The results of a survey indicate that the true proportion of households who recycle paper products
is likely in the interval (0.61,0.7).
What is the point estimate of the proportion of households who recycle paper?
Enter your answer, as a decimal, in the box.​

Answers

Answer 1

Answer:

[tex] 0.61 \leq p \leq 0.70[/tex]

And for this case we can estimate the proportion of households who recycle paper is given by:

[tex] \hat p = \frac{Upper +Lower}{2}[/tex]

And replacing we got:

[tex] \hat p =\frac{0.7+0.61}{2}= 0.655[/tex]

And for this case the answer is 0.655 for the proportion of households who recycle paper

Step-by-step explanation:

For this case we know that the confidence interval for the proportion of interest is given by:

[tex]\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex]

And for this case the confidence interval is given:

[tex] 0.61 \leq p \leq 0.70[/tex]

And for this case we can estimate the proportion of households who recycle paper is given by:

[tex] \hat p = \frac{Upper +Lower}{2}[/tex]

And replacing we got:

[tex] \hat p =\frac{0.7+0.61}{2}= 0.655[/tex]

And for this case the answer is 0.655 for the proportion of households who recycle paper

Test each of the following to see if it is divisible by 2,3,4,5,6,8,9,10, or 25 and say why.

1)24

Answers:

Divisible by 2: yes, because it is an even number. The even numbers are those which end in 0, 2, 4, 6, or 8. Result: 24/2 = 12

Divisible by 3: yes, because the sum of its digits is a multiple of 3: 2 + 4 = 6 is a multiple of 3. Result: 24/3 = 8

Divisible by 4: yes, result: 24/4 = 6

Divisible by 5: no, because a number is divisible by 5 if it ends in 0 or 5.

Divisible by 6: yes, because it is divisible by 2 and by 3, then it is divisible by 6. Result: 24/6 = 4.

Divisible by 8: yes, result: 24/8 = 3

Divisible by 9: no, because the sum of its digits is not a multiple of 9.

Divisible by 10: no, because a number is divisible by 10 if it ends in 0.

Divisible by 25: no, because 25 is a number greater than 24.

Answer:

384 cubic meters

Step-by-step explanation:

Think of it as two rectangles on top of each other and then add the two volumes.

Volume is l*w*h

So for the bottom rectangle: (8) (12) (2) = 192 cubic meters

And for the top rectangle: (4)(6)(8) = 192 cubic meters

It is important to remember that for the top box you have to subtract the height of the bottom box which is why I used 4 for the height instead of 6.

Then you add them together.

192+192 = 384 cubic meters

Jocelyn has 6 birds. Their mean age is 10. The mode of their age is 8 . What might there ages be ??.

Subject - Math ( Mean, Median, and Mode ) PLZ write the answer correctly !! The best answer will be marked as Braintlies !!

Answers

Answer:

total ages = 60

Generally, if the mode is 8 would mean there are more than one age of 8

suppose there are two with age 8,

leaving 44 for the other 4

(11 for the average of the remaining 4)

could have 9 and 13, and 8 and 14

so we could have:

8,8,8,9,13,14

or we could have:

8,8,9,10,12,13

check:of the 1st answer

mean = (8+8+8+9+13+14)/6 = 10

the mode is 8

Step-by-step explanation:

The mean is all the 6 birds ages added together then divided by how many of the birds there is. The mode is the most occurring number.
Because there is 6 birds having all the ages add up to 60 then dividing it by the 6 will give you the mean 10.
When making those numbers you need to make sure that you have multiple 8’s because that is the mode which means the most occurring number.
The answer could be :
8+8+8+13+12+11
8+8+8+8+18+10

Quadrilateral ABCD is the result of a reflection of quadrilateral LMNO over the line. Which line segment in the image corresponds to NO in the pre-image? I want to say CD but not 100% sure. Only correct answers please. Very important. Working on it now​

Answers

Answer:

CD

Step-by-step explanation:

Reflection is a rigid transformation which always create a congruent image of the original image or pre-image.

If quadrilateral ABCD is the result of a reflection of quadrilateral LMNO over the line.

Then both the quadrilaterals are congruent.

To find the line segment in the image corresponds to NO in the pre-image, just check the order of the letters in the name of quadrilaterals.

Also, In reflection image and its pre-image are equidistant from the line of reflection

hence, CD is the line segment in the image corresponds to NO in the pre-image.

A restaurant owner is replacing the restaurant’s bathroom floor with square tiles.

The tiles will be laid side-by-side to cover the entire bathroom with no gaps, and none of the tiles can be cut.

The floor is a rectangle that measures 24 feet by 18 feet.

Then the area of the bathroom will be

Area = 24 x 18

Area = 432 square feet

Let n be the number of tiles and a be the side length of the square tile.

na² = 432

If a = 1, Then the number of tiles will be

n = 432

If a = 2, Then the number of tiles will be

n x 2² = 432

n x 4 = 432

n = 108

The number of tiles will be 108. And the largest possible tile size she could use will be 2 feet.

Use ​ ≈ 3.14 and round your answer to the nearest hundredth

Height is 10ft

Answers

Answer:

The radius of the cone is 6 feets.

Step-by-step explanation:

We have,

Volume of the cone is 376.8 cubic feet

Height of the cone is 10 ft

It is required to find the radius of this cone. The formula of the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]

r is radius of cone

[tex]r=\sqrt{\dfrac{3V}{\pi h}} \\\\r=\sqrt{\dfrac{3\times 376.8}{3.14\times 10}} \\\\r=6\ ft[/tex]

So, the radius of the cone is 6 feets.

A data set is normally distributed with a mean of 115 and a standard deviation of 23. What is the probability that a value in the data set is greater than or equal to 162?
The probability is about __

Answers

Answer:

The probability that a value in the data set is greater than or equal to 162

P(X≥162) = 0.0207

Step-by-step explanation:

Step(i):-

Given mean of the Population = 115

Given standard deviation of the Population = 23

Let 'x' be the random variable of normal distribution

Let x = 162

[tex]Z = \frac{x-mean}{S.D} = \frac{162-115}{23}[/tex]

z = 2.043

Step(ii):-

The probability that a value in the data set is greater than or equal to 162

P(X>x) = P(Z>z) = P(Z> 2.043)

P(X≥162) = P(Z≥2.043) = 1-P(Z≤ 2.043)

                                      =  1- ( 0.5 +A(2.043)

                                      =   1-0.5 -A(2.043)

                                      =    0.5 - 0.4793

                                      =  0.0207

Final answer:-

The probability that a value in the data set is greater than or equal to 162

P(X≥162) = 0.0207

Answers

Answer:

Number of year to get $10,000 as interest = 7.5 year (Approx)

Step-by-step explanation:

Given:

Initial investment = $20,000

Interest on investment = $10,000

Rate of interest = 5.6% = 0.056

Find:

Number of year to get $10,000 as interest:

Computation:

[tex]Interest\ on\ investment = Initial\ investment[(1+r)^n-1]\\\\10,000 = 20,000[(1+0.056)-1]\\\\0.5=(1.056)^n-1\\\\1.5 =(1.056)^n\\\\n=7.44[/tex]

Number of year to get $10,000 as interest = 7.44

Number of year to get $10,000 as interest = 7.5 year (Approx)

Step-by-step explanation:

Let X the random variable of interest "number of craked eggs", on this case we now that:

The probability mass function for the Binomial distribution is given as:

[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]

Where (nCx) means combinatory and it's given by this formula:

[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]

And we want to find this probability:

[tex]P(x \geq 1)=1-P(X<1)= 1- P(X=0)[/tex]

And we can find the probability:

[tex]P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801[/tex]

And replacing we got:
