Answer:
9x3 – 8x2
Step-by-step explanation:
Simplify signs:
8x2 - 5x3 - 4x2 + 9x3
Combine like terms:
(8x2 - 4x2) + (9x3 - 5x3)
Answer:
For this case we can make the following rule of three:
25% ----------------> 2 $
100% --------------> x
From here, we clear the value of x.
We have then:
Therefore, the value of the Taco that Andrea bought, before the tip, is $ 8.
the price of Andrea's tacos, before tip is $ 8.
Answer:
The approximate probability that more than 360 of these people will be against increasing taxes is P(Z> <u>0.6-0.45)</u>
√0.45*0.55/600
The right answer is B.
Step-by-step explanation:
According to the given data we have the following:
sample size, h=600
probability against increase tax p=0.45
The probability that in a sample of 600 people, more that 360 people will be against increasing taxes.
We find that P(P>360/600)=P(P>0.6)
The sample proposition of p is approximately normally distributed mith mean p=0.45
standard deviation σ=√P(1-P)/n=√0.45(1-0.45)/600
If x≅N(u,σ∧∧-2), then z=(x-u)/σ≅N(0,1)
Now, P(P>0.6)=P(<u>P-P</u> > <u>0.6-0.45)</u>
σ √0.45*0.55/600
=P(Z> <u>0.6-0.45)</u>
√0.45*0.55/600
0.51 grams is < 0.482, thus Maurice has more salt.
