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.
Answer:
13:35 (01:35)
Step-by-step explanation:
60-13= 47
6:47
+6:48
∴ Add 48 and 47 = 95 mins
so, 95- 60= 35 mins
The extra 60 mins (1 hr) is added to the hours on the left.
so, 6+1= 7 and then 7+6 = 13
∴ 13:35 pm , which can also be written as 01:35 pm in 12-hr-clock format.
Answer:
B
Step-by-step explanation:
A constant variation graph has the following format:
Where k is the constant of proportionality.
Let's pick a point from the graph, say, (1,5).
Substitute 1 for x and 5 for y:
Simplify:
Therefore, the constant of proportionality is 5.
And we're done!
