the anwser would most likely be 3 because you want the LCM

If a person rows to his favorite fishing spot 14 miles downstream in the same amount of time that he rows 2 miles upstream and i

Maru [420]

We will use distance formula which states:

$d=r \times t$

where 'd' is the distance, 'r' is rate or speed and 't' is time taken.

So, $t=\frac{d}{r}$

Let 'u' be the speed of boat in still water.

A person rows 14 miles downstream to the fishing spot.

So, the speed of boat downstream = (u+6) mph

Time taken by boat to go downstream = $\frac{14}{u+6}$ hr

He rows 2 miles upstream from the fishing spot.

So, the speed of boat upstream = (u-6) mph

Time taken by boat to go upstream = $\frac{2}{u-6}$ hr

Since, The person took same amount of time in going downstream and then going upstream.

So, $\frac{14}{u+6}=\frac{2}{u-6}$

Cross multiplying, we get

$14 (u-6)= 2(u+6)$

$14u - 84 = 2u + 12$

$12u = 96$

u = 8

So, speed of boat in still water is 8mph.

Now, Time taken in going downstream = $\frac{14}{u+6}$

= $\frac{14}{8+6}$

= 1 hr

Now, Time taken in going upstream = $\frac{2}{u-6}$

= $\frac{2}{8-6}$

= 1 hr

So, total time taken to cover 16 miles is 2 hours.

In , the Pew Internet & American Life Project asked teens aged to several questions about their attitudes toward social medi

Complete Question

The complete question is shown on the first uploaded image

Answer:

a

$\^ p_1 = 0.8102$

b

$\^ p_2 = 0.6904$

c

$\^ p_3 = 0.3701$

Step-by-step explanation:

From the question we are told that

The sample size is n = 743

The number that said social media makes them feel more connected to what is going on in their friends' lives is k = 602

The number that said social media helps them interact with a more diverse group of people is y = 513

The number that said feel pressure to post content that will get a lot of likes and comments is c = 275

Generally a point estimate of the proportion of teens aged 13 to 17 who say social media makes them feel more connected to what is going on in their friends' lives is mathematically represented as

$\^ p_1 = \frac{k}{n}$

=> $\^ p_1 = \frac{602}{743 }$ \

=> $\^ p_1 = 0.8102$

Generally a point estimate of the proportion of teens aged 13 to 17 who say social media helps them interact with a more diverse group of people is mathematically represented as

$\^ p_2 = \frac{k}{n}$

=> $\^ p_2 = \frac{513}{743 }$ \

=> $\^ p_2 = 0.6904$

Generally a point estimate of the proportion of teens aged 13 to 17 who feel pressure to post content that will get a lot of likes and comments is mathematically represented as

$\^ p_3 = \frac{k}{n}$

=> $\^ p_3 = \frac{275}{743 }$

=> $\^ p_3 = 0.3701$

What is the graph of the function f(t)= 5 sin 3t

svlad2 [7]

Answer:

in the graph

Step-by-step explanation:

the function g(t)= sin t is a periodic function with amplitude a0= 1 and period T0=2 $\pi$

For our case, the 5 that multiplies g (t) increases the amplitude so that a = 5 * 1 = 5 and the 3 that multiplies the variable increases the period being T = 2 $\pi$ *1/3 = 2 $\pi$ /3
