Mathematics

The easiest way to make .15 a fraction would be to put 100 under it, making it 15/100.

But now it needs to be simplified. Find a number that goes into both the numerator and the denominator easily. In this case we can say 5.

Divide both numbers by 5:

15/5 = 3

100/5 = 20

Now our numerator is 3, while our denominator is 20, making your answer 3/20

Carisoprodol, a generic muscle relaxer, claims to have, on average, at least 120 milligrams of active ingredient. An independent

katovenus [111]

Answer:

The approximate p-value for the suitable test

0.05

|t| = |-1.5806| = 1.5806

t = 1.5806 < 2.009 at 0.05 level of significance

Carisoprodol, a generic muscle relaxer, claims to have, on average, is equal to 120 milligrams of active ingredient.

Step-by-step explanation:

Step(i):-

Given mean of the Population 'μ' = 120 milligrams

Given random sample size 'n' = 50

Given mean of the sample x⁻ = 116.2 milligrams

Standard deviation of the sample 'S' = 17 milligrams

Null hypothesis : 'μ' = 120

Alternative hypothesis : 'μ' < 120

Step(ii):-

Test statistic

$t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{116.2 - 120}{\frac{17}{\sqrt{50} } } = \frac{-3.8}{2.404} = -1.5806$

Degrees of freedom

ν = n-1 = 50 -1 =49

t₀.₀₅ = 2.009

|t| = |-1.5806| = 1.5806

t = 1.5806 < 2.009 at 0.05 level of significance

Null hypothesis is accepted

Carisoprodol, a generic muscle relaxer, claims to have, on average, is equal to 120 milligrams of active ingredient.

P- value:-

The test statistic |t| = 1.5806 at 49 degrees of freedom

The test statistic value is lies between 0.05 to 0.1

6+b/b is an integer number. find all possible integer values of b

Andrei [34K]

Step-by-step explanation:

(6+b)/b = x (= an integer number)

6 + b = bx (= still an integer number)

6 = bx - b = b(x - 1) (= still an integer number)

b = 6/(x - 1) (= still an integer number)

now for b to be integer, (x-1) must be a factor of 6 (6 must be divisible by x-1 with 0 remainder).

and integer includes negative numbers too.

the factors of 6 are therefore

1, 2, 3, 6, -1, -2, -3, -6

so, b can be 6/±1 = ±6

b can be 6/±2 = ±3

b can be 6/±3 = ±2

b can be 6/±6 = ±1

so, all possible values for b are also the listed factors of 6 :

-6, -3, -2, -1, 1, 2, 3, 6

Select all the ratios equivalent to 8:6. A. 4:3 B. 6:8 C. 16:12 D. 10:8 E. 7:5

omeli [17]

9514 1404 393

Answer:

A, C

Step-by-step explanation:

The given ratio can be reduced by removing a factor of 2 from each element.

8 : 6 = 4 : 3 . . . . matches A

It can be put in other forms by multiplying each element by the same factor. Using a factor of 2 on the original ratio values, we get ...

8 : 6 = 16 : 12 . . matches C

Any ratio that doesn't reduce to the integer ratio 4 : 3 is not equivalent. The ratio with elements reversed (3:4) is not equivalent.

56. Suppose you wish to make a scale drawing of your living room,

Deffense [45]

Answer: $8.33\ in$

Step-by-step explanation:

You know that the longer side of your living room is 25 feet and the shorter side of your living room is 18 feet.

Then, knowing that in the scale drawing the shorter side is 6 inches, you can say that the scale factor is:

$scale\ factor=\frac{18}{6}\\\\scale\ factor=3$

Let be "x" the longer side of the scale drawing in inches.

In order to find it, you must divide the actual longer side of you living room by the scale factor calculated above. Then you get:

$x=\frac{25}{3}\\\\x=8.33\ in$
