About 10% of the human population is left-handed. Suppose a researcher speculates that artists are more likely to be left-handed
nevsk [136]

Answer:

Given the information in the question;

a) The parameter of interest is the population of artists who are left-handed and its is 10% = (10/1000 = 0.10

b) The Null hypothesis and alternative hypothesis are;

<em>H₀ : p </em>= 0.10

<em>H₁ : p</em> > 0.10

c) The sample proportion is calculated as:

p = number of left handed artist / sample size

p = 26 / 200

p = 0.13

d) To find the p-value, The researcher should calculate the probability that the sample proportion would be 0.13 or larger for a sample of size 200 if the population proportion is actually 0.10.

Michael’s father bought him a 16-foot board to cut into shelves for his bedroom. michael plans to cut the board into 11 equal si
liraira [26]
Alright, i subtracted 192 inches (total inch of board) by 11 (pieces) x .125t hen i divided by 11 and i got about 17.33 inches per boardand to answer the question, it will affect the total length of the board by -1.375 inches.

11x ( -.125) = - 1.375 inches then 192 - 1.375 = 190.625 then divide 190.625 / 11 = 17.33 inch

Happy studying ^_^

STALIN [3.7K]

Answer:

a. 9(2m+7)

b. 4(3r-1)

Step-by-step explanation:

When factoring out the greatest common factor of expressions, first list the factors of the terms. Then, determine the greatest common factor between the two terms. After, "carry" that number out of the expression through division.

a. 18m+63

Start by listing the factors of 18 and 63.

18: 1, 2, 3, 6, 9, 18

63: 1, 3, 7, 9, 21, 63

The greatest common factor of 18 and 63 is 9, so we can carry 9 out of the expression through division:

18m+63

= 9(2m+7)

b. 12r-4

Start by listing the factors of 12 and 4.

12: 1, 2, 3, 4, 6, 12

4: 1, 2, 4

The greatest common factor of 12 and 4 is 4, so we can carry 4 out of the expression through division:

12r-4

= 4(3r-1)

I hope this helps!
