Answer:
The answer is 3, it's the only answer closest to 200
Step-by-step explanation:
For given problem:
Put midpoint of ellipse, (0,0) at epicenter of bridge at
ground level.
Specified length of vertical major axis = 70=2a
a=35
a^2=1225
Equation of ellipse:
x^2/b^2+y^2=1
plug in coordinates of given point on ellipse(25, 10)
25^2/b^2 + 10^2/a^2 = 1
625/b^2 + 100/1225=1
625/b^2 = 1 - 100/ 1225 = .918
b^2 = 625/.918 ≈ 681
b ≈ 26.09
length of minor axis = 2b = 2(26.09) ≈ 52.16 ft
Span of bridge ≈ 52.16 ft

Answer:
5,5,7,8,10
Step-by-step explanation:
mode=5 so that would appear the most so start with 5,5
median=7 that would be the middle number so 7 would be next
when you add 5+5+7=17 now just choose any number to add to 17 and I choose 10 which makes 17+10=27.
mean=7 so that means the total has to be divided by how many numbers you have, which is 5. So the total divided by 5 should equal 7. Since have 27, the number divided by 5 to get 7 is 35. So, add to 27 to get 35 which would be 8.
27+8=35 that is your total. Now divide by 5 to get the mean of 7.
Solution:
<u>Note that:</u>
- Area of triangle = 6 3/8 yd²
- Height of triangle = 2 1/2
- Area of triangle = 1/2 x base x altitude
<u>Use the formula to find the base of the triangle.</u>
- 1/2 x base x altitude = 6 3/8 yd²
- => 1/2 x base x 2 1/2 = 6 3/8 yd²
- => 1/2 x base x 5/2 = 6 3/8 yd²
- => 5/4 x base = 6 3/8 yd²
- => base = 6 3/8 ÷ 5/4 yd
- => base = 51/8 x 4/5 yd
- => base = 51/2 x 1/5 yd
- => base = 51/10 yd
The length of the base is 51/10 yards.
