Answer:
45.94%
Step-by-step explanation:
Probability-Above 45.94%
Z =0.1
x= 61
µ 60
σ 9.8
Here we MUST do the exponentiation first, followed by the mult. The add'n. is done last.
81 + 4(9) = 81 + 36 = 117 (answer)
Answer:
49.47 m
Step-by-step explanation:
You will need to use the cosine function
which is the ratio adjacent side/hypotenuse
So, let x = length of guy wire
then cos 14 = 48/x
x cos 14 = 48
x = 48/cos 14
= 49.47 m
Note: You must memorize the definitions of all the trig functions so you can do problems like this one. OK?
Answer:
105:175
Step-by-step explanation:
3+5 = 8
3/8 of 280 is 105.
5/8 of 280 is 175.
the ratio is 105:175
next we have to simplify it:
divide both sides by 5:
21:35 divide both sides by 7=
3:5
