Answer:

y = -4
y = -8

Step-by-step explanation:

For the first possible answer (y = -4):

Simplify: 6 + y = 2
Subtract 6 from each side, so it now looks like this: y = -4

I don't know how to explain the second one, I'm sorry!

Answer:

y = -8

y = -4

Step-by-step explanation:

The equation |6 + y| = 2 can only be true when 6 + y = -2 and 6 + y = 2. This is because:

|-2| = 2

and

|2| = 2

First, lets find for what y values the equation 6 + y = -2 is true. Solve for y:

6 + y = -2

Subtract 6 from both sides.

y = -8

So now we have one of the values of y.

To find the second value of y, we must solve for y in the equation 6 + y = 2:

6 + y = 2

Subtract 6 from both sides.

y = -4

So the two values of y are -8 and -4.

I hope you find my answer and explanation to be helpful. Happy studying.

The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards (according to GolfWeek). Assume th

Usimov [2.4K]

Answer:

a) $f(x) = \frac{1}{25.9}$

b) 0.2046 = 20.46% probability the driving distance for one of these golfers is less than 290 yards

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

The probability density function of the uniform distribution is:

$f(x) = \frac{1}{b-a}$

The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards.

This means that $a = 284.7, b = 310.6$ .

a. Give a mathematical expression for the probability density function of driving distance.

$f(x) = \frac{1}{b-a} = \frac{1}{310.6-284.7} = \frac{1}{25.9}$

b. What is the probability the driving distance for one of these golfers is less than 290 yards?

$P(X < 290) = \frac{290 - 284.7}{310.6-284.7} = 0.2046$

0.2046 = 20.46% probability the driving distance for one of these golfers is less than 290 yards

P(x) is a polynomial with integer coefficients and p(-3) = 0.

natka813 [3]

Answer:

x + 3 is a factor of the polynomial.

Step-by-step explanation:

We have been given that p(x) is a polynomial with integer coefficient.

Also p(-3)=0

Since, p(-3) =0, hence, we can say that -3 is a zero of the polynomial.

Now, we apply factor theorem.

Factor Theorem: If 'a' is a zero of a function f(x) then (x-a) must be a factor of the function f(x).

Applying this theorem, we can say that (x+3) must be a factor of the polynomial.

Hence, first statement must be true.

Answer:

i am going to help you to understand this problem. if it is written with 10 0s it will be the billion place. because of the ten ones it will be 0,000,010, and because of the ten two's, which is 20, it will be 0,000,030. and when i searched up on google, and watched an episode of number blocks, no, 30 is not a square number OR a cube number.
