the answer is D, 1/20

Step-by-step explanation:

i got it wrong the first time but just look at the correct answer choice

The experimental probability is 1/20 that a piece of paper randomly drawn from the bowl will have the number 35 written on it.

A stem-and-leaf diagram is a quantitative assessment of a collection of data in which the data values are divided into a "stem" (the first digit of the number) and a "leaf" (the remainder of the number) (the last digit of the number).

As per the given stem-and-leaf plot, the required solution would be as:

First, determine the total number of pieces of paper pulled from the bowl by totaling the entries in the stem-and-leaf plot.

The stem-and-leaf layout has 40 numbers, with two of them being 35.

As a result, two of the forty pieces of paper drawn had the number 35 scrawled on them.

So, the experimental probability of the piece of paper having 35 on it is :

2/40 = 1/20.

Answer:

Step-by-step explanation:

Step-by-step explanation:

b = 147° ( vertically opposite angle )

c + 147 ° = 180° ( supplementary angle )

c = 180° - 147°

c= 33°...

Answer:

Step-by-step explanation:

b = 147°    {Vertically opposite angles are congruent}

Linear pair: A linear pair is a pair of adjacent angles whose non-common arms form a line ( opposite rays)

c + 147 = 180          {Linear pair}

         c = 180 - 147

c = 33°

Answer:

No. Only 1 to 100, logically.

Let's make a scenario to solve this.

So let's say I have an all yellow, 9 quarter spinner board and I spin. It will always land on yellow, so it has a 9/9 or 100% chance of landing on yellow.

Now we must create another scenario.

For instance, I have one bottle, its starting direction was North, and I spin it. It will have a 1/4 chance of landing on North, East, South, or West because it will land in a random direction. For the 4 diagonal directions southeast, southwest, northeast, northwest it will be the same because there are only 4 directions, therefore giving the probability a 1 in 4 chance of landing on either one. :)

The area of the regular heptagon which has a radius of approximately 27.87 cm and the length of each side is 24.18 cm is 2125 cm².

Heptagon is the closed shape polygon which has 7 sides and 7 interior angles.

The area of the regular heptagon is found out using the following formula.

[tex]A=\dfrac{7a}{4}\cot \left(\dfrac{180}{7}\right)[/tex]

Here, (a) is the length of the heptagon.

A regular heptagon has a radius of approximately 27.87 cm and the length of each side is 24.18 cm. Put the value of side in the above formula,

[tex]A=\dfrac{7\times24.18}{4}\cot \left(\dfrac{180}{7}\right)\\A\approx 2125\rm\; cm^2[/tex]

Hence, the area of the regular heptagon which has a radius of approximately 27.87 cm and the length of each side is 24.18 cm is 2125 cm².

The radius of the toy ball is 24.5 millimeter (to nearest tenth)

Let, r be the radius of the sphere.

Then the surface area of the sphere = [tex]4\pi r^{2}[/tex] sq. unit

The structure of the toy ball is sphere.

Given, Surface area of the toy ball = 7543 square millimeter

Let, the radius be r millimeter

∴  [tex]4\pi r^{2}[/tex] = 7543

⇒ [tex]r^{2}[/tex] = [tex]\frac{7543}{4*3.14}[/tex]  , where [tex]\pi[/tex] = 3.14

⇒  [tex]r^{2}[/tex] = [tex]\frac{7543}{12.56}[/tex]

⇒  [tex]r^{2}[/tex] = 600.56

⇒ r = [tex]\sqrt{600.56}[/tex]

⇒ r = 24.5 (approx)

Radius = 24.5 millimeter (to nearest tenth)

Area of triangle

Multiplication property of equality

Substitution property of equality

Step-by-step explanation:

Hope this helps

So, it is proven that the area of triangle ABC is  [tex]\frac{1}{2} * a*b*SinC[/tex].

A triangle is a 2D shape having three sides and the sum of all angles is 180°.

We have,

A ΔABC,

And,

AB = c

BC = a

CA = b

H = Altitude of the triangle,

Now,

Area of triangle [tex]=\frac{1}{2} * Base *Altitude[/tex]

i.e.

Area of triangle ABC [tex]=\frac{1}{2} * a*h[/tex]     .....(i)

Now,

Using trigonometric ratios,

[tex]Sin C = \frac{Perpendicular}{Hypotenuse}[/tex]

i.e.

[tex]Sin C = \frac{h}{b}[/tex]

We get,

h = b * SinC

Now,

putting this value in equation (i),

We get,

Area of triangle ABC [tex]=\frac{1}{2} * a*b*SinC[/tex]  

So,

It is proved that area of triangle ABC [tex]=\frac{1}{2} * a*b*SinC[/tex] ,

Hence, we can say that it is proven that the area of triangle ABC is  [tex]\frac{1}{2} * a*b*SinC[/tex], using trigonometric ratios and the triangle's area formula.

Answer:

24 boxes in 4 packs.

36 boxes in 6 packs.

60 boxes in 10 packs.

600 boxes in 100 packs.

Step-by-step explanation:

If 6 boxes are in 1 pack and 12 in 2, you can use a ratio, which is 1:6 meaning for every 1 pack are 6 boxes.

There are two ways you can get an answer

Multiplication:

For however many packs there are you multiply it by 6 boxes.

For 4 packs, you multiply it by 6 boxes. You would get 24 boxes.

For 6 packs, you multiply it by 6 boxes again getting 36 boxes.

Below is a table I made for an example.

6 | 36

10 x 6 is 60

100 x 6 is 600.

whenever the multiplier starts with 1 and ends in 0, just add the number of zeros behind that number. Example: 7 x 1,000,000 = 7,000,000

Answer:

  (a)  Grade 6

Step-by-step explanation:

You want to know which grade (6 or 7) has the higher mean score, based on the given dot plots.

The scores of Grade 6 range from 70 to 100. Those of grade 7 range from 50 to 80.

Both distributions are approximately symmetrical, but have slightly more scores farther below the middle of the range than above. This means the mean in each case will be slightly below the middle of the range.

Even so, the mean of Grade 6 scores will be substantially above the mean of Grade 7 scores. Grade 6 has the higher mean score.

__

Additional comment

Assume the mean of Grade 6 is 85, the middle of the range of scores. Subtract the fewest number of dots (4) from each column, and we have 2 scores 15 units below that assumed mean, and 2 scores at 5 units above that assumed mean. The total of these is 2(-15) +2(+5) = -20. This tells us the actual mean of Grade 6 scores is -20/20 = -1 from the assumed mean of 85. The Grade 6 mean is 84. This is higher than any Grade 7 score, so Grade 6 must have the higher mean.
