Answer:

The solution is (-6, 30)

Step-by-step explanation:

Here we have two separate equations for y and are to find the solution (x, y).

y = 2x + 42

y = -5x

First, equate y = 2x + 42  and y = -5x:

2x + 42  = -5x

Combining like terms, we get

7x = -42, which results in x = -6

Since y = -5x, y = -5(-6), or y = 30, when x = -6.

The solution is (-6, 30)

castortr0y [4]

Answer:

After 3 years, Sue will get £2471.70 and Bill will get £1993.28.

Step-by-step explanation:

Amount at Compound Interest, A=P(1+\frac{r}{k} )^{nk}

Since interest is compounded everyday, period, k=365.

<u>Sue</u>

Amount Invested, P=£2300

Interest Rate Per annum (Saver Account) = 2.4%=0.024

Period, k=365 days

Number of Years, n=3 years

A=2300(1+\frac{0.024}{365} )^{365*3}\\=\£2471.70

<u>Bill</u>

Amount Invested, P=£1800

Interest Rate Per annum (1234 Account ) = 3.4%=0.0034

Period, k=365 days

Number of Years, n=3 years

A=1800(1+\frac{0.034}{365} )^{365*3}\\=\£1993.28

<u>After 3 years, Sue will get £2471.70 and Bill will get £1993.28.</u>

The lengths of pregnancies in a small rural village are normally distributed with a mean of 261 days and a standard deviation of
valina [46]

Answer:

(221.39, 300.61) and (255.2223, 266.7777)

Step-by-step explanation:

Given that X, the  lengths of pregnancies in a small rural village are normally distributed with a mean of 261 days and a standard deviation of 17 days

Middle 98% would lie on either side of the mean with probability ±2.33 in the std normal distribution on either side of 0

Corresponding we have x scores as

Between 261-2.33*17 and 261+2.33*17

i.e. in the interval = (221.39, 300.61)

If sample size = 47, then std error of sample would be

\frac{17}{\sqrt{47} }

So 98% of pregnancies would lie between

261-2.33*\frac{17}{\sqrt{47} } and 262+2.33*\frac{17}{\sqrt{47} }

= (255.2223, 266.7777)
