In ΔBCD, the measure of ∠D=90°, BD = 13, DC = 84, and CB = 85. What is the value of the cosine of ∠C to the nearest hundredth?

Morgarella [4.7K]

Answer: 0.99

Step-by-step explanation: sin 90 Divided by 85 = sin x divided by 13

sin x =13x sin 90 divided by 85

sin x = 13divided by 85

sin x = .152941176

arc sine of .152941176= 8.79741071 degrees

cos 8.79741071 = .988235294

A sensitive measuring device is calibrated so that errors in the measurements it provides are normally distributed with mean 0 a

Artemon [7]

Answer: 0.9660

Step-by-step explanation:

Given: Mean : $\mu =0$

Variance : $\sigma^2=2.00$

⇒ Standard deviation : $\sigma = \sqrt{2}$

The formula to calculate z is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x= -3

$z=\dfrac{-3-0}{\sqrt{2}}=-2.12132034356\approx-2.12$

The P Value = $P(z$

For x= 3

The P Value = $P(z$

$\text{Now, }P(-3$

Hence, the probability that a given error will be between -3 and 3=0.9660
