The volume of the ark is about 1.44 million cubic feet.

What is unit conversion mean?

A unit conversion expresses the same property as a different unit of measurement. For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.

First, we need to convert the measurements from cubits to inches.

We know that one cubit is equal to six palms and that one palm is equal to 2.5 inches. So, we can convert the measurements of the ark by multiplying the number of cubits by the number of inches per cubit:

Length of ark = 300 cubits x 6 palms/cubit x 2.5 inches/palm = 4500 inches

Width of ark = 50 cubits x 6 palms/cubit x 2.5 inches/palm = 750 inches

Height of ark = 30 cubits x 6 palms/cubit x 2.5 inches/palm = 450 inches

Next, we can find the volume of the ark by multiplying these dimensions together:

Volume of ark = 4500 inches x 750 inches x 450 inches = 1.42 x 10^9 cubic inches

Finally, we can convert cubic inches to cubic feet by dividing by the conversion factor of 1 cubic foot = 12 x 12 x 12 cubic inches.

1.42 x 10^9 cubic inches / (12x12x12 cubic inches/cubic foot) = 1.44 x 10^6 cubic feet

Hence, the volume of the ark is about 1.44 million cubic feet.

The probability that X₁ + X₂ + ........ + X₁₀₀ <60 is 0.9713.

Bernoulli distribution is the probability distribution which is discrete of a random variable X, which has the value 1 if the probability is p and the value is 0 when the probability is 1-p.

We have the measure of z score of a normal distribution as,

z = (X - μ) / σ

After finding the z value. the p value of the corresponding z score can be found.

Binomial distribution is the probability of x random variables or successes on n trials where p is the success of each trial.

In binomial distribution,

μ = [tex]np[/tex] and σ = [tex]\sqrt{np(1-p)}[/tex]

n = 100 and p = 0.5

μ = 100 (0.5) = 50

σ = [tex]\sqrt{50(1-0.5)}[/tex] = 5

We have to find the probability that the sum is less than 60.

Using continuity correction, it is P(X < 59.5).

z = (X - μ) / σ

z = (59.5 - 50) / 5 = 1.9

The p value corresponding to z = 1.9 is 0.9713.

Hence the probability that the X₁ + X₂ + ........ + X₁₀₀ <60 is 0.9713.

Step-by-step explanation:

Hope it helps :)

When you divide a by a percentage of a, you are essentially trying to find out what the percentage of a represents in terms of the value of a.

The percentage of a is represented by the formula (a * x%)/100, where x is the percentage. So if you divide a by (a * x%)/100, you get the following:

a / (a * x%)/100 = 100/x%

This is the equivalent of multiplying a by 100/x%. It's the representation of the percentage in terms of the value of a.

For example:

If a = 100 and x = 20, then a% of a is (10020)/100 = 20. So, a / (a20%) = 100/20 = 5

It means that 20% of 100 is 20 and dividing 100 by 20% of 100 is equal to 5.

Hopefully that helped and didn't make it more confusing.

Answer:

Step-by-step explanation:

a) Percent of already washed cars?

→ ≈ 25.77%

b) Wax job done each week will be?

Hence, these are required answers.

Answer:

a)  25.8%

b)  39

Step-by-step explanation:

Given information:

To find the percent of the total expected cars that have already been washed, divide the number of cars already washed by the average number of cars washed per week:

[tex]\implies \dfrac{67}{260}=0.257692307...=25.8\%\; \sf (nearest\;tenth)[/tex]

To find the number of cars that get a wax job each week, find 15% of 260:

The value of (log √27 + log 8 - log √1000) / log 1.2 is 3/2.

A logarithm is simply the opposite function of the exponentiation.

It is the exponent to which a number or value is raised to get some other number.

That is, if c = aˣ, then we can write it as x =logₐ c.

We have some rules for logarithms which are discussed as below :

log (ab) = log a + log b

log (a/b) = log a - log b

log (aᵇ) = b log a

Using these, let's find the value of the logarithmic expression.

(log √27 + log 8 - log √1000) / log 1.2

= [log [tex](27)^\frac{1}{2}[/tex] + log (2)³ - log [tex](1000)^\frac{1}{2}[/tex]] / log ([tex]\frac{12}{10}[/tex])

= [ [tex]\frac{1}{2}[/tex] log (27) + 3 log (2) - [tex]\frac{1}{2}[/tex] log (1000)] / [log (12) - log (10)]

= [ [tex]\frac{1}{2}[/tex] log (3)³ + 3 log (2) - [tex]\frac{1}{2}[/tex] log (10)³] / [log (3 × 4) - log (10)]

= [ [tex]\frac{3}{2}[/tex] log (3) + 3 log (2) - [tex]\frac{3}{2}[/tex] log (10)] / [log (3) + log (2²) - log (10)]

Using probability the correct option is B)The probability that p is in the interval is equal to the level of confidence for the interval.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject because it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

The probability that p is in the interval is equal to the level of confidence for the interval.

Reason -

There is a 95% probability that the interval between X [lower bound] and Y [upper bound] contains the true value of the population parameter. The statement above is the most common misconception about confidence interval. After the statistical interval is calculated, the interval can only either contain the population parameter or not.

Let S be a subset of R that is closed under multiplication (that is, if a and b are in S, then so is ab). Let Tand Ube disjoint subsets of S whose union is S .Given that the product of any three (not necessarily distinct) elements of T is in T and that the product of any three elements of U is in U, show that at least one of the two subsets T, U is closed under multiplication.

We start out with the assumption that neither T nor U is closed under multiplication and use proof by contradiction to prove that at least one of T or U must be closed under multiplication.

If t1, t2 ,t3 ∈T and u1 ,u2 , u3 ∈U, it is given by the problem that t1⋅t2⋅t3∈T

and u1⋅u2⋅u3∈U. Also, T and U are disjoint subsets of S and therefore, T∩U = ∅ Now let t3=u1⋅u2 and u3=t1⋅t2. These statements are valid because T and U are not closed under multiplication, so the product of u1⋅u2 must not be in the set U and the product of t1⋅t2 must not be in set T.

Then t1⋅t2⋅t3∈T is equivalent to t1⋅t2⋅u1⋅u2∈Tand u1⋅u2⋅u3∈U is equivalent to u1⋅u2⋅t1⋅t2∈U

However, this is a contradiction because these products both are the same —t1⋅t2⋅u1⋅u2— but T∩U= ∅ because Tand U are disjoint. Then the original assumption that "neither T nor U is closed under multiplication" must have been wrong, and at least one of T or U must be closed under multiplication.
