Evaluate the dot product of (2 4) and (1 -2)

Mathematics

Aneli [31]3 years ago

I'd suggest writing this as

<2, 4> dot <1, -2>.  Another name for this is "scalar product."

Rule:  <a,b> dot <c,d> = ac + bd

Thus, 

<2, 4> dot <1, -2> comes out to (2)(1) + (4)(-2) = -6 (which is a scalar).

sattari [20]

Answer:

ok so here we know that Baily kicked the target 6 times out of 20 that  is 6/20 and then you just reduce the fraction dividing it by 2 so it will be  3/10

You roll a 6-sided die two times. What is the probability of rolling a 4 and then rolling a 2? (Write your answer as a fraction
Delicious77 [7]

Answer:

1/36

Step-by-step explanation:

On the first throw, the probability of rolling any particular number, 1 through 6, is 1 out of 6. So the chance of rolling a 4 is 1/6.

On the second roll, your probability of rolling a 2 is 1/6.

The 'trick' is knwoing what to do with those two numbers.

Here's the rule: If events are dependent on one another, you multiply the probabilities.

Any time you see a scenario where X has to happen <u>and then </u>some other thing (X, Y, or whatever) has to happen, the events are dependent.

Probability of rolling a 4 <u>and then</u> rolling a 2 = 1/6 * 1/6 = 1/36

Hope this helps.

Write the equation in standard form. Identify the important features of the graph:
Lerok [7]

Answer:

Standard form: \left(x-\dfrac{9}{2}\right)^2+(y+5)^2=\dfrac{121}{4}.

This equation represents the circle with the center at the point \left(\dfrac{9}{2},-5\right) and the radius r=\dfrac{11}{2}.

Step-by-step explanation:

Consider expression x^2+y^2-9x+10y+15=0.

First, form perfect squares:

(x^2-9x)+(y^2+10y)+15=0,\\ \\\left(x^2-9x+\dfrac{81}{4}\right)-\dfrac{81}{4}+(y^2+10y+25)-25+15=0,\\ \\\left(x-\dfrac{9}{2}\right)^2+(y+5)^2=10+\dfrac{81}{4},\\ \\\left(x-\dfrac{9}{2}\right)^2+(y+5)^2=\dfrac{121}{4}.

This equation represents the circle with the center at the point \left(\dfrac{9}{2},-5\right) and the radius r=\dfrac{11}{2}.

Chris Paul makes his free throws 88% of the time what is the probability of Chris Paul making all of his next 9 free throws
Semenov [28]
So with that data we can say 88% of 9 of his shots will go in. That number is probably going to be a decimal so we'll round up. 0.88 x 9 = 7.92. You can't make a hundredth of a free throw shot so let's round up to 8 a whole number. The theoretical probability that Paul will make his next nine shots is 8/9.
