a) Pr(Y > 1) ≈ 0.8944. b) Pr(0 ≤ Y ≤ 5) ≈ 0.7580. c) Pr(Y ≤ 1.0) ≈ 0.6827. Explanation provided for each probability calculation.

a) If Y is distributed N(6,16), the probability of Y being greater than 1 can be found by calculating the z-score and referring to the standard normal distribution table.

Using the formula z = (Y - μ) / σ, where Y is the value of interest, μ is the mean, and σ is the standard deviation, we get z = (1 - 6) / √16 = -5/4.

By looking up the corresponding z-score in the standard normal distribution table, we find that Pr(Y > 1) is approximately 0.8944.

b) If Y is distributed N(2,25), the probability of Y being between 0 and 5 can be found by calculating the z-scores for both values and then finding the area between them in the standard normal distribution.

The z-score for 0 is (0 - 2) / √25 = -2/5, and the z-score for 5 is (5 - 2) / √25 = 3/5. By subtracting the cumulative probability of -2/5 from the cumulative probability of 3/5, we find that Pr(0 ≤ Y ≤ 5) is approximately 0.7580.

c) If Y is distributed χ^2(1), the probability of Y being less than or equal to 1.0 can be found by referring to the chi-square distribution table with 1 degree of freedom.

The probability Pr(Y ≤ 1.0) is approximately 0.6827.

Answer:

4:9

Step-by-step explanation:

You already know the number of minutes he lifted weights which is 20 minutes, based on the question. Now, we just have to find the total number of minutes to his entire workout.

Total minutes to entire workout = 20 + 25

                                                     = 45 minutes

Number of minutes he lifted weights : Total number of minutes of his workout

20                                                          : 45

4                                                            : 9

(You can further simplify the ratio by dividing 20 and 45 by 5)  

1+C is [-4 -4].

(i) AC = [13 -32 -40]
(ii) A + B = [-5.1 2.7 -2.8]
(iii) AB = [-13.3 10.3 -10.3]
(iv) 4A + 4B = [-20.4 10.8 -11.2]
(v) A + C = [-11 -9 -10]
(vi) 1 + C = [ -4 -4]
(vii) CA = [6 11 8]
(viii) BA = [-6.3 9.9 -9.9]
(ix) B + A = [-5.1 2.7 -2.8]
(x) 4(A + B) = [-20.4 10.8 -11.2]
(a) MATLAB may refuse to do some calculations if they are not mathematically valid. For example, the product of two matrices (AB) must have the same number of columns in the first matrix as the number of rows in the second matrix.
(b) Yes, 4(A + B) = 4A + 4B.
(c) No, AB ≠ BA.
(d) Adding a scalar to a matrix adds the scalar to each element of the matrix. In this case, 1+C is [-4 -4].
(e) Yes, A + B = B + A.

The expected number of coins that are heads at the end after Jennifer has tossed 64 fair coins and those that landed on tails were tossed again is 32. the expected number of coins that are heads at the end is 48.

Here is a detailed explanation:Jennifer tosses 64 coins, and each coin has an equal chance of landing on either heads or tails. Thus, the probability that any one coin lands on heads is 0.5, and the probability that it lands on tails is also 0.5.When Jennifer tosses the 64 coins, some of them will land on tails.

Those coins will be tossed again. However, the probability of getting heads or tails for these coins is still 0.5 since the coins are fair.Therefore, the probability that a coin that has already been tossed and landed on tails to land on heads the second time is also 0.5.

The same applies to the third toss. The probability that a coin will land on heads or tails is 0.5.The total number of coins that land on tails during the first toss is given by

64*0.5 = 32.

Since these coins are tossed again, the expected number of coins that land on tails for the second toss is given by

32*0.5 = 16.

The remaining coins that landed on heads during the first toss are not affected. Thus, the expected number of coins that landed on heads during the first toss is

64 - 32 = 32.

The total number of coins that landed on heads during the first toss is given by 32.

Adding the expected number of coins that land on heads during the second toss (16),

the expected number of coins that land on heads is

32 + 16 = 48.

Answer:

x ≈ - 2.193 , x ≈ 3.193

Step-by-step explanation:

x² - x - 7 = 0 ( add 7 to both sides )

x² - x = 7

to complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 0.5)x + 0.25 = 7 + 0.25

(x - 0.5)² = 7.25 ( take square root of both sides )

x - 0.5 = ± \(\sqrt{7.25}\) ≈ ± 2.693 ( add 0.5 to both sides )

x = 0.5 ± 2.693

then

x = 0.5 - 2.693 = - 2.193

x = 0.5 + 2.693 = 3.193

The probability that the couple will have more than 2 girls is 1/2.

Here, we are given that a couple is planning to have 3 children.

Let us list down all the possible combination of outcomes-

GGG, GGB, GBB, BBB

Here G stands for a girl and B for a boy.

Thus, there are a total of 4 outcomes. We need to find the probability that the number of girls is greater than or equal to 2.

Out of the listed outcomes, 2 combinations- GGG and GGB have number of girls ≥ 2.

We know that probability = Number of favorable outcomes/ total number of outcomes

P(x ≥ 2) = 2/4

= 1/2

Thus, the probability that the couple will have more than 2 girls is 1/2.

A simple linear regression model only includes one independent variable, while a multiple linear regression model includes two or more independent variables. The purpose of both models is to examine the relationship between the dependent variable and the independent variable(s) and to make predictions based on that relationship.

If the same dependent variable and independent variable(s) were used in both the simple and multiple linear regression tests, then it is possible that the results could be different. The multiple linear regression model may provide a more accurate prediction of the dependent variable since it takes into account multiple independent variables. Overall, without more information about the data and the specific models used, it is difficult to determine whether the results of the simple and multiple linear regression tests were different or not.

Perimeter is a linear dimension, measured in length units. The perimeter of the new garden will be 4/5 the perimeter of the old garden.

The estimated derivatives are g'(1) ≈ -35.000 and f'(2) ≈ -3.000.

To estimate the derivative of g(t) at t=1, we can use the definition of the derivative as the limit of the difference quotient:
g'(1) = lim(h→0) [(g(1+h) - g(1))/h]
= lim(h→0) [(7/(1+h)^5 - 7)/h]
= lim(h→0) [(7 - 7(1+h)^5)/h(1+h)^5]
= lim(h→0) [(-35h - 70h^2 - 70h^3 - 35h^4 - 7h^5)/h(1+h)^5]
= lim(h→0) [(-35 - 140h - 210h^2 - 140h^3 - 35h^4)/(1+h)^5]
= -35
So, g'(1) ≈ -35.000

Similarly, to estimate the derivative of f(x) at x=2, we can use the definition of the derivative as the limit of the difference quotient:
f'(2) = lim(h→0) [(f(2+h) - f(2))/h]
= lim(h→0) [((4 - 3(2+h)) - (4 - 3(2)))/h]
= lim(h→0) [(-3h)/h]
= lim(h→0) [-3]
= -3
So, f'(2) ≈ -3.000

The first five terms of the sequence are a₁ = 3, a₂ = 11, a₃ = 35, a₄ = 107 and a₅ = 323

A recursive formula, also known as a recurrence relation, is a formula that defines a sequence in terms of its previous terms. It is a way of defining a sequence recursively, by specifying the relationship between the current term and the previous terms of the sequence.

To find the first five terms of the sequence, we can apply the recursive formula

a₁ = 3

aₙ = 3aₙ₋₁ + 2 for n > 1

Using this formula, we can find each term in the sequence by substituting the previous term into the formula.

a₂ = 3a₁ + 2 = 3(3) + 2 = 11

a₃ = 3a₂ + 2 = 3(11) + 2 = 35

a₄ = 3a₃ + 2 = 3(35) + 2 = 107

a₅ = 3a₄ + 2 = 3(107) + 2 = 323

The probability that a current measurement is less than 10 milliamperes can be found by computing the cumulative distribution function (CDF) of the random variable x at 10 milliamperes.

The CDF of a continuous random variable x is defined as the probability that x is less than or equal to a given value.

In this case, we want to find the CDF of x at 10 milliamperes, which we can write as F(10), where:

F(10) = P(X <= 10) = ∫_0¹⁰ f(x) dx

Using the probability density function f(x) given in the problem, we can evaluate the integral to find the CDF:

F(10) = ∫_0¹⁰ 0.05 dx = 0.5

So the probability that a current measurement is less than 10 milliamperes is 0.5. This means that half of the possible current measurements will be less than 10 milliamperes, and half will be greater than 10 milliamperes.

The null and alternative hypotheses are:

H0: β1 = 0 (The slope is not significant.)

H1: β1 ≠ 0 (The slope is significant.)

Here,β1=0.0943seβ1=0.107α=0.05

Test the slope significance and find the t-test statistic.

We need to find the t-test statistic so that we can compare it with the t-distribution, whose distributional properties we know, to determine if we can reject or fail to reject the null hypothesis.t-test statistic is calculated by dividing the value of β1 by its standard error (seβ1) and taking the absolute value of this quotient.

t-test statistic = | β1/seβ1 | = |0.0943/0.107| = 0.881

The degrees of freedom (df) associated with this t-test are df = n - 2, where n is the sample size for the explanatory variable x.

In this problem, the decision rule and conclusion are as follows:

Decision Rule: Reject the null hypothesis if |t-test statistic| > tc where tc is the critical value obtained from the t-distribution with df degrees of freedom and a significance level of α/2 in each tail.

Conclusion: The slope is not significant if we fail to reject the null hypothesis, but the slope is significant if we reject the null hypothesis. Since the t-test statistic (0.881) is less than the critical value (1.987), we fail to reject the null hypothesis. Therefore, we conclude that the slope is not significant.
