Two competing headache remedies claim to give fast-acting relief. An experiment was performed to compare the mean lengths of time required for bodily absorption of brand A and brand B. Assume the absorption time is normally distributed. Twelve people were randomly selected and given an oral dosage of brand A. Another 12 were randomly selected and given an equal dosage of brand B. The length of time in minutes for the drugs to reach a specified level in the blood was recorded. The results follow: x s x n Brand A 20.1 8.7 12 Brand B 18.9 7.5 12 a) Is there sufficient evidence that these drugs differ in the speed at which they enter the blood stream?

Step-by-step explanation:

Diego has run 4/5 of a race distance. He has run 7 2/3 ​

Answers

Your question is incomplete, but I am guessing that it reads something like:

“Diego has run 4/5 of a race distance. He has run 7 2/3 miles. How long is the race? Or “how many miles does he have left?”

How long is the race? = 9 7/12 miles

4/5x = 7 2/3
4/5x = 23/3
x = 23/3 • 5/4
x = 115/12
x = 9.58333
x = 9 7/12 miles

How many miles does he have left? = 1 1/12 miles


1/5 • 115/12 = 115/60 = 1.916666
= 1 55/60 = 1 11/12 miles

A. 19°
B. 20°
C. 26°
D. 28°

Answers

Answer:

A. 19°

Step-by-step explanation:

To find the average of something, you add every number in the sequence and then divide it by how many numbers there are.

23 + 17 + 26 + 5 + 33 + 11 = 115

115 / 6 = 19.16666666666667

Round it down and your answer will be 19°.

Find the volume of cylinder with height 9 cm and radius 4 cm

Answers

Answer: 144π

Step-by-step explanation: First. find the area of the bases. To do this, you must solve for the area of a circle with a radius of 4. Since the formula for finding the area of a circle is area=πr² squared, the area of the circles are 16π. Next, you must multiply the area of the base, 16π, by the height of the cylinder, 9. 16π times 9 is 144π, or about 452.4, if rounded to the nearest tenth, or 452.39, if rounded to the nearest hundredth.

Answer:

x= -1+- i√35/2(looks weird so I'll include an image)

Step-by-step explanation:

depends on what you wanted to do with this equation, but I'm going to assume you wanted to factor this.

(-b+- √b^2-4ac)/(2a)=

-1+- √1- 4(1)(9)/ 2=

-1+- √1- 36/ 2=

x= -1+- i√35/2

-20t > -80
can you solve this and graph it​

Answers

Given:

The inequality is:

[tex]-20t>-80[/tex]

To find:

The solution for the given inequality and graph of it.

Solution:

We have,

[tex]-20t>-80[/tex]

Divide both sides by -20 and change the sign of inequality because inequality is divided by a negative number.

[tex]\dfrac{-20t}{-20}<\dfrac{-80}{-20}[/tex]

[tex]t<4[/tex]

Therefore, the solution for the given inequality is [tex]t<4[/tex].

All the value less than 4 are in the solution set. It means all the values on the left side of 4 are in the solution set.

Since 4 is not included in the solution set, therefore there is an open circle at 4.

The graph for the given inequality is shown below:

Can someone answer this

Answers

Answer:

y = 2x + b (the second answer choice)

Step-by-step explanation:

The slope-intercept form is y = mx + b (the m representing slope and the b representing y-intercept). Put the points in ratio form as a fraction and subtract the ratio with the smallest numbers from the ratio with the largest ratio (5/1 - 1/-1) to get 4/2. When simplified, it becomes 2/1, so the slope is 2. Using the slope found previously, subtract 1 from the x of (1, 5) and 2 from the y of (1, 5) to get the y-intercept. The resulting point is (0, 3), so the y-intercept is 3. Replace the m with the found slope (2) and b with the found y-intercept (3) to end up with y = 2x + 3.

On the other side of the coin, organizations have to act when an employee's performance consistently falls short. Based on these concepts, organizations may distinguish between involuntary and voluntary turnover, recognize their effects on the organization, develop measures to encourage top performers to stay, and develop ways to manage the separation process fairly. Any organization wants to retain good performers and encourage or force low-performing employees to leave. There are two types of employee turnover. Involuntary turnover occurs when the employer requires employees to leave, often when they would prefer to stay. This action may potentially result in lawsuits and violence. Voluntary turnover occurs when employees initiate the turnover, often when the organization would prefer to keep them. These employees may retire or leave to work with different organizations.
