Answer: C

Exp:

∠DXC = 90°
∠CXB = 90°
supplementary = 180°
90+90= 180

If cos theta is -5/13 and sin θ < 0, what is tan θ ?

tensa zangetsu [6.8K]

Take the right angled triangle with sides 13, 12 and 5. sine theta will be 12/13

When sin theta < 0 and cos theta < 0 we are in the third quadrant so sin theta will be -12/13

tan theta = sin theta / cos theta = -5/13 / -12/13 = -5*13 / -12*13 = 5/12

Find the diameter of the sphere with the volume of 36 pi cubic units

kobusy [5.1K]

Answer:

${ \tt{volume = \frac{4}{3} \pi {r}^{3} }} \\ 36\pi = \frac{4}{3} \pi \times {(2d)}^{3} \\ \frac{36 \times 3}{4} = 8 {d}^{3} \\ 27 = 8 {d}^{3} \\ {d}^{3} = \frac{27}{8} \\ diameter = 1.5 \: units$

The time it takes a printer to print a job is an Exponential random variable with the expectation of 12 seconds. You send a job

Mnenie [13.5K]

Answer:

0.8753

Step-by-step explanation:

Calculate the probability that your job will be ready before 10.01 am

Here, the parameter of an Exponential is E(X)=12

Now, to calculate the third job probability, it follows Poisson Distribution with parameter 1/λ

Therefore, E(Y) =1/12

Here, The third job will be ready for 10:01 AM, then E(Y)=61/12

Therefore, the required probability is

$P(X\geq 3)=1-P(X$

=1- POISSON(3,5,true)

=1-0.1246

=0.8753
