Answer:

D. the standard error of the mean

Step-by-step explanation:

trust me i got it right Plato

The value needed to determine a confidence interval for a sample mean is the standard error of the mean option (D) is correct.

It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.

The formula for finding the confidence interval for population standard deviation as follows:

[tex]\rm s\sqrt{\dfrac{n-1}{\chi^2_{\alpha/2, \ n-1}}} < \sigma < s\sqrt{\dfrac{n-1}{\chi^2_{1-\alpha/2, \ n-1}}}[/tex]

Where s is the standard deviation.

n is the sample size.

[tex]\chi^2_{\alpha/2, \ n-1} and \chi^2_{1-\alpha/2, \ n-1}[/tex] are the constant based on the Chi-Square distribution table:

α is the significance level.

σ is the confidence interval for population standard deviation.

Calculating the confidence interval for population standard deviation:

We know significance level = 1 - confidence level

It is given that:

The value needed to determine a confidence interval for a sample mean is the standard error of the mean.

CI = X + Z(s/√n)

Here CI is the confidence interval

Z is the confidence level

X is the sample mean

Thus, the value needed to determine a confidence interval for a sample mean is the standard error of the mean option (D) is correct.

Answer:

c. 273 cars

Step-by-step explanation:

First you need to find what 16% of 325 is

325x.16=52

because the number sold dropped by 16% you will subtract 52 from 325

325-52=273

you can also calculate the answer by subtracting 100% by 16%

100%-16%=84%

now you can calculate 84% of 325

325x.84=273

Answer:

D: ∛(¼(x + 5))

Step-by-step explanation:

The parent function is;

f(x) = ∛x

A horizontal stretch multiplying by ¼ means that our function is now;

f(x/4) = ∛(x/4)

Now shifting to the left by 5 units denotes;

f(x + 5) = ∛((x + 5)/4)

Or expressed as; ∛(¼(x + 5))

(5x + 15)⁰+ (3x - 3⁰) = 180⁰ ( same side on interior angle theorm)

(8x + 12)⁰= 180⁰

8x = 168⁰

x = 21

Angle 1 +( 3x - 3)⁰ = 180⁰⁰ ( linear pair)

Angle 1 + 63 - 3⁰ = 180⁰

Angle 1 + 60⁰ = 90⁰

Angle 1 = 180⁰- 60⁰

Angle 1 = 120⁰

Answer:

(5x+15)°+(3x-3)°=180°(by co interior angle)

5x+3x+15 - 3=180°

8x+12=180°

8x=180°-12

8x=168°

x=168/8

x=21

by putting value of x

(3x-3)° = 3×21-3 = 60°

60°+angle 1 = 180°[by linear pair]

angle 1=180°-60°

angle 1=120°

Answer:

C. 139 ft

Step-by-step explanation:

Height of the pole = x + 4 ft

First, find x using trigonometric function.

Reference angle = 44°

Opposite side length = x

Adjacent side length = 140 ft

Apply TOA, which is:

Tan 44 = opp/adj

Tan 44 = x/140

Multiply both sides by 140

140 × Tan 44 = x

135.196428 = x

x ≈ 135 ft

✔️Height of the pole = x + 4 ft = 135 + 4 = 139 ft

Complete question :

A business owner wants to know if it will be profitable to open a new coffee shop in a nearby town.In towns where the shop has been successful,the shop name is recognizable to people 53% of the time .He survey random sample of 12 residents of the town.  Find the probability that among these 12 surveyed residents, none of them have ever heard of the coffee shop

Answer:

0.000116

Step-by-step explanation:

Using the binomial probability relation :

Probability of success, p = 0.53

1 - p = 0.47

Number surveyed, n = 12

P(x =x) = nCx  * p^x * (1 - p)^(n - x)

Probability that none has heard of the coffee shop :

P(x = 0) = 12C0 * 0.53^0 * 0.47^12

P(x = 0) = 0.000116

Answer:

B:81

C:99

D:81

Step-by-step explanation:

In a parallelogram, opposite angles are congruent and consecutive angles (angles next to each other) are supplementary, or add to 180. Considering that there is no diagram, we can use our imagination here. So B is next to A, so <A+<B=180. <B must equal 81. I repeated this process for the rest of the angle measures.

[tex]\\ \sf\longmapsto <A=<C=99°[/tex]

sum of corresponding angles is 180°

[tex]\\ \sf\longmapsto <A+<B=180[/tex]

[tex]\\ \sf\longmapsto 99+<B=180[/tex]

[tex]\\ \sf\longmapsto <B=180-99[/tex]

[tex]\\ \sf\longmapsto <B=81[/tex]

[tex]\\ \sf\longmapsto <B=<D=81°[/tex]

Answer:

16.5

Step-by-step explanation:

Given data to us is ,

Arrange it in ascending order .

= 12 , 14 , 15 , 16 , 17 , 20 , 20 , 22

The middle most observation will be median in case n is odd and average of middlemost observations if n is even , that is n = 8 .

=> Middlemost observations = 16 , 17

=> Mean = 16 + 17 /2 = 33/2 = 16.5

Answer:

s = 6 feet

Step-by-step explanation:

Given that,

The volume of the cube, V = 216 feet³

We need to find the side length for the cubical box. We know that the volume of the cube is given by :

[tex]V=s^3[/tex], s is the side length of the box.

So,

[tex]s={V}^{1/3}\\\\s={216}^{1/3}\\\\s=6\ feet[/tex]

So, the side length for the cubical box is equal to 6 feet.

Answer:

I think the answer is A, $5.60

Step-by-step explanation:

9.80 x 9= 88.20

88.20 - 37.80 = 50.40

5.60 x 9 = 50.40

The average amount paid for the books is $12.60

Since Xuan sold 9 used books for $9.80 each, the total amount that's paid for the books will be:

= $9.80 × 9

= $88.20

Since she bought 4 new books and had $37.80 left over, the cost of the books will be

= $88.20 - $37.80

= $50.40

Since she bought 4 books, the average amount paid for the books will be:

= $50.40/4

= $12.60

Therefore, the correct option is D

Step-by-step explanation: To start off, note that 4 1/4 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.

4 = Whole number

1 = Numerator

4 = Denominator

To get 4 1/4 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.

Here are the detailed math steps we use to convert 4 1/4 mixed number to decimal form:

Step 1: Multiply the whole number by the denominator:

4 × 4 = 16

Step 2: Add the product you got in Step 1 to the numerator:

16 + 1 = 17

Step 3: Divide the sum from Step 2 by the denominator:

17 ÷ 4 = 4.25
