Solve for x.
x = [?]
4x - 2/3x 14

Solve For X.x = [?]4x - 2/3x 14

Answers

Answer 1

Answer:

x = 24°

Step-by-step explanation:

Here's your solution

=> (4x - 2) + (3x + 14) = 180°

=> 7x + 12 = 180°

=> 7x = 180° - 12°

=> 7x = 168°

=> x = 168°/7

=> x = 24°

Use the value of the linear correlation coefficient r to find the percentage of the total variation that can be explained by the linear relationship between the two variables. r = 0.234 (Your answer should be a percent rounded to two decimal places as needed.)

Answers

Answer:

5.47% of the total variation between the two variables can be explained by the regression line.

Step-by-step explanation:

Given :

R value = 0.234

The R value is the correlation Coefficient ; which gives the type and level of correlation between two variables.

However, to Obtian the percentage variation which can be explained by by the regression line, we have to obtain the Coefficient of determination, R².

R² value is Obtained by taking the squared of the correlation Coefficient

Hence,

R² = 0.234² = 0.054756

R² = 0.05476 * 100% = 5.4756%

Hence, R² = 5.48%

This is interpreted as ; 5.47% of the total variation between the two variables can be explained by the regression line.

Example 5:
Mrs. Williams writes the following number on the board.
276,954
She instructs her students to write a number where the value of the 6 in their number is 10
times greater than the value of the 6 in the number on the board. Duwan writes the number
286,123. Is his answer correct? Explain how you know.

Answers

Answer:

No Duwan is in incorrect.

Step-by-step explanation:

When it asks for a number to be 10x greater, the answer would be in a digit that is 1 greater. For example 10x greater than 10 would be 100. You move the digit up once. An answer that Duwan could have used is: 260,000.

What is the approximate length of the missing side of a
right triangle with hypotenuse of 16 cm and other side of
15 cm?

Answers

Answer:

The approximate length of the missing side is of 5.57 cm.

Step-by-step explanation:

Pythagorean Theorem:

In a right triangle with sides a and b and hypotenuse c, the Pythagorean theorem states that:

[tex]a^2 + b^2 = c^2[/tex]

In this question:

[tex]a = 15, c = 16[/tex]

We want to find b. Then

[tex]a^2 + b^2 = c^2[/tex]

[tex]15^2 + b^2 = 16^2[/tex]

[tex]b^2 = 256 - 225[/tex]

[tex]b^2 = 31[/tex]

[tex]b = \sqrt{31}[/tex]

[tex]b = 5.57[/tex]

The approximate length of the missing side is of 5.57 cm.

Maria and her friends eat pizza for lunch.
There are 6 pizzas with 10 slices each. If
Maria and her 15 friends eat 3 slices each,
how many slices are left over?

Answers

Answer:

15 slices

Step-by-step explanation:

The total number of slices is equal to 60 (6x10=60) and if each friend eats 3 slices, they will all collectively eat 45 slices (15x3). If they eat 45 out 60 slices they will have 15 slices left over (60-45=15).

Point P lies on circle C, x^2+y^2=36. There are two unique tangents to circle D, x^2+y^2=18 that pass through point p. What is the measure of the angle between the two tangent lines?

Answers

Answer:

90°

Step-by-step explanation:

Refer to attached

Red circle is C with radius 6 and green circle is D with radius √18.

PM and PN are tangents to circle D.

M and N are right angles as tangents are perpendicular to radius.

We need to find the measure of ∠MPN.

We'll work out this angle using trigonometry:

OM / OP = sin (∠MPO) sin (∠MPO) = √18/6 = √2/2m∠MPO = arcsin ( √2/2) = 45°

∠NPO is same as ∠MPO, therefore:

m∠MPN = 45°*2 = 90°

Answer and Step-by-step explanation:

To get the x values, we can plug in the y values and solve for x.

1 = 0.5x + 2

Subtract 2 from both sides.

-1 = 0.5x

Divide both sides by 0.5.

-2 = x

2 = 0.5x + 2

Subtract 2 from both sides.

0 = 0.5x

Divide both sides by 0.5.

0 = x

3 = 0.5x + 2

Subtract 2 from both sides.

1 = 0.5x

Divide both sides by 0.5.

2 = x

to Valentina. To the nearest tenth of a meter, what is the distance that Chloe walked to
get back to Valentina?

Answers

Answer:

86 meters was back on valentina,

The distance is 126.67 meters that Chloe walked to get back to Valentina.

What is a right angle triangle?

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.

Given that,

Valentina and Chloe are standing next to each other.

The distance travelled by Chloe in south direction = 86 meters.

And distance covered in west direction = 93 meters

Since, Valentina does not move from its place.

To find the nearest distance that Chloe come back to Valentina,

Use Pythagoreans theorem,

(Hypotenuse)² = (Base)² +  (Perpendicular)²

Let the required distance is x meters

(x)² = (86)² + (93)²

x² = 7396 + 8649

x² = 16045

x = 126.67

The required distance IS 126.67 meters.

For example, “How old am I?" is not a statistical question, but “How old are the students in my school?” is a statistical question.  Therefore, when we look at the options, the second option is the best.

Explanation 2:  To find the mode we have to find which number is most frequent through out the set.  When we look at the numbers, there are 3 numbers that have 56.  Therefore, 56 is the mode.

There are five blue jelly beans, two red jellybeans, one orange jellybean and 2 pink jellybeans in a bag. Once a Jellybean is drawn, it’s not replaced. Find the probability of selecting a blue jellybean and then a pink jellybean.


A) 1/10

B) 1/9

C) 1/100

D) 1/125

Thank you! Have a great day! :D

Answers

Answer:

1/9

Step-by-step explanation:

Probability = Expected outcome/Total outcome

Since we have five blue jelly beans, two red jellybeans, one orange jellybean and 2 pink jellybeans in a bag

Total outcome = 5 + 2 + 1 + 2

Total outcome = 10

Probability of selecting a blue = 5/10 = 1/2

Since it is not replaced, the total ball remaining will be 9

If pink jellybean is picked after, the probability of picking a pink will be 2/9

Hence probability of selecting a blue jellybean and then a pink jellybean = 1/2 * 2/9 = 1/9
