Answer:

B. 5x^2 y^5 z

Step-by-step explanation:

Given expression is,

\sqrt[3]{125x^6y^{15}15z^3}

=\sqrt[3]{(5^3)(x^2)^3(y^5)^3(z)^3}      ( (a^{mn}=(a^m)^n )

=\sqrt[3]{(5x^2 y^5 z)^3}       ( a^m.b^m=(ab)^m )

=((5x^2 y^5 z)^3)^{\frac{1}{3}}    ( \sqrt[m]{a}=a^{\frac{1}{m}} )

=(5x^2 y^5 z)^{3\times {\frac{1}{3}}

=(5x^2 y^5 z)^1

=5x^2 y^5 z

Hence, option B is correct.

The accompanying data resulted from an experiment in which weld diameter x and shear strength y (in pounds) were determined for
saul85 [17]

Answer:

y hat = 2114.20 + 18.96x

Step-by-step explanation:

Given the least square regression model equation:

y hat = -959.00 + 8.60x

weld diameter x ; shear strength y (in pounds)

1 lb = 0.4536 kg

To express shear strength y in kilogram:

y is multiplied by 0.4536

(y hat × 0.4536) = -959.00 + 8.60x

Divide both sides by 0.4536

(y hat × 0.4536) / 0.4536= (-959.00 + 8.60x) / 0.4536

y hat = 2114.1975 + 18.959435x

y hat = 2114.20 + 18.96x
