Answer:

1.33333333333 cm

Step-by-step explanation:

It's pretty simple:

Based on the question, we know that 24cm = 18 miles

Therefore we can do a three simple rule

If 24 cm = 18 miles

x cm = 1 mile

x = $\frac{24 * 1}{18}$

x = $1.33333333333 cm$

. The sandwich shop offers 8 different sandwiches. Jamey likes them all equally. He picks one randomly each day for lunch. Durin

Margarita [4]

Answer:

Step-by-step explanation:

From the given information:

A sandwich shop offers eight types of sandwiches, and Jamey likes all of them equally.

The probability that Jamey picks any one of them is 1/8

Suppose

X represents the number of times he chooses salami

Y represents the number of times he chooses falafel

Z represents the number of times he chooses veggie

Then X+Y+Z ≤ 5 and;

5-X-Y-Z represents the no. of time he chooses the remaining

8 - 3 = 5 sandwiches

However, the objective is to determine the P[X=x,Y=y,Z=z] such that 0≤x,y,z≤5

So, since he chooses x no. of salami sandwiches with probability (1/8)x

and y number of falafel with probability (1/8)y

and for z (1/8)z

Therefore, the remaining sandwiches are chosen with probability $\dfrac{5}{8} (5-x-y-z)$

So. these x days, y days and z days can be arranged within five days in

$= \dfrac{5!}{x!y!z!(5-x-y-z)!}$

Thus;

$P[X=x,Y=y,Z=z]= \dfrac{5!}{x!y!z!(5-x-y-z)} \times \dfrac{1}{8}x*\dfrac{1}{8}y* \dfrac{1}{8}z* \dfrac{5}{8}(5-x-y-z)$

since 0 ≤ x, y, z ≤ 5 and x + y + z ≤ 5.

The distribution is said to be Multinomial distribution.

Answer:

For $\frac{6}{25} = \frac{d}{30}$ , d = 7.2

Step-by-step explanation:

Here, the given expression is $\frac{6}{25} = \frac{d}{30}$

To find the value of the variable d :

$\frac{6}{25} = \frac{d}{30} \implies d = \frac{6}{25} \times 30$

or, $d = \frac{180}{25} = \frac{36}{5 } = 7.2$

Hence, for $\frac{6}{25} = \frac{d}{30}$ , d = 7.2

Which expression is equivalent to sec^2xcot^2x?

Lady_Fox [76]

$\sec x=\dfrac{1}{\cos x}\\\\\cot x=\dfrac{\cos x}{\sin x}$

$\sec^2x\cot^2x=\dfrac{1}{\cos^2x}\cdot\dfrac{\cos^2x}{\sin^2x}=\dfrac{\cos^2x}{\cos^2x\sin^2x}=\dfrac{1}{\sin^2x}$

united services and supplies reports net income of $100000 and cost of goods of $353000. If US&S's gross profit rate was 30%

deff fn [24]

Answer:

Net sales is $ 504285.71

Step-by-step explanation:

We have the following:

Let net sales be x.

Net sales - Cost of goods sold = Gross profit

We replace and we are left with:

x - $ 353000 = x * 30%

x - $ 353000 = 0.30 * x

x - 0.30 * x = $ 353000

0.7 * x = $ 353000

x = $ 353000 / 0.7

x = $ 504285.71

Therefore, net sales is $ 504285.71
