Alex invests £3045 into an account that pays 2.25% compound interest per year.

Inessa [10]

<h2>○=> <u>Correct answer</u> :</h2>

Money in Alex's account after 16 years = $\boxed{\bold{\color{plum}£4347.11}}$

<h3>○=> <u>Steps to derive correct answer</u> :</h3>

Money invested by Alex = £3045

Percentage of compound interest per annum = 2.25%

We know that :

$\tt \: \color{hotpink}A \color{plum} = P {(1 + \frac{r}{n} )}^{nt}$

In this case :

Principal = £3045

Rate = 2.25% = 0.0025

Number of times interest is compounded per year = 1

Time = 16 years

Which means :

Money Alex will have in the account after 16 years :

$= \tt3045 ({1 + \frac{ 0.0025}{1} })^{16}$

$\color{plum}= \tt £4347.11$

Therefore, the money in Alex's account after 16 years = £4347.11

How to graph 3x=-6 show your work

katrin2010 [14]

Answer:

x=-2

Step-by-step explanation:

divide both sides by 3

you get x=-2

go to -2 on the x axis and draw a line straight down, x=-2 will intercept the x axis at the point -2

same thing for y=-5 (example)

go down five on the y axis and draw a horizontal line to the y axis intercepting at point (0,-5)

An elevator has a placard stating that the maximum capacity is 1610 lb---10 passengers. So, 10 adult male passengers can have a

Yuri [45]

Answer:

The probability is "0.6406", this elevator isn't appear to be safe

Step-by-step explanation:

The given values are:

Mean,

$\mu=165$

Standard deviation,

$\sigma=35$

Number of male passengers,

$n = 10$

Now,

⇒ $z=\frac{161-165}{\frac{\sigma}{\sqrt{10} } }$

$=\frac{161-165}{\frac{35}{\sqrt{10} } }$

hence,

The probability will be:

= $P(\bar {x}>161)$

= $P(z > -0.3614)$

= $0.6406$
