Answer:

Step-by-step explanation:

(4 \times 10^4)(3.2 \times 10^{-2}) \div (8 \times 10^5)\\\frac{4 \times 3.2 \times 10^{4-2}}{8 \times 10^5}\\=1.6 \times 10^{2-5}\\=1.6 \times 10^{-3}

Barry's final score is 45 which player had the greater final score?
natali 33 [55]

The player with the greater final score is of:

Barry.

<h3>How to obtain which player had the greater final score?</h3>

Barry's final score is given as follows:

45.

Then we have to obtain Lee's score, from the description given in the missing information section.

Lee's scored is obtained as follows:

  • Starts at -350.
  • Answers a 275-point question correctly, hence - 350 + 275 = -75.
  • Answers a 70 - point question correctly, hence -75 + 70 = -5.
  • Answers a 50 - point question incorrectly, hence: -5 - 50 = -55.

Thus Lee's final score is given as follows:

-55.

The classifications of the final scores according to the signals are given as follows:

  • Barry: positive score.
  • Lee: negative score.

A positive score will always be greater than a negative score, hence Barry had the greater final score.

<h3>Missing information</h3>

Lee and Barry play a trivia game in which questions are worth different numbers of points. If a question is answered correctly, a player earns points. If a question is answered incorrectly, the player loses points. Lee currently has -350 points.

a. Before the game ends, Lee answers a 275 -point question correctly, a 70 -point question correctly, and a 50 -polnt question incorrectly. Write and find the value of an expression to find Lee's final score.

b. Barry's final score is 45. Which player had the greater final score?

Answer:

Point-Slope: y+1=-5/7(x-5)

Slope Intercept: y=-5/7x+ 2 4/7

Standard: -5x+7y=18

Step-by-step explanation:

<u>Slope: -5/7</u>

Point slope is when the equation is in y-y1=m(x-x1) form.

I used the point (5,-1) but it really <u>doesn't matter</u> which one

Substitute it into (x1,y1)

y--1=-5/7(x-5)

y+1=-5/7(x-5) **2 minus signs is equal to 1 plus sign**

Slope-intercept is when the equation is in y=mx+b form.

y=-5/7x+b

To solve for b, plug in one of the points (again, I choose to use (5,-1)

(-1)=-5/7(5)+b

-1=-25/7+b is equal to asking -1=-3 4/7+b

b=2 4/7

Standard form is when it is in Ax+By=C

We'll covert from slope intercept to standard: y=-5/7+ 2 4/7

y=-5/7x+ 2 4/7 is the same as y=(-5/7x+ 18/7)

7y=5x+18 **Multiply both sides by 7, the common denominators**

-5x+7y=18 **Subtract 5x from both sides**

<em>Sorry it took it while to get everything down but I hope this helps~</em>

Pls help math people
BartSMP [9]

Answer:

1. the range is the biggest number minus the smallest number.

2. for IQR order the data in ascending order, find the median, calculate the median for both the upper and lower halves of the data and the IQR is the difference between the two.

3. MAD is when you find the mean then add all the data values together and divide by the amount of data you have. Lastly, do the data value minus the mean.

Step-by-step explanation:

hope this helps :)

If tan fº = 2/1 and the measure of yw is 8 units, what is the measure of xw?
erma4kov [3.2K]

*see attachment for the figure referred to

Answer:

4 units

Step-by-step explanation:

Given that tan(f) = \frac{2}{1}, therefore, it follows that:

tan(f) = \frac{opp}{adjacent} = \frac{YW}{XW} = \frac{8}{XW},

If the ratio of YW to XW = 2:1, therefore, \frac{2}{1} = \frac{8}{XW}

Cross multiply to find XW

XW*2 = 8*1

XW = \frac{8}{2} = 4 units
