find the nth tearm

-5 -2 3 10 19

Answers

Given :

The sequence is -5 , -2 , 3 , 10 , 19 .

To Find :

The nth term of the given sequence .

Solution :

Difference between first 2 terms :

-2 - ( -5 ) = 3    1 term

3 - ( -2 ) = 5     2 term    

10 - 3 = 7         3 term

19 - 10 = 9       4 term

From the above observation we can say that difference is increasing in odd number .

So, the nth term will be :

[tex]a_{n+1}= -5 + (2n+1)[/tex]  for n greater than equal to 0.

Hence, this is the required solution.

Betsy has $4.25 and her brother has $16.00 they want to buy two water guns that cost $12.99 each and a bag of water balloons that cost $4.79. Do they have enough money if so how much money will they have left over. If not how much more money will they need?

Answers

Answer:

No they don't have enough money, they need $10.52

Step-by-step explanation:

So first, you will add 4.25+ 16.00 = $20.25 < This is the amount they have.

Second, they want two water guns so 12.99 x 2 = 25.98 < This is the price for the water guns.

Then, add the price of the water ballons to the guns which is $30.77 < This is the cost for everything they want to buy.

Subtract $30.77 from $20.25 to recieve the answer of $10.52

Hope this helps!

I think,  :)

The boxplot below displays the arm spans for 44 student . The statement that is not true from the given option is

Approximately 25% of the arm spans are less than 180 cm

Option C

Given :

The boxplot below displays the arm spans for 44 students.

The five-number summary for the data is 143, 162, 168, 180, and 202.

From the given five number summary we can see that

minimum =143

First Quartile (25%)= 162

Median (50%)= 168

Third quartile (75%)= 180

Maximum =202

Now we analyze the statements

Approximately 75% of the arm spans are less than 180 cm. Its true because third quartile is 75% that is equal to 180

Approximately 50% of the arm spans are less than 168 cm.. Yes its true because median is 168

Approximately 25% of the arm spans are less than 180 cm. It is false because first quartile 25% is 162. So , 25% of the arm spans are less than 162 cm

Approximately 75% of the arm spans are greater than 162 cm. It is true . because  25% of the arm spans are less than 162 cm

What is the approximate volume of this tree trunk if the circumference is 26π inches and the height of the trunk is 22 inches,

Answers

Answer:

Volume = 11680.44 cubic inches

Step-by-step explanation:

Circumference of the trunk of a tree = 2πr

Here, r = radius of the trunk

26π = 2πr

r = 13 inch

Since, volume of the cylindrical trunk = πr²h

= π(13)²(22)

= 3718π

= 11680.44 cubic inches

1) f = 16

2) h = 10

Step-by-step explanation:

all interior angles of a triangle add up to 180 degrees.

1) 46 + 67 + (4f+3) = 180

reduce:

4f+3 = 67

4f = 64

f = 16

2) 60 + 3h + 90 = 180

3h = 30

h = 10
