Answer:
43.98
Step-by-step explanation:
Answer:
Well I figure you would use a ratio. we are given one when comparing 240 lbs to 180 calories for each mile:
240lbs/180calories = 1 mile
we.are.given another when saying a person. burns 36 calories in 1 mile. we don't know weight so we will say x lbs:
x/36calories = 1 mile
since they both equal 1 mile we know they are equal:
240/180 = 1 = x /36
we can get rid of the 1 in between and say:
240/180 = x/36
let's reduce first fraction
8/6 = x/36
cross multiply:
8*36 = 6x
divide both sides by 6
8*6 = x
x = 48
Step-by-step explanation:
For a line with slope m that passes through a point
, the point-slope form equation is the following.
We have a given slope of 4 and a given point of (7,5). Now, plug in the values.
That is the
point-slope form of the line. Now, let's change this into slope-intercept form. Slope-intercept form looks like the following:
Where m is the slope and b is the y-intercept. Let's do some algebra on our point-slop form equation to change it into slope-intercept form.
This was our equation. Let's use the distributive property on 4(x-7).
Now, add 5 to both sides of the equation
This the
slope-intercept form of the line. Thus, we have solved for both the point-slope form and the slope-intercept form. Hope this helps! :)
Answer:
There is a 25.92% probability that exactly 4 of the selected adults believe in reincarnation.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe in reincarnation, or they do not believe. This means that we can solve this problem using the binomial probability distribution.
Binomial probability distribution:
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem
There are 5 adults, so
60% believe in reincarnation, so
What is the probability that exactly 4 of the selected adults believe in reincarnation?
This is P(X = 4).
There is a 25.92% probability that exactly 4 of the selected adults believe in reincarnation.
