Answer:
the answer is to make the first offer!
Step-by-step explanation:
Since the surplus ($100000) is rapidly depleting, and though the second individual collects the whole surplus, it is already less than half of the surplus from the previous day. So, once you make the first bid, any offer above 100,000 would be fair to the second person and if he rejects the offer, he will only be able to get 100,000 the next day. You will raise the payout by 100000(1 ) this way.
Mike wants to find the confidence interval for a set of data. He knows the sample size and the sample proportion. Which other piece of information does he need to determine the confidence interval?
A.
the critical value
B.
the number of favorable responses
C.
the standard error of the mean
D.
the standard deviation
Answer:
A
Step-by-step explanation:
The other piece of information Mike needs to determine the confidence interval is the critical value.
What is a confidence interval?A confidence interval is a range of estimates for a variable that is uncertain. A confidence interval is calculated at a specified confidence level; the 95% confidence level is the most frequent, although other values, such as 90%or 99%, are also used.
To determine the confidence interval for a set of data sample size, the sample proportion, and the critical value are needed to be known.
Hence, the other piece of information Mike needs to determine the confidence interval is the critical value.

via Edge
Answer:
By showing an example of ditributive property against addition.
Step-by-step explanation:
Let's say:
x = 5
y = 10
sin = 4
let's plug it in:
sin(x + y)
4(5 + 10) Let's solve:
20 + 40 = 60
Let's see if we get the same result:
5 + 10 = 15.

There are only seven days left until we launch of our new product and we only have $668 left in our promotion budget we need to spend $85 on the last day can you please calculate how many dollars a day we can spin on the remaining days
Answer:
$97.17
Step-by-step explanation:
First, subtract 85 from 668:
668 - 85
= 583
This means that our budget for all of the days excluding the last day is $583
To find how much can be spent on the remaining days, divide 583 by 6:
583/6
= 97.17
So, approximately $97.17 can be spent on the remaining days

Step-by-step explanation:
This is actually pretty simple
The distance the tip travels is the arc length and the length of the pendulum is the radius of a circle
The formula for arc length is Angle in Radians x Radius
So pi/12 * 4 = pi/3 m
We know this is how much it travels every second so it is going at pi/3 m/s
One minute is 60 seconds
pi/3 * 60 = 20pi m

A pharmaceutical company is conducting a study on whether or not their new vaccine is effective in preventing chicken pox. The researchers rejected the null hypothesis and stated that the vaccine was effective. However, subsequent studies found out that the vaccine did not have any effect on combating chicken pox. What type of error did the researchers make
Answer:
The answer is "Type 1 error".
Step-by-step explanation:
The error of type I, frequently known as a 'false positive': its error in judgment that perhaps a null hypothesis is simply rejected. This is the mistake of accepting a possible (actual interest hypothesis) hypothesis whenever the results could be attributed to chance since the researchers deny, if valid, the null hypothesis.

Answer:
a) radius: 6 (m); mass: 22 (kg)
b) volume: 19 (m³)
c) d ≈ 2.8×10^3 kg/m³
Step-by-step explanation:
The order of magnitude is the exponent of 10 when the number is written in scientific notation.
a) radius: 1.6×10^6 m, so the order of magnitude is 6 when the units are meters.
mass: 4.8×10^22 kg, so the order of magnitude is 22 when the units are kg.
__
b) The volume is ...
V = (4/3)πr^3 ≈ 1.716×10^19 m^3, so the order of magnitude of the volume is 19 when the units are m^3.
__
c) The ratio of mass to volume is ...
d = (4.8×10^22)/(1.716×10^19) ≈ 2.8×10^(22-19) = 2.8×10^3 kg/m^3, so the order of magnitude is 3 when the units are kg/m^3.

A consulting firm claimed that 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex. The claim was tested by taking a random sample of 60 online shoppers and assigning them each a different randomly selected e-commerce Web site to test. 45 reported sufficient frustration with their sites to deter making a purchase. The data was entered into STATISTIX and the following output was generated:
Hypothesis Test - One Proportion
Sample Size 60
Successes 45
Proportion 0.75000
Null Hypothesis: P = 0.65
Alternative Hyp: P > 0.65
Difference 0.10000
Standard Error 0.05590
Z (uncorrected) 1.62 P 0.0522
Method 95% Confidence Interval
Simple Asymptotic (0.64043, 0.85957)
Which of the following statements is correct if we are testing at α = 0.05?
a. There is sufficient evidence to indicate that more than 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex.
b. There is sufficient evidence to indicate that exactly 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex.
c. There is insufficient evidence to indicate that exactly 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex.
d. There is insufficient evidence to indicate that more than 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex.
Answer:
b. There is sufficient evidence to indicate that exactly 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex.
Step-by-step explanation:
Not significant,accept null hypothesis that population proportion = 0.65
When we accept the null hypothesis that P= 0.65
Then only option b is correct which states that there is sufficient evidence to support that population proportion is exactly 0.65 .
1) We obtain a P - value of 0.0522 which is greater than 0.5 indicating that the null hypothesis is not rejected.
The rejection region for this right-tailed test is z > 1.64
2) Test Statistics
z= p`-p0/ sqrt(p0(1-p0)/n)
The z-statistic is computed as follows:
z= 0.75-0.65/ √(0.65*0.35)60
z= 1.624
3) Decision about the null hypothesis
Since it is observed that z = 1.624 is less than z ∝=1.64, it is then the null hypothesis is not rejected.

Mr. Farris drives 7 1/2 miles directly west of his home to a restaunt.he then drives 8 2/3 miles directly east of the restauant to his office. how far , and in what direction is his office from his home ?
Answer:
2 1/6
Step-by-step explanation:
8 2/3 - 7 1/2 = 2 1/6
9514 1404 393
Answer:
1 1/6 miles east of home
Step-by-step explanation:
If we consider east to be positive, then the distance from home to office is ...
(-7 1/2) +(+8 2/3) = -7 3/6 +8 4/6 = (8 -7) +(4/6 -3/6) = +1 1/6
Farris's office is 1 1/6 miles east of his home.
Jenny is x years old. Thomas is 3 times as old as her. Jenny is 5 years older than Alexis.
A) Find Alexis's age in terms of x
B) Find Thomas's age in terms of x.
C) If x=12, how much older is Thomas than Jenny?..
Answer:
A) Alexis is x-5 years old
B) Thomas is 3x years old
C) Thomas is 24 years older than Jenny (3×12=36 ; 36-12)
Alexis's age is x - 5.
Thomas's age is 3x.
Thomas is 24 years older than Jenny.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
A)
Jenny = x years old
Alexis = 5 years younger than Jenny.
So,
Alexis's age in terms of x.
Alexis's age
= Jenny's age - 5
= x - 5
B)
Thomas = 3 times as old as Jenny.
Thomas's age in terms of x.
Thomas's age = 3x
C)
x = 12,
Jenny = 12 years old.
Alexis = 5 years younger than Jenny,
So,
Alexis's age
= Jenny's age - 5
= 12 - 5
= 7
Now,
Thomas = 3 times as old as Jenny.
And,
Jenny = 12 years old.
Thomas's age
= 3x
= 3 x 12
= 36
Now,
Thomas's age - Jenny's age
= 36 - 12
= 24
Therefore,
Alexis's age = x - 5.
Thomas's age = 3x
Thomas is 24 years older than Jenny.
