Answer:

Step-by-step explanation:

A die has sides 1,2,3,4,5,6

There is no number greater than 6

P(number greater than 6) = number of numbers greater than 6/ total

= 0/6

= 0

Answer:

The probability is 0

Step-by-step explanation:

if it is a 6 sided die you can't roll higher than 6 other than itself but unless it is 6 or higher which it isnt

Analysis of an accident scene indicates a car was traveling at a velocity of 69.5 mph (31.1 m/s) along the positive x-axis at th

STatiana [176]

We can find the acceleration via

${v_f}^2-{v_i}^2=2a\Delta x$

We have

$\left(5.20\dfrac{\rm m}{\rm s}\right)^2-\left(31.1\dfrac{\rm m}{\rm s}\right)^2=2a(115\,\mathrm m)$

$\implies\boxed{a=-4.09\dfrac{\rm m}{\mathrm s^2}}$

Then by definition of average acceleration,

$a_{\rm ave}=\dfrac{v_f-v_i}t$

so that

$-4.09\dfrac{\rm m}{\mathrm s^2}=\dfrac{5.20\frac{\rm m}{\rm s}-31.1\frac{\rm m}{\rm s}}t$

$\implies\boxed{t=6.33\,\mathrm s}$

We alternatively could have found the time without knowing the acceleration. Since acceleration is constant, the average velocity is

$v_{\rm ave}=\dfrac{x_f-x_i}t=\dfrac{v_f+v_i}2$

Then

$\dfrac{115\,\rm m}t=\dfrac{5.20\frac{\rm m}{\rm s}+31.1\frac{\rm m}{\rm s}}2$

$\implies\boxed{t=6.33\,\mathrm s}$

If the coefficient of correlation is .8, then the percentage of variation in the dependent variable explained by the estimated r

Olegator [25]

Answer:

64%

Step-by-step explanation:

The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:

First, square the coefficient of correlation: 0.8^2 = 0.64

And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%
