Answer:

Step-by-step explanation:

Since we are given self defining variables, h is obviously referring to the plant's height and y is referring to the plant's years or age.

Then, since a plant's height is 1.4 times its age, age multiplied by 1.4 should be the plants height.

The equation would come out to $h=1.4y$

5y-x=10 solve for y

shusha [124]

$5y-x=10\\\\ 5y=10+x \ |:5 \ Both \ sides \\\\ y=\frac{10}{5}+\frac{x}{5}\\\\ y=2+\frac{x}{5}$

because
$5y-x=5(2+\frac{x}{5})-x=5\cdot 2 +\frac{x}{\not5}\cdot 5 - x= 10+x-x=10$

The Cinemania theater showed 108 different movies last year. Of those, 15 movies were action movies. Based on this data, what is

natita [175]

Answer:

A reasonable estimate of the probability is equal to $0.1389$ or $13.89\%$

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

Let

x------> size of the event space

y-----> size of the sample space

$P=\frac{x}{y}$

In this problem we have

$x=15$

$y=108$

substitute

$P=\frac{15}{108}=0.1389$

Convert to percentage

$0.1389*100=13.89\%$

Whats 1 1..........................................?

olasank [31]

<span>It depends on the number system and the defined operation.

In simple addition we get 1+1=2
In group theory, provided a binary operation as addition modulo 2 is defined, we get (1+1) mod 2 = 0

For A = {6, 10, 14) and B=(3,5,7) find the<br> relation y = 1/2 x in AxB

nexus9112 [7]

By taking A as our domain and B as our range, we will see that the relation is {(6, 3), (10, 5), (14, 7)}

Here we have:

A = {6, 10, 14}
B = {3, 5, 7}

And we want to find the relation:

y = (1/2)*x in AxB.

So, we take values from A, and we input them in the given function, and then we must see if the outcome is in B.

For each value in A we will have:

y = (1/2)*6 = 3

(6, 3)

y = (1/2)*10 = 5

(10, 5)

y = (1/2)*14 = 7

(14, 7)

So we have 3 points that define the relation in AxB:

{(6, 3), (10, 5), (14, 7)}

Vladimir [108]

180 minus 68. 68+2 is 70. 70 + 30= 100 100 + 80 = 180

80+30+2= 110 +2= 112. 112 + 68 = 180
