Answer:
91% of the time the auto will get less than 26 mpg
Step-by-step explanation:
Think of (or draw) the standard normal curve. Mark the mean (22.0). Then one standard deviation above the mean would be 22.0 + 3.0, or 25.0. Two would be 22.0 + 2(3.0), or 28.0. Finallyl, draw a vertical line at 26.0.
Our task is to determine the area under the curve to the left of 26.0.
Using a basic calculator with built-in statistical functions, we find this area as follows:
normcdf(-100, 26.0, 22.0, 3.0) = 0.9088, which is the desired probability: 91% of the time the auto will get less than 26 mpg.
15 tickets = $105
105 ÷ 15 = 7
1 ticket costs $7.
$7 x 12 = $84
12 tickets cost $84
Answer: $84 (Answer C)

Answer: They are proportional.
Explanation: To determine whether a table is proportional just simply notice if there is a number you can get to the next number.
Example: on the x values you multiply from left to right by 2 and get the next number. on the y values you multiply by 1. This table is proportional
Answer:
Option C is correct
Step-by-step explanation:
In similar triangles corresponding sides are in same ratio.
Notice that sides b and q are corresponding ( they are opposite equal angles) and so are a and p
