<span>it all looks confusing when we try to juggle with all those numbers in the head. The problem can be solved systematically by constructing a contingency table.
</span>role/gender B G total
speaking...... 4 4 8
<span> silent............ 4 8 12
total............. 8 12 20
</span>Probability of a child having a speaking part is therefore
(4+4)/20=8/20=2/5
a. 2/5
The baby blue whale weighs 30 pounds, since 120 divided by 40 is 30.
Just multiply out the given expression, combine like terms and arrange them in descending order by powers of x.
<span>2x(3x-2)+5(3x-2) => 6x^2 - 4x + 15x - 10
Combining like terms results in 6x^2 + 11x - 10 (answer)</span>
Answer:
There is a horizontal shift.
Step-by-step explanation:
Replacing x in a function formula with x - 8 moves the graph 8 units to the <u>right</u>.
In the attached image, y = sin(x) is light green, y = sin(x - 8) is dark green, and the arrows show how points on sin(x) get moved 8 units to the right.
