Which equation does not represent a linear function of x?

Mathematics
1 answer:
Natasha_Volkova [10]3 years ago

The answer is D) y = 3x^2 - 2, because the x is squared, making the function a quadratic function. Quadratic functions will be in the shape of a parabola (a u or upside down u). 

Meanwhile any function whose degree (highest exponent of x) is one is a linear function. It will have be a straight line.

What is the inverse function of d(x) = 2x - 4?
Naddik [55]
Let d(x) = 2x - 4

Or

y = 2x - 4

We have replace x = y

x = 2y - 4

Now Isolate "y"

x + 4 = 2y

Pass "2" dividing

(x + 4) / 2 = y

y = x/2 + 2

Or

d(x)^-1 = x/2 + 2

Assume that for a particular tire brand, the probability of wearing out before 30,000 miles is 0.25. For someone who buys a set
Hatshy [7]

Answer:

The probability that all will last at least 30,000 miles is 0.3164.

Step-by-step explanation:

Consider the provided information.

For a particular tire brand, the probability of wearing out before 30,000 miles is 0.25. Someone who buys a set of four of these tires,

That means the probability of not wearing out is 1-0.25 = 0.75

Now use the binomial distribution formula.

^nC_r (p^{n-r})(q^r)

Substitute p = 0.25, q=0.75, r=4 and n=4

^4C_4 (0.25)^{4-4}(0.75)^4

1 \times 0.75^4

0.3164

The probability that all will last at least 30,000 miles is 0.3164.
