Answer:
23.38 inches of fabric was used for headband for each player.
9.43 inches of fabric was used for wristband for each player.
Step-by-step explanation:
Given that:
Total fabric used on headbands = 888.44 inches
Total number of players = 36
Total number of coaches = 2
Total number of people for whom headbands were made = Number of players + Number of coaches = 36 + 2 = 38
Amount of fabric used for each one = Total fabric used for headbands divided by Total number of people
Amount of fabric used for each one =
Similarly,
Total fabric used on wristbands = 339.48 inches
Total number of players = 36
Amount of fabric used for each one = Total fabric used for headbands divided by Total number of players
Amount of fabric used for each one =
The given equation is:
X/Y = A/B
First, we will get rid of the denominators.
To do so, we will multiply both sides of the equation by YB
This will give:
XB = AY
We want to get the value of the Y. Therefore, we need to get rid of the coefficient of the Y which is the A. To do so, we will divide both sides of the equation by A.
This will give:
Y = XB/A
Comparing this result to the given choices, we will find that the correct choice is B
Answer:
$177.60
Step-by-step explanation: You have to get 3% of $1480 which is 44.4, then you multiply 44.4 by 4 since its 4 years and the result is 177.60.
Answer:
Step-by-step explanation:
Given that X the time to complete a standardized exam in the BYU-Idaho Testing Center is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
We have 68 rule as 2/3 of total would lie within 1 std deviation, and 95 rule as nearly 95% lie within 2 std deviations from the mean.
We have std deviation = 10
Hence 2 std deviations from the mean
= Mean ±2 std deviations
=±20
=
Below 50, 0.25 or 2.5% would complete the exam.
