Answer:
Step-by-step explanation:
We can do this a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15
This trinomial factors into
y = (x - 5)(x + 3)
from which
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15
<em>Answer</em>
- x intercepts: (-3,0),(5,0)
- y intercept: (0,-15)
The graph is below.
False , Combining a coin toss and a roll of a die makes a simple event.
In statistics, what does a probability mean?
- The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is.
- P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.
- Mathematics' study of random events is known as probability, and there are four primary types of probability: axiomatic, classical, empirical, and subjective.
- Since probability is the same as possibility, you could say that it is the likelihood that a specific event will occur.

A true statement is "For data at the interval level, you CAN calculate meaningful differences between data entries."

103.13
Step-by-step explanation:
A=πr2
C=2πr
A=C2
4π=362
4·π≈103.1324
The table with greater proportionality is table 3.
<h3>What is constant proportionality?</h3>
The constant of proportionality is the ratio between two directly proportional quantities.
As, the constant proportionality is
k= y/x
For table 1,
k = 1/1 = 2/2 =1
For table 2,
k = 6/1= 12/2 = 2
For table 3,
k = 5/1 = 10/2 = 5
For table 4,
k = 4/1 = 8/2 = 4
Hence, table 3 is with greater proportionality.
