Answer:

One of the equivalent expressions is 2(j+k).

Step-by-step explanation:

In the expression

j+j+2k

there are 2 j's ;therefore, the expression can be rewritten as

2j+2k,

and using the reverse distribute property which says

ax+ay=a(x+y),

we rewrite our expression as

2j+2k = \boxed{2(j+k).}

You would keep the 2 hour for the whole number of the mixed number and then, make the minutes (15) as a fraction with 60, and divide them both by 20. that is just for the mixed number.

The standard deviation of pulse rates of adult males is more than 11 bpm. For the random sample of 153 adult males the pulse rat
Alenkasestr [34]

Answer: 160.4040

Step-by-step explanation:

Here , the claim is "The standard deviation of pulse rates of adult males is more than 11 bpm." , i.e. \sigma>11

We use Chi-square test statistic for the test statistic to test the standard deviations :

\chi^2=\dfrac{(n-1)s^2}{\sigma^2} , where s= sample standard deviation , \sigma = population standard deviations and n = sample size.

As per given , n=153 , s= 11.3

Then, Required test statistic will be :

\chi^2=\dfrac{(153-1)(11.3)^2}{11^2}=\dfrac{152\times127.69}{121}\approx160.4040

Hence, the value of the test statistic. =  160.4040

Radda [10]

Answer:

  C.

Step-by-step explanation:

The function (f+g)(x) is the sum of the two functions:

  (f+g)(x) = f(x) +g(x) = (ln(2x) -15) +(3sin(x) -7)

  = ln(2x) +3sin(x) +(-15 -7)

  (f+g)(x) = ln(2x) +3sin(x) -22
