A zoo measured the wingspan, in millimeters, of 9 butterflies.
55 50 54 57 50 55 53 52 55
What is the median length of the wingspans?

50 millimeters

54 millimeters

55 millimeters

57 millimeters

Answers

Answer:

The median is the middle of your data when it is arranged in order.

Since you have 9 data points, the median will be the 5th value.

Your data in numerical order would be:

50 50 52 53 54 55 55 55 57

Therefore, the median is 54mm

Step-by-step explanation:

Answer:

B. 54

Step-by-step explanation:

Put all numbers from least to greatest in order and cross one out on each side until you reach the final number in the middle with even crosses on each side.

50, 50, 52, 53, 54, 55, 55, 55, 57

50- crossed

57- crossed

50- crossed

55- crossed

52- crossed

55- crossed

53- crossed

55- crossed

Which leaves 54! Hope this helps, good luck! :)

Anyone with a knee injury or any doctor! What does it mean if my knee popped locked up all in like 1.5 seconds and then it now hurts to bend but not alot and i can wiggle my kneecap like a lot. This is the 2nd time in like 7-9 months! Please help! Comment if there is no more answers left!

Answers

Answer:

Knee pain can have causes that aren't due to underlying disease. Examples include heavy physical activity, lack of use, injuries such as sprains or strains, sitting in a constrained area, or sitting on knees for a prolonged period.

Step-by-step explanation:

possibly Chondro malacia

Damage to the cartilage under the kneecap.

Symptoms may include

Knee pain

Cracking joints

Swelling of the knee

Please go to your doctor...ik it hard with cov id and everything

It could be hereditary, or it could just be a weak muscle. I have knee problems. If it’s just your knee cap that is dislocating you can do simple exercises to strengthen the muscle around it to hold it in place. If it’s your actual knee you should get it checked out to see if there is anything else going on. If it continues and there’s nothing “wrong” they’ll have you do physical therapy. When this dislocation happens, keep your knee up above your heart and ice it. After you pop it back on. And take pain relief. Wear a knee brace as well

Answers

Answer:

11/30

Step-by-step explanation:

You need to convert everything to a common denominator, so you would change everything into x/30 so 7/10 is equal to 21/30 and 1/3 is equal to 10/30 so you would just subtract 21-10 and get 11/30

1) 1512 cubic inches 2) 54 cubic feet

Step-by-step explanation:

The first one is calculated like so: first you subtract 9 from 15 which is 6 to get the height of the empty bit, then you multiply 6 by 18 and 14 to get the volume and the answer is 1512 inches squared

For the second you split into two pieces the first one has side lengths 2, 3 and 2 so the volume is 12 and the second has side lengths 7, 3, 2 so its volume is 42 finally you add them to get 54 cubic feed

Find the slope of each line​

Answers

Rise over run

5 up over 4 left

-5/4 is your slope

Answer: The slope is -5/4.

Step-by-step explanation: The slope of a line refers to its direction and steepness. The slope can be expressed as a fraction that is commonly refered to as rise over run. In order to find the slope of a line, you need to find two coordinates on the line and use the "rise over run" method. The numerator (rise) is how many units up or down while the denominator (run) is how many units left or right. There are two given points on this specific line. To get from one to the other, you must go down 5 units and to the right 4 units; therefore, the slope, or rise over run, is -5/4.
