Answer:

-14 is the correct answer

Answer: C, D, E

Step-by-step explanation:

A negative multiplied by a negative is a positive. In option A, for example, a one is implied in front of the first negative sign, thus: -1 * (-1/2) = 1/2. The same goes for option B, leaving C, D, and E as the only negative values.

y = -x equation does not represent a direct variation.

y = 3x + 2

y=-3x

y = 0.5x

equations are represent a direct variation

How can you tell if there is a direct variation?

Simply build ratios from a table of values if you have one and wish to determine whether the data indicate a direct variation. You have a straight variation if all the ratios are the same.

The constant of variation is k = = 3, for instance, if y varies straight as x and y = 6 when x = 2. So, y = 3x serves as the equation to describe this direct variation.

If you have 15 quarters, 10 dimes, 10 nickels and 10 pennies, then the probabilities of getting quarter, dimes, nickels and pennies are 0.33, 0.22, 0.22 and 0.22 respectively.

Total number of quarters = 15 quarters

Total number of dimes = 10 dimes

Total number of nickels = 10 nickels

Total number of pennies = 10 pennies

Total number of coins = 15+10+10+10 = 45

The probability of getting a quarters = 15/45

= 0.33

The probability of getting a dimes = 10/45

= 0.22

The probability of getting a nickel = 10/45

= 0.22

The probability of getting penny = 10/45

= 0.22

Hence, if you have 15 quarters, 10 dimes, 10 nickels and 10 pennies, then the probabilities of getting quarter, dimes, nickels and pennies are 0.33, 0.22, 0.22 and 0.22 respectively.

The diagonal of the rectangular solid that has l = 8, w = 4, h = 2, is calculated as: d = 2√21 units.

A rectangular solid has a length (l), height (h), and width (w). The diagonal of the rectangular solid, d, can be calculated using the given formula below:

Diagonal of rectangular solid (d) = √(l² + w² + h²).

Given the following dimensions of the rectangular box:

Substitute l = 8, w = 4,a nd h = 2 into the equation d = √(l² + w² + h²):

Diagonal of rectangular solid (d) = √(8² + 4² + 2²)

Diagonal of rectangular solid (d) = √(64 + 16 + 4)

Diagonal of rectangular solid (d) = √84

Simplify √84 further

Diagonal of rectangular solid (d) = √(4 × 21)

Diagonal of rectangular solid (d) = 2√21 units

Therefore, the rectangular solid has a diagonal that is: 2√21

The spread and consistency of data.

Y is 2.25 when x is 9.

The relationship between two values where their ratio equals a constant number is known as a direct proportion or direct variation. It is symbolized by the proportional sign (). According to the direct proportion formula, if y is directly proportional to x, we can state that y = kx, where k is a constant. The generic form of the direct proportion equation is also y = kx. where k is the proportionality constant.

Given Data

If x and y vary directly and y is 24 when x is 6, find y when x is 9.​

It is direct proportional

So,

y = kx

To find constant,

k = [tex]\frac{y}{x}[/tex]

x = 6 and y = 24

k = [tex]\frac{6}{24}[/tex]

k = [tex]\frac{1}{4}[/tex]

When x = 9,

k = [tex]\frac{1}{4}[/tex]

y = kx

y = [tex]\frac{1}{4}[/tex](9)

y = [tex]\frac{9}{4}[/tex]

y = 2.25

Y is 2.25 when x is 9.

Answer:



m < 1 = 146

m < 3 = 146

m < 4 = 34

Step-by-step explanation:

Angles 2 and 3 are suplementary angles that equal 180

angle 2 + angle 3 = 180

34 + angle 3 = 180

angle 3 = 180 - 34

angle 3 = 146

angles 2 (34 degrees) and 4 and angles 1 (146 degrees) and 3 are congruent so...

m < 1 = 146

m < 2 = 34

m < 3 = 146

m < 4 = 34

Hope this helps! :)

Answer:

[tex]m \angle 1= \boxed{146}\;^{\circ}\\\\m \angle 3= \boxed{146}\;^{\circ}\\\\m \angle 4= \boxed{34}\;^{\circ}[/tex]

Step-by-step explanation:

Angles on a straight line sum to 180°.

⇒ m∠1 + m∠2 = 180°

⇒ m∠1 + 34° = 180°

⇒ m∠1 = 146°

Vertical Angle Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Applying the Vertical Angle Theorem:

The operation of Subtraction can be used to result in the smallest co-efficient term on the x term.

In the given question, Two functions are given f(x) = 3x - 1, and g(x) = 3x + 4. Now we have to find out which mathematical operation results in the smallest co-efficient term on x. We know that the basic Operations are:    

=> Now, we use the operation of Subtraction for the two functions. Which can be calculated by: f(x) - g(x), Calculating we get:

=> (3x - 1) - (3x - 4)

=> 3x -1 -3x + 4

The percent of Thompson's Scores that are between 64.2 and 67.4 is 69% to 94%

given data

a mean of about 70.6 strokes

a standard deviation of about 3.2 strokes

Applying the 68%, 95%, and 99.7% Rule. This rule says that standard deviations is changed to percentages when:

Hence we calculate how many standard Deviations that gives 73.8 as follows

since the73.8 is greater than the mean we add the SD to the mean

70.6 + 3.2 = 73.8

73.8 is 1 SD but we are looking for value greater than 73.8. This should be just above 73.8, hence from 2 SD which is 95%

What percent of Thompson's scores are between 64.2 and 67.4

Applying the 68%, 95%, and 99.7% Rule

The numbers asked is less than the mean hence we subtract

70.6 - 3.2 = 67.4    ( 1 SD = 68% )

70.6 - 3.2 - 3.2 = 64.2    ( 2 SD = 95% )

The unknown measures of the right angle triangle are m∠V = 69° , RV = 12.85 and m∠R = 21°

A right triangle is a triangle that has one of its angles as 90 degrees.

Therefore, the side and angles of a right triangle can be found using trigonometric ratios.

Hence,

tan v = opposite / adjacent

opposite side = 12

adjacent side = 4.6

Therefore,

tan V = 12 / 4.6

v = tan⁻¹ 2.60869565217

v = 69.0265065627

m∠V = 69°

Let's find  m∠R

m∠R = 180 - 69 - 90

m∠R = 21°

Let's find RV

sin 69° = opposite / hypotenuse

sin 69 = 12 / h

cross multiply

h = 12 / sin 69

h = 12 / 0.93358042649

h = 12.8537402885

RV = 12.85 units
