Solve for x, show your work: 3/5 =x/30

Tpy6a [65]

Answer:

$\frac{3}{5} = \frac{18}{30}$

Step-by-step explanation:

To solve this proportion, we will divide the two given denominators.

Now, we have: 30 ÷ 5 = 6

Next, we will multiply the given numerator by the quotient: 3 × 6 = 18

So, our final proportion will have to be:

$\frac{3}{5} = \frac{18}{30}$

9x^2 + 24x + 20 = 4 Solve this by factoring. Thank you!

boyakko [2]

Note that,

$9x^2+24x+20=4\Longrightarrow9x^2+24x+16$

Which factors to,

$(3x+4)^2=0\Longrightarrow3x+4=0$

And simplifies to solution C,

$\boxed{x=-\dfrac{4}{3}}$

Hope this helps.

Any additional questions please feel free to ask.

A random sample is selected from a population with mean μ = 100 and standard deviation σ = 10. Determine the mean and standard d

Scilla [17]

Answer:

a) $\mu = 100, s = 3.015$

b) $\mu = 100, s = 2.425$

c) $\mu = 100, s = 1.581$

d) $\mu = 100, s = 1.348$

e) $\mu = 100, s = 0.477$

f) $\mu = 100, s = 0.953$

Step-by-step explanation:

The mean is the same no matter the size of the sample.

The standard deviation of the sample is the standard deviation of population divided by the square root of the length of the sample.

So:

(a) n = 11

$\mu = 100$

$s = \frac{10}{\sqrt{11}} = 3.015$

(a) n = 17

$\mu = 100$

$s = \frac{10}{\sqrt{17}} = 2.425$

(c) n = 40

$\mu = 100$

$s = \frac{10}{\sqrt{40}} = 1.581$

(d) n = 55

$\mu = 100$

$s = \frac{10}{\sqrt{55}} = 1.348$

(e) n = 440

$\mu = 100$

$s = \frac{10}{\sqrt{440}} = 0.477$

(f) n = 110

$\mu = 100$

$s = \frac{10}{\sqrt{110}} = 0.953$
