17/40=0.425 hard to step by step but i think this is the answer. What i did was divide 40 and 17 because 17% is the same as 17/100
hope this helped
Yintercepts are where x=0
set to zero to solve
0^2+4y^2=16
4y^2=16
divide 4
y^2=4
sqrt both sides
y=+/-2
xintercept is where y=0
x^2+4(0)^2=16
x^2+0=16
x^2=16
sdqrtboth sides
x=+/-4
yintercepts are (0,2) and (0,-2)
xintercepts are (4,0) and (-4,0)
Yes (2,5) is a solution to the system of equation
2+2 (5)=12
2+10=12
12=12
2(2)+2(5)=14
4+10=14
14=14
The mean is 50 because if half get a "100" and the other half get a "0" the mean is 50. The standard deviation is 7.07 when you plug this into the 1-VARS stats on a calculator after putting this data in L1 List data set on the calculator.
a. 50
b. 7.07
