Hi there! :)

A radical equation is an equation in which a variable (ex. x, y, a, v) is under a radical sign. The only equation that has a variable under a radical (x) is the second option. There is an x next to the 2 under the radical.

I hope this helps, DM me if you have anymore questions. :)

The diameter of a spindle in a small motor is supposed to be 4.1 millimeters (mm) with a standard deviation of 0.1 mm. If the sp

adoni [48]

Answer:

The null hypothesis is $H_0: \mu = 4.1$

The alternate hypothesis is $H_a: \mu \neq 4.1$

Step-by-step explanation:

The diameter of a spindle in a small motor is supposed to be 4.1 millimeters

This means that the null hypothesis is that the diameter has the supposed value, that is, $H_0: \mu = 4.1$

If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 41 spindles to determine whether the mean diameter has moved away from the required measurement.

Tests if it has moved away, that is, if the mean is different from the specified value of 4.1. So the alternate hypothesis is $H_a: \mu \neq 4.1$

How do I Simplify 4+9x2÷3-1

Lunna [17]

Step-by-step explanation:

Step 1: Simplify

$4+9x^2/3 - 1$

$=4+3x^2+-1$

Step 2: Combine Like Terms:

$= 4+3x^2+1-1$

$= (3x^2)+(4+-1)$

Answer: $= 3x^2+3$

Explanation in words (Short Form)

- The first step is to use the formula and simplify it. So first we will Rewrite the division as a fraction.

- The second step is to Cancel the common factor of 9 and 3. Then Factor 3 out of 3. After that Cancel the common factor.

- The third step is to divide $3x^2$ by 1. Then at the end, subtract 1 from 4. The answer will result as $3x^2+3$

Answer:

$=3x^2+3$

Hope this helps.

Multiply all terms by 2 to get rid of fractions
2x+10=28-x

Add x to both sides
3x+10=28

Subtract 10 from both sides
3x=18

Divide both sides by 3
x=6

Final answer: x=6
