If I offered to bet you a tasty beverage that I could toss a coin ten times and produce a sequence of heads and tails that has less than a 1 in 1000 chance of occurring, your chances of winning the bet is 0.99902.

If the coin is fair, the likelihood of getting a head or a tail in a coin toss is equal.

P(H) = P(T)

P(H) = 0.5

The coin has now been tossed ten times.

The probability of receiving 10 heads or 10 tails is binomial and equal.

P(X=10) = \(^{10}\textrm{C}_{10}\) · (0.5)¹⁰ · (1-0.5)⁰

P(X=10) = \(\frac{10!}{10!(10-10)!}\) · 0.00098 · (0.5)⁰

P(X=10) = \(\frac{10!}{10!0!}\) · 0.00098 · 1

P(X=10) = 0.00098

P(X=10) = 0.00098

You win the bet if the dealer does not now deliver a string of 10 heads.

As a result, your chances of winning the wager are 1 - 0.00098 = 0.99902. This is quite high, thus you ought to accept the wager.

Answer:

all 3 options are true : A, B, C

Step-by-step explanation:

warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.

they say that A and C are correct.

but I am going to show you that if A and C are correct, then also B must be correct.

therefore, my given answer above is the actual correct answer (no matter what the test systems say).

originally the information about the alignment of the point F in relation to point E was missing.

therefore, I considered both options :

1. F is on the same vertical line as E.

2. F is not on the same vertical line as E.

because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :

the vertical line of EF is like a mirror between the left and the right half of the picture.

A is mirrored across the vertical line resulting in B. and vice versa.

the same for C and D.

this leads to the effect that all 3 given congruence relationships are true.

if we consider assumption 2, none of the 3 answer options could be true.

but if the assumptions are true, then all 3 options have to be true.

now, for the "why" :

remember what congruence means :

both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.

for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.

so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.

therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.

but do you notice something ?

both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.

now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.

therefore, AC must be equal to BD.

and that means that AC is congruent to BD.

because lines have no other congruent criteria - only the lengths must be identical.

Answer:

(1) TRUE.

(2) FALSE.

(3) FALSE.

(4) TRUE.

(5) FALSE.

Step-by-step explanation:

(1) \(\sqrt{32} = 2^{\frac{5}{2} }\)

\(2^{\frac{5}{2} } = (\sqrt{2} )^5 = (\sqrt{2} \ \times \ \sqrt{2} \ \times \ \sqrt{2} \ \times \ \sqrt{2} \ \times \ \sqrt{2}) = 4\sqrt{2}\\\\\sqrt{32} = \sqrt{16 \ \times \ 2}\ = \ \sqrt{16} \ \times \ \sqrt{2} \ = \ 4\sqrt{2}\)

Thus, the equation is TRUE.

(2) \(16^{\frac{3}{8} } = 8^2\)

\(16^{\frac{3}{8} } =(2^4)^{\frac{3}{8} } = 2^\frac{3}{2} }= (\sqrt{2} )^3 = (\sqrt{2} \ \times \ \sqrt{2} \ \times \ \sqrt{2}) = 2\sqrt{2} \\\\8^2 = 64\)

Thus, the equation is FALSE.

(3) \(4^{\frac{1}{2} } = \sqrt[4]{64}\)

\(4^{\frac{1}{2} }= \sqrt{4} = 2\\\\\sqrt[4]{64} = (64)^{\frac{1}{4} } = (2^6)^{\frac{1}{4} }= 2^{\frac{6}{4} } = 2^{\frac{3}{2} }=(\sqrt{2} )^3 = (\sqrt{2} \times \sqrt{2} \times \sqrt{2} ) = 2\sqrt{2}\)

Thus, the equation is FALSE.

(4) \(2^8 = (\sqrt[3]{16} )^6\)

\(2^8 = 256\\\\ (\sqrt[3]{16} )^6 = (16)^{\frac{6}{3} } = (2^4)^{\frac{6}{3} } = (2)^{\frac{24}{3} } = 2^8 = 256\)

Thus, the equation is TRUE.

(5) \((\sqrt{64} )^{\frac{1}{3} } = 8^{\frac{1}{6} }\\\\\)

\(8^{\frac{1}{6} } = (2^3)^{\frac{1}{6} } = 2^{\frac{3}{6} } = 2^{\frac{1}{2} } = \sqrt{2} \\\\(\sqrt{64} )^{\frac{1}{3} } = (2^6)^{\frac{1}{3} } = 2^{\frac{6}{3} } = 2^2 = 4\)

Thus, the equation is FALSE.

The letter used to represent Pearson's product-moment correlation coefficient is "r".

This coefficient measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no linear correlation.

To calculate Pearson's correlation coefficient, we first standardize the variables by subtracting their means and dividing by their standard deviations. Then, we calculate the product of the standardized values for each pair of corresponding data points. The sum of these products is divided by the product of the standard deviations of the two variables. The resulting value is the correlation coefficient "r".

The required rate of return (or minimum acceptable rate of return) is 20 percent. If the net cash flows are $15,000 per year for ten years, the total cash flow is $150,000. The project's cost is $47,500. We can now apply the net present value formula to determine whether or not the project is feasible.

Net Present Value (NPV) = Cash flow / (1 + r)^n - Cost Where, r is the discount rate, n is the number of years, and Cost is the initial outlay.

Net Present Value = 150000 / (1 + 0.20)^10 - 47500

Net Present Value = $67,482.22

Since the NPV is positive, the project is feasible. When calculating net present value, it's important to remember that a positive NPV implies that the project is expected to generate a return that exceeds the cost of capital, whereas a negative NPV indicates that the project is expected to generate a return that is less than the cost of capital, and as a result, it should be avoided.

Answer:

The measure of the missing angle is 61

Step-by-step explanation:

Using the Consecutive Interior Angles theorem, you know that the angles are supplementary (meaning both angles combine to a 180* plane). Using that logic, you may subtract 119 from 180, and you get a 61* angle.

Based on the given information, Carl's car wash takes a constant time of 4.5 minutes in its automated car wash cycle. Autos arrive following a Poisson distribution at the rate of 10 per hour. Using this information, Carl can calculate the expected time it would take to wash a car.

The first step is to calculate the average time between car arrivals, which is equal to 60 minutes divided by the arrival rate of 10 cars per hour, giving an average time of 6 minutes per car. Since the wash cycle time is constant at 4.5 minutes, Carl can add these two values together to get an expected wash time of 10.5 minutes per car.

However, it's important to note that this is just an expected time, and there may be variations due to factors such as queue length, equipment malfunctions, or other unforeseen circumstances. Therefore, Carl should regularly monitor his car wash operation and make adjustments as necessary to ensure efficient and consistent service.

In summary, Carl's car wash takes a constant time of 4.5 minutes in its automated car wash cycle, and with autos arriving at a rate of 10 per hour, the expected time it would take to wash a car is 10.5 minutes.

Answer:

Sarah bought 7 coach tickets and 4 first class tickets.

Step-by-step explanation:

From the information provided, you can write the following equations:

x+y=11 (1)

240x+1100y=6080 (2), where:

x is the number of coach tickets

y is the number of first class tickets

In order to find the value of x and y, first you have to solve for x in (1):

x=11-y (3)

Now, you have to replace (3) in (2) and solve for y:

240(11-y)+1100y=6080

2640-240y+1100y=6080

860y=6080-2640

860y=3440

y=3440/860

y=4

Finally, you can replace the value of y in (3) to find the value of x:

x=11-y

x=11-4

x=7

According to this, the answer is that Sarah bought 7 coach tickets and 4 first class tickets.

There is a 65% chance that X is above approximately 96.147.

To solve these probability questions related to a normal distribution, we can use the standard normal distribution and convert the given values to Z-scores. The Z-score measures the number of standard deviations a given value is away from the mean.

a. Less than 95:

First, we calculate the Z-score for 95 using the formula:

Z = (X - µ) / σ

Z = (95 - 100) / 10

Z = -0.5

Next, we can look up the corresponding cumulative probability for the Z-score -0.5 in the standard normal distribution table. The table gives us the probability to the left of the Z-score.

Using the table or a calculator, we find that the cumulative probability for Z = -0.5 is approximately 0.3085.

Therefore, the probability that X is less than 95 is approximately 0.3085.

b. Between 95 and 97.5:

We calculate the Z-scores for both values:

Z1 = (95 - 100) / 10 = -0.5

Z2 = (97.5 - 100) / 10 = -0.25

Next, we find the cumulative probabilities for these Z-scores:

P(Z < -0.5) ≈ 0.3085

P(Z < -0.25) ≈ 0.4013

To find the probability between 95 and 97.5, we subtract the cumulative probability of -0.5 from the cumulative probability of -0.25:

P(95 < X < 97.5) = P(Z < -0.25) - P(Z < -0.5)

≈ 0.4013 - 0.3085

≈ 0.0928

Therefore, the probability that X is between 95 and 97.5 is approximately 0.0928.

c. Above 102.2:

We calculate the Z-score for 102.2:

Z = (102.2 - 100) / 10

Z = 0.22

To find the probability above 102.2, we subtract the cumulative probability of the Z-score 0.22 from 1 (since the cumulative probability is the probability to the left of the Z-score):

P(X > 102.2) = 1 - P(Z < 0.22)

Using the table or a calculator, we find that the cumulative probability for Z = 0.22 is approximately 0.5871.

P(X > 102.2) = 1 - 0.5871

≈ 0.4129

Therefore, the probability that X is above 102.2 is approximately 0.4129.

d. There is a 65% chance that X is above what value?

To find the value above which there is a 65% chance, we need to find the corresponding Z-score.

We know that 65% of the area under the normal curve lies to the left of this Z-score, which means that the remaining 35% is to the right.

Using the standard normal distribution table or a calculator, we find the Z-score that corresponds to a cumulative probability of 0.35. Let's call this Zc.

Zc ≈ -0.3853

Now, we can solve for X using the formula:

Zc = (X - µ) / σ

Plugging in the given values:

-0.3853 = (X - 100) / 10

Solving for X:

-0.3853× 10 = X - 100

-3.853 = X - 100

X = -3.853 + 100

X ≈ 96.147

Therefore, there is a 65% chance that X is above approximately 96.147.

The process of finding the derivative of a function is called differentiation.

Differentiation is a fundamental concept in calculus that involves determining the rate at which a function changes with respect to its independent variable. It allows us to analyze the behavior of functions, such as finding slopes of curves, identifying critical points, and understanding the shape of graphs.

The derivative of a function represents the instantaneous rate of change of the function at any given point. It provides information about the slope of the tangent line to the graph of the function at a specific point.

The notation used to represent the derivative of a function f(x) with respect to x is f'(x) or dy/dx. The derivative can be interpreted as the limit of the difference quotient as the interval approaches zero, representing the infinitesimal change in the function.

By applying differentiation techniques, such as the power rule, product rule, chain rule, and others, we can find the derivative of a wide range of functions. Differentiation is a powerful tool used in various areas of mathematics, physics, engineering, economics, and other fields to analyze and solve problems involving rates of change.

The value of the yakubu and bello business is N80,000.

Let's start by determining the original value of Yakubu and Bello's shares in the business before the sale took place.

The ratio of their shares is given as 3:5, which means Yakubu owns 3 parts and Bello owns 5 parts out of a total of 3+5 = 8 parts.

Now, let's assume the value of the business is represented by "V" (to be determined).

Since Yakubu later sold 3/4 of his share to Bello, this means he sold 3/4 * 3 = 9/4 parts of the business to Bello.

The value of 9/4 parts of the business is N180,000, so we can set up the following equation:

(9/4) * V = N180,000

To solve for V, we multiply both sides of the equation by 4/9:

V = (4/9) * N180,000

V = N80,000

Therefore, the value of the business is N80,000.
