Multiply the numbers
2(2/3)
2/1(2/3)= 4/3 = 1 1/3
Ow... this geometry is sure hard!!
.
Wait a second. Nope.
.
TWO SIDES!!
.
ITT!!
.
CONVERSE ITT!!
.
Converse Isosceles Triangle Theorem!
.
Look at the picture I attached.
.
Two angles equal... THE SIDES ADJACENT TO IT EQUAL!!
.
PERFECTO!!
.
Hope I helped!!

Answer:
95% Confidence interval = (23.4,26.2)
Step-by-step explanation:
In this problem we have to develop a 95% CI for the mean.
The sample size is n=49, the mean of the sample is M=24.8 and the standard deviation of the population is σ=5.
We know that for a 95% CI, the z-value is 1.96.
The CI is
12/7 + 8/7
12+8 = 20
20/7 = 2 and 6/7ths
(Add5) 1/9..(add 7) 1/16... (add9) 1/25... (add 11) and get -> 1/36
