Answer:
AB = 4
BC = 4
AC = 8
Step-by-step explanation:
Given, B is the midpoint of AC which means it divided the AC into two equal parts. Using this information we can write the following equation:
5x - 6 = 2x add 6 to both sides
5x = 2x + 6 subtract 2x from both sides
3x = 6 divide both sides by 3
x = 2 to find the length of AB, AC, and BC replace x with 2
AB = 5*2 - 6
BC = 2*2
AC = 8 (sum of AB and BC)
Answer:
0.1
Step-by-step explanation:
Answer: 40%
Step-by-step explanation:
Let the percentage of 22 that gives 8.8 = x% ---------------------------1
Therefore,
x% of 22 = x/100 x 22 ------------------2
since this gives 8.8, we now equate to equation 2
x/100 x 22 = 8.8
(22 x X )/100 = 8.8
22x/100 = 8,8
Now cross multiply to solve for x
22x = 8.8 x 100
22x = 880
Now divide through by 22 to get the require value of x
x = 880/22
x = 40%
Answer:
Step-by-step explanation:
(One tailed test at 5% significance level)
Sample size =200 and sample proportion =
Std error of p = 
Test statistic = p diff/std error = -2.89
p value = 0.001926
So we reject H0 and accept alternate hypothesis.
