Given,  

∠AOE = 30°

∠DOB = 40°

So, ∠EOD = 180 - (30+40)           [angles on a straight line]

                =  180 - 70

                =  110

∠EOD = ∠COF                             [ vertically opposite angle]

∴ ∠COF = 110°

91°-32°=
59°
The line EF total angles must equal 180°. Therefore angle EOB is 89°, (180-91). Then line AB must also equal 180°. And angle EOB is 89° and angle COA is 32°. Take 89+32 which is 121. 180-121=59. Finally, that leaves angle COE with an angle measure of 59°.

The school that Lisa goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 4 se
kakasveta [241]
Let:
x = cost of senior citizen ticket
y = cost of student ticket

4x + 5y = 102
7x + 5y = 126

4x + 5y = 102
4x = 102 - 5y
x = (102 - 5y)/4
x = 102/4 - 5y/4

7x + 5y = 126
7(102/4 - 5y/4) + 5y = 126
(714/4 - 35y/4) + 5y = 126
-35y/4 + 5y = 126 - 714/4

note:
-35y/4 = -8.75y
714/4 = 178.5

-8.75y + 5y = 126 - 178.5
-3.75y = -52.5
y = -52.5/-3.75
y = 14


x = 102/4 - 5y/4
x = 102/4 - 5(14)/4
x = 8

x = cost of senior citizen ticket = $8/ea
y = cost of student ticket = $14/ea

Suppose the population of IQ scores in the town or city where you live is bell-shaped, with a mean of 104 and a standard deviati
SVEN [57.7K]

Answer:

The mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.  

Step-by-step explanation:

We know the population mean and standard deviation, that has a bell-shaped distribution:

\mu=104\\\\\sigma=35

The sampling distribution, the distribution of the mean of samples of size n out of this population, will have the same mean as the population mean.

\mu_M=\mu=104

The standard deviation will be related to the population standard deviation and the sample size as:

\sigma_M=\frac{\sigma}{\sqrt{N}} =\frac{35}{\sqrt{100}}=3.5

Then, the mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.
