Answer:

-0.5x² + 20x + 100

Step-by-step explanation:

Given:

R = 25x - 0.5x²

C = 100 + 5x

P = R - C

Where,

P = profits

R = Revenue

C = Cost

which expression represents her profit in dollars?

P = R - C

R = 25x - 0.5x²

C = 100 + 5x

= 25x - 0.5x² -(-100 + 5x )

= 25x - 0.5x² + 100 - 5x

= -0.5x² + 20x + 100

The expression which represents her profit in dollars is -0.5x² + 20x + 100

zysi [14]

Answer:

<h2>x = \frac{y - 3}{4}</h2>

Step-by-step explanation:

y = 4x + 3

To make x the subject send 3 to the other side of the equation

That's

4x = y - 3

<u>Divide both sides by 4 to make x stand alone</u>

\frac{4x}{4}  =  \frac{y - 3}{4}

We have the final answer as

x = \frac{y - 3}{4}

A software firm survey of 595 randomly selected adults showed that 38​% of them would erase all of their personal information on
algol [13]

Answer:

a. \ p=0.38\\\\b. \ \ H_o:p=0.38\\\ \ \ \ \\H_A:p\neq 0.38

Step-by-step explanation:

a. Let, p be the parameter being tested. From the sample, 38% would erase all of their personal information.

-we know that the value of probabilities are in the range [0,1]:

-Given that 38% is the true value of the claim can be symbolically expressed as p=0.5

b. The null hypothesis usually represents the true value parameter under study.

-As stated above, the true value of the parameter is 38%;

-Hence, the null hypothesis is H_o:p=0.38

#Alternative hypothesis is the control value, given the value of the parameter  p=0.38, the alternative hypothesis is that p has a different value other than 0.39:

H_A:p\neq 0.38

Mr. Jones' recipe calls for 1.04 tablets per day. Based on this information, how many tablets should Mr. Jones take per day?
dsp73

Due to the fact that no one can consume .04 of a tablet, we can round down this answer to 1. Even if we were told to round to the tens place, we would still be unable. Remember, 5 or above, give it a shove, 4 or below, let it go. This means that Mr. Jones should take C- 1 tablet per day.

I hope I've helped! :)
