A nationwide club begins a chapter near you. You research the membership of the club over the past few decades.
Phantasy [73]

Answer:

Option (d)

Step-by-step explanation:

From the given table,

Number of members in 1980 (t = 0) were 5400.

With the period of time number of members increased.

Let the number of years after 1980 = x

Therefore, line of best fit will be in the form of y = mx + b

Where b = Initial number of members = 5400

m = Increase in members in every 5 years duration

So the equation will be,

y = mx + 5400

From the given options,

Equation which matches to our equation is,

y = 310.58x + 5400

For the number of members in year 2022,

x = 2022 - 1980 = 42 years

y = 310.58(42) + 5400

y = 18445

Option (d) will be the answer.

Grace [21]

Answer:

two coins are flipped:

  • if dime land heads and nickel land heads then Allan wins
  • if dime land heads and nickel land tail then Beth wins
  • if dime land tail and nickel land heads then Carlos wins
  • if dime land tail and nickel land tail then Denesha wins

Step-by-step explanation:

The method described above is fair since the probability of each case is 0.25.

If the two coins are flipped:

  • The probability dime land head is 0.5
  • The probability dime land tail is 0.5
  • The probability nickel land head is 0.5
  • The probability nickel land tail is 0.5

Then the probability dime land heads and nickel land heads is 0.5 × 0.5 = 0.25.

The other four cases are calculated similarly and their probability is also 0.25

How to find the derivative of an integral with bounds.
Free_Kalibri [48]

Answer:

The statement of the fundamental theorem of calculus shows the upper limit of the integral as exactly the variable of differentiation. Using the chain rule in combination with the fundamental theorem of calculus we may find derivatives of integrals for which one or the other limit of integration is a function of the variable of differentiation.
