A banker was analyzing credit scores of mortgage clients when he accidentally deleted one of his client's scores from his data table. He already calculated the mean, standard deviation, and [tex]$z$[/tex] scores.
Mean [tex]$=780$[/tex]
[tex]$\sigma \approx 28$[/tex]
[tex]$z_x=1.07$[/tex]
[tex]$z_x=\frac{x-\mu}{\sigma}$[/tex]
Which equation can you use to calculate the missing credit score?
[tex]$1.07=\frac{x-780}{28}$[/tex]
[tex]$780=\frac{x-28}{1.07}$[/tex]
[tex]$28=\frac{-x-107}{780}$[/tex]
Answer (3)
A 1 = 3 ∗ 5 = 15 3.5 ∗ 1.4 = 4.9 5 ∗ 1.4 = 7 A 2 = 4.9 ∗ 7 = 34.3 15 34.3 ∗ 100% = 228. ( 6 ) % 228. ( 6 ) % − 100% = 128. ( 6 ) %
128.(6)%
i think this is the ans ;
The area of the rectangle increases from 15 square units to 29.4 square units when enlarged by a scale factor of 1.4. The increase in area is 14.4 square units, leading to a percent increase of 96%. Therefore, the area increases by 96%.
