1. The probability that Layla gets more than 3 heads is 0.40 (rounded to the nearest hundredth).

P(X>3) = 0.40.Let X represent the number of heads Layla gets on flipping a coin that has a 60% chance of showing heads. She is going to flip the coin five times and we are supposed to find the probability that she gets more than 3 heads. The probability that Layla gets more than 3 heads is P(X>3).

Solution :We are given that the coin has a 60% chance of showing heads each time it is flipped. The probability of getting a head (success) is p = 0.6 and the probability of getting a tail (failure) is q = 0.4. As Layla is going to flip the coin five times, we have n = 5.On each flip, X can either be a head or a tail. Thus, X is a binomial random variable with parameters n = 5 and p = 0.6.P(X>3) can be calculated as:P(X > 3) = P(X = 4) + P(X = 5)P(X = 4) = nCx × p^x × q^(n-x) = 5C4 × 0.6^4 × 0.4^1 = 0.2592P(X = 5) = nCx × p^x × q^(n-x) = 5C5 × 0.6^5 × 0.4^0 = 0.07776P(X > 3) = P(X = 4) + P(X = 5) = 0.2592 + 0.07776 = 0.33696 ≈ 0.40

Let p be the probability that a surgical intervention results in an increased quality of life in a patient, which is given as 60%. Let X be the number of patients out of 20 who have an increased quality of life after undergoing the surgery. We are supposed to find the probability that surgery is effective on 12 patients out of 20.

Solution :Let X be the number of patients out of 20 who have an increased quality of life after undergoing the surgery. Then X is a binomial random variable with parameters n = 20 and p = 0.6.The probability of surgery being effective on exactly 12 patients can be calculated as:P(X = 12) = nCx × p^x × q^(n-x) = 20C12 × 0.6^12 × 0.4^8 = 0.00000078643 (rounded to 11 decimal places)

The probability of surgery being effective on at least 12 patients can be calculated as:P(X ≥ 12) = P(X = 12) + P(X = 13) + ... + P(X = 20)Using a binomial probability distribution table, we can calculate this probability as:P(X ≥ 12) = 0.00000078643 + 0.0000105188 + 0.0000976064 + 0.0007052774 + 0.0038752048 + 0.0163110784 + 0.052553726 + 0.125428942 = 0.1985502502Therefore, the probability that surgery is effective on 12 patients out of 20 is 0.00000078643

Question 2

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

K is equal to 2.632 when the constant term in the expansion of (\(kx-\frac{1}{x^{2} }\))² is 240.

To find the constant term in the expansion of the expression "kx - 1/x^2^6," we can use the binomial theorem. The general term of the binomial expansion is given by:

T(r+1) = C(n, r) x (kx)^(n-r) x (-1/x^2^6)^r

Here, n is the power of the binomial, which is 26 in this case. We are interested in finding the constant term, which means r + 1 = 0. Therefore, r = -1.

Plugging these values into the general term formula, we have:

T(-1+1) = C(26, -1) x (kx)^(26-(-1)) x (-1/x^2^6)^(-1)

         = C(26, -1) x (kx)^27 x (-1)^(-1) x (x^2^6)^(-1)

         = C(26, -1) x (kx)^27 x (-1) x (1/x^2^6)

         = -C(26, -1) x (kx)^27 x ^2^6

The constant term occurs when r = -1, so we need to find C(26, -1). The formula for the binomial coefficient is:

\(C(n, r)\frac{n! }{(r! x (n-r)!)}\)

Plugging in n = 26 and r = -1, we have:

\(C(26, -1) =\frac{26!}{ (-1! x (26-(-1))!)}\)

                \(= \frac{26!}{(-1! x 27!) }\)

Now, we can substitute this value back into the expression for the constant term:

\(T(-1+1) =\frac{ -C(26, -1) x (kx)^27}{x ^ 2 ^ 6}\)

                \(=\frac{-[26! / (-1! x 27!)] x (kx)^27}{ x^2^6}\)

We are given that the constant term is 240, so we can set this expression equal to 240 and solve for k:

\(240 =\frac{-[26! / (-1! x 27!)] x (kx)^27}{x^2^6}\)

Simplifying further:

\(240 =\frac{[26! / (27!)]}{x^2^6 }\)

Now, we can simplify the factorial terms:

\(240 =\frac{(26 / 27) x (kx)^27}{x^2^6 }\)

Cross-multiplying and simplifying:

240 x 27 x x^2^6 = 26 x (kx)^27

Simplifying further:

240 x 27 * x^2^6 = 26k^27 x x^27

Now, we can cancel out the x terms:

240 x 27 = 26k^27

Solving for k:

\(k^27 =\frac{(240 x 27) }{26}\)

\(k =\frac{[(240 x 27)}{26]^(1/27)}\)

Calculating this value, we find:

k ≈ 2.632

Therefore, approximately, k is equal to 2.632.

If the constant term in the expansion of (\(kx-\frac{1}{x^{2} }\))²  is 240, find k. (Simplify your answer. Type an integer or a decimal)

b. To find the probability a customer who ordered pancakes came to thediner late, we need to look at the intersection of the "pancakes" row and the "late" column. This gives us a probability of 0.1, or 10%

c. To determine whether breakfast choice and meal time are independent, we need to see if the probability of one event changes based on the occurrence of the other event. In this case, it seems that breakfast choice and meal time are not independent, as the probability of being late seems to differ based on what breakfast item the customer chose. For example, the probability of being late is higher for customers who ordered pancakes compared to those who ordered cereal. Therefore, the choice of breakfast item appears to be related to the probability of being late, and so breakfast choice and meal time are not independent.

The constant velocity (V) of the car as it decelerates to rest is 2.222 m/s.

Given the following data:

To determine the constant velocity (V) of the car:

First of all, we would calculate the distance traveled by the car within the first 4 seconds of its motion by using the second equation of motion;

\(S = ut + \frac{1}{2} at^2\\\\S=20(4)+\frac{1}{2} \times 2.5 \times 4^2\\\\S=80+20\)

S = 100 meters.

Next, we would calculate the distance traveled after the first 4 seconds of its motion by using the third equation of motion;

Note: Final velocity is equal to zero since the car decelerated to rest.

\(V^2 =u^2 -2aS\\\\0^2 =20^2-2(2.5)S\\\\5S=400\\\\S=\frac{400}{5}\)

S = 80 meters.

Now, we can find the constant velocity (V) of the car:

Time = \(40-4=\) 36 seconds.

Answer:

A. A reflection over the x-axis and a vertical stretch.

Step-by-step explanation:

Let \(h(x) = x^{2}\), to obtain \(k(x) = -4\cdot x^{2}\), we need to use the following two operations:

(i) Vertical stretch

\(g(x) = k\cdot f(x)\), \(k\in \mathbb{R}^{+}\)

(ii) Reflection over the x-axis

\(g(x) = -f(x)\)

Let prove both transformations in \(h(x)\):

Step 1 - Vertical stretch (\(k = 4\))

\(h'(x) = 4\cdot x^{2}\)

Step 2 - Reflection over the x-axis

\(k(x) = -4\cdot x^{2}\)

If the correlation between two variables is .496, 75.4%. much of the variance has not been accounted for.

What is variable?

In the context of statistics and mathematics, a variable is a characteristic or quantity that can vary or take different values.

The correlation coefficient, which ranges from -1 to 1, measures the strength and direction of the linear relationship between two variables. If the correlation between two variables is 0.496, it indicates a moderate positive correlation.

The coefficient of determination, also known as R-squared, represents the proportion of the variance in one variable that can be explained by the other variable. In this case, if the correlation is 0.496, then the coefficient of determination is \((0.496)^2 = 0.246.\)

Therefore, 24.6% of the variance has been accounted for by the correlation, and the remaining 75.4% of the variance has not been accounted for.

Answer:

The length of each hot dog is 0.5000 inches.

Step-by-step explanation:

Total number of hot dogs eaten = 7 000 000 000

Circumference of the earth = 24 860 miles

21.5 times the circumference of the Earth = 21.5 x 24 860 miles

                                                = 534490 miles

But,

1 mile = 5280 feet

So that,

534490 miles = X

X = 5280 x 534490

   = 287707200 feet

Also,

1 feet = 12 inches

Then,

287707200 feet = Y

Y = 12 x 287707200

   = 3452486400 inches

Thus,

the length of each hot dog = \(\frac{3452486400}{7000000000}\)
