Answer: 9.8 inches

Step-by-step explanation:

Since x = 2 inches

Rainfall in April = x inches = 2 inches

Rainfall in May = x + 1.3 = 2 + 1.3 = 3.3 inches

Rainfall in June = 2x + 0.5 = 2(2) + 0.5 = 4.5

Total rainfall = 2 + 3.3 + 4.5 = 9.8 inches

Suppose the line of best fit is being found for some points that have an r-value of 0.769. If the standard deviation of the x-co
jeyben [28]

r value i.e Correlation between x value and y value = 0.769

A_{x}=Standard deviation of the x-coordinate = 5.508

 A_{y}=Standard deviation of the y-coordinate = ?=k

Slope of line is given by formula

If slope of line is m, then

m = r\times \frac{ A_{x}}{A _{y}}

m= 0.769 \times \frac{k}{5.508}

Substitute the value of k, i.e Standard deviation of the y-coordinate and then you can get the slope of line to three decimal places.

a shopkeeper bought a dress for 750 and sold it ,making a loss of 50 .calculate the percentage loss made on the sale​
kiruha [24]

Answer:

<u><em>He made a loss of 6.67%</em></u>

Step-by-step explanation:

Loss percentage =  \frac{Loss}{Cost price} * 100

Loss = 50

Cost price = 750

Hence, Loss percentage=

\frac{50}{750} *100

=\frac{20}{3} = 6.66 %

He made a loss of 6.6666%.

This amount can be rounded up to 6.67%

<em>Hope this helps.</em>

Figure 1: find the surface area: [(3 x 2 1/4) x 2] for the top and bottom. [(4 1/2 x 2 1/4)x 2] for the left and right squares. [(3 x 4 1/2) x 2] for the front and back. Which should be 20 1/4 + 27 + 13 1/2 = 60 3/4 m. The area is 4 1/2 x 3 x 2 1/4 = 30 3/4 m.
