11/(x+9)=5<br> I am struggling with this question. Is there a solution?

maks197457 [2]

Answer:

x=-6.8

$\\ step \: by \: step \: explanation \\ \frac{11}{(x + 9)} = 5 \\ 11 = 5(x + 9) \\ 11 = 5x + 45 \\ 5x = 11 - 45 \\ 5x = - 34 \\ x = \frac{ - 34}{5} = - 6.8$

A survey found that the American family generates an average of 17.2 pounds of glass garbage trash each year. Assume the standar

SIZIF [17.4K]

Answer: 0.8137

Step-by-step explanation:

As per given , we have

$\mu= 17.2\ ,\ \sigma=2.5$

Sample size : n= 47

Let $\overline{X}$ be the sample mean o.

Then, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds will be :

$P(16.6$

$=P(-1.645$

[∵ $z= \dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$ ]

$=P(z$

$=0.8636793-(1- 0.9500151)$ [By using p-value calculator]

$=0.8636793-0.0499849=0.8136944\approx0.8137$

Hence, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds= 0.8137

How long does it take $500 to double at a simple interest rate of 24%?

yuradex [85]

Answer:

4 years and 2 months

Step-by-step explanation:

<u>Simple interest formula</u>

A = P(1 + rt)

where:

A = final amount
P = principal amount
r = interest rate (in decimal form)
t = time (in years)

Given:

A = $500 × 2 = $1,000
P = $500
r = 24% = 0.24

Substitute the given values into the formula and solve for t:

$\implies \sf 1000 = 500(1 + 0.24t)$

$\implies \sf \dfrac{1000}{500}=(1 + 0.24t)$

$\implies \sf 2=1 + 0.24t$

$\implies \sf 1 = 0.24t$

$\implies \sf t=\dfrac{1}{0.24}$

$\implies \sf t=4 \frac{1}{6} \:years$

$\implies \sf t=4\:years\:2\:months$

Therefore, it takes 4 years and 2 months for the initial investment of $500 to double at a simple interested rate of 24%.

Translate the following verbal expressions into

AleksAgata [21]

Answer:

16 + 4n

3(x - 8)

(5 × y) - 3

Step-by-step explanation:

16 increased by 4 times a number:

16 + 4n

Three times the difference of x and 8:

3(x - 8)

3 less than the product of 5 and y:

(5 × y) - 3
