Anvisha [2.4K]

Answer:

1,75

Step-by-step explanation:

The Mosteller formula is $[tex]M=\sqrt{\frac{(172.72)(63.95)}{3600}} = 1.75$ [/tex]

We know that height is 68 inches and weight 141 pounds

We must remember that 1 inches = 2.54 cm and 1 pound 0.453 kg

This means 68 inches = 172.72 cm and 141 pounds = 63.95

We substitute on the formula

ine segment XY has endpoints X(–10, –1) and Y(5, 15). To find the y-coordinate of the point that divides the directed line segme

stiks02 [169]

X=(-10,-1)=(Xx,Yx)→Xx=-10, Yx=-1
Y=(5,15)=(Xy,Yy)→Xy=5,Yy=15
y=?
ratio=5:3→r=5/3
y=(Yx+rYy) / (1+r)
y=[-1+(5/3)15] / (1+5/3)
y=[-1+(5*15)/3] / [(3+5)/3]
y=(-1+75/3) / (8/3)
y=(-1+25) / (8/3)
y=(24) / (8/3)
y=24*(3/8)
y=72/8
y=9

Asnwer: The y-coordinate of the point that divides the directed line segment XY in a 5:3 ratio is y=9
