To find the probability, you write a fraction with the number of expected outcomes to total possible number of outcomes.
a) Red - 25/100
b) Purple -55/100
c). There is a 25% or 1 in 4 chance to select a red bulb and a 55% or 5 in 11 chance of selecting a purple bulb.
Perimeter is adding all 4 sides together.
To find the length and width divide total perimeter by 2:
21 / 2 = 10.5
We now know the length of 1 side and the width of 1 side need to equal 10.5.
Since the original piece was a square we also know the width needs to equal 1/2 of the length.
So we have L + 1/2L = 10.5
Add the common terms 1 L + 1/2 L = 1 and 1/2 L
To Find L divide 10.5 by 1-1/2, which equals 7
To find the width subtract 7 from 10.5, which equals 3.5
So the paper is now 3.5 inches by 7 inches.
Answer:
11 is 150
12 is 168 lectures and 70 professers
Step-by-step explanation:
<span>In
the given number : 4 083 817. Find the 3 digit which is placed in the unit
period.
=> The unit period is the digit that is placed in the ones place of the
number or the first digit on the right.
=> 7 is the unit period
=> 3 is the another unit period
=> 4 is the another unit period.
Thus, 4, 3 and 7 are the 3 digits placed in the unit period of the given
number.</span><span>

This is the concept of applications of linear equations; suppose you need x number of type A and y number of type be to make the profits required;
Total number of printers will be:
x+y=120....i
Total amount made will be:
24x+18y=2340....ii
thus solving equations i and ii by substitution we shall have:
x+y=120
x=120-y
thus substituting the above in equation ii we get:
24(120-y)+18y=2340
2880-24y+18y=2340
putting like terms together we get
-24y+18y=2340-2880
540=6y
thus
y=540/2
y=90
hence;
x=120-90=30
Therefore to make the profit of $2340 you must sale 90 type A printers and 30 type B printers
