How much of a radioactive kind of bromine will be left after 140 hours if the half-life is 35 hours and you start with 864 grams?

Answers

Answer:

1, Because the half-life is 6 hours, the initial amount is halved every 6 hours. Due to the total of 18 hours, the starting amount will be divided by 2 (halved) three times. You will then have one-sixth of the original amount, which is 384 grams divided by six equals 48 grams.

Find the correlation coefficient for the data. Round to the nearest hundredth.

Answers

the correlation coefficient for Alfonso survey is 0.36.

What is the correlation coefficient?

The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.

For the given situation,

The table below shows the values of the data x, y and the correlation calculations.

The formula of correlation coefficient is

[tex]r=\frac{n(\Σ xy)-(\Σ x)(\Σ y)}{\sqrt{[n\Σ x^{2} -(\Σ x)^{2} }] [n\Σ y^{2}-(\Σ y)^{2} ]}[/tex]

From the table substitute all the values.

⇒ [tex]r=\frac{(11)(98-(37)(26))}{\sqrt{[11(153)-37^{2} ][(11)(92)-26^{2} ] }}[/tex]

⇒ [tex]r=\frac{1078-962}{\sqrt{(1683-1369)(1012-676)} }[/tex]

⇒ [tex]r=\frac{116}{\sqrt{(314)(336)} }[/tex]

⇒ [tex]r=\frac{116}{324.81}[/tex]

⇒ [tex]r=0.357[/tex] ≈ [tex]0.36[/tex]

Hence we can conclude that the correlation coefficient for Alfonso survey is 0.36.

Tyler bought shoes for $72. The next week he noticed that the price went
up to $87. What was the percent increase (percent change)? Round your
answer to the nearest whole percent. *

Answers

Answer:

Percent increase is 21%

Step-by-step explanation:

Initial cost of shoes = $72

New price of shoes = $87

Increase in price of shoes = New price of shoes - Initial cost of shoes

= [tex]87-72[/tex]

= $15

Percentage increase in price of shoes = ( Increase in price of shoes ÷ Initial cost of shoes) × 100

= [tex]\frac{15}{72}(100)=20.8\%[/tex]

≈ 21%

So, percent increase is 21%

Which equation represents the proportional relationship between the cost, t, in dollars, of p pounds of wood bought? T=0.29pt = 0.29 p t=0.31pt = 0.31 p t=3.45pt = 3.45 p t=3.48p

Answers

Answer:

T = 0.29p

Step-by-step explanation:

From the table Given :

We can obtain the uint cost per pound of wood :

Cost of 12 pounds of wood = $3.48

Cost per pound = Cost / weight

Cost per pound = $3.48 / 12 = $0.29

Hence, the proportional relationship cost, T in dollars and p pounds of wood is ;

Cost = unit cost per pound * number of pounds

T = 0.29 * p

T = 0.29p
