19.Find the median of the distribution 5,9,8,6,3,5,7,12 and 13<br>1<br>-​
77julia77 [94]

Answer:

Your answer is 7

Step-by-step explanation:

First place the numbers in order from lest to greatest, then use your two index fingers to find the middle number from all the numbers, like this:

3, 5, 5, 6, <u>7</u>, 8, 9, 12, 13

P.S. is the number "1" part of the numbers? Because if it is then you need to do the same thing of ordering the numbers and if there are two numbers in between, all you have to do is add & divide.

1, 3, 5, 5, <u>6, 7</u>, 8, 9, 12, 13

6 + 7 = 13; 13/2 = 6.5

If that's the case, then your answer is 6.5.

Oksana_A [137]
The way she put it implies that she will sell many water bottles and only one iced tea. the correct equation would be 1.25x+1.49y=100, as she may sell different amounts of each.

Antonio's toy boat is bobbing in the water under a dock. The vertical distance HHH (in \text{cm}cmstart text, c, m, end text) be
musickatia [10]

Answer: Time t = 33.0 seconds

Step-by-step explanation:

Given that the vertical distance H between the dock and the top of the boat's mast t seconds after its first peak is modeled by the function

H(t) = 5cos( 2π/3 ​t) − 35.5H

Where the maximum vertical distance = 5

At the down position, H(t) = 0

5cos( 2π/3 ​t) − (35.5/100)H = 0

5cos( 2π/3 ​t) − 0.355 × 5 =0

5cos( 2π/3 ​t) − 0.1775 = 0

5cos( 2π/3 ​t) = 0.1775

cos( 2π/3 ​t) = 0.1775/5

cos( 2π/3 ​t) = 0.355

2π/3 ​t = cos^-1 (0.355)

2π/3 ​t = 69.2

2πt = 69.2 × 3

2πt = 207.6

t = 207.6/2π

t = 33.0 seconds

On an algebra test, the highest grade was 42 points higher than the lowest grade. The sum of the two grades was 138. Find the lo
miv72 [106K]


you could use this equation to help you solve it;

x + (x + 42) = 138

the first step is to combine like terms;

2x = 138 -42

2x = 96

X = 96/2

X = 48

we already solved for x now substitute it in the equation I gave you.

48 + (48 + 42) = 138

48 + 90 = 138

hope it helped...if you have any concerns just let me know:)
