Answer: 7. g = -50, 8. f= 340/6 9. 3 10 .125

Step-by-step explanation:#7 g(3): 4(3)^2 +6 =12^2 +6 = 1444=6= 150. We divide 150 by 3 giving us -50.  #8We start by putting f(6): -3(6)^2 -4(6) +8. We use PEMDAS. -18^2 -24 +8 = _324-24+8 F= 340/6 #9 g(15) = Square root of 15-6=9 and the square root of 9 is 3, therefore, the answer is 3. #10 h (x) = 2^x we plug -3 to 2^-3. It is a negative number and it gives us .125 or 12.5

  • Answer:

<em />

<em>7. g(3) = 42</em>

<em>8. f(6) = - 124</em>

<em>9. g(15) = 3</em>

<em>10. h(-3) = 1/8</em>

  • Step-by-step explanation:

<em></em>

<em>7.</em><em> g(x) = 4x² + 6</em>

<em>g(3) = 4×3² + 6</em>

<em>= 4×9 + 6</em>

<em>= 36 + 6</em>

<em>= 42</em>

<em />

<em>8.</em><em> f(x) = - 3x² - 4x + 8</em>

<em>f(6) = - 3×6² - 4×6 + 8</em>

<em>= - 3×36 - 24 + 8</em>

<em>= - 108 -16</em>

<em>= - 124</em>

<em />

<em>9. </em><em>g(x) = √(x - 6)</em>

<em>g(15) = √(15 - 6)</em>

<em>= √9</em>

<em>= 3</em>

<em />

<em>10. </em><em>h(x) = 2ˣ</em>

<em>h(-3) = 2⁻³</em>

<em>= 1/2³</em>

<em>= 1/8</em>

An ornithologist has 4 bird feeders at separate locations. She wonders if birds are equally likely to visit each of the feeders.
Marianna [84]

Answer:

the x² test statistic 13.71

Option a) 13.71 is the correct answer.

Step-by-step explanation:

Given the data in the question;

Feeder                     1      2      3       4

Observed visits; o_i  60   90   92    58

data sample = 300

Expected e_i = 300 / 4 = 75

the x² test statistic = ?

X^2_{stat = ∑[ (o_i - e_i)²/e_i]

X^2_{stat = [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]

X^2_{stat = [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]

X^2_{stat = 13.7066 ≈ 13.71

Therefore, the x² test statistic 13.71

Option a) 13.71 is the correct answer.

Which expression is a difference of squares with a factor of 2x + 5? 4x2 + 10 4x2 – 10 4x2 + 25 4x2 – 25
Shtirlitz [24]

Answer:

  4x^2 -25

Step-by-step explanation:

The other factor of the difference of squares is the "conjugate" of the given one: (2x -5). Then their product is ...

  (2x +5)(2x -5) = (2x)^2 -(5)^2 = 4x^2 -25

Find the value of x in the isosceles triangle shown below
RUDIKE [14]
The answer is X= 5. Using the pythagorean theorem, and assuming that "b" is 3, half of 6 because the triangle is isosceles, you can solve the problem.

Since you are given that the student registered early, the total number you deal with is all students who registered early.

211 + 329 = 540

number of undergraduates who registered early = 211

Among students who registered early:

p(undergraduate) = 211/540
