Answer:

0.227

Step-by-step explanation:

Given that X is binomial with n=7 and p =0.5

To find the probability for P(X<3)

i.e. we have to find prob as =P(x=0,1,2)

=P(X=0)+P(X=1)+P(x=2)

P(X=r)=7Cr(0.5)^7

Using binomial table we find prob

P(X<3)=0.2265

Round off this to 3 decimals as

0.227

Hence answer is 0.227

In this figure, sin(a) = 23
WITCHER [35]
a and b are complementary, or b=\dfrac\pi2-a. So

\cos b=\cos\left(\dfrac\pi2-a\right)=\sin a

and so \cos b=\dfrac23.

In right ∆LMN, sin M = 0.759. What is cos N? A. 0.121 B. 0.241 C. 0.349 D. 0.651 E. 0.759
Hatshy [7]

Answer:

E. 0.759

Step-by-step explanation:

You can take this right triangle to have a base length side LM , height of LN and a hypotenuse of MN

The sine of angle ∠LMN is 0.759, find the value of ∠LMN

sin^-1(0.759)=49.38

∠LMN=49.38°

Find angle ∠LNM

You know sum of angles in a triangle add up to 180°, given that this is a right-triangle, the base angle is 90° hence

∠LNM=180°-(90°+49.38°)

∠LNM= 180°-139.38°=40.62°

Find cos 40.62°

Cos 40.62°=0.7590

mary went to her local Zoo where 55% of it's exhibit feature reptiles if the zoo features 20 exhibits in total how many of the z
IceJOKER [234]
Hello!

To find this you have to find what 55% of 20 is

You can do this by doing 20 * 0.55

0.55 is 55% as a decimal

This gives us the answer of 11

Hope this helps!
