6. Cross product: A= (2,3,4) B= (2,4,6)

alexgriva [62]

Answer:

(2,-4,2)

Step-by-step explanation:

If this is for Vector Cross Product:

Cross product of two vectors = (u1,u2,u3) * (v1,v2,v3) =

(u2v3 - u3v2, u3v1 - u1v3, u1v2 - u2v1) = ((3*6) - (4*4), (4*2) - (2*6), (2*4) - (3*2) =

(2,-4,2)

How can the probability of an event help make predictions

Sliva [168]

The probability of an event can help make predictions by knowing the chance of something happening and using your knowledge to determine the probability of choosing for example blue on a spinner out of 6 with 4 blues. there is 4 blues and 2 red so you predict it will be on red because there is more of it

What is the value of A when we rewrite 3.14^159x as A^x?

slavikrds [6]

The rule we'll use is

p^(q*r) = (p^q)^r

The exponents have been rearranged a bit.

In this case, p = 3.14, q = 159 and r = x, so,

p^(q*r) = (p^q)^r

3.14^(159*x) = (3.14^159)^x

This is in the form A^x with A = 3.14^159

There are 12 students in a classroom, including the triplets Joey, Chloe, and Zoe. If 3 of the 12 are randomly selected to give

lesya692 [45]

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

P=size of the event space/size of the sample space

step 1

find the probability that Joey will be first

size of the sample size=12

size of the event space=1

P=1/12

step 2

find the probability that Chloe will be second

size of the sample size=12-1=11

size of the event space=1

P=1/11

step 3

find the probability that Zoe will be third

size of the sample size=11-1=10

size of the event space=1

P=1/10

step 4

Find the probability that Joey will be first, Chloe will be second, and Zoe will be third

P=(1/12)*(1/11)*(1/10)-----> P=1/1320-----> 0.00075------> 0.076%

the answer is

the probability that Joey will be first, Chloe will be second, and Zoe will be third is 0.00075 (0.076%)
