Answer:
8
Step-by-step explanation:
Sum the parts of the ratio 4 + 2 = 6 parts
Divide 24 by 6 to find the value of one part of the ratio
24 ÷ 6 = 4 ← value of 1 part, thus
number of boys = 4 × 4 = 16
number of girls = 2 × 4 = 8
Hence there are 8 more boys than girls
P5
From Z tables and at P5 = 5% = 0.05, Z = -1.645
Therefore,
True value = mean +Z*SD = 24.1+(-1.645*2.1) = 20.6455 Chips per cookie
P95
From Z table and at P95=95%=0.95, Z= 1.645
Therefore,
True value = 24.1 +(1.645*2.1) = 27.5545 Chips per cookie
These values shows the percentages of amount of chips in the cookies. Thus, the more the percentage considered, the more the amount of chips in the cookies. This can be used to control the number of chips in cookies during production.
21/2%=
21/0.02=
1,050
21 is 2% of 1,050
Check:
1,050*2%=
1,050*0.02=
21
