Which of the following table represents a function? Please help! Will make brainliest
OlgaM077 [116]

Answer:

Last one at the bottom

Step-by-step explanation:

Recall that for a function to be valid, each input (x-value) must give exactly one unique output (y-value). If we find that any x-value gives more than one y-value, then it is not a function.

Option 1: x = 3 gives y = 2 and y = -2 (not a function)

Option 2: x = 5 gives y = 2 and y = 8 (not a function)

Option 3: x = 3 gives y = 4 and y = 5 (not a function)

Option 4: each x-value gives only one possible y-value (this is a function)

Please help… Will mark brainliest!!!
Korolek [52]

Answer:

value of a is -19

value of b is 10

Step-by-step explanation:

<u>Given</u>

p(x) = 6x³ + ax² + 9x + b

Since it is given (x-2) & (2x-1) are the factors of given polynomial p(x) .

So, x = 2 & x = -1/2 are the solutions of given polynomial .

<u>when </u><u>x </u><u>=</u><u> </u><u>2</u><u> </u>

p(2) = 6(2)³ + a(2)² + 9 (2) + b = 0

p(2) = 6×8 + 4a + 18 + b = 0

p(2) = 48 + 4a + 18 + b = 0

p(2) = 66 + 4a + b = 0

4a + b = -66 -------(i)

Now ,

when x = -½

p(-½) = 6(-½)³ + a (-½)² + 9(-½) + b = 0

6 × (-⅛) + a/4 - 9/2 + b = 0

-3/4 + a/4 - 9/2 + b = 0

-3 + a -18+4b/4 = 0

-21 + a + 4b = 0

a + 4b = 21 -------(ii)

Now, multiplying the equation (ii) by 4 we get

4a + 16b = 84 -----(iii)

Substracting equation (i) from (iii) we obtain

15b = 150

b = 150/15

b = 10

Now, putting the value of b = 10 in equation (ii) we get

a + 40 = 21

a = 21-40

a = -19

So, the required value of a & b are 10 & -19 respectively .

A randomly selected sample of college basketball players has the following heights in inches.
Romashka [77]

Answer:

__63.81 inches__< μ <___65.87 inches__

Step-by-step explanation:

To calculate at 95% confidence interval, we need the Mean of the sample= 64.84

Sample size=32

Standard Deviation=2.9592

95% Confidence Interval: 64.84 ± 1.03

(63.81 inches to 65.87 inches)

"With 95% confidence the population mean is between 63.81 and 65.87, based on 32 samples."
