The true statement is -2>-3
Step-by-step explanation:
The given statement included inequality and comparison symbols. The numbers involved are negative integers.
As the number increases its value decreases which means that -1 will be greater than -2 and so on
Given statement will be discussed one by one
-2 <-3
-2 comes before -3 so the statement is true as -2 will be greater than -3.
-2>-3
The statement is true because -2 is greater than -3
The true statement is -2>-3

Answer:
99.7%
Step-by-step explanation:
Using the z score formula
z-score is z = (x-μ)/σ
where:
x = raw score
μ = population mean
σ = population standard deviation.
a) for x = raw score = 35
μ = population mean = 44
σ = population standard deviation =3
z = (35 - 44)/3
z = -9/3
z = -3
b) for x = raw score = 53
μ = population mean = 44
σ = population standard deviation =3
z = (53 - 44)/3
z = 9/3
z = 3
We would use the standard normal distribution table to find their probabilities
P(Z<=-3)=0.0013499
P(Z<=+3)=0.99865
So P(-3<=Z<=3)=0.99865 - 0.0013499 = 0.9973
Converting to percentage = 0.9973 × 100 = 99.73%
Therefore, the percentage of auto batteries of this brand that have a life of 35 to 53 months to one decimal place is 99.7%
