Answer:
The range of F(x) = logbx is the set of all positive real numbers is TRUE
Step-by-step explanation:
Given:
A function which logarithmic i.e F(x)=logbX=logx/logb with base 10
To Find;
Range belongs to All set are positive real numbers.
Solution:
The domain is function for which all set of inputs are defined and range for function is that set of all output that functions takes.
So Simple logarithmic function y=logbX is

So The functions has domain of all real values and range set of all real number.
In general the function F(x) = logbx where X>0 and b≠1 is continuous and one to one function.
logarithmic function is not defined for negative numbers or for zero.
And Also function approaches y-axis as x-tends to infinity but never touches the it.
Hence the Given statement is true

Standardized tests: In a particular year, the mean score on the ACT test was 19.3 and the standard deviation was 5.3. The mean score on the SAT mathematics test was 532 and the standard deviation was 128. The distributions of both scores were approximately bell-shaped. Round the answers to at least two decimal places. Part: 0/4 Part 1 of 4 (a) Find the z-score for an ACT score of 26. The Z-score for an ACT score of 26 is
Answer:
1.26
Step-by-step explanation:
Given that:
For ACT:
Mean score, m = 19.3
Standard deviation, s = 5.3
Zscore for ACT score of 26;
Using the Zscore formula :
(x - mean) / standard deviation
x = 26
Zscore :
(26 - 19.3) / 5.3
= 6.7 / 5.3
= 1.2641509
= 1.26
