Kat is interested in getting chickens so she can have fresh eggs. Before she buys her chickens, she wants to find the mean number of eggs each one will lay. She begins by randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month. She finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs. Which of the following is the 90% confidence interval for the true mean number of eggs chickens from this poultry farm lay in one month?

Find the t-table here.

(21.85, 27.75)
(22.59, 27.01)
(22.96, 26.64)
(23.38, 26.22)

Answers

Answer:

C

Step-by-step explanation:

Took it

The confidence interval of eggs chickens from this poultry farm lay in one month will be (22.96, 26.64). Then the correct option is C.

What is the confidence interval of the sample?

If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.

Let the sample mean given as μ and

The sample standard deviation σ, and

The sample size = n, and

Then the heights would be outside the 90% confidence interval will be

For 90% confidence interval, we have z = 1.645

⇒ μ ± z (σ/√n)

Answer:

x=8

Step-by-step explanation:

13=x+5

8=x

Answer:

x = 8

Step-by-step explanation:

Okay, so the top and bottom of a parallelogram are equal (or else it would be a trapezoid), so we just have to construct our cute lil algebraic expression:

x + 5 = 13

So now we have to do the inverse operations thingy:

13 - 5 = 8

So x = 8

Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.

Answers

Answer:

6:5

Step-by-step explanation:

Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.

The algae is spherical in nature

Volume of the algae =4/3 pi r³

Volume of the algae = 4/3×pi×2.5³

Volume of the algae = 62.5/3 pi

Surface area = 4pi r²

Surface area = 4pi ×2.5²

Surface area = 25pi

Taking their ratio

surface area : volume ratio

= 25pi:62.5/3 pi

= 25 × 3/62.5

= 1.2

Hence the required ratio is 12/10 which is 6:5

A football field measures 300 feet in length. It can also be expressed as approximately

5.7 x 10^n .

If there are 5,280 feet in 1 mile , which is the most reasonable value of n.

Answers

Answer: n=-2

Step-by-step explanation:

Given

The length of the football field is  [tex]300\ ft[/tex]

In the mile, it can be expressed as [tex]5.7\times 10^n\ mile[/tex]

Also, [tex]5280\ ft=1\ mile[/tex] or

[tex]1\ ft=\dfrac{1}{5280}\ miles\\\\1\ ft=1.893\times 10^{-4}\ miles[/tex]

converting [tex]300\ ft[/tex] to miles

[tex]\Rightarrow 300\times 1.893\times 10^{-4}\\\Rightarrow 5.68\times 10^{-2}\approx 5.7\times 10^{-2}[/tex]

Comparing it with the given value [tex]5.7\times 10^n\ mile[/tex]

we get [tex]n=-2[/tex]

Which value of x makes the equation 0.75(x + 20) = 2 + 0.5(x - 2) true?

Answers

Answer:

x = -56

Step-by-step explanation:

0.75(x + 20) = 2 + 0.5(x - 2)

0.75x + 15 = 2 + 0.5x - 1

0.25x = -14

x = -14/0.25

x = -56

Step 1: Simplify both sides of the equation.

0.75 (x + 20) = 2 + 0.5 (x − 2)
(0.75)(x)+(0.75)(20) = 2+(0.5) (x) + (0.5)(−2)
(Distribute)

0.75x + 15 = 2 + 0.5x + −1
0.75x + 15 = (0.5x) + (2 + -1)

(Combine Like Terms)
0.75x + 15 = 0.5x + 1

Step 2: Subtract 0.5x from both sides.
0.75x + 15 − 0.5x = 0.5x + 1 − 0.5x
0.25x + 15 = 1

Step 3: Subtract 15 from both sides.
0.25x + 15 − 15 = 1 − 15
0.25x = −14

Step 4: Divide both sides by 0.25.
0.25x/0.25 = −14/0.25x

x = -56

Find the value of x and y that will make each quadrilateral a parallelogram.​

Answers

Answer:

the opposite Angles sum up to give 180

Step-by-step explanation:

3y +3y = 180

y=30

if y = 30 the x = 55

are you clear?

Answer:

3y+3y=180°{sum of opposite angle of parallelogram are supplementary}

6y=80

y=180/6

y=30°

again,

4y-65+x=180°{ sum of of opposite angle of parallelogram are supplementary }

4×30-65+x=108

x=180-55

x=125

so to make quadrilateral as parellogram

4,12,20 find the 41st term

Answers

Answer:

The 41st term of the given series is 324

Step-by-step explanation:

a= 4

a2= 12

d= a2-a

d= 12-4 = 8

now, we have to find 41 term that is a41

a41 = a+ 40d

a41= 4+ 40× 8

a41= 4+ 320

= 324

therefore the 41st term is 324

Answer:

324

Step-by-step explanation:

The sequence observed appears to be an arithmetic sequence. The formula for an arithmetic sequence is an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, n is the term position, and d is the common difference. Let's write down what we know.

n = 41

a1 = 4

d = 8

So, let's plug our values into the equation and solve.

an = 4 + (41 - 1)8

an = 4 + (40)8

an = 4 + 320

an = 324

If t varies inversely as a and t= 2 when a = -4, what is t when a = 1/3?

1. -2 2/3
2. -24
3. - 1/6
4. -2/3

Answers

Answer:

t = - 24

Step-by-step explanation:

Given t varies inversely as a then the equation relating them is

t = [tex]\frac{k}{a}[/tex] ← k is the constant of variation

To find k use the condition t = 2 when a = - 4

2 = [tex]\frac{k}{-4}[/tex] ( multiply both sides by - 4 )

- 8 = k

t = [tex]\frac{-8}{a}[/tex] ← equation of variation

When a = [tex]\frac{1}{3}[/tex] , then

t = [tex]\frac{-8}{\frac{1}{3} }[/tex] = - 24

The probability that  the pitcher will throw 4 or fewer pitches to a batter is 0.9.

What is Probability ?

The way to find the likeliness of an event is called Probability.

It is given that

Pitcher is throwing ball

The probability that he throws 4 or fewer pitches to a batter is = ?

The no. of favourable outcomes for the given condition is

P(X ≤4 ) = P(X=1) + P(X =2) + P(X=3)+P(X=4)

Total Outcomes = 15+20+40+15+20

Total outcomes = 100

Favourable outcomes = 15+20+40+15

Favourable Outcomes = 90

Probability =  Favourable Outcomes / Total Outcomes \

Probability = 90/100 = 0.9

Therefore the probability that  the pitcher will throw 4 or fewer pitches to a batter is 0.9.

A circle has a circumference whose length is 25(pi). Find the length of an arc whose central angle is 120.

Answers

9514 1404 393

Answer:

  (25/3)π

Step-by-step explanation:

A central angle of 120° is 1/3 of a circle, so the arc length will be 1/3 of the circumference:

  (1/3)(25π) = (25/3)π ≈ 26.18 . . . . units

Answer:

Solution :-

Circumference = 25π

Total angle made by circle = 360

Now,

120 is ⅓ of 360⁰.

⅓ × 25π = 25π/3

Hence,

Length of arc = 25π/3
