Answer: s-6

Step-by-step explanation:difference means subtract so that why there subtract sign. And you are trying to find the difference of s and 6 so you write s -6.

Hope it help and please give Brainliest if it did thanks ;)

Write an equation in point slope form of the line through point J(4,1) with slope -4

lara [203]

Answer:

y - 1 = -4(x - 4)

Step-by-step explanation:

The point-slope form looks like y-k = m(x-h), where (h,k) is a point on the line and m is the slope.

Here, y - 1 = -4(x - 4). This is in point-slope form.

Assume that the number of messages input to a communication channel in an Exponential distribution with 7 messages arriving in a

NARA [144]

The probability that more than 3 messages will arrive during a 30-second interval is $P(X=n)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^n}{n!}$ .

According to the statement

we have given that the an Exponential distribution with 7 messages arriving in a 10 second period and we have to find the probability that more than 3 messages will arrive during a 30-second interval.

So, For this purpose, we know that the

The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event.

And the given information is that :

3 messages will arrive during a 30-second interval.

Then

Probability = P(X=1) + P(X=2) + P(X=3).Then

The probability become according to the exponential distribution:

$P(X=1)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^1}{1!}\\P(X=2)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^2}{2!}\\P(X=3)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^3}{3!}\\$

And then substitute the values in it then

$Probability = \dfrac{e^{-0.3 \times 20} (0.3 \times 20)^1}{1!}\ +\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^2}{2!}\ + \dfrac{e^{-0.3 \times 20} (0.3 \times 20)^3}{3!}\\$

This is the probability.

So, The probability that more than 3 messages will arrive during a 30-second interval is $P(X=n)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^n}{n!}$ .

Please solve in the next 10 minutes pleaseeee

Alex787 [66]

Answer:

43.82 mph

266.67 feet

Step-by-step explanation:

Given :

S = √30fl

S = speed of car

f = drag Coefficient

l = Length of skid mark

If f = 0.8 ; l = 80 feets

s = √30fl

s = √(30*0.8*80)

s = √1920

s = 43.817

s = 43.82 mph

B.)

s = 80 mph

f = 0.8

s = √30fl

80 = √30*0.8*l

80 = √24l

Square both sides

80² = 24l

6400 = 24l

l = 6400/24

l = 266.67 feets

HELP! DUE AT 5 PM!! 10 BRAINLIST!<br><br> 3x -15x - 30 > 54

ryzh [129]

Answer:x<-7

Step-by-step explanation:

3x -15x - 30 > 54

-12x-30>54

-12x<54+30

I moved 30 from left side to right which becomes positive and > becomes <

-12x<84

-12x/-12<84/-12 I used my calculator to do this

x<-7

F(x) = 9x-7. If f(x)= -7, find x.

svlad2 [7]

Answer: the answer is 56

Step-by-step explanation: since the f(x) is -7 it would be 9 times -7 then minus 7 and get the answer.
