Answer:
B) y = 129º
Step-by-step explanation:
since a triangle is 180º in total, the you have to subtract 71 and 58 from 180 which will give you 51º which gives you the amount for x
and the line that the triangle is on is also 180º in total, so you subtract the 51 from 180 to give you a total of 129º which is the amount for y
The answer is: " 1024π units² " ; or; " 3215.36 units² " .
______________________________________________________
A = π * r² ;
A = π * 32² = 1024 π units² ;
or, using "3.14" for "π" ;
1024 * π = 1024 * (3.14) = 3215.36 units² .

Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The sample size is
The proportion that choose to vaccinate the teen boys is
considering the first statement
The 95% confidence interval is 12% ± the margin of error*standard deviation is false because
The 95% confidence interval is is %12 ± the margin of error
considering the second statement
The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem
np = 64 * 0.12 = 7.68
and this value is less than 10 hence the confidence interval should not be calculated
considering the third statement
A 99% confidence interval will be smaller than the 90% confidence interval is false
This is because as the confidence level increase (for example from 90% to 99%) the margin of error increase which increases the confidence interval
-10x+4.
5x-7x is -2.
-2x-8x is -10x.
you cannot simplify the 4
alternatively, you could write -10x+4 as
-2(5x-2)
To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.
