Square Root Functions <br> Help!
Montano1993 [528]

Answer:

f(x)=\sqrt{x-1}

Step-by-step explanation:

Hello there!

I take it you are asking for the expression of the function shown.

Since it is a normal square root function moved 1 unit to the right, you will subtract 1 from x.

Use this data in the problem below. Follow the steps carefully. Round to the nearest tenth. Lot 1: Week 1: 600 Week 2: 300 Week
Dafna11 [192]

Answer:

Step-by-step explanation:

The given data set is:

Week 1: 600

Week 2: 300

Week 3: 500

Week 4: 900

The following are the steps to find the standard deviation:

Step 1. Jim enters the data and calculates the average or mean.

Mean=\frac{600+300+500+900}{4}=\frac{2300}{4}=575

Step 2. Jim calculates the deviation from the mean by subtracting the mean from each value.

Data value (x)                                                             x-{\overline{x}}

600                                                                           25

300                                                                         -275

500                                                                         -75

900                                                                          325

Step 3. Jim squares each deviation to remove negative signs.

Data value (x)                                                           (x-{\overline{x}})^2

600                                                                       625

300                                                                    75625

500                                                                      5625

900                                                                   105625

Step 4. Jim sums the squares of each deviation and divides by the count for the variance.

Variance=\frac{625+75625+5625+105625}{4}=46875

Step 5.Jim takes the square root of the variance to find the standard deviation.

Standard deviation=\sqrt{46875}=216.50

Can some please help I’m stuck :(
Solnce55 [7]

Answer:

"I Only" is the correct answer

Step-by-step explanation:

Given inequality is:

-10>3x-6

In order to check which numbers are solution to the given inequality, we will put each number one by one in the inequality. If the inequality is true after putting the number, the number is the solution of the inequality.

So,

<u>I . -10</u>

Putting -10 in the inequality

-10>3x-6\\-10>3(-10)-6\\-10>-30-6\\-10> -36

The inequality results in true after putting x=-10 so -10 is the solution of inequality.

<u>II. 5</u>

Putting 5 in the inequality

-10>3x-6\\-10>3(5)-6\\-10>15-6\\-10>9

The equality doesn't hold true for x=5 so 5 is not the solution of the problem.

<u>III. -1</u>

Putting -1 in the equation

-10>3x-6\\-10>3(-1)-6\\-10>-3-6\\-10>-9

Inequality doesn't hold true for x=-1 so it is not the solution of the inequality.

Hence,

"I Only" is the correct answer as only -10 is the solution of inequality.
