Answer:
24
Step-by-step explanation:
30 secs = 0.5 min
thus 84 / 3.5 min = 168 / 7 = 24
Answer:
a) 4
b) 12
Step-by-step explanation:
Since, when an orange ball is drawn, three coins are tossed. So, sample points are
OHHH, OHHT, OHTH, OHTT. OTHH, 0THT, OTTH, OTTT
So, clearly, 8 sample points will have an orange ball.
When a blue ball is drawn, two coins are tossed. So, sample points are BHH,BHT,BTH,BTT.
So, clearly, 4 samples points will when a blue ball is drawn.
Total samples points=4+8=12
Answer:
Coordinates involve two points. (x,y)
Too find a pair (coordinate), use the x and y lines on the graph and see where the point falls.
For example
Point A is number <em>1</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>y</em><em> </em><em>axis</em>
<em>number</em><em> </em><em>-</em><em>4</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>axis</em>
<em>So</em><em>,</em><em> </em><em>you</em><em> </em><em>would</em><em> </em><em>write</em><em> </em><em>the</em><em> </em><em>coordinate</em><em> </em><em>out</em><em> </em><em>at</em><em> </em>
<em>(</em><em>-</em><em>4</em><em>,</em><em>1</em><em>)</em>
The y axis values are the second point, so after you plot all of letters, use the y axis numbers and number them from least to greatest so you can find the mystery word.
Answer:
OPTION D: NEITHER
Step-by-step explanation:
The given equation is: 7x - 2y = - 5
To find a solution to this, we substitute the options and compare LHS and RHS.
OPTION A: (1, 5)
LHS = 7(1) - 2(5) = 7 - 10 = -3
RHS = - 5
LHS 
RHS.
So, this option is eliminated.
OPTION B: (-1, 1)
LHS = 7(-1) - 2(1) = -7 - 2 = - 9
RHS = - 5
Again, LHS RHS.
So, this Option is eliminated as well.
OPTION C: It says both A and B. Clearly, this is eliminated as well.
Therefore, the answer is: OPTION D: NEITHER.
NOTE: This is a two variable equation. So, we need a minimum of two equations to determine the solution. Since, only one equation is given here, we use the help of options.
