Answer:
The expected sum is $220 and the standard deviation is $65
Step-by-step explanation:
In order to get the expected sum you add the two expected sums you are given
To get the standard deviation you add the two given standard deviations
She needs 48 yards of border trims
The first step is to determine the total sum of border trims needed in feet
45 feet + 51 feet + 48 feet = 144 feet
The next step is to convert feet to yards
1 foot = 0.333333 yards
144 x 0.333333 = 48 yards

Answer:
The answer would be 6º
Step-by-step explanation:
first we know that a straight lin is always 180º
so since we know that the angle outside of the triangle is 110º we can do 180º -110º
then we get the measuerment for angle C :70º
since we dont know the measurements of the other angles but know that a full triangle is equal to 180º we make this equation
2+6x+12x+70=180
then we solve
72+18x=180
-72 -72
18x=108
/18 /18
x=6
then we plug in the x value to find the angle measurement
2+6(6)
2+36
38º
your answer is m<CAB is 38º
Answer:
The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
Step-by-step explanation:
Cross multiply:
Divide by h on both sides:
