The following information about the mean and standard deviation has been provided:

ц=25, б=3,n=20

We need to compute Pr(X⁻≥26.3).

The corresponding z-value needed to be computed is:

Z=\frac{X-u}{o/\sqrt{n} } =\frac{26.3-25}{3/\sqrt{20}  }=1.9379

Therefor, we get that

Pr(X\geq 26.3)=Pr(Z\geq \frac{26.3-25}{3/\sqrt{20} } )=Pr(Z\geq 1.9379)\\=1-0.9737=0.026

Solve the system.
Lisa [10]

Answer:

(15, 8, 7 )

Step-by-step explanation:

x - y + z = 14 → (1)

y + z = 15 → (2)

z = 7 ← value of z is given

Substitute z = 7 into (2)

y + 7 = 15 ( subtract 7 from both sides )

y = 8

Substitute y = 8, z = 7 into (1)

x - 8 + 7 = 14

x - 1 = 14 ( add 1 to both sides )

x = 15

solution is (15, 8, 7 )
