Answer:
The scale factor of all radii of circle Y to all radii of circle Z is 2.5
Step-by-step explanation:
we know that
The radius of circle Y is 4 units
The radius of circle Z is 10 units
To find the scale factor of all radii of circle Y to all radii of circle Z, divide the radius of circle Z by the radius of circle Y
10/4=2.5
98 divided by 7 is 14. 14 multiplied by 3 is 42. So there are 42 girls.
Answer:
The experiment design used in this case is the between-subjected design.
Step-by-step explanation:
Between-subject design is a sort of experimental design where the individuals of an experiment are allocated to varied situations, with each individual being treated with only one of the experimental conditions.
In this case three similar ecosystems are designed containing a variety of insects and plants. Then each ecosystem to be exposed to rock music, country music, or a conventional city soundscape for two consecutive weeks.
Then after two weeks period they measured how successful the species were in each ecosystem.
The experiment design used in this case is the between-subjected design.
Answer:
3/2 is slope
m= slope
y=mx+b
Step-by-step explanation:
2y=3/2x+7/2
Answer:
14/15
Step-by-step explanation:
This is because 8/15 and since you need to find the least common factor which is 15, multiply 3 times 5 and 3 times 2 which is 6/15 and 8/15+6/15=14/15
