Answer:
2.263
Step-by-step explanation:
standard deviation of sample means = s/\sqrt{n}
Given
Standard deviation s = 16pounds
Sample size n = 50
Substituting
standard deviation of sample means = 16/\sqrt{50}
standard deviation of sample means = 16/7.071
standard deviation of sample means = 2.263
Hence the standard deviation of sample means taken from this population with a sample size of 50 is 2.263

An experimenter conducted a study of the relation of size in a particular species of bird to behavioral displays of dominance. The results for the first four birds observed were as follows:
Bird Size: 14 18 14 10
Bird Behavior: 74 82 74 70
Required:
a. Change the variable names to Bird Size and Bird Behavior
b. Make a scatter plot.
c. Compute the correlation
Answer:
Scatterplot is attached below
Correlation Coefficient = 0.0973
Step-by-step explanation:
Bird Size: 14 18 14 10
Bird Behavior: 74 82 74 70
The Correlation Coefficient, R = 0.973 ; which gives a very strong positive correlation between variable, x bird size and y, Bird Behavior.

In the following triangle, find the values of the angles Band B, which are the best approximations to the solutions to this ambiguous case?
Answer:
B. B = 70.5° or B' = 109.5°
Step-by-step explanation:
(sin 45°)/13.5 = (sin B)/18
sin B = (18 * sin 45°)/13.5
sin B = 0.9428
B = sin^-1 0.9428
B = 70.5°
B' = 180° - 70.5°
B' = 109.5°
20 men can complete a piece of work in 24 days how many men should be subtracted to finish the work in 32 days?
Answer:
5 men should be subtracted.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.
How many men should be working to complete the work in 32 days?
20 men - 24 days
x men - 32 days
Then
[tex]32x = 20*24[/tex]
[tex]x = \frac{20*24}{32}[/tex]
[tex]x = 15[/tex]
How many men should be subtracted?
There are 20 to complete in 24 days.
15 are needed to complete in 32 days.
20 - 15 = 5
5 men should be subtracted.

A point is chosen at random in the circle.
What percent of the time will the point be in
the square?
Round to the nearest tenth of a percent.
1 in.
[ ? ]%
Enter
Answer:
78.5%
Step-by-step explanation:
the percent of time the point will land in the square can be determined by dividing the area of the square by the area of the circle
A(circle) = 3.14(1)²
A(circle) = 3.14
A(square) = side squared
if radius of square is 1 inch then each side is 2 inches
A(square) = 2²
A(square) = 4 inches
3.14/4 = 78.5%

a school has 60 girls and 90 boys. the ratio of girls to boys
Answer:
60:90
Step-by-step explanation:
The ratio of girls (G) to boys (B) is 2 : 3.
Let the girls be represented by G.Let the boys be represented by B.Given the following data:
Number of girls = 60 girlsNumber of girls = 90 boysIn this exercise, you're required to find the ratio of girls (G) to boys (B). In order to do this, we would divide the two values to the least.
[tex]G : B = 60 : 90[/tex]
Dividing both sides by 30, we have;
[tex]G : B = \frac{60}{30} : \frac{90}{30} \\\\G : B = 2 : 3[/tex]
Therefore, the ratio of girls (G) to boys (B) is 2 : 3.

Aaron bought 7 packs of balloons for the party. There were 50 balloons in each bag. 40 of the total number of balloons were yellow. How many balloons were not yellow?
Answer:
[tex]total \: balloons = (50 \times 7) \\ = 350 \: balloons \\ none \: yellow \: balloons = 350 - 40 \\ = 310 \: none \: yellow \: balloons[/tex]
Answer:
310
Step-by-step explanation:
The equation that we would use to solve this problem is 7 × 50 - 40 = b
(b is the number of non-yellow balloons)
Since Aaron bought 7 packs of balloons with 50 balloons in each pack, we would need to multiply 7 and 50 to find the total amount of balloons that he bought.
7 × 50 = 350.
Now we subtract 40 (the total number of yellow balloons) from 350 (the total number of balloons), to find the amount of balloons that are not yellow.
350 - 40 = 310
