Answer:

(-2,-7)

Step-by-step explanation:

All you have to do is draw a graph and draw the point across the x axis in the same row and same distance from the x axis.The distance is 7 so you just change it to -7.

A coin is tossed 72 times. What is a reasonable prediction for the number of

Aneli [31]

Answer :

That’s it, the probability of getting tail on a single coin toss times the number of observations.

In this case, 1/2 * 72 = 36

However, there’s something called chance error. How much do you expect the result to differ from the expected value? It can be calculated as follows:

The Standard Deviation of this experiment is √(0.5)(0.5) =0.5

The Standard Error is √72 (0.5) ≈ 4.18330 round to the nearst tenth is 4

So, the expected value is 36, give or take 4.

And since the number of tails in a toss coin experiment is normally distributed, then you can expect the number of tails to be between -2 and +2 SEs from the expected value 95% of the time.

In other words, if you repeat this experiment a large number of times, you can expect to obtain between 27 and 43 tails 95% of the time.

Hope this helps

This sequence represents the diameters of circles used to create an art project: 2.5 cm, 3.1 cm, 3.7 cm, 4.3 cm Let f(n) represe

vlabodo [156]

The diameters of the circles given are listed as: 2.5 cm, 3.1 cm, 3.7 cm, and 4.3 cm. It can be observed that there is a common difference between the terms of the progression such that the difference between the first two terms is 0.6 cm. The difference between the third and the second is also 0.6, and so on. Thus, the equation that will be able to represent the given is,
<em> f(n) = 2.5 + 0.6(n - 1)</em>

PLZ HELP this doesnt make sense

Otrada [13]

Answer:

No.

If two rectangles are congruent, it means they are the exact same shape and size.

I have uploaded an image with this answer. In the image, you can see two rectangles with the same perimeter. However, they are not congruent because they are not of the same size (even though they are of the same shape - a rectangle).

Hence, two rectangles may not be congruent if they have the same perimeter.

If a person weighs 186 pounds on earth,how much will he weigh on the moon? how many pounds different from his actual weight is t

Hitman42 [59]

If the person weighs 186 pounds on Earth then on the moon it will weigh,

$\frac{weight \: on \: earth}{6} = weight \: on \: moon$
Therefore,
186/6=31 pounds
Its difference is 186-31=155

A car sharing service offers a membership plan with a $50 per month fee that includes 10 hours of driving each month and charges

lord [1]

Answer:

A) F(x) = 50 + ( x - 10 )*9

B) Graph

C) lim ( x ⇒ 10) F(x) = 50

Step-by-step explanation:

A) F(x) = 50 + ( x - 10 )*9 since the first 10 hours are included in initial fee

B) In Annex

C) lim (x ⇒ 10) F(x) = 50 + ( 10 -10)*9

lim ( x ⇒ 10) F(x) = 50 + 0

lim ( x ⇒ 10) F(x) = 50
