200 people with those email addys might be people you know. While collecting addys randomly is a random sample.

its straight forward

[tex]\begin{array}{ccll} \stackrel{cups}{sugar}&cookies\\ \cline{1-2} \frac{3}{4}&24\\[1em] x&18 \end{array}\implies \cfrac{ ~~ \frac{3}{4} ~~ }{x}~~ = ~~\cfrac{24}{18}\implies \cfrac{ ~~ \frac{3}{4} ~~ }{\frac{x}{1}}~~ = ~~\cfrac{4}{3}\implies \cfrac{3}{4}\cdot \cfrac{1}{x}=\cfrac{4}{3} \\\\\\ \cfrac{3}{4x}=\cfrac{4}{3}\implies 9=16x\implies \cfrac{9}{16}=x[/tex]

now, the fraction is not an improper one, thus we can't quite put it in a mixed format, unless you count 0 as its whole, then I guess we can say is [tex]0\frac{9}{16}=x[/tex]

Answer:B. 80 students like Nepali

 C. 75 students like Social Studies only

Step-by-step explanation: The total of the ratio = the total number of students

 2 + 3 = 5

 5 parts = 200 students

 1 part = 200 ÷ 5 = 40 students

 Therefore,the students who liked Nepali(2 parts) = 2 × 40 = 80

The students who liked Social Studies(3 parts) = 3 × 40 = 120

But since 45 students liked both subjects,then those who liked Social Studies only:

120 - 45 = 75

The answers are a) attached b) 80 and c) 75

A Venn diagram is an illustration that uses circles to show the relationships among things or finite groups of things.

Given that, In a group of 200 students, the ratio of students who like Nepali and Social studies is 2:3. If 45 students like both the subjects and 20 students like none of the subjects,

The total of the ratio = the total number of students

2 + 3 = 5

5 parts = 200 students

1 part = 200 / 5 = 40 students

b) Therefore, the students who liked Nepali(2 parts) = 2 × 40 = 80

c)  The students who liked Social Studies(3 parts) = 3 × 40 = 120

Since, 45 students liked both subjects, then those who liked Social Studies only:

120 - 45 = 75

Hence, The answers are a) attached b) 80 and c) 75

Answer:

◘ 12 pears

◘ 3 pineapples

◘ 10 kiwis

Step-by-step explanation:

Let [tex]x[/tex] be the number of pears bought.

Therefore:

• number of pears = [tex]x[/tex]

• number of pineapples = [tex]x - 9[/tex]

• number of kiwis = [tex]x - 2[/tex]

We know that the total cost was $13.50.

This means if she bought [tex]x[/tex] pears at $0.50 each, [tex](x - 9)[/tex] pineapples at $1.50 each, and [tex](x -2)[/tex] kiwis at $0.30 each, the total would be $13.50.

∴  [tex][x \times 0.50] + [(x-9) \times 1.5] + [(x-2) \times 0.3] = 13.50[/tex]

Expanding and multiplying:

⇒ [tex]0.5 x + 1.5x - 13.5 + 0.3x - 0.6 = 13.5[/tex]

Collect like terms:

⇒ [tex]2.3x -14.1 = 13.5[/tex]

Solve for [tex]x[/tex]:

⇒ [tex]2.3x = 13.5 + 14.1[/tex]

⇒ [tex]2.3 x = 27.6[/tex]

⇒ [tex]x = 27.6 \div 2.3[/tex]

⇒ [tex]x = \bf 12[/tex]

Therefore, she bought:

• 12 pears

•  [tex]x - 9[/tex] = 12 - 9 = 3 pineapples

• [tex]x - 2[/tex] = 12 - 2 = 10 kiwis

Marita bought 12 pears, 3 pineapples and 10 kiwis.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Let x the number of pears bought,

y the number of pineapples bought,

z the number of kiwis bought,

Given that, Marita bought 9 more pears than pineapples and 2 fewer kiwis than pears,

y + 9 = x

y = x -9 and

z + 2 = x

z = x - 2

We know that the total cost was $13.50.

This means if she bought  pears at $0.50 each,  pineapples at $1.50 each, and  kiwis at $0.30 each, the total would be $13.50.

∴  0.50x + 1.50y+ 0.30z = 13.50

Substitute the values of y and z in equation,

⇒ 0.50x + 1.50(x -9)+ 0.30(x - 2) = 13.50

Expanding and multiplying terms in equation,

⇒  0.50x + 1.50x -13.50+ 0.30x - 0.60 = 13.50

Rearrange the like terms and apply the arithmetic operation

⇒ 2.3x - 14.1 = 13.50

⇒ 2.3x = 13.50 + 14.1

⇒ 2.3x = 27.6

⇒ x = 27.6/2.3

⇒ x = 12

Therefore, the number of pears bought = 12

So, the number of pineapples bought = 12 - 9 = 3

And the number of kiwis bought = = 12 - 2 = 10

Hence, Marita bought 12 pears, 3 pineapples and 10 kiwis.

Answer:

8 if including the tube and 4 if just counting the roll of toilet paper itself.

Step-by-step explanation:

Well like the question says the diameter of the toilet paper is 12 cm full both including the toilet paper and the tube. But we are also told the tube has a Diameter of 4. Taking this into consideration we both know that the tube will never get smaller but we do know the roll will decrease in size by half so while keeping the diameter of the tube at 4 we evenly remove half of the other 2  and we are left with a diameter of 2 / 4 / 2 in which giving us a total diameter of 8 therefore the diameter now being 8.

Answer:

x = 60°

Step-by-step explanation:

A straight angle is bascially a line with a point marked in it. That is 180°. Supplementary angles add up to 180°. Like the two right angles on the top part of the image are supplementary, as well as the two angles on the bottom part of the image.

120° + x = 180°

x = 60°

The ratios of corresponding side lengths are not equal.

Therefore, Figure B is not a scale copy of Figure A.

Here, we have to determine if Figure B is a scale copy of Figure A, we need to compare the corresponding sides of the two triangles and check if the ratios of their side lengths are equal.

Figure A has side lengths: 3.6, 2, and 5.

Figure B has side lengths: 8.9, 4, and 11.3.

Let's check if the ratios of corresponding side lengths are equal:

Ratio of corresponding side lengths of A and B:

3.6 / 8.9 ≈ 0.4045

2 / 4 = 0.5

5 / 11.3 ≈ 0.4425

The ratios of corresponding side lengths are not equal.

Therefore, Figure B is not a scale copy of Figure A.

In order for two triangles to be scale copies of each other, all corresponding side lengths must have the same ratio.

Since the ratios of side lengths in Figure A and Figure B are not equal, they are not scale copies of each other.

The way that this action is going to affect the mean and the mean and the median value would be decreased than what it was supposed to be.

In a frequency distribution, the mean is the number that is used to represent the average of a group of data. To get the mean, you have to add up the numbers in the data set and divide by the total number in the data set.

The formula is fx/n

When the average of $4800 is removed from the data set, the mean is going to decrease by the number and the value of fx would also decrease. Hence we can conclude that it would cause the value to reduce.

The median is the middle value, it would also cause the median in the data set to be smaller than it was.

- DH is correct because a line is connecting the two points D and H as shown in the image, forming a line segment.

- ED is correct because a line is connecting the two points D and E, forming another line segment, as shown in the drawing.

- EH is incorrect because in the drawing shown, there is no line connecting the two points E and H, so there would be no line segment formed between these two points.

- CD is correct because there is another line connecting the two points C and D, forming another line segment in the drawing.

Therefore, lines DH, ED, and CD are all line segments.
