The  lowest score you can earn on the next test and still achieve an average of at least an 88 is 107

<h3>Mean of data</h3>

Mean is the average of numbers.

Mean = sum of data/sample size

Let the lowest score be "x" such that;

Mean = 74+78+90+91+x/5

88 =  74+78+90+91+x/5

88(5) = 74+78+90+91+x

440 = 74+78+90+91+x

440 = 333 + x

x = 440 - 333

x = 107

Hence the  lowest score you can earn on the next test and still achieve an average of at least an 88 is 107

Eden just bought a trough in the shape of a rectangular prism for her horses. She needs to know what volume of water to add to t
notsponge [240]

The volume of the trough is V(w) = w³ + 20w² - 429w and the rate of change of the volume over a width of 38 inches to 53 inches is 4695 in³/in

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let w represent the width, hence:

length = w + 33, height = w - 13

Volume (V) = w(w + 33)(w - 13) = w³ + 20w² - 429w

V(w) = w³ + 20w² - 429w

Rate of change = dV/dw = 3w² + 40w - 429

When w = 38, dV/dw = 3(38)² + 40(38) - 429 = 5423

When w = 53, dV/dw = 3(53)² + 40(53) - 429 = 10118

Rate = 10118 - 5423 = 4695 in³/in

The volume of the trough is V(w) = w³ + 20w² - 429w and the rate of change of the volume over a width of 38 inches to 53 inches is 4695 in³/in
