It seems appropriate to use the linear regression function of your calculator for this. Looking at the data, you know the slope is generally positive, so only the 1st and 3rd choices are potentially viable.
A calculator shows the correlation coefficient (r) rounds to 0.816, so the appropriate selection is ...
A. 0.816
D
divide both sides of the function by πx to get y=a/(πx)
–2x<span> + 6. (</span>f<span> – </span>g)(x<span>) = </span>f<span> (</span>x<span>) – </span>g(x). = [3x + 2] – [4 – 5x]. = 3x + 2 – 4 + 5x. = 3x + 5x + 2 – 4. = 8x – 2. (f<span> × </span>g)(x) = [f<span> (</span>x)][g(x)]. = (3x + 2)(4 – 5x). = 12x + 8 – 15x2<span> – 10x ... of the </span>functions<span> at </span>x<span> = 2 and then work from there. It's probably simpler in this case to evaluate first, so: </span>f<span> (2) = 2(2) = 4. </span>g(2) = (2) + 4 = 6. h(2) = 5<span> – (2)</span>3<span> = 5 – 8 = –</span><span>3</span>
Answer:
it's c
Step-by-step explanation:
4 times 10 times 6 is 240 and you use volume because its by 3 values.
hope this helped!
Answer:
5 days
Step-by-step explanation:
We can use a ratio to solve
12 emails 60 emails
--------------- = --------------
1 day x days
Using cross products
12*x = 1 * 60
12x = 60
Divide each side by 12
12x/12 = 60/12
x =5
It will take him 5 days
