A cosmetics company conducted a survey to anticipate potential sales of various new products from its upcoming catalog. The survey was conducted by randomly selecting women from two different age groups with 400 women in each group. The women selected the product that they would most likely purchase when it became available. The results obtained are given in the table shown below.
Products Ages 21 - 30 Ages 31 - 40
Product 1 163 152
Product 2 84 89
Product 3 104 109
Product 4 49 50
Which of the following statements about the data above is true?
A.
The estimates for both age groups show an equal number of women would have voted for Product 3.
Answer:
The shortest walking route is through the diagonal AC: 102.89m
Step-by-step explanation:
One can go from A to C using 2 paths:
- ADC or ABC
- using diagonal AC and half of that inner circle.
We need to compute the length of each path.
1) ADC=AD+DC=80+50=130m
2) AC²=AD²+DC²=80²+50⁵=6400+2500= 8900m²
AC=sqrt(8900)=94.34m.
Note that the diagonal AC has a missing segment, whose length is the diameter of the inner circle. So the straight line has a length of: AC-d=94.34-15=79.34m.
Perimeter of half the circle=pi×r= 3.14×(15/2)= 3.14×7.5=23.55m
So, if one is using the diagonal to go from A to C, then he has to walk:
79.34+23.55=102.89m
Comparing the two routes: 130m vs 102.89m, we notice that the route using the diagonal AC is shorter.
Answer:
1/4(8/3+9)-3
Step-by-step explanation:
1/4(8/3+9)-3
Answer:
b = 72
Step-by-step explanation:
It is a linear equation in one variable, b. Maybe you want the solution.
Multiplying the equation by 24, we get ...
9b +4b +10b = 1656
23b = 1656 . . . . collect terms
b = 72 . . . . . . . . divide by 23
