Answer:
C
Step-by-step explanation:
If you used the inequality in C, b being able to be as high as -23, it would make 72 is greater than or equal to 72, which is true.
Answer:
80
Step-by-step explanation:
7-(5-3(2+6(2^2)))
When a question has multiple signs, the rule of BODMAS is used. That is, Bracket Of Division Multiplication Addition and Subtraction. The question above will therefore be solved in that order.
The first bracket, we have 2^2
That gives 4
Rewriting the question will give
7-(5-3(2+6(4)))
The question in the next bracket will follow
(2+6(4))
In this bracket too, we have the plus sign and the multiplication sign, so the multiplication will first be solved, them addition will follow.
(2+24)
(26)
Rewriting the question again, we have
7-(5-3(26))
And then, we have the last bracket
(5-3(26))
But we have both the Subtraction sign and the Multiplication sign in this bracket also, so the multiplication will first be solved, before the Subtraction.
(5-3(26))
(5-78)
(-73)
And lastly we have
7-(-73)
7+73
80
She has 52 card all together so she has a probability of drawing on the first draw 4 L's or R's because their are two sets of alphabet cards. So that is 4/52 or 1/13 to the lowest term. Second turn she only has 51 cards to draw from and still has 4 L's and R's so that would be 4/51 and on the third try she has only 50 cards left so that would be 4/50 or 2/25 to the lowest term. Now multiply all three factions 1/13 x 4/51 x 2/25 = 8/16575 meaning out of the three draws she has a probability of getting a L or R, 8 out of 16575 each draw.
Answer:
3 out of 7
Step-by-step explanation:
you just simplify the expression divide it by 2 on both side and it ends up to 3 out of 7
has gradient
which at the point (-1, 4, 3) has a value of
I'm not sure what the given direction vector is supposed to be, but my best guess is that it's intended to say 
, in which case we have
Then the derivative of at (-1, 4, 3) in the direction of 
is
