First, you will have to substitute the values
Here is the info. we already have
c=8
Expression: 7/8 x c
Now let's substitute...
7/8 x 8
You can multiply the two numbers to get 56/8 or you can use the method of crossing the two eights out, which is quicker.
Otherwise, 56/8 is 7
So the answer is 7

At c=8:

7/8* c
= 7/8* (8)
= 7 (because 8 and 8 cancel out)

The final answer is 7~

Sedbober [7]

Answer: 0.8313

Step-by-step explanation:

As per given we have,

$\mu=15.5$ $\sigma= 3.6$

Also, the distribution of the number of suitcases that get lost each week on a certain route is approximately normal.

Since , $z=\dfrac{x-\mu}{\sigma}$

z-score corresponds to x= 10: $z=\dfrac{10-15.5}{3.6}\approx-1.53$

z-score corresponds to x= 20: $z=\dfrac{20-15.5}{3.6}=1.25$

P-value = $P(10$

$=P(z$

Hence, the probability that during a given week the airline will lose between 10 and 20 suitcases = 0.8313

At a campground, a rectangular fire pit is 3 feet by 2 feet. What is the area of the largest circular fire that

AysviL [449]

The area of the largest circular fire pit is 452 square inches.

Explanation:

Given that at a campground, a rectangular fire pit is 3 feet by 2 feet

The radius is given by 1 feet.

<u>Area:</u>

The area of the largest circular fire is given by

$A=\pi r^2$

Substituting the values in the formula, we get,

$A=(3.14)1^2$

$A=3.14 \ ft^2$

Thus, the area of the largest circular fire is 3.14 square feet.

<u>To convert feet to inches:</u>

The feet can be converted into inches by multiplying by 12.

Thus, we have,

$1 \ft= 12 \ inches$

Hence, we have,

$Area= 3.14\times 12^2$

Simplifying,we get,

$Area= 3.14\times144$

$Area=452.16 \ in^2$

Rounding off to the nearest square inch.

Thus, we have,

$Area= 452 \ in^2$

Thus, the area of the largest circular fire pit is 452 square inches.

Determine whether f(x)=-4(x+3)^2-5 has a maximum or a minimum value, then find that value

Leto [7]

Answer:

Yes it has

Step-by-step explanation:

From my perspective.........

f(x) = -4(x + 3)² - 5

f(x) = -4(x + 3)(x + 3) - 5

f(x) = -4(x² + 6x + 9) - 5

f(x) = -4x² - 24x - 36 - 5

f(x) = -4x² - 24x - 41

Dy/dx = -8x - 24

At minimum Dy/dx = 0

-8x - 24 = 0

-8x = 24

x = 24/-8

x = -3

At minimum

y = -4x² - 24x - 41

y = -4(-3)² - 24(-3) - 41

y = -4(9) + 72 - 41

y = -36 + 72 - 41

y = 36 - 41

y = -5
