Wouldn't the answer be -23/4
The answer would be $11.8 then just round that up to the nearest whole number which would be $12. Hope this helped if I’m incorrect I apologize:/but I’m pretty sure that’s right!
A^2+b^2=c^2
4 squared and 3 squared =25
square root of 25 is 5
answer is d
Answer: 16
Step-by-step explanation:
From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.
The probability of picking a blue marker will be: = 5/25 = 1/5
Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:
= 1/5 × 80
= 16 times
I hope this helps you
-cos²x= sin²x-1
4.sinx = sin²x-1+4
sin²x-4.sinx +3=0
(sinx-3)(sinx-1)=0
sinx≠3
sinx =1
SİN90=1
