Based on the result of the girl experiment, we can predict that if the same coin is tossed again as an independent experiment,
The probability of getting a head again is simply 33/60
Hope this helps
Answer:Height to width is 3:4
Width to height is 4:3
Step-by-step explanation:
A TV screen is 15 inches high and 20 inches wide.
Height of TV screen is 15 inches
Width of TV screen is 20 inches
To find ratio of Height to width
we replace the numbers in the ratio Height : width
15: 20
Divide both numbers by 5, so ratio becomes
3: 4
Height to width is 3:4
To find ratio of Width to height
we replace the numbers in the ratio Width : height
20:15
Divide both numbers by 5, so ratio becomes
4:3
Width to height is 4:3
The domain of the inverse of a function is the range of the original function
so find the range of f(x)
this is lowest to highest
we got the vertex is at (0,4)
and it goes to infinity
so range is from 4 to infinity
inverse
replace f(x) with y
switch x and y
solve for y
replace y with finverse
f(x)=x^2+4
y=x^2+4
x=y^2+4
x-4=y^2
y=√(x-4)
f⁻¹(x)=√(x-4)
inverse is f⁻¹(x)=√(x-4)
the domain is x≥4
The equation of the line in slope intercept form is y = -6x - 4
<h3>How to determine the equation of the line?</h3>
From the graph;
The line passes through the following points
(-1, 2) and (-2, 8)
The slope of the line is
m =(y2 - y1)/(x2 - x1)
So, we have
m = (8 - 2)/(-2 + 1)
Evaluate
m = -6
The equation of the line is
y = m(x - x1) + y1
So, we have
y = -6(x + 1) + 2
Evaluate
y = -6x - 4
Hence, the equation of the line in slope intercept form is y = -6x - 4
