Answers
Answer:
john has a 6 out of 10 chance of picking a pencil
Answer:
P=37.5%
Step-by-step explanation:
Frequentist Probability
The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.
The equation to calculate the probability is:
[tex]\displaystyle P=\frac{f}{n}[/tex]
Where f is the number of favorable cases and n is the total cases.
John has in a cup of his desk:
6 pencils
3 blue+5 black+2 red pens=10 pens
Picking one of the utensils from the cup can be done in 16 different ways. That is the total number of cases n=16
The outcome of taking a pencil can be done in 6 ways. That is the number of favorable cases. f=6.
The probability is:
[tex]\displaystyle P=\frac{6}{16}[/tex]
Simplifying:
[tex]\displaystyle P=\frac{3}{8}[/tex]
Or expressed as a percentage:
P=3/8*100%
P=37.5%
Subtract.
1 2/5−(−3/5)

Answers
Answer: [tex][5, \infty)[/tex]
On a keyboard, you would write [5, infinity)
The square bracket means "include this value" and a curved parenthesis means "exclude this value". We cannot include infinity as it is not a number, so we always use parenthesis with either infinity.
[tex]y \ge 5[/tex] is the same as [tex]5 \le y[/tex] which is also the same as [tex]5 \le y < \infty[/tex] which may help lead to set up the interval notation answer.

Answer:
the values of angle;
a=61
b=61
c=29
Answer: All of the angles combined are 180 degrees. Since b and its adjacent angle is 90 degrees, you would subtract 90-29, which gives you 61. b=61. You would then use both angle measures to determine the other two. You would need to find two values that add up to 90 degrees for c and a. Angle b+c would be equal to 90 degrees, and angle a and d (I used d to represent the 29 degree angle) would be equal to 90 degrees, equaling a total of 180 degrees. Angle a would be equal to 61, and angle c would be equal to 29. Hope this helps.

You want to go to the movies with your friends and your parents offer to pay for everyone.
If each movie ticket is $13.50 and you plan on splitting a giant popcorn and drink that cost
$19.95 total, what is the maximum number of tickets you can buy if your parents give you
$75?
Answers
Answer:
4 tickets
Step-by-step explanation:
1. make an equation representing the situation. x is the number of how many tickets you buy
13.5x + 19.95 = 75
2. subtract 19.95 from both sides
13.5x = 55.05
3. divide by 13.5 on both sides
x = 4.08
now, you can't buy 0.08 of a ticket, so you have to round to the nearest whole number, which in this case is 4.
Answer:
4 tickets
Step-by-step explanation:.
13.5x + 19.95 = 75
13.5x = 55.05
x = 4.08
Now, you have to round to the nearest whole number, which in this case is 4.

Answers
Answer:
a
[tex]A_w = 1.667 \ hour [/tex]
b
[tex]b = 0.667 \ hour [/tex]
Step-by-step explanation:
From the question we are told that
The mean number of ticket per hour is [tex]\mu = 12 \ tickets[/tex]
The mean number of customers arrive to purchase tickets each hour is [tex]\lambda = 8 \ customers[/tex]
Generally the average time the ticket buyer must wait is mathematically represented as
[tex]A_w = \frac{\lambda }{ \mu [\mu -\lambda]}[/tex]
=> [tex]A_w = \frac{8 }{ 12 [12-8]}[/tex]
=> [tex]A_w = 1.667 \ hour [/tex]
Generally the portion of time is the ticket seller busy is mathematically represented as
[tex]b = \frac{\lambda}{ \mu}[/tex]
=> [tex]b = \frac{8}{ 12} [/tex]
=> [tex]b = 0.667 \ hour [/tex]

Cash versus accrual accounting
Newman Consulting Company maintains its records on a cash basis. During 2011 the following cash flows were recorded: cash received from customers, $420,000; and cash paid for salaries, utilities, and advertising, $240,000, $35,000, and $12,000, respectively. You also determine that customers owed the company $52,000 and $60,000 at the beginning and end of the year, respectively, and that the company owed the utility company $6,000 and $4,000 at the beginning and end of the year, respectively. Determine accrual net income for the year.
Answers
Answer:
$143,000
Step-by-step explanation:
Newman consulting company maintains its record on its cash basis
The first step is to calculate the revenue
$420,000+($60,000-$52,000)
= $420,000+$8,000
= $428,000
The expenses can be can be calculated as follows
Utilities expenses = $35,000-($6,000-$4,000)
= $35,000-$2,000
= $33,000
Advertising expenses= $12,000
Salaries expenses= $240,000
Total expenses= $240,000+$12,000+$33,000
= $285,000
Therefore the accural net income for the year can be calculated as follows
= revenue - expenses
= $428,000-$285,000
= $143,000
Hence the accrual net income for the year is $143,000

There are 40 students in a class. The teacher gave each female student 5
counters and each male student 3 counters. After the distribution of the
counters, the teacher realized that the female students had 128 more counters
than the male students,
Answers
Thus the required number of male and female students are 9 and 31 respectively.
Mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
here,
Let the number of male students is x and the number of female students be y,
According to the question,
x + y = 40
x = 40 - y ----- (1)
Now,
again from the question,
5y = 3x + 128
3x = 5y - 128
from equation 1
3 (40 - y) = 5y -128
120 - 3y = 5y - 128
120 + 128 = 8y
8y = 248
y = 31
Now,
From equation 1
x = 40 - y
x = 40 - 31
x = 9
Thus the required number of male and female students are 9 and 31 respectively.

What are arithmetic operations?The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.
They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.
As per the information given in the question,
The total length of Tape = 5 m
Total number of pieces = 6
Length of each piece = 4/5 m
Then, the total length of the pieces will be,
6 × 4/5
= 24/5
Then, the amount of tape left in the roll will be,
