Let f (t) be the number of people, in millions, who own cell phones t years after 1990. Explain the meaning of the following statement.
f (10) = 110.3
Answer:
10 years after 1990 (or in the year 2000) there are 110.3 million people who own cell phones.
Step-by-step explanation:
t= 10 years after 1990.
We are given that f(t) is # of people in millions who own cell phones.
f(10) = 110.3 implies in 10 years after 1990, there are 110.3 million people who owned cell phones.
Given that,
Let f (t) be the number of people, in millions, who own cell phones t years after 1990. To explain the meaning of the following statement, f (10) = 110.3
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
f (t) be the number of people, in millions, who own cell phones t years after 1990.
f(10) = 110.3
Implies,
In 10 years after 1990, there are 110.3 million people who owned cell phones.
Thus, f(10) = 110.3 implies in 10 years after 1990, there are 110.3 million people who owned cell phones.

Answer:
Step-by-step explanation:
Givens
C = 2*pi*r
C = pi*d
C = 125.6
r = d/2
Solution
C = pi *d
125.6 = 3.14 * d Divide both sides by 3.14
125.6/3.14 = d
d = 40
You can use 1 of 2 methods to get the radius
The easiest one is use
r = d/2
r = 40/2

Three consecutive integers have a sum of 72. Find the integers.
Answer:
Step-by-step explanation:
x is smallest integer
x + (x + 1) + (x + 2) = 72
3x + 3 = 72
3x = 69
x = 23.
This means that the integers are 23, 24, and 25.

A teacher asked 23 students to close their eyes, then raise their hand up when they thought 60 seconds had elapsed.

I need help ASAP
Answer:
Stem and leaf plot.
Step-by-step explanation:
The stem and leaf plot is the most appropriate way because it has lots of different values, and they can be grouped according to their tens place. Also, a line graph would have too many values in this situation to be feasible.
A circle has a diameter of 10 yd. What is its circumference?
Answer:
The circumference of the circle is 31.4 yd.
Step-by-step explanation:
From the question,
We are to determine the circumference of a circle whose diameter is 10 yd.
The formula for calculating the circumference of a circle in terms of diameter is given as
C = πd
Where C is the circumference
and d is the diameter
From the given information
d = 10 yd
and π = 3.14
Putting the parameters into the formula
We get,
C = 3.14 × 10
∴ C = 31.4 yd
Hence, the circumference of the circle is 31.4 yd.

The perimeter of a rectangle is 72 yards. If we increase the length of the rectangle by 3 yards, what will the perimeter of the new rectangle be?
Plz show the work its for midterm.
Answer:
14.3
Step-by-step explanation:
72 divided by 3 equals 24, so we have 24 feet.
1 yard equals 3 feet.
3 yards equal 9 feet.
24+9= 43.
43 feet equal 14.3
Hope this helps! Sorry if it doesn't :(
Answer:
78 yards
Step-by-step explanation:
the perimeter is the outside of the shape, right? so you find the perimeter by adding all of the sides together.
if a rectangle's length is going up by 3, that means one pair of parallel sides are having 3 yards added to them. so essentially you have to add 3 yards twice

A house worth $350,00 when purchased was worth $335,000 after the first year and $320,000 after the second year. Assume the economy does not pick up and this trend continues.
(is this an arithmetic or geo sequence?)
Write an explicit formula for the sequence.
Answer: Arithmetic Sequence
The nth term formula is [tex]a_n = -15,000n + 365,000[/tex]
Delete the commas if needed.
=======================================================
Explanation:
Subtract each adjacent term like this
term2 - term1 = (335,000) - (350,000) = -15,000term3 - term2 = (320,000) - (335,000) = -15,000Each time we get -15,000 which is the common difference and helps show we have an arithmetic sequence.
The nth term formula can be found following these steps.
[tex]a_n = a + d(n-1)\\\\a_n = 350,000 + (-15,000)(n-1)\\\\a_n = 350,000 - 15,000n + 15,000\\\\a_n = -15,000n + 365,000\\\\[/tex]
If we plugged in n = 1, then we'd get,
[tex]a_n = -15,000n + 365,000\\\\a_1 = -15,000(1) + 365,000\\\\a_1 = -15,000 + 365,000\\\\a_1 = 350,000\\\\[/tex]
Showing the first term is $350,000 which is the initial value of the house.
I'll let you try the other values of n.
Plugging in n = 2 would lead to [tex]a_2 = 335,000[/tex]
Plugging in n = 3 would lead to [tex]a_3 = 320,000[/tex]
The table shows success rates for two computer games sessions. Whose success rate changed the most between session 1 and session 2?
A. Alexis
B. Brent
C. John
D. None of them
Please show explanation I will mark brainliest :)
Answer:
B. Brent
Step-by-step explanation:
Let us turn the Session 2 scores into fractions so we have common units.
(John) 52% -> [tex]\frac{52}{100}[/tex]
(Alexis) 57.5% -> [tex]\frac{575}{1000}[/tex]
(Brent) 39.5% -> [tex]\frac{395}{1000}[/tex]
Now, we can simplify them.
(John I divide by 2) [tex]\frac{52}{100}[/tex] -> [tex]\frac{26}{50}=\frac{13}{25}[/tex]
(Alexis, I divided by 5) [tex]\frac{575}{1000}[/tex] -> [tex]\frac{115}{200} =\frac{23}{40}[/tex]
(Brent, I divided by 5) [tex]\frac{395}{1000}[/tex] -> [tex]\frac{79}{200}[/tex]
Now subtract Session 2 from Session 1 for each and figure out which one is the largest to answer the question.
(John) [tex]\frac{2}{3}[/tex] - [tex]\frac{13}{25}[/tex] = [tex]\frac{11}{75}[/tex] or about 0.146667
(Alexis) [tex]\frac{11}{20}[/tex] - [tex]\frac{23}{40}[/tex] = [tex]\frac{-1}{40}[/tex] or -0.025
(Brent) [tex]\frac{7}{10}[/tex] - [tex]\frac{79}{200}[/tex] = [tex]\frac{61}{200}[/tex] or 0.305
Since the absolute value of 0.305 is greatest, B. Brent has the largest success rate change.

Step-by-step explanation:
A data set is given as follows:
Please give the best fit using the least squares with the following functions
(1) y = ax + b;
(2) y = ax + b;
and draw their respective graphs.
(Probability and Statistics)
Entering the values obtained from the data in the table based on the
given functions of y = a·x + b, and y = a·|x| + b, we have;
(1) y = -0.0614·x + 1.58772
(2) y = 0.3824·x + 0.91168
How can the best fit lines be obtained?The least squares regression formula is presented as follows;
[tex]a = \mathbf{\dfrac{\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right) }{\sum \left(x_i - \bar x\right )^2 }}[/tex]
(1) From the data in the table, and by using MS Excel, we have;
[tex]\overline x[/tex] = -0.2
[tex]\overline y[/tex] = 1.6
[tex]\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right)[/tex] = -1.4
[tex]\sum \left(x_i - \bar x\right )^2[/tex] = 22.8
Which gives;
[tex]a = \dfrac{-1.4}{22.8 } \approx \mathbf{-0.0614}[/tex]
1.6 ≈ b - 0.0614 × (-0.2)
b = 1.6 - 0.0614 × (0.2) = 1.58772
The equation of best fit for the function, y = a·x + b, is therefore;
y = -0.0614·x + 1.58772(2) For the function, y = a·|x| + b, we have;
[tex]\overline x[/tex] = 1.8
[tex]\overline y[/tex] = 1.6
[tex]\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right)[/tex] = 2.6
[tex]\sum \left(x_i - \bar x\right )^2[/tex] = 6.8
Which gives;
[tex]a = \dfrac{2.6}{6.8} \approx \mathbf{0.3824}[/tex]
1.6 ≈ b + 0.3824 × (1.8)
b = 1.6 - 0.3824 × (1.8) = 0.91168
The equation of best fit for the function, y = a·|x| + b, is therefore;
y = 0.3824·x + 0.91168Learn more about the least squares regression line here:
