Answer:
Probability of picking yellow stones from the bag is 0.3.
Step-by-step explanation:
Given:
Number of red stone in bag = 5
Number of green stone in bag = 2
Number of blue stone in bag = 3
Number of yellow stone in bag = 6
Number of purple stone in bag = 4
We need to find the probability of choosing yellow stone from the bag.
Solution:
First we will find the Total number of stones in the bag.
Total number of stones in the bag is equal to sum of Number of red stone in bag ,Number of green stone in bag, Number of blue stone in bag, Number of yellow stone in bag and Number of purple stone in bag.
framing in equation form we get;
Total number of stones in the bag =
Now Probability of picking yellow stones from the bag can be calculated by dividing Number of yellow stone in bag by Total number of stones in the bag.
framing in equation form we get;
Hence Probability of picking yellow stones from the bag is 0.3.
Complete Question:
Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future?
s(t)•h(t)= (3x-4)(2x-8)
= 6x² - 24x -8x - 32
= 6x² - 32x - 32
Answer:
Jamie made a mistake in his second line (6x² - 24x -8x - 32), by wrongly multiplying the operation signs. The last term should be +32, not -32.
Advice: Jamie should take note of the rule that applies when multiplying signs.
Step-by-step Explanation::
To find out where exactly Jamie made mistake, let's find the product of the given functions, step by step:
s(t)•h(t)= (3x-4)(2x-8)
Using distributive property, do the following:
(this is where Jamie made mistake. -4 * -8 = +32. NOT -32.)
Add like terms
Jamie made a mistake in multiplying negative × negative. The last term in "6x² - 24x -8x - 32", should be +32. Negative × negative = +.
Therefore, it is advisable for Jamie to always take note of the rule that applies when multiplying signs.
