Answer:
1/8
Step-by-step explanation:
The least common multiple of 6, 8, and 3 is 24. That will be the common denominator:
1/6 +5/8 -2/3
= 4/24 +15/24 -16/24
= (4 +15 -16)/24 = 3/24
= 1/8
_____
<em>Alternate solution</em>
You can take advantage of the commutative property of addition and the distributive property to rewrite the problem as ...
5/8 -(2/3 -1/6)
= 5/8 - (4/6 -1/6) . . . . use a common denominator of 6
= 5/8 -3/6
= 5/8 =1/2 . . . . . . . simplify
= 5/8 -4/8 . . . . . . use a common denominator of 8
= 1/8

Answer:
C. 68 is your answer.
Step-by-step explanation:
What you do is you take 25 and 52 and times them together.
<em>25 x 52 = 1,300</em>
You will take 1,300 and divide it by 88,400 to get your answer.
<em>88,400/1,300 = </em>
C. 68 is your answer.
Answer:
The options given in the question are incorrect , the correct options are:
a. - 1.645 b. -2.066 c. -2.000 d. -1.960
The test statistic to see whether the proportion is below the requirement is c. -2.000.
Step-by-step explanation:
p= 24/64 = .375
π0= .50
zcalc= (0.375 - 0.50)/[(0.50)(1 - 0.50)/64]
= -2.000
<h3>
Answer: Choice D. 8:9</h3>
Work Shown:
16 boys: 18 girls
16:18
16/2:18/2
8:9
I divided both parts of the ratio by the GCF 2 in order to reduce from 16:18 to 8:9. For every 8 boys there are 9 girls.
