Answer:
65.93
Step-by-step explanation:
Okay, first lets convert the money.
100 ÷ 1.43 = 69.9300699301 (69.93)
69.93 - 4 = 65.93

Answer:
y=(-2/3)x+8
Step-by-step explanation:
2x+3y=24
3y=-2x+24
y=(-2x+24)/3
y=(-2/3)x+8
Answer:
93.19%
Step-by-step explanation:
We have that the mean (m) is equal to 70.4, the standard deviation (sd) 11.1 and the sample size (n) = 140
They ask us for P (x =69)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd / (n ^ 1/2))
We have all these values, replacing we have:
z = (69 - 70.4) / (11.1 / (140 ^ (1/2)))
z = 1.49
With the normal distribution table (attached), we have that at that value, the probability is:
P (z <1.49) = 0.9319
The probability is 93.19%
Cos θ = adj/hyp = 5/sqrt(5^2 + (-12)^2) = 5/sqrt(25 + 144) = 5/sqrt(169) = 5/13
Answer:
Step-by-step explanation:
If we assume the figure is a parallelogram, then the diagonals bisect each other.
XV = VZ
27 -2x = 3x +2
25 = 5x . . . . . . . . add 2x-2 to both sides
5 = x
Then the desired measures are ...
VZ = 3(5) +2 = 17
XZ = 2(VZ) = 34
