If you have a graphing calculator (such as a TI-84), you can use the normalcdf feature by clicking on the blue "2nd" button, then the "vars" button and then choice 2. Since you are finding the proportion of hybrids that get over 61 mpg, the lower bound is 61, the upper bound is infinity (you can type in 99999), the mean is 57, and the standard deviation is 3.5. So... normalcdf(61,99999,57,3.5) = .1265. This means that 12.65% of the hybrids get over 61 mpg.
15 red, 13 white, and 10 blue. I divided 38 by three and just sorta guessed from there if that makes any sense :P hope I helped!
I believe the answer would be 6 because 7x2=14 so 3 cantaloupes x 2= 6
It helps to draw diagrams when working through problems like this.
Given a rectangular prism (the suitcase), drawing a diagonal through its side will give you two right triangles. You can use the Pythagorean Theorem (a² + b² = c², where c is the hypotenuse of a right triangle) to find the length of the unknown side. The hypotenuse of the triangle is the diagonal since it is the longest side, and it is opposite the right angle.
a² + b² = c²
a² + 24² = 26²
a² + 576 = 676
a² = 100
a = 10 in
Remember that this is only the side length of the triangle. To find the amount of material needed to cover one side of the suitcase, we need its area. We can find the area using the formula for area of a rectangle: A = bh.
A = bh
A = 10*24
A = 240 in²
