Answer:

1 17/42.

Step-by-step explanation:

Find the common denominator, which is 42.

So change -4 1/6 to -4 7/42.

And change 5 4/7 to 5 24/52.

So add -4 7/42 + 5 24/52 and you'll get: 1 17/42.

(The decimal form of this is 1.404762)

If a variable has a distribution that is​ bell-shaped with mean 28 and standard deviation 5​, then according to the Empirical​ R
mars1129 [50]

Answer:

99.7% data lies between 13 to 43

Step-by-step explanation:

Mean:  \mu = 28

Standard deviation : \sigma = 5

68% of data lies between \mu - \sigma to \mu +\sigma

95% of the data lies between \mu - 2\sigma to \mu +2\sigma

99.7% data lies between  \mu - 3\sigma to \mu +3\sigma

We are supposed to find  99.7 of the data will lie between which​ values

99.7% data lies between  28 - 3(5) to 28 +3(5)

99.7% data lies between  13 to 43

Hence 99.7% data lies between 13 to 43

Help ASAP please ! Explain too for brainlist
musickatia [10]

Answer:

Ok so im not the best at explaining but its worth a shot

C)25

Step-by-step explanation:

we already know that the formula to find area is

A=l*w

and that every square is 1 square unit.

So in the first part on the far left, you count down 8 and over 2 to find how many total squares are shaded. This is the length and width of that one part  so you multiply 8*2 to get 16.

In the next part, you should count starting at -1 over to 5 to get 6. It only has a width of 1 so 6*1 is still 6.

In the last part you start counting at -3 and count down to -6 and this gives you 3. It is 1 unit wide so 3*1 is 3.

Add 16+6+3 together because that is the combined area of the 3 parts and we get 25

Like i said im definitely, by no means, the best at explaining but if this helped even a little that's awesome, if you have any particular questions i can try to answer them in the comments
