Find the mean of 7, 9, 6, 15, 22, 25, 31. Round to the nearest whole number.
nexus9112 [7]
Add all the numbers and divide it by the number of numbers --> (7+9+6+15+22+25+31) = 115
115/7 = 16.4 --> conventional rounding would mean the answer would be 16

OLga [1]

Answer:

1) 10.55%

2) 30.77%

Step-by-step explanation:

52/52•39/51•26/50•13/49 = 0.105498... ≈ 10.55%

100% chance you draw a unique card on the first draw

51 cards left of which 13(3) = 39 are unique suit for your second draw

50 cards left of which 13(2) = 26 are unique suit for your third draw

49 cards left of which 13(1) = 13 are unique suit for your forth draw.

Two balls are already green

Leaves 4 red balls in a field of 13 balls

4/13 = 0.307692... ≈ 30.77%

HELP PLEASE ASAP IM SO CONFUSED!!!!!!!!
liubo4ka [24]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

We have the points (-4, -6) and (2, 6). Substitute:

m=\dfrac{6-(-6)}{2-(-4)}=\dfrac{12}{6}=2\\\\y=2x+b

Put the coordinates of the point (2, 6) to the equation of a line:

6=2(2)+b\\\\6=4+b\qquad|-4\\\\2=b\to b=2

<h3>Answer: y = 2x + 2</h3>

ASAP!!! Which of these graphs could represent an exponential <br> relation (Explain)
Margarita [4]

Answer:

B. looks like the best answer that fits this question.

If i'm wrong then my fault.

Step-by-step explanation:

When looking at choice (B) you can see it started at a decreasing point but slowly growing. Exponential relations are images or equations that describe growth and they always have the same function. If you look at the other choices you see that they either increase but then decrease or they don't match the formula for (exponential relations).

That's as good as I can do I dont knw if this what ur teacher is looking for but I tried :/
