C. No, this is not a valid inference because she asked only 35 families
Sarah purchased 2 first class tickets, and 5 coach tickets. This is the answer because $2640- $1020-$1020=$600, and $600÷5=$120.
Answer:
Range: y ≥ 4
Step-by-step explanation:
Range is the y value
y = (x-2)^2 +4
The smallest the squared term can be is zero
y = 0 +4
The smallest y can be is 4
y ≥ 4
Perpendicular angles are where 2 lines form 90 degree angles, such as in C
Answer:
the probability is 0.6
Step-by-step explanation:
The computation is shown below:
Let us assume the X would be the number appear on the top face
Now
= P(X = 1) ÷ P(X = 0)
= 0.3 ÷ 0.3 + 0.1 + 0.1
= 0.3 ÷ 0.5
= 0.6
hence, the probability is 0.6
