The Australian sheep dog is a breed renowned for its intelligence and work ethic. It is estimated that 4 0% of adult Australian sheep dogs weigh 65 pounds or more. A sample of 1 4 adult dogs is studied. What is the standard deviation of the number of dogs who weigh 65 lb or more?
Answer:
The standard deviation of the number of dogs who weigh 65 lbs or more is 1.83.
Step-by-step explanation:
Let X represent the number of adult Australian sheep dogs weighing 65 pounds or more.
It is provided that the probability of occurrence of X is, p = 0.40.
A sample of n = 14 adult dogs is studied.
Each dog's weight is independent of the others.
The random variable X follows a Binomial distribution.
The standard deviation of a Binomial distribution is:
[tex]\sigma=\sqrt{np(1-p)}[/tex]
Compute the standard deviation of the number of dogs who weigh 65 lbs or more as follows:
[tex]\sigma=\sqrt{np(1-p)}[/tex]
[tex]=\sqrt{14\times 0.40(1-0.40)}\\\\=\sqrt{3.36}\\\\=1.83303\\\\\approx 1.83[/tex]
Thus, the standard deviation of the number of dogs who weigh 65 lbs or more is 1.83.

Which shows a set of decimals ordered from least to greatest
A. 0.45 , 0.54 , 5.04
B. 0.54 , 0.45 5.04
C. 0.45 5.04 0.54
D. 0.54 , 5.04 0.45
Answer:
a. 0.45. , 0.54. , 5.04 is the answer
Answer:
a
Step-by-step explanation:
It's a because it starts with 0.45 (the least because if its just 45 than thats less than 54) and the greatest is 5.04 (you can think of them as 45, 54, and 504 but DON'T AVTUALLY DO THAT IN MATH).

−3 1/3⋅(−2 7/10) Please Help Me
Answer:
9
Step-by-step explanation:
Simplify the following:
-(3 + 1/3) (-(2 + 7/10))
Hint: | Multiply all instances of -1 in -(3 + 1/3) (-(2 + 7/10)).
(-1)^2 = 1:
(3 + 1/3) (2 + 7/10)
Hint: | Put the fractions in 2 + 7/10 over a common denominator.
Put 2 + 7/10 over the common denominator 10. 2 + 7/10 = (10×2)/10 + 7/10:
(3 + 1/3) (10×2)/10 + 7/10
Hint: | Multiply 10 and 2 together.
10×2 = 20:
(3 + 1/3) (20/10 + 7/10)
Hint: | Add the fractions over a common denominator to a single fraction.
20/10 + 7/10 = (20 + 7)/10:
(3 + 1/3) (20 + 7)/10
Hint: | Evaluate 20 + 7.
20 + 7 = 27:
(3 + 1/3)×27/10
Hint: | Put the fractions in 3 + 1/3 over a common denominator.
Put 3 + 1/3 over the common denominator 3. 3 + 1/3 = (3×3)/3 + 1/3:
27/10 (3×3)/3 + 1/3
Hint: | Multiply 3 and 3 together.
3×3 = 9:
((9/3 + 1/3)×27)/10
Hint: | Add the fractions over a common denominator to a single fraction.
9/3 + 1/3 = (9 + 1)/3:
27/10 (9 + 1)/3
Hint: | Evaluate 9 + 1.
9 + 1 = 10:
10/3×27/10
Hint: | Express 10/3×27/10 as a single fraction.
10/3×27/10 = (10×27)/(3×10):
(10×27)/(3×10)
Hint: | Cancel common terms in the numerator and denominator of (10×27)/(3×10).
(10×27)/(3×10) = 10/10×27/3 = 27/3:
27/3
Hint: | Reduce 27/3 to lowest terms. Start by finding the GCD of 27 and 3.
The gcd of 27 and 3 is 3, so 27/3 = (3×9)/(3×1) = 3/3×9 = 9:
Answer: 9
A bag contains 120 marbles some are red and the rest are black there are 19 red marbles for every black marble how many red marbles are in the bag.
Answer:
114 red marbles
Step-by-step explanation:
The ratio is 19:1
19+1=20
120/20=6
19(6)+1(6)=120
114+6=120
answer: 114 red marbles

PLEASE HELP
Equation A
Equation B
Equation C
<
Answer:
Step-by-step explanation:
Equation (A)
5(x - 6) + 3x = [tex]\frac{3}{4}(2x-8)[/tex]
5x - 30 + 3x = [tex]\frac{3}{2}x-6[/tex]
8x - 30 = 1.5x - 6
8x - 1.5x = 30 - 6
6.5 x = 24
x = [tex]\frac{24}{6.5}[/tex]
x = 3.69
Equation (B)
2.7(5.1x + 4.9) = 3.2x + 28.9
13.77x + 13.23 = 3.2x + 28.9
13.77x - 3.2x = 28.9 - 13.23
10.57x = 15.67
x = 1.48
Equation (C)
5(11x - 18) = 3(2x + 7)
55x - 90 = 6x + 21
55x - 6x = 90 + 21
49x = 111
x = 2.27
Solutions from these equations from least to greatest;
1.48 < 2.27 < 3.69
Equation (B) < Equation (C) < Equation (A)
Answer:
B, C, A

3. (03.06) Choose the point-slope form of the equation below that represents the line that passes through the point (6, -3) and has a slope of 1/2
Answer:
The answer is
[tex] \huge y + 3 = \frac{1}{2} (x - 6) \\ [/tex]
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question we have the final answer as
[tex]y + 3 = \frac{1}{2} (x - 6) \\ [/tex]

What is the slope of AC?pls help me
Answer:
The slope of AC is 2.
you go up 6 units and run 3 units
6/3 = 2
Answer:
Slope = 2.
Step-by-step explanation:
from the graph
x1 = 2 x2 = 5
y1 = 1 y2 = 7
Slope = (y2 - y1)/(x2 - x1)
= (7 - 1)/(5 - 2)
= 6/3
= 2.
