The temperature at 12 am was 46 degrees. The temperature dropped steadily for the next 8 hours to reach the daytime low of 20 degrees. What was the temperature at 6am?​ (Pls include explanation)

Answers

Answer 1

Answer: 26.5 degrees

Step-by-step explanation:

This question can be solved using Arithmetic Progression.

Considers times 12am, 1am, 2am, 3am, 4am, 5am, 6am, 7am, 8am. (We take upto 8 am because the question says " next 8hours")

You will need to know the formula an = a + (n-1)d.

Take a=46 and a9=20 (n=9 here because there are 9 hours mentioned above)

Apply the values in the formula and you will get a + 8d = 20

Solve for d= -13/4

Now check which term does 6am comes. It is the 7th term.

Now solve for a7.

a7 = a + 6d

Apply the values you found earlier and you will get the final answer as 26.5

Hope it helps!

Weekly wages at a certain factory are
normally distributed with a mean of

Find the probability that a worker
selected at random makes between
$300 and $350.

Answers

Answer:

0.136

Step-by-step explanation:

If you have a calculator with statistical functions, this problem is straightforward.

Use the normcdf function as follows:

normcdf(300,350,400,50) = 0.136

This result is the probability that a worker makes between $300 and $350 per week:  0.136

All are true but the second one

The comparison of the given function and the graph is required.

It is true that y-intercept of both functions is 0.

It is false that the slope of both functions is [tex]\dfrac{3}{2}[/tex]

It is true that the graphs function has a greater rate of change.

It is true that point (0,0) is the point of intersection for both the functions.

Function and graphs

Two points of the graph are (0,0),(-2,-3).

The equation of the line is

[tex]y-0=\dfrac{-3}{-2}(x-0)\\\Rightarrow y=\dfrac{3}{2}x[/tex]

The other equation is [tex]y=\dfrac{2}{3}x[/tex]

Both the lines pass through the origin so the y intercept of both the functions is 0.

Only the slope of the function in the graph is [tex]\dfrac{3}{2}[/tex] the other function has slope [tex]\dfrac{2}{3}[/tex]

Writing the decimal forms of the slopes [tex]\dfrac{3}{2}=1.5[/tex] and [tex]\dfrac{2}{3}=0.67[/tex]

The function in the graph does have a greater rate of change.

Step-by-step explanation:

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?

A quick lesson on probability:

The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity  of flipping a coin and getting heads is:

(1 way to get heads) / (2 possible outcomes) = 1/2

Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.  

On to the problem.

There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.

Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.

Using the formula to find the probability, substitute the values we just found.

(the number of ways what you want can happen) / (total number of outcomes possible) =

(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.

Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black

7/20 * 100 = 35 times, or D
