Answer:
x = 2,66
Step-by-step explanation:
4x + 2x = 6 + 10
6x = 16
6x % 6 = 16 % 6
x = 2 ,66
Answer:
Option d is right
Step-by-step explanation:
We know that a linear correlation is a measure of association between two variables dependent and independent variable. r always lies between -1 and 1 both inclusive. If r is nearer to 0 weak correlation and if |r| is near to 1 there is a stronger correlation.
Positive sign of r implies positive association and negative r implies negative association.
Hence out of the four options given about correlation we have
Option a is right because removal of outliers confirm accurate correlation
Option B is right because only if linear pattern is visible, correlation will be right
Option C is right because only for numerical data r can be calculated
Option d is wrong because correlation lies always between -1 and 1 both inclusive.
16 tiles will fit end to end on a 4 foot wall.
In unitary method we will learn how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.
When we go to the market to buy any article, we ask the shopkeeper to tell the price of the article. This is called unit price. We calculate the price of number of articles, we want to buy, with the help of this unit price. Sometimes, we calculate unit price when the price of a multiple is given.
1 tile in 1/4 foot
So in 4 foot wall the number of tiles = 4/(1/4) = 16 tiles.
Thus 16 tiles will fit end to end on a 4 foot wall.
