How do you interpret algebraic expressions in terms of their context

Answers

Algebraic expressions are composed of numbers and variables. To interpret them, you must have the word problem to provide you with some context. The variables signify parameters that are maybe unknown in the problem. Although unknown, they can have relationships with each other. The relationships are expressed in algebraic equations.

From the 11

male and 6

female sales representatives for an insurance company, a team of 3

women will be selected to attend a national conference on insurance fraud.
In how many ways can the team of 5

be selected?

Answers

Selecting r objects out of n objects, can be done in C(n, r) many ways.

For example selecting groups of 4 people out of 10 people can be done in
C(10, 4) many ways.

C(n, r) is calculated as follows: [tex]C(n, r)= \frac{n!}{r!(n-r!)} [/tex],

where n! is 1*2*3*...*(n-1)*n

3 men out of 11 men, and 2 women out of 6 women are to be selected.

This can be done in C(11, 3) and C(6,2) ways respectively.

Since any of the selected men group can be combined with any of the selected women group, there are C(11, 3)*C(6,2) many ways of selecting the team of 5.

[tex]C(11, 3)*C(6,2) = \frac{11!}{8!3!} * \frac{6!}{4!2!}= \frac{11*10*9*8!}{8!*3!}* \frac{6*5*4!}{4!*2!}= \frac{11*10*9}{3*2*1} * \frac{6*5}{2*1}= [/tex]

A school did a survey among 100 students to find their sports preferences. The students were asked about their preferences for football or baseball. Out of the total 77 people who liked football, 48 also liked baseball. There were 65 people who liked baseball. Part A: Summarize the data by writing the values that the letters A to I in the table below represent. (5 points) Like football Do not like football Total Like baseball A D G Do not like baseball B E H Total C F I Part B: What percentage of the survey respondents did not like either football or baseball? (3 points) Part C: Do the survey results reveal a greater dislike for football or baseball? Justify your answer. (2 points)

Answers

PART A:

Total of students who like football = 77 students
Students who like football and baseball = 48 students
Students who like football and not baseball = 77 - 48 = 29 students

Students who do not like football = 100 - 77 = 23 students

Students who like baseball = 65 students
Students who like baseball but not football = 65 - 48 = 17 students

Students who do not like baseball = 100 - 65 = 35 students

These data can be represented in a two ways table as shown below

PART B:

The number of students who do not like either football or baseball is 29+17+6=52

The probability is 52/100 = 52%

PART C:

The number of students who don't like football is 17+6=23 students
The number of students who don't like baseball is 35 students

The survey result reveals a greater dislike for baseball

What is 18a and 12ab's GCF

Answers

Answer:

Step-by-step explanation:

18a = 2 · 3² · a

12ab = 2² · 3 · a · b

Factors common to both lists are 2, 3, a, so the GCF is 2·3·a = 6a.

Consider the following.
Point
(-5, 4)
Line
x + y = 7
(a) Write the slope-intercept form of the equation of the line through the given point and parallel to the given line.

(b) Write the slope-intercept form of the equation of the line through the given point and perpendicular to the given line.

Answers

x + y = 7....y = -x + 7....the slope here is -1

A. a parallel line will have the same slope
y = mx + b
slope(m) = -1
(-5,4)...x = -5 and y = 4
sub and find b, the y int
4 = -1(-5) + b
4 = 5 + b
4 - 5 = b
-1 = b
so ur parallel line is : y = -x - 1 <==

B. perpendicular lines have negative reciprocal slopes. That means our perpendicular line will have a slope of 1
y = mx + b
slope(m) = 1
(-5,4)...x = -5 and y = 4
now we sub and find b, the y int
4 = 1(-5) + b
4 = -5 + b
4 + 5 = b
9 = b
so ur perpendicular line is : y = x + 9 <==

The equation d=13/v shows that the density of a particular substance equals a mass of 13 grams divided by the volume of the substance. What happens to the density as the volume approaches 0?

Answers

d = M/V where M=mass and V = volume

Assume the Mass is 1 kg and the Volume = 1 cm³, so d= 1/1 kg/cm³

for V=0.1 → d = 1/0.1 = 10 kg.cm³
for V = 0.01 → d = 100.kg.cm³
for V = 0.001 → d = 1000.kg.cm³
for V = 0.000001 → d = 1,000,000.kg.cm³
and when Volume → 0. density →∞
.

Answer: the density approaches infinity

The casino la bella fortuna is for sale and you think you might want to buy it, but you wantto know how much money you are going to make. all the present owner can tell you is thatthe roulette game red or black is played about 1000 times a night, 365 days a year. eachtime it is played you have probability 19/37 of winning the player’s bet of $10 and probability18/37 of having to pay the player $10.

Answers

Expected gain per player per game
10*(19/37)-10*(18/37)=0.27027
Expected gain per player per night (1000 games per night)
=1000*0.27027
=270.27
Expected gain per player per year (365 nights per year)
=270.27*365
=98648.65

Revenue is 98648.65 times the average number of players per game.

Final answer:

The expected value of the roulette game red or black is -$0.62 per game, indicating an expected average loss.

Explanation:

The expected value of the roulette game red or black can be calculated by multiplying the probabilities of winning and losing by their corresponding outcomes. In this case, the probability of winning ($10) is 19/37, and the probability of losing ($-10) is 18/37. Multiply these probabilities by their corresponding outcomes and subtract to get the expected value:

Expected value = (19/37 * $10) + (18/37 * -$10) = -$0.54 + (-$0.54) = -$0.62

This means that if you play this game repeatedly, over a long string of games, you would expect to lose an average of 62 cents per game.

A new basketball costs $25.00 at the sporting goods store. If the store is having a going-out-of-business sale and everything is 60% off, what is the actual cost of the basketball?

Answers

Final answer:

To calculate the discounted price of the basketball, multiply the original price ($25.00) by 60% to find the discount ($15.00), and subtract this from the original price to get the final price ($10.00).

Explanation:

To find out the actual cost of the basketball after a 60% discount, we start by calculating the amount of the discount. A 60% discount on a $25.00 basketball means the discount is 60/100 times $25.00. To do the calculation:

First, we convert the percentage to a decimal: 60% = 0.60.Then, we multiply the original price by the decimal: $25.00 × 0.60 = $15.00.This $15.00 is the amount of the discount.

To find the discounted price, we subtract the discount from the original price: $25.00 - $15.00 = $10.00. Therefore, the discounted price of the basketball is $10.00.

You have 45 ft of the fence you enclose your yard, you are going to use the side of your house as one of the sides and put a fence down the width of the yard so your dog as a place to play, the length is three less than the width. What is the area of your yard?

Answers

We have 45 ft of the fence and we are going to use the side of the house as one of the sides ( on length ).
L = W - 3
2 W + L = 45
2 W + W - 3 = 45
3 W = 45 + 3
3 W = 48
W = 48 : 3
W = 16 ft
L = 16 - 3 = 13 ft
A = 16 * 13 = 208 ft²
Answer: The area of the yard is 208 ft².

find the volume of a sphere with a diameter of 25 cm. approximate pi as 3.14 and round your answer to the nearest hundredth

Answers

4/3[tex] \pi [/tex]r^3 is the forumla, and r = d/2, so 25/2 = 12.5 so r = 12.5 cm

4/3*[tex] \pi [/tex]*(12.5)^3 = 4/3*[tex] \pi [/tex]*1953.125 = 4/3 * 6132.8125 =

Branliest Please!

The formula for the volume of a sphere is:

V=4/3πr³

The diameter given is 25 cm, so that means the radius is 12.5 cm.

Now you just need to plug in the numbers and you will have:

V=(4/3)(3.14)(12.5)³

After plugging that all in the calculator, you should get the answer:

V=8,177.083333 cm³, which rounds to 8,177.08 cm³
