sumfor(k, 1, 35, (sin(5*k)) =tan(r)

r = 87 1/2 Degrees.

A line whose y intercept is (0, 5) intersects the ellipse 9x²+16y² = 144 . Find all possible slopes of this line, express your answer in interval notation.

(a) The probobality would be 1/3^6 so 1/216

(b) we are drawing 1,2,4,5,6 so 5/6

(c) I'm not sure what you mean here. Do you mean it is odd. It has to be greater than two, and 5 is included. If so then 3,5 are your only options. The probabality of that are 2/6 = 1/3.

You have one square that is 11 m on a side.  Its area is 11² 

You have four quarter circles which is equivalent to one whole circle with radius 5.5 m.  Its area is 3.14 x 5.5²  

Figure up those two areas and subtract the circle from the square. 

121 square meters – 94.985 square meters  =  26.015 square meters, rounded is 26.02 square meters

My teacher is lost and confused as well...... HELP!

OH YEAH ACTUALLY 

o oops, didn't see that you wrote "Three of the following four answers are correct; one is incorrect; you'll have to figure out which one is incorrect and correct it"

for d), shouldn't it be 20%*20%*80%?

I did.

OK THANK U SO MUCH

Did you look it up in your Textbook? It should all be explained there. If you don't understand it, then consult your Math Teacher. Good luck to you.

THANK YOU SO MUCH!!

a) 80% * 20%  * 80% = 16/125 = 12.8%
 

b) 80%^3 = 51.2%

c)20%^3 = 0.8%
 

d)20%*20%*80% = 3.2%

not sure about these

Probability of making a shot:  0.80

Probability of missing a shot:  0.20

Three of the following four answers are correct; one is incorrect; you'll have to figure out which one is incorrect and correct it ===

a)  0.80 x 0.20 x 0.80

b)  0.80 x 0.80 x 0.80

c)  0.20 x 0.20 x 0.20

d)  0.80 x 0.80 x 0.20

The bottom rectangular box has a

floor:                                  10 in x 12 in  =

left-side:                             10 in x 12 in  =

right-side:                           10 in x 12 in  =

front:                                   10 in x 10 in  =

back:                                   10 in x 10 in  =

The top triangular region has a
left-triangular-section:    ½ x 12 in x 5 in  =

right-triangular-section:  ½ x 12 in x 5 in  =

back:                                     5 in x 10 in  =

slant-side:                           13 in x 10 in  =

Calculate these area and sum them ...

47% of the voters were Democrats; she received 82% of this vote:      0,47 x 0.82  =  38.54%

36% of the voters were Republicans; she received 22% of this vote:    0.36 x 0.22  =     7.92%

17% of the voters were Independents; she recieved 26% of this vote:  0.17 x 0.26  =     4.42%

Adding these together, we see that she received 50.88% of the vote.

The Republican share was 7.92 / 50.88  =  15.57%.

Therefore, the probability that a vote for the incumbent is  0.1557.

Do it brute force, entering all positive integers n in order until reaching 13 (n=3, remainder 2, n=4, remainder 0, etc.). All numbers 'n' greater than or equal to 13 will have a remainder of 16, so when discarding the two remainders that repeat (2 and 0) the answer is 9.

Let x = students and y = nonstudents. The total number of admitted fans = x + y = 259. The total in money spent would therefore be 3x + 5y = 831.
Your equations:
x + y = 259
3x + 5y = 831

Solve for y by multiplying the 1st equation by 3 and subtracting:
   3x + 5y = 831
- (3x + 3y = 777)
----------------------
  0x + 2y = 54    =>  y = 27
Since x + y = 259 and y = 27, x = 259 - 27 = 232.
232 students and 27 nonstudents bought tickets.

hope ginger sees this bro 😞
