Answer:
24
Step-by-step explanation:
in one hour he can serve 12, hence 12x2=24
The correct answer to this question is 4.
In order to solve this problem, first make an image on your mind how the image is dilated.
The coordinate points at first is (1.5, 2.0). After dilation from the origin, the points became (6.0, 8.0)
Looking at it in fraction form, (new / old) we have
6.0 / 1.5 = 4.0
8.0 / 2.0 = 4.0
The quotient of each fraction yields to 4.0. This means that a = 4.
Answer:
a. 81.5%
Step-by-step explanation:
The z-score for 400 is ...
Z = (X -μ)/σ = (400 -500)/100 = -1
The z-score for 700 is ...
Z = (700 -500)/100 = 2
The empirical rule tells you that 68% of the distribution is within ±1σ of the mean, and 95% is within ±2σ of the mean. Half of that first number is in the range Z = -1 to 0, and half that second number is in the range Z = 0 to +2. So, the probability you want is ...
(1/2)(68%) + (1/2)(95%) = 81.5% . . . . matches choice A
