I need help on this question

Answer:

B

Step-by-step explanation:

Had it on Khan Academy.

True statement for the given graph is the point [tex](3,9)[/tex] shows that [tex]9[/tex] liters of red paint are needed for every [tex]3[/tex] liters of blue paint.

" Graph is defined as diametrical representation of the relation between the variables on the coordinate plane along x-axis and y -axis."

According to the question,

As given in the graph,

Graph represents the linear relation between red paint and blue paint.

'x -axis' on the graph represents the blue paint

'y- axis' on the graph represents red paint

A. The point [tex](0,0)[/tex] shows that any amount of red and the blue paint will make same shade of purple.

From the graph coordinates [tex](1,3)[/tex] and [tex](2, 6)[/tex]represents that proportion of blue : red to make required purple shade is [tex]1: 3[/tex].

Hence, Option A is not a correct answer.

B.  The point [tex](3,9)[/tex] shows that [tex]9[/tex] liters of red paint are needed for every [tex]3[/tex] liters of blue paint.

Coordinate [tex]( 3,9)[/tex] on the graph represents the ratio of blue : red [tex]= 3 : 9[/tex] which is equals to [tex]1:3[/tex] .

Hence, Option(B) is the correct answer.

Answer:

[tex]CI =0.894%[/tex]

Step-by-step explanation:

From the question we are told that:

Sample size [tex]n=4[/tex]

Standard deviation [tex]\sigma=0.76\% of \=x[/tex]

Confidence level [tex]\mu =90\%=0.90[/tex]

Degree of Freedom [tex]Df=n-1=3[/tex]

Therefore

Test T from table is given

 [tex]t=2.353[/tex]

Generally the equation for Confidence interval CI is mathematically given by

 [tex]CI =t*\frac{\sigma}{\sqrt{n}}[/tex]

 [tex]CI =2.353*\frac{0.76}{\sqrt{4}}[/tex]

 [tex]CI =0.894%[/tex]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Sample size, n = 39

Correlation Coefficient, r = 0.273

The hypothesis test to examine if there is a positive correlation :

H0 : ρ = 0

If there is a positive correlation, then ρ greater than 1

H0 : ρ > 1

The test statistic :

T = r / √(1 - r²)/(n - 2)

T = 0.273 / √(1 - 0.273²)/(39 - 2)

T = 0.273 / 0.1581541

T = 1.726

The Pvalue using a Pvalue calculator can be be obtained using df = n - 2, df = 39 - 2 = 37

The Pvalue = 0.0463

α= .10 and α= .05

At α= .10

Pvalue < α ; Hence, we reject H0 and conclude that a positive correlation exists

At α= 0.05 ;

Pvalue < α ; Hence, we reject H0 and conclude that a positive correlation exists

Option B is correct, the value of tan 74° is 24/7

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We have to find the value of tan74°

The tan function is ratio of opposite side and adjacent side.

We have to find the opposite side of angle 74°,

The opposite side has length 24

Now let us find the adjacent side of angle 74 which is 7

tan 74° = 24/7

Hence, option B is correct, the value of tan 74° is 24/7.

Step-by-step explanation:

Answer:

The interquartile range (IQR) for town A, 15° is less than the IQR for town B, 20°.

Step-by-step explanation:

From the boxplot Given ;

Town A :

The first quartile, Q1 = 15

Third quartile, Q3 = 30

The interquartile range, IQR = Q3 - Q1 = 30 - 15 = 15°

TOWN B :

The first quartile, Q1 = 20

Third quartile, Q3 = 40

The interquartile range, IQR = Q3 - Q1 = 40 - 20 = 20°

The interquartile range (IQR) for town A, 15° is less than the IQR for town B, 20°.

When using an equation editor to create your answers, you need to be careful to make the distinction between the multiplication symbol × and the variable x. Note, too, that exponents generally must be written using the superscript form. x10 and x¹⁰ are not the same thing.

Answer:

[tex]x \ge 1[/tex]

Step-by-step explanation:

Given

[tex]\sqrt{6(x - 1)} \div \sqrt{3x^2[/tex]

Required

x for [tex]which[/tex] the function is [tex]de fi ned[/tex]

To do this, we set the numerator root [tex]\ge 0[/tex]

So, we have:

[tex]6(x - 1) \ge 0[/tex]

Divide by 6

[tex](x - 1) \ge 0[/tex]

Solve for x

[tex]x \ge 1[/tex]

Also, we set the denominator greater than 0:

[tex]3x^2 > 0[/tex]

Divide by 3

[tex]x^2 > 0[/tex]

Take square roots

[tex]x > 0[/tex]

So, we have:

[tex]x > 0[/tex] and [tex]x \ge 1[/tex]

Combine both to give:

[tex]x \ge 1[/tex]

Answer:

Step-by-step explanation:

First differences are ...

  x -4, 8 -x, y -8, 20 -y

Then second differences are ...

  (8 -x) -(x -4)

  (y -8) -(8 -x)

  (20 -y) -(y -8)

Each of these is said to be 2, so we have ...

  12 -2x = 2   ⇒   x = 5

  28 -2y = 2   ⇒   y = 13

And an equation we can use to check:

  x +y -16 = 2   ⇒   5 +13 -16 = 2 . . . . true

Answer:

16a^12 b^16

Step-by-step explanation:

that's the answer. just multiply out the powers

Answer:

16*(a^12)*(b^16)

Step-by-step explanation:

In order to solve this problem, we can split these term into three separate terms.

[tex]{(2 {a}^{3} {b}^{4})}^{4} = {2}^{4} \times {( {a}^{3}) }^{4} \times {( {b}^{4} )}^{4} [/tex]

2 to the power of 4 is 16.

[tex] {2}^{4} = 16[/tex]

As for the terms a and b, the two exponents can multiply with each other.

[tex] {( {a}^{3} )}^{4} = {a}^{(3 \times 4)} = {a}^{12} [/tex]

[tex] {( {b}^{4} )}^{4} = {b}^{(4 \times 4)} = {b}^{16} [/tex]

Now, we can directly multiply the values together by combining into one term.

Hence, the final answer is

[tex]16 {a}^{12} {b}^{16} [/tex]

Step-by-step explanation:

oprion C is the answer. The two line are congruent
