A) you must plug in 50 for variable F and solve for C

C= $\frac{5}{9}$ (50-32)
C= $\frac{5}{9}$ (18)
C= 10
50 degrees fahrenheit is equal to 10 degrees celsius

B) you must solve the equation for F

C= $\frac{5}{9}$ (F-32)
C/ $\frac{5}{9}$ =F-32
C/ $\frac{5}{9}$ +32=F
F= C/ $\frac{5}{9}$ +32

dividing by a fraction is the same as multiplying buy its reciprocal so it can also be written as

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

now you just plug in 50 for the variable C in the new equation

F= $\frac{9}{5}$ (50) +32
F= 90 + 32
F= 122

50 degrees celsius is equal to 122 degrees fahrenheit

hope this helped!

The length of a suitcase is 36 inches . The diagonal of the suitcase is about 51 inches . What is the width of the suitcase ,rou

Mrrafil [7]

<u>Given</u>:

The length of a suitcase is 36 inches.

The diagonal of the suitcase is about 51 inches.

We need to determine the width of the suitcase.

<u>Width of the suitcase:</u>

The width of the suitcase can be determined using the Pythagorean theorem.

Thus, we have;

$d^2=l^2+w^2$

where d is the diagonal, l is the length and w is the width.

Substituting the values, we get;

$51^2=36^2+w^2$

Squaring the terms, we have;

$2601=1296+w^2$

Subtracting both sides by 1296, we get;

$1305=w^2$

Taking square root on both sides, we get;

$36.12=w$

Rounding off to the nearest inch, we get;

$36=w$

Thus, the width of the suitcase is 36 inches.

lysha is at a local library with her best friend. they've noticed a lot of cute boys in the library, and alysha bets that of the

Annette [7]

Using the binomial distribution, there is a 0.1201 = 12.01% probability that Alysha will win the bet.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

For this problem, the parameters are given as follows:

n = 20, p = 0.5.

She wins the bet if there are 12 boys, hence the probability is P(X = 12), found as follows:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 12) = C_{20,12}.(0.5)^{12}.(0.5)^{8} = 0.1201$

0.1201 = 12.01% probability that Alysha will win the bet.
