group of people = p

There are 8 in one group: 8p

There are 96 people in all

p/8; 12 should be your answer (p/8, because total # of people/amount in each; 12, because of the amount of groups there is.)

hope this helps

In each group, there are 8 people. For p groups, multiply by 8

$8 \times p = 8p$

Remember that in each group, there are 8 people. In this case, there are 96 people. Divide 96 by 8 to find the amount of groups formed:

$96 \div 8 = 12$

12 groups

The last choice matches the answer. Your answer is the last choice.

F(x)=3x−4g(x)=−x2+2x−5h(x)=2x2+1j(x)=6x2−8xk(x)=3x2−x+7 Calculate (fh)(x).

elena-s [515]

Answer:

( f h ) (x) = 6 x² - 1

Step-by-step explanation:

Step(i):-

Given f(x) = 3 x - 4

g (x) = −x²+2 x−5

h (x) = 2 x² + 1

j (x) = 6 x + 2 - 8 x

K (x) = 3 x² - x + 7

Step(ii):-

( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )

= 3 (2 x² + 1 ) - 4

= 3 ((2 x² ) + 3 - 4

= 6 x² - 1

Final answer:-

∴ ( f h ) (x) = 6 x² - 1

TrianglesABC and DEF are Similar Not similar

puteri [66]

Answer:

Similar

Step-by-step explanation:

We can say that the triangles are similar by looking at the angle measurements

Angle B = 35

Angle F = 55

Both angles A and D = 90 because these are right triangles

We can say the measure of angle E = 35 because the sum of angles in a triangle equal to 180

Same rule applies to angle C

Unknown to a medical researcher, 6 out of 25 patients have a heart problem that will result in death if they receive the test dr

Fiesta28 [93]

Using the hypergeometric distribution, it is found that there is a 0.0002 = 0.02% probability that exactly 6 patients will die.

<h3>What is the hypergeometric distribution formula?</h3>

The formula is:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

The values of the parameters for this problem are:

N = 25, k = 6, n = 8.

The probability that exactly 6 patients will die is P(X = 6), hence:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$P(X = 6) = h(6,25,8,6) = \frac{C_{6,6}C_{19,2}}{C_{25,8}} = 0.0002$

0.0002 = 0.02% probability that exactly 6 patients will die.
