Answer:
Lowest score needed=4.92
Step-by-step explanation:
Using the standard normal distribution table we find the value of standard normal deviate corresponding to area of 15%
For area of 15% we have Z= -1.04
Thus we have

Applying values we get

Thus lowest score needed = 4.92

9470m above the sea level.
Step-by-step explanation:
<span>2/3 (x-7)= -2

x = -3 + 7
x = 4</span>
Answer: 0=0
Step-by-step explanation:
The answer is 6. You can find slope by using the slope formula: M= y1 - y2 / x1 - x2. In this case you can choose any two points from the table. I chose the second two points. the equation would then be (7-1) / (2-1). It would then be 6/1 or 6.
Hope this helped(:
