3(2x-5)=6x-15

3(2x-5) :

6x-15 = 6x-15

add 15 to both sides:

6x-15+15=6x-15+15

6x =6x

subtract 6x from  both sides:

6x-6x=6x-6x

0=0

Both sides are equal : true  for all x

Answer D

The computation of the data shows that the standard error is 0.015.

<h3>How to calculate the standard error?</h3>

From the information, the following can be deduced:

Number of students n = 49

Randomly selected students = 0.794

The standard error will be:

= 0.105/✓49

= 0.105/7

= 0.015

In conclusion, the standard error is 0.015.

Sam takes 1/3 hour to walk 1 km. he walks at the same rate. how many km will he walk in 4/5 of an hour
chubhunter [2.5K]
Speed of Sam = Distance / Time
Here, Distance = 1 Km
Time = 1/3 hour

Substitute the values, in the formula:
Speed = 1 / 1/3 = 3 Km/h

Now, In next situation, Speed = 3 Km/h
& Time = 4/5 hour.

Substitute the values, in the same formula:
Distance = Speed × Time
D = 3 * 4/5
D = 12/5 = 2.4 Km

In short, Final answer of your question would be 2.4 Km

Hope this helps!

saveliy_v [14]

Answer:

Yes

Step-by-step explanation:

Given that in the June 2007 issue, Consumer Reports also examined the relative merits of top-loading and front-loading washing machines, testing samples of several different brands of each type.

The difference in mean values test gave a p value of 0.32

Confidence level = 95%

Alpha = 1-0.95 = 0.05

Compare p with alpha, here p >alpha

Hence we accept null hypothesis that there is no difference in the means.

Confidence interval method also will yield the same result.  i.e. confidence interval for difference of means would definitely contain 0 at 95% conf level.

So answer is yes
