Answer:
TW +DW
Step-by-step explanation:
If this is the only information you are given then no. This is because the < sign means that p is less than 2. The second sign cannot be true if the first one is because the second sign says that p is less than or equal to 2.
Answer:
0.677
Step-by-step explanation:Add up the values in the plan A column. There are 10+12+16 = 38 people who prefer plan A.
Add up the values in the "40-49" row to find that 16+8 = 24 people are ages 40 to 49.
We have 38+24-16 = 46 people who either prefer plan A, are aged 40-49, or fit both descriptions. I subtracted off 16 because those 16 people were counted twice when adding 38 and 24.
An alternative way to get this value of 46 is to add up everything that is in column1 or row 3 (or both). So that would get 10+12+16+8 = 46.
Now add up everything in the table to find out how many people were surveyed total. That would be 10+7+12+15+16+8 = 68 people overall.
The probability of someone liking plan A, or being age 40-49, or both is 46/68 = 0.6765 approximately. Rounding to 3 decimal places gives 0.677
Answer:
the explanation is given below.
Step-by-step explanation:
- Here what is applied is assumption of range of values of number from say 1 - 100
- In total, i stopped at 100 on the dot.
from this, the lowest number is 1 and the highest number is 100
- hence the range of the numbers = Difference between Highest and Lowest
- range = 100 - 1 = 99, the 99 gotten as the range is indicative that a number has been missing.
- In order to make up the 100, an integer is added to the difference = 99, i.e 99 is added to 1 to make up the 100.
- Furthermore, if 0 is exclusively out when numbers are counted up 100 with 0 inclusive, in such case, the first and last number are excluded from the counting. as such the integers will be {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20.........., 99} since both 0 and 100 are not included.
- Here, if we try to get the range = highest - lowest = 99 - 1 = 98, it implies that to make up the 99, an integer is added to the result of the difference = 98+1 = 99
- As such, the number of integers between two numbers is the difference between the highest and the lowest number plus 1 i.e highest - lowest + 1 = y - x +1 = (the floor of y) - ( the ceiling of x) + 1
The answer is x:8
Solution
Kite formula : 1/2(d1 x d2)
D1=15
D2=x
60=1/2 x15 x x
X=60x2/15
X= 4 x2
X=8
Do you have any doubt?
