-4 (-2)+3 (4)+3 (-4)-5 (4)

1 answer:

4 0

Due to PEMDAS, you want to start with multiplying the parenthesis. I will group it first so that you can see the grouping easier.

-4(-2) + 3(4) + 3(-4) - 5(4)

Now we multiply the terms together.

-8 + 12 - 12 - 20

As you can see above, there is a positive 12 and a negative 12. These two will cancel out, leaving you with:

-8 - 20

Now you just combine the terms.

This results in a final answer of -28!

The experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

<h3>What is Experimental Probability?</h3>

Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood and each repetition is known as a trial. The experiment is conducted to find the chance of an event to occur or not to occur.

Here , Favorable Outcome = 19

Total outcomes = 20

Probability = Favorable Outcome/ Total Outcome

= 19 / 20

= 95%

Thus, the experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

How does the graph of g (x) = StartFraction 1 Over x + 4 EndFraction minus 6 compare to the graph of the parent function f (x) =

rjkz [21]

The transformed equation $g(x)=\frac{1}{x+4}-6$ , the graph is shifted 4 units to the left and 6 units down.

Explanation:

The parent equation is $f(x)=\frac{1}{x}$

The transformed equation is $g(x)=\frac{1}{x+4}-6$

By using the function transformation rules, we can see that the parent function $f(x)=\frac{1}{x}$ is transformed into the function $g(x)=\frac{1}{x+4}-6$

Since, from the function transformation rules, we know that,

$f(x+b)$ shifts the function b units to the left.

Thus, the transformed function is shifted 4 units to the left.

Also, from the function transformation rules, we know that,

$f(x)-b$ shifts the function b units downward.

Thus, the transformed function is shifted 6 units down.

Thus, the transformed equation $g(x)=\frac{1}{x+4}-6$ , the graph is shifted 4 units to the left and 6 units down.
