I think Its C because in the frequency table or table given if the heads are counted there are 6 of them and over all 10 which will make 6/10
Answer:
1 and 3 is right and I’m pretty sure 2 is right also.
Step-by-step explanation:
The answer is the first option, <-20, -42>.
We can find this by first finding what -2u would equal by multiplying <5, 6> by -2. This gives us <-10, -12>.
Then we need to find out what 5v is equal to, by multiplying <-2, -6> by 5 to get <-10, -30>.
Now that we know what -2u and 5v are, we can substitute them into the equation and get
<-10, -12> + <-10, -30>, which we can split up into -10 - 10 = -20, and -12 - 30 = -42, so your final answer is <-20, -42>.
