Answer:

$\frac{3}{25}$

Step-by-step explanation:

Given that $\overline{0.12}$ is the repeating decimal.

The repeating decimal $\overline{0.12}$ is converted into the fraction as :

$\overline{0.12} = \frac{3}{x}$

<=> 0.121212 = $\frac{3}{x}$

Multiplying both sides by x, we have,

<=> 0.121212x = 3

Dividing both sides by 0.121212, we get:

<=> x = $\frac{3}{0.121212}$

<=> x = 25

So the fraction represents the decimal $\overline{0.12}$ is: $\frac{3}{25}$

Hope it well find you well.

Select all the values that belong to the solution set of 9 ≤ 6 - y.

Veseljchak [2.6K]

All you have to do is substitute the values in for y to see if they are true.

0: 9 ≤ 6 - 0 = 9 ≤ 6 (FALSE)
3: 9 ≤ 6 - 3 = 9 ≤ 3 (FALSE)
-3: 9 ≤ 6 - -3 = 9 ≤ 9 (TRUE)
-1: 9 ≤ 6 - -1 = 9 ≤ 7 (FALSE)
-6: 9 ≤ 6 - -6 = 9 ≤ 12 (TRUE)
6: 9 ≤ 6 - 6 = 9 ≤ 0 (FALSE)
-4: 9 ≤ 6 - -4 = 9 ≤ 10 (TRUE)

So, the values that belong to 9 ≤ 6 - y are -3, -4, and -6.

Answer:

The Mean is not equal to $31,129.

Step-by-step explanation:

Consider the provided information.

The mean is $31129

Thus, the null hypothesis $H_0: \mu = 31129$

Alternative hypothesis $H_a: \mu \neq 31129$

A random sample of 15 firstyear CMAs in Denver produces a mean salary of $32,279, with a standard deviation of $1,797.

Thus the value mean of sample is 32279, standard deviation is 1797 and number of samples are 15.

Now use the 2 sided t-test.

$t=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

Now substitute the respective values in the above formula.

$t=\frac{32279-31129}{\frac{1797}{\sqrt{15}}}$

$t=\frac{1150}{464}$

Test Value = 2.4785 approximately

Now, find the corresponding p-value in your t-table with DF(degree of freedom) 14.

p = 0.0265

as the value of p < 0.05, so you reject null hypothesis.

Thus, the Mean is not equal to $31,129.

A landscaper wants to create a 12-foot-long diagonal path through a rectangular garden. The width of the garden is x feet and th

nasty-shy [4]

If we let x be the width of the garden, then x+4 will be the length. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs.

12² = (x)² + (x + 4)²

Simplifying,

144 = x² + x² + 8x + 16

Further simplification,

144 = 2x² + 8x + 16

x² + 4x - 128 = 0

The value of x from the equation is 6.2 ft. The length is then equal to 10.2 ft.

The answer to this item is the second choice.

Five friends have access to a chat room. Is it possible to determine who is chattingif the following information is known? Eithe

fenix001 [56]

Answer:

Kevin and Vijay are chatting

Step-by-step explanation:

Consider: Kevin=k

Heather=h

Randyor=v

Vijay=v

Abby=a

The values or the variables can be =o if they are not chatting and =1 if they arre chatting, then:

k+h>=1

v+r=1

a=r

v=k

if h=1 then a=1 and k=1, then as a=r, r=1 and as v=k, v=1, but then v+r=2, which is not possible because v+r=, then we can fisrt conclude than h=0.

.As k+h>=1, and h=0, then k=1. As k=v, then v=1.

As v+r=1, and v=1, then r=0. As r=a, a=0

So in conclusion, a=0, r=0, v=1, k=1 and h=0, so Kevin and Vijay are chatting
