The weight of coffee worth $10 to be added to mixture to worth $6 a pound is 15 pounds the mixture will be  15 pounds

Let the weight of coffee worth $10 to be added to mixture be x pounds

The weight of coffee worth $4 to be added to mixture is 30 pounds

We want a mixture that worth $6 a pound

The weight of mixture of coffee worth $ 6 is the sum of $10 coffee and $4 coffee

    = x + 30

From the above equation we can form a linear equation

              X 10 + 30 ×4 = (x+ 30) 6

    10x + 120= 6x +180

    10x-6x= 180 -120

         4x = 60

               X= 15

Hence, the weight of coffee worth $10 to be added to mixture to worth $6 a pound is 15 pounds

The answers are below.

a) (fog)(x) = f(g(x)) = 2 - ( 3x² +x+5) = -3x² - x - 3

b) (gof)(x) = g(f(x)) = 3*(2 - x)² + (2 - x) +5 = 3x² - 13x + 19

a) (fog)(2) =  -3x² - x - 3 = -3*4 - 2 - 3 = -12 - 2 - 3 = -17

b) (gof)(2) = 3x² - 13x + 19 = 3*4 - 13*2 + 19 = 12 - 26 + 19 = 5

Just replace evaluate the function g(x)= 3x² +x+5 insode of the function f(x) = 2 - xfor the first one.

a) (fog)(x) = f(g(x)) = 2 - ( 3x² +x+5) = -3x² - x - 3

b) (gof)(x) = g(f(x)) = 3*(2 - x)² + (2 - x) +5 = 3x² - 13x + 19

ok, now that you have these two values, just evaluate the equations in x = 2 to get the rest.

a) (fog)(2) =  -3x² - x - 3 = -3*4 - 2 - 3 = -12 - 2 - 3 = -17

b) (gof)(2) = 3x² - 13x + 19 = 3*4 - 13*2 + 19 = 12 - 26 + 19 = 5

These are the outcomes when we evaluate the compositions in x = 2.

Answer:The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)

Step-by-step explanation:

The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)

The equation of a circle usually takes the form;

(x-a)² + (y-b)² = r²

where a and b are x- and y- coordinates of the center of the circle.

In this scenario, the center is at the origin (0,0).

In essence, the points on the circle which have an x-coordinate of 1 can be evaluated as follows;

(1-0)² + (y - 0)² = 4²

1 + y² = 16.

y² = 15

y = ±√15.

The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)

The total number of student present in the class is 15.

One-third of the students choose to work on an essay.

Let

x = the total number of student in the class

Therefore,

student that takes essay = 1 / 3 x

One-half of the remaining students choose to read.

Therefore, the expression is as follows

student that choose to read = 1 / 2(x - 1 / 3 x)  = 1 / 2( 3x - x/ 3) = 1 / 2(2 / 3 x) = 2 / 6 x = 1 / 3x

The remaining 5 students work on vocabulary.  Therefore, the expression is as follows:

Student that works on vocabulary = x - 1 / 3 x - 1 / 3 x

5 =  x - 1 / 3 x - 1 / 3 x

5 = 3x- x - x / 3

5 = x / 3

x = 15

Therefore,

the student present in the class = 1 / 3 (15) +  1 / 3(15) + 5

the student present in the class = 5 + 5 + 5

the student present in the class = 15

The values of x and m∠R are 15 and 50 respectively.

From the information given, we have the following parameters;

Now, let's equate the angles

m ∠ R  = m ∠ S

3x + 5 = 5x - 25

collect like terms

3x - 5x = -25 - 5

subtract like terms

-2x = - 20

Make 'x' the subject

x = -30/ -2

x = 15

But m ∠ R = 3x + 5 = 3(15) + 5 = 45 + 5  = 50

Thus, the values of x and m∠R are 15 and 50 respectively.

The range and domain for the exponential function and logistics function are Expotentioal function : Domain= (2,  infinity )

Exponential function:

An exponential function is a mathematical function of the following form: f ( x ) = a x. where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.

Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent. An example of an exponential function is the growth of bacteria. Some bacteria double every hour.

In exponential notation, a number usually is expressed as a coefficient between one and ten times an integral power of ten, the exponent. To express a number in exponential notation, write it in the form: c × 10n, where c is a number between 1 and 10 (e.g. 1, 2.5, 6.3, 9.8) and n is an integer (e.g. 1, -3, 6, -2

Definition of logarithmic function: a function (such as y = log x or y = ln x) that is the inverse of an exponential function (such as y = ax or y = ex) so that the independent variable appears in a logarithm.

When b > 0 and b 1, an exponential function has the form f(x) = bx. The base is b, and the exponent is x, just like in any exponential expression. The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour.

Lower limit of 95% confidence interval is  0.464 and upper limit of 95% confidence interval is 0.594

What is Z value of 95% confidence interval and how to find 95% confidence interval?

A Z value is a numerical measure of how far is an individual score is from the mean score, within a normal distribution.

The Z value for 95% confidence interval is Z=1.96.

Let p the  estimated proportion of people in favor of a proposition and n be the sample size, n = 225

Marginal error = [tex]Z\sqrt{\frac{p(1-p)}{n} }[/tex]

Lower limit of 95% confidence interval = Z - Marignal error           

Upper limit of 95% confidence interval = Z + Marginal error

Given that in a poll of 225 randomly selected U.S. adults, 119 said they favored a new proposition,

The estimated proportion of people favored a new proposition is, p =[tex]\frac{119}{225}[/tex]

Then, p = 0.529

Marginal Error = [tex]Z\sqrt{\frac{p(1-p)}{n} } = 1.960\sqrt{\frac{0.529(1-0.529)}{225} }[/tex] = 0.065

Therefore,

Lower limit of 95% confidence interval   =0.529-0.065  = 0.464    

Upper limit of 95% confidence interval = 0.529+0.065 = 0.594

And the 95% confidence interval would be given (0.464,0.594).
