Answer:

30 Oranges!

Step-by-step explanation:

Given that for every 2 apples there are 3 oranges.

How many oranges would be there in a basket of 20 apples?

Since for every couple of apples we have 3 oranges we will calculate how many couples of apples are there in the basket.

Given there are 20 apples. This means that there are $\frac{20}{2}$ = 10 pairs of apples.

Since for one pair we have three oranges, for 10 pairs we would have 3 X 10 = 30 oranges.

Therefore, we can conclude that the number of oranges in the bigger basket would be 30.

5 is not a divisor of any of the dimensions of the given box, so selections A, C, D can't work.

Each of the dimensions of selection B is a divisor of a different dimension of the box, so ...
.. the correct choice is selection B) 7 × 9 × 12.

Consider the following probability distribution function of the random variable X which represents the number of people in a gro

Troyanec [42]

Answer:

(a) 3.55

(b) 3.45 and 1.86

(c) 0.25

(d) 0.016

Step-by-step explanation:

The random variable X denotes the number of people in a group (party) at a restaurant.

(a)

The formula to compute the mean is:

$\mu=\sum {x\cdot P(X=x)}$

Consider the Excel sheet attached.

The mean is, 3.55.

(b)

The formula to compute the variance is:

$\sigma^{2}=[\sum {x^{2}\cdot P(X=x)}]-(\mu)^{2}$

Consider the Excel sheet attached.

Compute the variance as follows:

$\sigma^{2}=[\sum {x^{2}\cdot P(X=x)}]-(\mu)^{2}\\\\=16.05-(3.55)^{2}\\\\=3.4475\\\\\approx 3.45$

The variance is, 3.45.

Compute the standard deviation as follows:

$\sigma=\sqrt{\sigma^{2}}\\\\=\sqrt{3.45}\\\\=1.85742\\\\\approx 1.86$

The standard deviation is, 1.86.

(c)

Compute the probability that the next party will be over 4 people as follows:

$P(X>4)=P(X=5)+P(X=6)+P(X=7)+P(X=8)\\\\=0.10+0.05+0.05+0.05\\\\=0.25$

Thus, the probability that the next party will be over 4 people is 0.25.

(d)

Compute the probability that the next three parties will each be over 4 people as follows:

It is provided that the three parties are independent.

P (Next 3 parties will be each over 4) = [P (X > 4)]³

$=(0.25)^{3}\\=0.015625\\\approx 0.016$

Thus, the probability that the next three parties will each be over 4 people is 0.016.

If f(x)=-3x+3, then f^-1 (x)=____ Please help

fgiga [73]

Answer:

y = (-x/3) +1 or y = (-1/3 * x) + 1

Step-by-step explanation:

For the inverse of a function, you invert the y and x positions.

In your case:

y = -3x+3

The inverted function is:

x = -3y+3

When you solve this for y, you get:

-3y = x-3

y = -x/3 +1

Need the answer asap !! #34 !!

Rus_ich [418]

Answer:

A) 46 mph

Step-by-step explanation:

Step 1: To find the speed, you need to find the distance and time to travel between Chicago and Cleveland.

Distance = 354 miles

Time = 9: 50 am to 5: 30 pm

Time = 7 hours 40 minutes

Step 2: Convert time to hours

1 hour = 60 minutes

40 minutes = 60/40 = 2/3 hours

Step 3: Find the speed

Speed = Distance/Time

Speed = 354/7 + 2/3

Speed = 1062/23

Speed = 46.17 miles per hour rounded off to 46 mph

Therefore, A is the correct answer.
