Can someone please help me find the measure of the exterior angle.

Answers

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  because they are supplementary angles

k = 140°

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  

k = 140°

3. B

4. C

5. A

5. F

Step-by-step explanation:

The median can be found at the line inside of the box, the heaviest weight would be found at the right end of the line, and the smallest weight would be found at the left, the interquartile range is the difference of one end of the box to the other, and the range is the difference of the largest number of the entire diagram, from the smallest number.

Hope this helps you!

Answer:

Florida: The weight range = 10

Tennessee: The interquartile range = 4

Tennesse: Median Weight = 76

Florida: Median Weight = 80

Florida: Weight of the heaviest child =  84

Tennesse: Weight of the smallest child = 71

Step-by-step explanation:

Florida: How to find the weight range

The range of a data set is the difference between the minimum and maximum. To find the range, calculate xn minus x1.

R = xn − x1

Therefore, the weight range in Florida is 10

Tennessee: How to find the interquartile range

To find the interquartile range (IQR), ​first, find the median (middle value) of the lower and upper half of the data set. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

71, 72, 73, 74, 75, 76, 77, 78, 79, 80

Q1 = 74

Q2 = 78

78 - 74 = 4

Therefore, the interquartile range in Tennesse is 4

Tennesse: Median Weight

The median x˜ is the data value separating the upper half of a data set from the lower half.

Arrange data values from lowest to the highest value

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

If there are 2 data values in the middle the median is the mean of those 2 values.

x˜ = 75.5

Therefore, the median weight of Tennesse is 76

Florida: Median Weight

The median x˜ is the data value separating the upper half of a data set from the lower half.

Arrange data values from lowest to the highest value

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

If there are 2 data values in the middle the median is the mean of those 2 values.

x˜ = 79

Therefore, the median weight of Florida is 80

Florida: Weight of the heaviest child

Since the smallest number in Florida is 84,

Therefore, the weight of the heaviest child in Florida is 84

Tennesse: Weight of the smallest child

Since the smallest number in Tennesse is 71,

Therefore, the weight of the smallest child in Tennesse is 71

Solve 24 =y +17.5 y=

Answers

-6.5


17.5-24 you place the 24 near the 17.5 and make 24 a negative so the equation would be

y= 17.5-24

Answer:

[tex] \sf \: y = 6.5[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of y.

The equation is,

→ 24 = y + 17.5

Then the value of y will be,

→ 24 = y + 17.5

→ y + 17.5 = 24

→ y = 24 - 17.5

→ [ y = 6.5 ]

Hence, the value of y is 6.5.

I need 3 reasons why it is important to keep gorillas from becoming extinct. I'll give brainliest. I know that this isnt math but more people answer questions that are in math so... yea

Answers

Answer:

1. gorillas are able to spread the seeds of larger fruits that other, smaller animals are incapable of consuming. When gorillas consume a fruit and later expel the seeds, they are helping to perpetuate diverse, supportive ecosystems.

2. The forest will never be same if the gorillas are gone. Illegal coltan mines (minerals used in smart phone and computer production) are controlled by militia in the gorilla habitat (DRC) and contribute to habitat destruction and poaching.

3. Many local indigenous tribes and communities living alongside the gorilla habitat consider the gorillas to be their patron gods. The Kisimba clan (Bahumba) believe they descended from the gorillas. Their traditional tale tells a story of a gorilla rescuing a man that was lost and stuck high up in a tree. To save the man, a gorilla climbed up the tree and gently placed him on his silver back before carrying him back to safety.

Step-by-step explanation:

Ultimately we cant let gorillas go for much more reasons then just these 3 and they are used for so much in all of their respected environments.
