good morning,

Answer:

2,6,18

Step-by-step explanation:

6/2=3 and 18/6=3 then 2,6,18 represent a geometric series.

6/2=3 and 10/6≠3 then 2,6,10 doesn’t represent a Géométric series.

Answer:

D) (0,9.5) and (10,1.5)

Step-by-step explanation:

a line of best fit is a line that is drawn through the data points on the scatter plot. Option D is the only answer that draws a linear line through the data points.

Option A makes a short line above the points. if the line is not through the points, it doesn't work

Option B is drawing a positive line (as in it's increasing) and therefore cannot work

Option C draws a line below the points and does not represent the line of best fit for this scatter plot

Mahnoor randomly selects times to walk into a local restaurant and observe the type of music being played. She found that the re

stiks02 [169]

Answer:

The next time Mahnoor visits the restaurant, there is:

--31 % chance for country music

--47% chance of rock & roll

--22% chance of blues

Completed question;

Mahnoor randomly selects times to walk into a local restaurant and observe the type of music being played. She found that the restaurant was playing country 11 times, rock & roll 17 times, and blues 8 times. Use the observed frequencies to create a probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Step-by-step explanation:

Given;

The number of times they were playing each type of music;

Country = 11 times

Roll = 17 times

Blues = 8 times

Total visits of Mahnoor = 11+17+8 = 36

Developing a frequency table and probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Probability = number of favourable outcomes ÷ total number of outcomes.

Music played | Frequency | Probability

country | 11 | 11/36 = .31 or 31%

rock & roll | 17 | 17/36 = .47 or 47%

blues | 8 | 8/36 = .22 or 22%

The driving distance from Chicago to San Francisco is 2,142 miles. The Hathaway family left Chicago on Monday morning, December

Mekhanik [1.2K]

Answer:

They arrive on Monday, December 13th

Step-by-step explanation:

First, we know that this family must drive a total of 2,142 miles.

They average 50 miles per hour and drive 6 hours each day, thus we can see that they drive (50)(6)=300 miles per day.

Now, to know how many days it will take them to drive the total of 2,142 miles we are going to divide the total amount of miles between the number of miles driven per day:

2,142÷300= 7.14

Thus, it takes them 7.14 days to drive 2,142 miles.

If we round this (since the number is greater than 7 this would mean it takes them more than 7 days and they would stop at 7 for the day) to the next digit, we would have that it will take them 8 days to get to San Francisco.

Thus, since they start on December 6th (day 1), December 7th would be day 2 and following this pattern we would have that the eighth day would be December 13th.

Now, since the days repeat every 7 days and we now that December 6th was monday, we would have that the day they arrive to San Francisco (December 13th) is monday too.

A rabbit population doubles every 4 weeks.There are currently five rabbits in a restricted area. If t represents the time in wee

sertanlavr [38]

Doubling formula is this:

$P(t)=P(2)^{\frac{t}{d}}$
where P=initial number of rabbits
t=time
d=time it takes to doulbe

ok, so 4 weeks is the doubling time so that is 4*7=28 days

we wawnt time=98
and oroiginal number of rabbits is 5 so
$P(98)=5(2)^{\frac{98}{28}}$
$P(98)=5(2)^{3.5}$
$P(98)=5(2^3)(\sqrt{2})$
$P(98)=5(8)\sqrt{2}$
$P(98)=40\sqrt{2}$
so P(98)≈56.56
we can't have .56 rabbit so round down or up
about 56 or 57 rabbits in 98 days
