A grocery store will only accept yellow onions that are at least 2.75 in. In diameter. A grower has a crop of onions with diamet
Paraphin [41]

Answer:

Step-by-step explanation:

Calculate z-score firstly

z-score = (x-mean)/SD = (2.75-2.5)/0.25 = 0.25/0.25 = 1

P( x greater than or equal to 2.75) = P(z greater than or equal to 1)

= 1 - p(z <1)

P(z<1) from table = 0.84134

1-p(z<1) = 0.15866 or 15.866%

Enter your answer in the provided box. what is the emf of a cell consisting of a pb2 / pb half-cell and a pt / h / h2 half-cell
s2008m [1.1K]

The emf of a cell is mathematically given as

E_{cell}  = 0.0532 v

<h3>What is the emf of a cell?</h3>

Generally, the equation for emf  is mathematically given as

Pb/Pb^2^+ //\ H / H_2

where,

Pb is lead

H is hydrogen

Pb^{2+} / Pb has a standard reduction potential of -0.126 volts, while

H_2 / H_2 has a standard reduction potential of 0.0 volts.

E_{cell }= E^0_{cell} - 0.059/n log 1/[Pb^2^+] x [H^+]^2

E_{cell} = 0.126 -  0.059/2 log 1  /  [0.57] x [0.09]^2

E_{cell}  = 0.0532 v

(a+2b)² ?????????????????????<br>​
lbvjy [14]

Answer:

a² + 4ab + 4b²

Step-by-step explanation:

Given

(a + 2b)²

= (a + 2b)(a + 2b)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis

= a² + 2ab + 2ab + 4b² ← collect like terms

= a² + 4ab + 4b²

Donnell and Maria are both members of a populationand a simple random sample is being conducted. If the chance of Donnell being
harina [27]

Answer:

289/290

Step-by-step explanation:

Given that the chance of Donnell being selected is 1/290

then P( Donnell being selected )= 1/290

Since Donnell and Maria are both member of a population.

from probability theorem which gives the likely hood of an event to happen which cannot be more than 1, then the probability of Donnell and Maria to be selected is 1

P(Donnell and Maria)= 1

But the chance of Donnell being selected is 1/290

Then,

1/290 + P(Maria)= 1

P(Maria)= 1-(1/290)

= 289/290

the chance of Maria being selected is 289/290
