A) -2, -1
(solve the second equation for x (subtract 2y to the other side, then divide by 2 so x=-y-3) then plug that equation into the x value of the first equation to get y=-1; plug y=-1 into the second equation to get x=-2)

What is the distance between the points (4, 3) and (1, -1) on the coordinate
Delvig [45]

The distance between the points (4, 3) and (1, -1) on the coordinate plane will be 5 units. Then the correct option is C.

<h3>What is the distance between two points?</h3>

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D² = (x - p)² + (y - q)²

The points are given below.

(4, 3) and (1, -1)

Then the distance between the points will be

D² = (4 - 1)² + (3 + 1)²

D² = 3² + 4²

D² = 9 + 16

D² = 25

D = 5 units

Then the correct option is C.

Using a calculator with the binompdf and binomcdf features, I can calculate these values. My calculator is a TI-83 plus, and the features are found under the 2nd, Vars keys (Scroll up or down until you see them).

If "exactly" is to be found, use binompdf: 
binompdf(number of trials, probability of success, exactly number)

ANSWER for exactly 3: binompdf(8, 0.5, 3) = 0.21875 = 21.875%

If "at least" is to be found, use binomcdf:
binomcdf(number of trials, probability of success, at least number - 1)

ANSWER for at least 6: binomcdf(8, 1/2, 5) ≈ 0.8555 ≈ 85.55%

If "at most" is to be found, use binomcdf:
binomcdf(number of trials, probability of success, at most number)

ANSWER for at most 3: binomcdf(8, 0.5, 3) ≈ 0.3633 ≈ 36.33%

2/3x - 7 &lt; 9 <br> help please
Andrew [12]

Answer:

x<24

*the answer will be incorrect if you meant 2/(3x) instead of (2/3)x

Step-by-step explanation:

First, add 7 to both sides of the inequality to get "2/3x<16." Then multiply both sides by 3 to get "2x<48." Finally, divide both sides by 2 to get "x<24"

I really need help with this question. I need this to be explained because I don't even understand what a 5-number summary is. T
OLEGan [10]
I did it on paper just now.  Sorry for the sloppy handwriting, but you should be able to answer the two questions with the info I got.  If you don't know what five number summary is, just google it.

Basically, arrange the list of numbers in order, and then find the minimum, 1st quartile, median, 3rd quartile, and maximum.
