Currently, the standard deviation is 10, because on average the cards were $10 away from the mean.

Adding another card with value $25 would decrease the standard deviation because it is closer to the mean the the current standard deviation.

The hypotenuse of an isosceles right triangle is 16 centimeters. Find the length of the 2 other sides of the triangle to the nea
scZoUnD [109]
Right triangle means we can use a^2+b^2=c^2
isosceles means 2 sides are equal legnths

the hypotenuse is normally the longest side so the equal sides are the other sides so therefore
a=b
therefor
(a^2)+(a^2)=c^2
2(a^2)=16^2
2(a^2)=256
divde both sides by 2
a^2=8
the side legnth of the other 2 sides is the square root of 8 which is aprox 2.8284271247452
but we only want the tenth so we look at the hundreths as well
2.82
round to the nearest tenth
2.8 cm is the answer of the legnths
