The  percent error of Ming’s estimate is 28.571%

Ming estimated that there would be 21 members in his bicycle club by the end of summer

There were actually 15 members at the end of summer

error = 21 - 15 = 6

error percent = error / total x 100

=100( 6 / 21)

= 28.571

Therefore, if Ming estimated that there would be 21 members in his bicycle club by the end of summer. There were actually 15 members at the end of summer the the percent error of Ming’s estimate is 28.571%

I hope this helps.

Step-by-step explanation:

62 + 35 = 97

62 represents the people who think the education helped them grow personally

35 represents the people who somewhat believe it helps them develope specific skills in the work place.

93 in total were interviewed for the "helping them grow personally" question

84 in total for the question that talkings about helping the people develop specific skills and knowlege

93 + 84 = 177

If 97 of those people believe the college degree was useful personally and somewhat useful for learning specific skills, we have to find what is 97 of 177 as a percentage.

54.802259887 rounded is 54.8%

Which means 54.8% of college graduates believe their education was useful for helping them grow personally but not useful for developing specific skills.

The explicit formula which correctly represents the progression represented by the recursive formula above is; a(n) = 8 + 15(n - 1).

It follows from the complete task content that the explicit formula which correctly represents the progression described by the recursive formula; an = an-1 + 15 be determined.

Therefore, by observation of the recursive formula; it follows that the progression is arithmetic with a common difference, d = 15.

Also, since the first term; a₁ = 8, the required explicit formula is;

a(n) = 8 + 15(n - 1).

This follows from the general explicit formula of arithmetic progressions; a(n) = a₁ + (n - 1)d.

The amount Patricia paid as fees on on the account last year was $226.25

What makes up the total cost for Patricia?

Patricia pays a fixed monthly maintenance fee of $17 for every month last year, which means that the total annual maintenance fee last year is the monthly maintenance fee multiplied by 12 months, whereas, the annual check-writing fee is the check-writing fee per check multiplied by the number of checks issued last year.

total annual maintenance fee=monthly maintenance fee *12

monthly maintenance fee=$17

total annual maintenance fee=$17*12

The value of the card in 2005 is $15.49.

A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

When he retired in 1999 his card was worth $7.81 but the value has increased by $1.28 each year since then.

Therefore, the value of the card in 2005 will be:

y = 7.81 + 1.28x

where x = number of years

From 1999 to 2005 is 6 years. This will be:

= 7.81 + 1.28x

= 7.81 + 1.28(6)

= 7.81 + 7.68

The approximate diameter of the circle is 5.77 cm

Given that :

area of circle = 28.3 cm²

How is Area of circle is calculated ?

Area of circle is calculated using formula :

A= πr²

where "π" represents 3.14 and r is radius. So now, according to given information,

Where Pi = 3.14

Hence,

A= πr²

Substitution the value of A in above formula :

28.3 = πr²

28.3 = 3.14r²

r² =28.3/3.14

r² =8.323

√r²=√8.323

r = 2.885

r = 2.885 cm Approximately.

d = 2r

d = 5.77 Approximately.

Therefore, the diameter of the circle is 5.77 cm

The unit rate represented in the equation y = 3/5x is the value multiplying x, that is, the unit rate is 3/5.

In order to find the unit rate of each table, we just need to divide the y-values by the x-values.

So, the unit rate of the first table is:

The value 4/3 is greater than the value 3/5.

In the second table we have that:

The value 4/5 is greater than the value 3/5;

In the third table, we have that:

In order to compare this fraction with 3/5, we need to make them be in the same denominator, so we have to calculate the least common multiple of the denominators.

Since 5 and 31 are prime numbers, the LCM is the product of both numbers.

So we have that:

The number 90/155 is lesser than 93/155, therefore 18/31 is lesser than 3/5, so the answer is the third table.

The answer is 3/10

Explanation:

= 3/4 x 2/5

= 3/4 x 2/5

= 3/2 x 1/5

= 3 x 1 / 2 x 5

= 3 / 2 x 5

Answer:

n + 4

Step-by-step explanation:

n is being used to describe the position of a term.

We can see that the sequence is increasing linearly by 1.

Since the position of the next term is increasing linearly by 1, all we have to do is look at the first term and subtract 1 from it to get our constant (4).

An equation to think about this better would be

n + C = S

C is the constant we are solving for.

We know n = 1.

S is the number corresponding in the sequence with n.

1 + C = 5

Subtract 1 from both sides to isolate C.

C = 4
