Answer:

53.1°

Step-by-step explanation:

A rectangle triangle is formed, where 4/5 is the opposite side to θ and 3/5 is the adjacent side to θ (see figure attached).

From tangent definition:

tan θ = opposite/adjacent

tan θ = (4/5)/(3/5)

θ = tan^-1 (4/3)

θ = 53.1°

Work out the following, giving your answer in the simplest form <br> A) 4/7 divided by 1 3/4

Answer:

The answer to your question is 16/49

Step-by-step explanation:

Data

4/7 ÷ 1 3/4

Process

1.- Convert the mixed fractions into improper fractions

1 3/4 = (4 + 3) / 4 = 7/4

2.- Divide

4/7 ÷ 7/4 = 16/49

3.- Simplify

I think it is not possible to simplify.

4.- Also we can solve this problem by converting the division into a multiplication, just invert the second fraction.

4/7 x 4/7 = 16/49

The result is the same.

Answer:

B) 0.02

Step-by-step explanation:

<u>Use the Binomial Theorem</u>

$\displaystyle P(X=x)=\binom{n}{x}p^xq^{n-x}\\\\P(X=4)=\binom{30}{4}(0.30)^4(1-0.30)^{30-4}\\\\P(X=4)=\frac{30!}{4!(30-4)!}(0.30)^4(0.70)^{26}\\ \\P(X=4)=\frac{30!}{4!(26)!}(0.30)^4(0.70)^{26}\\ \\P(X=4)=\frac{30*29*28*27}{4*3*2*1}(0.30)^4(0.70)^{26}\\ \\P(X=4)=27405(0.30)^4(0.70)^{26}\\\\P(X=4)\approx0.0208$

We have the probability of success, $p=0.30$ , and the probability of failure, $q=1-0.30=0.70$ . The binomial coefficient, $\binom{n}{k}$ , represents the amount of possible combinations that $k$ items can be chosen out of $n$ items, with its respective formula $\frac{n!}{k!(n-k)!}$ .

Hence, the best choice for the probability that 4 students chosen at random from the class of 30 that want the next test to be on Monday will be option B, 0.02
