Answer:

No (1,8) is not a solution to 19x+3y=2.

However, (1,8) is a solution to 3x+y=11.

Step-by-step explanation:

(1,8)

The one represents the x shown in each equation, the eight represents the y.

Substitute the one in for the x and the eight in for the y.

19x+3y=2

19(1)+3(8)

3x+y=11

3(1)+(8)

Next, solve the equation.

19(1)+3(8) = 43

3(1)+(8) = 11

As you can see, 43 does not equal 2.

But, 11 does equal 11.

Find the domain and range from the function listed below.
Phantasy [73]

Answer:

Domain; [-1, 3)

Range; (-5, 4]

Step-by-step explanation:

The domain of a function is defined as the set of x-values for which the given function is real and defined. In order to find the domain of the graphed function, we have to determine the lowest and the highest x-values for which the function is defined. From the graph, the least value of x is -1 while the greatest x value is 3 but the function is not defined at this point. Therefore the domain of the function is;

[-1, 3)

On the other hand, the range refers to the set of y-values for which the function is real and defined. The least y-value from the given graph is -5 while the greatest y -value is 4. Therefore, the range of the graphed function is;

(-5, 4]

Vedmedyk [2.9K]

Answer:

a) 151lb.

b) 6.25 lb

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}.

In this problem, we have that:

\mu = 151, \sigma = 25, n = 16

So

a) The expected value of the sample mean of the weights is 151 lb.

(b) What is the standard deviation of the sampling distribution of the sample mean weight?

This is s = \frac{\sigma}{\sqrt{n}} = \frac{25}{\sqrt{16}} = 6.25
