find the length of the third side of triangle if its midline measures 45cm
Answers
Answer:
20 cm is the length of third side of triangle
Step-by-step explanation:
Length of 1st side = a
Length of 2nd side = 10cm = b
Length of 3rd side = 15cm = c
So,
Perimeter of triangle = 45 cm
a+b+c = 45cm
a + 10 + 15 = 45 cm
.'. a = 45-25 cm
= 20 cm
The midline or midsegment has a length equal to half of the third side.
Therefore, the length of the third side is 45 cm × 2 = 90 cm.
Response:
The length of the third side is 90 cmWhich theorem can be used to find the length of the third side?Given:
The length of the midline = 45 cm
Required:
The length of the third side
Solution:
The midline is the line joining the midpoint of two sides of a triangle.
According to the midsegment theorem, the midline of a triangle is
parallel to the third side and has a length equal to half the length of the
third side.
Which gives;
The length of the mid line = [tex]\mathbf{\frac{1}{2}}[/tex] × The length of the third side
Let x represent the length of third side, we have;
45 = [tex]\frac{1}{2}[/tex] × x
Which gives;
The length of the third side, x = 2 × 45 cm = 90 cm

A conglomerate of Christmas tree growers in Oregon wants to know if there is a difference in preference for live Christmas trees between urban and rural regions of the state. They randomly surveyed 160 rural households that put up a Christmas tree the previous season and found that 64 had used a live tree. In a separate random survey, 89 of 261 urban household had put up a live tree the previous season. The 95% confidence interval for the difference of the true proportion of all households (rural - urban) in Oregon that preferred a live tree is between -0.036 and 0.154. Based on the confidence interval, is there convincing evidence that the two population proportions are different
Answers
Answer:
0 is part of the confidence interval, which means that there is not convincing evidence that the two population proportions are different.
Step-by-step explanation:
Based on a confidence interval for the difference of proportions, there will be significant evidence that the proportions are different if 0 is not part of the confidence interval for the difference of proportions.
In this question:
Confidence interval between -0.036 and 0.154
0 is part of the confidence interval, which means that there is not convincing evidence that the two population proportions are different.

65 is what percent of 120?
(round to the nearest percent)
Answers
Answer:Lets say 60 is rounded to 60. So 60 is half of 120 , which means that the answer is a little bit more than 50% since 50x2=100%
So 50 plus the 5 we took away from the 60 in the beginning is 55%
I think your answer is 55%
Step-by-step explanation:
Your answer is 55%
The percentage of 65 out of 120 will be 54.167%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The whole numbers are 65 and 120.
Then the percentage is written as,
P = (65 / 120) x 100
P = 0.54167 x 100
P = 54.167%
The percentage of 65 out of 120 will be 54.167%.
