Iris weighed 5 large watermelons from her garden. Here are the weights in pounds. 17,11,21,24,22 what is the mean weight
Rufina [12.5K]

Answer:

Mean weight = 19 pounds

Step-by-step explanation:

From the question given above, the following data were obtained:

17, 11, 21, 24, 22

Number of data (n) = 5

Mean weight =?

The mean of a set of data is the value obtained by adding all the data together and dividing the result obtained by the total number of data. Thus, the mean can be obtained as follow:

Summation of data = 17+ 11 + 21 + 24 + 22

= 95

Number of data = 5

Mean = Summation of data / Number of data

Mean = 95 / 5

Mean weight = 19 pounds

Therefore, the mean weight of the data is 19 pounds

Rachel ate 1 4/6 brownies, and brandy ate 6/7 of a brownie. how many brownies did they eat altogether?​
In-s [12.5K]

Answer:

53/21 OR 2 11/21

1) 139.15m^2

Step-by-step explanation:

2) area of a rectangle formula : LW

Area of a triangle:(bh)/2

Area of a semi circle:( Pi*r^2)/2

Area of a square: S^2

Area of figure one:

Lw+(b1*h1)/2+(b2*h2)/2

8*4+(2*3)/2+(3*3)/2

32+3+4.5=39.5

Area of fig 2:

S^2+(pi*r^2)/2

10^2+(3.14*5^2)/2

100+78.5/2

100+39.25=139.25

The freezing point of water is 0 C. Scientists use positive numbers to show temperatures above the freezing point water and nega
inn [45]

Answer:

The -18°C temperature as the freezing point of maple syrup means that the temperature at which maple syrup changes from liquid to solid (that is, freezes) is 18° below the freezing point of water.

Step-by-step explanation:

It is explained that the freezing point of water is used as the standard or reference point to calibrate the Celsius scale.

The scientists use 0°C to represent the freezing point of water and subsequently use positive numbers to indicate temperatures above the freezing point of water and negative numbers to indicate temperatures lower than the freezing point of water.

So, a temperature/freezing point of -18°C simply means that the temperature/freezing point is 18° lower than the freezing point of water.

Hope this Helps!!!
