Suppose you asked 100 commuters how much they spend each year and obtained a mean of $167 spent on transportation and a standard

Lena [83]

Answer:

The correct answer is "$159 and $175".

Step-by-step explanation:

The give values are:

Mean,

= $167

Standard deviation,

$\sigma$ = $40

Number of commuters,

n = 100

Now,

⇒ $SE=\frac{\sigma}{\sqrt{n} }$

On putting the given values, we get

⇒ $=\frac{40}{\sqrt{100} }$

⇒ $=\frac{40}{10}$

⇒ $=4$

By using the 2 SE rule of thumb, we get

= $$(167 - 2\times 4)$

= $167-8$

= $159$ ($)

Or,

= $(167 + 2\times 4)$

= $167+8$

= $175$ ($)

i.e,

$159 and $175

Suppose a soccer goalie punted the ball in such a way as to kick the ball as far as possible down the field. The height of the b

Alexxx [7]

Answer:

57.98 yards

Step-by-step explanation:

When the ball is on the ground, the height is $y=0$ , therefore:

$y=-0.017x^2+0.98x+0.33$

$0=-0.017x^2+0.98x+0.33$

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-0.98\pm\sqrt{0.98^2-4(-0.017)(0.33)}}{2(-0.017)}$

$x_1=57.98184919$

$x_2=-0.3347903693$

Since distance cannot be negative, the ball landed 57.98 yards down the field from where the goalie kicked the ball.

Answer:

Plug in and determine solution

Step-by-step explanation:#9-11 plug in the degrees C on the left side of the table into the equation and that should give you the degrees F, something like with #9; F = 9/5 (0) + 32.

#12-13, they have a relationship because Celsius can be converted to Farenheit and vise versa
