Answer: The required expression,

-350+275+70-50

Lee's final score is -55.

Step-by-step explanation:

Given,

The current score of Lee = - 350 points,

Now, he answered 275 point question correctly,

∴ Score he gained = + 275 points,

Again he answered 70 point question correctly,

∴ score he gained = + 70

Finally, he answer 50 point question incorrectly,

∴ Score he gained = - 50 points,

So, the total gaining in score = 275 + 70 - 50

Therefore,

Final score = Current score + Gaining scores = -350+275+70-50 = -55

7. A coin is tossed and a day of the week is selected. What is the probability that you get tails and a day that begins with "S"
Mrrafil [7]

Answer:

1/7

Step-by-step explanation:

Lets start with the probability of flipping tails, 1/2.

Then the probability of the day starting with the letter s, 2/7.

Calculate the final probability by multiplying the two together.

\frac{1}{2}*\frac{2}{7}=\frac{2}{14}

You can simplify 2/14 down to 1/7

Can you help me with my homework please

#4(a)

row-seat: 3- 13, 4-15, 5-17, 6-19, 7-21

(b)

the equation works for row 1 but not for any of the rows after this

Ex: Row 2, S=7(2)+2, this would equal 14 but there isn't 14 seats in row #2

(c)

S=2(1)+7, there is 9 seats in row 1

2(2)+7=11,  there is 11 seats in row 2

2(3)+7= 13, there is 13 seats in row 3

(d)

2(15)+7=37

2*15=30, 30+7=37

(e)

91=2(r)+7

91-7=2(r)+7-7

84=2(r)

84/2=2(r)/2

42=r, the row with 91 seats is row 42
