Find the slope of each line defined below and compare their values. Down-drop Less than, greater than, equal to.​
Agata [3.3K]

Answer:

\displaystyle equal\:to \\ Line\:B: 1 \\ Line\:A: -1

Step-by-step explanation:

Starting from the y-intercept of \displaystyle [0, -2],you do \displaystyle \frac{rise}{run}by either moving one block <em>south</em> over one block <em>west</em> or one block <em>north</em> over one block <em>east</em> [<em>west</em> and <em>south</em> are negatives].

Now, for Line <em>A</em>, we need to convert this <em>Linear</em><em> </em>Standard Equation to Slope-Intercept Form, \displaystyle y = mx + b,where the slope is represented by <em>m</em>:

x + y = 3

- x - x

__________

\displaystyle y = -x + 3

So, the slope of Line <em>A</em> is \displaystyle -1,and since −1 is less than 1, <em>less than</em> would be the answer, HOWEVER, they BOTH have some slope of 1, so since −1 is the negative <em>absolute</em><em> </em><em>value</em><em> </em>of 1, <em>equal</em><em> </em><em>to</em><em> </em>will be the answer.

I am joyous to assist you anytime.

If h(x)=6-x what is the value of (h•h)(110)
Irina18 [472]

The given function : h(x) = 6 - x

We know that for any functions f(x) and g(x)

f*g (x)=f(x)\times g(x)

Therefore , h*h (x)=h(x)\times h(x)

h*h (x)=(6-x)(6-x)=(6-x)^2

h*h (x)=(6)^2-2(6)(x)+x^2 [ Using identity   (a-b)^2=a^2+2ab+b^2 ]

h*h (x)=36-12(x)+x^2

\-------->\ h*h (x)=36-12(x)+x^2 Now, at x= 10 , we get

h*h (10)=36-12(10)+(10)^2

h*h (10)=36-120+100=36+100-120=136-120=16

Hence, the value of (h*h)(10) = 16

hoped it helped

In a typical children's soccer game, there is one goal scored approximately every 18 minutes. The number of goals scored follows
Alja [10]

Answer:

2.24

Step-by-step explanation:

The probability formula using a Poisson distribution is:

P(k\ events) = \frac{\lambda^{k}e^{-\lambda}}{k!} \\\lambda\ is\ the\ average\ number\ of\ events\ per\ interval \\e\ is\ euler's\ number \\k\ is\ the\ number\ of\ events\ you\ want\ to\ calculate

λ = 90 / 18 = 5 average goals per interval (interval = a game)

So if for example you were interested in the probability of making 2 goals in a game

k = 2

P(k = 2) = \frac{5^{2}e^{-5}}{2!} = 0.084

This was just an example,

The standard deviation is \sqrt{\lambda}

\sigma = \sqrt{\lambda} \\\sigma = \sqrt{5} \\\sigma = 2.24
