There are special trigonometric angle ratios for right triangles, which are sine (sin), cosine (cos), and tangent (tan). Sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, and tangent is opposite over adjacent. 
You can remember this with SOHCAHTOA. S=sin, O=opposite, H=hypotenuse

The angle is given along with its adjacent side (1.2) and the hypotenuse (x). Use cosine. 
Cos(33) = adjacent/hypotenuse
Cos(33) = 1.2/x
x = 1.2 / cos(33)

Now type into your calculator 1.2 / cos33

Tourists from a tour bus were asked about places they visited during their stay in a city. The results are shown in the table.
nlexa [21]
<span>Given:

                             visited museum           didn't visit museum      Total

visited zoo                      9                                     14                           23

didn't visit zoo               5                                        2                              7

Total                             14                                     16                           30

Simply look at the table and check the number that corresponds to visitors who visited the museum but did not visit the zoo. The number is 5. 
Divide it by the total number of people surveyed. Total is 30.

Probability visited the museum but did not visit the zoo = 5/30 = 0.16666 or 16.67%</span>

A construction zone on Interstate 15 has a speed limit of 40 mph. The speeds of vehicles passing through this construction zone
monitta

Answer:

a. The percentage of vehicles who pass through this construction zone who are exceeding the posted speed limit =90.82%

b. Percentage of vehicles travel through this construction zone with speeds between 50 mph and 55 mph= 2.28%

Step-by-step explanation:

We have to find

a) P(X>40)= 1- P(x=40)

Using the z statistic

Here

x= 40 mph

u= 44mph

σ= 3 mph

z=(40-44)/3=-1.33

From the  z-table   -1.67 = 0.9082

a) P(X>40)=

Probability exceeding the speed limit = 0.9082 = 90.82%

b) P(50<X<55)

Now

z1 = (50-44)/3 = 2

z2 = (55-44)/3= 3.67

Area for z>3.59 is almost equal to 1

From the z- table we get

P(55 < X < 60) = P((50-44)/3 < z < (55-44)/3)

     = P(2 < z < 3.67)

     = P(z<3.67) - P(z<2)

     = 1 - 0.9772

     = 0.0228

or 2.28%
