Answer:
1. 8.3%
Step-by-step explanation:
Relative error = absolute error/expected measurement
The expected measurement is given as 6 ft.
Now, the absolute error is usually equal to half of a unit of the measure.
This means the absolute error in this case is ½ × 1 = 0.5 ft
Thus, the exact measurement will be;
6 ± 0.5
Thus;
Relative error = 0.5/6
Relative error = 0.083
Expressing it in percentage gives 8.3%
Number of boys enrolled is 105
<em><u>Solution:</u></em>
Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls
There are 245 total preschoolers
Ratio of boys and girls = 3 : 4
Number of boys : number of girls = 3 : 4
Let the number of boys be 3x
Let the number of girls be 4x
Total number of preschoolers = 245
Therefore,
number of boys + number of girls = 245
3x + 4x = 245
7x = 245
x = 35
Number of boys = 3x = 3(35) = 105
Thus number of boys is 105
Answer:the answers is 88 1/2
Step-by-step explanation:
Answer:
larger number is -5 and smaller one is -1
Step-by-step explanation:
x+y = -6
x = -6-y ....eqn i
x-y = -4...eqn ii
substituting eqn i in ii
x - y = -4
or, - 6 - y - y = -4
or, -6 - 2y = -4
or, - 2y = 2
so, y = -1
x + y = -6
x + (-1) = -6
so, x = -5
