jekas [21]

Answer:

     64 : 343

Step-by-step explanation:

When working with scale factors

Lengths are related by the scale factor

perimeters are related by the scale factor

areas are related by the scale factor squared

volumes are related by the scale factor cubed

The scale factor is 4:7

The volumes are related by 4^3 : 7^3

Using this distribution, find the probability
kaheart [24]

Answer:

P = 0.3

Step-by-step explanation:

Here, we are to use the probability distribution in the table to calculate the probability that a children has 4 or more shoes in his or her closet

When we say 4 or more, what we mean by this is that the teenager has 4 shoes or 5 shoes

In probability expressions, when we use the term ‘or’ we are simply talking about adding the terms involved

So what we can do here is to add the probability that the teenager has 4 shoes to the probability that the teenager has five shoes

From the table that would be; 0.1 + 0.2 = 0.3

Help please i don’t know how to do it
nekit [7.7K]

Answer:

x + 3y = 15

Step-by-step explanation:

Line is passing through the points (3, \:4) = (x_1,\:y_1)\:and\: (9, 2)=(x_2,\:y_2)

Slope of line (m)= (2 - 4)/(9 - 3) = -2/6 = -1/3

Equation of line in point-slope form is given as:

y-y_1 =m(x-x_1)

Plugging the values of x_1,\: y_1\: and \: m in the above equation we find:

y-4 =-\frac{1}{3}(x-3)

\implies 3y-12 =-x+3

\implies x+ 3y =12+3

\implies \huge {\orange{\boxed{x+ 3y = 15}}}

This is the required equation of line in the form \red{\bold{ax + by = c}}
