Answer:

I think it would be 34 because I divided 68.2 by 4 and got 17.05, so I multiplied that by 2, and it's closest to 34.

So I think it's A.

But y'all don't be mad if I'm wrong cuz I said I think.

Choosing blue or red: 3 blue + 4 red = 7 marbles
3 blue + 2 green + 4 red + 1 yellow = 10 marbles

Probability blue or red marble: 7/10

Choosing a marble that isn't blue or red: 2 green + 1 yellow = 3 marbles
Total marbles: 3 blue + 2 green + 4 red + 1 yellow = 10 marbles

Probability non-blue or red marble: 3/10

Can I get a answer ASAP please I would greatly appreciate it

Answer: A

Step-by-step explanation:

Domain is based off of the x-axis (left to right).

The curve starts at -1, and ends at 3. Therefore, x is greater than, or equal to -1, and x is less than, or equal to 3.

Also note that the dots signifying the beginning and end of the line is filled in (completely black). If the dot was not filled in, that's basically saying that line doesn't include the number the dot is on.

Can someone help me on this

SCORPION-xisa [38]

Step-by-step explanation:

(a) n² + 3

First term = 1² + 3 = 4

Second term = 2² + 3 = 7

Third term = 3² + 3 = 12

Fourth term = 4² + 3 = 19

10th term = 10² + 3 = 103

(b) 2n²

First term = 2(1)² = 2

Second term = 2(2)² = 8

Third term = 2(3)² = 18

Fourth term = 2(4)²= 32

10th term = 2(10)² = 200

Hence, this is the required solution.

A particle starts at the point P=(−1,1,3)P=(−1,1,3) and moves along a straight line toward Q=(−4,4,5)Q=(−4,4,5) at a speed of 7

Answer: (-1,1,-3) + 7 x t x (3,-2,-8)/ $\sqrt{77} \\$

Step-by-step explanation:

The parametric vector equation for the position of particle is given as:

We have P= (-1,1-3)

Q= (-4,4,5)

So PQ vector= (-1+4,1-3, -3-5)

PQ = (3,-2,-8)

Magnitude of this vector= $\sqrt{(3)^2+(-2)^2+(-8)^2}$

Magnitude= $\sqrt{77} \\$

So unit vector= (3, -2, -8)/ $\sqrt{77} \\$

Now the equation is as:

P + 7 x t x unit vector = (-1,1,-3) + 7 x t x (3,-2,-8)/ $\sqrt{77} \\$
