A = e; b = 2 f; n = 10.
The fourth term is:
T 4 = T (3+1) = ( 10 * 9 * 8 ) / ( 3 * 2 * 1 ) * e^7 * ( 2 f ) ^3 =
= 120 * e^7 * 2^3 * b^3 =
= 120 * 8 * e^7 * b^3 =
= 960 * e^7 * b^3
Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° = =
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x = ≈ 88.2
Correct histogram: top-right corner
Step-by-step explanation:
The picture is missing: find it in attachment.
A histogram is a type of plot representing data divided into classes. The classes can be represented using bars with same width: if so, the height of each bar is proportional to the number of data inside each class.
Here by looking at the table in the figure, we notice that:
- There are 3 data in the 800-899 class: 805, 805, 872
- There are 5 data in the 900-999 class: 910, 919, 923, 950, 989
- There are 8 data in the 1000-1099 class: 1004, 1010, 1020, 1051, 1056, 1085, 1094, 1098
- There are 6 data in the 1100-1199 class: 1108, 1128, 1133, 1150, 1150, 1187
- There 3 data in the 1200-1299 class: 1209, 1220, 1298
Therefore, the correct histogram representing the set of data is the histogram on the top-right corner, which has respectively columns of height 3, 5, 8, 6 and 3.
