A ladder placed 7 feet away from a wall,and makes 45 angle with ground.what is the length of the ladder?
elixir [45]

Answer:

L = 14/\sqrt2} <u>OR</u> 9.899

Step-by-step explanation:

cos(angle) = adjacent/ hypotenuse

hypotenuse = length of ladder

adjacent = 7 feet

length of ladder = L

1/L = cos(45)/7

L = 7/cos(45)

<u><em>MAKE SURE CALCULATOR IS IN DEGREE MODE</em></u>

L = 7/(\sqrt{2}/2)

L = 14/\sqrt{2}

In a study of facial behavior, people in a control group are timed for eye contact in a 5- minute period. Their times are normal
Lorico [155]

Answer:

0.20148

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 230

μ is the population mean = 184

σ is the population standard deviation = 55

z = 230 - 184/55

z = 0.83636

P-value from Z-Table:

P(x<230) = 0.79852

P(x>230) = 1 - P(x<230) = 0.20148

Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148
