Let the length of one of the shorter pieces be
. Then, we know that two of the pieces are that length, and the third piece is
. Since these are all pieces of a rope, all we need to do to figure out the lengths is add all those together, solve for
, and then plug that back in to the desired lengths:
Shorter pieces:
Longer piece:
$91/ 7 = $13 per dog
$117/$13 = 9 dogs
He washed 9 dogs
Answer:
Answer:
(6,-7)
Step-by-step explanation:
The equation for reflecting an image about the origin is (a,b) to (-a,-b). It means you make x and y their opposites.
Step-by-step explanation:
6 yards is the answer
144π= πr^2*4 (formula)
the pi’s cancel out
divide 144/4
36=r^2
square root 36 to get rid of the r squared
r= 6 yd
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.
