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
6 < c < 20,
Of course if you knew the triangle was a right triangle you could use the Pythagorean theorem to directly get the size of the third side.
Answer:
-12
Step-by-step explanation:
3(x-4)+2x^2
when x =5 , sub 5 into x
3(5-4)+2(5)-(5)^2
=15-12+10-25
=-12
Answer: initial Y = 20g
Y as a function of time is in the explanation.
Step-by-step explanation: Please find the attached file for the solution
1,1x + 1,2x - 5,4x = - 10
- 3,1x = - 10
x = - 10 : (- 3,1)
x = - 10 : (- 3 1/10)
x = 10 : 31/10
x = 10 * 10/31
x = 100/31
x = 3 7/31
