Answer:

a≈18 cm

Step-by-step explanation:

we have given:

an angle,

the adjacent side and

we need to find:

the opposite side

we know that the definition of

tan of an angle = opp. side/ adj. side

tan 61° = a/ 10

multiply both sides by 10

10 * tan61° = a

18.04047755 = a

18 ≈ a

Answer:

-1.53 , 1.53

Step-by-step explanation:

It is basically asking you to find the percentiles. so for the bottom 6.3% you would type into your calculator 2nd, VARS, invNorm, area: .063, mean: 0, and Standard Deviation: 1 which gives you -1.53.

for the upper 6.3% you have to take 1-.063=.937 to get the upper percentile. now type into your calculator 2nd, VARS, invNorm, area: .937, mean: 0, and Standard Deviation: 1 which gives you 1.53.
