PLease answer as soon as possible
yulyashka [42]

Answer:

No

Step-by-step explanation:

Every x value in the domain should only have 1 y value. In the graph, for x=5 (the input) there are 2 y values (6 and -6) so this is not a function.

Vector u has initial points at (21,12) and it’s terminal point at (19,-8). Vector v has a direction opposite that of u. Who’s ma
8_murik_8 [283]

The correct form of vector v expressed as a <em>linear</em> combination of the <em>unit</em> vectors i and j is \vec v = 10\,\hat{i} + 100\,\hat{j}.

<h3>What is the value of a vector with respect to another vector?</h3>

First, we need to determine the value of the vector u by subtracting two vectors whose <em>initial</em> points are at the origin:

\vec u = (19\,\hat{i} - 8\,\hat{j}) - (21\,\hat{i} + 12\,\hat{j})

\vec u = - 2\,\hat{i} - 20\,\hat{j}     (1)

According to the statement, vector v is antiparallel to vector u and its magnitude is five times as the magnitude of vector v, which means that (1) must be multiplied by two scalars:

\vec v = - 1 \,\cdot \, 5\cdot \vec u      (2)

Please notice that antiparallelism is represented by the scalar - 1, whereas the dilation is represented by the scalar 5.

\vec v = 10\,\hat{i} + 100\,\hat{j}

The correct form of vector v expressed as a <em>linear</em> combination of the <em>unit</em> vectors i and j is \vec v = 10\,\hat{i} + 100\,\hat{j}.

<h3>Remark</h3>

The statement presents typing mistakes, correct form is shown below:

<em>Vector u has initial points at (21, 12) and its terminal point at (19, - 8). Vector v has a direction opposite that of u, whose magnitud is five times the magnitud of v. Which is the correct form of vector v expressed as a linear combination of the unit vectors i and j?</em>

Relationship B has a lesser rate than Relationship A. The graph represents Relationship A.
choli [55]

we have that

1) Relationship B has a lesser rate than Relationship A

2) The graph represents Relationship A

we know that

The rate is equal to the slope of the linear equation in the graph

Step 1

<u>Find the slope of the Relationship A</u>

we have

A(1,3)\\B(2,6)

we know that

The formula to find the slope m between two points is equal to

m=\frac{(y2-y1)}{(x2-x1)}

substitute the values

m=\frac{(6-3)}{(2-1)}

m=\frac{(3)}{(1)}

mA=3

Step 2

<u>Find the equation that could represent Relationship B</u>

we know that

Relationship B has a lesser rate than Relationship A

so

the slope of the Relationship B is less to the slope of the Relationship A

mB < 3

therefore

<u>the answer is</u>

y=x ------> because the slope is 1

y=(3/2)x ------> because the slope is 1.5

A recent poll asked people whether they supported passing a constitutional amendment to ban burning of the national flag using a
Natalka [10]

Answer:

Step-by-step explanation:

Hello!

You are asked to test the difference of the population means of the opinion of  men and women over a constitutional amendment to ban burning the national flag.

Population 1 (women)

Sample n₁= 400

X[bar]₁= 80.6

Population 2 (men)

n₂= 586

X[bar]₂= 77.6

σ₁= σ₂ = σ =3.5

To test whether there is a difference between the opinion of people about the amendment regarding their gender the hypothesis is:

H₀: μ₁ - μ₂ = 0

H₁: μ₁ - μ₂ ≠ 0

α: 0.05

The statistic to use is a pooled Z:

Z=<u> (X[bar]₁ - X[bar]₂) - (μ₁ - μ₂)  </u> ~N (0;1)

                σ*√(1/n₁ + 1/n₂)

The critical region for this hypothesis is two tailed:

Z_{\alpha /2} = Z_{0.025} = -1.96

Z_{1-\alpha /2} = Z_{0.975} = 1.96

Z=<u> (X[bar]₁ - X[bar]₂) - (μ₁ - μ₂)  </u> = <u>        (80.6-77.6) - 0       </u> = 13.215

                σ*√(1/n₁ + 1/n₂)                 3.5√(1/400 + 1/586)

Since the calculated Z-value is greater than the right critical value -81.96) the decision is to reject the null hypothesis. There is significant evidence to conclude that there is no difference between the population means of the opinion about the constitutional amendment to ban the burning of the national flag of women and men.

I hope it helps!
