Answer:

1. 2.50 dollars

2. 0.2 pounds

Step-by-step explanation:

Sorry if I explain things you might not understand.

1. To find how much one pound is, you solve the equation 2 / 5 = 1 / P. You solve for P which will be 2.5 or 5/2

2/5 = 1/P

2/5 x P x 5/2 = 1 / P x P x 5/2

P = 5/2

2. To find the amount of pounds per dollar, you solve the equation 5/2 = 1/D. You solve for D which will be 2/5 or 0.2 dollars.

5/2 x D x 2/5 = 1/D x D x 2/5

D = 2/5

Answer:

1. $2.5

2. 2/5lb

Step-by-step explanation:

1. The blank is asking what the cost of one pound of blueberries costs and you know that two pounds costs $5, so half of 5 is 2.5. So the first blank is $2.5.

2. You know that $2.5 will get you one pound, so divide by 5 and now you know that $0.50 will get you 1/5 pound of blueberries. multiply by two and now you know that $1.00 get you 2/5 pound of berries. So the second blank is 2/5 lb.

Arrange from least to greatest, 4.3, 5.5, 6 1/6, 15/4, 4 3/8?

Sophie [7]

Here are the numbers
4.3 , 5.5 , 6 $\frac{1}{6}$ , $\frac{15}{4}$ , 4 $\frac{3}{8}$
I'm going to change them into fractions
In the fractions, divide the numerator by the denominator
$6\frac{1}{6}$ ⇔6.1666---
$\frac{15}{4}$ ⇔3.75
$4 \frac{3}{8}$ ⇔4.375
Now to arrange them from least to the greatest
$\frac{15}{4}$ , 4.3 , $4 \frac{3}{8}$ , 5.5 , $6\frac{1}{6}$

Dennis can walk 2.833 miles each hour . About how far can he walk in 3 hours and 15 minutes

Bezzdna [24]

well, let's split the hours in minutes, so since 1 hr is 60 minutes, so he can walk 2.833 miles in 60 minutes, well, 3 hrs is 3*60 = 180 minutes, then we add 15 minutes, that's 195 minutes.

if he can walk 2.833 miles in 60 minutes, how long will it be for 195 minutes?

$\bf \begin{array}{ccll} miles&minutes\\ \cline{1-2} 2.833&60\\ x&195 \end{array}\implies \cfrac{2.833}{x}=\cfrac{60}{195}\implies \cfrac{2.833}{x}=\cfrac{4}{13} \\\\\\ 36.829=4x\implies \cfrac{36.829}{4}=x\implies 9.20725 = x$

The computer regression output includes the R-squared values, and adjusted R-squared values as well as other important values

a) The equation of the least-squares regression line is $\underline {\hat y = 235 \cdot x + 10835}$

b) The correlation coefficient for the sample is approximately 0.351

c) The slope gives the increase in the attendance per increase in wins

Reasons:

a) From the computer regression output, we have;

The y-intercept and the slope are given in the Coef column

The y-intercept = 10835

The slope = 235

The equation of the least-squares regression line is therefore

$\underline {\hat y = 235 \cdot x + 10835}$

b) The square of the correlation coefficient, is given in the table as R-sq = 12.29% = 0.1229

Therefore, the correlation coefficient, r = √(0.1229) ≈ 0.351

The correlation coefficient for the sample, r ≈ 0.351

c) The slope of the least squares regression line indicates that as the number of attending increases by 235 for each increase in wins
