Answer:

5/9

Step-by-step explanation:

Total number of bikes = 18
Bikes with gears S = 9
Bikes with suspension S = 11
Bikes with both GS = 5

<u>From the information above we have:</u>

Bikes with gears only = 9 - 5 = 4
Bikes with suspension only = 11 - 5 = 6

<u>Sum of the above two gives us the number of bikes with suspension or gears:</u>

4 + 6 = 10

<u>Probability of selected bike be G or S is:</u>

P(G or S) = 10/18 = 5/9

Is the ordered pair a solution of y ≥ 2x − 5? a. (3, 1) b. (1, −4)

Deffense [45]

Answer:

a. Yes

b. No

Step-by-step explanation:

To find if an ordered pair is a solution to the inequality, substitute its x and y values for the x and y in the inequality and solve. If the equation is true, then it is a solution. If it is not, then it is not a solution.

1) First, substitute the x and y values of (3, 1) into the inequality. So, substitute 3 for x and 1 for y:

$1 \geq 2(3)-5\\1\geq 6-5\\1\geq 1$

1 is greater than or equal to 1, so (3,1) is a solution.

2) Second, do the same with the point (1, -4). Substitute 1 for x and -4 for y:

$-4\geq 2(1)-5\\\\-4\geq 2-5\\-4\geq -3$

However, -4 is not greater than or equal to -3, thus (1, -4) is not a solution.

What is the difference between multiplying a whole number by a decimal and multiplying two whole numbers

anastassius [24]

Two whole numbers will end up like this: 8x8=64,but multiplying a whole and a decimal will end up like this 8x8.1=64.1
or 8x8=8 to the second power.
this should be sufficient information.

The square root of -1 is i. So you can simplify it to 7(sqrt)-1, which becomes 7i.
