

40 100

50 60 W

10 6 hours/day

20000 36000 W*hr/day

30 30 days/month

600000 1080000 W*hr/month

600 1080 kWhr/month

Total = 1680 kWhr/month
