Answer:
<h2>2x + 3</h2>
Step-by-step explanation:
f(2x) means that we have to substitute x with 2x
So, the answer is
2x + 3
Answer:
D. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric.
Step-by-step explanation:
Hello!
The given frequency distribution for temperatures.
To see if the distribution appears to have a normal distribution you have to draw a histogram using the information. Check attachment.
As you can see, the distribution appears symmetric, it starts low and proceeds to grow until it reaches its maximum point (f(4)=13) and then starts to decrease to low frequencies. The right tail decreases a little more than the left one but it is almost symmetrical.
I hope this helps!
y = - 5
substitute the value of x = 4 into the equation and solve for y
- 12 + 9y = - 57 ( add 12 to both sides )
9y = - 45 ( divide both sides by 9 )
y = = - 5
