Answer:
95%
Step-by-step explanation:
About 95% of the area is within two standard deviation in standard normal distribution. This can be explained by finding the probability within 2 standard deviation using standard normal distribution.
P(z1<Z<z2)=P(-2<Z<2)
P(-2<Z<2)=P(-2<Z<0)+P(0<Z<2)
P(-2<Z<2)=0.4772+0.4772
P(-2<Z<2)=0.9544
Thus, About 95% of the area is between z2 and z2
Answer:
2 1/2
Step-by-step explanation:
If you do the step by step calculation:
Step 1: Simplify both sides of the equation.
2(12+2x+15+2x)=74
(2)(12)+(2)(2x)+(2)(15)+(2)(2x)=74(Distribute)
24+4x+30+4x=74
(4x+4x)+(24+30)=74(Combine Like Terms)
8x+54=74
8x+54=74
Step 2: Subtract 54 from both sides.
8x+54−54=74−54
8x=20
Step 3: Divide both sides by 8.
8x divide by 8 and that is 20 divided by 8
leaves you with the answer 5/2.
If you then turn the improper fraction into a mixed fraction you get 2 and one half.
