In cyclic quadrilateral PQRS,
ICE Princess25 [194]

The largest angle of the quadrilateral PQRS is 120°

<u>Step-by-step explanation:</u>

Given that

\frac{\angle P}{2} =\frac{\angle Q}{3}=\frac{\angle R}{4}

3P=2Q   (1)

4Q=3R

Q=3R/4

Substitute the value of <Q in (1)

3P=2(\frac{3R}{4} )=\frac{3R}{2} \\6P=3R\          -->(2)

<P=3R/6=R/2

Comparing (1) and (2)

we get 6P=4Q=3R

In a cyclic quadrilateral, opposite angles are supplementary i.e their sum is 180 degree

<P and <R are opposite angles.

Hence

<R/2+<R=180

\frac{3R}{2} =180\\R=120\°\\

<S and <Q are opposite angles. Hence

<S=180-<Q=180-90=90°

<P=60°

<Q=90°

<R=120°

<S=90°

The largest angle of the quadrilateral is 120°(<R)

List the criteria for a binomial experiment. (Select all that apply.)
kolbaska11 [484]

Answer:

The criterion for binomial experiment are:

a. The probability of success on each trial is constant

c. The experiment must include a fixed number of trials repeated under identical conditions

d. The trials are independent.

f. The trials are mutually exclusive

e. The trials have exactly two possible outcomes.

Step-by-step explanation:

The conditions for binomial experiment are that the probability of success remains the same in each trail and the experiment has two outcome success or failure. The trails are mutually exclusive means that the outcome may be success or failure. The trails are repeated fix number of times independently i.e. a trail don't effect the outcome of the other trial.

Use the spinner to answer the question. It is divided into 8 congruent sections. Orange, Blue, Pink, Brown, Purple, Red, Bronze,
valentinak56 [21]

Using proportions, it is found that the statement that Tiffany would expect the spinner to land on a color section beginning with the letter "B" roughly 48 times is True.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, out of 8 sections, 4(Blue, Brown, Bronze and Black) begin with letter "B". We want to find the equivalent amount out of 98 trials. Hence, the <em>rule of three </em>is:

8 trials - 4 start with "B".

96 trials - n start with "B".

Applying cross multiplication:

8n = 4 x 96

n = 0.5 x 96

n = 48.

Hence, the statement is True.

Divide and express the result in standard form. 8/7-i
Gnoma [55]
i=\sqrt{-1}\to i^2=-1\ (i-the\ imaginary\ unit)\\----------------------\\\\\frac{8}{7-i}\\\\use\ (a-b)(a+b)=a^2-b^2\\\\\frac{8}{7-i}\cdot\frac{7+i}{7+i}=\frac{56+8i}{7^2-i^2}=\frac{56+8i}{49-(-1)}=\frac{56+8i}{49+1}=\frac{56+8i}{50}=\frac{56}{50}+\frac{8}{50}i\\\\=\boxed{\frac{28}{25}+\frac{4}{25}i}
