13.) To solve, you make and equation for each problem, then you make them equal each other : 50h+75=65h. You have to have both variables in each side so you subtract 50h from both sides and are left with 75=15h. Then you just solve for h. h=5

Approximately 18% of the population of California is 70 years or older. In a random sample of 4, what is the provability for 3 o

Semmy [17]

Answer:

The correct response will be "0.01913".

Step-by-step explanation:

According to the question,

p - P(70 years or older)

= 0.18

n = 4

X = no. of individuals who are older than 70 years

Now,

∴ $P(X=r)=n_C_r \ p^r(1-p)^{n-r}$

∴ $P(X=3)=4_C_3(0.18)^3(1-0.18)^{4-3}$

$=4\times (0.18)^3(0.82)^1$

$=0.01913$

A merchant mixed 10 lb of a cinnamon tea with 2 lb of spice tea. The 12-pound mixture cost $13. A second mixture included 16 lb

Sonja [21]

Step-by-step explanation:

Let's say c is the price of cinnamon tea, and s is the price of spice tea.

10c + 2s = 13

16c + 8s = 28

Divide the second equation by 4:

4c + 2s = 7

Subtract from the first equation:

6c = 6

c = 1

Use any equation to find s.

s = 1.5

Therefore, the cinnamon tea costs $1 per pound and the spice tea costs $1.50 per pound.
