Answer:
50km
Step-by-step explanation:
Explanation:
So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by 2.51. Then, 20 x 2.5=50. So the answer is 50 km
Answer:
for line b - the slope is 0, not undefined. an undefined slope is a vertical line.
for line d - the slope is -1/3. slope is written rise over run, so just count the units that it goes down and how many it goes right. it goes down 1 and right 3, so it is -1/3.
Answer:
∠ A ≈ 35.54°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan A = = = , thus
A = ( ) ≈ 35.54° ( to the nearest hundredth )
Answer:
Step-by-step explanation:
Mean = 0.53*23.7% + 0.25*12.7% + 0.22*(-0.112)= 15.71%
standard deviation= sqrt(0.53*(23.7%-15.71%)^2 + 0.25*(12.7%-15.71%)^2 + 0.22*(-0.112-12.40%)^2)= 8.40%
