A drug company is considering marketing a new local anesthetic. The effective time of the anesthetic the drug company is currently producing has a normal distribution with an average of 7.4 minutes. The chemistry of the new anesthetic is such that the effective time should be normal with the same standard deviation, but the mean effective time may be lower. If it is lower, the drug company will market the new anesthetic; otherwise, they will continue to produce the older one. A hypothesis test will be done to help make the decision.
A sample of size 36 results in a sample mean of 7.1 and a sample std deviation of 1.2.
Complete the 5 step hypothesis test at significance level 0.10; make and support your decision.
Step 1: Null and alternate hypothesis (H0 and HA):
Step 2: Level of Significance:
Step 3: Statistics Test/Statistics to be used:
Step 4: Rejection Criteria (draw normal curve; identify rejection area; state critical t value)
Step 5: Calculate t statistic; determine p-value; make decision about H0

The area of a circle is 132.7 square cm. Find the diameter.
13 cm (approximately)
Step-by-step explanation:
Let the radius of the circle be 'r'.
Area of the circle = πr²
=> 132.7 = (22/7) r²
=> 6.5 ≈ r
Therefore, diameter = 2radius = 2(6.5) = 13 cm

Write an inequality that represents `t`, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning
Question:
At midnight, the temperature in a city was 5 degrees Celsius. The temperature was dropping at a steady rate of 2 degrees Celsius per hour.
Write an inequality that represents t, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning.
Answer:
[tex]t > 4.5[/tex]
Step-by-step explanation:
Given
Let T = temperature and t = hours past midnight
So, we have:
[tex](t_1,T_1) = (0,5)[/tex] --- at midnight
[tex]m = -2[/tex] --- rate (it is negative because the temperature drops)
Required
Determine the inequality when the temperature is colder than -4 degrees
First, we calculate the hours when the temperature at -4 degrees
This is represented as:
[tex](t_2,T_2) = (t,-4)[/tex]
[tex](t_1,x_1) = (0,5)[/tex]
Using the slope formula, we have:
[tex]m = \frac{T_2 -T_1}{t_2 - t_1}[/tex]
[tex]-2 = \frac{-4-5}{t -0}[/tex]
[tex]-2 = \frac{-9}{t}[/tex]
Solve for t
[tex]t = \frac{-9}{-2}[/tex]
[tex]t = 4.5[/tex]
This implies that: at 4.5 hours, the temperature is at -4 degrees Celsius.
So, the inequality is:
[tex]t > 4.5[/tex]

Answer:
x = 42
y = 38.
I'm pretty sure this is the answer
Answer: x=42 y=48
Step-by-step explanation:
The angle with 42° and the blank space should add up to 90° so you would have to do 90-42=48° to find the blank space. As opposite angles are equal that means y=48° too.
Then to find out what x is you have to do 90-48=42° as the part with x and y in it has to add up to 90°.
You can check this by checking the two quarters. They should both add up to 90°.
42+48=90°
48+42=90°
So we know its correct.
Hope this helps :)

Solve for x. Pls and thank you
Answer:
x=4
Step-by-step explanation:
72 + 51 + 13x + 5 = 180
128 + 13x = 180
13x = 52
x = 4
Answer:
x = 4
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
72 + 51 + 13x + 5 = 180 add like terms
128 + 13x = 180 subtract 128 from both sides
13x = 52 divide both sides by 13
x = 4

0 - 1
1 - 4
2 - ___
3 - ___
4- ___
Answer:
2 - 9
3 - 16
4 - 25.
Step-by-step explanation:
I think you want this:
2 - (2+1)(2+1)
3 - (3 + 1)(3+1)
4 - (4+1)(4 + 1)
You substitute 2, 3 and 4 into x - (x+1)(x+1) and work them out.
Convert the degree measurement to radians. Express answer as multiple of
[tex]\pi = - 60 \: degrees[/tex]
Given:
The given degree measurement is -60 degrees.
To find:
The radian measure of the given degree measure.
Solution:
We know that,
[tex]\text{Radian measure}=\text{Degree measure}\times \dfrac{\pi}{180^\circ}[/tex]
The radian measure of -60 degrees.
[tex]\text{Radian measure}=-60^\circ \times \dfrac{\pi}{180^\circ}[/tex]
[tex]\text{Radian measure}=-\dfrac{\pi}{3}[/tex]
Therefore, the radian measure of the given degree measure is [tex]-\dfrac{\pi}{3}[/tex].

What are the coordinates of the vertex of the quadratic function having a minimum value of –1 and roots located at (–3, 0) and (–5, 0)?
plz help I'm really lost!
Answer:
The coordinates of the vertex will be (-4,-1)
Step-by-step explanation:
Let's recall that the vertex is in the middle point of the roots of a quadratic function.
The root are (-3,0) and (-5,0) so the x-value of the vertex will be:
[tex]x_{vertex}=\frac{-5-(-3)}{2}-3[/tex]
[tex]x_{vertex}=-1-3=-4[/tex]
The y-value of the vertex is given by the minimum value, that is -1
Therefore, the coordinates of the vertex will be (-4,-1)

ABCD is a parallelogram. If a CDA - 57 then BCD-_?
The diagram is not to scale.
133
57
114
123
Answer:
57
Step-by-step explanation:
It is given in the question that length CDA = 57.
Since the shape is a parallelogram, then we know that length AD=BC and AB=CD.
CDA = CD + AD
BCD = BC + CD
Since BC=AD and CD=CD
BCD = BC + CD is the same as CD + AD = CDA
Therefore BCD is the same length as CDA = 57
In other words, CDA is made up of a long side and a short side = 57
BCD is also made up of a long side and a short side, and since the longs sides are equal to each other and the short sides are also equal to each other in a parallelogram, BCD is the same length as CDA = 57.
Hope this helped!
