Required
The packages less than 30 kg.
To do this, we simply add up the frequencies of packages less than 30 kg.
From the chart, we have:
So, the total is:
Answer:
Step-by-step explanation:
<u>Point slope form</u>
y=mx +c, where m is the gradient and c is the y-intercept.
To find the gradient, use the formula below:
Substitute the value of m into the equation
To find c, substitute a coordinate into the equation.
When x= -3, y=7,
Thus, the equation of the line is
let n be the number of times letter be found (1800), p be the success rate (0.068), and q be the failure rate (1 - 0.068 = 0.932)
mean = np = 1800 x 0.068 = 122.4
standard deviation = √(npq) = √(1800 x 0.068 x 0.932) = 10.6807414
11 miles in 1/4 hour
1/4 of an hour is 15 minutes
so 11 in 15 minutes
x /60 = 11/15
cross multiply
x*15 = 60 * 11
15x = 660
divide both sides by 15
x = 44
the unit rate of the hikers in miles per hour is 44 mph.
You can also solve like this
1/4 of hour is 15 minutes
to get to the whole hour you would multiply by four
so you'd (11miles in 1/4 hour) * 4
44 miles in 1 hour
Hope this helps :)
