Answer: 121 2/3 days

Step-by-step explanation:

Number of days in a year = 365 days

Number of friends = 3 friends

The number of days each year that Alisa need to walk the dog will be:

= Number of days in a year / Number of friends.

= 365 / 3

= 121 2/3 days

= 121 days + (2/3 × 24hours)

= 121 days 16 hours

Answer:

The sample size is $n =419$

Step-by-step explanation:

From the question we are told that

The population proportion is $p = 0.45$

The margin of error is $E = 0.04$

Given that the confidence level is 90%

Then the level of significance can be mathematically represented as

$\alpha = 100 -90$

$\alpha = 10\%$

$\alpha = 0.10$

Next we obtain the level of significance from the normal distribution table the value is

$Z_{\frac{\alpha }{2} } = 1.645$

Generally the sample size is mathematically represented as

$n = [ \frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * p(1- p )$

substituting values

$n = [ \frac{1.645 }{0.04} ]^2 * 0.45(1- 0.45 )$

$n =419$

Write the sentence as an equation. 323 decreased by d equals 369

jarptica [38.1K]

$323 - d = 369$

Thus, d has to be negative, and you get:

$-d = 46$
$d = -46$
