Answer:
Option B. 8
Step-by-step explanation:
Hence, required value of d is 8.
Answer:
AB = 4.41
Step-by-step explanation:
cos theta = opposite / hypotenuse
We know theta = 25 and the opposite side =4
cos 25 = 4 / hypotenuse
Multiply each side by hypotenuse
hypotenuse * cos 25 = 4/ hypotenuse * hypotenuse
hypotenuse * cos 25 = 4
Divide each side by cos 25
hypotenuse * cos 25/ cos 25 = 4/cos 25
hypotenuse = 4/cos 25
hypotenuse = 4.413511676
Round to the nearest hundredth
hypotenuse = 4.41
Answer:
Step-by-step explanation:
Now the key here is manipulating the scale:
For 3 every 2cm = 15mi
Divide by 2 so every 1cm = 7.5mi
So if we had 16.27cm then that would equal 16.27 x 7.5 = 122.025mi on the actual scale
Same for 4: if 1/2cm = 20mi
Then multiply times 2 and every 1cm = 40mi
So 11.73cm x 40 = 469.2mi on the actual scale
Hopefully this is right and it helps!
3x+11=65
3x=54
x=18
180-(35+65)=y
180-100=y
80=y
Answer:
5.5
Step-by-step explanation:
2,3,3,4,5,7,8,8,8,10,10,12
The mean of this data is 7.5. So what you are trying to figure out is the mean between 2 and 7. Since that is 3 and 4 it would be 3.5. So 3.5 is the Q1. Now you have to figure out the mean between 8 and 12. That is 9. This is Q3. You have to subtract 9-3.5 and that is the interquartile range. So 5.5 is the answer. I hope that made sense.
