For #1 you know that a straight line equalys 180 degrees so the look at the 3× degrees. 180-84 =96 /3= 32 degrees . x = 32
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
Answer:
n=-8
Step-by-step explanation:
n/8 - 10 = -11
add 10 to both sides
n/8=-11+10
n/8=-1
multiply eight by both sides to cancel it out to get n by itself
n/8 x 8 and -1x8
-1x8=-8
n=-8
Lets put ti this way:
P[1st serve good & wins point] = 60% * 70% = 42% = A
<span>P[2nd serve good & wins point] = 40% * 76% *57% = 17.328% = B </span>
<span>1. P[win point] = A+B = C = 59.328% <------- </span>
<span>2. P[1st serve good | win point ] = A/C = 42 / 59.328 = 0.707 or 70.7%
Please </span><span>remember that 2nd serve come into use only if 1st serve is not good</span>
