6 0

Answer: 1/6 + 2/3 = ?

Step-by-step explanation and answer: To add fractions, you must have commen denomionators, so what is the least commen multiple of 6 and 3? You should say 6 because they are the lowest number that are equal, and the same. You should have 1/6 + 4/6=? You do not add the denomionators, they are still the number 6. But you add the numerators, so 4+1=5, so your answer is 5/6.

Answer:

B.The data are quantitative because they consist of they consist of counts or measurements.

Step-by-step explanation:

Qualitative data are those data which does not include any number. The data which has characteristic is known as Qualitative data.

Quantitative data are those data which include numbers.

Since the data of shoe sizes include numerical value. Thus it is Quantitative Data.

A student wants to survey the sophomore class of 200 students about whether the school should require uniforms. A random sample

kirill [66]

Answer:

Option D

Step-by-step explanation:

Complete question

A student wants to survey the sophomore class of 200 students about whether the school should require uniforms. A random sample of 18 sophomores is surveyed and asked whether they support the school adopting uniforms, and three students said yes. The student wants to construct a 95% confidence interval for the proportion of sophomores who favor the adoption of uniforms. Are the conditions for inference met?

Yes, the conditions for inference are met.
No, the 10% condition is not met.
No, the randomness condition is not met.
No, the Large Counts Condition is not met.

Solution

10 % of population size of 200 is 20. The sample of 18 is smaller than the 10 % of sample size of 200. As per the 10% rule, the size of sample must be less than 10% of the total size of population. This indicate that the sample is random but its size is less that 30. However, it should be greater that 30. Hence, the large count condition is not met.

Hence, option D is the correct choice of answer

Find the hcf of 15a²b² and -24ab | plzzz solve

tino4ka555 [31]

Answer:

$\large \boxed{\sf \ \ \ 3\cdot a \cdot b \ \ \ }$

Step-by-step explanation:

Hello,

First of all, let's find the factors of these two numbers and I will put <u>in boxes the common factors.</u>

$15a^2b^2=\boxed{3}\cdot 5\cdot \boxed{a} \cdot a \cdot \boxed{b} \cdot b \\ \\ \\-24ab=(-1)\cdot 2 \cdot \boxed{3} \cdot 4 \cdot \boxed{a} \cdot \boxed{b}$

The Highest Common Factor (HCF) is found by finding all common factors and selecting the largest one. So, in this case, it gives

$\large \boxed{\sf \ \ \ 3\cdot a \cdot b \ \ \ }$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
