Answer:
2 3/4 or 2.75
Step-by-step explanation:
Cross multiply
1 ×
16 44
44 × 1 = 44
44÷ 16 = 2 12/16
Simplify 12/16
12÷4= 3
16÷4= 4
2 3/4
Answer:
There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
Step-by-step explanation
The quantity you want is the area under the standard normal curve (with mean 100 and std dev 15) between 110 and 120.
According to my TI-83 calculator,
normalcdf(110,120, 100, 15) = 0.16, or 16%.
-2 would at the end equal zero
2 at the end would equal -480
so i would go with the x=-2
In the second parenthesis is the -2 and -5 inside the house or is -5 separate
