Given:
Number of color pens Tracy have = 63
Number of color pens Jacob have = 46
To find:
How many more colors pens does Tracy have than Jacob?
Solution:
We need to find the difference between the number of color pens Tracy have and the number of color pens Jacob have.
[tex]Difference=63-46[/tex]
[tex]Difference=17[/tex]
Therefore, Tracy have 17 more color pens than Jacob.

A florist shop represents its first month’s sales with the equation y = 168 x + 8, where x represents the number of days that the shop is open and y represents the sales in dollars. The owner of the shop would like to calculate the number of days it took to reach $3,200 in sales. Which would be used to solve the problem?
Substitute 3,200 for x.
Add 8 and 3,200.
Divide 3,192 by 168.
Isolate y in the equation.
Answer:
Divide 3,192 by 168.
Step-by-step explanation:
Given
[tex]y = 168x + 8[/tex]
[tex]y = 3200[/tex]
Required
Step to required to get x when [tex]y = 3200[/tex]
The first step is to substitute [tex]3200[/tex] for [tex]y[/tex]
[tex]3200 = 168 * x + 8[/tex]
Subtract both sides by 8
[tex]3192 = 168 * x[/tex]
Divide both sides 168 ---- [this answers the question]
[tex]19 = x[/tex]
[tex]x = 19[/tex]
Answer:
Divide 3,192 by 168.
Step-by-step explanation:
Divide 3,192 by 168.
Step-by-step explanation:
Given
Required
Step to required to get x when
The first step is to substitute for
Subtract both sides by 8
Divide both sides 168 ---- [this answers the question]
A jug is 80% full of water. After 360 millimeters of water are poured out, the jug is 60% filled with water. What is the capacity of the jug?
15 POINTS!!
Answer:
1800ml
Step-by-step explanation:
Given data
let the capacity of the Jug be x millimeters
from 80% to 60% = 20%
Since 20% of the capacity is equivalent to 360ml
the 100% will be x ml
cross multiply we have
360*100= 20*x
x= 36000/20
x= 1800ml
Hence the capacity of the jug is 1800ml

Determine the value of y.
1)
46°
2)
226°
3)
132°
4)
452°
Answer:
y = 46
Step-by-step explanation:
Angle Formed by Two Tangents= 1/2(difference of Intercepted Arcs)
We can find the other arc by the total arc of a circle minus the arc length 226
y = 1/2 ( 226 - ( 360 -226))
y = 1/2 ( 226 -134)
y = 1/2 (92)
y = 46
Which is the graph of f(x) =3 sqrtx/4?
Step-by-step explanation:
f(x) = 3√x /4
x=0 => y = 0
x=1 => y = 0.75
x=4 => y = 1.5 ==> (4, 1.5)
x=16=>y= 3
the right answer is the second graph
There are 24 chairs in a room numbered 1 through 24. If nine girls and 15 boys sit on these chairs at random, what is the probability that the thirteenth chair is occupied by a boy?
Answer:
[tex]5/8[/tex]
Step-by-step explanation:
Since all the people sit on the chairs at random, the probability of a certain chair being occupied by a boy is equal to the probability of randomly picking a boy from the class. Since there are 24 people total and 15 of them are boys, there is a [tex]\frac{15}{24}=\boxed{\frac{5}{8}}[/tex] chance that the thirteenth chair is occupied by a boy.

y = 5/2x-10;(-6,-29)
Answer:
[tex]y=\frac{5}{2}x-14[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)Parallel lines always have the same slope1) Determine the slope (m)
[tex]y=\frac{5}{2}x-10[/tex]
In the given equation, [tex]\frac{5}{2}[/tex] is in the place of m, making it the slope. Because parallel lines have the same slope, the line we're currently solving for therefore has a slope of [tex]\frac{5}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{5}{2}x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=\frac{5}{2}x+b[/tex]
Plug in the given point (-6,-29) and solve for b
[tex]-29=\frac{5}{2}(-6)+b[/tex]
Simplify -6 and 2
[tex]-29=\frac{5}{1}(-3)+b\\-29=(5)}(-3)+b\\-29=-15+b[/tex]
Add 15 to both sides to isolate b
[tex]-29+15=-15+b+15\\-14=b[/tex]
Therefore, the y-intercept is -14. Plug this back into [tex]y=\frac{5}{2}x+b[/tex]:
[tex]y=\frac{5}{2}x-14[/tex]

As a manager of a company you are given 2 estimates for the annual firm’s profits: 1) Estimate A predicting that the mean profit would be between $1mil and $1.5 mil which is a 95% confidence interval; 2) Estimate B that the annual profits are between $1.2 mil and $1.4 mil, a 93% confidence interval. Which of the two estimates is more accurate and why?
Answer and Explanation:
A confidence interval determines the probability that a range of values(e.g-given a large data set )has the true parameter. Example, to find mean of height of 30+ men, our confidence interval will say that there is 96% confidence that the mean height of 30+ men is between 5ft and 6ft. While confidence intervals, narrow or broad with high or low significance levels may not be akin to accuracy, it will only help to determine the precision or otherwise of our estimate. For example, if confidence interval is narrow as in second option and confidence level is lower, it only narrows down our options to ascertain the true mean or parameter we are investigating and doesn't exactly affect accuracy since we are still not 100% confident our true mean lies in this interval.

Jeans are on sale for 20% off the regular price. Which function would give you the total cost for purchasing a pair of jeans that costs x dollars?
Answer:
0.8X = Final cost
Step-by-step explanation:
Given that jeans are on sale for 20% off the regular price, to determine which function would give you the total cost for purchasing a pair of jeans that costs X dollars, the following calculation must be performed:
1X = Initial cost of the jeans
20% = 0.2
1 - 0.2 = 0.8
0.8X = Final cost
evaluate g(x)=x/x-3, if g(1/2)
Answer:
-1/5
Step-by-step explanation:
g(x) = x/(x-3)
Substituting x = 1/2 in g(x),
g(1/2) = 1/2/(1/2-3)
= 1/2/(1/2-6/2)
= 1/2/(-5/2)
= 1/2 ÷ - 5/2
= 1/2 x -2/5
= - 1/5

Suppose 2500 dollars is invested at 4% for 5 years. Find the account balance if it is
compounded daily, monthly, quarterly?
answer step by step
Answer:
Kindly check explanation
Step-by-step explanation:
Using the compound interest formula :
A = P(1 + r/n)^nt
A = final amount ; r = rate ; n = number of compounding times per period ; t = period ; P = principal
P = 2500 ; r = 4% = 0.04 ; t = 5 years
Daily compounding, n = 365
Yearly compounding, n = 1
Quarterly compounding, n = 4
Daily compounding :
A = 2500(1 + 0.04/365)^(5*365)
A = 2500(1.0001095)^1825
A = $3053.4734
Yearly :
A = 2500(1 + 0.04/1)^(5*1)
A = 2500(1.04)^5
A = $3041.6323
Quarterly:
A = 2500(1 + 0.04/4)^(5*4)
A = 2500(1.01)^20
A = $3050.4751
the population of a town increases at a rate proportional to its population with an initial population of 1000. The corect initial value problem for the population p(t) as a function of time is
Answer:
This means that the correct initial value problem for the population p(t) as a function of time is is [tex]P(0) = 1000[/tex]
Step-by-step explanation:
The population of a town increases at a rate proportional to its population:
This means that this situation is modeled by the following differential equation:
[tex]\frac{dP}{dt} = kP[/tex]
In which k is the growth rate.
By separation of variables, the solution is given by:
[tex]P(t) = P(0)e^{kt}[/tex]
In which P(0) is the initial population.
Initial population of 1000.
This means that the correct initial value problem for the population p(t) as a function of time is is [tex]P(0) = 1000[/tex]
