Answer:
X=2
Step-by-step explanation:
9x+1=2x+15
1. restar 1 de ambos lados ejemplo: 9x+1-1=2x+15-1
2. simplificar Ejemplo: 9x=2x+14
3. restar 2x de ambos lados ejemplo: 9x-2x=2x-2x+14
4. simplificar ejemplo: 7x=14
5.divide ambos lados entre 7 ejemplo: 7x/7= 14/7
6.Simplificar ejemplo: x=2
Answer:
0.13
Step-by-step explanation:
Answer:
its 4
Step-by-step explanation:
Because since the next number is 8 and its above 5 then a number above 9 is something you cannot put in so you just round the whole number since the rest of the numbers are also 9.
When talking about object measurements, we usually require they be positive.
A suitable domain is x > 0.
(and somewhat less than any substantial fraction of the Earth's dimensions. The numerical value will depend on the chosen units.)
Answer:
There is not sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 level of significance
Step-by-step explanation:
H0: sigma= 66%
Ha:sigma < 66%
Chi square =(28-1)*2.82^2/66^2=0.049
p value =0.286
as p value>0.01 we do not can reject H0
So there is not sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 level of significance
