A company manufacturing a roadside lighting system wants to estimate the average illuminance (brightness) at sunset. The illuminance at sunset for the past 10 days was as follows: 406, 385, 389, 383, 352, 379, 388, 343, 368, 387 lux. Construct a 95% confidence intervals for the average illuminance at sunset. Assume that the illuminance at sunset is approximately normally distributed.

Answers

Answer:

(364.595 ; 391.405)

Step-by-step explanation:

Given the sample data:

406, 385, 389, 383, 352, 379, 388, 343, 368, 387

Using calculator :

Sample mean, xbar = 378

Standard deviation, s = 18.74

Confidence interval :

Xbar ± Margin of error

Margin of Error = Tcritical * s/√n

TCritical at df = 24 ; 0.05 = 2.262

Margin of Error = 2.262 * 18.74/√10 = 13.405

Lower boundary = (378 - 13.405) = 364.595

Upper boundary = (378 + 13.405) = 391.405

Answer:

50

Step-by-step explanation:

Given:

qrst ~ nkpm

The ratio of corresponding sides (consider the order of letters in the name of figures):

rs/ kp = qt / nmrs / 35 = 60 / 42rs = 35*60/42rs = 50

Answer:

Solution given:

qrst~nkpm

since the side of similar quadrilateral are proportional so

qt/mn=rs/kp

60/42=?/35

Please help!!! ABCD is a square with diagonals intersecting at E. What is the length of BE

Answers

Answer:

[tex]BE = 4\sqrt2[/tex]

Step-by-step explanation:

Given

The attached square

Required

Find BE

First, we calculate BD (the diagonal) using Pythagoras theorem.

[tex]BD^2 = BA^2 + AD^2[/tex]

Since the shape is a square, then

[tex]BA = AD = 8[/tex]

So:

[tex]BD^2 = 8^2 + 8^2[/tex]

[tex]BD^2 = 2(8^2)[/tex]

Take square roots

[tex]BD = \sqrt{2(8^2)[/tex]

[tex]BD = \sqrt{2} * 8[/tex]

[tex]BD = 8\sqrt{2}[/tex]

BE is half BD.

So:

[tex]BE = \frac{1}{2} * BD[/tex]

[tex]BE = \frac{1}{2} * 8\sqrt2[/tex]

[tex]BE = 4\sqrt2[/tex]

Answer:

B) x = (-5 + √10)/3 and (-5 - √10)/3 is the answer.

Step-by-step explanation:

3x² + 10x + 5 = 0

a = 3

b = 10

c = 5

Finding the Discriminant (D),

D = b² - 4ac

D = 10² - 4 × 3 × 5

D = 100 - 60

D = 40

√D = 2√10

Using quadratic formula,

x = (-b ± √D)/2a

x = (-b + √D)/2a

x = (-10 + 2√10)/2 × 3

Taking out the common factor 2,

x = (-5 + √10)/3

Similarly,

x = (-b - √D)/2a

x = (-10 - 2√10)/2 × 3

x = (-5 - √10)/3

Answers

Answer:

C. 4x + x < 150

find the diagonal that goes through the 3D shape.

Answers

Answer:

Diagonal = 13 yd

Step-by-step explanation:

The diagonal of the 3D shape can be solved using the extension of the pythagorean theorem, which is given as: d² = a² + b² + c²

Where,

a = 12 yd

b = 3 yd

c = 4 yd

d = diagonal

Plug in the values

d² = 12² + 3² + 4²

d² = 169

d = √169

d = 13 yd

The researchers chilled the beverages to 6°C. Participants drank the beverages at the same time each day for three days. During the 3 days of the experiment, the researchers feed each participant the same diet. On the third day participants spent 24 hours in a calorimeter chamber to measure their energy metabolism. The medical journal Obesity published the results in 2007. What is the purpose of double-blinding?

a. To control unintentional researcher bias in the execution of the experiment
b. To control for the participants' prior beliefs about energy drinks
c. To control both unintentional research bias and participant prior beliefs

Answers

Answer:

C. To control both unintentional research bias and participant prior beliefs

Step-by-step explanation:

Double blinding is a type of study where neither the participants nor the researchers know the treatment or intervention that the participants receive until the whole study/research is completed. This is very important because it means that the results gotten from the study have a very slim chance of being biased.

Thus,the correct answer is option C as it includes both the researcher and the participants

Solve the exponential equation for x
3^7x+4=(1/27)^x-3

Answers

Answer:

The solution is [tex]x = \frac{1}{2}[/tex]

Step-by-step explanation:

To solve this exponential equation, we must write both sides as powers of 3.

The equation given is:

[tex]3^{7x + 4} = (\frac{1}{27})^{x-3}[/tex]

Since [tex]3^3 = 27[/tex], we have that [tex]3^{-3} = \frac{1}{3^3} = \frac{1}{27}[/tex], so[tex]\frac{1}{27} = 3^{-3}[/tex]

Then

[tex]3^{7x + 4} = (\frac{1}{27})^{x-3}[/tex]

[tex]3^{7x + 4} = (3^{-3})^{x-3}[/tex]

[tex]3^{7x + 4} = 3^{-3(x-3)}[/tex]

[tex]3^{7x + 4} = 3^{-3x + 9}[/tex]

Since both sides are now powers of 3, we can equal them:

[tex]7x + 4 = -3x + 9[/tex]

[tex]10x = 5[/tex]

[tex]x = \frac{5}{10}[/tex]

[tex]x = \frac{1}{2}[/tex]

The solution is [tex]x = \frac{1}{2}[/tex]

The deer population at the local reserve grows exponentially. The current population is 125 deer and the relative growth rate is 16% per year. Find the number of years required for the deer population to be 400.

Answers

Answer:

About 7.84 years before the deer population is 400

Step-by-step explanation:

So first we write our equation

125(1.16)^x = 400

Then we divide all sides by 125

1.16^x=3.2

x log 1.16 = log 3.2

12 1/3 +6 2/5 reduce these into lowest terms

Answers

Answer:

18 11/15

Step-by-step explanation:

This is the answer because:

1) First, find the common denominator: 12 1/3 = 12 5/15 and 6 2/5 = 6 6/15

2) Then add the fractions: 12 5/15 + 6 6/15 = 18 11/15

3) 18 11/15 is reduced to the lowest terms because 11 is a prime number.

Therefore, 18 11/15 is the answer.

Beth wants to buy Christmas lights to decorate her new home. At various stores, Beth found lights priced from $6.99 a strand to $25.99 a strand. Beth bought almost $200 worth of the cheapest lights so that she could have as many lights on her house as possible. For Beth, Christmas lights are a(n) _____.

Answers

Answer:

Christmas lights are price based shopping products

Step-by-step explanation:

From the question we understand that, Beth bought as many cheapest lights as possible. This means that she places value over quantity than quality.

The above is an illustration of price based shopping products where customers (in this case, Beth) see all products (in this case, Christmas lights) as similar products, irrespective of their different qualities (after all, they all light Christmas trees).

Because of this, the customer will opt for least expensive items, leaving the more expensive items.

If cos theta =12/13.find 1+cot theta

Answers

Answer:

17/5

Step-by-step explanation:

If cosθ = 12/13, find (1+cotθ)

As shown in the diagram attached,

Cotθ = 1/tanθ = adjacent/opposite

From the diagram attached,

cotθ = 12/a................... Equation 1

But we can find the value of a by using  pythagoras theorem

13² = 12²+a²

169 = 144+a²

a² = 169-144

a² = 25

a = √25

a = 5.

Substitute the value of a into equation 1

Therefore,

cotθ = 12/5

(1+cotθ) =(12/5)+1 = (5+12)/5

(1+cotθ) = 17/5

Dave's Candy Store is having a 15% off sale on gourmet candy. Jamal paid $37.40 for a gourmet candy basket that was on sale. What was the original price of the candy basket?

Answers

Answer: $43.01

Why: 37.40 x 0.15
= 5.61
(So the discount was $5.61)

Add it back into the sale...
$43.01

The original price of the gourmet candy is $44, as per linear equation.

What is a linear equation?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, 'x' is a variable, 'A' is a coefficient and 'B' is constant."

Given, the percent of discount at Dave's candy store is 15% = 0.15.

Sale price of a gourmet candy is $37.40.

Let, the original price of the gourmet candy is x.

Therefore, [x - (x × 0.15)] = 37.40

⇒ (x - 0.15x) = 37.40

⇒ 0.85x = 37.40

⇒ x = (37.40/0.85)

⇒ x = 44

Therefore, the original price of the gourmet candy is $44.
