Yes, those answers are correct!
To find a median you’d want to find the middle value. Since there are 15 numbers here, you would look for the eighth, as there are seven on either side. If it were an even number, you would look for the two middle numbers, add them, and then divide that by two.
To find the mean, you want to add all the values and divide them by how many there are. So you’d solve for 76+76+78+80+80+80+82+82+83+85+85+85+88+88+110 and than divide the sum of that by 15, since there are 15 total values.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle

romanna [79]

Answer:

54 in

Step-by-step explanation:

Use Pythagorean to find the missing side x of the triangle.

<u>It is a hypotenuse with other sides 18 in and half of 15 in:</u>

$x = \sqrt{18^2+(15/2)^2} =\sqrt{380.25} =19.5$

<u>The perimeter is:</u>

P = 2*19.5 + 15 = 54

A bus covers a distance of 90km at a uniform speed. Had the speed been 15km/hour it would have taken 30 minutes less for the jou

Brrunno [24]

Answer:

Step-by-step explanation

Let's say d = distance, r = speed and t = time

We know the distance formula is :

distance = speed x time

d = r multiplied by t

d = rt

If the speed is 15km/hr, the time would be 30 minutes shorter.

Since d = rt,

90 = 15t

t = 6,

This means the time taken for the bus to complete the journey at 15km/hr would be 6hrs.

Originally though, the journey takes 30 minutes longer.

So we can say t = 6.5 hrs , and we know d = 90

Now we use the distance formula:

d = rt, since we want to find the original speed, we want to find r.

Speed = distance/time

r = d/t

r = 90/6.5

r = 180/13

Therefore the original speed is 180/13 km/hr
