Answer:

12.303 feet is your answer.

Step-by-step explanation:

There are 30.48 cm in 1 foot.

Divide 375 with 30.48:

375/30.48 = ~12.303

12.303 feet is your answer.

A baker knows that the daily demand for strawberry pies is a random variable that follows the normal distribution with a mean of

Elan Coil [88]

The demand that has an 8% probability of being exceeded is 38.1230 .

<h3>What is probability?</h3>

Probability is the aspect of mathematics that focus on the occurrence of a random event.

This is calculated below:

The normal random variable having the mean is been given as :

(Mu = 31.8)

The standard deviation is been given as ( sd = 4.5)

Then in making our calculation, we will need to make use of the formular below:

$\\Z= (X - Mu) / sd = (X - 31.8) / 4.5$

But we know that going with the probability of 0.08

where k = 1.4051

P (Z > 1.4051)

k = 1.4051

we can have the expression for k as $[(X - 31.8) / 4.5]$

This can be simplified as:

X = 4.5 (1.4051) + 31.8 = 38.1230.

Therefore, the demand that has an 8% probability of being exceeded is 38.1230 .

The cell phone carrier had 250 subscribers before the strategy was introduced. After the new strategy is introduced, the number of staffs increased by a factor of 1.4.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let f(t) represents the number of subscribers and t represents the time in months. Hence:

$f(t) = 250(1.4)^t$

a = 250, b = 1.4

The cell phone carrier had 250 subscribers before the strategy was introduced. After the new strategy is introduced, the number of staffs increased by a factor of 1.4.

Which is the equation of an ellipse with directrices at x = 14 and foci at (2.0) and (-2, 0)?

Reil [10]

Answer:

$\dfrac{x^2}{8}+\dfrac{y^2}{4}=1$

Step-by-step explanation:

The relationship between the focus, directrix, and semi-major axis is ...

foci are ±ae

directrices are ±a/e

where "a" is the length of the semi-major axis and e is the eccentricity.

Using the given focus and directrix locations, we have ...

ae = 2

a/e = 4

When we multiply these equations, we have ...

(ae)(a/e) = (2)(4)

a^2 = 8

This is the denominator of the x^2 term in the equation for an ellipse:

x^2/a^2 + y^2/b^2 = 1

_____

We can find b^2 from ...

ae = √(a^2 -b^2)

b^2 = (a^2 -(ae)^2) = 8 -2^2 = 4

So, our ellipse equation is ...

x^2/8 +y^2/4 = 1 . . . . . . matches the first choice

A MILKMAN SOLD TWO OF HIS BUFFALOES FOR RS.20,000. EACH ON ONE HE MADE A GAIN OF 5% AND ON THE OTHER A LOSS OF 10%. FIND HIS OVE

Sveta_85 [38]

Selling price of 1st buffalo +Selling price of 2nd buffalo=20000
profit for 1st buffalo=0.05 of cost price of 1st buffalo
loss for 2nd buffalo=0.1 of cost price of 2nd buffalo
1.05(cost price of 1st buffalo)+(0.9)cost price of 2nd buffalo=20000
the buffalo must cost must be same = x (say)
1.05x+0.9x=20000
1.95x=20000
x=10256.41
2x=20512.82
profit=20512.82-20000=512.82
profit %=2.56410 %
