(x – 1)(x + 1)(x + 5) = 0

x – 1 = 0, so x = 1

x + 1 = 0, so x = -1

x + 5 = 0, so x = -5

Sarah Meeham blends coffee for Tasti-Delight. She needs to prepare 160 pounds of blended coffee beans selling for $4.97 per poun

jok3333 [9.3K]

Given:
let h be the high quality bean
let c be the cheaper bean

h + c = 160
6h + 3.25c = 160*4.97
6h + 3.25c = 795.20

h = 160 - c
6(160 - c) + 3.25c = 795.20
960 - 6c + 3.25c = 795.20
-2.75c = 795.20 - 960
-2.75c = -164.80
c = -164.80 / -2.75
c = 59.92 or 60 lbs

h = 160 - c
h = 160 - 60
h = 100 lbs

Sarah should blend 60 lbs of cheap coffee bean and 100 lbs of high quality coffee bean.

Suppose a simple random sample of size n = 1000 is obtained from a population whose size is N = 2,000,000 and whose population p

faltersainse [42]

Answer:

$p(x\geq 520) = 0.0293$

Step-by-step explanation:

Given data:

random sample size n = 1000

Population size is N - 2,000,000

P = 0.49

We know

$\sigma_p = \sqrt{\frac{p*(1-p)}{n}}$

$\sigma_ p = \sqrt{\frac{0.49*(1-0.49)}{1000}} = 0.0158$

Probability for having X =520

sample proportion $\hat p = \frac{520}{1000} = 0.52$

$p(x\geq 520) = P(\hat p\geq)$

$= P(Z\geq \frac{0.52 - 0.49}{0.0158})$

$= P(Z\geq 1.89) = 0.0293$

$p(x\geq 520) = 0.0293$
