You are correct!
Step 1:Write what you know
Madeline's Height: 6 ftMadeline's Shadow: 108 in
Friend's Height: X (we use X as a variable because his height is unknown)Friend's Shadow: 108 in - 1.5 ft 108 in - 18 in 90 in
Step 2:Set up proportions
6 x----- = -----108 90
Step 3:Cross Multiply & Solve
108x = 540x = 5 ft tall
Answer:
The supplier is less accurate than they have claimed
Step-by-step explanation:
Given that:
95% confidence interval of supplier's claim :
(20.45, 21.05)
Mean = (20.45 + 21.05) /2 = 41.5 / 2 = 20.75
Error margin = (upper bound - mean) = 21.05 - 20.75 = 0.30
95% confidence interval of your sample :
(20.48, 21.02)
Mean : (20.48 + 21.02) /2 = 41.05 / 2 = 20.75
Error margin = (upper bound - mean) = 21.02 - 20.75 = 0.27
0.3 > 0.27
From the calculations made, the mean are the same, but the error margin of supplier is higher, thus it could be concluded that the supplier is less accurate than they have claimed
Answer:
C. y = [x] - 6
Step-by-step explanation:
The point that lies on the x-axis is sitting at (6,0), 6 being x and 0 being y, when you relpace the [x] with 6 and do the equation, you will get 0, which is what y happens to be equal to.
x = 6
y = [6] - 6 = 0
y = 0
