Answer:

(1, -1)

Step-by-step explanation:

we isolate y in the first equation

2x+y=1

-2x.  -2x

y=1-2x

and now we fill y into second equation

4x-2(1-2x)=6

4x-2+4x=6

8x-2=6

   +2 +2

8x=8

/8 /8

x=1

and now to find y we insert x

2(1)+y=1

2+y=1

-2.   -2

y= -1

hopes this helps

The answer is: a. Yes, the forecast fails the bias test.

To determine whether the forecast fails the bias test, we need to compare the Average Error (AE) with zero.

If the AE is significantly different from zero, it indicates the presence of bias in the forecast. If the AE is close to zero, it suggests that the forecast is unbiased.

In this case, the Average Error (AE) is -2.0, which means that, on average, the forecast is 2.0 units lower than the actual values. Since the AE is not zero, we can conclude that there is a bias in the forecast.

Therefore, the answer is:

a. Yes, the forecast fails the bias test.

By saying "paying the same rate"

I believe you want to know for example when two people are buying a product how to know if they are paying the same amount.

If so then there are a couple of factors at play.

First of all you need to identify the GDP of the product and the amount of tax/VAT which if calculated properly may help you tell if they are paying the same amount or not.

Answer:

C

Step-by-step explanation:

The slope is 1400. And the y intercept is 5000 because when x=0 y=5000. And if you multiply 1400 by 4 and then add 5000 you get 10,600 lbs for the weight at 4 weeks.

The slope is 1400 and the y-intercept is 5000 of the linear equation which is the correct answer would be option (C) y = 1400x + 5000; 10,600 lbs.

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

We have to determine the slope and y-intercept of the linear equation that models this data,

Week       Weight (lbs)

0                 5000

1                 6400

2                 7800

3                 9200

Slope  = (7800 - 6400)/(2 - 1) = 1400

There is a 1400 slope.

And since y=5000 for x=0, the y-intercept is 5000.

So the equation of a baby whale’s weight at 4 weeks is y = 1400x + 5000

Hence, the correct answer would be option (C)

Step-by-step explanation:

The average rate change of over the interval [-1,1] is 2.

What is an interval?

In mathematics, an interval is expressed in numerical terms. All the numbers between two specific numbers are referred to as an interval. All actual numbers between those two are included in this range.

Given points on the graph is

x   -2     -1     0     1        

y   -4     -3     -1     3

The average rate of change of a function is defined by the expression over the interval a ≤ x ≤ b,

Average rate of change = [f(b) - f(a)]/(b - a)

Here a = -1, b = 1, f(a) = -3, and f(b) = 3

The average rate is (3 - (-3))/ (1 - (-1)) = 2

(a) Rejection region: Reject H0 if the calculated test statistic falls below the lower critical value or above the upper critical value at α/2 = 0.025.

(b) Rejection region: Reject H0 if the calculated test statistic exceeds the upper critical value at α = 0.025.

(c) Rejection region: Reject H0 if the calculated test statistic falls below the lower critical value at α = 0.01.

We have,

To determine the rejection region for the Wilcoxon signed rank test, we need to consider the sample size (n), the alternative hypothesis (Ha), and the significance level (α).

The rejection region consists of the critical values that, if exceeded, would lead to the rejection of the null hypothesis (H0).

Here are the rejection regions for each set of hypotheses:

(a)

H0: M = 0 versus Ha: M ≠ 0, n = 19, α = 0.05:

The rejection region consists of the lower and upper critical values of the Wilcoxon signed rank test at significance level α/2 = 0.05/2 = 0.025.

(b)

H0: M ≤ 0 versus Ha: M > 0, n = 8, α = 0.025:

The rejection region consists of the upper critical value of the Wilcoxon signed rank test at significance level α = 0.025.

(c)

H0: M ≥ 0 versus Ha: M < 0, n = 14, α = 0.01:

The rejection region consists of the lower critical value of the Wilcoxon signed rank test at significance level α = 0.01.

Thus,

(a) Rejection region: Reject H0 if the calculated test statistic falls below the lower critical value or above the upper critical value at α/2 = 0.025.

(b) Rejection region: Reject H0 if the calculated test statistic exceeds the upper critical value at α = 0.025.

(c) Rejection region: Reject H0 if the calculated test statistic falls below the lower critical value at α = 0.01.

If Miller is going to install baseboard around the perimeter of her room's rectangular floor, s.  it will cost Miller $19.20 to purchase baseboard for her room, assuming an average cost of $0.30 per linear foot requiring baseboard.

To find out how much it will cost Miller to purchase baseboard for her room, we can use the CER (Conversion, Equation, and Re-substitution) strategy.

Conversion:

We can calculate the perimeter of the room by adding the lengths of all four sides:

Perimeter = 2(Length + Width) - 2(Doorway Width)

Perimeter = 2(15 + 20) - 2(3)

Perimeter = 64 feet

So, Miller will need 64 feet of baseboard.

Equation:

To calculate the cost of the baseboard, we can use the formula:

Cost = Length * Cost per linear foot

In this case, the length is 64 feet and the cost per linear foot is $0.30.

Cost = 64 * 0.30

Cost = $19.20

Therefore the final answer is that it will cost Miller $19.20 to purchase baseboard for her room, assuming an average cost of $0.30 per linear foot requiring baseboard.

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Here, a is called the numerator and b is called the denominator.

Total weight of the bag of pretzels = 34 ounce

Elisa shares this among her two sisters equally.

Share of pretzels each sister gets = 34 / 2 = 17 ounces

We need this amount in pounds.

To show that w is in the subspace of R4 spanned by V1, V2, and V3, we need to find constants c1, c2, and c3 such that:

w = c1V1 + c2V2 + c3V3

We can write this as a matrix equation:

| 1 -4 -9 -4 | | c1 | | -2 |

| 6 3 5 1 | x | c2 | = | -1 |

| 2 4 11 -8 | | c3 | | -1 |

We can solve this system of equations using row reduction:

| 1 -4 -9 -4 | | c1 | | -2 |

| 6 3 5 1 | x | c2 | = | -1 |

| 2 4 11 -8 | | c3 | | -1 |

R2 = R2 - 6R1

R3 = R3 - 2R1

My balance grows faster than my friends balance.

Step-by-step explanation:

where

t = Time

Average rate from t=2 to t=6 is given by

\(\dfrac{t(6)-t(2)}{6-2}\\ =\dfrac{300(1.05)^6-300(1.05)^2}{4}\\ =\mathbf{17.82}\)

My friend's balance is given by

\(y=340+10t\)

Average rate is given by

\(\dfrac{t(6)-t(2)}{6-2}\\ =\dfrac{(340+10\times 6)-(340+10\times 2)}{4}\\ =\mathbf{10}\)

My balance grows faster than my friends balance.
