I WILL MAKE YOUR ANSWER THE BRAINLIEST IF YOU KNOW IT IS RIGHT
Bad White [126]

Answer:

54π

Step-by-step explanation:

To find the volume of a cylinder, you multiply the area of the base times the height.

The formula for the area of a circle is πr², so the base is 9π units².

Multiplying that by the height (6 units) gives you 54π units³.

The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures students’ attitudes toward school and stud
sineoko [7]

Answer:

The conditions for carrying out a significance test are:

1. It must be a Random sampling

2. It should be a Normal distribution

3. It should be Independent

Step-by-step explanation:

SRS means simple random sample; it is a sampling technique in which individuals can be chosen from the population in such a way that every individual stands an equal chance to be selected as the sample.

The conditions needed or required to carry out a significance test of the teacher's suspicion are:

1. It must be a Random sampling

2. It should be a Normal distribution

3. It should be Independent

All of these conditions are met; the sampling is random as indicated by SRS, it is a normal distribution because one popular rule states that a sample size of at least 30 is enough and here we have a sample size of 45, it is independent because the sample size of 45 is less than 10% of the population

The logarithmic expression ln(√e/y^3) can be rewritten as
kvv77 [185]

Answer:

\dfrac{1 - 6 \ln y}{2}

Step-by-step explanation:

\ln \dfrac{\sqrt{e}}{y^3} =

= \ln \dfrac{e^\frac{1}{2}}{y^3}

= \ln e^\frac{1}{2} - \ln y^3

= \dfrac{1}{2} \ln e - 3 \ln y

= \dfrac{1}{2} - 3 \ln y

= \dfrac{1 - 6 \ln y}{2}

In what instance would you use the upside down U when doing interval notation
Jet001 [13]
The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.

The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).
