Answer:
F: 48
Step-by-step explanation:
Let x be the length of the side of the cube. RQ can be expressed as a triangle consisting of a diagonal of a face of the cube and the side length x. By the pythagorean theorem, we know that a^2+b^2=c^2. So, we can express the diagonal as x^2+x^2=c^2, giving us the value of c to be 
. Now, we can once again use the pythagorean theorem to find RQ^2=2x^2+x^2=3x^2, so RQ=
=12, so x=
. To find the area of the shaded part, we multiply the length times width which gives us 
. So, the area of the shaded face of the cube is F: 48.
Subtract 2 from one number and that answer add 3, subtract 2, and add 3 again. continue doing that.all through.
Answer:
4, -3
Step-by-step explanation:
The quadratic formula is 
.
When using the formula for both the negative and positive value of the sqrt, you will get:
x = 4, -3
Answer:
3/4= 75 % of the data is greater than the first quartile in a box-and-whisker plot.
Step-by-step explanation:
75 % of the data is greater than the first quartile in a box-and-whisker plot.
The first quartile denoted by Q1 is the median of the lower half of the data set.
This means that 25% of the values lie in the first quartile and 75 % of the values lie above the first quartile.
In the box and whisker plot the longer box indicates the interquartile range whereas the sides represent the 1st and 3rd quartile. The first quartile is the region where the values start and increase to the interquartile range.
75 % means = 75/100 or 0.75 or 3/4
75/100= 15/20= 3/4
remember that a mode is a number repeated in the data set ( or the number list.
Mode: 6
