jeka57 [31]2 years ago
3 0

Answer:

(a) -7, (b) 2

Step-by-step explanation:

a) When x = 0,

=> x² - 8x - 7

=> (0)² - 8(0) - 7

=> 0 - 0 - 7

=> - 7

b) When x = -1,

=> x² - 8x - 7

=> (-1)² - 8(-1) - 7

=> 1 + 8 - 7

=> 9 - 7

=> 2

Is 5/6 closest to 0,1/2, and 1
Ne4ueva [31]
I think the answer is 1.First, find the least common denominator, which is 6. Then, multiply the numerator and denominator by the same number to get 6 as the denominator. \frac{0}{1} is multiplied by 6 to get \frac{0}{6}. \frac{1}{2} is multiplied by 3 to get \frac{3}{6}. \frac{1}{1} is multiplied by 6 to get \frac{6}{6}. Since \frac{5}{6} is closest to \frac{6}{6}, 1 is the answer. Hope this helps!

Finding values or<br> k(x) = x - 2<br> h(x) = x2 +1<br> (h + k)(2) =
Serjik [45]

Answer:

<h2>(h + k)(2) = 5</h2>

Step-by-step explanation:

(h+k)(x)=h(x)+k(x)\\\\\bold{METHOD\ 1:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(k+h)(2)=h(2)+k(2)\\\\\text{Calculate}\ h(2)\ \text{and}\ k(2).\\\text{Put}\ x=2\ \text{to the equations of the functions}\\\\h(2)=2^2+1=4+1=5\\k(2)=2-2=0\\\\\text\\\\\text{Substitute:}\\\\(h+k)(2)=5+0=5

\bold{METHOD\ 2:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(h+k)(x)=h(x)+k(x)=(x^2+1)+(x-2)=x^2+x-1\\\\(h+k)(2)-\text{put}\ x=2\\\\(h+k)(2)=2^2+2-1=4+2-1=6-1=5

2) The following table presents the probability distribution of the number of vacations X taken last year for a randomly chosen
algol [13]

The mean of the discrete probability distribution is of 1.28.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

Then, considering the given distribution, the mean is given by:

E(X) = 0(0.13) + 1(0.61) + 2(0.15) + 3(0.07) + 4(0.04) = 1.28.
