What is the value of y in the equation 5x + 2y = 20, when x = 0.3?

2 answers:

7 0

First substitute x for 0.3 and multiply by 5, and you get 1.5 Now we want to isolate the 2y so we subtract 1.5 on both sides. So we have a new equation of 2y=18.5 Now to isolate the y we divide 2 by both sides and you get y=9.25

Answer:

y=9.25

Step-by-step explanation:

5x+2y=20

5(.3)+2y=20

1.5+2y=20

2y=20-1.5

2y=18.5

y=18.5/2

y=9.25

QUESTION 29 Write the equation of the function.

sweet [91]

Answer:

y = 2 -√(x+1)

Step-by-step explanation:

The square root function is reflected across the x-axis and shifted 1 unit to the left and 2 units up.

y = -√x . . . . . reflects the function across the x-axis

y = -√(x+1) . . . shifts the reflected function 1 unit to the left

y = 2 -√(x +1) . . . shifts the above function 2 units up

The graph is of the equation y = 2 -√(x+1).

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.
