Answer: 0.5
Step-by-step explanation:
Binomial probability formula :-
, where P(x) is the probability of getting success in x trials , n is the total trials and p is the probability of getting success in each trial.
Given : The probability that the adults follow more than one game = 0.30
Then , q= 1-p = 1-0.30=0.70
The number of adults surveyed : n= 15
Let X be represents the adults who follow more than one sport.
Then , the probability that fewer than 4 of them will say that football is their favorite sport,

Hence, the probability rounded to the nearest tenth that fewer than 4 of them will say that football is their favorite sport =0.5

Answer:
h = 7.1 cm
Step-by-step explanation:
To find the height of the triangle, we can first find the area of the triangle using the Heron's formula:

Where a, b and c are the sides of the triangle and p is the semi perimeter of the triangle:

So the area of the triangle is:


Now, to find the height, we can use the following equation for the area of the triangle:

The height draw in the figure is relative to the side of 17 cm, so this side is the value of base used in the formula. So we have that:



Rounding to the nearest tenth, we have h = 7.1 cm
