1. 1/3 for 14 3/4+ 1/6= 15 6/12 now 17 -15 6/12 =1 6/12 which is the same as 1 1/3
17 pieces of ribbon can be created if i calculated correctly.
Answer:
Step-by-step explanation:
To answer this we need only know that negative parabolas are upside down, so by definition, it has a max point at the vertex. To find the vertex (h, k), the easy way to do this is to fill in the following expressions for h and k and solve:
and (These are derived from the quadratic formula). Filling in knowing our a = -1, b = -7, c = 12:
and
so the vertex (aka max height occurs at . Depending upon what is meant by stating the max value, we may only need to state the k value (which is the same as the y coordinate, which is an up or down thing as opposed to the x value which is a side to side thing). The domain is all real numbers, as is the case for all x-squared parabolas, and the range is
R = {y | y ≤ 97/4}
I can't see your choices so match them up from these answers to the ones in the list of choices.
Answer:
Option B) 3.04
Step-by-step explanation:
We are given the following in the question:
Number of people interviewed,n = 163
Number of people hire, x = 121
Proportion of people hire =
Mean, μ = 3.3
Standard Deviation, σ = 0.4
We are given that the distribution of GPA for the successful interviewees is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.742
Calculation the value from standard normal z table, we have,
Thus, cut-off GPA should be 3.04.
Option B) 3.04
