Answer:
x=-9/2+sqr2 or x=-9/2-sqr2
Step-by-step explanation:
So my title in Brainly isn't Expert and people probably don't call me that in real life, but we have been studying this in my math class.
Domain is the extent of X values while range is Y. The shown quadratic equation continues to the left an infinite amount as well as to the right. The answer is all real numbers since it continues to infinity both directions.
The probability of getting a reading between 1.50 and 2.25 is; 0.00546
<h3>How to find the probability from z-score?</h3>
We are given the following information in the question:
Mean; μ = 0 °C
Standard Deviation; σ = 1 °C
We are given that the distribution of thermometer readings is a bell shaped distribution that is a normal distribution.
Formula for z-score is;
z = (x' - μ)/σ
P(Between 1.50 degrees and 2.25 degrees) is expressed as;
P(1.5 ≤ x ≤ 2.25)
= P((1.5 - 0)/1 ≤ z ≤ (2.25 - 0)/1))
= P(z ≤ 2.25) - P(z < 1.5)
= 0.0546 = 5.46%
The graph that correctly describes this is the first graph
