Answer:
Concept: Higher Level Mathematics
- You have a density curve, aka probability
- You are asked to find the height
- Hence 0-40F has 40 total integers or values of X(probability)
- Hence you have a total Area of
- Integrate f(x) to get 0.025.
- Hence the answer is A
- Rate positively and give brainlist
Answer:
a = 9 / 7
step by step explanation:
9 / - a + 15 = 8
Determined the defined range
9 / ( - a ) + 15 = 8 , a ≠ 0
subtract 15 from each side
9 / - a + 15 - 15 = 8 - 15
calculate the difference
9 / - a = - 7
multiply both side of equation by - a
9 / - a × - a = - 7 × - a
9 = 7 a
divide each side by of equation by -7
9 / 7 = 7 a / 7
9 / 7 = a
swap the side of equation . ( optional )
a = 9 / 7
Answer:
v = 130
Step-by-step explanation:
substitute the given values for u, a and t into the equation
v = 32 + ( 9.8 × 10) = 32 + 98 = 130
I think the answer is B.
