If its 20 more than last month that means x + $20 = $70, solve that and you get x = $50, last month she saved $50
7/10 because there is two places after the decimal point making it 100 so move the decimal point two places to the right which makes it 70 and 70/100 in simplest form is 7/10 <span />
I believe by intersect, you mean perpendicular. Also, skew lines can be on parallel planes and still intersect. If they intersected, then the degrees must be 90
Step-by-step explanation:
Use the following information to answer the next 14 exercises: The mean age for all Foothill College students for a recent Fall term was 33.2. The population standard deviation has been pretty consistent at 15. Suppose that twenty-five Winter students were randomly selected. The mean age for the sample was 30.4. We are interested in the true mean age for Winter Foothill College students. Let X = the age of a Winter Foothill College student. n=
