The probability of randomly selecting someone who does not believe that some psychics can help solve murder cases is 46.4%. Hence, the answer is 46.4%.

Given the poll showed that 53.6% of Americans say they believe that some psychics can help solve murder cases.

We are to find the probability of randomly selecting someone who does not believe that some psychics can help solve murder cases.

Let us consider the following events:

Let A be the event that someone believes that some psychics can help solve murder cases and B be the event that someone does not believe that some psychics can help solve murder cases.

Then A and B are complementary events, that is A∩B=∅ (i.e., the events cannot happen at the same time) and A∪B = S (the event space).

Thus we can write P(A) = 53.6% and P(B) = 100% - 53.6% = 46.4%.

Therefore, the probability of randomly selecting someone who does not believe that some psychics can help solve murder cases is 46.4%. Hence, the answer is 46.4%.

An 1 οr perhaps an even integer will be drawn back 75% οf the times frοm the set οf 1, 2, 3 and 4. Thus, Prοbability P(nοt even) is 75%.

Prοbability is the likelihοοd that sοmething will οccur οr the prοbability that sοmething will happen. Prοbability is the measure οf hοw prοbable it is that a cοin will land heads up after being tοssed intο the air.

As prοbabilistic arguments sοmetimes prοduce οutcοmes that appear cοntradictοry οr illοgical, prοbability is usually regarded as amοng the mοst challenging tοpics οf mathematics.

P(1) = 1/4(there is one card with a 1)

P(even) = 2/4 = 1/2 (there are 2 cards with even numbers out of 4)

Therefore,

P( 1 or even) =P(1) + P(even)

= 1/4 + 1/2

= 3/4

To express the answer as a percentage, we can multiply by 100:

P(1 or even) = 3/4 × 100%

Write your answer as a fraction or percentage.

The final answer is that Luis paid $3.58 too much for his purchase ($2.30 - $2.21 = $0.09).

Here's an explanation of the calculations:

To determine the total cost of the purchases, we calculate the price of each item, the total cost of each item, and the total cost of all items combined.

1 gallon of milk at $2.89:

Price: $2.89

2 loaves of bread at $2.19 each with a $0.75 discount:

Price per loaf: $2.19

Total cost of 2 loaves: 2 * $2.19 = $4.38

Total cost with discount: $4.38 - $0.75 = $3.63

2 pounds of ham at $6.89 per pound:

Price per pound: $6.89

Total cost of 2 pounds: 2 * $6.89 = $13.78

1/2 pound of cheese at $8.38 per pound:

Price per pound: $8.38

Total cost of 1/2 pound: 0.5 * $8.38 = $4.19

Total cost before tax: $2.89 + $3.63 + $13.78 + $4.19 = $26.47

Now, we calculate the sales tax at 4% to determine the final cost.

4% of $26.47 = $1.06

Final cost: $26.47 + $1.06 = $27.53

Luis paid $29.83 for the items, which means he paid an extra amount.

Amount paid by Luis: $29.83

Amount he should have paid: $27.53

Amount he paid in excess: $29.83 - $27.53 = $2.30

However, the question asks for the amount paid too much after applying the sales tax, so we need to deduct the tax paid on the excess amount.

Tax paid on the excess amount: $2.30 × (1 - 0.04) = $2.21

The final answer is that Luis paid $3.58 too much for his purchase ($2.30 - $2.21 = $0.09).

Answer:

(a) \(\frac{1}{7}\)

(b) \(\frac{4}{7}\)

(c) \(\frac{5}{7}\)

Step-by-step explanation:

Probability (P) of an event is the likelihood that the event will occur. It is given by;

P = number of favourable outcomes ÷ total number of events in the sample space.

Given letters of cards:

A B C D E F G H J

∴ Total number of events in sample space is actually the number of cards which is 7

If a card is picked at random;

(a) the probability P(F), that it is labelled F is given by;

P(F) = number of favourable outcomes ÷ total number of events in the sample space.

The number of favourable outcomes for picking an F = 1 since there is only one card labelled with F.

∴ P(F) = 1 ÷ 7

=> P(F) = \(\frac{1}{7}\)

(b) the probability P(N), that it is labelled with a letter in her name JADE is given by;

P(N) = P(J) + P(A) + P(D) + P(E)

Where;

P(J) = Probability that it is labelled J

P(A) = Probability that it is labelled A

P(D) = Probability that it is labelled D

P(E) = Probability that it is labelled E

P(J) = \(\frac{1}{7}\)

P(A) = \(\frac{1}{7}\)

P(D) = \(\frac{1}{7}\)

P(E) = \(\frac{1}{7}\)

∴ P(N) = \(\frac{1}{7}\) + \(\frac{1}{7}\) + \(\frac{1}{7}\) + \(\frac{1}{7}\)

∴ P(N) = \(\frac{4}{7}\)

(c) the probability P(S), that it is labelled with a letter that has at least one line of symmetry is;

P(S) = P(A) + P(B) + P(C) + P(D) + P(E) + P(H)

Where;

P(A) = Probability that it is labelled A

P(B) = Probability that it is labelled B

P(C) = Probability that it is labelled C

P(D) = Probability that it is labelled D

P(E) = Probability that it is labelled E

P(H) = Probability that it is labelled H

Cards with letters A, B, C, D, E and H are selected because these letters have at least one line of symmetry. A line of symmetry is a line that cuts an object into two identical halves. Letters A, B, C, D, E and H can each be cut into two identical halves.

P(A) = \(\frac{1}{7}\)

P(B) = \(\frac{1}{7}\)

P(C) = \(\frac{1}{7}\)

P(D) = \(\frac{1}{7}\)

P(E) = \(\frac{1}{7}\)

P(H) = \(\frac{1}{7}\)

∴ P(S) = \(\frac{1}{7}\) + \(\frac{1}{7}\) + \(\frac{1}{7}\) + \(\frac{1}{7}\) + \(\frac{1}{7}\)

∴ P(S) = \(\frac{5}{7}\)

To calculate the approximate volume of concrete that Angel will use, we need to determine the volume of the slab.

The slab is in the shape of a cylinder, and its volume can be calculated using the formula:

V = πr²h

where V is the volume, r is the radius, and h is the height of the cylinder.

From the given information, we know that the slab is 6 inches tall. However, we need to convert the dimensions to the same unit before proceeding with the calculations. Let's convert the dimensions to feet:

Height = 6 inches = 6/12 feet = 0.5 feet

Radius = 2 feet

Now we can substitute the values into the formula to find the volume:

V = π(2²)(0.5)

 = π(4)(0.5)

 = 2π cubic feet

Approximating π to 3.14, we can calculate the volume:

V ≈ 2(3.14)

 ≈ 6.28 cubic feet

Therefore, the approximate volume of concrete that Angel will use is 6.28 cubic feet.

Looking at the given answer choices, the closest value to 6.28 is 10 cubic feet. Therefore, the correct answer is:

The child is paying out cord at a rate of approximately 3.818 feet per second when 165 feet of cord are out.

The Pythagorean theorem can be used to create an equation that relates the distance the kite is from the child's hand to the length of the cord that has been let out:

distance^2 = height^2 + length of cord^2

The derivative of both sides with respect to time can then be used to calculate the rate at which the distance changes:

2 * distance * (rate of change in distance) = 0 + 2 * cord length * (rate of change of length of cord)

When we simplify, we get:

Distance change rate = (cord length / distance) * (rate of change in cord length)

The distance is constant at 105 feet, and the wind is blowing the kite horizontally at 6 feet per second. As a result, the distance is changing at a rate of 6 feet per second.

When 165 feet of cord are out, we are asked to calculate the rate at which the child is paying out cord. We can use the equation we derived to solve for this rate:

rate of change of cord length = (rate of change of distance * distance) / cord length

With the given values, we get:

Cord length change rate = (6 * 105) / 165 = 3.818 feet per second

When 165 feet of cord is out, the child is paying out cord at a rate of approximately 3.818 feet per second.

b) Cluster sampling refers to a sampling design where population is divided into naturally occurring groups and a random sample of clusters is chosen.

The advantages are efficient, easy to perform, and used when the population is widely dispersed. The disadvantages are sampling errors, have lower level of precision, and have the standard error of the estimate.

a) The relevant population for the public relations research department to investigate the initial reactions of heavy soft-drink users to a new all-natural soft drink is heavy soft-drink users. The appropriate sampling design that can be used to investigate the issues is stratified random sampling.

Stratified random sampling is a technique of sampling in which the entire population is divided into subgroups (or strata) based on a particular characteristic that the population shares. Then, simple random sampling is done from each stratum. Stratified random sampling is appropriate because it ensures that every member of the population has an equal chance of being selected.

Moreover, it ensures that every subgroup of the population is adequately represented, and reliable estimates can be made concerning the entire population. The list of all heavy soft-drink users can be the sampling frame.

b) Cluster sampling is a type of sampling design in which the population is divided into naturally occurring groups or clusters, and a random sample of clusters is chosen. The elements within each chosen cluster are then sampled.

The advantages of cluster sampling are:

The disadvantages of cluster sampling are:

A situation where cluster sampling would be appropriate is in investigating the effects of a new medication on various groups of people. In this case, the population can be divided into different clinics, and a random sample of clinics can be selected. Then, all patients who meet the inclusion criteria from the selected clinics can be recruited for the study.

The drilling rig will reach a depth οf -250 feet after 100 hοurs οf cοntinuοus use.

Time is a measure οf the duratiοn between twο events, while distance is the amοunt οf space between twο pοints οr οbjects.

We can start by figuring οut the rate at which the drilling rig is digging. We knοw that it dug a height οf -60 feet in 24 hοurs, sο its rate is:

-60 feet / 24 hοurs = -2.5 feet/hοur

This means that the rig is digging dοwnwards at a rate οf 2.5 feet per hοur.

Tο find οut hοw lοng it will take fοr the rig tο dig tο a depth οf -250 feet, we can use the fοllοwing fοrmula:

time = distance / rate

We want tο dig a distance οf 250 feet (since we're measuring depth belοw grοund level), and οur rate is -2.5 feet per hοur (since we're digging dοwnwards). Plugging these values intο the fοrmula gives:

time = 250 feet / (-2.5 feet/hοur)

Simplifying, we get:

time = -100 hοurs

Since time can't be negative, this tells us that the drilling rig will reach a depth οf -250 feet after 100 hοurs οf cοntinuοus use.

Answer:

\(y = 120 + 0.15x\)

Step-by-step explanation:

Given

\(Additional\ Fee = \$0.15\) per vertical meter

\(y = fee\) per x meter

\(x = vertical\ meter\)

For:

\(x = 3500\) --- \(y = 645\)

Required

Determine the equation that relates y to x

Let the initial fee be represented with m

The equation that relates y to x is:

\(y = Initial\ Fee + Additional\ Fee * Vertical\ Meter\)

This gives

\(y = m + 0.15 * x\)

We need to first solve for m

From the question,

\(x = 3500\) when \(y = 645\)

So:

\(645 = m + 0.15 * 3500\)

\(645 = m + 525\)

Make m the subject

\(m = 645 - 525\)

\(m = 120\)

So, the initial fee is $120

Substitute 120 for m in \(y = m + 0.15 * x\)

\(y = 120 + 0.15 * x\)

\(y = 120 + 0.15x\)

Hence, the required equation is: \(y = 120 + 0.15x\)

41.67% probability that a student has a dog given that they have a cat

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)

In which

P(B|A) is the probability of event B happening, given that A happened.

\(P(A \cap B)\) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: having a cat.

Event B: having a dog.

12 of 27 students have a cat:

This means that \(P(A) = \frac{12}{27}\)

5 students who have a cat and a dog.

This means that \(P(A \cap B) = \frac{5}{27}\)

What is the probability that a student has a dog given that they have a cat?

Answer:

x = 24

Step-by-step explanation:

A triangle has a total of 180 degrees as its inner angle measurement.

If you look at the bigger triangle, it has two out of three angles: 94 and 41.

Since we know the angle has to be 180, we can simply subtract the sum of 94 and 41. We get 45 degrees.

Now that we have that measurement, we look at the smaller triangle. The 45 degrees is shared both by the bigger one and the smaller one. Which gives us two out of three angles for the smaller one.

Again, add 111 and 45 and then subtract the result from 180. We get 24 degrees.
