Answer:

Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft

Step-by-step explanation:

The image attached represent the rectangular park. In this case, the dimensions are;

AB = CD = 215 ft

AC = BD = 150 ft

Total distance walked by Ross = AB + BD = 215 + 150 = 365 ft

Distance walked by Ronnie = AD

∠ABD = right angle triangle, using pythagoras rules;

AD² = AB² + BD²

AD² = 215² + 150²

AD² = 68725

AD = √68725

AD = 262.15 ft

Distance walked by Ronnie = 262.15 ft

Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft

Is (3,-2) a solution to the system below? How do you know?
cricket20 [7]

Step-by-step explanation:

you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.

if yes, it was a solution, and if just only one is false, then it was not a solution.

(3, -2) in

y + 4x = 10

5x - y = 13

so,

-2 + 4×3 = 10

-2 + 12 = 10

10 = 10 true

5×3 - (-2) = 13

15 + 2 = 13

17 = 13 false

so, it was NOT a solution.

A professor pays 25 cents for each blackboard error made in lecture to the student who pointsout the error. In a career ofnyears
arsen [322]

Answer:

The correct answer is "0.0000039110".

Step-by-step explanation:

The given values are:

Y_n\rightarrow N(\mu, \sigma^2)

\mu = 40n

\sigma^2=100n

n=20

then,

The required probability will be:

= P(Y_{20}>1000)

= P(\frac{Y_{20}-\mu}{\sigma} >\frac{1000-40\times 20}{\sqrt{100\times 20} } )

= P(Z>\frac{1000-800}{44.7214} )

= P(Z>\frac{200}{44.7214} )

= P(Z>4.47)

By using the table, we get

= 0.0000039110

Please answer number 1? Thank you
Naddik [55]

Answer:

This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.

Explnation:

z = (x - mu)/sd

z = (2625 - 2600)/50 = 25/50 = 0.5.

Consulting the z-table, P(z <= 0.5) = 0.6915.

P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.

I hope this helped! <3
