JADA, DIEGO, AND ELENA EACH USE THE SAME SPINNER THAT HAS FOUR (NOT NECESSARILY EQUAL SIZED) SECTIONS MARKED A, B, C, AND D.

JADA SAYS, "THE PROBABILITY OF SPINNING B IS 0.3 BECAUSE I SPUN 10 TIMES, AND IT LANDED ON B 3 TIMES."
DIEGO SAYS, "THE PROBABILITY OF SPINNING B IS 20% BECAUSE I SPUN 5 TIMES, AND IT LANDED ON B ONCE."
ELENA SAYS, "THE PROBABILITY OF SPINNING B IS 2/7 BECAUSE I SPUN 7 TIMES, AND IT LANDED ON B TWICE."

Based on their methods, which probability do you think is most accurate? Explain your reasoning.

Answer:

X=7

Step-by-step explanation:

Both are equal angles( the little 2 arrows prove that) so we set up the equation like this

75=11x-2

We need to isolate x to solve for it so we add 2 to both side since it's the opposite of subtraction.

our equation will then look like this

77=11x

last but not least, we divide 11 to both sides since it's the opposite of multiplication which 11 and X are doing

the answer is 7

Answer:

The answer is 7212 views

Step-by-step explanation:

So, For the first day the number of views is 390

Second Day

30% increased of total views

390 × 30 ÷ 100 = 11.7 = 12

390 + 12 = 402

Third Day

30% increased of total views

402 × 30 ÷ 100 = 120.6 = 121

402 + 121 = 523

Fourth Day

30% increased of total views

523 × 30 ÷ 100 = 156.9 = 157

523 + 157 = 680

Fifth Day

30% increased of total views

680 × 30 ÷ 100 = 204

680 + 204 = 884

Sixth Day

30% increased of total views

884 × 30 ÷ 100 = 265.2 = 265

884 + 265 = 1149

Seventh Day

30% increased of total views

1149 × 30 ÷ 100 = 344.7 = 345

1149 + 345 = 1494

Eight Day

30% increased of total views

1494 × 30 ÷ 100 = 448.2 = 448

1494 + 448 = 1942

Ninth Day

30% increased of total views

1942 × 30 ÷ 100 = 582.6 = 583

1942 + 583 = 2525

Tenth Day

30% increased of total views

2525 × 30 ÷ 100 = 757.5 = 758

2525 + 758 = 3283

Eleventh Day

30% increased of total views

3283 × 30 ÷ 100 = 984.9 = 985

3283 + 985 = 4268

Twelth Day

30% increased of total views

4268 × 30 ÷ 100 = 1280.4 = 1280

4268 + 1280 = 5548

Thirteenth Day

30% increased of total views

5548 × 30 ÷ 100 = 1664.4 = 1664

5548 + 1664 = 7212

Thus, Total views did the video get over the course of the first 13 days is 7212 Views.

Explanation:

A set is "closed" for a particular operation if performing that operation on members of the set always gives a member of the set.

closed example

For example, the set {0, 1} is closed for multiplication:

  0 × 0 = 0

  0 × 1 = 0

  1 × 1 = 1 . . . all result values are members of the set

Performing multiplication on any two members of the set gives a member of the set.

__

not closed example

The same set {0, 1} is not closed for addition:

  0 +0 = 0

  0 +1 = 1

  1 +1 = 2 . . . not a member of the set

Performing addition on any two members of the set does not always give a member of the set.

_____

Additional comment

Sometimes you are asked to demonstrate closure of a particular set using a particular example. As we see with addition, above, some examples may seem to demonstrate closure, while another example may prove the set is not closed. In short, you can demonstrate that the set is closed for a particular operation on a particular example, but that does not demonstrate closure in general.

[tex] \frac{2 {}^{3} \times 3 {}^{4} \times 4}{3 \times 32 } [/tex]

Make everything in the form of exponet.

[tex] \frac{ {2}^{3} \times {3}^{4} \times {2}^{2} }{3 {}^{1} \times 2 {}^{5} } [/tex]

Use the rule.

[tex]a {}^{m} \times {a}^{n} = a {}^{m + n} [/tex]

[tex] \frac{2 {}^{3 + 2} \times {3}^{4} }{3 \times {2}^{5} } [/tex]

[tex] \frac{2 {}^{5} \times {3}^{4} }{3 \times {2}^{5} } [/tex]

Cancel out like Terms.

[tex] \frac{3 {}^{4} }{3} [/tex]

Use the property

[tex] \frac{a {}^{m} }{a {}^{n} } = {a}^{m - n} [/tex]

So we have

[tex]3 {}^{4 - 1} = 3 {}^{3} [/tex]

[tex]3 {}^{3} = 27[/tex]

Answer:

18/8 or as a mixed number 2 ¹/4

Step-by-step explanation:

just times 6/1 by 3/8 which is 18 over 8 and simplify it into 2 ¹/4

Hii! Goodafternoon/morning!

Your question is asking how much is 3/8 + 3/8 + 3/8 is.

Normally, we would find a common denominator. But since they are all the same fraction, we don't need to.

First we need to figure out what 6×3 equals. That is 18.

We can't multiply 6×8.

So

We have to write the fraction has

18/8

But thats not simplified. So we need to turn this into a mixed number.

18/8 simplified is 2 2/8

We need to simplify that again.

2 2/8 simplified is 2 1/4.

So the answer is

2 and 1/4.

1. The theoretical probability that a coin toss results in two heads showing is 25% :

The probability of a head showing the first time is 50%
The probability of getting a head twice is 50% x 50% = 25%

2. The experimental probability that a coin toss results in two heads showing is 28/100 (28%)

3. The theoretical probablity that a coin toss results in two tails showing is 25% ( 50% x 50% )

4. The experimental probability that a coin toss results in two tails showing is 30/100 (30%)

5. The theoretical probability that a coin toss results in one head and one tail showing is 25% (also 50% x 50%)

6. The experimental probability that a coin toss results in one head and one tail showing is 42/100 (42%)

7. The theoretical probabilities have a difference from experimental probabilities because theoretical probabilities are equal odds of happening, while experimental probabilities might be biased because we might get tails for example, 10 times in a row, which messed up the odds.

Answer:

Question 1: C. 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

Question 2: The volume is [tex]\frac{1}{12}[/tex] or 0.083333333

Question 3: The volume fo the solid figure is 234

Step-by-step explanation:

1. Volume of a rectangular prism = (length × width × height) cubic units

Length = 4 ×  [tex]\frac{1}{8}[/tex]

Width = 3 × [tex]\frac{1}{8}[/tex]

Height = 2 × [tex]\frac{1}{8}[/tex]

Volume = 4 ×  [tex]\frac{1}{8}[/tex] × 3 × [tex]\frac{1}{8}[/tex]  × 2 × [tex]\frac{1}{8}[/tex]

Volume = 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

So the correct option is:

C. 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

2.

We have to fold the shape into a rectangular prism, look at the picture

Volume of a right rectangular prism =  (length × width × height)

Length = [tex]\frac{1}{3}[/tex]

Width =  [tex]\frac{1}{3}[/tex]

Height = [tex]\frac{3}{4}[/tex]

Volume = [tex]\frac{1}{3}[/tex] ×  [tex]\frac{1}{3}[/tex]  ×  [tex]\frac{3}{4}[/tex]

Multiply [tex]\frac{1}{3}[/tex] times [tex]\frac{1}{3}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\dfrac{ 1 \times 1 }{ 3 \times 3 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]

Do the multiplications in the fraction [tex]\dfrac{ 1 \times 1 }{ 3 \times 3 }[/tex]

[tex]\dfrac{ 1 }{ 9 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]

Multiply [tex]\frac{1}{9}[/tex] times [tex]\frac{3}{4}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]

Do the multiplications in the fraction [tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]

[tex]\frac{3}{36}[/tex]

Reduce the fraction [tex]\frac{3}{36}[/tex] to the lowest terms by extracting and canceling out 3

Fraction form: [tex]\frac{1}{12}[/tex]

or

Decimal form: 0.083333333

So the volume of the right rectangular prism is [tex]\frac{1}{12}[/tex]

3. Look at the picture with the solid figure labeled

We can think of this shape as two different prisms ( A and B)

Volume of A = 4.5 × 6 × 6.5 = 175.5

Volume of B = 3 × 3 × 6.5 = 58.5

Total volume of the whole figure = 175.5 + 58.5

175.5 + 58.5 = 234

So the volume of the solid figure is 234

Answer:

$59,500

Step-by-step explanation:

Assuming you mean 40%:

Two ways:

$42,500 + ($42,500 x 0.4)

OR

$42,500 x 1.4

= $59,500

Using the normal distribution and the central limit theorem, it is found that:

P(x < 0.29) = 0.2981.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

Then, the mean and the standard error are given by:

[tex]\mu = p = 0.31[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.31(0.69)}{100}} = 0.04625[/tex]

The probability our sample is 29% orange candies or less is the p-value of Z when X = 0.29, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.29 - 0.31}{0.04625}[/tex]

[tex]Z = -0.43[/tex]

[tex]Z = -0.43[/tex] has a p-value of 0.2981.

Hence:
P(x < 0.29) = 0.2981.
