given that e1 and e2 have a high spearman correlation, what can we say about the pearson correlation of e1 and e2?

Answer:

D

Step-by-step explanation:

when we have the zeroes, we can build the polynomial by multiplying factors that will turn the functional value to 0 at exactly these points.

f(x) = (x - 3)(x + 6)(x - 1)

we don't need to do the full multiplications to see that the constant term of the polynomial is the result of the multiplication of all 3 constant terms of the factors :

-3 × +6 × -1 = +18

and therefore, D is the correct answer (as it is the only answer option with +18 as constant term).

The first 5 terms of a sequence are shown are called arithematic sequence.

The series where the common difference between any two next words stays constant is known as an arithmetic sequence. Let's review what a sequence is.

A collection of numbers that follow a pattern is called a sequence.

As an illustration, the numbers 1, 6, 11, 16,... are an arithmetic sequence because they follow a pattern in which the preceding term is multiplied by 5 to produce each subsequent number. There are two formulas for arithmetic sequences.

The equation to determine the nth term in an arithmetic sequence

The formula for calculating the sum of an arithmetic sequence's first n terms

The arithmetic sequence formula can be used to discover any term in the arithmetic sequence.

A gap of 2.03 years has a value such that 60% of age disparities are smaller than it.

If the age is expressed as a ratio, such as p:q, then qx and px are taken into account as the age. If you assume that you are x years old now, then n times that number is (xn) years. If you're assuming that x is the current age, then 1/n of that number will equal (x/n) years.

Answer:

y = 120t + 480

Step-by-step explanation:

Answer: A confidence interval is a range of values that is estimated to contain the true value of a population parameter with a certain level of confidence. In the case of the given confidence interval (0.008, 0.094), the interval is estimated to contain the true value of the population parameter with a confidence level of 95%.

To express this confidence interval in the form of p^ - E < p < p^ + E, where p^ is the point estimate of the population parameter and E is the margin of error, we first need to find the point estimate of the population parameter. The point estimate is the midpoint of the confidence interval, which is found by taking the average of the lower and upper bounds of the interval. In the case of the given confidence interval, the point estimate is (0.008 + 0.094) / 2 = 0.051.

The margin of error, E, is found by subtracting the point estimate from the upper and lower bounds of the confidence interval. In the case of the given confidence interval, the margin of error is 0.094 - 0.051 = 0.043 for the upper bound, and 0.051 - 0.008 = 0.043 for the lower bound.

Thus, the given confidence interval can be expressed in the form of p^ - E < p < p^ + E as 0.051 - 0.043 < p < 0.051 + 0.043, which simplifies to 0.008 < p < 0.094. This is the same as the original form of the confidence interval.

Answer:

Elimination is the adding or subtracting of two equations used to solve them.

Step-by-step explanation:

Elimination is the adding or subtracting of two equations used to solve them.

Say you have this equation. [tex]\left \{ {{x + y=2} \atop {-x+y=6}} \right.[/tex]

Notice that the x in both equations are opposites. After adding together we get.

x + y - x + y = 2 + 6

2y = 8

y = 4

x + 4 = 2

x = - 2

(- 2,4)

Say you decide to subtract the equations.

[tex]\left \{ {{x+y=2} \atop {x+2y=8}} \right.[/tex]

x + y - x - 2y = 2 - 8

- y = - 6

y = 6

x + 6 = 2

x = - 4

(- 4, 6)

You can also multiply equations to make it easier to substitute.

[tex]\left \{ {{y+x=4} \atop {-2y+2x=8}} \right.[/tex]

[tex]\left \{ {{2y+2x=8} \atop {-2y+2x=8}} \right.[/tex]

2y + 2x - 2y + 2x = 8 + 8

4x = 16

x = 4

y + 4 = 4

y = 0

For case (a), the person can hike up and down the mountain in 4 different ways. For case (b), the person can hike up and down the mountain in 15 different ways. For case (c), the person can hike up and down the mountain in 12 different ways.

In case (a), the person must take the same trail both ways, so there are only 4 different options available, one for each of the 4 trails.

In case (b), the person can take the same trail both ways if they choose, but they are not required to do so. This means that they have 4 different options for the trail they take on the way up, and then 4 different options for the trail they take on the way down. This results in a total of 4 x 4 = 16 different possibilities.

However, one of these possibilities is the case where the person takes the same trail both ways, which has already been counted in case (a), so we need to subtract this possibility to avoid double counting. This results in a total of 16 - 1 = 15 different possibilities.

In case (c), the person does not want to take the same trail both ways, so they have 4 different options for the trail they take on the way up, and then 3 different options for the trail they take on the way down (since they cannot take the same trail they took on the way up).

$2,060.00 is the entire amount accrued from simple interest on a principal of $2,000.00 at a rate of 3% per year for 1 years, including principal and interest.

Ayden deposits $2000 into a savings account with an annual interest rate of 3%.

To calculate simple interest, multiply the daily interest rate by the principle and the number of days between payments. Consumers that make on-time or early monthly loan payments benefit from simple interest.

A = $2,060.00

I = A - P = $60.00

A is equal to P(1 + rt).

First, convert R percent to r a decimal; for example, R/100 is 3%/100, or 0.03 per year.

A = 2000(1 + (0.03 × 1)) = 2060 \sA = $2,060.00
