A) 1/2 bc half of the spinner is white
B) 1/2, 0.5
C) is the last one, the bottom one to be right
Answer:
f(x)= x^2 - 2, the one in red.
Step-by-step explanation:
To move a quadratic function up/down, you change the value at the very end of the formula.
So instead of f(x)= x^2 + 1, you would do f(x)= x^2 - 2, to move it down 3. This would be the one in red.
Answer:
AUB = {E1, E2, E4, E6, E7}
Step-by-step explanation:
Since we are to look for the union of the two sets, therefore we combine all the sample points that are contained in A and B without repeating any sample even if such sample occur in both sets. For example, E4 occurs in event A and B and as such will only be repeated once in the union of the two events.
AUB = {E1, E2, E4, E6, E7}
Note that the way you arrange does not matter as well.
I hope you find this solution useful?
Take first number as x
<span />second number is 3x
<span />third number = 3x+5
<span>
</span>
<span>
</span>
twice the third is 5 less than second, means second minus 2 times third is equal to five or 3x-2(3x+5)=5..........Answer is D
