The two-way frequency table represents data from a survey asking mall visitors whether they like seafood, meat, or both. A 4-column table with 3 rows. The first column has no label with entries seafood, not seafood, total. The second column is labeled meat with entries 16, 20, 36. The third column is labeled not meat with entries 31, 5, 36. The fourth column is labeled total with entries 47, 25, 72. Which is the joint relative frequency for mall visitors who like seafood and meat? StartFraction 5 Over 72 EndFraction StartFraction 16 Over 72 EndFraction StartFraction 20 Over 72 EndFraction StartFraction 31 Over 72 EndFraction

Option B.

Step-by-step explanation:

The given table is

                          Meat              Not meat         Total

Seafood               16                      31                  47

Not seafood        20                      5                  25

Total                     36                    36                  72

From the given table it is clear that:

Seafood-Meat = 16

Not seafood-Meat = 20

Seafood-not meat = 31

Not seafood- not meat = 5

Total = 72

We need to find the joint relative frequency for mall visitors who like seafood and meat.

Joint relative frequency

Joint relative frequency

Therefore, the correct option is B.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
