<span>The area of a triangle is 6.75 m^2
=> (1/2) x base x height=</span>6.75 m^2
=>(1/2) x 3 x <span>height = </span>6.75
=><span>height = (</span>6.75x2)/3= 4.1
so the height is 4.1m
Answer:
on ed its the first one and the second one
Complete Question
A civil engineer is analyzing the compressive strength of concrete. Compressive strength is normally distributed with. A random sample of 12 sample specimens has a mean compressive strength of . Round your answers to 1 decimal place. (a) Calculate the 95% two-sided confidence interval on the true mean compressive strength of concrete.
Answer:
Step-by-step explanation:
From the question we are told that:
Sample size
Standard deviation
Sample mean
Confidence level =95%
significance level
From table \alpha 0.05
Gives
Generally the equation for confidence interval is mathematically given by
Answer:
1. 20² = 400
2. 4⁴ = 256
3. 2⁷ = 128
4. 3⁵ = 243
5. 10³ = 1,000
6. 7⁶ = 117,649
7. 25³ = 15,625
8. 5⁷ = 78,125
9. 6.5² = 42.25
i wasnt really sure what you meant but i hope this helps
Area = length × width
Length = 1/2 yd
Area = 3/8 yd
All you have to do is divide area by length to get width
3/8 ÷ 1/2
Keep 3/8
Change ÷ to ×
Flip 1/2 to 2/1
That equals 3/8 × 2/1 = 6/8 = 3/4
Width = 3/4 yd
