Answer:
Jack must Answer minimum 28 question correctly in order to get A in Science.
Step-by-step explanation:
Given:
Percentage required = 92%
Total Number of question = 30
We need to find the number of Question answer correctly.
Solution:
number of Question answer correctly be 'x'
So we can say that;
number of Question answer correctly divided by Total Number of question multiplied by 100 should be greater than or equal to percentage required.
framing in equation form we get;
Now Dividing both side by 
we get;
Hence Jack must Answer minimum 28 question correctly in order to get A in Science.
ANSWER
The value of theta in the second quadrant is,
EXPLANATION
The given trigonometric equation is
This implies that,
This implies that the principal solution is
and it is an angle in the first quadrant.
But the solution we are looking for is an angle in the second quadrant.
This is given by
Answer:
6 years 4 months
Step-by-step explanation:
2 yrs+3yrs=5+1= 6
6m+10m= 16
There are 12 months in a year so 16-12=4. Add 1 more year to 5 and your left with 4 months.
If the p-value is greater than the level of significance (alpha), then you fail to reject the null hypothesis (H0). This is like saying we don't have enough evidence to reject the null hypothesis so we effectively accept it for now.
Answer is choice B) fail to reject the null hypothesis
Ok, so from previous question
(x-h)^2=4p(y-k)
distance from focus to directix is 2
2/2=1=p
1>-1
focus is above the vertex
1 unit down from (0,1) is (0,0)
vertex at (0,0)
since focus is above, p is positive
(x-0)^2=4(1)(y-0)
x^2=4y
4y=x^2
divide both sides by 4
y=(1/4)x^2
f(x)=1/4x^2
2nd one is answer
