Answer:
8b- 13 6/7
Step-by-step explanation:
A product of 8 and b just means 8 x b or 8b.
13 6/7 less than that product means subtraction.
Therefore, it would be 8b -
(y - yo) = m.(x - xo)
We have the points (4, 12) and (x, 18) with slope of 3.
(18 - 12) = 3.(x - 4)
6 = 3x - 12
3x = 6 + 12
3x = 18
x = 18/3
x = 6
Answer:
The composite function;
f(g(x) = 2x^2 + 15
Step-by-step explanation:
Given f(x) = 2x + 1 and g(x) = x^2 + 7 ;
we want to find f(g(x))
This is simply a composite function which involves fixing the function g(x) into f(x)
Thus, we have
f(g(x)) = 2(x^2 + 7) + 1
f(g(x)) = 2x^2 + 14 + 1
f(g(x)) = 2x^2 + 15
Answer:
only 1/4 produces a rational number when added to 0.5.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that for a sample of size n = 13, mean =122 and std dev = 13
STd error of sample =
Hypotheses:
(One tailed test at 5% sign level)
Mean difference = 1 and test statistic
df = n-1 =12
pvalue = 0.3929
Since p > alpha, accept null hypothesis
There is no evidence to prove that mean is greater than 121.
