4*1.15=4.6 - amount of gravel used by 4 trucks
2*0.7=1.4 - amount of sand used by 2 trucks
4.6+1.4=6 - Total amount of materials
6- final answer

Answer:
The mode = 24
Probability = 0.14
Probability = 0.74
Step-by-step explanation:
Mode is 24 because it has the highest frequency.
The probability of winning a score of 25 = 7/50 = 0.14 = 14%
Probability of winning sore of 23+ = 37/50 = 74% = 0.74
Hope this helps.
Good luck
Answer:
<h2>3.6</h2>
Step-by-step explanation:
It can be seen from the diagram that ΔDAC and ΔABD are right angled triangle.
Using the SOH, CAH, TOA trigonometry identity on ΔDAC where;
AC is the hypotenuse = 5.1
CD is the opposite (since it faces the angle directly)
According to SOH;
Sin = opp/hyp
sin
∠DAC = ∠BAD = 38.9°
According to ΔABD, the opposite side is DB which is unknown and the hypotenuse id AB i.e 5.7
Using SOH;
BD ≈ 3.6 to one dp
If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.
If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)
If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)
