There are 52 weeks in a year. Ben has lived in london for two fifths of year. How many weeks has ben lived in london?

masha68 [24]

Answer:

$\frac{104}{5}$ weeks or $20\frac{4}{5}$ weeks

Step-by-step explanation:

To do this we can set up a proportion

$\frac{52}{1} *\frac{2}{5}$

This will tell us how many weeks are in 2/5 of a year

Let's evaluate this

$\frac{104}{5}$

We cannot simplifiy this anymore, so we will leave it as an improper fraction, or a mixed number as shown below

$20\frac{4}{5}$ weeks

"Large Sample Proportion Problem. Surveys were conducted in multiple countries and respondents were asked if they felt political

melomori [17]

Answer: 0.0158

Step-by-step explanation:

Given : The data for the United States is that out of 1,000 sampled, 470 indicated yes, they felt political news was reported fairly.

According to the given information we have,

Sample size : n= 1000

Sample proportion: $\hat{p}=\dfrac{470}{1000}=0.47$

The standard error for proportion is given by :-

$S.E.=\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$S.E.=\sqrt{\dfrac{0.47(1-0.47)}{1000}}$

$S.E.=\sqrt{0.0002491}$

$S.E.=0.0157829021412\approx0.0158$

[Rounded to the nearest four decimal places.]

Hence, the standard error for the confidence interval = 0.0158

Find the output, kkk, when the input, ttt, is -7−7minus, 7.<br> k = 10t-19k=10t−19

Sati [7]

The output k at input t = -7 is -89

Step-by-step explanation:

In order to find the value of a expression on given number, we put the number in given expression in place of independent variable

So,

Given expression is:

$k = 10t-19$

It is given that the value of t has to be -7

so putting t=-7 in the expression

$k = 10(-7)-19\\k = -70-19\\k = -89$

Hence,

The output k at input t = -7 is -89
