Let X1, X2, … X100 all be independent Bernoulli variables, which take a value of 1 with probability 0.5. Estimate the probability that X1 + X2 +...+ X100 < 60
The probability that X₁ + X₂ + ........ + X₁₀₀ <60 is 0.9713.
What is Bernoulli Distribution?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.

Let f(x) = |x| + 5
The graph of f(x) is transformed into the graph of g(x) by a translation of 4 units right
and a translation of 3 units down.
What is the equation for g(x)?
When a graph is translated to the right by a units, the x-coordinate of each point on the graph increases by a units. So the equation of the transformed function will have x - a in it.
When a graph is translated down by b units, the y-coordinate of each point on the graph decreases by b units. So the equation of the transformed function will have y - b in it.
Given f(x) = |x| + 5 and the graph of f(x) is transformed into the graph of g(x) by a translation of 4 units right and a translation of 3 units down, the equation of the transformed function g(x) will be:
g(x) = f(x - 4) - 3
This is because the x-coordinate increases by 4 units and the y-coordinate decreases by 3 units.
So the equation of g(x) is:
g(x) = |x-4| + 5 - 3
g(x) = |x-4| + 2
This function g(x) will have the same shape as f(x) but shifted 4 units to the right and 3 units down.
Answer:
This function g(x) will have the same shape as f(x) but shifted 4 units to the right and 3 units down.

B) What is the probability that a randomly chosen child has a height of more than 48.8 inches? (Round to 3 decimal places.)
The likelihood that a randomly selected youngster is under 49 inches tall is 0.989
The likelihood that a randomly selected child would be taller than 48.8 inches is 0.875.
Let the X represent a ten-year-old child's height measurements.
As a result, with a mean of 56.2 inches and a standard deviation of 3.3 inches, X follows the normal distribution.
A) We need to calculate the likelihood that a youngster selected at random is under 63.75 inches tall.
Specifically,
P(X < 63.75)
The Z score calculation gives us
Z = (X - μ)/σ
where mean is and standard deviation is.
Z = (63.75 - 56.2)/3.3
Z = 2.288 as a result.
According to the z distribution table, the value is around 0.989
B) Similar to this, the Z score formula gives us
Z = (X - μ)/σ
where μ mean is and σ standard deviation is.
Therefore, we must determine the likelihood that a child picked at random will be taller than 60 inches.
Z = (60 - 56.2)/3.3
Z = 1.1515
The number is around 0.875 according to Z score.

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.

Step-by-step explanation:
area = length x width
1/4 = 5/8w
isolate 'w' by dividing each side by 5/8
remember, when dividing fractions you must multiply by the reciprocal
1/4 x 8/5 = w
8/20 = w
simplify:
2/5 = w
Which of the following types of words must be capitalized? (5 points) a A government position when it comes before a specific name b Time of year when mentioned in a general way c The last word in a narrative sentence d Every word in a book title
The types of words must be capitalized is
A) A government position when it comes before a specific name
What is Word Capitalization?In writing systems with a case distinction, capitalization (American English) or capitalisation (British English) refers to writing a word with its initial letter as a capital letter (uppercase letter) and the other characters in lower case. The phrase could also be used to describe the choice of text case.
Given:
In English, the initial word of a phrase and all proper nouns are written in capital letters (words that name a specific person, place, organization, or thing).
The initial word in a quotation and the first word following a colon may occasionally both need to be capitalized.
So, the types word can be capitalized is a government position when it comes before a specific name like President Obama.

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.

A population proportion is 0.30. A random sample of size 150 will be taken and the sample proportion p will be used to estimate
the population proportion. Use the z-table..
Round your answers to four decimal places.
a. What is the probability that the sample proportion will be within ±0.03 of the population proportion?
b. What is the probability that the sample proportion will be within ±0.08 of the population proportion?
There is a 0.48 percent chance that the sample proportion will be within 0.03 of the population proportion.
How do you find the probability of a sample proportion for a population proportion?There is a 0.48 percent chance that the sample proportion will be within 0.03 of the population proportion. A sample of 500 people yields a population proportion of 1.00. A sample proportion has a 0.96 probability of being within 0.03 of the population proportion.
The number of successes (X) of the entire population (N) divided by the population size (N) gives the population percentage (p): p = X/N. The sample proportion (p) is calculated by dividing the number of successes observed in the sample (x) by the sample size (n): p = x/n. The sample proportion is determined in this way.
Event E in this puzzle equals game A. The likelihood of losing a game is 0.7 as a result.
