Explain how you calculate the constant of variation.

Answers

Answer 1

Answer:Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.

Step-by-step explanation:The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.

Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize. Suppose that Isaac is going to buy 6 boxes of this cereal, and let X represent the number of prizes he wins in these boxes. Assume that these boxes represent a random sample, and assume that prizes are independent between boxes. What is the probability that he wins exactly 2 prizes in the 6 boxes?

Answers

Answer: 0.3 on khan academy

Step-by-step explanation: ‍♂️

The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.

Calculation of the probability:

Since Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize this mean

So,

P(box containing prize) = 1/4 = p  =0.25

So,

q=1 - p

= 0.75

And total box (n)=6

Let us assume x be number of prize win.

So,

Probability that he will win exactly two prize is

P(X=2)=  [tex]\binom {6}{2}(0.25)^2(0.75)^4[/tex]

= 0.2966

=0.30(approx)

hence, The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.

Parallel lines a and b

Transversal c

Angle = 150°

y=6

Step-by-step explanation:

[tex]75 - 3.5y - 4y = 4y + 6[/tex]

Collect like terms and simplify

[tex] - 3.5y + 4y - 4y = 6 - 75 \\ - 11.5y = - 69[/tex]

Divide both sides of the equation by-3.5

[tex] \frac{ - 11.5y}{ -11.5} = \frac{ - 69}{ - 11.5} [/tex]

Simplify

[tex]y = 6[/tex]

The value of the y in the given equation is 6.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation.

Given that, an equation, 75 - 3.5y - 4y = 4y + 6, we need to find the value of y,

75 - 3.5y - 4y = 4y + 6

Combining the like terms,

75 - 6 = 4y + 4y + 3.5y

69 = 11.5y

y = 6

Hence, the value of the y in the given equation is 6.

Answers

Answer:

2

Step-by-step explanation:

you can make it like this

(1/4)^ x=1/16

so x=2

x = 2
This is because when you have a negative exponent like -x to rearrange it to a fraction and change the negative to a positive.
So 4^x would be the denominator and 1 would be the numerator.
So 1 / 4^x = 1 / 16
To achieve 16 from 4 you square it, therefore x = 2

Answer:

the quotient of Three-fourths and StartFraction 5 Over 6 EndFract is [tex]\frac{9}{10}[/tex]

Hence Option B is correct.

Step-by-step explanation:

We need to find quotient of Three-fourths and StartFraction 5 Over 6 EndFract

Writing in mathematical form: [tex]\frac{3}{4} \div \frac{5}{6}[/tex]

Solving, we get

(Converting division sign into multiplication the term is reciprocated so, 5/6 will become 6/5 )

[tex]\frac{3}{4} \div \frac{5}{6}\\=\frac{3}{4} \times \frac{6}{5}\\=\frac{3}{2} \times \frac{3}{5}\\=\frac{9}{10}[/tex]

So, the quotient of Three-fourths and StartFraction 5 Over 6 EndFract is [tex]\frac{9}{10}[/tex]

Hence Option B is correct.
