Answer:
11/23 or 0.478
Step-by-step explanation:
1. Find the probability of selecting 2 red chips:
11/23 * 10/22 = 5/23
2. Find the probability of selecting 2 blue chips:
12/23 * 11/22 = 6/23
3. Add the two probabilities:
5/23 + 6/23 = 11/23 = 0.478 (rounded to 3 decimal places)

Answer:
Matrix B should be subtracted from Matrix A.
Step-by-step explanation:
Scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing .
In this case the ladybug is 8 mm long but drawing length is 2 cm.
Let’s convert both into the same units
2 cm -20 mm
Original - 8 mm
Painting -20mm
X - scale factor
20 = X * 8
X = 20/8 = 2.5
The ladybug has been multiplied/ enlarged by a scale factor of 2.5 to draw the painting

Answer:
There are 2/3 of the content as servings in 4 bags
Step-by-step explanation:
In this question, we are asked to calculate the amount of servings in 4 bags
From the question, we can see that the amount of servings in a single bag is 1/6 of the bag.
Now the number of servings in 4 bags will be mathematically equal to ; 1/6 + 1/6 + 1/6 + 1/6 = 4 * 1/6 = 4/6 = 2/3
This means that in 4 bags, 2/3 of the total content is the servings
