Answer:

The equation 2.5x -10.5 = 64(0.5^x) is true when x=5

Step-by-step explanation:

we need to solve the equation 2.5x -10.5 = 64(0.5^x)

We have to put the given values of x in the functions f(x) and g(x) and find their values

x f(x) = 2.5x -10.5 g(x) = 64(0.5^x)

2 2.5(2)-10.5 = -5.5 64(0.5^2) = 16

3 2.5(3) - 10.5 = -3 64(0.5^3) = 8

4 2.5(4) - 10.5 = -0.5 64(0.5^4) = 4

5 2.5(5) - 10.5 = 2 64(0.5^5) = 2

6 2.5(6) - 10.5 = 4.5 64(0.5^6) = 1

So, we need to solve the equation 2.5x -10.5 = 64(0.5^x)

This holds when x = 5 as shown in the table above.

The correct answer is 5
Solve for x by simplifying both sides of the equation, then isolating the variable.
X=5

Rayshawn has a certain amount of money if he spends $20 then he has 1/3 of the original amount how much money did Rayshawn have

erik [133]

Answer:

Rayshawn originally had $30.

Step-by-step explanation:

i) Rayshawn has a certain amount of money. Let us say this amount is $x.

ii) Rayshawn spends $20 which means that he is left with $(x - 20)

iii) it is also given that amount of money left after spending $20 is $\dfrac{1}{3}$ of the original amount, $x, the amount remaining is $\dfrac{\$x}{3}$ .

iv) from the information given in ii) and iii) we get

$(x - 20) = $\dfrac{\$x}{3}$ , Therefore we get 3x - 60 = x , therefore 2x = 60,

Therefore x = $30. Rayshawn originally had $30.

A data set has a maximum of 84, a minimum of 34, a median of 52.5, an upper quartile of 64, and a lower quartile of 44. Which st

Akimi4 [234]

Answer:

A box and whiskers plot has a box whose endpoints are the interquartile range (25th percentile and 75th percentile), has a dividing line at the median, aka the 50th percentile, and whiskers that extend out to the minimum and the maximum of the data.

Let's sort the info for ease of reference:

min 34, lower quartile 44, median 52.5, upper quartile 64, max 84.

OK, let's go through the statements.

A. The box will go from 44 to 64.

The box goes from the lower quartile to the upper quartile, TRUE

B. A line dividing the box will be at 54.

There's no 54 mentioned at all, FALSE

C. The left whisker will go from 34 to 52.5.

The left whisker goes from the minimum to the lower quartile, 34 to 44 here, FALSE.

D. The right whisker will go from 44 to 84.

The right whisker goes from the upper quartile to the max, 64 to 84 here. FALSE

If this could help, please mark me brainliest! Have an awesome day too!

Answer: To find the critical value, follow these steps.

Compute alpha (α): α = 1 - (confidence level / 100)

Find the critical probability (p*): p* = 1 - α/2.

To express the critical value as a z-score, find the z-score having a cumulative probability equal to the critical probability (p*).
