Answer:

Yes. Juan will break even because 16 and -16 are a zero pair. -16 is the additive inverse of 16. So the sum will be 0.

Carlos has 4 1/2 gallons of paint. To paint a room that is 10 ft by 10 ft, he uses 34 gallon of paint. How many 10 ft by 10 ft r
Finger [1]

Answer:

C. 6 rooms

Step-by-step explanation:

I think you means he uses 3/4 gallon for 1 room.

This is a division problem. Divide the amount of paint he has by the amount he uses to paint one room.

(4 1/2)/(3/4) = (9/2)/(3/4) = 9/2 * 4/3 = 36/6 = 6

Answer: 6 rooms

3 semicircles are connected to 3 sides of a square. Each side of the square measures 4 centimeters. What is the area of the comp
netineya [11]

the square area is 4x4 is 16

each semicircle has a diameter of 4cm.

area of a semicircle is pi * r^2/2

3.14*2^2/2=6.28

since there are 45 sides of a square, 6.28x3=18.84

add 18.84 and 16.

34.84 is your answer.

Classify the following random variables as discrete or continuous: X: the number of automobile accidents per year in Virginia. Y
Bess [88]

Answer:

X: Discrete random variable

Y: Continuous random variable

M: Continuous random variable

N: Discrete random variable

P: Discrete random variable

Q: Continuous random variable

Step-by-step explanation:

A discrete random variable is a variable that takes countable values such as 0,1,2,3, etc. A continuous random variable is a variable that takes measurable values such as 0.1,1.3,2.6,3.8, etc.

X,N and P are discrete random variables because they have countable values such that Number of automobile accidents,number of eggs laid and number of building permits can be counted as 0,1,2,3, and so on.

Y,M and Q are continuous random variables because they don't have countable values such that the length of time to play,the amount of milk produced and the weight of grain can be measured but can't be counted.

14x^2 + 37x + 5....Richard is designing a new website for students to create study groups and collaborate with other students.
Furkat [3]
Answers:
1) The constant of the polynomial expression represents the:
number of group members when the site launches

2) The binomial (1+7x) is a factor of the polynomial expression and represents the:
number of members per group after x months

Solution:
1) The estimate for the total number of groups members (y) is given by the polynomial expression:
y=14x^2+37x+5
where x is the number of months since the site's launch.

When the site launchs:
x=0→y=14(0)^2+37(0)+5=14(0)+0+5=0+0+5→y=5
The number of group members when the site launches is 5
And the problem says: "The site will launch with five study groups"

2) The site will launch with five study groups, each with its creator as its only member, then the number of members per group is 1.
Richard estimates that seven new members will be added to each study group every month (x), then:
The number of members per group after x months will be: 1+7x
