Convert 39°C to degrees Fahrenheit.

posledela

Given a temperature C in celsius, you can convert it to Fahrenheit by using the formula

$F=32 + \dfrac{9C}{5}$

In your case C=39, so you have

$F = 32 + \dfrac{9\cdot 39}{5} = 32+70.2=102.2$

A number is picked randomly in the range [0,7]. What is the probability that the number picked is between 3 and 5? What is the p

emmasim [6.3K]

Answer:

(1) 0.125

(2) 0.125

Step-by-step explanation:

The total number of possible outcomes is:

N = 8

(1)

Compute the probability that the number picked is between 3 and 5 as follows:

Number of Favorable outcomes = 1

The probability is:

P (Number picked is between 3 and 5) = 1/8 = 0.125

Thus, the probability that the number picked is between 3 and 5 is 0.125.

(2)

The number usually picked appears to be in in the range [3,5], i.e. the numbers could be, {3, 4 or 5}.

Number of Favorable outcomes = n (Number < 4 and within [3, 5]) = 1

P (less than 4 ∩ within [3, 5]) = 1/8 = 0.125

Thus, the probability that the number picked is less than 4 knowing that the number usually picked appears to be in in the range [3,5] is 0.125.

WhiThree-fifths of the members of the Spanish club are girls. There are a total of 30 girls in the Spanish club.

vesna_86 [32]

Answer:

The total members in the Spanish Club = 50

Step-by-step explanation:

Let the total members in the Spanish Club = x

Now, number of girls in the club = 30

Three-fifths of the members are girls.

⇒ $(\frac{3}{5} )$ of total members x = 30

or, $(\frac{3}{5}) \times x = 30\\$

Now, solving for x, we get:

$x = 30 \times\frac{5}{3} = 50$

or, x = 50

Hence,the total members in the Spanish Club = 50
