13 over 11 equals 4 over u

Answer:

45 minutes

Step-by-step explanation:

Assume task completed in total x hours

[tex]\frac{x}{10} + \frac{3}{8} + \frac{3}{12} = 1 \\ 12x + 45 + 30 = 120 \\ 12x = 45 \\ x = \frac{15}{4} = 3 \frac{3}{4}[/tex]

So q will take 45 more minutes

An example of theoretical probability from the considered option is given by: Option 2: A spinner has 8 equal sections numbered 1 to 10. The probability of spinning the number 3 is 1/8

Experimental probability calculates the probability of some event from the results of experiments.

For an event E, we get the experimental probability of that event

[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]

where, [tex]P_e(E)[/tex]is denoting experimental probability of occurrence of E.

Probability which is derived theoretically, irrespective of what outcome comes, is called theoretical probability. Probabiltiy which is based on the outcomes of experiments performed is called experimental probability.

Suppose we want to find the probability of an event E.

Then, its theoretical probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

Checking all the options to see which one gives theoretical probability:

This option uses what was observed from one result. Thus, 3/5 is experimental probability here, as there is no evidence of it being theoretical probability but enough support towards being experimental probability.

No experiment is done here, just the description of the setup of the random experiment.

Now, E = event of getting 3 on the spinner.

All spinner's parts are assumingly equally likely, we have:

Number of ways E can occur = 1

Number of ways spinner's outcome can come = 8

Thus, we get P(E) = 1/3

Thus, this option is demonstrating theoretical probability.

This is using experimental results to get the estimated probability.

Actually, assuming coin being fair, both the tail and heads being equally probable, if we take:

E = event of getting head, then as there are two results possible being Tail or Head (assuming only 2 results), and there is one way of getting head in one toss, so we get:
P(E) = 1/2 = 0.5

Thus, this option is demonstrating experimental probability instead of theoretical one.

It is using the data from one experiment. So its experimental probability. Sometimes we can get experimental probability = theoretical probability value, but still, there'd be difference of how you calculated it from the start. Usually, if calculated from experiment, then its experimental probability, and if calculated virtually and based on theories, it is theoretical probability.

Thus, an example of theoretical probability from the considered option is given by: Option 2: A spinner has 8 equal sections numbered 1 to 10. The probability of spinning the number 3 is 1/8

Answer:

33.5 in^3

Step-by-step explanation:

The formula for a cone is (pi)(r^2)(h/3)

Since we need to use 3.14 for pi, we will plug in 3.14 for pi. It should look like this:  (3.14)(r^2)(h/3)

The radius is 2 and the height is 8. Plug in the numbers:

(3.14)(2^2)(8/3)

Simplify:

(3.14)(4)(2.66...)

Multiply:

(12.56)(2.66...) -> 39.4933...

Finally, 39.4933... is rounded to the tenths place:

Step-by-step explanation: 3780 divided by the number of years he paid interest for, (6) gives you 630. If he pays 7% interest, you calculate what number 630 is 7% of (9000.) Therefore he takes out 9000 dollars a year. Meaning that in total, he borrowed 54,000 dollars. (9000 x 6)

The expression 14e - 16 is an algebraic expression, and the factored expression is 2(7e - 8)

The expression is given as:

14e - 16

Express both terms as a product of 2

14e - 16 = 2 * 7e - 2 * 8

Factor out 2 in the expression

14e - 16 = 2 * (7e - 8)

Remove the product sign

14e - 16 = 2(7e - 8)

Hence, the factored expression of 14e - 16 is 2(7e - 8)

The idea here is that we break the cube roots into smaller pieces, so we pull out perfect cubes when factoring.

The sum of the expression is 12 b squared (Root Index 6 Start Root 2 a End Root) or 12b²∛(2a).

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

We have the expression,

3 b squared (Root Index 3 Start Root 54 a End Root) + 3 (Root Index 3 Start Root 2 a b Superscript 6 Baseline End Root).

In numerical form,

3b²∛(54a) + 3∛(2ab⁶)

To find the sum of the above expression:

we simplify the expression,

3b²∛(54a) + 3∛(2ab⁶)

= 3b²∛3³(2a) + 3∛(2a)(b²)³

= 9b²∛(2a) + 3b²∛(2a)

= 12b²∛(2a)

Therefore, the sum is 12b²∛(2a).

We will notice that this is almost the same as 19 solar years of 365.24 days, which is 6939.56 days.

Now, you are referring to the Hebrew Calendar, a 19-year period that consists of 12 years of 12 months plus 7 years of 13 months,

Answer:

WX = 20

FG = 10

Step-by-step explanation:

If EFGHI ~ VUTXW

then:

The only pair of sides that both have measures is EF and VU

EF = 8

VU = 16

VU/EF = 16/8 = 2

Therefore, VUTXW is enlargement of EFGHI by a scale factor of 2.

As HI = 10

⇒ WX = 10 × 2 = 20

As UT = 20

⇒ FG = 20 ÷ 2 = 10

The Algebraic equations (x - 20)² and x² - 20 have an equal value My number is 6.

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result.

Let the number be x.

If I subtract 20 from my number that is x - 20 then square the result that is (x-20)².

And if I square my number that is x² then subtract 20 from the result that is x² - 20.

Both the result are the same then we have

         (x - 20)² = x² - 20

x² - 20x + 100 = x² - 20

  -20x + 100 = -20

                  x = 6

Step-by-step explanation:

A = $4,014.68

A = P + I where

P (principal) = $3,000.00

I (interest) = $1,014.68

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 3,000.00(1 + 0.06/1)^(1)(5)

A = 3,000.00(1 + 0.06)^(5)

A = $4,014.68
