The answer is Letter B - $2,850.
Multiply the number of shares to their respective costs per share. Add the results. Get the total number of shares then divide it by 10 before multiplying the result to 4.25. Add the product to the previous total.
Hyren Airlines: 92 shares x 13.70 = 1260.4
Giaco Household Goods: 130 x 3.28 = 426.40
Iwad Records: 126 x 8.06 = 1015.56
Total: 2,702.36
Commission: (92 + 130 + 126) 348 shares / 10 shares = 34.8 x 4.25 = 147.90
Total: 2702.36 + 147.90 = 2,850.26 or 2,850
We know that
Inverse Variation is a<span> relationship between two variables in which the product is a constant
so
let
x------> a pitch of a musical instrument
y------> </span><span>the wavelength
x*y=k
find the value of k
for x=</span><span>220 hertz y=3 ft
</span><span>x*y=k
220*3=k
k=660
</span>for x=165 hertz y=4 ft
x*y=k
165*4=660
k=660<span>
the answer part a) is
</span><span>the type of variation between pitch and wavelength is an inverse variation
</span>
part b) <span>What is the pitch when the wavelength is 5 feet?
x=?
y=5 ft
k=660
x*y=k------> solve for x
x=k/y----------> x=660/5-----> x=132 hertz
the answer Part b) is
132 hertz</span>
Answer:
1.48 m
Step-by-step explanation:
mean height of 14 boys is 1.56 m, so their total height is 14 * 1.56 = 21.84 m
mean height of 32 students is 1.515 m, so their total height is 48.48
48.48 - 21.84 = 26.64 (total height of the girls)
mean height of the girls is 26.64/18 = 1.48 m
