The value of 3¾ft in yards would be = 1 6/25 yard

A mixed number is the type of number that is made up of three parts such as the whole number, a numerator and a denominator.

To convert to yards;

1 ft = 0.33 yard

3¾ = X yards

make x yards the subject of formula;

X yards = 3¾ × 0.33

X yards = 3.75×0.33

X yards = 1.24 yards

X yards in mixed number= 124/100 = 31/25 = 1 6/25 yard.

Note that the final value which is 124/100 is reduce to the lower figure by dividing through with 4 to arrive at the mixed number 1⁶/25

Now, let's solve it.

Answer:

0.0139 = 1.39% probability that the president will have an IQ of at least 107.5 and that at least one of the other two leaders (vice president and/or secretary of state) will have an IQ of at least 130.

Step-by-step explanation:

To solve this question, we need to use the binomial and the normal probability distributions.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Probability the president will have an IQ of at least 107.5

IQs of adults in a certain country are normally distributed with mean 100 and SD 15, which means that \(\mu = 100, \sigma = 15\)

This probability is 1 subtracted by the p-value of Z when X = 107.5. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{107.5 - 100}{15}\)

\(Z = 0.5\)

\(Z = 0.5\) has a p-value of 0.6915.

1 - 0.6915 = 0.3085

0.3085 probability that the president will have an IQ of at least 107.5.

Probability that at least one of the other two leaders (vice president and/or secretary of state) will have an IQ of at least 130.

First, we find the probability of a single person having an IQ of at least 130, which is 1 subtracted by the p-value of Z when X = 130. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{130 - 100}{15}\)

\(Z = 2\)

\(Z = 2\) has a p-value of 0.9772.

1 - 0.9772 = 0.0228.

Now, we find the probability of at least one person, from a set of 2, having an IQ of at least 130, which is found using the binomial distribution, with p = 0.0228 and n = 2, and we want:

\(P(X \geq 1) = 1 - P(X = 0)\)

In which

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{2,0}.(0.9772)^{2}.(0.0228)^{0} = 0.9549\)

\(P(X \geq 1) = 1 - P(X = 0) = 0.0451\)

0.0451 probability that at least one of the other two leaders (vice president and/or secretary of state) will have an IQ of at least 130.

What is the probability that the president will have an IQ of at least 107.5 and that at least one of the other two leaders (vice president and/or secretary of state) will have an IQ of at least 130?

0.3085 probability that the president will have an IQ of at least 107.5.

0.0451 probability that at least one of the other two leaders (vice president and/or secretary of state) will have an IQ of at least 130.

Independent events, so we multiply the probabilities.

0.3082*0.0451 = 0.0139

0.0139 = 1.39% probability that the president will have an IQ of at least 107.5 and that at least one of the other two leaders (vice president and/or secretary of state) will have an IQ of at least 130.

By using unitary method it can be calculated that

Total cost of 600 pencils = $81.50

Option D is correct

What is unitary method?

Unitary method is the process in which the value of single unit can be calculated from the value of multiple unit and the value of multiple unit can be calculated from the value of single unit. Sometimes Value of single unit can be less than the value of multiple unit. For example - The relation between the cost of a commodity and the quantity of the commodity

Sometimes Value of single unit can be more than the value of multiple unit. For example - The relation between the number of men and the number of days taken by those men to do a certain job.

This is a word problem on unitary method

Cost of 30 pencils = $4

Cost of 1 pencil = $\(\frac{4}{30}\)

Cost of 600 pencils = $\(\frac{4}{30} \times 600\) = $80

Shipping charge for 100 pencils = $0.25

Shipping charge for 1 pencil = $\(\frac{0.25}{100}\)

Shipping charge for 600 pencils = $\(\frac{0.25}{100}\times 600\) = $1.50

Total cost of 600 pencils = $(80 + 1.50) = $81.50

Answer:

Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

Step-by-step explanation:

In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.

Let us consider a random variable, X that follows a normal distribution, N (µ, σ²).

Then Z is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is,

\(Z=\frac{x-\mu}{\sigma}\sim N(0, 1)\)

This, z-score is known as the standardized score.

It is provided that the distribution of finishing time for men (say, X) was approximately normal with mean µ = 242 minutes and standard deviation σ = 29 minutes.

The finishing time for Clay was x = 289 minutes.

Compute Clay's z-score as follows:

\(Z=\frac{x-\mu}{\sigma}\)

   \(=\frac{289-242}{29}\\\\=1.67857143\\\\\approx 1.68\)

Thus, Clay's standardized score is 1.68.

That is, Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

The confidence interval is 0.559 < p < 0.641 and expected value is 0.600

To construct a confidence interval for the true population proportion, we can use the formula:

p ± Z * √((p × (1 - p)) / n)

Where:

p = sample proportion (336/560)

Z = critical value for the desired confidence level

95% confidence = Z-value of approximately 1.96

n = 560

Let's calculate the confidence interval:

p = 336/560 ≈ 0.600

Z ≈ 1.96 (for a 95% confidence level)

n = 560

Plugging these values into the formula:

p ± Z × √((p × (1 - p)) / n)

0.600 ± 1.96 × √((0.600 × (1 - 0.600)) / 560)

0.600 ± 1.96 × √((0.240) / 560)

0.600 ± 1.96 × √(0.0004285714)

0.600 ± 1.96 × 0.020709611

0.600 ± 0.040564459

The confidence interval is:

0.559 < p < 0.641

Therefore, the 95% confidence interval for the true population proportion of adults with children is 0.559 < p < 0.641.

For proportions, the expected value is simply the sample proportion, which is approximately 0.600.

Answer:

a) 3/7

b) $14

Step-by-step explanation:

let the total of his Money be x

on some comics = 3/7 of x

\( \frac{3}{7} \times x \: = \frac{3x}{7} \)

remaining money = x - 3x/7

\(x - \frac{3x}{7} = \frac{7x - 3x}{7} = \frac{4x}{7} \)

on a pack of cards = 1/4 of 4x/7

\( \frac{1}{4} \times \frac{4x}{7} = \frac{4x}{28} = \frac{x}{7} \)

a) left fraction = total money - all spent money

note that; all spent money = money spent on some comics and pack of cards

\(x - ( \frac{3x}{7} + \frac{x}{7} )\)

\(x - ( \frac{3x + x }{7} )\)

\(x - \frac{4x}{7} = \frac{7x - 4x}{7} = \frac{3x}{7} \)

left fraction = 3/7 of the money

b) left money = 3x/7

but since left money is $6

therefore, $6 = 3x/7

multiply both sides by 7

\(6 \times 7 = \frac{3x}{7} \times 7\)

42= 3x

divide both sides by 3

x = 42/3

x = 14

total money = $14

The value of p is 3, the value of q is 5, and the value of r is 70804.

Let a be the first term of the arithmetic series, and d be the common difference.

From the given information, we have:

a = 22

an = 141 - 5 = 136

d = 3

We can use the formula for the nth term of an arithmetic series to find n:

an = a + (n-1)d

136 = 22 + 3(n-1)

114 = 3n - 3

n = 39

Now we can use the formulas for the sum of an arithmetic series to find p, q, and r:

Sn = n/2(2a + (n-1)d)

= 39/2(2(22) + (39-1)3)

= 39/2(44 + 114)

= 39/2(158)

= 3081

So the sum of the first 39 terms of the series is 3081.

We can write this as p(qt - 1), where t is the nth term of the series:

p(qt - 1) = p(a + (n-1)d)(a + (n-1)dq) - p

= p(22 + 3(39-1))(22 + 3(39-1)q) - p

= p(119)(119q) - p

= p(14161q - 1)

We know that this expression equals 3081, so:

p(14161q - 1) = 3081

Dividing both sides by 3081, we get:

p = 3081/(14161q - 1)

Since p, q, and r are integers, we need to find a factorization of 3081 that includes 14161q - 1 as a factor.

We can start by finding the prime factorization of 3081:

3081 = 3 * 1027

= 3 * 7 * 147

= 3 * 7 * 3 * 49

= 3^2 * 7^2 * 7

Now we can try different values of q and see if 14161q - 1 is a factor of 3081.

If q = 1, then 14161q - 1 = 14160, which is not a factor of 3081.

If q = 2, then 14161q - 1 = 28321, which is not a factor of 3081.

If q = 3, then 14161q - 1 = 42482, which is not a factor of 3081.

If q = 4, then 14161q - 1 = 56643, which is not a factor of 3081.

If q = 5, then 14161q - 1 = 70804, which is a factor of 3081.

Therefore, we have:

p = 3081/(14161(5) - 1)

= 3

q = 5

r = 14161q - 1

= 70804

So the value of p is 3, the value of q is 5, and the value of r is 70804.

Answer:

\(l = \boxed{167.}\\w=\boxed{40.}\)

Step-by-step explanation:

Since the perimeter is 414 meters, half of the perimeter is 207 meters. We can write the following equation and solve for h.

\(w + l = 207\\w + (4w + 7) = 207\\5w +7 = 207\\5w = 200\\w = \boxed{40.}\)

Here, we substituted 4w + 7 in place of l as the problem tells us that the length of the pool is 7 meters more than 4 times the width. Solving for the width gave us 40 meters.

Using this information, we can determine that the length of the swimming pool is:

\(4(40) + 7 = 160 + 7 = 167.\)

To double-check that this is correct, we can add twice the length and twice the width to see if it equals the given perimeter:

\(167 + 167 + 40 + 40 = 414.\)

Therefore, your length and width of this swimming pool are:

\(l = \boxed{167.}\\w=\boxed{40.}\)
