Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that

We have the a² and the b² in the equation
, and we <em>almost </em>have a 2ab in the equation
. To get that 2ab, we can simply double both sides of the first equation to get
. From there, we'll add the first two equations together, giving us the summed equation

And since
, we can equivalently say that

Using proportions, it is found that the statement that Tiffany would expect the spinner to land on a color section beginning with the letter "B" roughly 48 times is True.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, out of 8 sections, 4(Blue, Brown, Bronze and Black) begin with letter "B". We want to find the equivalent amount out of 98 trials. Hence, the <em>rule of three </em>is:
8 trials - 4 start with "B".
96 trials - n start with "B".
Applying cross multiplication:
8n = 4 x 96
n = 0.5 x 96
n = 48.
Hence, the statement is True.

(Pretend you're multiplying 15×20)
1. Start at 0 (obviously)
2. Go 20 numbers to the left and stop (if you're drawing or writing on the number line, make a line vertically to show that's where you stopped for the first 20
3. Do this 14 more times and keep on going to the right
B the answer is B
To create a survey you need a common entity linked to a unique feature
With B…he is able to create a table,draw a graph ,a pie chart and do so
Answer:
m = -10 + 5p
Step-by-step explanation:
5p − m = 10
subtract 5p from both sides:
5p − m - 5p = 10 - 5p
simplifiy:
-m = 10 - 5p
divide -1 to both sides
m = -10 + 5p
m = -10 + 5p
