Based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).

Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.

When the sample size is less than 30, the formula which is used is,

[tex]\overline x\pm t.\dfrac{s}{\sqrt n}[/tex]

Here, n is the sample size, [tex]\overline x[/tex] is the sample mean, s is the standard deviation.

Economist, takes an SRS of 12 gas stations. The sample size for the given problem is 12,

[tex]n=12[/tex]

Thus, degree of freedom,

[tex]df=12-1\\df=11[/tex]

In the t table, for df 11, the value of t is 1.796.

An economist studying fuel costs wants to estimate the mean price of gasoline in her state on a certain day.

On that day, she takes an SRS of 12 gas stations and finds the sample mean price (in dollars per gallon) is,

[tex]\bar x=2.29[/tex]

With a standard deviation of

[tex]s_x=0.20[/tex]

Put the values in the above formula,

[tex]2.29\pm 1.796.\dfrac{0.20}{\sqrt 12}\\2.29\pm 0.1037\\2.29+0.1037=2.3937\\2.29- 0.1037=2.1863[/tex]

Thus, based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).

24 and 42 represent one combination, but 2 permutations. Thus, the number of two-digit numbers that can be made with the digits 2, 4, 6, and 8 is: Therefore, 12 two-digit numbers can be made with the digits 2, 4, 6, and 8.

Step-by-step explanation:

please mark this answer as brainliest, leave a 5-start rating, and give a thanks

The number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.

The given digits are 4, 6 and 8.

We know that, P(n, r)= n!/(n-r)!

Here, n=3 and r=2

Now, 3!/(3-2)!

= 3×2

= 6

Using C(n, r)= n!/r!(n-r)!

Now, 3!/2!(3-2)!

= 3

So, 6×3

= 18

Therefore, the number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.

Answer:

Antonio is the right one

Answer:

∠ A = 123°

Step-by-step explanation:

The central angle A is equal to the arc that subtends it , so

∠ A = arc DE = 5x - 2

The angles subtended by the radii and tangents of a circle are supplementary

2x + 7 + 5x - 2 = 180 ← Antonio is correct

7x + 5 = 180 ( subtract 5 from both sides )

7x = 175 ( divide both sides by 7 )

x = 25

Then

∠ A = 5 - 2 = 5(25) - 2 = 125 - 2 = 123°

Answer:

1/12

Step-by-step explanation:

Total choices = 9, vowels = I, E, I = 3

Hence, P (vowel) = 3/9 = 1/3

Since you do not replace it, new total = 8 and number of Ts = 2

Hence, P (T) = 2/8 = 1/4

As these events are dependent and T is picked after vowel,

total probability = 1/3 x 1/4 = 1/12

Answer:

Cantidad de adultos= 975

Step-by-step explanation:

Dada la siguiente información:

Cantidad total de personas= 1.500

Proporición de niños y niñas= 0,35

Proporción de adultos= (1 - 0,35)= 0,65

Para calcular la cantidad de adultos, debemos utilizar la siguiente formula:

Cantidad de adultos= cantidad total de personas*proporción de adultos

Cantidad de adultos= 1.500*0,65

Cantidad de adultos= 975

Given:

The quadratic equation is:

[tex]6x^2-x-2=0[/tex]

To find:

The nature of the solutions by using the discriminant.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then its discriminant is:

[tex]D=b^2-4ac[/tex]

If D<0, then both roots are complex.

If D=0, then both roots are real and equal.

If D>0, then both roots are real and distinct.

We have,

[tex]6x^2-x-2=0[/tex]

Here, [tex]a=6,b=-1,c=-2[/tex]. So, the value of the discriminant is:

[tex]D=(-1)^2-4(6)(-2)[/tex]

[tex]D=1+48[/tex]

[tex]D=49[/tex]

Since [tex]D>0[/tex], then both roots are real and distinct.

Hence, the discriminant of the given quadratic equation is 49 and both roots are real and distinct.

Suppose that we have x and y as the integers( x is bigger than y ).

As the question told :

x = 3y + 12

_________________________________The integers have a sum of 92 which means :

x + y = 92 ==》( 3y + 12 ) + y = 92

==》 4y + 12 = 92

==》 4y = 92 - 12

==》 4y = 80

==》 y = 20

☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆

x + y = 92 ==》x + 20 = 92

==》x = 92 - 20

==》x = 72

Answer:

The two integer is, y = 20 and

                               x = 72

Step-by-step explanation:

Integer, positive or negative whole number, or 0 The integers are created using the counting numbers 1, 2, 3,... and the subtraction function. The result of subtracting a counting number from itself is zero; for example, 4 4 = 0. When you subtract a greater number from a smaller number, you get a negative whole number; for example, 2 3 = 1. Every integer may be deduced from the counting numbers in this fashion, resulting in a set of numbers that can be subtracted.

As the question told :

x = 3y + 12

The integers have a sum of 92 which means :

x + y = 92

        = ( 3y + 12 ) + y = 92

        = 4y + 12 = 92

        =  4y = 92 - 12

        =  4y = 80

     y = 20

Then, x + y = 92

       x + 20 = 92

                x = 92 - 20

                x = 72

The two integer is, y = 20 and x = 72

Answer:

aₙ = 31n -  5

Step-by-step explanation:

The terms of your sequence are.

26, 57, 88, …

This is an arithmetic sequence, because there is a constant difference of 31 between consecutive terms.

The explicit formula for the nth term of an arithmetic sequence is

aₙ = a₁ + d(n - 1 )

a₁ is the first term, and d is the difference in value between consecutive terms. Thus,  

aₙ = 26 + 31(n - 1) = 26 + 31n - 31

aₙ = 31n - 5

The explicit rule for the arithmetic sequence is aₙ = 31n - 5.
