Solution

             To    find   Which two numbers on the number line has  an

             absolute value of  3  

            Absolute   value   means    " how  far   a  number    is   from  

           zero "  .

           "3"    is    3    away   from   zero  .

           and    " -3 "   is  also   3    away   from  zero  .

           i.e

                    |  0  - 3  |   =   3

                    |  3 - 0 |  =  3

                    So ,  the  absolute   value  of   "3 "    is    3

                   similarly  , absolute  value  of  "3 "   is   3  .

                  Hence  , the  two  numbers   are   -3    and   3

xeze [42]
You can write an equivalent expression with this knowledge by taking a two numbers, and multiplying both of them by a number. You can extract the number by taking the gcf of both of them, and dividing them both by it and putting the numbers in a parenthesis and multiplying the numbers by the gcf.<span />

Consider the following hypothesis test: H 0: 20 H a: &lt; 20 A sample of 60 provided a sample mean of 19.5. The population stand
viva [34]

Answer:

We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.          

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 60

Sample mean, \bar{x} = 19.5

Sample size, n = 60

Alpha, α = 0.05

Population standard deviation, σ = 1.8

First, we design the null and the alternate hypothesis

H_{0}: \mu = 20\\H_A: \mu < 20

We use One-tailed z test to perform this hypothesis.

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{19.5 - 20}{\frac{1.8}{\sqrt{60}} } = -2.151

Now, z_{critical} \text{ at 0.05 level of significance } = -1.64

Since,  

z_{stat} < z_{critical}

We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.

Musya8 [376]

Answer:

see below

Step-by-step explanation:

The equation of a circle can be written as

( x-h) ^2 + (y-k) ^2 = r^2

( x-3)^2 + (y+4) ^2 = 36

Rewriting this equation

( x - 3)^2 + ( y - -4)^2 = 6^2

The center is at (3,-4) and the radius is at 6

Susan did not use the formula correctly.

It is x-h and y-k so she needed to rewrite to get the equation in the proper form

Also the radius is r^2 not r/2
