Think about a population proportion that you may be interested in and propose a confidence interval problem for this parameter.

o-na [289]

Answer: The confidence interval would be (0.2928,0.3672).

Step-by-step explanation:

Since we have given that

Total number of vehicles = 432

Number of SUVs sold = 142

So, it becomes,

$\hat{p}=\dfrac{x}{n}=\dfrac{142}{432}=0.33$

At 90% confidence interval,

z = 1.645

So, the confidence interval would be

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.33\pm 1.645\sqrt{\dfrac{0.33\times 0.67}{432}}\\\\=0.33\pm 0.0372\\\\=(0.33-0.0372,0.33+0.0372)\\\\=(0.2928,0.3672)$

Hence, the confidence interval would be (0.2928,0.3672).

Jasmine cooked 1 5/6 kg of rice. Alice cooked 5/8 kg more than Jasmine. a. How many kg of rice did Alice cook? b. How many kg of

larisa86 [58]

Answer:Amount of rice cooked by Alice =2 11/24kg

Together Alice and Jasmine cooked 4 7/24kg of rice

Step-by-step explanation:

Amount of rice cooked by Jasmine =1 5/6 kg

Amount of rice cooked by Alice = 5/8 kg more than Jasmine

=1 5/6 kg+ 5/8 kg

=1 (20 +15) /24

=1 35/24

=1 +1 11/24

= 2 11/24 kg

Together Alice and Jasmine cooked 1 5/6 kg + 2 11/24kg =

=3 20 +11/24

=3 31/24=3 +1 7/24

=4 7/24kg

The sum of the ages of Raj and Ben is 37 years. 5 years ago, Raj's age was twice of Benn. Find their present ages. (STEP BY STEP

qwelly [4]

Answer:

Raj is 27 yrs and Be is 14 yrs

Step-by-step explanation:

let the age of Raj be x and Ben be y

case_1

x + y =37

x = 37 - y

case_2

x - 5 = 2(y -5)

x-5 = 2y -10

37 - y -5 = 2y - 10

32 + 10 = 2y + y

42 = 3y

y = 14 yrs

now,

x = 37 - 14

x = 27

Write a division expression with quotient that is greater than 8 divided 0.001

Jet001 [13]

Answer:

Expression is '98 divided by 0.005' i.e. $\frac{98}{0.005}$ .

Step-by-step explanation:

We have that,

The quotient of 8 divided by 0.001 is given by,

$\frac{8}{0.001}$ = $\frac{8\times 1000}{1}$ = 8000.

It is required to find a division expression having quotient greater than 8000.

Let us consider,

'98 divided by 0.005'

i.e. $\frac{98}{0.005}$

i.e. $\frac{98\times 1000}{5}$

i.e. 98 × 200

i.e. 19,600

Thus, the get the quotient of the new expression 19,600 > 8000.

Hence, the required expression is '98 divided by 0.005' i.e. $\frac{98}{0.005}$ .
