Answer:

It will take 42 minutes.

Step-by-step explanation:

In order to solve this we first have to calulate how long will it take one person to paint one wall:

54/6=9minutes

That is between 4 people it will take 9 minutes to paint a wall, one person alone supposing they all work at the same rate will take 36 minutes.

Now we just multiply that by the number of walls to be painted:

36*7=252

And we divide that by the number of people painting:

252/6=42

So it will take 42 minutes to paint 7 walls with 6 people painting.

ASAP PLEASE!!The table and the relative frequency histogram show the distribution of the number of tails and three coins are tos
snow_tiger [21]

Given:

The table and the relative frequency histogram show the distribution of the number of tails and three coins are tossed.

To find:

The probability P(T=3).

Solution:

In the given table T represents the number of tails.

From the given table it is clear that the value of probability is \dfrac{1}{8} and T=3. So,

P(T=3)=\dfrac{1}{8}

Therefore, the probability P(T=3) is equal to \dfrac{1}{8}.

Use the magnitudes​ (Richter scale) of the earthquakes listed in the data set below. Find the mean and median of this data set.
kvv77 [185]

Answer:

mean = 1.49

median = 1.53

Step-by-step explanation:

Using Excel, the procedure is the following

  1. Insert data set in a sheet. In my case I used cells A1 to AX1
  2. Compute mean with AVERAGE formula. In my case, AVERAGE(A1:AX1)
  3. Compute median with MEDIAN formula. In my case, MEDIAN(A1:AX1)

7.0 is an outlier because all data points are below 2.91

What is the slope of the line? y = 10​
Feliz [49]

Answer:

0

Step-by-step explanation:

The equation is written in slope-intercept form [ y = mx + b ]

In the equation [ y = 10 ], there is no variable that represents m and we know that because no number has an "x" after it.

The only number that could remove the variable of "m" and "x" would be 0.

Best of Luck!
