Using PEMDAS you would do the exponent first

2+7 * 12/6 - 3^2=
2+7 * 12/6 - 9=
2+7 * 2 - 9=
9 * 2 - 9=
18 - 9=
9

Hope this helps!!!

The living spaces of all homes in a city have a mean of 2300 square feet and a standard deviation of 500 square feet. Let x be t
antoniya [11.8K]

Answer:

the mean and standard deviation is 2300 and 100 respectively

Step-by-step explanation:

Given that

Mean = 2300

Standard deviation = 500

let us assume the x be the mean of living space

And, the sample is of 25 homes

We need to find out the mean and the standard deviation

So here mean = 2300

And, the standard deviation

= 500 ÷√25

= 500 ÷ 5

= 100

hence, the mean and standard deviation is 2300 and 100 respectively

4. Solve the equation using the quadratic formula.
Vikentia [17]

Answer:

A. x = -2, x = 1.25

Step-by-step explanation:

<u>Use the </u><u>quadratic</u><u> formula</u>

x = \frac{-b+\sqrt{b^{2}-4ac } }{2a}

Once in standard form, <u>identify</u> a, b, and c from the <u>original</u> equation and plug them into the <u>quadratic formula</u>.

4x² + 3x - 10 = 0

a = 4

b = 3

c = - 10

x = \frac{-3+\sqrt{3^{2}-4x4(-10) } }{2x4}

<u>Simplify</u>

<u>Evaluate the exponent</u>

x = \frac{-3+\sqrt{9-4x4(-10)} }{2x4}

<u>Multiply</u> the numbers

x = \frac{-3+\sqrt{9+160} }{2x4}

Add the <u>numbers</u>

x = \frac{-3+\sqrt{169} }{2x4}

Evaluate the <u>square root</u>

x = \frac{-3+13}{2x4}

<u>Multiply</u> the numbers

x = \frac{-3+13}{8}

<u>Separate</u><u> the equations</u>

To solve for the <u>unknown variable</u>, separate into two equations: one with a plus and the other with a minus.

x = \frac{-3+13}{8}

x = \frac{-3-13}{8}

<u>Solve</u>

Rearrange and isolate the <u>variable</u> to find each <u>solution</u>

x = - 2

x = 1.25
