vladimir1956 [14]

Answer:

Lowest score needed=4.92

Step-by-step explanation:

Using the standard normal distribution table we find the value of standard normal deviate corresponding to area of 15%

For area of 15% we have Z= -1.04

Thus we have

Z=\frac{X-\overline{X}}{\sigma }\\\\\therefore X=\sigma Z+\overline{X}\\\\

Applying values we get

X=-1.04\times 2+7\\\\X=4.92

Thus lowest score needed = 4.92

Kayla’s dollhouse has 15.15 square feet downstairs and 6.45 square feet upstairs. What is the estimated total area if you round
Hitman42 [59]

  • The area of Kayla's dollhouse upstairs = 15.15 square feet

  • The area of Kayla's dollhouse downstairs = 6.45 square feet

  • To find the estimated Total area of Kayla's dollhouse, we would apply the Addition Operation

  • The estimated total area is calculated using the formula :

Area of the dollhouse upstairs + Area of the dollhouse downstairs

Rounding to the decimals to the nearest tenth

  • The area of Kayla's dollhouse upstairs to the nearest tenth = 15.2 square feet

  • The area of Kayla's dollhouse downstairs to the nearest tenth = 6.5 square feet

15.2 square feet + 6.5 square feet = 21.7 square feet

The estimated total area of Kayla's dollhouse is  21.7 square feet
