Hey there!

<h2>ANSWER: $c=2 \text{ or } c=-2$ </h2><h2>EXPLANATION:</h2>

$c^2=4$

If you are looking to find c, let's see what types 2 equals for.

$c*2=4$

We know a number * 2 = 4. That number is 2. Let's see if c is equal to 2.

$c*2=4\\2*2=4$

The answer is true because 2 * 2 does equal 4. So the answer is $c=2$ .

$c=2$

But the value can be a negative as well because $2^2$ is also equal to 4.

$c^2=4\\-2^2=4\\c=-2$

Hope this helps!

Equations for m equals three times n devided by the difference of 4p and 5 n

MrRa [10]

Numerator of the equation is 3*nDenominator is 4*p - 5*n The equation is m = 3n/(4p-5n)

Numerator = 3*n
Denominator = 4*p - 5*n
Equation = [m = 3n/(4p-5n)]

Use the given values of n= 93 and p= 0.24 to find the minimum value that is not significantly low, μ- 2σ , and the maximum val

allsm [11]

Answer:

The answer is "Option a".

Step-by-step explanation:

$n= 93 \\\\p= 0.24\\\\\mu=?\\\\ \sigma=?\\\\$

Using the binomial distribution: $\mu = n\times p = 93 \times 0.24 = 22.32\\\\\sigma = \sqrt{n \times p \times (1-p)}=\sqrt{93 \times 0.24 \times (1-0.24)}=4.1186$

In this the maximum value which is significantly low, $\mu-2\sigma$ , and the minimum value which is significantly high, $\mu+2\sigma$ , that is equal to:

$\mu-2\sigma = 22.32 - 2(4.1186) = 14.0828 \approx 14.08\\\\\mu+2\sigma = 22.32 + 2(4.1186) = 30.5572 \approx 30.56$

A recipe calls for 5 8 pound of cheese per batch. Assuming you have enough of the other ingredients, how many batches of the rec

aliya0001 [1]

I assume you mean 5/8 of a pound not 58 pounds. In that case convert your total number of pounds into eights to make it easier to calculate. 5 pounds is equal to 40/8 pounds of cheese. Now divide this by 5/8. That equals 8. SO you can make 8 batches.
