Answer:
B.
Step-by-step explanation: it is A. not B.
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."

Step-by-step explanation:
<h2>Hope my answer helps you hehe (/^▽^)/</h2>
I'll do the first one to get you started
The equation y = x^2+16x+64 is the same as y = 1x^2+16x+64
Compare that to y = ax^2+bx+c and we see that
a = 1
b = 16
c = 64
Use the values of 'a' and b to get the value of h as shown below
h = -b/(2a)
h = -16/(2*1)
h = -8
This is the x coordinate of the vertex.
Plug this x value into the original equation to find the corresponding y value of the vertex.
y = x^2+16x+64
y = (-8)^2 + 16(-8) + 64
y = 0
Since the y coordinate of the vertex is 0, this means k = 0.
The vertex is (h,k) = (-8, 0)
---------------------
So we found that a = 1, h = -8 and k = 0
Therefore,
f(x) = a(x-h)^2 + k
f(x) = 1(x-(-8))^2 + 0
f(x) = (x+8)^2
is the vertex form
---------------------
<h3>Final answer to problem 1 is f(x) = (x+8)^2 </h3>
<span>Number of values = 5 (There are 5 values given)
Mean = (82 + 44 + 67 + 52 + 120)/5 = 73
Variance = (1/5) [(82-73)^2 + (44-73)^2 + (67-73)^2 + (52-73)^2 + (120-73)^2] = 721.6
Standard deviation = sqrt (721.6) = 26.86</span>
