300 30 3 0.3
part a answer is 0.03 0.003
part b
what is the relationship between the terms in the pattern?
Answer:
Part a) the next two numbers of the sequence is 0.03, 0.003
part b)
We get each successive terms, we get previous term divided by 10.
2nd term = 1st term ÷ 10
3rd term = 2nd term ÷ 10
4th term = 3rd term ÷ 10
Step-by-step explanation:
The given number are 300, 30, 3, 0.3
You can see that the previous number divided by 10 to get the next number.
So the next two numbers are
0.3 ÷ 10 = 0.03
0.03 ÷10 = 0.003
Part a) the next two numbers of the sequence is 0.03, 0.003
Part b.
We get each successive terms, we get previous term divided by 10.
2nd term = 1st term ÷ 10
3rd term = 2nd term ÷ 10
4th term = 3rd term ÷ 10

Explain how we use a tree diagram to determine the probability of an events
Tree diagrams are a helpful tool for calcuating probabilities when there are several independent events involved. They get their name because these types of diagrams resemble the shape of a tree. The branches of a tree split off from one another, which then in turn have smaller branches. Just like a tree, tree diagrams branch out and can become quite intricate.

There are 44 books per shelf and there are 8 shelves 1/4 of these books are novels.How many novels will there be??
There will be 88 novels among the total of 352 books.
To find the number of novels, we can use the information that 1/4 of the books are novels.
First, we calculate the total number of books:
Total number of books = 44 books/shelf * 8 shelves
= 352 books
Then, we can find the number of novels:
Number of novels = 1/4 * 352 books
= 88 books
Therefore, there will be 88 novels.

From a group of 8 people, you randomly select 2 of them. What is the probability that they are the 2 oldest people in the group?
The probability of randomly selecting the 2 oldest people from the group of 8 is approximately 0.0357 or 3.57%.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The total number of possible ways to select 2 people from a group of 8 is given by the combination formula:
C(8,2) = 8! / (2! x 6!) = 28
This means that there are 28 different pairs of people that can be selected from the group of 8.
To calculate the probability that the 2 oldest people are selected, we need to first determine how many ways there are to select these 2 people.
Since the order in which we select the people does not matter, we can simply choose any 2 people from the group of 8 in order to select the 2 oldest people.
There are C(8,2) = 28 ways to select any 2 people, and since there is only 1 pair that consists of the 2 oldest people, the number of ways to select the 2 oldest people is 1.
Now,
The probability of selecting the 2 oldest people is:
1/28 = 0.0357
Thus,
The probability of randomly selecting the 2 oldest people from the group of 8 is approximately 0.0357 or 3.57%.

Final answer:
To find the probability of selecting the two oldest people from a group of 8, we calculate the number of ways to choose 2 people from 8 (28 ways) and understand that there is only 1 way to choose the two oldest. Thus, the probability is 1/28.
Explanation:
The question asks about the probability of selecting the two oldest people from a group of 8. To solve this, we can use the concept of combinations. There is only one way to pick the two oldest people. However, the total number of ways to pick 2 people out of 8 is calculated using combinations, which can be represented as 8 choose 2 or 8C2. The formula for combinations is nCk = n! / (k!(n-k)!), where n is the total number of items, and k is the number of items to choose.
Applying this formula, the total number of ways to choose 2 people from 8 is :
8C2 = 8! / (2!(8-2)!) = 28
Therefore, the probability that the two people selected are the oldest is :
Probability = 1 / 28
What graph represents the inequality y≥2−2x?
The graph for the inequality y ≥ 2 - 2x is a downward sloping line with a y-intercept of 2. The area above this line, including the line itself, is shaded to denote the solutions for the inequality.
Explanation:The equation y ≥ 2 - 2x is a linear inequality with a slope of -2 and a y-intercept of 2. It is represented graphically as a straight line where y is equal to or larger than 2 - 2x. As the coefficient of x is negative, the line will slope downwards towards the right based on the rule mentioned in Figure 12.4 (c).
In a two-dimensional (x-y) graph, x represents the independent variable while y is the dependent variable. Thus, for every increase of 1 unit on the x-axis (horizontally), the value of y decreases by 2 units (vertically) due to the slope of -2.
Since y is greater than or equal to 2 - 2x, the area above the line (including the line itself as it's a 'greater than or equal to' inequality) will be shaded when the inequality is graphed. This shading means that any point within this area is a solution to the inequality.

Jude incorrectly squared the common base (1/2) when she should have added the exponents. The correct simplification of (1/2) ² × 1/2 × (1/2) ³ is (1/2) ⁵, which equals 1/32.
Jude made a common mistake while simplifying the expression (1/2) ² × 1/2 × (1/2) ³.
Instead of combining the exponents correctly, Jude incorrectly assumed that raising the power of a power would simply entail squaring (1/8), thus ending up with (1/8) ⁶ which equates to 1/262,144.
However, the correct method to simplify the expression involves adding the exponents when multiplying the same base number.
The correct simplification would be (1/2) ⁵ because we have (1/2) ² (twice), then multiplied by 1/2 (once), and then by (1/2) ³ (thrice), so the sum of the exponents is 2+1+3=6.
Therefore, (1/2)⁵ equals 1/32.
Following the rules for powers and exponents ensures that we arrive at the correct mathematical solution.

Enter your answer as a decimal
Answer:
The low temperature for the night was of -22.7 °F.
Step-by-step explanation:
As the high temperature during the day was 15.7 degrees, but it fell 38.4 degrees in the night, in order to know which was that temperature we have to do the following calculation:
15.7 - 38.4: X (Temperature for the night)
-22.7: X
The low temperature for the night was of -22.7 °F.

Simon wanted to find the equation of a line that passes through (–6, 5) and is perpendicular to the graph of 3x + 2y = –11. His work is shown below.
1. 3x + 2y = –11 written in slope-intercept form is y = x , so the slope is .
2. The slope of the perpendicular line is .
3. Substitute the point and the new slope into point-slope form to get y – 5 = (x – (–6)).
4. Simplifying, the line is y – 5 = (x + 6)
"3x + 2y = –11 written in slope-intercept form is y = x." Not so.
To find the slope of this line, solve for y:
2y = -3x - 11 => y = (-3/2)x - 11/2. The slope of the given line is -3/2. The
graph of the new (perpendicular) line will then be the negative reciprocal of -3/2, or +2/3.
Now use the point-slope formula for the equation of a straight line to determine the equation of this new (perpendicular) line thru (-6,5):
y-5 = (2/3)(x+6) (answer)
To find the equation of a line perpendicular to a given line, we need to find the negative reciprocal of the slope of the given line. Using the point-slope form, we can substitute the point and the new slope to get the equation of the perpendicular line.
Explanation:1. To write the given equation in slope-intercept form, we need to solve for y. Rearranging the equation, we have 2y = -3x - 11, y = (-3/2)x - 11/2. Therefore, the slope of the given line is -3/2.
2. The slope of a line perpendicular to another line is the negative reciprocal of the slope of the given line. So, the slope of the perpendicular line is 2/3.
3. Using the point-slope form, we substitute the point (-6, 5) and the new slope (2/3) into the equation y - y1 = m(x - x1), where x1 and y1 are the coordinates of the given point. Plugging in the values, we get y - 5 = (2/3)(x + 6).
4. Simplifying the equation, we can distribute 2/3 to x and 6, which gives us y - 5 = (2/3)x + 4. Adding 5 to both sides, the final equation of the line passing through (-6, 5) and perpendicular to 3x + 2y = -11 is y = (2/3)x + 9.
