In Ms. Dole's class, students received grades of 87, 72, 99, 93, and 84 on yesterday's quiz. What was the mean of the quiz grade
Naddika [18.5K]
Hello!

The mean is the average of the numbers

To find the average you add them all up and divide the sum by the amount of numbers added

87 + 72 + 99 + 93 + 84 = 435

Divide the sum by the amount of numbers added

435 / 5 = 87

The answer is 87

Hope this helps!

Sergio works at a bakery and needs to cover
Elan Coil [88]

Answer:

The surface area that Sergio needs to frost on each cake is 3,238 square centimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The surface area of the cylindrical cake is equal to the lateral area plus the area of the top of cylinder (remember that the bottom of the cake does not need frosting)

so

SA=\pi r^{2}+2\pi r h

we have

r=40.2/2=20.1\ cm ---> the radius is half the diameter

h=15.6\ cm

\pi=3.14

substitute the given values

SA=(3.14)(20.1)^{2}+2(3.14)(20.1)(15.6)

SA=1,268.59+1,969.16\\SA=3,237.75\ cm^2

Round up to the  nearest whole number

SA=3,238\ cm^2

therefore

The surface area that Sergio needs to frost on each cake is 3,238 square centimeters
