Answer:
Option I
Step-by-step explanation:
Given that for families who live in apartments the scatterplot of the family’s income and the amount of rent they pay is approximately linear with a correlation of r = 0.60.
This implies that there is a positive association between income and rent paid.
Also since r is greater than 0.5, we can say that there is a moderately strong correlation.
All these can be interpreted as if income goes high, rent also would be higher.
The rise in rent due to income would be 0.6^2 =36% only
The regression line need not pass through 60% of income rent data points but it passes through average of the data points.
Hence only option I is right.
12 boys 3 boys
------------- reduces to ------------
16 girls 4 girls
We want the simplified ratio of girls to students. There are 12+16, or 28, students to start with. We must reduce 16/28, which is the ratio of girls to students before simplification. This reduces to 4/7 (4 to 7).
The answers are
a) the domain is all real numbers
d) the input to an exponential function is the exponent
e) the base represents the multiplicative rate of change
hope this helps :)
Answer:
18000 milimeters
Step-by-step explanation:
the conversion rate for meters to 1 to 1000
so you do 18*1000= 18000 milimeters
