Answer: The difference between M and mu is due to the sampling error is <u>-6.59 .</u>

Step-by-step explanation:

As per given:

in population, the average number of minutes spent in active play on weekends is μ = 65.87

In sample, the average number of minutes the children spend in active play on weekends is M = 59.28

Now, the difference between M and μ is due to the sampling error is M- μ

= 59.28 - 65.87

= -6.59

So, the difference between M and mu is due to the sampling error is <u>-6.59 .</u>

Find the missing factor

Yuki888 [10]

Answer:

The missing factor is (9s+1)

Step-by-step explanation:

The missing factor is (9s+1) because of the following

(9s^2 + s) + (18s+2)

If we factor out s from 9s^2+s, we get s(9s+1).

If we factor out 2 from 18s+2, we get 2(9s+1)

putting these together, we get s(9s+1) + 2(9s+1). Factoring out the common term of 9s+1, we get (9s+1)(s+2). therefore, the missing factor is 9s+1

Fill in the missing numbers along the sides of the triangle so that it contains each of the numbers from 4 through 12 exactly on

elixir [45]

Answer: A B == 9 + 11 CD == 5 +7 E F == 6 + 10

Step-by-step explanation:

(This reminds me of a "formula" I developed a few years ago when I was photographing formal groups, and had to figyre out how many people to put in each row, and the rows had to be different lengths) Anyway--

Get the sum of the numbers at the angles, subtract that number from 32, and that's the amount needed for the row.

Once I have that number, divide by 2 and split as "n + 1 and n-1

AB side: angles given: 8 +4=12 , 32-12 =20 20/2 = 10; 10+1 =11 10-1=9

CD side: angles given: 8 + 12 =20, 32-20=12; 12/2 =6 6+1 =7 6-1 =5

EF side: angles given: 4 + 12 =16 32-16=16 My formula would have yielded 7+9, but those numbers were already used. Conveniently, 10 + 6 are left over. Same principle, but + or - 2.

Thanks for the opportunity to work in this!

A ball is thrown into the air with an upward velocity of 48 ft/s. Its height h in feet after t seconds is given by the function

stiv31 [10]

The answer to this, your question is h = -16t • 2 + 48t + 6
h = -32t + 48t + 6
h = 16t + 6 HOPE I HELPED IN A WAY! ~Marcey<3
