X-2=6x+18
-x -x
-2=5x+18
-18 -18
-20=5x
x=-4
Simply change 1/4 to a decimal
1/4 = 0.25
now we can multiply 0.25 and 32
lets do the math:)
0.25 x 32 = 8
your answer = 8
When in doubt, eat a pineapple :)
Answer:
0.89736
Step-by-step explanation:
We solve this question using z score formula
Z score = x - μ/σ
x = raw score
μ = population mean
σ = population standard deviation
Hence,
x = 258, μ = 220, σ = 30
Z = 258 - 220/30
=1.26667
Probability value from Z-Table:
P(x<258) = 0.89736
Therefore, the probability that his weights is less than 258 kg is 0.89736
