how do you divide fractions
Dividing fractions is basically the same thing as multiplying fractions but by the reciprocal.
For example, [tex]\frac{3}{8}[/tex] ÷ [tex]\frac{1}{4}[/tex] you would change this so in the second fraction that is being divided, the numerator and the denominator would switch places. Instead, it would be...
[tex]\frac{3}{8}[/tex] x [tex]\frac{4}{1}[/tex]

Step-by-step explanation:
A long distance phone company charges $1.01 for the first 25 minutes of a call, then $0.09 for each additional minute. A call cost $9.56 how long did it last?
Final answer:
Subtracting the initial charge from the total cost and then dividing the remainder by the cost per additional minute, we find that the call lasted for 120 minutes.
Explanation:
The student is asking how long a phone call lasted based on the cost of the call with a given rate structure. We know that the first 25 minutes cost $1.01 and each additional minute costs $0.09. The total cost of the call was $9.56. To determine the duration of the call, we need to calculate the cost of the additional minutes beyond the first 25, and then find out how many of those minutes were used.
Subtract the initial charge from the total cost: $9.56 - $1.01 = $8.55.
Divide the remaining cost by the cost per additional minute: $8.55 / $0.09 = 95 minutes.
Add the initial 25 minutes to the additional minutes: 25 + 95 = 120 minutes.
Therefore, the call lasted for 120 minutes.

Assume that we want to find the probability that when five consumers are randomly selected, exactly two of them are comfortable with delivery by drones. Also assume that 38% of consumers are comfortable with the drones (based on a survey). Identify the values of n, x, p, and q. The value of n is __. (Type an integer or a decimal. Do not round.) The value of x is __. (Type an integer or a decimal. Do not round.) The value of p is __. (Type an integer or a decimal. Do not round.) The value of q is ___ . (Type an integer or a decimal. Do not round.)
In the given problem, n (the number of trials) is 5, x (the amount of 'successes' we're seeking) is 2, p (the probability of success) is 0.38, and q (the probability of failure) is 0.62.
Explanation:In the given problem, we are conducting a binomial experiment where five consumers are randomly selected and we are interested in the number who are comfortable with drone delivery. So, the total number of trials, n, will be equal to the number of consumers selected, which is 5.
The value to be observed, x, is exactly 2, because we want to find out the probability of exactly two of them are comfortable with delivery by drones.
The probability of success, p, is the proportion of consumers that are comfortable with delivery by drones, so p = 0.38 (or 38%).
The probability of failure, q, is the proportion of consumers that are not comfortable with delivery by drones, so q = 1 - p = 1 - 0.38 = 0.62.

What is the value of the function at x=−3?
y=−3
y = 0
y = 4
y = 3
Answer:
the value of the function at x=-3 is y=4
Step-by-step explanation:
We are given with the graph of the function
In the given graph the x value is the input and f(x) is the output
x is the input value and f(x) is the output value y
given the input value x=-3
To find the function value when x=-3 we need to find out y from the graph when x=-3

In the year 2016, the estimated population of Canadian geese in a city was 750. The Canadian geese population is expected to grow at a rate of 12% each year. What is the Canadian geese population in 2022? Round the answer to the nearest whole number.
Keywords:
population, Canadian geese, growth rate
For this case, we must find the population of Canadian geese for the year 2022, taking into account that in 2016 the estimated population of geese was 750 and as additional data, the population of geese has a growth rate of 12% each year.
Then, we started finding the Canadian geese population for 2017, for this we make a rule of three:
750 -----------> 100%
x --------------> 12%
DOnde "x" represents the number of geese that is added to the base population of 2016.
[tex]x = \frac {12 * 750} {100}\\x = 90[/tex]
Thus, the geese population for 2017 is: [tex]750 + 90 = 840[/tex]
We find the population of Canadian geese for the year 2018, following the previous steps since the annual growth rate is constant:
840 -----------> 100%
x --------------> 12%
where "x" represents the number of geese that is added to the base population of the year 2017.
[tex]x = \frac {12 * 840} {100}\\x = 100.8[/tex]
Thus, the geese population for 2018 is: [tex]840 + 100.8 = 940.8[/tex]
We found the population of Canadian geese for the year 2019, following the previous steps since the annual growth rate is constant:
940.8 -----------> 100%
x --------------> 12%
Where "x" represents the number of geese that is added to the base population of the year 2018.
[tex]x = \frac {12 * 940.8} {100}\\x = 112.896[/tex]
Thus, the geese population for 2019 is: [tex]940.8 + 112.896 = 1053.696[/tex]
We find the population of Canadian geese for the year 2020, following the previous steps since the annual growth rate is constant:
1053.696 -----------> 100%
x --------------> 12%
Where "x" represents the number of geese that adds to the base population of the year 2019.
[tex]x = \frac {12 * 1053.696} {100}\\x = 126.44[/tex]
Thus, the geese population for 2020 is: [tex]1053.696 + 126.44 = 1180.12[/tex]
We found the population of Canadian geese for the year 2021, following the previous steps since the annual growth rate is constant:
1180.12 -----------> 100%
x --------------> 12%
Where "x" represents the number of geese that is added to the base population of the year 2020.
[tex]x = \frac {12 * 1180.12} {100}\\x = 141.6[/tex]
Thus, the population of geese for 2021 is:[tex]1180.12 + 141.6 = 1321.7[/tex]
We found the population of Canadian geese for the year 2022, following the previous steps since the annual growth rate is constant:
1321.7 -----------> 100%
x --------------> 12%
[tex]x = \frac {12 * 1321.7} {100}\\x = 158.6[/tex]
Where "x" represents the number of geese that adds to the base population of the year 2021.
Thus, the population of geese for 2022 is: [tex]1321.7 + 158.6= 1480.3[/tex]
ANswer:
The population of Canadian geese by 2022 will be approximately 1480 geese
The sum of two numbers is 56. Their difference is 18.
The numbers are 37 and 19
From the question,
Let the numbers be x and y
From the first statement
The sum of two numbers is 56.
That is,
x + y = 56 --------- (1)
From the second statement
Their difference is 18
That is,
x - y = 18 ----------- (2)
Add equations (1) and (2)
x + y + x - y = 56 + 18
2x = 74
∴ x = 74 ÷ 2
x = 37
Substitute the value of x into equation (1) to determine the value of y
x + y = 56
37 + y = 56
y = 56 - 37
y = 19
∴ x = 37 and y = 19
Hence, the numbers are 37 and 19.
