9) c. 6.22 ft < σ < 12.59 ft

10) d. 0.19 oz < σ < 0.72 oz

Step-by-step explanation:

The Confidence Interval, CI are given as follows

For the population proportion

[tex]CI=\hat{p}\pm z\times \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]

1)  [tex]\hat p[/tex] = 55/110 = 0.5

z at 88% = ±1.56

a. CI = 0.426 < p < 0.574

2)  [tex]\hat p[/tex] = 31/669 = 0.5

z at 98% = ±2.326

c. CI = 2.74% < p < 6.524%

3) Here we have unknown population standard deviation, so we find the t interval

[tex]\bar x[/tex] = 21

n = 130

s = 3.0

Confidence level = 98%

[tex]CI=\bar{x}\pm t_{\alpha/2} \frac{s}{\sqrt{n}}[/tex]

[tex]t_{\alpha /2}[/tex] = ±2.356

CI = 20.380 < μ < 21.62

Rounding up gives;

a. CI = 20 < μ < 22

4) Similarly here we have;

[tex]t_{\alpha /2}[/tex] = ±1.699 and

c. CI = 81.11 < μ < 85.09

5) Here

[tex]\bar x[/tex] = 83

s = 13.5

n = 30

Confidence level = 99%

[tex]t_{\alpha /2}[/tex] = ±2.76 and

b. CI = 76.21 < μ < 89.79

6) In the question, we have

[tex]\bar x[/tex] = $664.14

s = $297.29

n = 14

Confidence level = 98%

[tex]t_{\alpha /2}[/tex] = ±2.65 and

CI = $453.56 < μ < $874.72

d. $453.59 < μ < $874.69

7) The confidence interval for a population standard deviation is given by the following relation;

[tex]\sqrt{\frac{\left (n-1 \right )s^{2}}{\chi _{1-\alpha /2}^{}}}< \sigma < \sqrt{\frac{\left (n-1 \right )s^{2}}{\chi _{\alpha /2}^{}}}[/tex]

Here

n = 9

x = $3959

s = $886

Therefore we have

d. CI = $559 < σ < $1953.3

8) Here we have;

n = 41

x = $108

s = $5

Therefore;

c. CI = $3.96 < σ < $6.72

9) Here we have;

n = 29

x = 65 ft

s = 8.5 ft

Therefore we have

CI = 6.3 ft < σ < 12.73 ft

c. 6.22 ft < σ < 12.59 ft

Answer:

y = (5/2)x - 6

Step-by-step explanation:

We need to use slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

Slope is the change in y divided by the change in x. Given the two points, we can find the difference in the y-coordinates and divide that by the difference in the x-coordinates:

m = (-11 - (-1)) / (-2 - 2) = -10 / (-4) = 5/2

Now, we have:

y = (5/2)x + b

Substitute one of the given points for x and y to solve for b:

-1 = (5/2) * 2 + b

-1 = 5 + b

b = -1 - 5 = -6

The answer is y = (5/2)x - 6.

Answer:

y = (5/2)x - 6

Step-by-step explanation:

Slope: (-1 - -11)/(2 - -2)

10/4

5/2

y = (5/2)x + c

-1 = (5/2)(2) + c

-1 = 5 + c

c = -6

y = (5/2)x - 6

Final answer:

The probability of at least two coins landing on heads can be found by calculating the probabilities for each possible number of heads (2 to 10), and adding them together, or by subtracting the probabilities of 0 or 1 head from 1. Each toss has a 50% chance, and binomial probabilities can be used for detailed calculations.

Explanation:

The question is about calculating the probability of at least two coins landing on heads when tossed multiple times. To solve this type of probability problem, one must consider all possible outcomes and then identify the number of favorable outcomes. Assuming each coin tossed is fair, the chance of landing on heads for any single toss is 50%.

Let's consider tossing a coin ten times. Theoretically, one could get an outcome with any number of heads ranging from 0 to 10. To specifically address the probability of getting at least two heads, you would add up the probabilities of getting 2 heads, 3 heads, ..., up to 10 heads. For example, the probability of getting exactly 2 heads in 4 tosses can be calculated using the binomial probability formula, which in this case would be P(X = 2) = (4 choose 2) * (0.5)^2 * (0.5)^(4-2), and you would perform similar calculations for each number of heads from 2 to 10.

The probabilities for getting 0 or 1 heads can be subtracted from 1 to find the probability of getting at least 2 heads. This approach is often easier than adding up all the individual probabilities for 2 to 10 heads. For instance, the probability of getting at least one (one or two) tail in two flips is P(F) = 3/4, where F is the event of getting at least one tail which includes the outcomes HT, TH, and TT.

Final answer:

Destiny needs to prepare at least 3 pans of her gelatin dessert to provide enough servings for 9 people, with each pan holding 8 servings.

Explanation:

Calculating the Minimum Number of Pans Needed

To find out the minimum number of pans Destiny needs to feed 9 people, we need to determine the total number of servings required and then see how many 8-serving pans will cover that need. Destiny plans 16 servings for every 6 people. So for 9 people, we calculate how many servings we would need using a simple proportion:

(16 servings / 6 people) = (x servings / 9 people)
Cross-multiply to solve for x: (16 servings × 9 people) = (x servings × 6 people)
144 servings = 6x servings
Divide both sides by 6: x = 24 servings

Destiny needs 24 servings for 9 people. Each pan holds 8 servings, so the number of pans needed is:

24 servings ÷ 8 servings per pan = 3 pans

Therefore, to make enough gelatin desserts to feed 9 people, Destiny needs at least 3 pans.

Step-by-step explanation:

Answer:

Well, you didnt include answers, but... here's the explanation.

Step-by-step explanation:

Ok so, the sale is 15% off.  As an example, lets use $10 as the original price.  15% off of $10 = 1.5, so we subtract 10 - 1.5 = 8.5.  Now, if the sale tax is 8%, we need to add 8% of 10, which is 0.8 - Now we get our final equation to calculate p, which is 8.5 + 0.8 = P.  8.5 + 0.8 = 9.3, and so the final price after discount AND sales tax are included is $9.3 - Hope this helped.  Mark me as brainliest please :)

Answer:

The answer is C : a cylinder with a base radius of 9 inches

Step-by-step explanation:

The area is 270² inches,  and to find the area of a rectangle is width × length . So the equation would be 270 = W × L, which would convert to 270 = W × 15 and 15 times 18 equals 270. But that is not thew answer because you would need top find the radius of the cylinder which is half of the width of the rectangle which means the radius is 9. So the answer is a cylinder with a base radius of 9 inches.

The resulting three dimensional shape is a cylinder with base radius 9 inches. Option c is correct.

A rectangle ABDE is given with area 270 inches and side AB =15 inches.
This rectangle is rotated about a line passes C and F where C and F is mid points of BD and EA respectively. The shape formed to be determine.

3D or three dimensions is define as when an object is an arbitrary space that its measure obtains on x, y and z axes.

Here,
Area of rectangle ABDE = 270
AB x BD = 270
15 x BD =270
BD = 270/15
BD = 18
Now C is mid point of BD so BC = 18/2
BC = 9
When the given rectangle rotate about CF the new 3d shape arise will  be a cylinder with radius 9 inches.

Thus, the resulting three dimensional shape is a cylinder with base radius 9 inches.

Answer:

x= 6

Step-by-step explanation:

We can use the Pythagorean theorem to find x

x^2 + 2.5^2 = 6.5 ^2

x^2+ 6.25 =42.25

Subtract 6.25 from each side

x^2+ 6.25-6.25 =42.25-6.25

x^2 =36

Take the square root of each side

x = sqrt(36)

x= 6

Answer:

x=6

Step-by-step explanation:

This is a right triangle, because of the little square in the corner. Therefore, we can use the Pythagorean Theorem.

a^2+b^2=c^2

Where a and b are the legs and c is the hypotenuse.

In this triangle, we know that 2.5 and x are the legs, because they form the right angle. We know that 6.5 is the hypotenuse, because it is opposite the right angle.

Therefore, 2.5 and x are a and b, and 6.5 is c.

2.5^2+x^2=6.5^2

Evaluate the exponents

6.25+x^2=42.25

Since we are trying to find x, we have to get x by itself. First, subtract 6.25 from both sides

6.25-6.25+x^2=42.25-6.25

x^2=36

Next, take the square root of both sides, because x is being squared.

Answer:

1,500 bacteria.

Step-by-step explanation:

I don't know what P=Aekt means but I understand the rest:

Hour 0: 1,000 bacteria

Hour 6: 1,300 bacteria

We can conclude from this evidence that it takes 6 hours to grow 300 new bacteria.

Let's use a ratio

new bacteria : hours

      300          :     6

        50          :      1

       500         :     10

So we get 500 new bacteria after 10 hours. Using our original population of 1,000 and our new added members, we get 1,500 bacteria at Hour 10.

Answer:

y+2=3/4(x+5)

Step-by-step explanation:

The first step is to find the slope of the line. Between the two points, the line rises from a y value of -2 to a y value of 4, or a total rise of 6 units. It also goes to the right from an x value of -5 to an x value of 3, which is a total of 8 units. 6 units of rise over 8 units of run is a total slope of 6/8=3/4. Now, you can use the point slope form for either one of the points (I'll use the leftmost one).

y+2=3/4(x+5)

Hope this helps!

One answer in point slope form: y + 2 = (3/4)(x + 5)

Answer in slope intercept form: y = (3/4)x + 7/4

Answer in standard form: 3x-4y = -7

===============================================

Explanation:

First we need the slope of the line

Find the slope of the line through (x1,y1) = (-5,-2) and (x2,y2) = (3,4)

m = (y2 - y1)/(x2 - x1)

m = (4 - (-2))/(3 - (-5))

m = (4 + 2)/(3 + 5)

m = 6/8

m = 3/4

-------

Plug m = 3/4 and (x1,y1) = (-5,-2) into the point slope formula. Solve for y.

y - y1 = m(x - x1)

y - (-2) = (3/4)(x - (-5))

y + 2 = (3/4)(x + 5)

y + 2 = (3/4)x + (3/4)*5 ... distribute

y + 2 = (3/4)*x + 15/4

y + 2 - 2 = (3/4)*x + 15/4 - 2 ... subtract 2 from both sides

y = (3/4)x + 15/4 - 8/4

y = (3/4)x + (15-8)/4

y = (3/4)x + 7/4

This equation is in slope intercept form y = mx+b

m = 3/4 is the slope, b = 7/4 is the y intercept

-------

Multiply both sides by 4 to help convert to standard form

y = (3/4)x + 7/4

4y = 3x+7

-7 = 3x-4y

3x-4y = -7

This is in the form Ax+By = C

A = 3, B = -4, C = -7

Answer:

Step-by-step explanation:

Because two points determine a line, you can draw altitude​ BD perpendicular to AC with height h. By the definition of a sine ratio, sin(C) = h/a, which can be rearranged into​ a·sin(C) = h​. The area of △ABC is A=1/2bh. The substitution property of equality can be used to write A=1/2b(a sinC), which becomes A=1/2ab(sinC) by the commutative property of multiplication.

___

The mnemonic SOH CAH TOA reminds you that the sine ratio is ...

  Sin = Opposite/Hypotenuse

Here, the side of the right triangle opposite angle C is designated "h", the height of ∆ABC. The hypotenuse of that right triangle is side "a". So ...

  sin(C) = h/a

__

The substitution property of equality lets you replace any expression with its equal. Here, we have h=a·sin(C), so we can use a·sin(C) in place of h in the formula for triangle area:

  1/2bh = 1/2ba·sin(C)

__

The commutative property of multiplication lets you rearrange the order of the factors in a product, so ...

  ba = ab

and

  A = 1/2ba·sin(C) = 1/2ab·sin(C)
