A discrete variable is a variable which may take only certain discrete values; for example the number of people in a household is a discrete variable which may have the value 1, 2, 3, etc. but cannot have intermediate values such as 1.473 or 3.732.
Choice d) can be represented by a discrete probability distribution, the other choices cannot be so represented.
Divide total km by the km in the scale:
112 / 16 = 7
The answer is A. 7 cm
4000. 25000 x .16 is 4000
Answer:
40 months
Step-by-step explanation:
Since it takes him 2 months to drive 15,000 miles
He drives 7,500 miles/month (15,000 miles / 2months)
Dividing the total distance by his speed yields the time it takes to drive that distance
300,000 miles / 7,500 miles/month = 40 months
Answer:
<em> 1005 girls</em>
Step-by-step explanation:
From the question we are given ratio of boys to girls as 7 : 29
Total ratio will be 7 + 29 = 36
Total students in the school = 1248 students
Number of girls in the school = 29/36 * 1248
Number of girls in the school = 29 * 35
Number of girls in the school = 1005
<em>Hence the approximate total number of girls in the school is 1005 girls</em>
<em></em>
<em>Note that the ratio was assumed since we are not given in question</em>
