Answer:

Sasha used 15 pieces of pineapple

Step-by-step explanation:

<u><em>The complete question is</em></u>

Sasha made a small pizza with four pieces of ham and five pieces of pineapple. He is making a large pizza with 12 pieces of ham using the same proportion of pineapple ham. How many pieces of pineapple did Sasha use?

Let

x ----> pieces of ham

y ----> pieces of pineapple

we know that

\frac{x}{y}=\frac{4}{5} ----> equation A

For x=12

substitute in the equation A and solve for y

\frac{12}{y}=\frac{4}{5}

y=12(5)/4\\y=15

therefore

Sasha used 15 pieces of pineapple

A recent article in the paper claims that business ethics are at an​ all-time low. Reporting on a recent​ sample, the paper clai
Savatey [412]

Answer:

P=0.3726 or 37.26%

Step-by-step explanation:

The success, with 41% of probability of occurring, is that the employee believes the ​ company's president possesses low ethical standards. For more than 8 and less than 12 successes, it means the probability of having  9, 10 or  11 successes (all these summed).

The formula is:

b(x;n,p)= \ _nC_x*p^x*(1-p)^{n-x}

Where x is the number of successes,n the number of trials, p the probability of success,_nC_x refers to the combinations that can occur,  and it's formula is:

_nC_x=\frac{n!}{x!(n-x)!}

Calculating each case:

b(9,20,0.41)=\frac{20!}{9!(20-9)!}*0.41^9*(1-0.41)^{20-9}=0.1658

b(10,20,0.41)=\frac{20!}{10!(20-10)!}*0.41^{10}*(1-0.41)^{20-10}=0.1267

b(11,20,0.41)=\frac{20!}{11!(20-11)!}*0.41^{11}*(1-0.41)^{20-11}=0.0801

Adding each case:

P=0.1658+0.1267+0.0801= 0.3726

A scientist begins with 250 grams of a radioactive substance. After 250 minutes, the sample has decayed to 32 grams. Rounding to
s2008m [1.1K]

Answer:

Part 1 : A=250 e^{-0.008223t}

Part 2 : Half life is 84 minutes ( approx )

Step-by-step explanation:

Part 1 : Suppose the function that shows the amount( in grams ) of the substance after t minutes,

A=A_0 e^{kt}

If t = 0 min, A = 250 grams,

250=A_0 e^{0}

\implies A_0 = 250

If t = 250, A = 32 grams,

32 = A_0 e^{250k}

32 = 250 e^{250k}

0.128 = e^{250k}

Taking ln both sides,

\ln(0.128) = 250k

\implies k =\frac{\ln(0.128)}{250}=-0.008223

Hence, the equation that shows this situation,

A=250 e^{-0.008223t}

Part 2 : If A = 250/2 = 125,

125 = 250 e^{-0.008223t}

0.5 = e^{-0.008223t}

Taking ln both sides,

\ln(0.5) = -0.008223t

\implies t =\frac{\ln(0.5)}{-0.008223}\approx 84

Therefore, the half life of the substance would be 84 minutes.
