Answer:
a) Eva will need 2 bags of clay to make both pieces of pottery.
b) She will have leftover 
pounds of clay.
Step-by-step explanation:
Hi
a) We have to find the total amount of clay, as she needs 
and 
, so 
, is the total amount of clay. Then as we Know that one bag of clay has 
, It isn´t enough, but with two bags 
, It is enough clay.
b) She will have leftover 
of the second bag, then we add the third one, so 
are leftover.
If 70% lay eggs, that leaves the remaining 30% to give live birth. 2700(0.30) = 810 species
First we need to write the null and alternate hypothesis for this case.
Let x be the average number of text message sent. Then
Null hypothesis: x = 100
Alternate hypothesis: x > 100
The p value is 0.0853
If p value > significance level, then the null hypothesis is not rejected. If p value < significance level, then the null hypothesis is rejected.
If significance level is 10%(0.10), the p value will be less than 0.10 and we reject the null hypothesis and CAN conclude that:
The mean number of text messages sent yesterday was greater than 100.
If significance level is 5%(0.05), the p value will be greater than 0.05 and we cannot reject the null hypothesis and CANNOT conclude that:
The mean number of text messages sent yesterday was greater than 100.
