Answer:
20
Step-by-step explanation:
Answer:
And from this case we can see that the deviation is given by:
Step-by-step explanation:
For this case we have the following notation given:
And from this we know that the distribution for the random variable is normal and we know that in general the normal distribution is given by:
And from this case we can see that the deviation is given by:
<u>Given</u>:
Given that the pie chart shows the relative frequency distribution resulting from a survey of 6000 US rural households with internet connections in a certain year.
We need to determine the total number of households with each type of internet in the survey.
<u>Cable modem:</u>
Since, the relative frequency distribution for cable modem is 0.142
The total number of households that use cable modem is given by
Thus, 852 households use cable modem.
<u>DSL</u>:
Since, the relative frequency distribution for DSL is 0.092
The total number of households that use DSL is given by
Thus, 552 households use DSL.
<u>Dialup</u>:
Since, the relative frequency distribution for dialup is 0.747
The total number of households that use dialup is given by
Thus, 4482 households use dialup.
<u>Others</u>:
Since, the relative frequency distribution for others is 0.019
The total number of households that use others is given by
Thus, 114 households use others.
Answer:
Acute and Scalene
Step-by-step explanation:
Acute bc its less than a 90 degree angle
Scalene bc all sides are of unequal length
Answer:
29 units²
Step-by-step explanation:
You could divide this into two triangles and two trapezoids to find the area. But since the majority of these are either whole or half squares, I‘d count those. Then you’d just have one triangle in the top right corner.
Whole squares: 21
Half Squares: 10 (so 4 square units)
Triangle: 1/2(b)(h)=1/2(5)(2)=5
TOTAL = 21+4+5= 29 units²
