Answer:
A, C, D and K
Step-by-step explanation:
First, plot the solution set to the system of two inequalities.
The inequality 
determines solid line and bottom shaded region under this line.
The inequality 
determines dotted line and top shaded region under this line.
The intersection of these two regions is the solution set to the system of two inequalities.
Points A, C, D and K belong to this region.
Given function : 
.
We need to find the values of f(-2).
In order to find the value of f(-2), we need to plug x=-2 in the given fucntion .
Replacing x by -2, we get
We get (-2)^2 = -2 *-2*-2=-8 and (-2)^2 = -2 * -2 = 4.
.
f(-2) = -160 +12.
f(-2) = -148.
Therefore, correct option would be option D. That is f(-2)=-148.
the second option
Step-by-step explanation:
root 4 16 is 2
root 4 powers mean divide by 4
Answer:
The weight of sunflower seeds in each snack bag is 1/16 of a pound
Step-by-step explanation:
Here, we want to know the weight of sunflower seeds in each snack bag.
The total weight bought is 9/16 pound and the division is into 9 bags
So the weight of the individual bags will be ;
9/16 divided by 9
= 9/16 * 1/9 = 1/16
Answer:. This would be 0.81^20 for none of the 19=0.0148
Step-by-step explanation:With a tree diagram, there are two possibilities, one is ND from 1 D from 2, with probability (5/8)(2/5)=(1/4) and the other is (3/8)(3/5)=9/40 That would be 19/40 for the answer.
3. Poisson parameter lambda=5
for P(0), it is e^(-5)(5^0)/0! or e^(-5)=0.0067
for P(1), it is e^(-5)(5^1)/1! or 5e(-5)
The total probability is 6e^-5 or 0.0404
4. the mean is 1000 hours, so lambda is the reciprocal or 1/1000
the probability it will last <800 hours is 1-e^(-800*1/1000) or 1-e^(-.8)=0.5507
5. assume p=0.4 since it ca't be 4
sd is sqrt (np*(1-p))=sqrt (6*0.6=sqrt(3.6)=1.90
