Answer:
Step-by-step explanation:
A) License plates are made using 3 letters followed by 3 digits
If repitition is allowed we have
number of plates =
Option B
Out of 10 members 6 can be selected in
10C6 =210
Option B
3 tax returns from 13 can be selected in
13C3 =286
Option D
Prob of taking 3 cherry from 11 cherries is
6C3/11C3=20/165=0.1212
Option B
First integer = x
Second integer = x + 2
Third integer = x + 4
Since four times the first integer equals six more than the product of two and the third integer.
4x = 6 + 2(x + 4)
4x = 6 + 2x + 8
2x = 14
x = 7.
Hence,
First integer = x = 7
Second integer = x + 2 = 7 + 2 = 9
Third integer = x + 4 = 7 + 4 = 11.
hope this helps
You can obtain the graph of the function y=-2sinx-1 from the graph of the function y=sinx making such transformations:
1. <span>the multiplication by -2 increases y value twice and then symmetrically reflects the graph y=2sinx about the x-axis;</span>
2. adding -1 to the <span>y=-2sinx you translate the graph 1 unit down.
</span><span>
</span><span>On the added picture black line is a graph of y=sinx and red line is a graph of y=-2sinx-1.</span>
Check:
1. When x=0, y=-2sin0-1=-1;
2. When
, then
.
