X 1 2 3 4
p(x) 0.40 0.20 0.15 ?
If the items are only 4. The total of the probability must be 1 or 100%
1 - 0.40 - 0.20 - 0.15 = 0.25
The probability of 4 is 0.25.
Answer:
The answer is <u>D. quadrilaterals</u>
Step-by-step explanation:
- <u><em>All </em></u><u><em>trapezoids </em></u><u><em>are squares. If a shape is a square, then it is also a rectangle and a rhombus. A</em></u><u><em> trapezoid </em></u><u><em>is a </em></u><u><em>quadrilateral </em></u><u><em>with exactly one set of parallel sides</em></u>

This is the concept of sequences and series. To solve the question we proceed as follows:
2] T=-4n-3
to get the 11th term we substitute n=11 in the expression and simplify. Thus, plugging in n=11 we obtain:
T=-4(11)-3
T=-44-3
T=-47
thus the 11th term is -47
3] General term is T=n²-1. The 7th term will be evaluated as above:
plug in n=7 in the expression and simplify:
T7=7²-1
T7=49-1
T7=48
thus the 11th term is 48
4] General sequence is T=1/3n². The term will be evaluated as follows:
plug in n=3 in the expression and simplify:
T3=1/(3×3²)=1/27
Thus the 3rd term is 1/27
