0
Step-by-step explanation:
-0.75-20+71/2+13.25
-0.75-20+15/2+13.25
-7.5+15/2
-15/2+15/2
=0
Answer:
c. 0.6
Step-by-step explanation:
A student cannot receive an A or a B simultaneously, so
.
Grade of A equals .30 and the probability of receiving a grade of B equals .30.
This means that ![P(A) = P(B) = 0.3](https://tex.z-dn.net/?f=P%28A%29%20%3D%20P%28B%29%20%3D%200.3)
The probability that a randomly selected student from this class will receive either an A or a B equals:
This is:
![P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.3 + 0.3 - 0 = 0.6](https://tex.z-dn.net/?f=P%28A%20%5Ccup%20B%29%20%3D%20P%28A%29%20%2B%20P%28B%29%20-%20P%28A%20%5Ccap%20B%29%20%3D%200.3%20%2B%200.3%20-%200%20%3D%200.6)
So the probability is 0.6, and the correct answer is given by option c.
Answer:
<h2> The answer is </h2><h2> D. 8x^2+4xy</h2>
Step-by-step explanation:
We know that the expression for the perimeter is given as
P=2l+2B
now given that the value of the width is =2x
length= 4x
and the breadth=y
P=4x+2y
let us multiply both the length and the width with 2x we have
P=2x(4x+2y)
P=8x^2+4xy
the answer is
D. 8x^2+4xy
Answer:
B
Step-by-step explanation:
No these triangles are not congruent.
<u>Left triangle</u>
Shortest side = 6 cm
Longest side = 13 cm
3rd side = unknown but < 13
<u>Right triangle</u>
Shortest side = 6 cm
Longest side = unknown but > 13
3rd side = 13 cm
Although the shortest side of both triangles is 6 cm, the longest side of the left triangle is 13 cm, whereas the longest side of the right triangle is unknown but will be more than 13 cm.
We do not know if any of the angles are congruent. If they were congruent, we would expect to see this marked by the same angle line(s) on each triangle.
