67.5 mph // 45/2 miles in 1/3 hour times 3 is 135/2 which is 67.5 mph
Hello,
In my old memories,
p(μ-2σ<=X<=μ+2σ)=95%
p(μ-3σ<=X<=μ+3σ)=99%
1000-2*200=1000-400=600
1000+2*200=1000+400=1400
Answer A
Answer:
x ≥ -4
Step-by-step explanation:
filled circle = ≥ ( with equal )
Answer: -14
Step-by-step explanation:
Input the values for the variables into the expression and solve.
4(9) - 2(5)^2 We will evaluate the expoent first.
4(9) - 2(25) Now multiply
36 - 50
36 - 50 = -14
Answer:
Correct options are 2, 5 and 7.
Step-by-step explanation:
Consider the given vertices of triangle are A(-3,-3), B(-3,2) and C(1,2).
Distance formula:
Using distance formula, we get
Similarly,
From the above calculation it is clear that AC>AB and AC>BC.
According to Pythagoras theorem, in a right angle triangle, the square of largest side is equal to the sum of squares of two small sides.
So, given triangle is a right angle triangle and AC is its hypotenuse.
Therefore, the correct options are 2, 5 and 7.
