O A. -0.5•(-0.4) =
B. The expression is undefined
(Answer quickly)
To multiply numbers or expressions means that we calculate the product of the numbers or expressions. The value of [tex]-0.5 \times (-0.4)[/tex] is [tex]0.2[/tex]
Given that:
[tex]-0.5 \times (-0.4)[/tex]
Cancel out the negative signs
[tex]-0.5 \times (-0.4) = 0.5 \times (0.4)[/tex]
Using a calculator, we have:
[tex]-0.5 \times (-0.4) = 0.2[/tex]
Hence, the value of [tex]-0.5 \times (-0.4)[/tex] is [tex]0.2[/tex]

there are 45 students in a speech contest. Yesterday, 2/3 of them have their speeches. Today, 3/5 of the remaining students give their speeches. How many students still haven't given their speeches?
Answer:6 students remaining
Step-by-step explanation:Multiply 2/3 *45 which equals 30. If 30 students gave their speech on the first day there are 15 students remaining. Then multiply 3/5 * 15 which equals 9. If 9 of the 15 remaining students gave their speech than 15-9= 6 students remaining.

Find the lest number which is exactly divisible by 36 & 90 Maths
Answer:
180Step-by-step explanation:
You need to find the HCF of 36 and 90.
Prime factors of each:
36 = 2*2*3*390 = 2*3*3*5HCF includes all prime factors of both numbers:
HCF(36, 90) = 2*2*3*3*5 = 180To find the least number,
Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.
→ 36 = 2 × 2 × 3 × 3
→ 90 = 2 × 3 × 3 × 5
Then the required HCF will be,
→ 2 × 2 × 3 × 3 × 5
→ 180 (HCF)
Thus, 180 is the least number which is exactly divisible by 36 and 90.
Part B If Ivy conducted her survey of 25
students on a volunteer basis, are the
results representative of the school?
Why or why not?
Answer:
Step-by-step explanation:
No, the results are not necessarily representative of the school as a whole.
What is the random survey?A random survey is a research technique that is used to gather information from a sample of people or things in a population. The results of a random survey are more likely to be representative of the population as a whole since every member of the population has an equal chance of being chosen to take part in the research.
Given:
Ivy randomly surveys students in her school to learn more about mobile phone password use.
Of 25 respondents, 14 use a password.
If the survey was conducted on a volunteer basis, it is possible that the respondents who chose to participate may have different characteristics or behaviors than those who did not participate.
This could lead to a biased sample that does not accurately represent the entire school population.
Additionally, even if the sample is representative of the school population, a sample size of 25 is relatively small, which can increase the margin of error and make it more difficult to draw accurate conclusions.
Therefore, it is important to consider the limitations of the survey method and sample size when interpreting the results.

Answer:
All real numbers
Step-by-step explanation:
4(x+1) = 4x+4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions
Solution:
Let's find the required solution,
→ 4(x + 1) = 4x + 4
→ 4x + 4 = 4x + 4
→ (4x - 4x) + 4 = 4
→ 4 = 4
→ LHS = RHS
The answer is all real numbers.

If the composition of two functions is:
1/x−3
What would be the domain restriction? Describe how you found that answer.
9514 1404 393
Answer:
x ≠ 3
Step-by-step explanation:
In any case, the domain is restricted to values of the variable for which the function is defined. The value 1/0 is not defined, so the variable cannot allow the denominator to be zero. The denominator x-3 will be zero for x=3, so that value of the variable cannot be in the domain.
The domain is all real numbers except x=3.

Additional comments
It is useful to become familiar with the domains of different functions. As we saw above, the reciprocal of 0 is undefined. The square root of a negative number is undefined. The log of a non-positive number is undefined. Trig functions are defined everywhere, but their inverse functions are not. Polynomial functions are defined everywhere, but ratios of polynomials have the same restriction on denominators that we see above.

An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
T lies on both FH and GJ.
Now by the given figure;

Which of the following best defines qualitative observation?
Question 5 options:
Data that can be observed using our sense of sight only
Data that can be observed with our five senses
Data that must be measured
Data that must be quantified
Answer:
""Data that can be observed with our five senses """is right option..
Step-by-step explanation:
A qualitative observation involves the use of five sensory organs, sight, smell, taste, touch, and hearing, and their function to examine the attributes. Being subjective in nature, it focuses on the characteristics and qualities of the variables rather than the numerical value.
Use the equation below to complete the statement. 5 . 26 − □ = 1 . 38 The value 3.12 makes the equation.
true or false?
the aswer is...false
It is false that 5 . 26 − □ = 1 . 38 The value 3.12 makes the equation. To check if the value 3.12 makes the equation true or false, we can substitute it into the equation and see if both sides are equal.
Given equation:
5.26 − □ = 1.38
Substitute □ with 3.12:
5.26 − 3.12 = 1.38
Now, calculate the left-hand side:
5.26 - 3.12 = 2.14
The equation becomes:
2.14 = 1.38
Since 2.14 is not equal to 1.38, the equation is false when □ is replaced with 3.12.
Therefore, the value 3.12 does not make the equation true.
