<h3>
12 = -5x/4 - 8</h3>
Multiply both sides of the equation by 4.
<h3>48 = −5x − 32</h3>
Swap the sides so that all variable terms are on the left side.
<h3>−5x − 32 = 48</h3>
<em>Add 32 to both sides.</em>
<h3>−5x = 48 + 32</h3>
<em>Add 48 and 32 to get 80.</em>
<h3>−5x = 80</h3>
<em>Divide both sides by −5.</em>
<h3>x = 80/-5</h3>
<em>Divide 80 by −5 to get −16.</em>
<h3>x= −16</h3>

Answer:
x < -11
Step-by-step explanation:
Let x be the number
- 2x - 2 < -24
- Add 2 to each side, so it now looks like this: 2x < -22
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x < -11
I hope this helps!
Answer:
Step-by-step explanation:
Given that x is a random variable from a binomial distribution with n = 40 and p = 0.9.
We find that mean = np= 36 and variance = npq = 3.6
Std dev = square root of variance = 1.897
When we approximate binomial to normal we say
X' is Normal with mean = 36 and std dev = 1.897
X' is N(36, 1.897)
Note:
The condition for binomial approximating to normal is p should be close to 1/2
Here p is 0.9 and also nq=4 is very small.
So normal approximation may not give accurate results.
The question is wrong since population is not counted in points . for question like these use formula :P(1+R/100)^t where p is current population,r is rate and t is time.
