Answer:

m∠S = 54.1°

Step-by-step explanation:

Use the law of cosines

s^{2}  = t^{2} + u^{2}  - 2utcos S\\6.1^{2} = 3.2^{2}  + 7.4^{2}  - 2(3.2)(7.4) cos S

37.21 = 10.24 + 54.76 - 47.36 cos S

-27.79 = -47.36 cos S

.586782 = cos S

arccos .586782 = S

m∠S = 54.1°

A die is loaded so that the number 6 comes up three times as often as any other number. what is the probability of rolling a 1 o
Mila [183]

Answer:

1/2.

Step-by-step explanation:

Probability totals must add up to 1.

P = probability.

If P(any number other than 6) = x,  then P(6) = 3x, so

3x + 5x = 1

x = 1/8

P(6) = 3/8 and P(not 6) = 1/8

Therefore P(6 or 1) = 3/8 + 1/8 = 1/2 (answer).

Solve for q.<br> mn + q = p<br><br> q = p - mn<br> q = p (mn )<br> q = p + mn
cupoosta [38]
It would be your first answer because since the MN is a positive you have to subtract it to move it to P and you solved for Q

Masja [62]

Answer:

1245

Step-by-step explanation:

Distribute the number 3 to each of the numbers in the second set of parentheses. Be careful to remember to add zeros to the number depending on which place holder the number is in.

Demonstration:

3 × 400

3 x 10

3 x 5

After solving each equation, add the total

1200 + 30 + 15 = 1245
