The graph is given in the attached image
<span>step 1 :</span> 3 • (x - 9) - 30 = 0
<span>Step 2 :</span><span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
3x - 57 = 3 • (x - 19)
<span>Equation at the end of step 3 :</span> 3 • (x - 19) = 0
<span>Step 4 :</span>Equations which are never true :
<span> 4.1 </span> Solve : 3 = 0
<span>This equation has no solution.
</span>A a non-zero constant never equals zero.
Solving a Single Variable Equation :
<span> 4.2 </span> Solve : x-19 = 0<span>
</span>Add 19 to both sides of the equation :<span>
</span> x = 19
One solution was found : <span> x = 19</span>
Answer:
About 91%
Step-by-step explanation:
According to the box plot provided :
Total number of students = 40
Minimum weight = 152 pounds
Third quartile (Q3) = 245
The approximate percentage of students that weigh 245 kg or less
About 10 of the intervals out of the 11 coverage interval of the box plot fall between 152 and 254 ; Hence,
(10 / 11) * 100
90.90
= about 91 % of the total students weigh 245 kg or less
Answer:
23
Step-by-step explanation:
3 * [2 + (12 - 2 * 4)] + 5
