Answer:
6.2 meters
Step-by-step explanation:
Use pythagorean theorem to find b:
b = √(2.8² - 2.7²) = √0.55 = 0.7 (nearest tenth)
Perimeter of triangle = sum of all its sides = 2.8 + 2.7 + 0.7
Perimeter = 6.2 meters
Answer: x=-5 x=2
Step-by-step explanation:
x^2+5x-2x-10=0 factor out x from the expression
Xx(x+5)-2x-10=0 factor out x+5 from the expression
(x+5)x(x-2)=0 when the product of factors equals 0, at least one factor is 0
x+5=0 solve for the equation x
x-2=0
x=-5
x=2
In a statistics class, 10 scores were randomly selected with the following results: 74, 73, 77, 77, 71, 68, 65, 77, 67, 66. What
julia-pushkina [17]
Answer:
The 65th percentile is between 73 and 74
Step-by-step explanation:
Rearrange the ungrouped data in ascending order: 65,66,67,68,71,73,74,77,77,77
The 65th percentile is 65/100 of N ( N = 10) = 65/100 × 10 = 6.5
The 65th percentile is the 6.5th term. The 6th term is 73 and the 7th term is 74, the 6.5th term is between the 6th and 7th term
The 65th percentile is between 73 and 74
Answer:<u> -0.9 ; inelastic</u>
Explanation:
Given:
The average price of wheat per metric ton in 2012 = $305.75
Demand (in millions of metric tons) in 2012 = 672
The average price of wheat per metric ton in 2013 = $291.56
Demand (in millions of metric tons) in 2013 = 700
We will compute the elasticity using the following formula:
ε = 
ε = 
Now , we'll first compute 
i.e. = 
= 0.04081
Similarly for 
i.e. = 
= -0.0475
ε = 
ε = -0.859 
-0.9
we know that ;
If, ε > 1 ⇒ Elastic
ε < 1 ⇒ Inelastic
ε = 1 ⇒ unit elastic
<u><em> Here , ε = -0.859 -0.9 </em></u>
<u><em>Therefore ε is inelastic.</em></u>
So 8x^2+8x+8-(-9x^2+2x+5) is going to be
8x^2+9x^2+8x-2x+8-5
Giving you
17x^2+6x+3
