Answer:

(0.88, 0,65)

Step-by-step explanation:

what do we have to do ? I assume we need to find the crossing point between the 2 lines.

when looking at the graphic, we can already rule out the first, third and fourth option.

none of the coordinates of that point is larger than 1 in any direction or smaller than 0.5.

so, just by looking at things I immediately "bet" on answer option 2 (0.88, 0.65).

but let's check.

y = -2x/5 + 1

y = 3x - 2

for the crossing point both functions must produce the same functional value.

-2x/5 + 1 = 3x - 2

-2x/5 + 5/5 = 15x/5 - 10/5

-2x + 5 = 15x - 10

15 = 17x

x = 15/17 = 0.88...

y = 3×0.88... -2 = 0.65...

hurray, our original observation and "suspicion" is confirmed.

What is the median of the data represented in the line plot?

nevsk [136]

Answer:

The answer is Choice D

Step-by-step explanation

The median is the middle value in the given set of data.

If the data is even, then there will be two middle numbers, then the median is the average of these two middle numbers.

Thus, from the data, it is obvious that the number of data in the given set is 13.

Hence, the middle number is 23.

Therefore, the median of the data is 23.

Paul [167]

13 feet! 12 inches = 1 foot, and think of below ground as negative feet, so it’d be the difference between -1 and 12, which is 13!

Answer:

$10\pi$

Step-by-step explanation:

The penguin swam around half of the perimeter, or circumference, of the pool. The first step is to calculate that. You can find the circumference of a circle by multiplying the diameter by pi. Therefore, the circumference of this island is 20pi. Half of that is $10\pi$ meters. Hope this helps!

What is the best result for h?

Kryger [21]

Answer: First option.

Step-by-step explanation:

To solve for "h" from the given the equation $S=2\pi rh+2\pi r^2$ , you need to:

Apply the Subtraction property of equality and subtract $2\pi r^2$ to both sides of the equation.

Then you need to apply the Division property of equality and divide both sides of the equation by $2\pi r$ .

Then:

$S-2\pi r^2=2\pi rh+2\pi r^2-2\pi r^2\\\\S-2\pi r^2=2\pi rh\\\\\frac{S}{2\pi r}-\frac{2\pi r^2}{2\pi r}=\frac{2\pi rh}{2\pi r}\\\\\frac{S}{2\pi r}-r=h$

Some people love classic cars and antique cars. An antique car is a car that is 25 years old or older. Estimate how many hours i

myrzilka [38]

We have been given that an antique car is a car that is 25 years old or older. We are asked to find the hours it will take a car to become an antique.

We know that 1 year equal to 365 days.

1 day is equal to 24 hours.

To find number of hours in 1 year we will multiply 365 by 24.

$\text{Hours in 1 year}=365\times 24$
