A box of photographs contains 13 wedding photographs 4 vacation photographs and 8 holiday photographs one is randomly selected what is the probability that the photograph is a holiday photograph given that it is not a wedding photograph
The probability that a randomly selected photograph from the box is a holiday photograph, given that it is not a wedding photograph, is 2/3 or approximately 0.67.
The question involves calculating the probability of drawing a holiday photograph from a box, given that the photograph is not a wedding photograph. First, we determine the total number of non-wedding photographs, then we find the probability that a photo selected is a holiday photograph from that subset.
There are 13 wedding photographs, 4 vacation photographs, and 8 holiday photographs. Given that we're not selecting a wedding photograph, we're only considering the vacation and holiday photographs, which total 4 + 8 = 12 photographs. The event of selecting a holiday photograph then has 8 favorable outcomes (since there are 8 holiday photographs).
The probability that the photograph is a holiday photograph given that it is not a wedding photograph is calculated by dividing the number of holiday photographs by the total number of vacation and holiday photographs:
Probability = Number of holiday photographs / Total number of non-wedding photographs = 8 / 12 = 2/3 or approximately 0.67
how do we calculate QS? given that SQT and RPT are similar. thank you
since they are similar RT is similar to ST and PR is similar to QS
find the ratios
7/6 = x/9 cross multiply 7*9 =63
63/6 = 10.5
so QS = 10.5

You brought 1.5 dozen bagels to school. A dozen bagels cost $5.98. You used a coupon that took $1.00 off of the total. How much did you pay for the bagels?
1 dozen cost 5.98
so 1.5 dozen cost : 5.98 x 1.5 = 8.97
a coupon takes $1 off the price so
8.97-1.00 = 7.97
they cost a total of $7.97
Answer:
$7.97
Step-by-step explanation:
multiply to find the total cost and then subtracting the coupon amount.

Ms. Banerjee bought a car for $22,500. The amount she paid for her new car was twice the amount she paid for her previous car, which she bought 8 years ago. Which equation shows p, the price in dollars that she paid for her previous car?
Answer:
The Equation would be P(x) = [tex]\frac{x}{2}[/tex]
Step-by-step explanation:
The Equation states that the price of the old car P is equal to half the price that she paid for her new car (x). Since she paid $22,500 for her new car, we can use the equation to figure out how much she paid for her previous car.
[tex]P(x) = \frac{22,500}{2}[/tex]
P = $ 11,250
So $11,250 is what Ms. Banerjee paid for her previous car.

What are the 3 methods for solving systems of equations?
If a system has no solution, how does it look on a graph?
A system of equations refers to a number of equations with an equal number of variables. We will only look at the case of two linear equations in two unknowns. The situation gets much more complex as the number of unknowns increases, and larger systems are commonly attacked with the aid of a computer.
A system of two linear equations in two unknowns might look like
This is the standard form for writing equations when they are part of a system of equations: the variables go in order on the left side and the constant term is on the right. The bracket on the left indicates that the two equations are intended to be solved simultaneously, but it is not always used.
