I CALCULATED IT AND GOT
C) 4.29
The answer is
f(x) = 9x3 + 18 x2 - 135x can be written as f(x) = x( 9x2+ 18 x - 135)
the first zero must be = 0
let's find the another zeros by solving 9x2+ 18 x - 135=0
f(-5)=135-135=0, so the answer is
<span>
0, -5, and 3
because </span><span>f(x) = 9x3 + 18 x2 - 135x =x (x+5)(x-3)</span>
Answer:
91
Step-by-step explanation:
you add the numbers that are in the () then you times those two numbers together and you will get the answer
Answer:
A.
1.125%; 0.375%
Step-by-step explanation:
Quarterly interest rate is 4.5 / 4 = 1.125%.
Monthly rate is 4.5 / 12 = 0.375%.
The researcher's scientific/alternative hypothesis is:
- Different sources of caffeine leads to differences in women's attentional control performance.
The researcher's null hypothesis is:
- Different sources of caffeine leads to no difference in women's attentional control performance.
The type of sample which the researcher is using is:
A disadvantage to using this sample type is:
The thing which the researcher can conclude about these data is:
- It is conclusive based on the reaction of the women to the independent variables.
If, in the population, women actually show NO difference in attentional control performance after drinking black tea versus coffee, the type of statistical error which the researcher has made is:
<h3>What is a Scientific Hypothesis?</h3>
This refers to the difference between two variables which is discovered during a scientific research and is an observed pattern.
