**Step-by-step explanation:**

The caffeine content (in mg) was examined for a random sample of 50 cups of black coffee dispensed by a new machine. The mean and the standard deviation were 110 mg and 7.1 mg respectively. Use the data to construct a 98% confidence interval for the mean caffeine content for cups dispensed by the machine. Interpret the interval!

**Answer:**

x = −π/2, x = π/2

**Step-by-step explanation:**

Given f(x) = 6x tan x and the interval −π/2 < x < π/2, we know that tan x has asymptotes in both extremes of the interval. To find the vertical asymptotes we evaluate the limit in the x-values we think asymptote can appear, in this case for x = −π/2 and x = π/2.

Then, x = −π/2 and x = π/2 are vertical asymptotes.

**Answer: Does not exist.**

**Step-by-step explanation:**

Since, given function, f(x) = 6x tan x, where −π/2 < x < π/2.

⇒ f(x) =

And, for vertical asymptote, cosx= 0

⇒ x = π/2 + nπ where n is any integer.

But, for any n x is does not exist in the interval ( -π/2, π/2)

Therefore, vertical asymptote of f(x) where −π/2 < x < π/2 does not exist.

f(7)=

f(-2)=

f(-4)=

The **value **of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 **respectively**.

A certain kind of **relationship **called a function **binds **inputs to essentially one output.

A function can be regarded as a **computer**, which is helpful.

The machine will only accept **specified **inputs, described as the function's **domain**, and will potentially produce one output for each input.

In other words, the **function **is a **relationship **between variables, and the **nature **of the relationship defines the function for example y = sinx and y = x +6 like that.

Given,

f(x)=2x-3

f(7) so put x = 7

f(7) = 2(7) - 3

**f(7) = 11**

Now,

f(-2) so put x = -2

f(-2) = -2×7-3

**f(-2) = -17**

Now,

f(-4) so put x = -4

f(-4)= -4×7-3

**f(-4) = -31 **

Hence,The **value **of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 **respectively**.

**Step-by-step explanation:**

f(x)=2x-3

now,

f(7)=2× 7-3

=14-3

=11

f(-2)='-2×7-3

= -14-3

b= -17

f(-4)= -4×7-3

= -28-3

= -31

Answer: 0.1397 ; 0.385

Step-by-step explanation:

Given the following :

Small engine population = 45% ; 10% fail

Medium engine population = 35% ; 12% fail

Large engine population = 20% ; 15% fail

Probability that a randomly chosen car fails emission test :

P(failure) = Σ(population % * failure %)

P(failure) = (45%*10%) + (35%*12%) + (20%*15%)

P(failure) = 0.045 + 0.042 + 0.03 = 0.117

B) what is the probability it is a car with a small engine

P = small engine cars with emission failure / total emission failure

= (0.45 × 0.1) / 0.117 = 0.045 / 0.117 = 0.3846

= 0.385

C (-squareroot13, -33.7 degrees)

E (-3,2)

Answer:

Step-by-step explanation:

The four sides of the quadrilateral touches the circle. This means that the opposite angles of the quadrilateral are supplementary.

It means that the sum of the angles is 180 degrees From the given diagram,

Angle B + angle R = 180

Angle B = 180 - 85

Angle B = 95 degrees

Angle D + angle I = 180

Angle D = 180 - 117

Angle D = 63 degrees

Answer

<B is 95, and <D is 63

Step-by-step explanation:

Opposite angles have sum 180, so angle of the B is 180-85=95, and angle of the D is 180-117=63

**Answer: (The first number are the years and the second are the amount of Komodo's) (0, 0) (1, 4) (2, 20) (3, 100) (4, 500) (5, 2,500)**

**Step-by-step explanation:**

**If there are 4 Komodo's in the first year because that's when they moved in, then there would be zero in the 0 year. **

**If they keep multiplying their population by 5 each year then for every year, you would multiply the existing population of that year by 5**

**Starting at year 1 which is (1, 4) multiply that by 5 to get 20 and so on to get the function.**

**I hope this helps!**
