Volume of a triangle: 1/2(2b × h)
The 1/2 and 2 cancel each other out, so it's just b × h.
Area of base: 8 × 8 = 64 cm²
Height: 12 cm
64 × 12 = 768
The volume of the triangle is 768 cm³.
Answer: 95% confidence interval would be (0.013,0.167).
Step-by-step explanation:
Since we have given that
survey of teachers found that 224 of 395 elementary school teachers,
So, n₁ = 395
x₁ = 224
So,
n₂ = 266
x₂ = 126
So,
At 95% confidence level, z = 1.96
So, interval would be
Hence, 95% confidence interval would be (0.013,0.167).
50 degrees
Step-by-step explanation:
the x is 0 so 0 -50 is 50 so your answer is 50 degrees
