To determine The probability of both of these occurring, you would multiply the probability of each together. So, there is a 1/7 chance of the first salesman getting the right key, and 1/6 chance of the second salesman getting the right key. 1/7 x 1/6= 1/42 chance of both occurring.
Step-by-step explanation:
-3x - 10 > 14
-3x > 24 (add 10 to both sides)
x < -8 (divide by -3, flip inequality sign)
The missing step is -3x > 24.
Answer:
I can't see the picture but I can tell you this. To find the area of a triangle, you simply have to multiply the base and the height, and then divide by 2.
1/2(B*H)=a
Answer:
c
Step-by-step explanation:
c
Answer:
k = -11
Step-by-step explanation:
Let 
And x+2 is a factor of p(x)
Let x+2 = 0 => x = -2
Putting in p(x)
=> p(-2) = 
<u><em>By remainder theorem, Remainder will be zero</em></u>
=> 0 = -8-6(4)-2k+10
=> 0 = -8-24+10-2k
=> 0 = -22-2k
=> -2k = 22
Dividing both sides by -2
=> k = -11
