The first one is quadratic function
Force = mass * acceleration
Force = 40 kg * 10 m/s² = 400 N
A) True.
Answer:
80
Step-by-step explanation:
Using this as a guide,
Number of Registered voters = 60
Number of non registered voters = 40
Total number of women in sample is 80
Total number of men in sample is 20
Thus, the expected frequencies for female registered voters
= (80/100)*60
= 48
Expected frequency for female non registered voters is
= (80/100)*40
= 32
Therefore, the total number of females for the expected frequencies is
48+32 = 80
Answer:
66.28% of students study more than 8 hours
Step-by-step explanation:
The percent of students study more than 8 hour can be calculated as
P(X>8)=?
P(X>8)=P((X-mean)/sd>(8-9.92)/4.54)
The calculated z-score is -0.42.
P(X>8)=P(Z>-0.42)
P(X>8)=P(0<Z<-0.42)+P(0<Z<∞)
P(X>8)=0.1628+0.5=0.6628.
Thus, 66.28% of students study more than 8 hours.
