Which quantity is used to generate the error bars on a graph?

1 answer:

6 0

The error bars on a graph the error or uncertainty of the measure graphed. You can use diffferent statistics to represent this deviation or error, so your graph should state which is being used.

Of the four options listed the only one valid, a frequently used, is the standard deviation (you could use, two standard deviations, or an interval of confidence).

The answer is standard deviation.

You want to go to laser tagging but would like to find out which place has the better deal laser flash charges an initial fee of

mariarad [96]

Answer:

The cost at both Laser Flash and Laser storm would be the same after 4 games

Step-by-step explanation:

Let the number of games be represented as x

Laser flash charges an initial fee of $16 for gear and $4 per game

For Laser flash , the Equation is:

$16 + $4 × x

y= 16 + 4x

Laser storm charges an initial fee of $20 for gear and $3 per game

$20 + $3 × x

y = 20 + 3x

Hence: Equating both costs to each other

Laser flash = Laser Storm

16 + 4x = 20 + 3x

Collect like terms

4x - 3x = 20 - 16

x = 4 games

The cost at both Laser Flash and Laser storm would be the same after 4 games

Rewrite the following expression X^9/7

KonstantinChe [14]

Answer:

$x\sqrt[7]{x^{2} }$ (D)

Step-by-step explanation:

Given: $x^{\frac{9}{7} }$

To find: Simplify the given expression

Solution: Simplyfying, we get,

$x^{\frac{9}{7} } =x^{\frac{7}{7} +\frac{2}{7} }$

$=x^{1} *x^{\frac{2}{7} } \\=x*x^{\frac{2}{7} } \\=x=\sqrt[7]{x^{2} }$

Therefore, $x\frac{9}{7}$ can be written as $x\sqrt[7]{x^{2} }$

What is the total cost

Elina [12.6K]

Answer:

Step-by-step explanation:

We need to first find the perimeter of this oddly-shaped rink. We have a rectangle for which we are enclosing 3 of its sides, and the fourth "side" is a half-circle. Let's find the perimeter (or circumference) of the circle, divide it in half because we have half a circle, then add in the remaining 3 sides from the rectangle, shall we?

C = πd. The diameter of the circle is the same as the shorter length in the rectangle, 26. Therefore,

C = (3.14)(26) so

C = 81.64 m for a whole circle, and for half of that circle, the circumference is

C = 40.82 m

Now we can find the perimeter of the rink:

40.82 + 61 + 26 + 61 = p so

p = 188.82 m

If the fencing costs $6.20 per meter and we have 188.82 m, then the total cost is

$cost=\frac{6.20dollars}{meter}*188.82meters$ . The label "meter" cancels out, leaving us with

cost = $1170.82
