Answer:
x+x+1+x+2+x+3=190
4x+6=190
4x=184
x=46
Step-by-step explanation:
the numbers are 46&47&48&48
so your answer is 48
Answer: C. The housecats' weights have a higher mean and are more consistently centered around their mean.
Step-by-step explanation:
if we were being more technical then he would be correct because the house cats have a higher mean than the smaller dogs.
SD= 9.9
HC= 11
so the house cats have a higher mean than the smaller cats, in addition has a more consistent mean then smaller dogs due to the range of the lowest in the highest number.
|2x - 10| = -3x
Open absolute value symbol
2x - 10 = 3x
OR
2x - 10 = -3x
x = -10
OR
x = 2
Plug them in...
|2(-10) - 10| = -3(-10)
30 = 30
x = -10 is not the extraneous solution.
|2(2) - 10| = -3(2)
6 ≠ -6
x=2 is the extraneous solution.
Have an awesome day! :)
<span>Write the quadratic function in the form:
f(x) = a(x-h)</span>²<span> + k
Given Function:
f(x) = 3x</span>²<span> + 18x + 28
Using the completing square method:
</span> f(x) = 3(x² + 6x + 28/3)
f(x) = 3(x² + 6x + (3)² - (3)² + 28/3)
f(x) = 3[(x+3)² - (3)² + 28/3]
f(x) = 3[(x+3)² - 9 + 28/3]
f(x) = 3[(x+3)² - 27/3 + 28/3]
f(x) = 3[(x+3)² - 1/3]
f(x) = 3(x+3)² - 1
Therefore,
The vertex is (h,k) = (-3,-1)
