Answer:
5/21
Step-by-step explanation:
1. 5/7 divided by 3 is the same as 5/7 divided by 3/1
2. when dividing a fraction, multiply by the reciprocal, so it would be 5/7 times 1/3
3. multiply the numerator and denominators, so 5x1 and 3x7
4. the answer is 5/21
hope this helped!
Answer:
the incidence rate is 28.47
Step-by-step explanation:
The computation of the monthly incident rate of active cases is shown below:
Incidence rate is
= 1325 ÷ (47175 - 642) × 1000
= (1325 ÷ 46533 ) × 1000
= 28.47
hence, the incidence rate is 28.47
Answer:
The finish line
Step-by-step explanation:
Jonas is planning his trip using the finish line as reference point. He is using an interval scale (using meters as measurement) and the finish line = 0 meters or the starting point. Anything before the finish is negative and anything after is positive. In this case, his wife is located at 91 + 14 = 105 meters away from him. When you use an interval scale to measure distance, you must use absolute values to determine the distance because positive and negative points.
Answer: x=8
How: 41 the triangles are mirrored, so they have the same angles. You are trying to find the bottom angle of the top triangle, which is the same as the top angle of the bottom triangle since they are mirrored. So, (5x+1) is equal to 41. 41-1 =40. 40/5=8. Boom.
Answer:
A. Increase the level of confidence
Step-by-step explanation:
The margin of error is given by:
The margin of error is:
In which T is related to the level of confidence(the higher the level of confidence, the higher T is), s is the standard deviation of the sample and n is the size of the sample.
Increase the width:
That is, increasing the margin of error, as the width is twice the margin of error, the possible options are:
Increase T -> increase confidence level.
Increase s -> Increase the standard deviation of the sample.
Decrease n -> Decrease the sample size.
Thus, the correct answer is given by option A.
