Answer:
the answer is maybe 99 i aint sure tho
Step-by-step explanation:
In statistics, the 68–95–99.7 rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within a band around the mean in a normal distribution with a width of two, four and six standard deviations, respectively; more accurately, 68.27%, 95.45% and 99.73% of the values lie .
Answer:
-2+2
Step-by-step explanation:
Since we have the value of x, 3+2
, we can plug that value into the new equation.
We would recieve (3+2
-1)/3+2
Which could simplify to -2+2
X = -1/2 (negative)
y = - 1.8 (negative)
so It's in Quadrant 3
multiply 4 by the cos(45)
4 x cos(45) = 2sqrt(2) approximately 2.828cm
so depending how you are supposed to answer, either 2 sqrt(2) or approximately 2.83 cm
