A bank sampled its customers to determine the proportion of customers who use their debit card at least once each month. A sampl

Zinaida [17]

Answer:

(0.084,0.396)

Step-by-step explanation:

The 99% confidence interval for the proportion of customers who use debit card monthly can be constructed as

$p-z_{\frac{\alpha }{2}} \sqrt{\frac{pq}{n} }$

$p=\frac{x}{n}$

$p=\frac{12}{50}$

$p=0.24$

$q=1-p=1-0.24=0.76$

$\frac{\alpha }{2} =\frac{\0.01 }{2}=0.005$

$p-z_{\frac{\alpha }{2}} \sqrt{\frac{pq}{n} }$

$0.24-z_{0.005} \sqrt{\frac{0.24*0.76}{50} }$

$0.24-2.58(0.0604)$

$0.24-0.155832$

By rounding to three decimal places we get,

$0.084$

The 99% confidence interval for the proportion of customers who use debit card monthly is (0.084,0.396).

Students sold 300 tickets for a playoff game in basketball at school. Some tickets are for students and cost $4.00, while the re

Neko [114]

So baically

reresent
s=number of studne tickes bouthgt
a=number of adult tickets bought

300 tickest sold
total=300
a+s=300

value=rate times number of peple

student value=4s
adults value=10a
total value=1950
4s+10a=1950

a. system of equations are
s+a=300
4s+10a=1950

b. solve

s+a=300
4s+10a=1950

a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution

4s+10a=1950
<u>-4s-4a=-1200 + </u>
0s+6a=750

6a=750
divide 6
a=125

subsiute
s+a=300
s+125=300
subtract 125
s=175

a. s+a=300
4s+10a=1950

b. solution above
175 students
125 aduls

Answer:

C) 324 cm^3

Step-by-step explanation:

So you know the volume and 2 side lengths. 360 divided by 12 divided by 5 to find the third side. The third side is 360 / 60 (answer of 12x5), which is 6. Surface area of prism is 324 (c)
