Answer:
the probability that two 18 year old boys chosen at random will have heights greater than 185cm is 0.403
Step-by-step explanation:
P( x > 193) = 0.15
= 1- p(x less than or equal 193)
= 1 -p( z < (x- u) /sigma)
= 1- p( z< (193 - 187)/ sigma)
= 1- p( z< 6/ sigma)
P(z< 6/sigma) = 1 - 0.15
P(z < 6/sigma)= 0.85
6/sigma =1.036
Sigma= 6/1.036
Sigma= 5.79
P( x> 185) = 1- p( x< 185)
= 1- p (z < (185- 187)/5.79)
= 1- p( z< -0.345)
= 1- 0.365
= 0.635
P (x> 185) = 0.635 × 0.635
=0.403
8 x 64
=64 x 2 x 4
=128 x 2 x 2
=256 x 2
=512
Answer:
Melissa picked 16 apples
Step-by-step explanation:
(Eric and Stephanie) 160 divided by 10 (I put ten because I add 6 and 4)
Which will equal 16.
Hope this helps ~~~~ :)
16= 32 =48. 72- 48 = 24. The third side of the triangle is 24! Hope this helps, have a great day! :)
I have no idea, i just have to answer a question i’m sorry
