If your asking if those lengths would form a triangle... then they won’t because if the two shortest side don’t add up to be larger then the largest side then they won’t make a triangle

Is this mapping a function or not a function explain

Alisiya [41]

Answer:

No. This isn’t a function.

Step-by-step explanation:

Ok, functions have x values that only have 1 y value. It doesn’t matter if the y values have multiple x values.

So, first look at the x values, all of them have 1 y value but the number 6. Therefore, this does not represent a function.

The answer is the 2nd one.

Gummi bears come in twelve flavors, and you have one of each flavor. Suppose you split your gummi bears among three people (Adam

aliina [53]

Step-by-step explanation:

From the given gummi bear, the chance that Adam is selected for any draw is 1/3 as well as the chance he is not selected at any draw is 2/3.

a). The probability of Adam getting exactly three gummi bears = P(Adam gets selected at 3 draws and not selected at the remaining 9 draws)

= $(\frac{1}{3})^3 (\frac{2}{3})^9 = \frac{2^9}{3^{12}}$

Now, the 3 draws where Adam gets selected can be any 3 out of 12 draws in ${\overset{12}C}_3$ = 220

Thus, probability of Adam getting three gummi bears = $220 \times \frac{2^9}{3^{12}}$

= 0.21186

b). Probability that Adam will get the three gummi bears given each person will received at the most 1 gummi bear

= P(of the remaining 9 draws after assigning one gummi bear to each one, Adam gets selected at 2 draws and not selected at 7 draws) = ${\overset{9}C}_2 (\frac{1}{3})^2 (\frac{2}{3})^7$

= 0.23411

c). Let X = Number of the gummi bears which Adam will get. Then, X = number of draws out of 12 draws Adam gets selected and X ~ B(12, 1/3). So, Adam will get gummi bears= mean of B(12, 1/3) = 12 x (1/3) = 4

d). Let Y = Number of the gummi bears that Adam will get, given each person will received at the most 1 gummi bear Then, Y = number of draws Adam gets selected in the remaining 9 draws and Y ~ B(9, 1/3). So, the expected number of bears that Adam gets given each person received at least 1 gummi bear

= 1 + mean of B(9, 1/3) = 4

e). When every one gets atleast one gummi bear, the new sample size will be 9 and so we can say that there is a reduction in variance.

Arlene had some blackberries. She gave 216 to her teachers. Then she dropped 12. Later, she ate 18. Finally, she gave half of wh

Bingel [31]

Answer:the number of BlackBerry that Arlene had initially was 276

Step-by-step explanation:

Let x represent the number of BlackBerry that Arlene had initially.

She gave 216 to her teachers. This means that she is left with x - 216

Then she dropped 12. This means that she would be left with x - 216 - 12 = x - 228

Later, she ate 18. This means that she would be left with x - 228 - 18 = x - 246

Finally, she gave half of what she had to her friend. This means that the amount that she gave to her friend is (x - 246)/2 and the amount that she has left would be

(x - 246)/2

Now, she has 15. This means that

(x - 246)/2 = 15

x - 246 = 2 × 15 = 30

x = 30 + 246 = 276

Anika [276]

Answer:

Austin earned a higher score

Step-by-step explanation:

47/50 (Austin's score) = 94/100 (denominator is now 100) = 94% (converted to percentage) > 92% (Marty's score)

Hope this helps!
