Answer:

using pythagoras theorem

H^2=P^2+B^2

here h=MN ,opposite(P) be 15 and adjacent(B) be 16

(MN)2=15^2+16^2

(MN)^2=225+256

MN= $\sqrt{481}$

MN=21.93

after rounding off MN=21.9

A study of womenâ€™s weights found that a randomly selected sample of 234 women had a mean weight of 157.3 lb. Assuming that the

evablogger [386]

Answer:

(155.301 ; 159.299)

Step-by-step explanation:

Xbar = 157.3

Sample size, n = 234

Population standard deviation, σ = 15.6

The confidence interval :

Xbar ± standard Error

Standard Error = Zcritical * σ/√n

Zcritical at 95% = 1.96

Standard Error = 1.96 * (15.6/√234) = 1.999

Lower boundary : 157.3 - 1.999 = 155.301

Upper boundary : 157.3 + 1.999 = 159.299

(155.301 ; 159.299)

Find sec(x) and csc(x) if tan(x) = 3 and cos > 0

Zielflug [23.3K]

Recall that

$1+\tan^2x=\sec^2x\implies\sec x=\sqrt{1+\tan^2x}$

We know to take the positive root here because $\cos x>0$ , which means $\sec x>0$ as well. Then

$\sec x=\sqrt{1+3^2}=\sqrt4=2\implies\cos x=\dfrac12$

We then have

$\tan x=\dfrac{\sin x}{\cos x}=\dfrac{\sin x}{\frac12}=3\implies\sin x=\dfrac32\implies\sec x=\dfrac23$
