Answer:
2.5 or 2 1/2 apples.
Step-by-step explanation:
5/2 simplified will be 2.5 or 2 1/2.
If you look into it further, because Richard had 15 apples, you subtract 2 1/2 apples he gave Pam which would leave him with 12.5 or 12 1/2. But really the answer is two and a half apples.

The line f(x) = x is graphed in the xy-coordinate plane.
How does the graph of the function f(x) + 1 compare to the graph of f(x)?
Answer:
Please check the attached diagram.
Thus, we conclude that:
In the diagram,
The red line represents the parent function f(x) = xThe blue line represents the function f(x) = x+1The blue line indicates that the parent function has been shifted 1 unit upward.
Step-by-step explanation:
Let us recall some transformation knowledge.
We know that
if y = f(x), then y = f(x) + b simply means a transformation of (0, b).
In other words, if we add some constant let say 'b' in the output or y-value, the graph simply shifts upward by b units.
Given that
f(x) = x
so
f(x+1) = x+1 means the parent function f(x) = x has been shifted 1 unit upward.
Please check the attached diagram.
Thus, we conclude that:
In the diagram,
The red line represents the parent function f(x) = xThe blue line represents the function f(x) = x+1The blue line indicates that the parent function has been shifted 1 unit upward.

Answer:
81/36
Step-by-step explanation:
81/9 is 9
9 times 4 is 36
Answer:
Hi there the answer is 81/36. Hope this helps! c:
Step-by-step explanation:
First, figure out what ratio was used to make 9, 81.
You can recall that 9 x 9 = 81.
Therefore you must multiply the bottom of the fraction by 9 as well in order to create the correct ratio.
Thus, 4 x 9 = 36.

A) it is a line which intersects the y-axis at (2,2).
B) it is aligned joining the points whose x- and Y- coordinates add up to 2.
C) it is a line which intersects the x-axis at (2,2).
D) it is a line joining the points whose x- and Y- coordinates add up to 4.
Step-by-step explanation:
so x+y=2
a line would have to go 0,2 2,0
so the answer would be D
Find each angle measure in the triangle.
Answer:
30, 60, 90
Step-by-step explanation:
since there are 6 x's in total, and there are a total of 180 degrees in any triangle, we do 180/6= 30
so now we know x=30, 2x=60, and 3x=90
Which are the intercepts of the equation y+2=4(x+1) ?
Answer:
x-intercept is ([tex]- \frac{1}{2}, 0[/tex]) and y-intercept is ([tex]0, 2[/tex])
Step-by-step explanation:
How do we find the y-intercept of a function?We solve the equation when x=0. Let's try that with [tex]y+2=4(x+1)[/tex]
First, let's simplify it so that it resembles [tex]y=mx+b[/tex] more noticeably
[tex]y = 4x + 4 - 2 \\y = 4x + 2[/tex]
Now let's plug in 0 for x to find the y-intercept:
[tex]y = 4\cdot 0 + 2\\y = 2[/tex]
How do we find the x-intercept of a function?We solve the equation when y=0. Let's try this from the simplified equation we got ([tex]y = 4x + 2[/tex])
[tex]0 = 4x + 2\\-2 = 4x\\\frac{-2}{4} = x\\x = - \frac{1}{2}[/tex]
We must remind ourselves that all y-intercepts have an x that is equal to 0 and that all x-intercepts have a y equal to 0.
That means that our x-intercept will be ([tex]- \frac{1}{2}, 0[/tex]) and our y-intercept will be ([tex]0, 2[/tex])
This corresponds to the 3rd option counting from the left.

When computing the control limits for the p-chart, what value is used when the population proportion of defective items is not known
Answer:
sample proportion of defective items
Step-by-step explanation:
The p-chart is a type of chart in which the sample is taken periodically from the production process, so as to determine if the population proportion of defective items in the sample falls within the control limits on the chart.
For a P-chart, as the sample size gets larger it turns more into a normal distribution making it possible to approximate the distribution of the proportion defective.

A pet store has three fish tanks, each holding a different volume of water and a different number of fish. Tank A has 5 fishes with a volume of 40 liters. Tank B has 12 fishes with a volume of 100 liters. Tank C has 23 fishes with a volume of 180,000 milliliters. Which tank has the greatest volume per fish?
Answer:
Tank B
Step-by-step explanation:
A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
a) Tank A has 5 fishes with a volume of 40 liters.
Volume per fish = 40 liters/5 fishes
= 8 liters/fish
b) Tank B has 12 fishes with a volume of 100 liters.
Volume per fish = 100 liters/12 fishes
= 8.33 liters/ fish
c) Tank C has 23 fishes with a volume of 180,000 milliliters.
Convert 180,000 milliliters to liters
1 milliliter = 0.001 liter
180,000 milliliters = x
x = 180,000ml × 0.001 l
x = 180 liters
Volume per fish = 180 liters/23 fishes
= 7.8260869565 volume per fish
Approximately = 7.83 liters/fish
Which tank has the greatest volume per fish?
The tank that had the greatest volume per fish is Tank B at 8.33 liters/ fish
2. Rohit has notes of denominations 1000, 500 & 20. He has 40 notes of Rs.20 and 20
notes of Rs.1000. He made a payment of Rs.29300. How many notes of Rs.500 did he have?
a) 12
b) 14
c) 18
d) 17
Answer:
17
Step-by-step explanation:
To find how many notes of Rs. 500 he has, we need to find out the total value of all the Rs. 500 notes.
Total value of Rs. 20 notes = 20 × 40
= 800
Total value of Rs. 1000 notes = 1000 × 20
= 20 000
Total value of Rs. 500 notes = 29 300 - 800 - 20 000
= 8500
No. of Rs. 500 notes = 8500 ÷ 500
= 17
Rohit has total 17 notes of Rs.500
What is Unitary method?" Unitary method is the process of finding value of one unit using which we can find the value of other units."
According to the question,
Number of Rs.20 notes = 40
Total amount of Rs.20 = 20 × 40
= Rs.800
Number of Rs.1000 notes = 20
Total amount of Rs.1000 = 20 × 1000
= Rs.20,000
Total amount of Rs.20 and Rs.1000 notes = 20,000 +800
= Rs.20,800
Made a payment of Rs.29,300
Left amount of Rs.500 notes = 29,300 -20,800
= Rs.8500
Number of Rs.500 notes = 8500 ÷ 500
= 17 notes of Rs.500
Hence, Rohit has total 17 notes of Rs.500.
