Answer:

<em>A = {MOPN. MPON, PMON, POMN)</em>

Step-by-step explanation:

<u>Complete Question</u>

<em>Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last  skater. Then, they try to decide whether or not Oliver should be the first skater in the race. </em>

<em>Which subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race? </em>

<em>A = {MOPN, PMON} </em>

<em>A = {OPMN, OMPN) </em>

<em>A = {MOPN,MPON, OPMN, POMN) </em>

<em>A = {MOPN. MPON, PMON, POMN)</em>

<em />

So,

Naim would be last, that means, "N" must come last in all the sets. All of them have this, so that's good.

Now, they want "COMPLEMENT" of the set where Oliver is 1st. Complement is the "opposite" event, not in set/subset. So we disregard anyone where there is "O" in first place.

1st set have only 2 possibilities, so that's out.

2nd set have same, so that's out.

3rd set has "O" at first place in third sub, so that's out.

4th set DOESN'T have "O" in first place and has 4 subs, so this is the correct answer.

<em>A = {MOPN. MPON, PMON, POMN)  -- correct</em>

4. A cruise ship travels in the direction of 55degrees for 40 miles, then changes course to a direction of 100 degrees for 35 mi
olga2289 [7]

Answer:

69.3 mi

Step-by-step explanation:

Let x represent the distance of the ship from its original position.

x²= 40² + 35² -2(40)(35)cos(135)

x^{2} =4804.9

\sqrt{x} ^{2}  = \sqrt{4804.9}

x= 69.3 mi

Which pairs of angles in the figure below are vertical angles?
ch4aika [34]

Answer: Option A and Option C.

Step-by-step explanation:

For this exercise it is important to know the definition of "Vertical Angles".

When two lines intersect or cross, there are a pair of angles that share the same vertex and they are opposite each other. This pair of angles are known as "Vertical angles".

By definition, Vertical angles are congruent, which means that the have the equal measure.

In this case, you can observe in the picture provided in the exercise that the line TI and the line WN intersect each other at the point S.

You can identify that the pair of angles that are opposite to each other and share the same vertex are the shown below:

\angle ISN  and \angle TSW

\angle TSN and \angle ISW

mart [117]

Answer:

g(x) = \sqrt[3]{x-1} - 2

Step-by-step explanation:

We want to find h and k in:

g(x) = \sqrt[3]{x-h} + k

At the inflection point, the second derivative is equal to zero, so:

g'(x) = \frac{1}{3} (x-h)^{\frac{-2}{3}}

g''(x) = \frac{1}{3} \frac{-2}{3}(x-h)^{\frac{-5}{3}} = 0

Then x - h = 0.

Inflection point is located at (1, -2), replacing this x value we get:

1 - h = 0

h = 1

We know that the point (-2.5, -3.5) belongs to the function, so:

-3.5 = \sqrt[3]{-2.5-1} + k

k ≈ -2

All data, used or not, are shown in the picture attached.

arleen has a gift card for a local lawn and garden store. she uses the gift card to rent a roller for 4 days. it cost $17 per da
kaheart [24]

Answer:

We use negative values for the money Arleen spends.

a) We determine the change to the value on her gift card:

4(-35)+(-9)= -140+(-9)=-149

b) We determine the amount on money she has left on the gift card after renting the tiller and buying the rake:

200+(-149)=51

Since she has got $51 on her gift card and a wheelbarrow is $50 she is able to buy it:

51>50

RESULT

a) -$149 less b) yes
