Just remember to do PEMDAS
P,parentheses do what's in them first
E, exponent do what's in them 2nd. for M & D you just do multiply or divide whatever one comes 1st
for A & S then add and subtract you don't have
to do add at first it's just what come first.
hoped that helped

Nata [24]

Answer:

<u>The correct answer is D. 53x - 12</u>

Step-by-step explanation:

Let's find P(x), this way:

Profits = Revenue - Cost

Profit function = Revenue function - Cost function

P (x) = R (x) - C (x)

Replacing with the real values we have:

P (x) = 60x - (12 + 7x)

P (x) = 60x - 12 - 7x

P (x) = 53x - 12

<u>The correct answer is D. 53x - 12</u>

I don’t get this :(

Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)


So first we need to convert the mixed number to an improper fraction


1 4/5 = 9/5


Now we need to reduce the numbers greatest common divisor which is 3

3/5 x 6

Now multiply the numbers


Your answer is 18/5 I hoped this help



Now for the second one

this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21


The last one is the same steps we did for the first one which is 27/20



I hoped this helped you it is a little difficult but you’ll get the hang of it :)

PLEASEE HEEELP! In the normal distribution, 68% of the data lies within 1 standard deviation A: __/6 of the mean, 95% of the dat
Lena [83]

Answer:

a) 2.5% b) 50%

Step-by-step explanation:

1300 is two standard deviations higher than the mean. Since 95% of the data is covered within two standard deviations to the left and right of the mean, 5% is not covered. So, we have 2.5% leftover on the left side of the curve, under 900, and 2.5% leftover on the right side of the graph that is above 1300.

The mean is 1100, so anything above or below the mean is exactly 50% in a normal distribution.
