Using a line of best fit, the predicted tsunami speed for the following depths is given by:

a. 1151 km/h.

b. 572 km/h.

c. 130 km/h.

d. 122 km/h.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (depth, velocity) are given by:

(7000, 943), (4000, 713), (2000, 504), (200, 159), (50, 79), (10,36)

Inserting these points in the calculator, the velocity in function of the depth is:

v(d) = 0.12879d + 121.03448

Hence, the velocities are given as follows:

a. v(8000) = 0.12879 x 8000 + 121.03448 = 1151 km/h.

b. v(3500) = 0.12879 x 3500 + 121.03448 = 572 km/h.

c. v(70) = 0.12879 x 70 + 121.03448 = 130 km/h.

d. v(5) = 0.12879 x 5 + 121.03448 = 122 km/h.

A rectangular banner covers an area of 2 7/8ft2. The length of the banner is 3/4ft. What is the width of the banner in ft?

hichkok12 [17]

Answer:

Width of the rectangular banner is $3\frac{5}{6}$ ft.

Step-by-step explanation:

Area of the rectangular banner = $2\frac{7}{8}$ square feet

= $\frac{23}{8}$ square feet

Area of rectangle is given by,

Area = Length × Width

Length of the banner = $\frac{3}{4}$ feet

From the formula,

$\frac{23}{8}=\frac{3}{4}\times W$

W = $\frac{\frac{23}{8} }{\frac{3}{4} }$

= $\frac{23}{8}\times \frac{4}{3}$

= $\frac{23}{6}$

= $3\frac{5}{6}$ ft

Therefore, width of the rectangular banner is $3\frac{5}{6}$ ft
