Answer: D) 12
Step-by-step explanation:
As you can see side A is 6 and side B is also 6 so side C must be 12
Answer:
B. .007
Step-by-step explanation:
Mean=μ=23500
Standard deviation=σ=7200
For sample of 50 students
Mean=μxbar=μx=23500
Standard deviation=σxbar=σ/√n=7200/√50=1018.23
So, the probability that mean outstanding loan for students is under $21000
P(xbar<21000)=P((xbar-μxbar)/σxbar<(21000-23500)/1018.23)=P(Z<-2.455)
P(xbar<21000)=P(Z<-2.455)
P(xbar<21000)=P(-∞<z<0)-P(0<z<-2.455)
P(xbar<21000)=0.5-0.4930=0.007
Thus, the probability that mean outstanding loan for students is under $21000 is 0.007.
Step-by-step explanation:
Let the two numbers be x and y
By the question
x + y = 87 ..... equation (I)
x - y = 65 ...... equation (II)
Now adding both equations we get
2x = 152
x = 152 / 2
Therefore x = 76
Putting x = 76 in equation i
76 + y = 87
y = 87 - 76
Therefore y = 11
The two numbers are 76 and 11.
Hope it helps :)
