Answer:

1.9

Step by step answer

step1 finding the mean

(7+4+7+7+2+10+12+8+7+5)/10 = 6.9

step2 Difference between each data

Difference between 7 and 6.9 is 0.1

Difference between 4 and 6.9 is 2.9

Difference between 7 and 6.9 is 0.1

Difference between 7 and 6.9 is 0.1

Difference between 2 and 6.9 is 4.9

Difference between 10 and 6.9 is 3.1

Difference between 12 and 6.9 is 5.1

Difference between 8 and 6.9 is 1.1

Difference between 7 and 6.9 is 0.1

Difference between 5 and 6.9 is 1.9

step3 add all the Difference

0.1 + 2.9+0.1+0.1+4.9+3.1+5.1+1.1+1.9 = 19.4

step4 divde it by n

19.4/10 = 1.9

so the answer is 1.9

Use 1/2ab sin C formula pls
Harman [31]

Step-by-step explanation:

area =  \frac{1}{2} a.b \sin(C)  \\ from \:cosine \: rule \\  {c}^{2}  =  {a}^{2}  +  {b}^{2}  - 2a.b \cos(C)  \\ 36 = 144 + 81 - (2 \times 12 \times 9) \cos(C)  \\ 189 = 216 \cos(C)  \\  \cos(C)  = 0.875 \\ C =  \cos {}^{ - 1} (0.875) \\ C = 28.96 \degree \\ area =  \frac{1}{2}  \times 144 \times 9 \times  \sin(28.96 \degree)  \\ area = 313.8 \: sq \: units

Step-by-step explanation:

Since 39 out of 40 marbles are green, the probability of randomly choosing green is 39/40.

However, the probability becomes 100% when you look into the bag and choose a green marble. (Unless you are blind or unable to distinguish blue from green, in which case the probability remains 39/40.)
