A linear correlation scatterplot is also a direct proportionality. True or False

Mathematics
1 answer:
Blizzard [7]3 years ago
4 0

Answer: False

Step-by-step explanation: A linear correlation scatter plot is one which is aimed at establishing a graphical view of the relationship between two quantitative variables. A linear correlation scatter plot could either be positive which is depicted by a positive gradient which infers direct proportionality, this means an increase in variable A results in increase in variable B while a decrease in variable A results in decrease in variable B. Similarly, it could also exhibit a negative gradient which infers a inverse proportionality meaning a decrease in one variable leads to increase of the other and vice-versa. Hence, a linear scatterplot does not only exhibit direct proportionality.

The surface area of a pyramid is 327 square meters. what is the surface area of a similar pyramid that is smaller by a scale fac
N76 [4]

Answer:

\boxed{\text{144.33 m}^{2}}

Step-by-step explanation:

The scale factor (C) is the ratio of corresponding parts of the two pyramids.  

The ratio of the areas is the square of the scale factor.

\dfrac{A_{1}}{ A_{2}} = C^{2}\\\\\dfrac{\text{327 m}^{2}}{A_{2}} = \left (\dfrac{1}{\frac{2}{3}}\right)^{2}\\\\ \dfrac{\text{327 m}^{2}}{A_{2}}= \dfrac{9}{4}\\\\\text{1308 m}^{2}= 9A_{2}\\\\A_{2} = \text{145.33 m}^{2}\\\text{The surface area of the smaller pyramid is \boxed{\text{145.33 m}^{2}}}

Which equations can be used to solve for acceleration? Select four options.
sweet [91]

Equations for the acceleration: a=\frac{v-u}{t}, v=u+at

Step-by-step explanation:

The acceleration of a body is the rate of change in velocity of the body; it is given by

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time taken  for the velocity to change from u to v

The equation can be also written as

v=u+at

Therefore, these two equations can be used to find the acceleration.

Which graph represents the solution?​
marusya05 [52]

Answer:

A

Step-by-step explanation:

Given the inequality :

v + 4 > 2 and 8v - 20 < 36

v + 4 > 2

v > 2 - 4

V > - 2

8v - 20 < 36

8v < 36 + 20

8v < 56

v < 56/8

v < 7

Hence,

v > - 2 and v < 7

-2 < v < 7
