Answer:
50 beats/min
Step-by-step explanation:
normal heart rate = h
20% of h = 10
20/100 * h = 10
h = 10*5
= 50 beats/min
Hope this help!
Answer:
32
Step-by-step explanation:
So the order of the points is: GHJK
GH = x+10 =JK
HJ=8
JK=2x-4
JK = x+10=2x-4
x+10=2x-4
10+4=2x-x
x=14
GH= 14+10 =24
GJ = GH +HJ = 24+ 8=32
Right away, mode is not applicable because mode entails the repetition of the same number. No numbers are repeated here.
To find median, you must put the numbers in numerical order. You should get
111, 114, 121, 179, 216, 220, 234, 246
Next, find the middle. In this case, the middle is split between 179 and 216. To find the median, add 179 and 216 then divide by two. You should get 197.5.
To find the mean, add all the numbers then divide by the number of numbers present (in this case there are 8 numbers). You should get 180.125.
Because the median and mean are off, it is safe to say A is the correct choice.
Answer:
C. x = 11, m∠Q = 55º
Step-by-step explanation:
125 + 5x = 180
5x = 55
x = 11
5x = 55
C. x = 11, m∠Q = 55º
Answer:
x ≈ 6.2 cm
Step-by-step explanation:
using the cosine ratio in the right triangle
cosΘ = 
, that is
cos39° = 
= 
( multiply both sides by 8 )
8 × cos39° = x , then
x ≈ 6.2 cm ( to 1 dec. place )
