Explanation:

this function is in the form of

y

=

m

x

+

q

with

m

=

3

,

q

=

0

so it's an straight line: ascending [

Help me please.<br><br> ------------------------------------------------
ladessa [460]

Answer:

Alicia

Step-by-step explanation:

First, convert the mixed fractions into improper fractions

<u>Alicia</u>

Distance: 5 1/2 = 11/2 = 5.5 miles

Time: 1 2/5 = 7/5 = 1.4 hours

<u>Carlos</u>

Distance: 8 1/8 = 65/8 = 8.125 miles

Time: 2 1/2 = 5/2 = 2.5 hours

<u>Henry</u>

Distance: 3 2/3 = 11/3 = 3.6 reoccuring miles

Time: 1 1/10 = 11/10 = 1.1 hours

<u>Zoe</u>

Distance: 4 2/3 = 14/3 = 4.6 reoccuring miles

Time: 1 3/10 = 13/10 = 1.3 hours

After that, divide the distance by the time

Alicia = 5.5 / 1.4 = 3.93 ( 3 s.f )

Carlos = 8.125 / 2.5 = 3.25

Henry = 3.6 re / 1.1 = 3.3 reoccuring

Zoe = 4.6 / 1.3 = 3.54 ( 3 s.f )

Looking at these answers, we determine which rate is the greatest

Alicia = 3.93

Carlos = 3.25

Henry = 3.3 re

Zoe = 3.54

Alicia hiked the highest rate.

A line is represented by the equation y = x + 2. Suppose the slope of the line was doubled and the value of the y-intercept was
Hitman42 [59]

Answer:

A.y=2x+1

Step-by-step explanation:

y = x+2

This is in the form y= mx+b

where m is the slope and b is the y intercept

m=1  we are doubling it

m=2

The y intercept is 2, we are dividing by 2

2/2 =1

b=1

y = mx+b

y = 2x+1

In a city with 40000 people, each person has a 0.00020 probability of committing a crime each hour. What is the probability that
galina1969 [7]

Answer:

2.86% probability that there are exactly 3 crimes during the next hour

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given time interval.

In a city with 40000 people, each person has a 0.00020 probability of committing a crime each hour.

So \mu = 40000*0.0002 = 8

What is the probability that there are exactly 3 crimes during the next hour

This is P(X = 3).

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 3) = \frac{e^{-8}*(8)^{3}}{(3)!} = 0.0286

2.86% probability that there are exactly 3 crimes during the next hour

Third-degree, with zeros of -3,-1, and 2, and passes through the point (3,6).
Y_Kistochka [10]

Answer:

Below.

Step-by-step explanation:

In factor form this is:

f(x) = a(x + 3)(x + 1)(x - 2)     where a is a number to be found.

As it passes through (3, 6) we have:

6 = a(3 + 3)(3 + 1)(3 - 2)

24a = 6

a = 1/4.

So f(x) =  1/4(x + 3)(x + 1)(x - 2)

In general form this is:

f(x) = 1/4 x^3 + 1/2 x^2 - 5/4 x - 3/2
