Answer:
Step-by-step explanation:
Given that the time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z<
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
Multiply both sides by negative four to get rid of the fraction
j+18=-32
subtract 18
j=-50

Answer:
0,11
Step-by-step explanation:
y^2-11y=0
y(y-11)=0 we have transformed the equation into a product
a product can be zero only if one of the factors is 0
so the two solutions are
y=0
and y-11=0 y=11
