Answer:
A,C,D
Step-by-step explanation:
Complete Question:
<em>"Which pairs of points would result in a line with a rate of change of 2:1? select all that apply"</em>
<em>A.(−4,−11) and (−2−7)
</em>
<em>B.(5,6) and (−5, 12)
</em>
<em>C.(0,−3)and (−4,−11)
</em>
<em>D. (0,−3) and (5, 7)</em>
<em />
Rate of change is the slope. 2:1 would mean a slope of simply, 2.
We need to find slope of each of the choices from A - D and see which one has 2. The formula would be:
Where m is the slope and
x_1 is first x point
x_2 is second x point
y_1 is first y point
y_2 is second y point
Let's calculate slope of each of the choices.
A.
THis one is okay.
B.
THis one is not 2:1.
C.
THis one is okay.
D.
This one is okay.
Hence, A, C, and D all have rate of change of 2:1
(4x28)+64
112+64
176
Rounded to the nearest ten it would be 180
Answer:
Step-by-step explanation:
Hello!
The variable of interest is
X: air pressures of properly inflated sports balls.
<em>Average recommended psi Tolerance
</em>
<em>(pounds per square inch)
</em>
<em>Soccer ball 12.05
±3.55
</em>
<em>Basketball 8.00
±0.5 </em>
<em>Volleyball 4.44
±0.18</em>
Each recommendation is expressed like the "average air pressure" ± "standard deviation of the recommended air pressure" so if you express it in inequality it will be:
X[bar]-S ≤ X ≤ X[bar]+S
So for each ball type, you can write it as:
<u>Soccer ball</u>
12.05-3.55 ≤ X ≤ 12.05+3.55
8.5 ≤ X ≤ 15.6
<u>Basketball</u>
8.00-0.5 ≤ X ≤ 8.00+0.5
7.5 ≤ X ≤ 8.5
<u>Volleyball</u>
4.44-0.18 ≤ X ≤ 4.44+0.18
4.26 ≤ X ≤ 4.62
I hope this helps!
In your "<span>^25Log27=a , then ^3log5," your " ^ " has been twice misplaced. The symbol " ^ " always goes between your base (on the left) and your exponent (on the right." Would you please go back to the original question and ensure that you have copied this problem exactly as it was given.</span>
The probability would be 1/2
