The legs are 12 cm each, so the hypotenuse is√(144+144)=12√2☺☺☺☺
Answer:
75
Step-by-step explanation:
45*1/3=15
15*5=75
Answer:
The mashi e drilled down 45 feet. So -45
Step-by-step explanation:
72 = 24h
X = 15h
24x = 1080
x = 45
Answer:
(155.301 ; 159.299)
Step-by-step explanation:
Xbar = 157.3
Sample size, n = 234
Population standard deviation, σ = 15.6
The confidence interval :
Xbar ± standard Error
Standard Error = Zcritical * σ/√n
Zcritical at 95% = 1.96
Standard Error = 1.96 * (15.6/√234) = 1.999
Lower boundary : 157.3 - 1.999 = 155.301
Upper boundary : 157.3 + 1.999 = 159.299
(155.301 ; 159.299)
The first one:
5v + 3 = 5v - 5
Subtract 5v from both sides ->
3 = -5
This isn't true so that means there are no solutions...
