Nathan and Steven stacked boxes on a shelf. Nathan lifted 13 boxes and Steven lifted 15 boxes. The boxes that Nathan lifted each weighed 12 lb more than the boxes Steven lifted.
Let s represent the weight of the boxes that Steven lifted.
Which expression represents the total number of pounds Nathan lifted?
A. s + 12
B. 15(s+12)
C. 12(s+13)
D. 13(s+12)
Answer:
we assume the two boys lifted the same amount of weight of boxes. Let s be the weight of the boxes Steven lifted. Hence,
Step-by-step explanation:
13 ( s+12) = 15 s
where s + 12 means that the box lifted by Nathan weighed 12 more than that of Steven.
we solve,
s = 78 pounds
such that Nathan's is 90 pounds.
Lisa's father has a large collection of ties. he has 16 ties and 6 of them are blue. if lisa's father chose a tie at random, what is the probability that the tie would be blue?
If Lisa's father randomly pick a tie among his 16 ties, the probability it will be a blue one is 3/8
Probability is a measure how likely an event will happen. The probability of an event A is defined as the number of event A divided by the number of all possible outcomes. Mathematically,
P(A) = n(A)/n(S)
Where:
n(A) = number of event A
n(S) = number of all possible outcomes or sample space.
In the given problem:
Number of all ties = 16
Number of blue ties = 6
Hence, when a tie is picked up randomly, the probability it will be a blue one is:
P(blue) = (number of blue ties) / (number of all ties)
P(blue) = 6/16 = 3/8

Ryan was offered a job after college earning a salary of $60,000. He will get a raise of $4,000 after each year working for the company. Answer the questions below regarding the relationship between salary and the number of years working at the company.
Whoever answers correctly will get Brainliest!!
Answer:
number of years worked, salary, salary, number of years worked, M(x)=4,000x+60,000, M(9)=96,000, switch your very last answer
Step-by-step explanation:
The dependant veriable depends on whatever the independent variable is.
Ryan was offered a job after college earning a salary of $60,000. He will get a raise of $4,000 after each year working for the company.
In this problem, the dependant variable is the salary, because his salary depends on the number of years he's worked.
If you think about it as if it's really happening, it'll make more sense--the longer you work at a job, the more raises you'll get over time.
To put this into an equation, we have to use slope-intercept form: y=mx+b
y is the same as M(x), m is your dependent variable, x is your independent variable, and b is the amount you start with.
Then we just plug the numbers in:
the dependant variable is 4000, independent is the years (which we don't need yet, so it stays as x) and the amount he will start with is 60000
M(x)=4,000x+60000
for M(9), you just plug 9 into x and solve
M(9)=4,000(9)+60000=96,000
Finally, 9 years after being hired, his salary will be 96000 (dollars? I don't know what answer goes here but what you put doesn't really fit)

What is mean in statistics ?The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means. The mean represents the average or middle value of all the data in a dataset as a single number. One of many measures of central tendency, it is also referred to as the arithmetic average.
The mean is significant because it reveals the location of the dataset's median value. Because it contains data from each observation in a dataset, the mean is also significant.
Explanation:
Let [tex]x1 = 62, x2 = 83, x3=91, x4=88, x5=76[/tex]
Test scores count for 20% of the grade, final grades for 25%, and homework grades for 15% of the grade. Therefore
[tex]w1 = w2= w3 = 0.20\\w4 = 0.25\\w5 = 0.15[/tex]
[tex]= > \frac{12.4 + 16.6 + 18.2 + 22+11.4}{1}[/tex]
Which becomes,
[tex]= 80.6[/tex]
According to weights proportionate to values in the final grade, the weighted mean yields the mean value. The observed values are multiplied by the weights, which are then divided by the total number of weights.

In a survey of 232 professional athletes, it was found that 121 of them owned a convertible, 100 of them owned a giant screen tv, and 93 owned a sporting goods store. 18 owned a convertible and a store, 38 owned a tv and a store, and 54 owned a covertible and a tv. 5 owned all three items. how many athletes did not own any of the three items? how many owned a covertible and a tv, but not a store? how many athletes owned a convertible or a tv? how many athletes owned exactly one type of item in the survey? how many athletes owned at least one type of item in the survey? how many owned a tv or a store, but not a convertible?
In a survey of 232 professional athletes, 23 athletes do not own any of the three items. 49 owns a convertible and a tv, but not a store. 163 athletes owns a convertible or a tv. 109 athletes owns exactly one type of item in the survey. 209 athletes owns at least one type of item in the survey. 55 owns a tv or a store, but not a convertible.
Using Venn diagram, a diagram used to present the relationship between sets in a logical form, we analyze the given information.
athletes who do not own any of the three items = 232 - (121 + 100 + 93) +(54 + 38 + 18) - 5 = 23
athletes who owns a convertible and a tv, but not a store = 54 - 5 = 49
athletes who owns a convertible or a tv = (121 + 93) - (18 + 38 - 5) = 163
athletes who owns exactly one type of item in the survey = (121 - 54 - 18 + 5) + (100 - 38 - 54 + 5) + (93 - 18 - 38 + 5) = 109
athletes who owns at least one type of item in the survey = 121 + 100 + 93 - 54 - 38 - 18 + 5 = 209
athletes who owns a tv or a store, but not a convertible = (100 - 54 -38 + 5) + (93 - 18 - 38 + 5) = 55

Rate of change ?
End behavior?
The rate of change is 1/2.
the end behavior of the function is:
as x → ∞, f(x) → ∞
as x → -∞, f(x) → -∞
What is the rate of change?
Here we have a simple linear function:
y = (1/2)*x + 3
Remember that for a general linear function we have:
y = a*x + b
Where a is the rate of change and b is the y-intercept.
Then comparing our function with the general one, we can see that the rate of change is 1/2.
Now, because the rate of change is positive, we can see that when x tends to infinity the function also tends to infinity.
And when x tends to negative infinity also does f(x).
Then the end behavior of the function is:
as x → ∞, f(x) → ∞
as x → -∞, f(x) → -∞

Find each unit rate. Round answers to hundreds
3) $57 for 6 hours of work
The unit rate is $9.50 per hour
A unit means one of several things. A unit rate means a rate for one thing. We write it as a ratio with the denominator being one.For example, if you run 70 meters in 10 seconds, on average you have run 7 meters in 1 second. Both rates, 70 meters in 10 seconds and 7 meters in 1 second, are ratios, but 7 meters in 1 second are unit rates. The unitary method is a method in which you find the value of one unit and then the value of a required number of units.Suppose you go to the market to buy 6 apples. The trader tells you that he is selling 10 apples for Rs 100. In this case, the number of apples is the unit and the price of the apples is the value.
As the rate for 6 hrs. is $57,
the rate is 57/6=(3×19) / (3×2)
=19/2
=9.50
The unit rate is $9.50 per hour

The initial population of a small town was 2.53 thousand. The population grows at a rate of 2.15% each year. After how many years will the population have doubled?
The number of years that the population has doubled will be 33 years.
What is an exponent?Consider the function:
y = a (1 + r) ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
A little town had a population of 2.53 thousand upon its founding. The population increases by 2.15% annually. Then the equation will be
y = 2.53(1.0215)ˣ
The number of years that the population has doubled will be
2 × 2.53 = 2.53(1.0215)ˣ
2 = (1.0215)ˣ
x ln1.0215 = ln2
x = 32.58 ≈ 33 years
The number of years that the population has doubled will be 33 years.
