Answer:
68 degrees
Step-by-step explanation:
This triangle is an isosceles triangle which means that two sides have equal lengths and when two sides have equal lengths that means that two angles are the same. so you add 56 and 56 together and you get a sum of 112. all triangles add up to a degree of 180, so you therefore subtract 112 from 180 which gives you an answer of 68 degrees , therefore x is 68
Answer:
13 students were fed
Step-by-step explanation:
now first in order to count we will have to turn 3 1/4 into a whole number which means we will have to multiply the denomintor by 3 and add it to the numerator which is 1
4 x 3= 12 ..... 12 + 1 = 13
13/4 and the denominator always stays the same
and now to count we will have to divide 13/4 divided by 1/4
now instead of dividing you can just multiply them by switching the denominator and numerator 1/4 to 4/1
13/4 x 4/1
52/4
13

Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
Given :
n=23, which is a small sample(n<30), so we use t-test.
Significance level:
Critical value :
Then , the confidence interval for population mean will be :-
Hence, the 95% confidence interval for the population mean is
