Q1 of company A = 2.5
Q3 of company A = 8
Interquatile range = (Q3 - Q1)/2 = (8 - 2.5)/2 = 5.5/2 = 2.75

Q1 of company B = 2
Q3 of company B = 5.5
Interquatile range = (5.5 - 2)/2 = 3.5/2 = 1.75

A polynomial p has zeros when I = 0.2 = -
Rainbow [258]

Answer:

p(x) = (5x - 1) (x + 3)

Step-by-step explanation:

I apologize if I couldn't answer correctly, the question was a bit hard to understand because of the formatting.

Also I didn't see my answer in the list of answer choices but here it is:

if the polynomial has zeros at 0.2 and -3 the equation would have to be:

p(x)=(x-0.2)(x+3)

This is because plugging either of those numbers into the polynomial would cause it to equal 0.

(x-0.2) can be simplified by multiplying everything in the parenthesis by 5, getting rid of all of the decimals, making the final answer:

p(x) = (5x - 1) (x + 3)

Stephen and Bridget win some money and share it in the ratio 1:3. Stephen gets £11. How
pentagon [3]

Answer:

£44

Step-by-step explanation:

We have been given the ratio 1 : 3 , where 1 is stephens value and 3 is bridgets value.

We have told that stephen gets £11.

The relationship between stephens 'value' of 1 and the amount of money that he actually gets (11) is x11.

Therefore we must also x11 to Bridgets value.

11 x 3 = £33

Now, we add the two answers to find how much they won in total.

£33 + £11 = £44

hope this helps :)
