Answer:
294.1 pounds
Step-by-step explanation:
Step 1
We find the z score for 90th percentile
= 1.282
Step 2
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score ??
μ is the population mean = 230 pounds
σ is the population standard deviation= 50 pounds
1.282 = x - 230/50
Cross Multiply
1.282 × 50 = x - 230
64.1 = x - 230
x = 230 + 64.1
x = 294.1 pounds

Hb=3.5, hd=2.25, hb+hd=7,
From the third, we can say hb=7-hd and we are told that:
3.5hb+2.25hd=19.5 using hb found above in this equation gives you:
3.5(7-hd)+2.25hd=19.5
24.5-3.5hd+2.25hd=19.5
-1.25hd=-5
hd=4
