Answer:

£289.20

Step-by-step explanation:

13:2 = x:16 or 13/2 = x/16

cross multiply: 208 = 2x

simplify: x = 104

16 blue tiles x £2.80 each = £44.80

104 white tiles x £2.35 each = £244.40

44.80 + 244.40 = £289.20

100 POINTS!!!!!!!!
yawa3891 [41]

Form the confidence level (99%), we calculate the "alpha" value

alpha=1-(99/100)=0.01

Now, calculate the critical probability (p-start)

p*=1-(alpha/2)=1-(0.01/2)=0.995

z-score could be calculated from p*,,,

z-score=2.57583

Now, calculate the Margin of Error:

standard deviation = s

number of adults = n

ME=(z*s)/(sqrt n)=(2.57583*12)/(sqrt 250) = 1.955

The confidence interval = mean +or- ME

                                     = 70+1.955  or  70-1.955

So that we can conclude that the 99% confidence interval for the mean beats per minute is 68.045 and 71.955

I hope you got the idea!

The subject of the formula is y.<br> y = 4x + 3<br> Rearrange the formula to make x the subject
zysi [14]

Answer:

<h2>x = \frac{y - 3}{4}</h2>

Step-by-step explanation:

y = 4x + 3

To make x the subject send 3 to the other side of the equation

That's

4x = y - 3

<u>Divide both sides by 4 to make x stand alone</u>

\frac{4x}{4}  =  \frac{y - 3}{4}

We have the final answer as

x = \frac{y - 3}{4}

Hope this helps you
