Answer: B
Step-by-step explanation:
5% of 500 is 25, 25 x 5 is 125, 125 + 500 is 625
The exterior angle is 180-135= 45 degrees.
The number of sides=
The number of sides= 8 sides
This is an octagon
Answer:
Probability is 0.0174
Step-by-step explanation:
Given data
mean = 140
variance = 25
no of sample n = 49
to find out
probability of the sample
solution
standard deviation is
standard deviation =
standard deviation = 5
we mean by more than 1.7 millimeters so
mean (X1) = mean + 1.7 or mean - 1.7
so probability = X1 -mean/ ( standard deviation / )
probability = 140 -1.7 -140 / ( 5 / )
probability = - 1.7 / 35 = -0.048
probability = 140 + 1.6 -140 / ( 5 / )
probability = 1.7 /35 = 0.048
so required probability is i.e
= P(X1 < mean - 1.7 ∪ X1 > mean + 1.7 )
= 1 - P(mean -1.7 < X1 < mean +1.7 )
= 1 - P(-0.048 < X1 < 0.048 )
= 1 - 0.9826
= 0.0174
so required probability is 0.0174

C.
cos(45)=x/
x=8
A.
x= 8 its an isosceles so c=a
B.
sin(30)=8/x
x= 16
D.
cos(30)=x/16
x=8
Set the two functions equal to each other and solve for x
x^2-6x+8=x-2
-x. -8 -x-8
x^2-7x=-10
x(x-7)=-10
x=-10 x-7=-10
+7 +7
x=-10 & x=-3
