Explanation:
Consider ...
x/a = b/c . . . . . find x
Multiplying by the denominator under x gives ...
x = ab/c . . . . the value of the unknown.
____
In the case where the unknown is in the denominator, you can invert the ratios and solve as above:
a/x = c/b . . . . . note that x is in the denominator
x/a = b/c . . . . . equivalent equation, solve as above
Answer:
The exact value is -3f
Step-by-step explanation:
The other endpoint is (31, -4)
<em><u>Solution:</u></em>
Given that midpoint (23,- 10), endpoint (15.-16)
To find: The other endpoint
<em><u>The formula for midpoint is given as:</u></em>
Here in this problem,
<em><u>Substituting the values in formula we get,</u></em>
On comparing both sides we get,
Thus the other endpoint is (31, - 4)
Answer:
80% of the students would vote for Tammy
Step-by-step explanation:
Since a Kimberly took a sample of 30 students from the school and it was found that 24 students said they would vote for Tammy. To determine Kimberly's best estimate of the number of students in the school who would vote for Tammy, we divide the number of students that said they would vote for tammy by the total number of student sample.
number of students who would vote for Tammy = students who said would vote for sammy / number of sample = 24 / 30 = 4/5 = 80%
Answer:
Step-by-step explanation:
Let X be the solvent present
Then given that the manufacturer of industrial solvent guarantees its customers that each drum of solvent they ship out contains at least 100 lbs of solvent.
X is N(101.3, 3.68)
a)
Probability = 0.6368
b) means Z score = 1.88
X=100+1.88(s) =101.3
s=1.3/1.88=0.6914
