1inch= 0,8(3) feet
5,400*0,8333 : 5280= 4,4999 :5280=0, 085 miles
Answer:
See explanation below.
Step-by-step explanation:
The scale factor can be found by dividing two corresponding side lengths. For instance, if you have two triangles, divide the new length of the larger or smaller triangle by the same side length of the original.
If the side length of the new was 9 and the old was 3 then the scale factor would be 9/3 = 3.
If it were flipped then the new would be 3 and the old would be 9. So the scale factor would be 3/9 = 1/3.
Answer:
a
Step-by-step explanation:
sec (thita) = squrt (5)
squaring on both sides:
sec^2 (thita) = 5 - equation 1
1 + tan^2 (thita) = 5
tan^2 (thita) = 4
tan (thita) = 2.
= tan (thita) - squrt(5)sin(thita)
= 2 - squrt(5) x 2/ squrt(5)
= 0
from eqn - 1
sec(thita) = squrt(5)
cos(thita) = 1/ squrt(5)
sin(thita) = squrt ( 1- 1/(squrt (5))^2)
sin(thita) = 2/ squrt(5) .
Answer:
Option b, c and e are wonderful approaches to solve the problem.
Step-by-step explanation:
Option (b) is appropriate this is because the option is talking about Simple random sampling where random universities are chosen to remove bias.
Option (c) is correct because this is an example of Stratified sampling where two homogenous groups (private and public universities are considered) and samples are chosen at random to remove bias
Option (e) is correct because this again is an example of Simple random sampling where 60 random STEM majors are chosen at random.
Answer:
See below:
Step-by-step explanation:
Take the difference between y values of any two values and divide by difference in corresponding x values
for example, 1: 66-50/4-1=16
2. 36-30/8-6= 6/2=3
3. 63-56/8-7= 7/1 = 7
4. 100-78/9-7= 22/2 = 11
you can choose any two points, not just the two I used.
