Answer:
Computer is $866
Printer is $433
Step-by-step explanation:
We can form two equations given our variables:
Let's assume the computer=C and the Printer=P.
1) C+P=1299
2) 2P=C
Now we just plug in the 2nd equation into the 1st.
(2P+P)=1299
3P=1299
P=1299/3
P=433
Now that we know the value of the printer, we can subtract that from the total price:
1299-433=866
C=866

There are 15 tiles in a bag. Of these, 7 are purple, 5 are black and the rest are white.
Event A = drawing a white tile on the first draw
Event B = drawing a purple tile on the second draw
If two tiles are drawn from the bag one after the other and not replaced, what is P(B|A) expressed in simplest form?
A. 1/5
B. 1/3
C. 7/15
D. 1/2
Answer: C.
Step-by-step explanation: If I am wong I am sorry !
Probability of drawing two tiles from the bag one after the other and not replaced that is P(B/A) is equals to [tex]\frac{1}{2}[/tex].
What is probability?" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Conditional probability ' P(B/A)' = P(A∩B) / P(A)
According to the question,
Total number of tiles = 15
Number of while tiles represented by 'A' = 3
Number of purple tiles represented by 'B' = 7
Number of black tiles= 5
Total number of outcomes = 15 × 14
= 210
Favourable outcome for A = 3 × 14
= 42
Favourable outcomes for A∩B = 3 × 7
= 21
Probability of A
'P(A)' = [tex]\frac{42}{210}[/tex]
Probability of A∩B
'P(A∩B)' = [tex]\frac{21}{210}[/tex]
Substitute the value in the conditional probability we get,
Probability for P(B/A) = [tex]\frac{\frac{21}{210}}{\frac{42}{210} }[/tex]
= [tex]\frac{1}{2}[/tex]
Hence, Option(D) is the correct answer.

John has a part time job.
He is paid £6.80 per hour.
This week he worked for 9 1/2 hours.
Work out John's total pay for this week.
Step-by-step explanation:
Given,
John get paid for working per hour = £6.80
he worked this week = 9 1/2 hr can be written as 19/2 hr.
so, total amount he will get paid for working 19/2 hr
= 19/2 × 6.80
= 19 × 3.40 = 64.60 or 64.6
therefore, John's total.pay of this week is £64.6.

Deion is making sandwiches for a picnic. He uses 2 slices of cheese to make each sandwich,
and he has a package of cheese with 24 slices. How many sandwiches can Deion make before
he runs out of cheese?
answer quickly please!
Answer:
12 sandwiches
Step-by-step explanation:
We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:
24 / 2 = 12
Therefore, Deion can make 12 sandwiches before he runs out of cheese.

Answer:
C See below
Step-by-step explanation:
Use FOIL to find answer
First, Outer, Inner, Last

Outer 2x times 5 = - 10x
Inner 5 times 2x = 10x
Last 5 times 5 = - 25

19 people use the gym and the track.
6 people use all three facilities.
A person is selected at random.
What is the probability that this person doesn't use any facility?
The probability that this person does not make use of the facility is 7/130
How to solve for the probability61+68+60 - 25-28-19 + 6
= 123
The total number of person in the sport center is given as 130
We have 130 - 123 = 7
This means that there are a total of 7 persons that do not make use of this facility.
Hence the probability of a person not using the facility is 7/130

A triangle is shown
What is x?
What is y?
What is z?
Answer:
x = 44
y = 136
z = 136
Step-by-step explanation:
The angles of a triangle have to add up to 180°
54 + 82 + x = 180
136 + x = 180
x = 44
We know that y and z are vertical angles, so they have the same measurements.
Also, x and the other angle across from it are also vertical angles.
88 + 2n = 360
2n = 272
n = 136
Therefore,
x = 44
y = 136
z = 136

PLEASE HELP ME ASAP.
Step-by-step explanation:
anything whole or complete is designated as 100%.
what is x% of that whole ?
well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.
100×f = x
f = x/100
whole × f = x% of the whole
so, when we are looking for 5%, what did that mean ?
it means that x = 5, and f = 5/100.
therefore, 5% of $13 is
13 × 5/100 = 65/100 = 0.65
so,
basic cost = $13
tax rate = 5%
tax amount = $0.65
and
basic cost = $13
tax amount = $0.65
total cost = 13 + 0.65 = $13.65
as 5/100 = 0.05
we have seen that the tax amount is simply $13×0.05
and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total
total cost = $13×(1+0.05) = $13×1.05 = $13.65
so, the decimal factor we can use directly without going through all the detail above is : 1.05
