Nancy goes to the Post Office to exchange money.
Exchange Rates
£1:$1.31
£1 : €1.14
*Commission Charged
$ £ €
Nancy changes $759.80 and €342 into pounds sterling.
The Post Office deducts their commission and gives Nancy £827.20
What is the percentage commission?​

Answers

Answer:

6% commission

Step-by-step explanation:

Exchange Rates

£1:$1.31

£1 : €1.14

$759.80 to pounds sterling :

£1 = $1.31

x = $759.80

Cross multiply :

x = 759.80 / 1.31

x = £580

£1 = €1.14

x = €342

Cross multiply :

x = 342 /1.14

x = £300

Total = £(580 + 300) = £880

Amount deducted = commision = £880 - £827.20 = £52.80

Percentage commission :

(52.80 / 880) * 100%

0.06 * 100%

= 6% commission

Which is an example of a quadratic function whose graph opens downward and has its vertex at (0, 1)?

A. y = −x^2 + 1
B. y = x^2 + x − 1
C. y = x^2 + 4x + 1
D. y = x^2 − 1

Answers

Given:

The graph of a quadratic function opens downward and has its vertex at (0, 1).

To find:

The quadratic function.

Solution:

The vertex form of a quadratic function is:

[tex]y=a(x-h)^2+k[/tex]          ...(i)

Where, a is a constant and (h,k) is the vertex.

If a<0, then graph opens downward and if a>0, then graph opens upward.

It is given that the quadratic function opens downward and has its vertex at (0, 1). It means a must be negative.

Putting h=0 and k=1 in (i), we get

[tex]y=a(x-0)^2+1[/tex]

[tex]y=ax^2+1[/tex]

For [tex]a=-1[/tex],

[tex]y=(-1)x^2+1[/tex]

[tex]y=x^2+1[/tex]

So, option A is correct.

In other options the leading coefficient is positive it means their graphs open upward. So, options B, C and D are incorrect.

Therefore, the correct option is A.

On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places

Answers

Answer:

The probability that two of them

die is 0.257

Step-by-step explanation:

From the question, we have that the mortality rate is 0.1

So the probability that they will survive is 1-0.1 = 0.9

Now, we want to check that two will die

We are going you use the Bernoulli approximation of the Binomial theorem as follows

= nCr * p^n * q^(n-r)

where n = 16

r = 2

P = 0.1

q = 0.9

Substituting these values;

14 C 2 * 0.1^2 * 0.9^12

= 0.257

1) Hank is looking to sell his motorcycle. He compiles these prices from the newspaper for bikes just like his
$2,000; $ 16,900; $15,100; $14,500; and $17,000. Is it more reasonable for Hank to use the mean or the
median to get a reasonable estimated price for his bike?

Answers

Answer:

The median

Step-by-step explanation:

If you look at the sample section of the 5 different prices, you can see that $2,000 is very far away from the rest of the prices, which range from $14,000 to $17,000. This $2,000 is an outlier, and is likely not accurate in predicting reasonable prices for Hank's bike, so it should not be a factor in his decision or contribute to the mean value.
