The expected number of left-handed people in the sample= 45

<h3>Calculation of total number of left-handed</h3>

The number of people selected at random= 450

The percentage of people that are left-handed =10%

Therefore, the number of people that are left-handed,

= 10/100 * 450

= 4500/100

= 45

balu736 [363]
The restaurants sold 50 salads.

-The given is that they sold 35 garden salads which is 70% of their sales.
-Now, to get how many salads 1% is equal to, you divide 35 by 70
-35/70 = 0.5
-So now, multiply 16 by 0.5 and 14 by 0.5
-16(0.5)=8 and 14(0.5)=7
-Add the three together to get 50
-Now, check to see if it works
70% of 50 is 35
16% of 50 is 8
14% of 50 is 7

Hope this helps and is right, have a good day!
