This is the answer -1/6, -3, 1/6, .5,
Answer:
We use addition because -16 is negative, and we need to cancel out its value so we add 16 to both sides, leaving 0+x, or x, on the left and combining like terms on the right.
Step-by-step explanation:
Answer:
y = 2, x = 16
Step-by-step explanation:
x = 10 + 3y
xy = 32
Solve.
y = 2.
x = 16
The percent of runners between these two times is 47.72.
We find the z-scores associated with each end of this interval using the formula
z=(X-μ)/σ
For the lower end,
z=(4.11-4.41)/0.15 = -0.3/0.15 = -2
Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this score is 0.0228.
For the upper end:
z=(4.41-4.41)/0.15 = 0/0.15 = 0
Using a z-table we see that the area to the left of, less than, this score is 0.5000.
We want the area between these times, so we subtract:
0.5000-0.0228 = 0.4772
This corresponds with 47.72%.
Answer:
122°
Step-by-step explanation:
The formula for finding the sum of all angles in a polygon is:
(n-2) * 180°
n is the number of angles
Here n = 7, so the sum of all angles is
(7-2) * 180° = 900°
x = 900 - 128 - 130 - 120 - 115 - 145 - 140 = 122°
Make me the brainliest ;)
