let x be how much longer she can run the race and still beat her previous time
55(min) + x(min) < 1(hr) + 10(min)
55(min) + x(min) < 60(min) + 10(min)
55 + x < 60 + 10
x < 60 + 10 - 55
x < 15(min)
A.
You can use the rule:
So, let's do it:
Simplify:
And there you have it. If you need it one step further, then square 27, but take the parenthesis out.
If you need further help, feel free to ask for it.
Answer:
I believe the correct is A) The data is not symmetrical, so the mean is the best measure of center for the data.
Step-by-step explanation:
I am not 100% sure this is correct, if its wrong, im so sorry
1/3s+12=23
-12 on all sides
1/3s= 11
multiply reciprocal which is 3
s=33 <span />
Answer:
<em>The equation of the straight line in point - slope form</em>
<em>y +1 = -2 ( x-2)</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are C( 2,-1) and D(1,1)
Slope of the line
m = -2
<u>Step(ii):-</u>
Equation of the straight line passing through the point ( 2,-1) and having slope
m =-2
y - y₁ = m ( x- x₁)
y - (-1) = -2 ( x-2)
y +1 = -2 ( x-2)
<u><em>Final answer:-</em></u>
<em>The equation of the straight line</em>
<em>y +1 = -2 ( x-2)</em>
