Step-by-step explanation:

The equation that represents the question is 3x + 12y ≤ 240

total monthly cost, C, of Aliyah's round trip weekday commute, given that she takes the bus x times and Uber y times.

C = 3x + 12y

b. Write an inequality that represents the constraints on Aliyah's budget and the number of times she can take the bus and Uber.

3x + 12y ≤ 240 (total monthly cost must be less than or equal to the monthly budget)

x ≥ 0 (the number of bus rides cannot be negative)

y ≥ 0 (the number of Uber rides cannot be negative)

x and y must be whole numbers (since Aliyah can only take a whole number of rides per month)

Therefore , the solution of the given problem of probability comes out to be a)1/78 ,b)65/624 ,c)1/4 ,d)0 and e)12/13.

The basic goal of any considerations technique is to assess the probability that a statement is accurate or that a specific incident will occur. Chance can be represented by any number range between 0 and 1, where 0 normally indicates a percentage but 1 typically indicates the level of certainty. An illustration of probability displays how probable it is that a specific event will take place.

Here,

a.

P(Bert gets a Jack and Ernie rolls a five) = P(Bert gets a Jack) * P(Ernie rolls a five)

= (4/52) * (1/12)

= 1/78

b.

P(Bert gets a heart and Ernie rolls a number less than six) = P(Bert gets a heart) * P(Ernie rolls a number less than six)

= (13/52) * (5/12)

= 65/624

c.

P(Bert gets a face card and Ernie rolls an even number) = P(Bert gets a face card) * P(Ernie rolls an even number)

= (12/52) * (6/12)

= 1/4

d.

P(Bert gets a red card and Ernie rolls a fifteen) = 0

e.

Ernie rolls a number that is not twelve, and Bert draws a card that is not a Jack:

A regular 52-card deck contains 48 cards that are not Jacks,

so the likelihood that Bert will draw one of those cards is 48/52, or 12/13.

Answer:

$9,435.35

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 4.6/100

r = 0.046 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 7,500.00(1 + 0.046/12)(12)(5)

A = 7,500.00(1 + 0.003833333)(60)

A = $9,435.35

Answer:

Step-by-step explanation:

According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to the mass of the object. The law is often stated as F = ma, where F is the net force acting on an object, m is the mass of the object, and a is the acceleration produced by the force.

In the case of the two workers moving boxes in a warehouse, each worker is applying an equal force to the box. This means that the net force acting on the box is the sum of the forces applied by each worker. Since the forces are equal and in the same direction, the net force is simply the double of the force applied by each worker.

Assuming that the boxes have the same mass, the acceleration of each box would be the same. Therefore, the result of the two workers applying equal force to the box would be that the boxes would move with the same acceleration in the direction of the force applied by the workers.

a. Apples:  Lily needs 10 cups of apples for her fruit bowl.

b. Watermelons: Lily needs 13-3/4 cups of watermelons for her fruit bowl.

c. Grapes: The amount of grapes that Lily has is not given

What is arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a fixed constant number, called the common difference, to the preceding term.

To make her fruit bowl, Lily needs 2½ times the amount of each fruit she currently has.

a. Apples:

2½ × 4 cups = 10 cups

Therefore, Lily needs 10 cups of apples for her fruit bowl.

b. Watermelons:

2½ × 5-½ cups = (2 × 5 + 1/2) × 5/2 cups = 13-3/4 cups

Therefore, Lily needs 13-3/4 cups of watermelons for her fruit bowl.

c. Grapes:

The amount of grapes that Lily has is not given, so we cannot calculate how much she needs for her fruit bowl.

If he wants an average of 84, he needs to get at least 93 points.

Remember that the average value between 3 values A, B, and C is:

(A + B + C)/3

Here we know that the first two scores are 76 and 83 points, let's say that the third score is x, if we want to have an average of 84 or more, then we need to solve:

(76 + 83 + x)/3 = 84

x = 252 - 159

In all these life examples that are listed above, the number 100 is divided by 20 giving 5 as the result. which is said to be:

100/20

= 5.

Therefore, reason behind this is that the number 20, in these life examples, is a representative of a whole value and the number 5 represents the number of parts it is being divided into, so when you multiply 20 by 5, you get 100, which represents the total of these five parts.

Answer:

The probability that a light bulb picked at random will last between 1400 and 1500

P(14 00≤X≤1500) = 0.032

Step-by-step explanation:

Explanation:-

Given that mean of the Population = 1000

Given that the standard deviation of the Population = 250 hours

Let 'X' be the random variable in a normal distribution

Let  X = 1400

\(Z = \frac{X-mean}{S.D} = \frac{1400-1000}{250} = 1.6\)

Let X = 1500

\(Z = \frac{X-mean}{S.D} = \frac{1500-1000}{250} = 2\)

The probability that a light bulb picked at random will last between 1400 and 1500

P(x₁≤ X ≤x₂) = P(Z₁≤ Z ≤z₂)

                   = A( Z₂ ) -A(Z₁)

P(1400≤X≤1500)  = P(1.6≤ Z ≤2)

                            =  A(2 ) -A(1.6)

                           =  0.4772-0.4452

                          = 0.032

Final answer:-

The probability that a light bulb picked at random will last between 1400 and 1500

P(14 00≤X≤1500) = 0.032

The bearing used by the control tower to find the aircraft is N31°E + 79.6° or approximately N110.6°E.

Trigonometric ratios are the ratios of the sides of a right triangle. The sine (sin), cosine (cos), and tangent (tan) are three typical trigonometric ratios.

We may use the principles of bearings and trigonometry to solve this problem.

Let's start by drawing a diagram of the situation below:

Here, A represents the aircraft's original location, and B represents the aircraft's location after it has flown 1 mile to the southeast.

To get the bearing used by the control tower to identify the aircraft, we must first calculate the angle between the initial direction (N31°E) and the ending direction (towards B).

This angle can be calculated using trigonometry as follows:

\(\frac{AB}{AC} = tan(theta)\\tan^{-1}(\frac{AB}{AC} ) = theta\)

where AB is the distance between A and B (one mile), AC is the distance between A and the point where the aircraft makes the 90-degree turn (one-quarter mile), and theta is the desired angle.

AB and AC can be calculated as follows:

\(AB = \sqrt{((1 mile)^{2} + (1 mile)^{2} )} \\AB = \sqrt{2} miles\)

(1/4) mile = AC

Substituting these values into theta's formula yields:

\(\\tan^{-1}(\frac{\sqrt{2} }{\frac{1}{4} } ) = theta\)

evaluate this expression and obtain:

theta ≈ 79.6°

As a result, the bearing used by the control tower to find the aircraft is N31°E + 79.6° or approximately N110.6°E.

Answer:

Vertex of a quadratic function (formula)

Step-by-step explanation:

Answer:

The value of p is 22.

Step-by-step explanation:

To simplify the expression (x¹⁰) (x⁴)³, we can use the power of a power rule, which states that when we raise an exponential expression to another exponent, we multiply the exponents. Therefore, we can write:

(x¹⁰) (x⁴)³ = x^(10) * (x^(4))^3

Simplifying the expression in the parentheses using the power of a power rule, we get:

x^(4*3) = x^12

Substituting this back into the original expression, we get:

(x¹⁰) (x⁴)³ = x^(10) * x^12

Using the product of powers rule, we can add the exponents:

x^(10+12) = x^22

Therefore, the expression (x¹⁰) (x⁴)³ is equivalent to x^22, and the value of p is 22.
