During a week:
Kevin works 3z during 5 days
kevin work (4z-7) during 1 day.
Kevin work 0 during 1 day.
z=unit time
f(z)= number of hours kevin works in one week.
f(z)=5(3z)+(4z-7)+0
f(z)=15z+4z-7
f(z)=19z-7
The number of hours kevin woirs in one week in terms of z is:
f(z)=19z-7
Answer:
Ye cs they're both cong.
Step-by-step explanation:
My understanding is that when the power is a negative number, move it to the denominator and change it to positive.
In this case, the base is y, the power is -3
y^(-3)=1/(y^3)

Answer:
It appears that there ▼ is is not sufficient evidence to conclude that pregnant women can correctly predict the gender of their baby.
Step-by-step explanation:
The results occur by chance.
There's not enough evidence to show that the pregnant women can predict the gender of the babies. 0.327 probability of getting such sample results by chance means 1-0.325 = 0.675 women are unable to predict the gender.
This 0.675 tells us that more than 67 % of the women are unable to predict the gender.
The other option is incorrect .
The probability shows that the sample results ▼ could not have easily occurred by chance.
The probability does not show how the sample results are affected by chance. There' s no increase in the number of trials , there's no evidence of how they guessed.
