Answer:

The minimum percentage of stores that sell a gallon of milk for between $3.47 and $3.91 is of 75%.

Step-by-step explanation:

Chebyshev Theorem

The Chebyshev Theorem can also be applied to non-normal distribution. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].

In this question:

Mean of $3.69, standard deviation of $0.11.

What is the minimum percentage of stores that sell a gallon of milk for between $3.47 and $3.91?

3.47 = 3.69 - 2*0.11

3.91 = 3.69 + 2*0.11

So the minimum percentage within 2 standard deviations of the mean, which by Chebyshev's Theorem, is of 75%.

Answer:

26. H

Step-by-step explanation:

26. An acute angle just has to be less than 90 degrees. Therefore, H is the correct choice.

Please mark as brainliest

Answer:

Angle H

Step-by-step explanation:

Angle H is correct because it is less than 90 degrees. Any angle more than 90º is obtuse. Any angle that is 90º is classified as a right angle.

For example,

Angle I is an obtuse angle.

Angle F is a right angle.

Answer:

$50

Step-by-step explanation:

If the original price was $10 more than the sale price, so we know that in this case, 20% = $10. Because 20% is equivlalent to [tex]\frac{1}{5}[/tex], multiply $10 by 5 to get the answer of $50.

The available options are

A) 10

B) 11

C) 30

D) 91

E) The number depends on the size of the population.

Answer:

91

Step-by-step explanation:

Given that for the normal approximation, we need that:

np > 5 and np(1-p) > 5

Hence, we have

n = 91

91*0.89 = 80.99

91*0.89*0.11 = 8.9089 > 5

Therefore the answer gotten is satisfactory or satisfies the condition, and which makes 91 the accurate solution.

The other options, when calculated is less than 5

Answer:

The area of the triangle is 40 [tex]yd^2[/tex].

Step-by-step explanation:

The formula for finding the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] and [tex]h[/tex] represents the base length and height respectively. Since the height is 10 yards, and the base length is 8 yards, that means the area will be [tex]\frac{1}{2} * 8 * 10 = \frac{1}{2} * 80 = 40 yd^2[/tex].

Answer:

0.01024

Step-by-step explanation:

Assume marking was done at random : Hence, each of the 5 time slots have equal Chamves of being marked ;

Number of time slots, n = 5

Required to mark, number of preferred timeslot x = 2

P(x) = 2 /5 = 0.4

Probability of 0.4 that an interviewee gets one of his preferred timeslot.

Probability that each of the 5 interviewees gets one of their preferred time slots :

Using the multiplication rule of independence :

0.4 * 0.4 * 0.4 * 0.4 * 0.4 = 0.4^5 = 0.01024

0.01024 * 100% = 1.024%

Answer:

Step-by-step explanation:

take 35 degree as reference angle

using cos rule

cos 35=adjacent/hypotenuse

0.81=x/78

78*0.81=x

63.18=x

63.2=x

The value of x for the given triangle is x = 63.2.

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.

Given that the angle is 35 and the adjacent side is x and the hypotenuse is 78.

The measure of value x will be calculated below,

cos(35)°=adjacent/hypotenuse

0.81=x/78

Multiply the value by 0.81 by 78 and solve for x,

78 x 0.81=x

63.18=x

63.2=x

Therefore, the value of x will be 63.2.

Answer:

1. Tallahassee Jellyfish is the better offer 2. (5, 2000000)

Step-by-step explanation:

1.

Since g = 8, p1 = 400000 * 8 = $3,200,000

and p2 = 1250000 + 150000 * 8 = $2,450,000

2.

400,000g = 1,250,000 + 150,000g

250,000g = 1,250,000

g = 1,250,000 / 250,000 = 5.

at g=5, you can use either graph to find the y value.

400,000 * 5  = $2,000,000

Answer:

x = 6 1/4

y = 3 3/4

Step-by-step explanation:

let 'x' = gallons of 6% nitrogen

let 'y' = gallons of 30% nitrogen

system of equations:

x + y = 10;  let y = 10-x

6x + 30y = 10(15)

substitute '10-x':

6x + 30(10-x) = 150

6x + 300 - 30x = 150

-24x = -150

x = 6 1/4

y = 3 3/4

Step-by-step explanation:

point (6, -5) => x = 6, y = -5

r =√6² +(-5)² = √(36+25)=√61

the exact value of :

cos 0 = x/r = 6/√61 = 6/61 √61

csc 0 = r/y = √61/(-5) = -1/5 √61

tan 0 = y/x = -5/6

Answer:

Solutions given:

(6,-5)=(x,y)

r=[tex]\sqrt{6²+(-5)²}=\sqrt{61}[/tex]

Now

Sin θ=[tex] \frac{y}{r}[/tex]=[tex] \frac{-5}{\sqrt{61}}[/tex]

Cosθ=[tex] \frac{x}{r}[/tex]=[tex] \frac{6}{\sqrt{61}}[/tex]

Step-by-step explanation:

Given that

There is 8 new graduates are hired

2 of the graduates are bill and cathy

And, each one is assigned on random basis

We need to find out the probability

So,

= (2) (7!) ÷ (8!)

= (2) ÷ (8)

= 1 ÷ 4

Answer:

x = 10

Step-by-step explanation:

Given:

Arc LM = 13x - 10

Arc MN = 7x - 10

Required:

Solve for x

Solution:

Recall: half a circle = 180°

Therefore,

Arc LM + Arc MN = 180°

13x - 10 + 7x - 10 = 180

Add like terms

20x - 20 = 180

20x - 20 + 20 = 180 + 20

20x = 200

20x/20 = 200/20

x = 10
