The equation that represents the data in the table is y = 4x – 2.

Solution:

Take any two point from the table.

Let the points taken are (0, –2) and (3, 10).

x_1=0, y_1=-2, x_2=3, y_2=10

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{10-(-2)}{3-0}

$m=\frac{12}{3}

m = 4

Using point-slope formula,

y-y_1=m(x-x_1)

y-(-2)=4(x-0)

y+2=4x

Subtract 2 from both sides, we get

y = 4x – 2

The equation that represents the data in the table is y = 4x – 2.

zlopas [31]

Answer:

H0: mu = 8.9 fl oz.\\\\

Ha: mu ≠8.9 fluid oz

Step-by-step explanation:

Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz

For testing this claim, in Statistics we perform a certain measures called hypothesis testing.

For this first step is to create null and alternate hypothesis.

Normally null hypothesis would have some statistic = something

Here we want to test the mean weight of perfume

Hence null hypothesis would be

H0: mu = 8.9 fl oz.

Alternate hypothesis would be opposite of this claim

i.e.

Ha: mu ≠8.9 fluid oz

Hence answer is

H0: mu = 8.9 fl oz.\\\\

Ha: mu ≠8.9 fluid oz

AveGali [126]

complete question:

Find the volume of the cylinder.

Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.

Radius = 4 and height = 8.

Answer:

volume of a cylinder ≈ 402.30  unit cube

Step-by-step explanation:

The question you to find the volume of a cylinder with a height of 8 and radius of 4. The volume of a cylinder can be represented below

volume of a cylinder =  πr²h

where

h = height

r = radius

h = 8

r = 4

volume of a cylinder =  πr²h

volume of a cylinder =  π × 4² × 8

volume of a cylinder =  π × 16 × 8

volume of a cylinder = 128  π

volume of a cylinder =  128 × 3.143

volume of a cylinder = 402.304

volume of a cylinder ≈ 402.30  unit cube
