Answers
The function that represents the values in the given table is; f(x) = log (1/x ), x ≠ 0
How to work with a Functional Model?From the attached table, we see that;
If x = 1/10, then f(x) = 1
From logarithm rule;
log(10) = 1
log(100) = 2
For the function f(x) = log (1/x), we have;
when;
x = 1/10, we have;
f(x) = log (1/(1/10)) = log (10) = 1
If x = 1/100, then;
f(x) = log (1/(1/100)) = log (100) = 2
Thus, the final answer is;
f(x) = log (1/x ), x ≠ 0

Answers
Answer:
D.
Explanation:
Put simply, a Computer Adaptive Test (sometimes referred to as personalised assessment) is a test which adapts to the candidate's ability in real-time by selecting different questions from the bank in order to provide a more accurate measure of their ability level on a common scale.
A test that adjusts the difficulty of the questions based on the student's answers to previous questions. The correct option is D.
What is adaptive test?An adaptive test is one that adjusts the difficulty level of the questions based on the student's performance on previous questions.
In other words, if a student correctly answers a question, the next one will be slightly more difficult. If a student incorrectly answers a question, the next question will be slightly easier.
Adaptive tests are used in a wide range of situations, including educational testing and computer-based assessments.
Adaptive testing has the advantage of providing a more accurate and efficient assessment of a student's knowledge and abilities.
The test can quickly determine the student's level of proficiency and provide a more precise measurement of their skills by adjusting the difficulty level of the questions.
Thus, the correct option is D.

A balloon takes 1 minute to rise 60 feet in the air. each minute after that, the balloon rises 40% as far as it did the previous minute. which equation represents the total distance, d, in feet that the balloon rises in 6 minutes?
Answers
The equation represents the total distance, d, in feet that the balloon rises in 6 minutes [tex]d=\frac{60(1-0.4^6)}{1-0.4}[/tex].
Given that a balloon takes 1 min to rise 60 feet in the air each min after that it rises 40% as far as the previous minute
So it second minute it rises 40% x 60 feet (60 x 0.4)= 24 feet in 3rd minute it rises 40% x 24 feet = (24x0.4) = (60x0.42) feet
So in n-th minute it rises (60 x [tex]0.4^{n-1}[/tex]) feet
So total height d in n- minutes will be
d = 60 + (60 × 0.4) + (60 × 0.4²) + ... + (60 x 0.4"-1)
= 60[1 + 0.4 + 0.4² + ... + 0.4" 1]
[tex]=60 \times \frac{1-0.4^n}{1-0.4}[/tex]
here n=6
So it will rise to
[tex]d=\frac{60(1-0.4^6)}{1-0.4}[/tex]

Triangle PQR has right angle Q. If sin R = 4/5
what is the value of tan P?
Answers
By applying Pythagorean' theorem, the value of tanP is equal to 3/4.
How to determine the value of tan P?Since triangle PQR has right-angle Q and sinR = 4/5, we have:
sinR = Opp/hyp = 4/5
tanP = Opp/Adj = QR/4
Next, we would determine the length of QR by applying Pythagorean' theorem:
PR² = QR² + PQ²
5² = QR² + 4²
25 = QR² + 16
QR² = 25 - 18
QR = √9
QR = 3 units.
For the value of tanP, we have:
tanP = 3/4.

The number of six samples that could belong to the same population is equivalent to six.
Option A is the correct answer.
What is the standard deviation?The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.
The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.
Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.
