**Answer:**

The 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].

**Step-by-step explanation:**

**Given information:**

Sample size = 10

Sample mean = 12.2 mph

Standard deviation = 2.4

Confidence interval = 95%

At confidence interval 95% then z-score is 1.96.

The 95% confidence interval for the true mean speed of thunderstorms is

Where, is sample mean, z* is z score at 95% confidence interval, s is standard deviation of sample and n is sample size.

**Therefore the 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].**

Using **continuity concepts,** it is found that the function is **left-continuous at x = 1.**

-------------------------------

A **function f(x)** is said to be **continuous at x = a** if:

- If only , the function is
**left-continuous.**

- If only , the function is
**right-continuous.**

-------------------------------

The **piece-wise** definition of the **function ** is:

We have to **check the continuity** at the points in which the definitions change, that is,** x = 0 and x = 1.**

-------------------------------

At **x = 0:**

- The
**definition**at 0 is **Approaching x = 0 from the left**, we have values less than 0, thus:

**Approaching x = 0 from the right**, we have values greater than 0, thus:

Since the limits are equal, and also equal to the definition at the point, the function is **continuous at x = 0.**

-------------------------------

At **x = 1:**

- The
**definition**at 1 is

**Approaching x = 1 from the left**, we have values less than 1, thus:

**Approaching x = 1 from the right**, we have values greater than 1, thus:

To the right, the limit is different, thus, the function is only **left continuous at x = 1.**

**Answer:**

the function is continuous from the left at x=1 and continuous from the right at x=0

**Step-by-step explanation:**

a function is continuous from the right , when

when x→a⁺ lim f(x)=f(a)

and from the left when

when x→a⁻ lim f(x)=f(a)

then since the functions presented are continuous , we have to look for discontinuities only when the functions change

for x=0

when x→0⁺ lim f(x)=lim e^x = e^0 = 1

when x→0⁻ lim f(x)=lim (x+4) = (0+4) = 4

then since f(0) = e^0=1 , the function is continuous from the right at x=0

for x=1

when x→1⁺ lim f(x)=lim (8-x) = (8-0) = 8

when x→1⁻ lim f(x)=lim e^x = e^1 = e

then since f(1) = e^1=e , the function is continuous from the left at x=1

**Answer:**

27%

**Step-by-step explanation:**

The total books sold were 182 and the amount of books sold that were nonfiction hardcover were 49 as represented in the frequency table.

**To find the percentage we must divide the nonfiction hardcover by the total books.**

49/182≈0.269 or 0.27

Multiply the decimal by a 100 to change it into a percentage, so our answer is 27%.
