13 is prime so the GCF is 1.
The LCM: 13*15/1=195

o-na [289]

Answer:48

Step-by-step explanation:

Given

Amar wants 12 tablespoons of sugar in water.

Amar has teaspoon whose four times is equivalent to 1 tablespoon

i.e. $4\ \text{teaspoon}\equiv 1\ \text{tablespoon}$

therefore

$12 tablespoon is 4\times 12$

$\Rightarrow 4\times 12$

$\Rightarrow 48\ \text{teaspoons}$

So, amar need to add $48\ \text{teaspoons}$ for lemonade

A set of n = 15 pairs of X and Y scores has SSX = 10, SSY = 40, and SP = 30. What is the slope for the regression equation for p

Mumz [18]

Answer:

Step-by-step explanation:

We have given $SS_X=10$ , $SS_Y=40$ and SP =30

We have to find the slope for regression on Y from X

The slope on Y from X is given by $b_{yx}=\frac{SP}{SS_X}$

As we have given the value of SP =30 and value of $SS_X=10$

So slope for regression will be $b_{yx}=\frac{30}{10}=3$
