What is the value of |5| - 4(3²

harry rides his bike 25 3/8 miles Karen rides her bike 25 2/5 miles who rides farther explain each step to get brainiest answer

mote1985 [20]

The answer is going to be 25 2/5.
Steps i used to get the answer
I compared 25 3/8 and 25 2/5. I made the fractions into common denominators. so that would be 40. so i change the fractions which it would look like this 25 15/40 and 25 16/40. So now you compare 25 16/40 would be greater than 25 15/40. hope that helped

Which equation would best help solve the following problem? Hideki throws a baseball ball upward with an initial velocity of 12

Digiron [165]

The total time of flight of a projectile motion is calculated through the equation,
t = 2v₀sinФ/g
Substituting the known values,
t = (2)(12 m/s)(sin 90)/9.8 m/s²
t = 2.45 s
Thus, the total flight time of the ball in the atmosphere is 2.45 s.

A professor would like to test the hypothesis that the average number of minutes that a student needs to complete a statistics e

professor190 [17]

Answer:

$\chi^2 =\frac{15-1}{25} 16 =8.96$

The degrees of freedom are given by:

$df = n-1 = 15-1=14$

The p value for this case would be given by:

$p_v =P(\chi^2$

Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes

Step-by-step explanation:

Information given

$n=15$ represent the sample size

$\alpha=0.05$ represent the confidence level

$s^2 =16$ represent the sample variance

$\sigma^2_0 =25$ represent the value that we want to verify

System of hypothesis

We want to test if the true deviation for this case is lesss than 5minutes, so the system of hypothesis would be:

Null Hypothesis: $\sigma^2 \geq 25$

Alternative hypothesis: $\sigma^2$

The statistic is given by:

$\chi^2 =\frac{n-1}{\sigma^2_0} s^2$

And replacing we got:

$\chi^2 =\frac{15-1}{25} 16 =8.96$

The degrees of freedom are given by:

$df = n-1 = 15-1=14$

The p value for this case would be given by:

$p_v =P(\chi^2$

Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes
