9+12=m or 9+12=21

this is because when we start with m-9=12 we know that m is supposed to be the sum of 9 and 12.

if we check our work we will see this

9+12=21

9+12=21

m-9=12

21-9=12

Kobotan [32]
Missing info:
Turkey Sizes: 
<span>small - 2kg - 3.9kg </span>
<span>medium - 4kg - 5.4kg </span>
<span>large - 5.5kg - 7.2kg </span>
<span>extra large - 7.3kg - 9.2kg </span>

<span>Turkey Prices: </span>
<span>Small / Medium - £5.99 per kg </span>
<span>Large / Extra Large - £4.99 per kg 
</span>
3/4 lb x 14 persons = (3*14)/4 = 42/4 = 10.5 lbs

1 lb = 450 grams

10.5 lbs * 450grams/lb = 4,725 grams

1 kg = 1000 grams

<span>4,725 grams * 1kg/1000 grams = 4725 kg / 1000 = 4.725 kg.

4.725 kg is under the Medium size of the Turkey.

Medium sized turkey costs </span>£<span>5.99 per kg.

4.725 kg * </span>£5.99 per kg = £<span>28.30

A turkey would cost </span> £<span>28.30 for 14 people.</span>

Find the indicated IQ score. The graph to the right depicts IQ scores of​ adults, and those scores are normally distributed with
larisa86 [58]

Based on the mean, standard deviation, and the graph, the indicated IQ score would be 115.

<h3>What is the indicated IQ score?</h3>

First, find the z value:

P(Z<z) = 1 - tail value

= 1 - 0.1587

= 0.8413

According to the z-value, this gives a value of:

z = 1

The indicated IQ score is:

= mean + z value z standard deviation

= 100 + 1 x 15

= 115
