Try this option:
1) if V(0;0) and x= -4, then common view of the required equiation is:
(y-k)²=4p(x-h), where focus is in (h-p;k), the vertex is in (h;k), the directrix is x=h+p, p<0 and y=k is simmetry axis;
2) if the V(0;0), then h=k=0 and the required equiation is:
y²=4px;
3) if the directrix equation is x=h+p, where h=0, then p= -4 (according to the condition the directrix equation is x= -4), then the required equation is:
y²= -16x
answer: y²= -16x
You use the formula a² +b² =c²
so 4² +b² =8²
solve for b
The <em>correct answer</em> is:
The mean for July is smaller than the median; and
the mean for August is larger than the median.
Explanation:
A distribution with a positive skew would have a longer whisker in the positive direction than in the negative direction. A larger mean than median would also indicate a positive skew.
Alternatively, a distribution with a negative skew would have a longer whisker in the negative direction than in the positive direction. A smaller mean than median would also indicate a negative skew.
The whisker in the negative direction for July is longer than the whisker in the positive direction. This indicates a negative skew.
The whisker in the positive direction for August is longer than the whisker in the negative direction. This indicates a positive skew.
Your answer would be 12.
She can use 12 connecting cubes to make the model in only two ways.
As we can see, the number 3999991 can be expressed as a product of two numbers that are not 1 and the number 3999991 itself, therefore that number is not prime.
