Answer: POQ = 125

Step-by-step explanation: If you don’t want to read my long explanation, I drew a diagram of my work. :>

First we need to establish that POQ is a vertical angle to SOT, this makes the angles equal. We also need to establish that because the definition of an altitude, that T And S both form right angles. (An altitude is a perpendicular segment from a vertex of a triangle to the opposite side.) Now let’s take a look at the quadrilateral that is formed inside the triangle, the quadrilateral being RSOT. Luckily we know the measure of three of the angles, R=55, T=90, and S=90. If you didn’t know beforehand all angles of a quadrilateral add up to 360, so we can add up the angles we’ve already found to find the missing angle O/ SOT. When we add the angles, and then subtract that from 360 we get 125, so SOT=125. Remember that we established that SOT and POQ are vertical angles, so if SOT=125 then POQ=125.

I really hoped my explanation was good, this was my first time giving an answer. Also I’m sorry if my method of finding the answer wasn’t helpful, but this was the only way I could think of.

I accidentally gave myself a one star rating, that sucks.

Answer:

Yes. Her sample is unrepresentative of the population in her community.

Step-by-step explanation:

a) Data and Calculations:

Population                Study  Census %     Representative       Over/Under

                               Sample                           Sample              Representation

Whites                       300        48%           288 (48% * 600)         12

African Americans      80         12%             72 (12% * 600)           8

Latinos                       100         18%           108 (18% * 600)           (8)

Asians                         40          9%             54 (9% * 600)           (14)

Others                        80         13%             78 (13% * 600)            2

Total                         600      100%          600                                0

b) There is selection bias in her sample. A representative sample of 600 is the subset of a population that seeks to accurately reflect the characteristics of the larger group.   When the sample for each category does not accurately represent the characteristics or attributes of the population categories, then it is unrepresentative.

Sampling is the collection of randomly chosen data from the entire population to come to an end conclusion about the variable to be determined or known.

Yes, the sample is unrepresentative of the entire population.

The reason for the sample being unrepresentative of the entire population in her community is that the selected sample is deviating a lot from the population count.

As per the computation, there is selection bias in her sample. This is because the representative sample is 600 that represents the entire population and reflects the characteristics of the larger group.

The sample becomes unrepresentative when the sample chosen does not accurately represent the true attributes of the population.

Answer:

Ahmed earned £198.00 on that weekend.

Step-by-step explanation:

Given that:

Normal hourly pay = £12.00

Overtime pay = [tex]1\frac{1}{4}[/tex] of normal rate

Overtime pay per hour = [tex]\frac{5}{4}*12[/tex]

Overtime pay per hour = £15.00

Hours worked on Saturday = 9 hours

Amount earned on Saturday = 9*12 = £108.00

Hours worked on Sunday = 6 hours

Amount earned on Sunday = 6*15 = £90.00

Total amount earned on weekend = 108+90 = £198.00

Hence,

Ahmed earned £198.00 on that weekend.

Answer:

Step-by-step explanation:

we know that distance d from the focus to P should be the same to the distance from P to the directrix

(x-h)^2=4p(y-k)

we need to find the y coordinate,

x is the same from focus, 3

y=(3, (4+2)/2)=(3,3)

we find p now by subtracting the y from the focus from the y that we just found

p=4-3=1

again (x-h)^2=4p(y-k), p=1

(x-3)^2=4(1)(y-3)

(x-3)^2=4(y-3),  (x-3)^2=4y-12

simplify

4y=(x-3)^2+12

y=((x-3)^2)/4 + 3

The equation for the parabola would be y = ((x-3)^2)/4 + 3.

We already know that distance d from the focus to P must be the same as the distance from P to the directrix

(x-h)^2 = 4p(y-k)

x is the same from focus 3

y = (3, (4+2)/2)

y  =(3,3)

by subtracting the y from the focus from the y that we get

p = 4-3 =1

similalry,

(x-h)^2=4p(y-k), p=1

(x-3)^2=4(1)(y-3)

(x-3)^2=4(y-3),  

(x-3)^2=4y-12

simplify it;

4y=(x-3)^2+12

y = ((x-3)^2)/4 + 3

Thus, the equation for the parabola would be y = ((x-3)^2)/4 + 3.

Step-by-step explanation:

Answer:

157.5 hours

Step-by-step explanation:

If Craig continued to work 21 hours for 7.5 months he would work a total of 157.5 hours.

Why?

Because if you multiply 21 seven times you get a total of 147 hours, but we still have the .5 of the month so take 21 and divide it by 2 which gives us 10.5 hours.

When you have both you outcomes ready you add 147 and 10.5 hours

Which gives us 147+10.5=157.5 hours.

Good luck :)

Answer:

6 stories

Step-by-step explanation:

1 hour = 60 minutes

We can use a ratio to solve

1/2 story       x story

-------------  = ------------

5 minutes        60 minutes

Using cross products

1/2 * 60 = 5 * x

30 = 5x

Divide each side by 5

30/5 = 5x/5

So first look at the symbol. It must be less than or equal to 17.

By elimination A is 20.5 which is wrong

B is -16.5 by abs =16.5

C is -17.5 by abs = 17.5

D is 12.5

Answer:

The test statistics is  [tex]z = 2.47[/tex]

Step-by-step explanation:

From the question we are told that

    The  sample size is  n =  191 \  buses

     The sample mean is  [tex]\= x = 96 700 \ miles[/tex]

    The population standard deviation is  [tex]\sigma = 37 500 \ miles[/tex]

The null hypothesis is  [tex]H_o : \mu = 90 000[/tex]

The alternative hypothesis is  [tex]H_a : \mu > 90 000[/tex]

Generally the test statistics is mathematically represented as

         [tex]z = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]

=>      [tex]z = \frac{96700 - 90 000 }{ \frac{37500}{\sqrt{191} } }[/tex]

=>      [tex]z = 2.47[/tex]
