A=1, c=25/7(3.571429) b=?
c=hypotenuse
a=side
In this case, we are finding for a SIDE and not the HYPOTENUSE.
Using Pythagoras' theorem
side²= hyp²–side²
b²= 3.57²–1²
b²= 12.7–1
b²= 11.7
b²= √11.7
b²= 3.4(correct to 1 dp)
Therefore, b= 3.4
HOPE THIS HELPS.... IF NOT I'M SO SORRY :'(
IF IT HELPS YOU PLEASE THANK ME AND GIVE ME BRAINLIEST :)
Answer:
5 ; 0.728 ; 0.00002
Step-by-step explanation:
According to the Central limit theorem, for a normal distribution, the population mean equals the sample mean., Hence the population mean, μ = sample mean = 5
The standard deviation of sampling distribution :
Standard deviation / sqrt(n)
σ / sqrt(n)
σ = 3 ; n = 17
3 / sqrt(17)
3 / 4.1231056
= 0.7276
= 0.728
3.)
P(x < 2) :
Using :
Z = (x - mean) ÷ s/sqrt(n)
P(x < 2) = (2 - 5) ÷ 3/sqrt(17)
P(x < 2) = -3 / 0.7276068
P(x < 2) = - 4.1231060
Z < - 4.123 = 0.00002 (Z probability calculator).
The answer is 5.39 rounded to the nearest hundredth.
