The height of the arrow at 2.5 seconds is 71 feet.

Given:

An arrow released from a bow, traveling towards a target 200 yards away,reaches a max height of 42.6 ft in only 1.5 seconds.

1.5 seconds = 42.6 feet

divide by 1.5 on both sides.

1 sec = 28.4 feet

0.5 sec = 28.4/2

0.5 sec = 14.2 feet

2.5 sec = 1.5 sec + 1 sec

= 42.6 + 28.4

= 71 feet

Therefore The height of the arrow at 2.5 seconds is 71 feet.

The amount engine oil which should be added to a jerry can that contains 4.3 gallons of​ gas is 0.172 gallons.

Given that arborist is preparing the fuel mix for her chainsaw before climbing a tree to remove a dead limb when two-stroke chainsaw requires a 4​% mix of engine oil to gas and the amount of oil should be 4​% of the amount of gas.

We want to find the amount of engine oil which should be added to a jerry can that contains 4.3 gallons of​ gas.

To find the amount of engine oil convert the mixture of engine oil to gas into decimal.

4%=4/100

4%=0.04

Now, we will multiply the above mixture with 4.3 gallons of gas is

4.3×0.04=0.172 gallons

Hence, the amount of engine oil which should be added to a jerry can that contains 4.3 gallons of​ gas when two-stroke chainsaw requires a 4​% mix of engine oil to gas is 0.172 gallons.

Answer: 1/8, Division equation: 1/3 divided by 8/3

Step-by-step explanation:

Step 1: Write this problem as an equation, of means multiply so the equation is 1/3 x 3/8.

Step 2: Solve the equation by multiplying the numerators and the denominators. You get 3/24.

Step 3: Simplify by dividing the numerator and denominator by their gcf. In this case it is 3. So, 1/3 of 3/8 is 1/8.

Step 4: Now we need to get the division equation of 1/3 x 3/8, for this you do the same thing as if we had to actually solve the division equation with fraction, just for changing multiplication to division instead. I am talking about keep change flip. You keep the first fraction the same. you change the operation to it's opposite ,and you flip the numerator and denominator in the second fraction. When we do this we get our division equation of 1/3 divided by 8/3.

Examining the rainfall data for the two periods a conclusion is that the range of the values are period 1 has low variability while period 2 has high variability

period 1: 0.6

period 2: 4

The range in statistics refers to the distribution of data between the lowest and greatest value in the distribution. It is a widely used indicator of variation.

Measurements of variability provide you with descriptive statistics for summarizing your data set in addition to measures of central tendency.

By deducting the lowest value from the greatest value, the range is computed. A short range indicates low variability in a distribution, whereas a big range denotes significant variability.

The range is

period 1: 2.5 - 1.9 = 0.6

period 2: 4.7 - 0.7 = 4

The growth formula for the given population is P = 182eⁿˣ and the population in 2004 is 186.98 million

Growth function:

Basically, the growth function means the pattern of data that shows greater increases with passing time, creating the curve of an exponential function.

Given,

A country's population in 1994 was 182 million. In 2002 it was 186 million.

Here we need to find the growth formula and the population in 2004.

According to the given problem, let us consider that the

final population P,

the starting population A, and

the time passed t.

Here we need to determine the value of the growth factor k.

And it can be calculated using the information for the years 1994 and 2002.

Here we know that, A will be 182 million (the population in 1994), P will be 186 million (the population in 2002), and t will be 8 years (the number of years between 1994 and 2002):

⇒186 = 182eⁿˣ⁸

⇒186/182 = e⁸ⁿ

Now, by applying ln to both sides of the equation:

⇒ln(186/182) = ln(e⁸ⁿ)

Using the laws of logarithms:

=> 8n = ln(186) - ln(182)

=> n = [ln(186) - ln(182)] / 8

=> n = 0.0027

Now, let's use this information to determine P in 2004.

Here the value of A will still be 182 million, but t will be 10 years.

Now, we have to apply these values then we get,

=> P = 182e⁰°⁰⁰²⁷ˣ¹⁰

=> P = 182e⁰°⁰²⁷

=> P = 182 x 1.0273

=> P = 186.98

Therefore, there are  186.98 million in 2004.

The   proceeds  is  $7,566.67 and  the effective rate charged by the bank to the nearest is 6.87%.

Given data:

Principal = $8,000

Rate =6 1/2% or 6.5%

Term= 300 Days

a. Proceeds

Interest  = Principal  x Rate  x Time

Interest  = $8,000 x 6.50% x 300/360

Interest = $8,000 x 0.065 x 0.8333

Interest  = $433.33

Now let find the Proceeds:

Proceeds = $8,000 - 433.33

Proceeds = $7,566.67

b. Effective Interest Rate:

Effective Interest Rate = 433.33 / 7566.67 x 300/360

Effective Interest Rate = 433.33 / 6305.56

Effective Interest Rate = 0.0687 × 100

The probability of the event E i.e an odd number less than 9 is 0.4.

The probability of an event is a ratio of number of favorable outcomes to total number of outcomes. The sum of all probabilities of events must be equal to one. The probability of an event must not be greater than 1.

In event E i.e an odd number less than 9, the number of favorable outcome is 4 i.e. {1,3,5,7}.

The total number of outcomes is whole set S i.e. 10.

So, the probability of event E will be,

Step-by-step explanation:

this is a college question ????

and you don't know how to do it ? what happened to you in elementary school ?

there are many different techniques. everybody thinks theirs is the fastest or easiest to understand.

after all, this is just "playing" with numbers, the factors embedded within the dividend.

this is mine. when I was in elementary school, we called this the "long division" :

62.79 ÷ 23 =

we pick the first few positions from the left of the dividend, where we are sure, the divisor fits at least once.

in our case here : 62.

we do an integer divide of 62/23 = 2 (for 3 the dividend would have to be at least 69). this 2 is our first digit of the quotient.

62.79 ÷ 23 = 2

now we multiply the divisor by that digit and subtract the result from the dividend. this gives us a remainder of 16, and we pull down the next position (7) :

62.79 ÷ 23 = 2

- 46

---------

167

now, we pulled the first digit after the decimal point, and we need to set the decimal point there in our quotient :

62.79 ÷ 23 = 2.

- 46

---------

167

now, we repeat the process by integer dividing this new dividend (167) by the divisor (23)

167/23 = 7

this 7 becomes the next digit in our quotient. and we repeat the process of multiplying this by the divisor and subtracting the result from the dividend. this gives us a remainder (6), and we pull down the next digit (9).

62.79 ÷ 23 = 2.7

- 46

---------

167

- 161

----------

69

and again, we repeat by integer dividing the new dividend (69) by the divisor (23)

69/23 = 3

this 3 is the next digit in our quotient.

we multiply it with the divisor and subtract the result from the dividend.

if the remainder is still not 0, we need to repeat the process by pulling the next digit, which would be an invisible 0. and continue.

but luckily, after this the remainder is 0, and we are finished.

62.79 ÷ 23 = 2.73

- 46

---------

167

- 161

----------

69

- 69

--------------

0

so, 62.79 ÷ 23 = 2.73 and 0 remainder.

Every following word in a sequence known as a geometric progression (GP) is created by multiplying every previous term by a constant amount, or "common ratio." Another name for this progression is a pattern-following geometric sequence of numbers.

To find out the common ratio we have to divide the second term by the first term,
