Stephanie needs to cover her yard with 4103/4ft2 of soil she has enough for 125 ft2 in one bag and 65 ft 2 in another bag how mu

Evgen [1.6K]

Answer:

Stephanie requires 835.75 square feet more amount of soil to cover her yard.

Step-by-step explanation:

Given:

Total square feet of yard she need to cover with soil = $\frac{4103}{4}\ ft^2$

$\frac{4103}{4}\ ft^2$ can be rewritten as 1025.75 square feet.

Total square feet of yard she need to cover with soil = $1025.75\ ft^2$

Amount of soil in one bag = $125\ ft^2$

Amount of soil in other bag = $65\ ft^2$

Total Amount of soil she has is equal to sum of Amount of soil in one bag and Amount of soil in other bag.

Framing the equation we get;

Total Amount of soil she has= $125+65 = 190\ ft^2$

Now We need to find the Amount of soil she required more to cover the yard.

Amount of soil she required more is equal to difference of Total Amount of soil she has and Total square feet of yard she need to cover with soil.

Framing the equation we get;

Amount of soil she required more = $1025.75-190= 835.75\ ft^2$

Hence Stephanie requires 835.75 square feet more amount of soil to cover her yard.

A real estate builder wishes to determine how house size is influenced by family income, family size, and education of the head

OlgaM077 [116]

Answer:

see explaination

Step-by-step explanation:

1) Lets form the regression equation from the data results

Size = -1.633+ 0.4485*FamilyIncome + 4.2615*FamilySize - 0.6517*Education

-1.633+ 0.4485*40+ 4.2615*4 - 0.6517*13 =24.88

2) For the model to be reasonable, we must check the significant F stat from the anova table( see attachment)

From the table at attachment we can deduce; as the significant F is less 0.01 , we can safely conclude that the model is signifcant

3) all variables that have a p value less than 0.01 can be safely removed from the model as they do not contribute sigificantly from the model

so education can be removed from the model

MatroZZZ [7]

Answer:

The median is 61.

Step-by-step explanation:

To find the median, you take the number that is numerically in the center of the data set. Since this set has two numbers like that (60 and 62), you find the mean of those two numbers. This leaves us with 61.

Andy estimated that he would need 73 feet of lumber for a tree house project. He later found that the actual amount of lumber ne

sweet-ann [11.9K]

Answer:

17.74%

Step-by-step explanation:

The formula for percent error is given as:

|Estimated value - Actual value|/Actual value × 100

From the above question:

Estimated value = 73 feet

Actual value = 62 feet

Hence,

Percent error = |73 - 62|/62 × 100

= 11/62 × 100

= 17.741935484%

Approximately , percent error = 17.74%

Therefore, the percent error of Andy's estimation is 17.74%
