How many pages should the manufacturer advertise for each cartridge if it wants to be correct 99% of the time
The manufacturer should advertise 13811 pages for each cartridge if it wants to be correct 99% of the time
z-score is the number of standard deviations from the mean value of the reference population
99%=0.99
The z-value associate with 0.99 is 2.33:
2.33 = (X - 12425) / 595:
X - 12425 = 2.33 * 595
X = (2.33 * 595) + 12425
X = 138111
Therefore, The manufacturer should advertise 13811 pages for each cartridge if it wants to be correct 99% of the time

A boy had a packet of 320 candies with 2 different flavours. 7/16 were orange flavour and the rest were lemon. He gave his friend 30 orange candies and some lemon ones. As a result, the ratio of the number of orange candies to that of lemon became 11:15. How many lemon candies did he give his friend
30 lemon candies he give his friend.
It is given that a boy had 320 candies. There were 2 flavors. 7/16 were orange flavor and the rest were lemon. He gave his friend 30 orange candies and some lemon ones.
320 (7/16) = 140 were orange
320 - 140 = 180 were lemon
Let x be the number of lemon ones he gave away
So,
[ 140 - 30 ] / [ 180 - x ] = 11/15
110 = (11/15) ( 180 - x )
(15/11) (110) = 180 - x
150 = 180 - x

Nathan received $1,500 dollars for his birthday. He saves 3/5 of his money. 6/20 of his money was used to buy a new game. How much money does he have left?
Answer:
$150
Step-by-step explanation:
→ Find 3/5 of 1500
( 1500 ÷ 5 ) × 3 = 900
→ Find 6/20 of 1500
( 1500 ÷ 20 ) × 6 = 450
→ Find the sum of the 2 numbers
900 + 450 = 1350
→ Minus it from the original 1500
1500 - 1350 = $150
Which linear function has the same y-intercept as the one that is represented by the graph? On a coordinate plane, a line goes through points (negative 4, 0) and (0, 3). a y = 2 x minus 4 b y = 2 x minus 3 c y = 2 x + 3 d y = 2 x + 4
The line which is having same y intercept as the line which passes through points (-4,0) and (0,3) is y=2x+3.
Given Points through which the line passes through are (-4,0) and (0,3)
We have to find the equation whose y intercept is equal to the y intercept of the line whose points given above.
First of all we have to find the y intercept of the line which passes through (-4,0) and (0,3). Equation of line is :
y-y1=(y2-y1)/(x2-x1)*(x-x1)
y-0=(3-0)/(0+4) *(x+4)
y=3/4(x+4)
y -intercept exists where x=0
put x=0
y=3
So the options are:
y=2x-4y=2x-3y=2x+3y=2x+4By putting the value of x in all options we will find
y=-4
y=-3
y=3
y=4
So the third option is correct.
Hence the line whose y-intercept matched with the given line is y=2x+3.

The average monthly temperature T(m), in degrees Celsius, in a particular city varies according to the model T of m equals 4 times sine of the quantity pi over 6 times m end quantity plus 2 comma where m represents the months of the year and January begins at m = 0. Between what months will the temperature be below 0°C?
The months with temperature below 0° is August and October.
GIven,
T(m) = 4 sin (π/6 m)₊2
In the above equation, T(m) is the average temperature in a month in degrees Fahrenheit, and m is the month of the year.
T(8) = 4 sin (8π/6 m)₊2
= 4 sin (4π/3 )₊2
= 4 sin (π₊π/3 )₊2
= ₋4 sin π/3 ₊2
= ₋4×√3/2 ₊2
= ₋2√3 ₊ 2 <0
The function for the average monthly temperature, in m months from january is given by
T(0) = 4 sin(10π/6) ₊ 2
= 4 sin(5π/3) ₊ 2
= 4 sin(2π ₋ π/3) ₊ 2
= - 4sin π/3 ₊ 2 = ₋4 × √3/2 ₊ 2
= ₋2√3 ₊2<0
we can notice that after january, from august till october the months will face temperature below 0 degrees.
So the answer is August and October.

After four years of higher education, Julia just graduated with a Bachelor's degree in Engineering from USC where the annual cost of tuition was $22,000. She paid for college by earning $11,000 annually through the work study program and receiving an annual scholarship. She covered the remainder of the costs by taking out $12,000 in student loans. If she didn't fund her education with savings or grant money, what was the amount of Julia's annual academic scholarship?
Answer:
$32,000
Step-by-step explanation:
overall cost for 4 years was $88,000. She made $44,000 after 4 years. After all 4 years she had to take out $12,000 to pay. 88,000-44,000=44,000 44,000-12,000=32,000
Answer:
$8,000
Step-by-step explanation:
Tuition per year: $22,000
Work Study Earnings per year: $11,000
Student Loans per year: $12,000 / 4 = $3,000
Annual Academic Scholarship per year: $x
Per Year Calculations
$22,000 = $11,000 + $3,000 + $x
$x = $22,000 - $11,000 - $3,000
$x = $8,000

What does it mean for an event to be unusual? why should the cutoff for identifying unusual events not always be 0. 05?.
An unusual event is an occurrence that has a low probability of happening. The cutoff for identifying unusual events not always be 0.05, because it is not always a good idea to utilize the same cutoff to spot unexpected occurrences.
What is an unusual event?An unusual event is an occurrence that has a low probability of happening.
If an event is improbable, its likelihood is zero. If an occurrence is unavoidable, its probability is one.
The probability of an event happening increases as it gets closer to 1. An occurrence that has a probability of 0.375, for instance, is more likely to happen than one with a probability of 0.125.
The less likely an event is to occur, the closer the probability is to 0. An unusual event is what this kind of event falls under. A probability of 5%, or 0.05, is typically regarded as unusual event.

After drinking of 61 cups of tea, the Joneses found that they were out of sugar. The Connors' sugar box was enough to last them thought 88 cups of tea. Both families put either 2 or 3 pieces of sugar per cup. How many sugar cubes were in the box
The number of sugar cubes in the box is 180
How to determine the number of sugar cubes?The given parameters are:
Layers = 5Pieces = 2 or 3Cups of tea = 61 and 88Multiply 61 and 88 by 2 and 3
61 * 2 = 122
61 * 3 = 183
88 * 2 = 176
88 * 3 = 264
The number of sugar cubes cannot be 122 and 264, because they are out of the range
So, we have:
183 and 176
There are 5 layers.
This means that the number of sugar cubes is divisible by 5.
The only number between 176 and 183 that is divisible by 5 is 180
Hence, the number of sugar cubes is 180
