Salvatore is making party favors for his birthday party. He has 96 pencils and 80 boxes of raisins. Find the GCF of 96 and 80 to
2 answers:
Answer:
GCF is 16, and 6 pencil boxes, and 6 boxes of raisins.
Step-by-step explanation:
Since, we know the factors of 96 and 80 as:
96 is: 2 x 2 x 2 x 2 x 2 x 3.
85 is: 2 x 2 x 2 x 2 x 5.
So, the factors in common are:
85 and 96: 2 x 2 x 2 x 2
therefore, HCF is:
2 x 2 x 2 x 2 = 16
For pencil boxes,
For raisins boxes,

The initial value of the graph is where . Thus, in this case, the initial value is 12.
The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:
and
are points on the graph
Let's use two points from the chart to find the slope:
In this case, the rate of change of the graph is 9.
Answer:
a) 0.35
b) 420 drawing pins
Step-by-step explanation:
a) The question relates to the relative frequency of the pins pointing up which is found by the formula as follows;
The total number of pins land 'point up' = 3 + 5 + 6 + 2 + 4 + 7 + 3 + 3 + 4 + 5
The total number of pins land 'point up' = 42 successful trials
Total number of trials = 12 × 10 = 120 trials
Due to the large number of trials, the relative frequency ≈ Probability and the probability that a single pin will land point up = 7/20 = 0.35
b) Given that the number of trials now = 12 × 100 = 1200, we have;
The expected number of drawing pins in total that would land point up = 0.35×1200 = 420 pins.
