Answer:
a

b

c

Step-by-step explanation:
Generally the size of the sample sample space is mathematically represented as

Where N is the total number of objects available and r is the number of objects to be selected
So for a, where N = 19 and r = 8



For b Where N = 25 and r = 3



For c Where N = 23 and r = 2



Answer:
<h2>$36.00</h2>
Step-by-step explanation:
$12.00 - the total cost of 4 of equally priced gloves
$12.00 : 4 = $3.00 - the cost of 1 glove
The cost per glove is increased by $1.00. Therefore new cost of 1 glove is
$3.00 + $1.00 = $4.00
The total cost of 9 of gloves at the new price:
9 × $4.00 = $36.00
Answer:
AD=2
Step-by-step explanation:

The missing coordinates of the parallelogram is (m + h, n).
Solution:
Diagonals of the parallelogram bisect each other.
Solve using mid-point formula:

Here 


<u>To find the missing coordinate:</u>
Let the missing coordinates by x and y.
Here 



Now equate the x-coordinate.

Multiply by 2 on both sides of the equation, we get
m + h = x
x = m + h
Now equate the y-coordinate.

Multiply by 2 on both sides of the equation, we get
n = y
y = n
Hence the missing coordinates of the parallelogram is (m + h, n).
Answer:
42
Step-by-step explanation:
One angle of a regular pentagon = 108°
One angle of a regular hexagon = 120°.
One angle of a square = 90°
∴ ∠BAC = 360 – (108 + 20 + 90) 360 – 318 = 42°
