Answer:

Q1 A Scatter plot. Q2

Step-by-step explanation:

Q1. We have a data set containing values of car and age group, if we plot value of the car on y-axis and the age on x, it is logical that two different age groups can own a care with same value, so we can have two values on x corresponding to one value on the y-axis, if we can use scatter plot to visually depict this data.

Consider a cylinder with radius 4 cm and a height of 12 cm. Describe how to calculate the volume of the given cylinder and what
Talja [164]

\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ -----\\ r=\stackrel{cm}{4}\\ h=\stackrel{cm}{12} \end{cases}\implies V=\pi (4)^2(12)\implies V=192\pi~cm^3


192π is about 603.19 cm³.


well, it means if you grab a hmmmm cube, say that is 1cm x 1cm x 1cm, namely a 1cm tall, 1cm wide and 1cm long, whose value is 1cm³, you can fit 603.19 of those in that cylinder.

At a farmers market, a package of pears weighs 3lb and cost $9. Bananas are priced at 4lb per dollar. Use rates to explain witch
LiRa [457]

Answer:

The pears are more expensive per pound

Step-by-step explanation:

Find the cost per pound of the pears and bananas by dividing the cost by the number of pounds:

Pears:

9/3

= 3 ($3 per pound of pears)

Bananas:

1/4

= 0.25 ($0.25 per pound of bananas)

Since 3 is larger than 0.25, this means the pears are more expensive per pound.

6k²+16k=0<br> x²-5x= 0<br> ANSWer these noeww!
pentagon [3]

Answer:

1) k = (-8)/5

2) x = 5

Step-by-step explanation:

1)

6 {k}^{2}  + 16k = 0

=  > 2k(3k + 8) = 0

=  > 3k + 8 =  \frac{0}{2k}  = 0

=  > 3k =  - 8

=  > k =  \frac{ - 8}{3}

2)

{x}^{2}   - 5x = 0

=  > x(x - 5) = 0

=  > x - 5 =  \frac{0}{x}  = 0

=  > x = 5
