what is 5/8 minus 3/10
Answer:
13/40
Step-by-step explanation:
5/8 - 3/10
get a common denominator of 40
5/8*5/5 - 3/10 *4/4
25/40 - 12/40
13/40
Answer:
13/40
Step-by-step explanation:
We can find the lowest common multiple of 8 and 10, so that the two fractions will have the same denominator.
The LCM of 8 and 10 is 40, so we can rewrite 5/8 as 25/40 by multiplying the numerator and denominator by 5, and rewrite 3/10 as 12/40 by multiplying the numerator and denominator by 4.
This makes the subtraction easier, as we find 25/40 - 12/40.
We get (25-12) / 40, or 13/40.

Marc mows lawns for $25 each lawn, plus $5 for every hour he spends mowing. The equation for his total earnings per lawn is y = 25 + 5h, where y represents his total earnings and h represents the number of hours he works. What does the flat pay of $25 represent in this situation? Dependent variable Independent variable Intercept Slope
Answer:
The flat pay $25 represents the interceptStep-by-step explanation:
To answer this question we need to first understand and compare it with the equation of straight line.
i.e [tex]y= mx+c[/tex] which is the equation of line
where m= slope
y= dependent variable
x= independent variable
c= intercept
Given
[tex]y= 25+5h[/tex]
comparing both expression we can see that
25 corresponds to c which is the intercept
The flat pays $25 represent the intercept.
Given that,
Marc mows lawns for $25 each lawn, plus $5 for every hour he spends mowing. The equation for his total earnings per lawn is y = 25 + 5h, where y represents his total earnings and h represents the number of hours he works.Based on the above information, the calculation is as follows:
y = mx + c
where m= slope
y= dependent variable
x= independent variable
c= intercept
And,
y = 25 + 5h
So it is an intercept

In the polynomial below, what number should replace the question mark to produce a difference of squares? X^2 + ?x -49 A. 0 B. 14 C. 49 D.7
Answer:
A
Step-by-step explanation:
The difference of squares formula is a² - b² = (a + b)(a - b). We want this polynomial to be in the form a² - b². We notice that x² and 49 are perfect squares already which means that we don't need the x term. To get rid of it, its coefficient must be 0 because 0 times anything is 0, thus the x term will be removed and we'll be left with x² - 49 which is a difference of squares.

In a class of students, the following data table summarizes the gender of the students
and whether they have an A in the class. What is the probability that a student who
has an A is a female?
Answer:
5/13
Step-by-step explanation:
number of female students who have an A: 5
total number of female students: 13
The probability that a student who has an A is a female is 3/8
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
What is chain rule in probability?For two events A and B, by chain rule, we have:
[tex]P(A \cap B) = P(B)P(A|B) = P(A)P(B|A)[/tex]
where P(A|B) is probability of occurrence of A given that B already occurred.
We're specified a frequency table as:
Female Male
Has an A 3 5
Does not have an A 8 13
We want to get P(Student is female if its given that student has an A).
Symbolically, we need P(Female | Has an A).
P(Student is female | Student has an A) = P(Student is female ∩ Student has an A) / P(Student has an A)
Now, P(Student is female ∩ Student has an A) = n(Student is female∩ Student has an A) / n(all type of students) = 3/(3+5+8+13) = 3/29
Also, P(Has an A) = n(has an A)/ n (All type of students) = n(has an A)/29
Since n(has an A) = number of students having A = females having A + males having A = 3+5 = 8
Thus, P(Has an A) = 8/29
Thus, we get:
P(Female | Has an A) = P(Female ∩ Has an A) / P(Has an A) = [tex]\dfrac{3/29}{8/29} = \dfrac{3}{8}[/tex]
Thus, the probability that a student who has an A is a female is 3/8

Two cars start out at the same point and at the same time one starts driving north while the other starts driving east at a speed that is 10 mph faster than the car driving north. 12 hours after the cars start driving they are 600 miles apart. What was the speed of each car?
Let x be the speed of the first car in miles per hour. After 12 hours it will have gone 12x miles. The other car, driving east, has speed x+ 4. After 12 hours it will have gone 12(x+ 4) miles. Again by the Pythagorean theorem,
(12x)^2+(12(x+4)^2=600^2. Solve that equation for x.
a rectangle has a width w and it's length is 3w-2. if the area is 65ft^2, find the length and width of the rectangle.
Answer:
Width = 5
Length = 13
Step-by-step explanation:
Area of a rectangle:
=> L x W = Area
After knowing this, we could find the factors of 65
=> 65 = 5 x 13, 1 x 65
So, the only way is 5 x 13.
So, Width = 5
Length = 13
Let's check whether our answer is correct.
=> (3w - 2) * w = 65
=> (3 (5) - 2) * 5 = 65
=> (15 - 2) * 5 = 65
=> 13 * 5 = 65
=> 65 = 65
So, our answer is correct.
Determine what type of model best fits the given situation: The temperature of a cup of coffee decreases by 5 F every 20 minutes.
Answer:
A first-order polynomial best fits the given situation.
Step-by-step explanation:
The statement indicates a constant rate of change in a given time interval, so the model that best fits the given situation is a first-order polynomial model, which is a generalized form of a model with direct proportionality. That is:
[tex]T = T_{o} + r \cdot t[/tex]
Where:
[tex]T[/tex] - Current temperature, measured in Fahrenheit degrees.
[tex]T_{o}[/tex] - Initial temperature, measured in Fahrenheit degrees.
[tex]r[/tex] - Temperature rate of change, measured in Fahrenheit degrees per minute.
[tex]t[/tex] - Time, measured in minutes.
The statement describes the temperature rate of change, which is equal to:
[tex]r = \frac{5\,^{\circ}F}{20\,min}[/tex]
[tex]r = \frac{1}{4}\,\frac{^{\circ}F}{min}[/tex]
2. How do you find P(A or B) if A and B are independent events for one action, such as spinning a four-color spinner once and finding P(red or blue)?
Answer:
P(red or blue) = [tex]\frac{7}{16}[/tex].
Step-by-step explanation:
We have to find P(A or B), if A and B are independent events for one action, such as spinning a four-color spinner once.
Firstly, as we know that the formula for finding P(A or B) is given by;
P(A or B) = P(A) + P(B) - P(A and B)
Since it is stated that event A and B are independent, this means that there is no dependence of any one event on another event, so;
P(A and B) = P(A) [tex]\times[/tex] P(B)
Now, we can find P(A or B) = P(A) + P(B) - P(A) [tex]\times[/tex] P(B); is we know that the probabilities of happening of both events.
Similarly, P(red or blue) = P(red) + P(blue) - P(red) [tex]\times[/tex] P(blue).
Since the event is spinning a four-color spinner once and assuming there are four different colors, so the probability of wheel stopping on each color is ([tex]\frac{1}{4}[/tex]).
So, P(red or blue) = [tex]\frac{1}{4} +\frac{1}{4} -(\frac{1}{4} \times \frac{1}{4} )[/tex]
= [tex]\frac{2}{4} -\frac{1}{16}[/tex] = [tex]\frac{7}{16}[/tex].

If a is an arbitrary nonzero constant, what happens to a/b as b approaches 0
Answer:
a/b tends to an infinite value
Step-by-step explanation:
If If a is an arbitrary nonzero constant, and we are to look for a/b as b approaches zero, we can represent this statement using limits. The statement is expressed as:
[tex]\lim_{b \to 0} \dfrac{a}{b}[/tex]
Substituting b = 0 into the function
[tex]= \dfrac{a}{0} \\\\= \infty \\\\\lim_{b \to 0} \dfrac{a}{b} = \infty\\ \\\\[/tex]
Since the limits of a tends to infinity as b tends to zero hence we can conclude that If a is an arbitrary nonzero constant then a/b tends to infinity or is undefined as b approaches 0

The table shows the estimated number of lines of code written by computer programmers per hour when x people are working. A 2-column table with 6 rows. The first column is labeled people working with entries 2, 4, 6, 8, 10, 12. The second column is labeled lines of code written hourly with entries 50, 110, 160, 210, 270, 320. Which model best represents the data?
Answer:
We make the table of these values at different values of x.
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104

8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Hence, the function that best represents the data is:
Option C.
y=26.9x-1.3
Step-by-step explanation:
Considering the situation described, it is found that a linear model best represents the data, because there is a relatively consistent additive rate of change.
When to use a linear model and when to use an exponential model?If the rate of change is additive, that is, the difference between consecutive terms is the same, a linear model is used.If the rate of change is multiplicative, that is, the quotient between consecutive terms is the same, an exponential model is used.In this problem, when the input changes by 2, the output always increases between approximately 50 and 60, that is, the same values, hence a linear model best represents the data, because there is a relatively consistent additive rate of change.
