Answer:
13/28
Step-by-step explanation:
Total number of students = 28
Number of students that play basketball = 14
Number of students that play baseball = 19
Number that play neither sport = 5
Number of students playing sports = 28 – 5 = 23
Number of students playing both basketball and baseball = 14 + 19 – 23 = 10
Number of students that play only basketball = 14 – 10 = 4
Number of students that play only baseball = 19 – 10 = 9
Number of students playing basketball or baseball = 4 + 9 = 13
P(a student chosen at random plays basketball or baseball) = 13/28
Step-by-step explanation:
using the formula :
2.d.s = V²-Vo²
2(-0.15) (60) = V² - (8.55)²
-18 = V² - 73.1
V² = 73.1 - 18
V² = 55.1
=> V = √55.1 = 7.4
so, the velocity when she ends the race =
7.4 m/s
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys
A good place to start for this question is to define the properties of the geometric terms you are given.
Quadrilaterals have four straight sides.
Parallelograms are quadrilaterals that have two pairs of parallel sides. The opposite sides and opposite angles are congruent. Squares, rectangles, and rhombuses are examples of parallelograms.
Trapezoids are also quadrilaterals. They have only one pair of parallel sides.
So we're looking to see if there are any four-sided shapes that can be made with no parallel sides. The attached picture shows an example of a quadrilateral that is not a parallelogram and is not a trapezoid. Based on these properties of polygons, the correct answer is B.
Answer:
The probability of failure of trial 11 is 
Step-by-step explanation:
Generally one the attributes of a binomial experiment is that the probability of success and failure is constant every trial so given from the question that the probability of success is 0.84 for trial 7 , then the probability of failure of trial 7 will be evaluated as

=> 
And from the attribute stated above the probability of failure of trial 11 is
