Answer:
f(x)=4x+7
Step-by-step explanation:
f(x)=4x+7
so that is the answer to the questions
Answer:
See below in bold.
Step-by-step explanation:
Mean = 150 cm = 150 * 0.033 feet
= 4.95 feet.
The standard deviation = 10 cm = 10 * 0.033
= 0.33 feet.
Answer:
Not proportional.
A winter, B is spring, C is summer and D is fall.
Step-by-step explanation:
A proportional relationship has a constant of proportional which can be formed by a ratio between any y and x values of the function. The constant will be the same every time.
The ratio y/x is 25/1, 40/2, 55/3, 70/4, and 85/5. These simplify to 25, 20, 13.33, etc. These are not the same values. This is not proportional.
In the attached graph the lows or "valleys" are the coldest parts of the year. A and D are likely Fall and Winter. While B grows and temperatures get higher then B is likely Spring. This means C is summer since it has the highest temperatures.
