A square with a side length of 5 inches has a area of 25 in true or false

Find the product. (8 − 3i)(5 − 2i)

Delicious77 [7]

Answer:

34 - 31i

Step-by-step explanation:

first, distribute to get 40 - 16i - 15i + 6i^2. i^2 = -1 so 6(-1) is -6. simplify to get 34 -31i

1. Write an equation in point-slope form for the line through the given point with the given slope.

ElenaW [278]

Answer: y + 2 = $\frac{-1}{2}$ ( x - 4 )

Step-by-step explanation:

The equation of a line in point - slope form is given as ;

y - $y_{1}$ = m (x - $x_{1}$ )

$x_{1}$ = 4

$y_{1}$ = -2

m = $\frac{-1}{2}$

Substitute the values into the equation , we have

y - (-2) = $\frac{-1}{2}$ ( x - 4 )

y + 2 = $\frac{-1}{2}$ ( x - 4 )

Which could be written as :

y + 2 = y + 2 = $\frac{-1}{2}$ x + 2

A matched-pairs t-test is NOT an appropriate way to analyze data consisting of which of the following? Measurements of annual in

o-na [289]

Answer:

Step-by-step explanation:

A matched pair t test is one in which the set of data is divided into two sets of data and the test is done to test the difference between the pairs. Sometimes this is called paired t test.\

This is done normally where one group of sample or population can be paired with other group of sample /population.

Hence

A .Measurements of annual income for each twin for 100 randomly selected pairs of twins -- True

B. Measurements of annual income for both individuals in pairs formed by matching 100 people from State A and 100 people from State B based on level of education -- True

C. Measurements of annual income for both individuals in pairs formed by assigning 100 people to pairs at random -- True

D. Measurements of annual income recorded for both spouses of 100 randomly selected married couples --False here we cannot say paired as these people are not grouped under the same conditions.

What is the volume of a cylinder if ,

sergiy2304 [10]

38,016 cm³

<h3>Ⲋⲟⳑⳙⲧⳕⲟⲛ :</h3>

We are given that :

Height of cylinder = 21 cm

Radius of cylinder = 24 cm

Therefore, Volume :

➙ V = πr²h

➙ V = ( 22 / 7 ) × ( 24 )² × ( 21 )

➙ V = ( 22 / 7 ) × 576 × 21

➙ V = ( 22 × 576 × 21 ) / 7

➙ V = 266112 / 7

➙ V = 38016

‎ㅤ‎ㅤ ‎ㅤ‎ㅤ~Hence, the volume of given cylinder is 38,016 cm³.

<h3>⳨ⲟⲅⲙⳙⳑⲇ ⳙ⳽ⲉ∂ :</h3>

The volume of cylinder is it's density which tells us the amount by which it can be filled by any material or the the amount of material which can be immersed in it.

The Formula for volume of cylinder is given by :
