Answer:
The expected participation rate is 0.637.
The standard error is 0.04397
Step-by-step explanation:
For each working age people asked, there are only two possible outcomes. Either they are in the labor force, or they are not. This means that we can solve this problem using binomial distribution probability concepts.
Binomial probability:
Expected value for the participation rate: The expected value is the probability of a success. In this problem, a success is a working age people being in the labor force. 63.7% of them are. So . This means that the expected participation rate is 0.637.
Standard error for the participation rate:
The standard error is given by the following formula:
.
In this problem, 120 people are asked, so
.
So the standard error is 0.04397
Answer: x= 25
Step-by-step explanation:
28+47+ y(some number)= 180
solve for y to get 75 and since 75=3x x=25
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
The radius of the base of a cone is 4 inches. The slant height of the cone is 6 inches. Which is closest to the surface area of the cone ?
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>
<h3>Given:-</h3>
Radius (r) of the base of a cone is 4 inches.
Slant height (l) of the cone is 6 inches.
<h3>To Find:-</h3>
Which is closest to the surface area of the cone ?
<h2>Solution:-</h2>
We know,
Formula of surface area of a cone is πr(r + l) sq. units.
Taking value of π = 3.14
So, Surface area of the cone = 3.14 × 4(4 + 6)
Surface area of the cone = 12.56 × 10
Surface area of the cone = 125.6 sq. inches.
126 sq. inches is closest to 125.6 sq. inches.
So, option (H) <u>1</u><u>2</u><u>6</u><u> </u><u>s</u><u>q</u><u>.</u><u> </u><u>i</u><u>n</u> is correct. [Answer]
The part you don't need is "there are 10 periods in all during a week" because once you read the first two sentences you can tell you just need to do 24 x 2 which equals 48.
*Hope i helped :D
Answer:
49°
Step-by-step explanation:
