Answer is A

- The domain is what x values can exist on a curve, or graph; the y for range. In this case, the domain is restricted, given another condition, to essentially a list of x-values, namely -5, 0 and 1. Note that on the function you have mentioned can exist anywhere in x normally, and hence anywhere in y such that the relationship between the two holds, as it is one-to-one and has no discontinuities and asymptotes; basically anywhere x or y cannot exist, but is restricted as an extra condition. Going back to the one-to-one point; this means one x-value to one y-value, or every x has a unique y. So in this case, all we have to do is plug in the x-value into the function to find it’s unique y-value. That being 2, -2 and -2 and 4/5 going from left to right.

Simplify: |3 – 8| - (12 divided by 3 + 1) to the power of 2

Harlamova29_29 [7]

Answer:

-4

Step-by-step explanation:

Assuming that the following equation is correct, begin by solving the operations within parentheses and absolute value expressions.

|3 - 8| - $(\frac{12}{3+1} )^2$

|-5| - $(\frac{12}{4} )^2$

The absolute value of -5 is 5; -5 is five units away from 0. 12/4 is equal to 3.

5 - $3^2$

5 - 9 = -4

The simplified expression is equal to -4.

You measure 25 turtles' weights, and find they have a mean weight of 31 ounces. Assume the population standard deviation is 12.8

Firlakuza [10]

Answer:

Margin of error = 4.21 ounces

Step-by-step explanation:

According to the Question,

Given That, You measure 25 turtles' weights, and find they have a mean weight of 31 ounces. Assume the population standard deviation is 12.8 ounces

Therefore, Sample mean = 31 ounces , Sample size(n) = 25 , Alpha(α) = 0.10 & Population standard deviation(σ) = 12.8 ounces

Thus, Margin of error = $Z_{critical}$ × σ / √n ( $Z_{critical}$ at α=.010 is 1.645)

Putting The Values, We get

1.645 × (12.8 / √25 ) ⇒ 4.2112 ≈ 4.21

Thus, the maximum margin of error associated with a 90% confidence interval for the true population mean turtle weight is 4.21 ounces

2x+3y=9xy is this a linear or non-linear function pls give steps if posible

liq [111]

Answer:

Step-by-step explanation:

To Differentiate A linear Function from a non-linear one we have Several rules.

1: check the Variables exponent degree of the function if the exponent is zero or 1 of the function that's the function is linear.

2: if it's not 0 or 1 and Greater than 1 than it's non linear function also if the exponent is of any negative value like -1 or -2 than it's also a non linear function. The Given function is a non linear function because the 9xy value has two variables multiplied if we add the exponent values together which are 1+1 = 2 hence proved it's a non linear function. One More Thing a graph of non linear function will be always other than that of a straight line.

I recommend that you download photomath, it is an app that takes a photo of the equation and answers it most of the time.
