$187.2 Explanation: the total before take is $180 which is 100% tax is 4%. The total plus 4% sales tax is 104% of the original $180. If you shift the numbers two places(as you do when converting % to decimals) you get 1.04. 180 x 1.04 = 187.2

PLEASE HELP ASAP!!
Elza [17]

Answer:

The parabolic equation does not intersect the linear equation.

Explanation:

Given equation's:

  • y = x² − 5x + 9
  • y = -2x

To solve , use substitution method by inserting 2nd equation into 1st

\sf y = x^2 - 5x + 9

when substituted y = -2x

\sf -2x = x^2 - 5x + 9

collect terms

\sf  x^2 - 5x+ 2x + 9=0

simplify

\sf  x^2 - 3x + 9=0

Find discriminant:

\sf b^2 - 4ac

\sf (-3)^2 - 4(1)(9)

\sf -27

As the discriminant is negative, it tell us that they both does not intersect each other.

Forty randomly selected students were asked the number of pairs of sneakers they owned. Let X = the number of pairs of sneakers
eimsori [14]

The mean of sample x is 5.83

The standard deviation is 5.63

<h3>What is standard deviation?</h3>

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

Frequency:  2 2 4 13 13 1

If x is the pair of sneakers owned of the frequency,

mean = 2+2+4+13+13+1/5

= 35/6

= 5.83

The  standard deviation is equal to 5.63.
