Step-by-step explanation:
A men travel 585 km on fourth day.
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
A man travelled 450 km on the first day and 565,000 m on the second day, the third day he travel double the distance you travel on the first day.
Here, On the fourth day he reached his destination which was 2500km from his starting point.
Let the distance he travel on the fourth day = x
So, We can formulate;
⇒ 450 km + 565,000 m + 2 × 450 km + x = 2500 km
⇒ 450 km + 565 km + 900 km + x = 2500 km
⇒ 1915 km + x = 2500 km
⇒ x = 2500 - 1915
⇒ x = 585 km

Jake received $300 for his birthday. He must decide how much of it to save and how much to spend. His bank has a 5% interest rate. How much more would be in his account after 5 years if he saved $300 than if he saved $250?
Answer:
Assuming no compounding, given an interest rate of 5%, after 5 years the $300 dollars become:
300*(1+5%)^5= $382.884469
By saving $250 instead,
250*(1.05)^5=319.07039
The difference is 382.8845-319.0704= 63.8141
Step-by-step explanation:
The formula is FV=PV*(1+r%)^T
Where:
FV- future value
PV- present value
r%- interest rate
T- Time (usually in years)

$56 they are 25% off wants to know what is the discount price
Answer:
$42
Step-by-step explanation:
This is an example of a percentage decrease.
To work out the percentage decrease you would first need to convert the percentage of 25% into a decimal. You can do this by dividing the percentage of 25 by 100, this gives you 0.25. This is because percentages are out of 100.
The next step is to minus 0.25 from 1, this gives you 0.75. This is because we are working out the percentage decrease.
To work out the discounted price you would multiply the amount of $56 by 0.75, this gives you $42.
1) Divide 25 by 100.
[tex]25/100=0.25[/tex]
2) Minus 0.25 from 1.
[tex]1-0.25=0.75[/tex]
3) Multiply $56 by 0.75.
[tex]56*0.75=42[/tex]
Max and Leah each have a lemonade stand . Max sold 12 glasses the first hour and 10 glasses each hour after that . Leah sold 8 glasses the first hour and 10 glasses each hour after that . How many glasses will each person have sold after 5 hours?
Answer:
max wil sell 52 because the first hour he sold 12 5hours -1 hour = 4 hour
4 hour × 10 p/h= 40
max sold 12+40 =52
leah will sell 58 because the first hour she sold 8
5hours - 1hour = 4 hours
4hours× 10 glasses p/h = 40
leah sold 40+8 =48 glasses
If Max and Leach sold 10 glasses each hour then after Max sold 52 glasses after 5 hours and Leach sold 48 glasses after 5 hours because it forms arithmetic progression.
What is an arithmetic progression?It is a type of sequence in which each number have a common difference from the other number. The nth term of an arithmetic progression can be calculated as a+(n-1)d.
How to calculate nth term of an A.P.?For Max we have been given that the first term is 12 and the common difference is 10.
After 10 hours the glasses which Max will sell as 12+(5-1)*10
=12+40=52 glasses
For Leach we have been given that the first term is 8 and the common difference is 10.
After 5 hours the glasses which Leach will sell as 8+(5-1)*10
=48 glasses.
Hence the number of glasses will be 52 and 48 glasses for Max and Leach.

In a large population, 69% of the people have been vaccinated. If 4 people are randomly selected, what is the probability that At least one of them has been vaccinated?
Answer:
0.991
Step-by-step explanation:
Let Q be probability none of the 4 are vaccinated.
Let P be probability that at least 1 is vaccinated.
P = 1 - Q
Now if 69% are vaccinated, then 31% are not vaccinated.
Thus any given person has a probability of 0.31 of not being vaccinated.
Q = (0.31)^4 = 0.00924
P = 1 - 0.00924 = 0.991

5. Garrett and Jeffrey are planning a treasure hunt. They decide to place a treasure at a point that is a
distance of 5 units from the x-axis and 3 units from the y-axis. Jeffrey places a treasure at point J, and
Garrett places one at point G. Who put the treasure in the right place? Explain how you know.
Answer:
Garret placed the treasure at the right place.
Step-by-step explanation:
The Cartesian plane can be used to locate the position of any given point with a coordinate. It consists of two numbered lines perpendicular to each other and intersecting at point zero of the lines.
From the statements given, 5 units from x-axis is not the same as 5 units on x-axis. Also, 3 units from y-axis is not the same as 3 units on y-axis.
So, distance 5 units from x-axis implies that a point 5 units after the x-axis. And also, distance 3 units from y-axis means 3 units after the y-axis.
With these conditions of the coordinate of the treasure, Garrett placed the treasure at the right place.

For the given data, (a) find the test statistic, (b) find the standardized test statistic, (c) decide whether the standardized test statistic is in the rejection region, and (d) decide whether you should reject or fail to reject the null hypothesis. The samples are random and independent.
Claim: μ1 < μ2, α = 0.01. Sample statistics: x^-1 = 1240, n1 = 40, x^-2 = 1200 and n2 = 80. Population statistics: σ1 = 65 and σ2 = 110.
(a) The test statistic for μ1 - μ2 is _________.
(b) The standardized test statistic for μ1 - μ2 is __________. (Round to two decimal places as needed.)
(c) Is the standardized test statistic in the rejection region?
O Yes Ο Nο
(d) Should you reject or fail to reject the null hypothesis?
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
The test statistic for μ1 - μ2 is [tex]\= x_1 - \= x_2 = 40[/tex]
b
The standardized test statistic for μ1 - μ2 is [tex]z = 2.5[/tex]

Fail to reject null hypothesis [tex]H_O : \mu_1 \ge \mu_2 ; H_a : \mu_1 < \mu_2[/tex] At the 1% significance level , there is insufficient evidence to support the claim
Step-by-step explanation:
From the question we are told that
The given data is
[tex]\= x_1 = 1240[/tex]
[tex]\= x_2 = 1200[/tex]
[tex]n_1 = 40[/tex]
[tex]\alpha = 0.01.[/tex]
[tex]n_2 = 80.[/tex]
[tex]\sigma 1 = 65 \ and\ \sigma2 = 110.[/tex]
Now the test statistic is mathematically evaluated as
[tex]\= x_1 - \= x_2 = 1240 -1200[/tex]
[tex]\= x_1 - \= x_2 = 40[/tex]
The standardized test statistic is mathematically represented as
[tex]z = \frac{\= x_1 - \= x_2}{\sqrt{\frac{\sigma_1^2}{n_1} } + \frac{\sigma_2^2}{n_2} }[/tex]
substituting values
[tex]z = \frac{\= 1240 - \= 1200}{\sqrt{\frac{65^2}{40} } + \frac{110^2}{80} }[/tex]
[tex]z = 2.5[/tex]
Now the standardized test statistic is not in the rejection region because the z value of [tex]\alpha[/tex] is 2.33 and the standardized test statistic is greater than that hence it is not in the rejection region
This implies that the test statisties failed to reject the null hypothesis at significance level of 0.01 , there insufficient evidence to support the claim

Unknown cultural affiliations and loss of identity at high elevations." These are words used to propose the hypothesis that archaeological sites tend to lose their identity as altitude extremes are reached. This idea is based on the notion that prehistoric people tended not to take trade wares to temporary settings and/or isolated areas. As elevation zones of prehistoric people (in what is now the state of New Mexico) increased, there seemed to be a loss of artifact identification. Consider the following information.Elevation Zone Number of Artifacts Number Unidentified7000-7500 ft 114 715000-5500 ft 142 23Let p1 be the population proportion of unidentified archaeological artifacts at the elevation zone 7000-7500 feet in the given archaeological area.

Step-by-step explanation:
A 100 gallon tank initially contains 100 gallons of sugar water at a concentration of 0.25 pounds of sugar per gallon suppose that sugar is added to the tank at a rate of p pounds per minute that sugar water is removed at a rate of 1 gallon per minute and that water in the tank is kept well mixed. What value of P should we pick so that that when 5 gallons of sugar solution is left in the tank the concentration is .5lbs of sugar/gallon?
At the start, the tank contains
(0.25 lb/gal) * (100 gal) = 25 lb
of sugar. Let [tex]S(t)[/tex] be the amount of sugar in the tank at time [tex]t[/tex]. Then [tex]S(0)=25[/tex].
Sugar is added to the tank at a rate of P lb/min, and removed at a rate of
[tex]\left(1\frac{\rm gal}{\rm min}\right)\left(\dfrac{S(t)}{100}\dfrac{\rm lb}{\rm gal}\right)=\dfrac{S(t)}{100}\dfrac{\rm lb}{\rm min}[/tex]
and so the amount of sugar in the tank changes at a net rate according to the separable differential equation,
[tex]\dfrac{\mathrm dS}{\mathrm dt}=P-\dfrac S{100}[/tex]
Separate variables, integrate, and solve for S.
[tex]\dfrac{\mathrm dS}{P-\frac S{100}}=\mathrm dt[/tex]
[tex]\displaystyle\int\dfrac{\mathrm dS}{P-\frac S{100}}=\int\mathrm dt[/tex]
[tex]-100\ln\left|P-\dfrac S{100}\right|=t+C[/tex]
[tex]\ln\left|P-\dfrac S{100}\right|=-100t-100C=C-100t[/tex]
[tex]P-\dfrac S{100}=e^{C-100t}=e^Ce^{-100t}=Ce^{-100t}[/tex]
[tex]\dfrac S{100}=P-Ce^{-100t}[/tex]
[tex]S(t)=100P-100Ce^{-100t}=100P-Ce^{-100t}[/tex]
Use the initial value to solve for C :
[tex]S(0)=25\implies 25=100P-C\implies C=100P-25[/tex]
[tex]\implies S(t)=100P-(100P-25)e^{-100t}[/tex]
The solution is being drained at a constant rate of 1 gal/min; there will be 5 gal of solution remaining after time
[tex]1000\,\mathrm{gal}+\left(-1\dfrac{\rm gal}{\rm min}\right)t=5\,\mathrm{gal}\implies t=995\,\mathrm{min}[/tex]
has passed. At this time, we want the tank to contain
(0.5 lb/gal) * (5 gal) = 2.5 lb
of sugar, so we pick P such that
[tex]S(995)=100P-(100P-25)e^{-99,500}=2.5\implies\boxed{P\approx0.025}[/tex]

Answer:
Step-by-step explanation:
1) Your calculator can evaluate f(-5) for you. It will be ...
f(-5) = (1/3)^(-5) -3 = 243 -3
f(-5) = 240
So, a point on the graph is (-5, 240).
Other points on the graph will be (1, -8/3), (0, -2), (-1, 0), (-2, 6).
__
2) The given function f(x) can be written as ...
f(x) = (1/3)^x -3 = (3^-1)^x -3 = 3^-x -3
So, the transformed function is transformed by adding 1, changing the horizontal asymptote from -3 to -2. The whole graph is translated upward one unit. Each of the above-listed points will have 1 added to its y-value.
