The australain sheep dog is breed renowned for its intelligence and work ethic it is estimate that 45% of adult australian sheep dogs weigth 65pounds or more asample of 15 adult dogs is studied what is the probalilty that more than 12 of them weigh 65 lb
Answer:
The probability is 0.0011 to 4 d.p
Step-by-step explanation:
Let p = probability of the dog weighing more than 65 pounds or more = 45% = 45/100 = 0.45
q is weighing less than = 1-p = 1 - 0.45 = 0.55
So the probability of more than 12 weigh 65 lb
That means 13, 14 or 15 weigh more than 65 lb
We can use Bernoulli approximation of Binomial distribution to get this;
That would be ;
15 C 13 0.45^13 0.55^2 + 15 C 14 0.45^14 0.55 + 15 C 15 0.45^15 0.55^0
= 0.001107024147 Which is approximately 0.0011 to 4 decimal place

Answer:
Angle 1- 130 degrees
Angle 3- 130 degrees
Angle 5- 50 degrees
Angle 6- 130 degrees
Step-by-step explanation:
Okay so. Angle 1 and 2 are on the same horizontal line. A line is 180 degrees. If two is 50 degrees then you subtract 50 from 180. Angles 2 and 4 are diagnol, which means that they are congruent, aka, the same, as are angles 1 and 3. 5678 and 1234 are the same. 1=8 2=5 3=6 and 4=7.

Lines l and k are parallel to each other. A=120 degrees. and C=80 degrees. What is the number of degrees in B??
100 points
Answer:
B = 160°
Step-by-step explanation:
This is how I solved it (I hope the explanation isn't too confusing):
Since L and K are parallel, I drew a straight line from A to B. By doing this, I'm making a triangle: ΔABC
Then I solved for the angles of the triangle. First, we are given that ∠C = 80° and ∠A = 120°. Although, when I drew the vertical line from A to B, it made a 90° (see attachment).
So what we basically did was break ∠A into two parts: an angle inside ΔABC and one outside. To find the interior angle, simply subtract 90° from 120° to get 30°.
There are 180° in a triangle, so add the two interior angles you know:
30° + 80° = 110°
Then subtract 110° from 180° to find the final interior angle which is:
180° - 110° = 70°.
To find the measure of angle B, you must add all of the parts together, so the 90° outside angle and the 70° interior angle:
90° + 70° = 160°

Answer:
x = 14°
y = 5°
Step-by-step explanation:
Angle COL is complementary to both 25° (∠AOC) and 5y (∠LOM). Then it must be true that ...
5y = 25°
y = 5° . . . . . . divide by 5

8 increased by the sum of t and 3
Answer:
8+(t+3)
Step-by-step explanation:
the sum is when you add two numbers together. so you would add t with 3 and out it in parentheses so you make sure that happens first. then you add it to 8 since 8 is being increased by the sum.

Answer:
Write the new equation in slope-intercept form. Replace the old slope with the new slope. Replace the y-intercept's value with a variable (b).
Answer:
the perpendicular slope will be the opposite reciprocal of the original slope .
Step-by-step explanation:
example: lets use the points (5,3) ( 10,7)
The slope is 5/4
so we need a line of -4/5 (perpendicular) that passes through 5,3

the amount of sleep that elementary school children get per night follows a normal distribution with a mean of 9.5 hours and a standard deviation of 0.55 hours. is it unusual for an elementary student to get at least 12 hours of sleep?
Answer:
Yes, that is unusual as the problem is given.
Step-by-step explanation:
If the mean is 9.5 and the standard deviation is 0.55, then anything within the normal curve of 10.05 on the high end and 8.45 on the low end is normal. 12 is more than several standard deviations or an outlier if this makes sense.
So, it is unusual as the problem is stated, but if it's a weekend, 12 hours is normal. LOL
Good luck!
Based on the normal distribution parameters given, the probability of a student getting atleast 12 hours of sleep ls 0. Hence, it is abnormal.
Given the Parameters :
Mean = 9.5 Standard deviation = 0.55Using the Zscore formula, the probability of getting a atleast 12 hours of sleep can be expressed thus :
Zscore = (Score - Mean) / standard deviation
For X ≥ 12 :
Z = (12 - 9.5) / 0.55 = 4.545The probability using a normal distribution table :
P(Z ≥ 4.54) = 1 - P(Z ≤ 4.54)
P(Z ≤ 4.54) = 1 ( normal distribution table)
P(Z ≥ 4.54) = 1 - 1 = 0
Since, the probability is 0 ; hence, it is unlikely and therefore, abnormal.

Solve the following inequality for g. Write your answer in simplest form.
-5-3(5g-4)≥2g+6-10
Answer:
[tex]g\leq \frac{11}{17}[/tex]
Step-by-step explanation:
[tex]-5-3(5g-4)\geq 2g+6-10\\-5+(-15g+12)\geq 2g-4\\-5+(-15g)+12\geq 2g-4\\7-15g\geq 2g-4\\7\geq 17g-4\\3\geq 17g\\\frac{11}{17} \geq g\\g\leq \frac{11}{17}[/tex]
The value of g in the given inequality -5-3(5g-4) ≥ 2g+6-10 is equal to or less than 11/17, g ≤ 11 / 17
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given is an inequality -5-3(5g-4) ≥ 2g+6-10
Solving for g,
-5-3(5g-4) ≥ 2g+6-10
-5-15g+12 ≥ 2g+6-10
-15g+7 ≥ 2g-4
7 ≥ 17g -4
11 ≥ 17g
11 / 17 ≥ g
g ≤ 11 / 17
Hence, the value of g is equal to or less than 11/17, g ≤ 11 / 17
