The distance formula measures the length of a line segment or the distance between two points.
The hypotenuse is one of the two sides that forms the right angle of a triangle.
The altitude of a triangle is a line segment that extends from the vertex and is perpendicular to the side opposite the vertex.
Answer:
10.34% probability that you both pick chocolate
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, it is not important if you or your friends picks first. So we use the combinations formula to find the number of desired and total outcomes.
Combinations Formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
10 are filled with chocolate, and we want to pick 2. So
Total outcomes:
The box has 30 chocolates, and 2 are picked, so:
Probability:
10.34% probability that you both pick chocolate
Letter D
A = 135°
B = 30°
cosAcosB - sinAsinB = cos(A+B)
cos(135°+30°)
cos(165°)
Answer:
0
Step-by-step explanation:
product is another word for +
decreased is another word for -
____________________________
(7 + 8) - x
so
(7+8) - 15
15 - 15
= 0
Answer:
Simplest form = 4<em>z </em>+ 21
Case 1: True, Case II: false and Case III: true
Step-by-step explanation:
18<em>z </em>- 7( -3 + 2z)
= 18<em>z</em> + 21 - 14z
= 18<em>z</em> -14z + 21
= 4<em>z </em>+ 21
So, in the above expression we have two terms. First term is 4z and second term is 21.
So the first case is true. As the expression has two terms.
The coefficient of <em>z </em>is a number which is multiplied by <em>z</em>. Therefore, Second case is false as the coefficient of <em>z</em> is 4.
The constant is a number which is not multiplied by any variable. Therefore, third case is true as the constant number in above expression is 21.
