Answer:

1x + 4y = 4 ⇒ 6x + 24y = 24

6x -  8y = 0 ⇒ 6x -   8y = 0

Answer:

x27 + y.

Step-by-step explanation:

Binomial means having 2 terms so binomial of degree 27 is x^27 + y type.

For example,

x^27+y+2

If there are 2 degree terms of x, degree of the one having highest degree is taken.

For example,

In x^27+x^10

As highest degree is 27, this is a binomial of degree 27.

Step-by-step explanation:

1) Find the Mean of 7  18  9  22  4.

7 + 18 + 9 + 22 + 4 = 50

50 ÷ 5 = 10

2) Find the Median of 7  18  9  22  4.

4  7  9  18  22

The Median is 9.

3) Find the Mean of 7  3  7  4  8  9  2.

7 + 3 + 7 + 4 + 8 + 9 + 2 = 40

40 ÷ 7 = 5.7

4) Find the Median of 7  3  7  4  8  9  2.

2  3  4  7  7  8  9

The Median is 7.

5) Find the Mode of 7  3  7  4  8  9  2.

Mode is the number that occurs the most.

2  3  4  7  7 8  9

The Mode is 7.

6) Find the Median of 6  10  23  24  13  9  23  12.

6  9  10  12  13  22  23  24

There are 8 numbers in this set of numbers, so the Median is the average of the two numbers in the middle. So, [tex]\frac{(12+13)}{2} = \frac{25}{2} = 12.5[/tex]

The Median is 12.5.

7) Find the Mean of  6  10  23  24  13  9  23  12.

6 + 10 + 23 + 24 + 13 + 9 + 23 + 12 = 120

120 ÷ 8 = 15

The Mean is 15.

8) Find the Median of 120  113  101  101  112.

101  101  112  113  120

The Median is 112.

9) Find the Mean of 73  72  72  98  99  96  98  98  73.

73 + 72 + 72 + 98 + 99 + 96 + 98 + 98 + 73 = 779

779 ÷ 9 = 86.6.

10) Find the Mode of 73  72  72  98  99  96  98  98  73.

72  72  73  73  96  98  98  98  99

The Mode is 98.

The Median is 96.

13) Find the Median of 12  22  26  15  18  22  29  11  22  18.

11  12  15  18  18  22  22  22  26  29

There are 10 numbers in this set of numbers, so the Median is the average of the two numbers in the middle. So, [tex]\frac{(18+22)}{2} = \frac{40}{2} = 20[/tex]

The Median is 20.

Step-by-step explanation:

Remark

If you take one radius whose length is r and start it at (0,0) on one end and (r,0) at the other, and sweep it around so the (r,0) hits every point on the circumference of the circle, the radius will go through 360°.

You have only gone through 120°. That's no problem. All you have to do now is add a fraction that adjusts for the 120°.

Formula

Arc length = fraction * 2*pi * r

2*pi * r is the circumference

Arc Length = 2* (120/360) * pi * r

Givens

r = 13

pi = 3.14

Solution

Arc Length = (120/360) * 2 * pi * 13

Arc Length = 27.21

Answer

Arc Length = 27.21

Answer:

The number of students who collected exactly 9 bottles.

Step-by-step explanation:

The given histogram shows the number of students who participated in the recyling drive & their old bottle waste collection.

We can find out the total number of students who participated just by looking at the histogram (students = 10), the number of students who colected bottles below 7 or 3 bottles etc.

But since the number of bottles is given in the form of grouped data, one cannot infer the exact number of bottles collected by students.

Hence, out of the given statements, 'The number of students who collected exactly 9 bottles' is the incorrect one.

Explanation:

There are a few ways to measure the period. One way is to measure the horizontal distance from peak to peak.

The left peak occurs at x = 1

The right peak occurs at x = 17

This is a horizontal distance of 17-1 = 16 units.

Therefore, the period is 16. The curve repeats itself every 16 units.

The probability that in a given year it will not snow on January 1st will be P = 0.915.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Since the total probability is always equal to 1 if the probability of happening of an event is given then the probability of not happening of an event will be determined by subtracting it from one.

The probability of not any snowfall will be calculated as:-

P = 1 - 0.315

P = 0.615

Therefore the probability that in a given year it will not snow on January 1st will be  P = 0.915.

The statement (B) "The median for town A, 30°, is less than the median for town B, 40 degree" is correct.

A box and whisker plot is a method of abstracting a set of data that is approximated using an interval scale. It's also known as a box plot. These are primarily used to interpret data.

From the data given:

For town A and Town B

As we can see in the box plot

The median for town A = 30 degree

Median for town B = 40 degree

The median for the town, A < Median for town B

Thus, the statement (B) “The median for town A, 30°, is less than the median for town B, 40 degree” is correct.

The correct choice for this question is Option B

Step-by-step explanation:

Volume of cylinder = π.r^2.h

h = 5 inch, r = 6 inch, π = 3.14

Ruler Postulate

Step-by-step explanation:

In box 1, the reason that justifies the statement, m∠BAD = m∠BAC + m∠CAD, is: angle addition postulate.

The angle addition postulate states that the measure of a larger angle equals the sum of smaller angles that make up the larger angle.

∠BAD comprises of ∠BAC and ∠CAD.

Therefore, based on the angle addition postulate, m∠BAD = m∠BAC + m∠CAD.
