Answer:

A. each VIP ticket costs 125$

B. each Regular ticket costs 60$

Step-by-step explanation:

25A+70B=7325

40A+60B=8600

5A+14B=1465

2A+3B=430

10A+28B=2930

10A+15B=2150

13B=2930-2150=780

B=780/13=60

A=（430-3*60）/2=125

Answer:

0.3(least)

0.33

0.35

0.36(greatest)

Step-by-step explanation:

Okay, so first we need to have all of our numbers in the same category of variable. So first, we will convert 9/25 to a decimal.

To do that, we must divide 9 by 25 to get our answer of 0.36.

Now, we will convert the 33% to a decimal by dividing it by 100 to get 0.33

We now have our list, which should be ordered as:

0.3

0.33

0.35

0.36

Answer:

22/25

Step-by-step explanation:

Well, you just convert the 88% into a fraction as probability is in fractions so 88% = 22/25

22/25

Step-by22/25-step explanation:

The prediction for the number of passwords in which the first character is a vowel is 56 passwords.

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

The expected value and variance of X are:

[tex]E(X) = np\\[/tex]

Given that the characters that can be used are numbers 0 through 9 and lowercase letters. Therefore, a total of 36 different characters are available.

Since we need to know the passwords made with vowels, therefore, the probability of a password in which the first character will be a, e, i, o, u is (5/36).

Now as the computer produces 400 passwords, therefore, the predicted value can be written as,

[tex]E = np = 400 \times \dfrac{5}{36} = 55.5556 \approx 56[/tex]

Hence, the prediction for the number of passwords in which the first character is a vowel is 56 passwords.

Answer:

The lateral surface area of a square pyramid is the sum of the areas of the side faces only, whereas the surface area is the lateral area + area of the base. The lateral area of a square pyramid = 2al (or) 2a√[(a 2 /4) + h 2]. To get the surface area, we need to add the area of the base (which is a 2) to each of these formulas.The surface area of a square pyramid = a 2 + 2al (or) a 2 + 2a[(a 2 /4) + h 2]. where, a = Length of the base (square) l = slant height; h = height of the pyramid.

Combine the terms through trigonometric identity and simplify, this should be your answer(not the actual result of the problem, just the simplified expression).

Answer:

Step-by-step explanation:

The rule is generally to reduce anything that isn't a sin(theta) or cos(theta) down to those two.

Givens

Tan(a) = sin(a) / cos(a)

sin(2a) = 2 sin(a)*cos(a)

Solution

Tan(a)/Sin(2a) = sin(a) / cos(a) // 2 sin(a) * cos(a) / 1    Invert and multiply

Tan(a)/Sin(2a) = sin(a) / cos(a) * 2 sin(a) * cos(a)          Cancel and combine

Answer: Tan(a)/sin(2a)  = 1 / (2* cos^2(a))

638.4

Step-by-step explanation:

You could make 2 triangles (One on each side)

91.2*7=638.4

You could cut this in half, but it would be pointless as you are going to add it back again.

Answer:

10 mm

Step-by-step explanation:

We know that the formula for a triangle is A= 1/2(b)(h)

Plug in 30mm for the area as shown and 6 for the base= 30=1/2(6)(h)

Solve= 30=3h

Divide each side by 3 to get h by itself. h=10 or b= 10

depends on which one is missing ^^

Answer:

m∠XWY = 70°

Explanation:

Two opposite interior angle sum up to one exterior angle on a straight line.

============

? + 45° = 115°

? = 115° - 45°

? = 70°

Answer:

The value of angle XWY = 70°

Step-by-step explanation:

=> angle XYZ + angle XYW = 180° { linear pair }

=> angle XYW + 115° = 180°

=> angle XYW = 180° - 115°

=> angle XYW = 65°

Now angle WXY + angle XWY + angle XYW = 180° { sum of angles of a triangle is 180° }

=> 45° + 65° + angle XWY = 180°

=> angle XWY + 110° = 180°

=> angle XWY = 180° - 110°

=> angle XWY = 70°

Answer:

1. (10,-4)

2. 12

3. 108

Step-by-step explanation:

First find the cordinate by seing were the point lands on the graph

sense it is +10 right the x = 10, and it is 4 below the origin making it a negitive 4, so u get (10,-4)

The graph is measured 2 units per box and sence the sides are parallel to the axies you can count each square by 2, giving you the measuers of 12 units.

Now finally, The area of a triangle is A=1/2bh, we arlready have our base, and we just found our hight, so now we just have to plug it in.

A= 1/2 (12) (18)

12*18 = 216

A= 1/2 (216)

A= 108

And we are done!

Answer:

Answer A

Step-by-step explanation:

Approach 1

B, C, and D are wrong because angles 1 and 2 are congruent.

Therefore your answer of both being 60°

Approach 2

Let x = angle 1.

360/x = 6

x = 60°.

Therefore Angle 1 is 60°

An interior angle of a hexagon is 120°

Let y = angle 2.

y is half of 120°

So 120/y = 2

y = 60°
