Answer:

84 students

Step-by-step explanation:

We know that the ratio of boys to girls is 4 : 3, and we know that the actual number of boys is 48, so let's set up a proportion:

\frac{4boys}{3girls} =\frac{48boys}{x girls}, where x is the number of girls in the club

Cross-multiply:

4x = 48 * 3 = 144

x = 144/4 = 36

Thus, there are 36 girls in the club.

Don't forget to check back with the question! It's asking for the total number of students, so we need to add 36 to 48:

36 + 48 = 84

Therefore, our answer is 84 students.

Melinda can paint 1/4 of a wall in the same time that Desiree can paint 2/5 of a wall. How much of a wall will Melinda have pain
Harlamova29_29 [7]

Answer:

Melinda will paint 5/8 part of a wall when Desiree has finished painting 1 wall.

Step-by-step explanation:

It is given that:

Melinda can paint 1/4 of a wall in the same time that Desiree can paint 2/5 of a wall.

Let 't' be the time taken by Melinda and Desiree to paint 1/4 and 2/5 of a wall respectively.

Now the time taken by Desiree to paint 1 wall will be:

2/5 of wall= t

1 wall= (5/2) t

Now in this time ( i.e. 5/2 t) the part of a wall painted by Melinda will be:

As Melinda takes--  t time to paint= 1/4 of a wall

                              5/2 t she will paint= (5/2)×(1/4) of a wall= (5/8) of a wall.

Hence Melinda will paint 5/8 part of a wall when Desiree has finished painting 1 wall.

Suppose a research paper states that the distribution of the daily sea-ice advance/retreat from each sensor is similar and is ap
strojnjashka [21]

Answer:

The value of the parameter is λ is 0.03692

Step-by-step explanation:

Consider the provided function.

f(x) = 0.5\lambda e^{-\lambda |x|} for −∞ < x < ∞.

It is given that standard deviation is given as 38.3 km.

Now we need to calculate the value of parameter λ.

The general formula for the probability density function of the double exponential distribution is: f(x)=\frac{e^{-|\frac{x-\mu}{\beta}|}}{2\beta}

Where μ is the location parameter and β is the scale parameter.

Compare the provided equation with the above formula we get.

\lambda=\frac{1}{\beta} and μ = 0.

Standard deviation = √2β

S.D=\sqrt{2} \beta\\\beta=\frac{38.3}{\sqrt{2}}\\\beta=27.08219

Now substitute the value of β in \lambda=\frac{1}{\beta}.

\lambda=\frac{1}{27.08219}=0.03692

Hence, the value of the parameter is λ is 0.03692
