To find the area of the sas triangle with side lengths 29 and 36 and included angle 62 degrees.

Area of the sas triangle with side lengths 29 and 36 and included angle 62 degrees is 459.36.

A triangle's feature known as SAS, or "Side, Angle, Side," has two sides and an angle that are both known.

The space occupied between the sides of the SAS triangle in a plane can thus be calculated with the use of the SAS triangle area formula.

The formula to find area of SAS triangle is:

Area = ½ ab Sin C = ½ × 29 × 36 × sin 62

Thus, Area = 522 × sin 62 = 522 × 0.88 = 459.36

Hence the answer is, Area of SAS triangle with side lengths 29 and 36 and included angle 62 degrees is 459.36.

The solution for f(3) in the function when the function f(x) = 0.75(10 - x) + 1 is 6.25

From the question, we have the following equation that can be used in our computation:

f(x) = 0.75(10-x)+1

To make the equation legible, we need to rewrite it

So, we have the following representation

f(x) = 0.75(10 - x) + 1

Also from the question, we have

f(3)

This means that the value of x is 3, and we calculate f(x) when x = 3

Substitute the known values in the above equation, so, we have the following representation

f(3) = 0.75(10 - x) + 1

So, we have the following equation

f(3) = 0.75(10 - 3) + 1

There are constants to add or subtract to both sides of the equation

Also, there are factors to multiply or divide from both sides of the equation

So, we have the following representation

f(3) = 0.75 * 7 + 1

Solving further, we have

f(3) = 5.25 + 1

Evaluate the sum

f(3) = 6.25

Hence, the solution is 6.25

Answer:  E has no solution

Step-by-step explanation: It is a contradiction

Answer:

Only cheddar 10 pounds

Only swiss 6 pounds

Use the equation to find out different combinations.

3x + 5y = 30

For example, 1 pound of cheddar and 5.4 pounds of swiss.

Step-by-step explanation:

Let x = cheddar

Let y = swiss

3x + 5y = 30

If we only wanted cheddar let y be 0

3x =30  Divide both sides by 3

x = 10

You can buy 10 pounds of cheddar.

If we only wanted swiss let x be 0

5y = 30  Divide both sides by 5

y = 6

You can buy 6 pounds of swiss.

1 pound of cheddar:

3(1) + 5y = 30  Subtract 3 from both sides

5y = 27  Divide both sides by 5

y = 5.4

Answer:

Step-by-step explanation:

You want the domain of the function F(x) = 1.

The domain of a function is the set of values of the independent variable for which the function is defined. The function F(x) is defined for all possible values of x, so its domain is all real numbers.

At the 0.05 level of confidence, there is enough data to say that Gentle Ben's blood glucose is higher than 85 mg/100 ml.

A probability distribution that is symmetric about the mean is the normal distribution, also referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean. The normal distribution appears as a "bell curve" on a graph. Data are symmetrically distributed and skew-free in a normal distribution. As one moves away from the center, values start to taper off and the majority of values are concentrated in this area. In a normal distribution, the mean, mode, and median are identical measures of central tendency.

Multiply the second equation by 3

Answer:

 D. Multiply the second equation by 3. The solution is x = 12, y = 10.

Step-by-step explanation:

You want the multiplier for the elimination of the y-variable in the system of equations x +3y = 42; 2x -y = 14.

The coefficients of y are +3 and -1, so multiplying the second equation by 3 will make it the opposite of the former. Then their sum is zero, which is what you want when eliminating the y-variable.

Multiplying the second equation by 3 and adding the first gives ...

  3(2x -y) +(x +3y) = 3(14) +(42)

  7x = 84 . . . . . . . . . simplify. Note the y-variable has been eliminated.

  x = 12 . . . . . . . . . divide by 7

  2(12) -y = 14 . . . . substitute for x in the second equation

The equation of linear function is y=x-1.

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

The given values are

x=1, y=0

x=2, y=1

x=3, y=2

x=4, y=3

The table represents that for the value of x the value of y is x-1,

Since for any two points from the table, let (1,0) and (2,1)

The slope = 2-1/1-0 = 1

And the interception of y is 0 when x=1

Therefore, the equation of the function can be written as,

y=x-1

a) About 4.16% of test takers earn a score less than 500 on the GRE Chemistry test.

b) About 96.64% of test takers earn a score greater than or equal to 900 on the GRE Chemistry test.

c) The estimated score at the 99th percentile on the GRE Chemistry test is approximately 954.512.

To answer these questions, we'll use the properties of the normal distribution and the given mean and standard deviation.

(a) To find the percentage of test takers who earn a score less than 500 on the GRE Chemistry test, we need to calculate the cumulative probability up to the score 500.

z-score = (X - mean) / standard deviation

where X is the score we are interested in.

z-score = (500 - 694) / 112

z-score ≈ -1.732

Now, we look up the cumulative probability for a z-score of -1.732 in the standard normal distribution table or use a calculator to find that the cumulative probability is approximately 0.0416 or 4.16%.

So, about 4.16% of test takers earn a score less than 500 on the GRE Chemistry test.

(b) To find the proportion of test takers who earn a score greater than or equal to 900, we need to calculate the cumulative probability from 900 to positive infinity.

z-score = (X - mean) / standard deviation

where X is the score we are interested in.

z-score = (900 - 694) / 112

z-score ≈ 1.839

Now, we look up the cumulative probability for a z-score of 1.839 in the standard normal distribution table or use a calculator to find that the cumulative probability is approximately 0.9664 or 96.64%.

So, about 96.64% of test takers earn a score greater than or equal to 900 on the GRE Chemistry test.

(c) To estimate the score at the 99th percentile on the GRE Chemistry test, we need to find the value that separates the lowest 99% of the scores from the highest 1%.

We use the z-score formula to find the z-score corresponding to the 99th percentile:

z-score = invNorm(0.99)

z-score ≈ 2.326

Now, we use the z-score to find the score corresponding to the 99th percentile:

X = mean + (z-score * standard deviation)

X = 694 + (2.326 * 112)

X ≈ 694 + 260.512

X ≈ 954.512

So, the estimated score at the 99th percentile on the GRE Chemistry test is approximately 954.512.

We list the operations done between two functions below:

In this problem we find three functions, two of them defined by quadratic equations (f(x), g(x)) and the other defined by a linear equation (h(x)). There are five operations that can be used b two functions:

Now we proceed to determine the result of each operation:

Case 1:

g(x) / h(x) = (4 · x² + 2 · x - 1) / (2 · x - 3)

Case 2:

h(x) - g(x) = (2 · x - 3) - (4 · x² + 2 · x - 1)

h(x) - g(x) = - 4 · x² - 2

Case 3:

h(f (x)) = 2 · (3 · x² + 2) - 3

h(f (x)) = 6 · x² + 1

Case 4:

f(x) + g(x) = (3 · x² + 2) + (4 · x² + 2 · x - 1)

f(x) + g(x) = 7 · x² + 2 · x + 1

Case 5:

h(f(x)) = 6 · x² + 1

h(f(2)) = 6 · 2² + 1

h(f(2)) = 25

Case 6:

f(h(x)) = 3 · (2 · x - 3)² + 2

f(h(x)) = 3 · (4 · x² - 12 · x + 9) + 2

f(h(x)) = 12 · x² - 36 · x + 29

f(h(3)) = 12 · 3² - 36 · 3 + 29

f(h(3)) = 29

Case 7:

g(x) + h(x) = (4 · x² - 12 · x + 9) + (2 · x - 3)

g(x) + h(x) = 4 · x² - 10 · x + 6

g(2) + h(2) = 4 · 2² - 10 · 2 + 6

g(2) + h(2) = 2

Case 8:

2 · f(x) - g(x) = 2 · (3 · x² + 2) - (4 · x² + 2 · x - 1)

2 · f(0) - g(2) = 2 · (3 · 0² + 2) - (4 · 2² + 2 · 2 - 1)

2 · f(0) - g(2) = 4 - 19

2 · f(0) - g(2) = - 15
