Jane has just begun her new job as on the sales force of a very competitive company. In a sample of 16 sales calls it was found that she closed the contract for an average value of 108 dollars with a standard deviation of 12 dollars. Company policy requires that new members of the sales force must exceed an average of more than $100 per contract during the trial employment period. Can we conclude that Jane has met this requirement at the significance level of 90%
Answers
Answer:
There is significant evidence that Jane has met the requirement.
Step-by-step explanation:
Given that:
μ = 100
μ > 100
Sample size, n = 16
Sample mean, x = 108
Sample standard deviation, s = 12
Level of significance, α = 0.1
Degree of freedom, df = n - 1 = 16 - 1 = 15
Test statistic
T = (x - μ) / s÷sqrt(n)
Tstatistic = (108 - 100) / 12 ÷ sqrt(16)
Tstatistic = 8 / 3
Tstatistic = 2.6667
Using the pvalue calculator :
Tstatistic at 0.1, df = 15 ;
P-value = 0.008799
Since pvalue < α
We reject the Null
The is no significant evidence to conclude that Jane has exceeded an average of more than $100

Solve this quadratic equation by completing the square.
x^2 + 6x = 18
Answers
Step-by-step explanation:
Use formula
[tex] (\frac{b}{2} ) {}^{2} [/tex]
To add a third new term and factor to find the answer. Example
[tex]x {}^{2} + 6x = 18[/tex]
[tex]( \frac{6}{2} ) {}^{2} [/tex]
Which equal 9. so our equation look like
[tex] {x}^{2} + 6x + 9 = 18 + 9[/tex]
The only number that multiply to 9 and add up to 6 is 3. So we write our equation like this.
[tex](x + 3) {}^{2} = 27[/tex]
Take the sqr root of both sides
[tex]x + 3 = \sqrt{27} [/tex]
Subtract 3 from both sides
[tex]x = \sqrt{27} - 3[/tex]
Since a sqr root of a number can be positive or negative, the answer is
[tex] \sqrt{27} - 3[/tex]
or
[tex] - ( \sqrt{27} ) - 3[/tex]
A miniature golf course charges a flat rate of $5.00 for a putter and then $3.25 for every round of golf played. Write an equation in slope intercept form that shows the cost of playing x number of games.
Answers
slope intercept form is y=mx+b.
In the word problem, you have $5 as basically your non-negotiable fee, meaning $5 would be your y-intercept (also b).
Then you have 3.25, meaning each game is going to cost $3.25.
so for every game you play, it will cost you $3.25 with a add on fee of $5.00
A total of 584 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Answers
Answer:
584
Step-by-step explanation:
146 adult tickets were sold.
write out your equation first: x+3x=584
4x=584
x=146
Try it out 146+3(146)=584
It worked. That's the solution.
so lets divide the amount of tickets by 4 because there are 4 parts needed in this situation which equals 146 then we know our answer is 146 because the other three parts go to the kids tickets

Answers
Answer:
x = 2 and y = 2
Step-by-step explanation:
The given system of equations are :
12x+8y = 40 ...(1)
4x+5y = 18 ....(2)
Multiply equation (2) by 3.
12x+15y = 54 ...(3)
Subtract equation (1) by (3).
12x+15y-(12x+8y) = 54-40
12x+15y-12x-8y = 14
7y = 14
y = 2
Put the value of y in equation (2).
4x+5(2) = 18
4x+10 = 18
4x = 8
x = 2
The solutions of the given equations are x = 2 and y = 2

A building casts a shadow that is 50 feet in length. If the distance from the end of the shadow to the top of the building is 250 feet, what is the height of the building
Answers
Answer:
The height of the building is of 244.95 feet.
Step-by-step explanation:
We use the Pythagorean Theorem to solve this question.
We have that:
The shadow of 50 feet is one side of the right triangle, while the height h is other side.
The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.
So
[tex]50^2 + h^2 = 250^2[/tex]
[tex]h^2 = \sqrt{250^2 - 50^2}[/tex]
[tex]h = 244.95[/tex]
The height of the building is of 244.95 feet.

c. 0.45 = 45% probability that the person chosen at random has either type A or type AB blood
Step-by-step explanation:
a List the sample space for this experiment.
All possible blood types(A, B, AB or O). So
S = {A,B,AB,O}
b Make use of the information given above to assign probabilities to each of the simple events.
The proportions of blood phenotypes, A, B, AB, and O, in the population of all Caucasians in the United States are approximately .41, .10, .04, and .45, respectively.
So
P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45
c What is the probability that the person chosen at random has either type A or type AB blood
P(A) + P(AB) = 0.41 + 0.04 = 0.45
0.45 = 45% probability that the person chosen at random has either type A or type AB blood
