Loia Piaza surveyed 872 customers to determite which of two new pizza cnoices to 425 said they would prefer the BBQ Ranch Pizza.

Firdavs [7]

Answer:

Correct option: fourth one -> 87.6% (it is missing the point between 7 and 6)

Step-by-step explanation:

We have a total of 872 customers surveyed, and from this total, 384 were male, so the number of female is 872 - 384 = 488

From the 488 female, we know that 171 females prefer the Buffalo pizza, so the number of females that prefer the bbq pizza is 488 - 171 = 317.

If 425 customers prefered the bbq pizza, we know that the number of customers that prefer the buffalo pizza is 872 - 425 = 447

To find the probability of a customer being female or prefering the buffalo pizza, we can use this formula:

N(female or buffalo) = N(female) + N(buffalo) - N(female and buffalo)

N(female or buffalo) = 488 + 447 - 171 = 764

So the probability of chosing a female or someone that prefer buffalo is:

P = N(female or buffalo) / N(total) = 764 / 872 = 87.6%

Correct option: fourth one (it is missing the point between 7 and 6)

ritu can row downstream 20km in 2 hrs and upstream 4km in 2 hrs. find the speed of rowing in still water and the speed of the cu

Marina CMI [18]

Answer:

Speed of boat in still water is 6km/h

Speed of current is 4km/h

Step-by-step explanation:

We know speed = distance / time

Let the speed of boat in still water be x

Let the speed of current be y

Hence the speed of boat, down stream = $x+y$

Distance downstream = 20km

Time taken = 2 hours

We have

$x+y=\frac{20}{2}$

$x+y=10$ ......(1)

Speed of boat upstream = $x-y$

Distance upstream = 4

Time taken = 2

We have

$x-y=\frac{4}{2}$

$x-y=2$ ...(2)

Adding (1) & (2)

$2x=12$

$x=6$

Substituting in (1) we get

$y=4$
