A 95% confidence interval is found to be (30,36). The sample standard
deviation is 9, and the sample size is 36. If you wanted a smaller interval,
what could you do?
A. None of these
B. Decrease the sample size to 30.
C. Increase the sample size to 100.
D. Increase the confidence level to 99.7%.
Answer:
C
Step-by-step explanation:
A P E X
If you wanted a smaller interval, you could (c) Increase the sample size to 100
How to determine the true statement?The confidence interval is given as:
CI = 95%
The sample standard deviation is given as:
σ = 9
The sample size is given as:
n = 36
In a test of hypothesis, the higher the sample size, the smaller the confidence interval.
This means that an increase in the sample size from 36 would decrease the confidence interval
Hence, if you wanted a smaller interval, you could (c) Increase the sample size to 100

Kai sells a small magazine full of celebrity gossip to college students for $2.65 per copy. Hiring the printing press for one day, the only fixed cost, is $435 an issue. The variable cost of printing each issue is $0.82 per copy. The printer tells Kai the cost of hiring the press is to increase by $116 per day. If changing to color increases variable costs by $0.40, what is the percentage decrease in contribution margin resulting from the switch to color?
Answer:
Percentage decrease= 21.86%
Step-by-step explanation:
Giving the following information:
Selling price per unit= $2.65
Current variable cost= $0.82
Increase in variable cost= $0.4
To calculate the unitary contribution margin, we need to use the following formula:
Unitary contribution margin= selling price - unitary variable cost
Unitary contribution margin= 2.65 - 0.82
Unitary contribution margin= $1.83
New contribution margin= 2.65 - 1.22
New contribution margin= $1.43
Finally, the percentage decrease:
Percentage decrease= [1 - (1.43/1.83)]*100
Percentage decrease= 21.86%
How many solutions will there be to the following equation?
16x2 = 100
a. more than 2 solutions
b.
no solution
c. 1 solution
d. 2 solutions
Answer:
d. 2 solutions
+5/2,-5/2
Step-by-step explanation:
16x^2 = 100
x^2=100/16
x^2=25/4
X=√25/4
X=. +5/2,-5/2
So the answer is +5/2,-5/2

c - 3/4 = 1/8
Please answer
Answer:
The answer is 7/8.
Step-by-step explanation:
to get the answer you must use inverse operation so 3/4 + 1/8 = 0.875 or 7/8.
If this helped I would appreciate it if you marked me Brainliest. thank you and have a nice day!
Answer:
c = 7/8
Step-by-step explanation:
c - 3/4 = 1/8
First I will make sure that they all have the same denominator.
[tex]\frac{3}{4} * 2= \frac{6}{8}[/tex]
Our new equation will look like:
c - 6/8 = 1/8
Now we will add 6/8 to both sides.
c = 1/8 + 6/8
c = 7/8
Our final answer is:
c = 7/8

Bonita and Vince are jogging to school 2.5 miles west of
Vinces' house. It takes
them 15 minutes to arrive. As soon as they got there Boneta needed to run east
5 miles to the discount store for personal supplies. This took her 5 minutes. She
then slowly walks back to school, which takes her another 10 minutes
What is the average velocity in miles/min for Bonita for the entire trip?

What is her average speed in miles/min?
- Show how you convert the average speed to mis. Show your set up and answer.
Answer:
V_avg = 0.5556 miles/min
V_avg = 0.00926 miles/sec
Step-by-step explanation:
Bonita jogs 2.5 miles west of Vinces' house to school. It took her 15 minutes to arrive.
Speed 1; distance/time = V1 = 2.5/15 = 1/6 miles/min
Furthermore she ran 5 miles to the discount store for personal supplies. This took her 5 minutes.
Thus;
Speed 2; V2 = 5/5 = 1 mile/min
She then slowly walks back to school, which takes her another 10 minutes. Distance from the discount stor to school is 5 miles as stated in speed 2.
Thus;
Speed 3: V3 = 5/10 = ½ mile/min
Her average speed is;
V_avg = (V1 + V2 + V3)/3
V_avg = (1/6 + 1 + ½)/3
V_avg = 10/18 = 0.5556 miles/min
Converting to miles/seconds
60 seconds make 1 minutes, therefore 1 mile/min = 1/60 miles/seconds
Thus;
V_avg = 0.5556 miles/min = 0.5556 × 1/60 miles/sec = 0.00926 miles/sec

9. At the bowling alley, Angela rented shoes for $3 and it cost her $2.50 to bowl each game.
a) State an equation that represents the cost of bowling in the form C = mx + b, where C is the total
cost and x is the number of games bowled.
b) How much did it cost her to bowl four games?
Answer:
$13
Step-by-step explanation:
For the equation, m will be 2.50 and b will be 3. This is because 2.50 will change as she plays more games. The 3 will stay the same no matter how many games she plays.
C = 2.5x + 3
To find the cost to bowl four games, plug 4 into x and solve for C.
C = 2.5x + 3
C = 2.5(4) + 3
C = 10 + 3
C = 13

Which property is shown in the matrix addition below?
[-6 15 -2 ] + [6 -15 2 ] = [0 0 0
Answer:
The property shown in matrix addition given is "Additive Inverse Property"
Step-by-step explanation:
First of all lets define what a matrix is.
A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.
There are several addition properties for matrices.
One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.
Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.
[tex]\left[\begin{array}{ccc}-6&15&-2\end{array}\right] + \left[\begin{array}{ccc}6&-15&2\end{array}\right] = \left[\begin{array}{ccc}0&0&0\end{array}\right][/tex]
Hence,
The property shown in matrix addition given is "Additive Inverse Property"

2. Estados Unidos importa actualmente todo su café. La demanda anual de café por parte de los consumidores estadounidenses viene dada por la curva de demanda Q = 250 – 10P, donde Q es la cantidad (en millones de libras) y P es el precio de mercado por libra de café. Los productores mundiales pueden cosechar y enviar café a los distribuidores estadounidenses con un coste marginal (= medio) constante de 8 dólares por libra. Los distribuidores estadounidenses pueden distribuir a su vez el café a un precio constante de 2 dólares por libra. El mercado de café de Estados Unidos es competitivo. El Congreso está considerando la posibilidad de establecer un arancel sobre las importaciones de café de 2 dólares por libra.
a. Si no hay ningún arancel, ¿cuánto pagan los consumidores por una libra de café? ¿Cuál es la cantidad demandada?
b. Si se establece el arancel, ¿cuánto pagan los consumidores por una libra de café? ¿Cuál es la cantidad demandada?
c. Calcule la pérdida de excedente del consumidor.
d. Calcule los ingresos fiscales recaudados por el Estado.
e. ¿Genera el arancel una ganancia neta a la sociedad en su conjunto o una pérdida neta?
X - 2
x2-2x + 3
4.
x + 3
x + 3
Answer:
The equation is likely (x2 -2x -3)/(x+2) and to simplify you can do polynomial synthetic division or long division. Using long division because it works in all cases:
________
x+2√x2 -2x -3 how many times does x go into x2 , x times
x - 4 ______
x+2√x2 - 2x -3 multiply x by x + 2 and create the next row
-(x2 )
-4x - 3 bring down the -3 and repeat first step. how many times does x go into -4x, -4 times
-(-4x - 8) multiply x + 2 by -4
5 (this is the remainder but it must be in the form 5/(x+2)
so the answer is x - 4 + 5/(x + 2). Hopefully, this is what your teacher considers "simplified".
