ch4aika [34]

Answer:

1) His total commission is $1,234.3

2) The purchase of the car is $24,790.

Step-by-step explanation:

1) 21640*0.02= 432.8+ 250= 682.8

15075*0.02= 301.5+ 250= 551.5

682.8+ 551.5= 1,234.3

2) 745.8- 250= 495.8/ 0.02= 24,790

From an industrial area 70 companies were selected at random and 45 of them were panning for expansion next year. Find 95% confi

Lana71 [14]

Answer:

Confidence limit = [52.8%, 75.2%]

Step-by-step explanation:

$P=\frac{45}{70}= 0.64$

$(1-P)=1-0.64=0.36$

$n= 70$

$P$ ± $z$ $\sqrt{\frac{P(1-P)}{n} }$

where the value $z$ will be taken from the z-table for 95% confidence interval

1-0.95= 0.05/2= 0.025

0.95+0.025= 0.0975

From the z-table the value of $z$ corresponding to 0.0975 is 1.96

$0.64$ ± $1.96$ $\sqrt{\frac{0.64*0.36}{70} }$

$0.64$ ± $1.96$ $(0.057)$

$0.64$ ± $0.112$

$64%$ % ± $11.2$ %

so the confidence interval is

$64+11.2=75.2$ %

$64-11.2=52.8$ %

$[52.8, 75.2]$

Actual price - Old Price= New price

New price/Old Price * 100/1

From the above question.. $18= Old price , $20= New price

So 20-18 = 2(New Price)

2/18 *100 = 0.11 * 100 = 11%

xenn [34]

Answer:

the number of children has red or brown hair is $\frac{2}{3}$ .

Step-by-step explanation:

We have been given that in Marci's family there are total 6 children.

Out of 6 children

Number of children have blonde hair = $\frac{1}{3}$

Number of children have red hair = $\frac{1}{6}$

Number of children have brown hair = $\frac{1}{2}$

Since, we have to find the fraction of children has red or brown hair= $\frac{1}{6}+\frac{1}{2}=\frac{4}{6}=\frac{2}{3}$

Hence, the number of children has red or brown hair is $\frac{2}{3}$
