A chairperson, secretary, and treasurer are to be chosen by a six-person committee made up of Alice, Ben, Connie, Dolph, Egbert, and Francisco. Their Calculations are a) 5 × 4 × 3 = 60. (b) 4 × 3 × 2 = 24 (c) 3 × 2 × 4 = 24 (Ben can choose from 3 slots, Francisco has 2 spots remaining to choose from, and there are 4 people available for the final position.)  (d) 3 × 4 × 3 = 36 (Dolph is eligible for three seats, after which there are four more members to pick from.) Part e will be the sum of 2 cases: Case 1 : Dolph is a chairperson. Number of ways = 1 × 5 × 4 = 20. Case 2: Dolph isn't elected. Number of ways for this = 5 × 4 × 3 = 60.

The standard normal distribution is a normal distribution of standardized values called z-scores.

A z-score is measured in units of the standard deviation. If a random variable is normally distributed and follows the parameters mean (mu) and standard deviation (sigma), the z-score is calculated as the difference between the value of the random variable and the mean divided by the standard deviation . The cumulative distribution function (CDF) of a standard normal variable is used to find the fraction of scores that lies between two given values. To determine the fraction of scores, one can use the CDF to find the area under the standard normal distribution curve between the given values.

The probability of eating both poisoned apples if you randomly eat 3 out of the five apples without replacement is 1/10 or 0.1.

To calculate this probability, we use the formula for combinations of n objects taken r at a time, (nCr) which is equal to n!/r!(n-r)!. In this example, n = 5 and r = 3, so the formula reduces to 5!/3!(5-3)! = (5*4*3)/(3*2*1) = 10. This means that there are 10 different combinations of 3 apples, out of the five, that can be chosen. Since only two of the apples are poisoned, the probability of eating both of the poisoned apples is 2/10 or 0.1.

The youngest child is Jade.

The expression that represents Jane's age is 2n.

The oldest child is Jem.

Jade is 12 years old

The equation that represents the sum of ages is 5n - 5 = 55.

Jade's age = n

Jane's age = 2 x n = 2n

Jem's age = 2n - 5

Sum of the ages:

n + 2n + 2n - 5 = 55

5n - 5 = 55

Jade's age can be determined using the above equation:

5n = 55 + 5

5n = 60

n = 60 / 5

n = 12

To determine Jane and Jem's age, substitute for n in the equation that represents their ages.

Jane's age = 2 x 12 = 24

Jem's age = 2(12) - 5

= 24 - 5

Given the above Trigonometric expressions,

1) θ = 35°

2) θ =62°

3) θ = 90-y°

Trigonometric functions are real functions in mathematics that connect an angle of a right-angled triangle to ratios of two side lengths. They are widely utilized in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many more.

There are six expressions of an angle that are often used in trigonometry. Their names and acronyms include

For A)

Sin(55) = cos (θ)

sin (55)= sin(90-θ)

Compare both sides

55 = 90 - θ

θ = 90 - 55

θ = 35°

For B)

Sin(θ) = Cos (28)

angle θ would be  Arc sin (cos (28))

Thus,

θ =  62°

For C)

Cos(y) = sin (θ)

Angle θ = arc sin ( cos (y) )

Thus,

θ = 90 - y

The correct answer is the signs for r and b are the same (+ or ). The slope b and the correlation r don't necessarily have the same values, but they always share the same sign.

The idea employed in the issue is

1.Correlation

2.Regression

Correlation: Correlation analysis is used to gauge how strongly two variables are related. The symbol for the correlation coefficient is r.

Shape: Whether the data points follow a linear pattern or some other complex curves is indicated by the association's form. If it seems that a line would adequately summarise the overall trend in the data, then do so. The relationship between the two variables is then linear.

The appropriate statement can be found below:

The determination of the standard deviation between the two variables influences how a least-squares linear regression function slopes, and in a similar way, how the sample correlation coefficients are interpreted.

By examining the sign of the regression slope and the correlation coefficient, which depend on the standard deviation between the two variables, the proper conclusion can be drawn.

Answer:

So, the solution is x = -3 and y = 4. This means that the two lines intersect at the point (-3, 4)

Step-by-step explanation:

The given equations represent two lines in a two-dimensional plane. To find the solution for the values of x and y that satisfy both equations, we can use the method of substitution or elimination.

Using substitution, we can solve for x or y in one of the equations and substitute the result into the other equation. Let's solve for y in the second equation:

x + y = 1

y = -x + 1

Now, substitute this expression for y into the first equation:

-x + (-x + 1) = 7

-2x + 1 = 7

-2x = 6

x = -3

Finally, we can use the expression for y that we derived earlier to find y:

y = -x + 1 = -(-3) + 1 = 4

The simplified form of the expression is (x - 2) / (x - 3).

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expression is (1 - [tex]\frac{2}{x}[/tex] ) / (1 - [tex]\frac{3}{x}[/tex] ).

Cross multiplying both the denominator and numerator of the expression,

1 - [tex]\frac{2}{x}[/tex] = (x - 2) / x and 1 - [tex]\frac{3}{x}[/tex] = (x - 3) / x

(1 - [tex]\frac{2}{x}[/tex] ) / (1 - [tex]\frac{3}{x}[/tex] ) = [(x - 2) / x] / [(x - 3) / x]
