Answer:
• no
• yes
• yes
• no

Explanation:
To determine if each of the ordered pairs is a solution to y = 0, make sure the ordered pair has zero for the value of y.

• first ordered pair

(x, y)
(0, -2)

So, since this order pair has negative two for the value of y, it is not a solution.

• second pair

(x, y)
(-5, 0)

So, since this ordered pair has zero for the value of y, it is a solution.

• third ordered pair

(x, y)
(8, 0)

So, since this ordered pair has zero for the value of y, it is a solution.

• fourth solution

(x, y)
(-9, -6)

So, since this ordered pair has negative six for the value of y, it is not a solution.

Answer:

(0,-2) = No

(-5,0) = Yes

(8,0)  = Yes

(-9,-6) = No

Step-by-step explanation:

It says "solution to y = 0" so then look at the y-axis which is the second number in parenthesis.

Ex: (0, -2), y is -2 and x is 0.

Just make sure the second number is equal to 0, if not, then that is not the solution.

If f(x)=2x^2sqrt(x-2), complete the following statement f(6)
aliina [53]
F(6) means that for every value of x in the function, you plug in a 6. So, 
f(6) = 2(6)^2 + 5*sqrt((6) - 2)

This equals 82.

Answer:

y=5/17x+17 3/17

Step-by-step explanation:

put the points on slope to get 5/17. then use point slope form (y-y1)=m(x-x1) and plug in 41 for x1, 81 for y1, and 5/17x for m

A quality control engineer at a potato chip company tests the bag filling machine by weighing bags of potato chips. Not every ba
jekas [21]

Answer:

The test statistic is z = 1.865.

Step-by-step explanation:

The test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample.

H0: p = 0.11

This means that 0.11 is tested at the null hypothesis, and so:

\mu = 0.11

\sigma = \sqrt{0.11*0.89} = 0.3129

The engineer weighs 94 bags and finds that 16 of them are over-filled.

This means that:

n = 94, X = \frac{16}{94} = 0.1702

What is the test statistic?

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{0.1702 - 0.11}{\frac{0.3129}{\sqrt{94}}}

z = 1.865

The test statistic is z = 1.865.
