Answer 1

Answer:

Answer:

1479 g

Step-by-step explanation:

The volume of the bar is

V = l*w*h

= 10*3*5

= 150 cm^3

Now multiply by the density

150 cm^3 * 9.86 g/ cm^3 =1479 g

$\huge\text{Hey there!}$

$\huge\textbf{Equation:}$

$\mathsf{(3)/(4)a > -16}$

$\huge\textbf{Simplifying it:}$

$\mathsf{(3)/(4)a > -16}$

$\mathsf{(3)/(4)a > - (16)/(1)}$

$\huge\textbf{Divide \boxed{(4)/(3)} to both sides:}$

$\mathsf{(4)/(3)*(3)/(4)a > -16*(4)/(3)}$

$\huge\textbf{Simplify it:}$

$\mathsf{a > (4)/(3)* -16}$

$\mathsf{a > - (16)/(1) *(4)/(3)}$

$\mathsf{a > (-16*4)/(1*3)}$

$\mathsf{a > (-64)/(3)}$

$\mathsf{a > -(64)/(3)}$

$\mathsf{a > -21 (1)/(3)}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{- \frak{21(1)/(3)}}\huge\checkmark$

The data set shows the number of practice free throws players in a basketball competition made and the number of free throws they made in a timed competition.Practice throws 312 614 2 710 8Free throws 10 22 9 35 4 11 28 20A. Use technology to find the equation AND coefficient of determination for each type of regression model. Use the number of practice throws for the input variable and the number of free throws for the output variable. Round all decimal values to three places. Equation of regression modelCoefficient of determinationLinear model Quadratic model Exponential model B. EXPLAIN, using the information you found above, which model best fits the data set. How did you come to your conclusion?Note: write exponents like this x^2 if you need to.

Answers

Let

x -----> number of practice throws

y -----> the number of free throws

Part A

Linear Model

Using a Linear Regression Calculator

we have

ŷ = 2.352X - 0.852

see the attached figure

Remember that

With linear regression, the coefficient of determination is equal to the square of the correlation between the x and y variables

the coefficient r=0.919

Quadratic model

Using a Quadratic regression Calculator

we have

y=0.073x^2+1.205x+2.555

correlation coefficient r=0.925 ------> strong correlation

see the attached figure

Exponential model

Using an Exponential Regression Calculator

we have

y=4.229(1.17)^x

Correlation:r=0.913

see the attached figure

Part B

The model that best fits the data is the Quadratic model because its value of r is greater than the linear model and greater than the exponential model

Answer:

24 crates

Step-by-step explanation:

The usable load capacity for 40-kg crates is ...

1050 kg - 82 kg = 968 kg

The number of 40-kg crates that can be loaded in a trailer with this capacity is ...

floor(968/40) = floor(24.2) = 24 . . . . crates

_____

The function floor(n) gives the greatest integer less than or equal to n. For positive numbers, it drops the fraction.
