You need to use y=mx+c to answer this so basically
gradient/slope (m) is 1.5 and the y-intercept (c) is -2
Hope this helps :)
Answer:
3xy
Step-by-step explanation:
These terms are all like terms so you can add:
-2xy + 2xy = <em>0xy</em>
Now add 3xy + 0xy: 3xy
Answer: 151
Step-by-step explanation:
When the prior estimate of population proportion is available , then the formula for sample size: 
, where p= prior estimate of population proportion
z*= critical-value.
E= Margin of error.
Let p be the proportion of of girls "wait for their missionary".
p = 11% =0.11
E= ± 0.03
The critical z-value corresponding to 90% confidence level = z*=1.645 [using z-table ]
Substitute all the values in the above formula , we get
Required sample size :

[Rounded to next integer.]
Thus, the number of observations he needs in his sample = 151
"Product" means to multiply, so you have to multiply 379 by 8 to get 3,032; it's between the numbers 3,031 and 3,033
