Susan plans to watch 3 movies each month. Write an equation to represent the total number of movies n that she will watch in m months.
Answer:
3n=m
Step-by-step explanation:
Answer:
3m=n
Step-by-step explanation:
m equals the number of months she watches multiply that by three because three plus three plus three is the same as three times three. and n is the equal because that is our total of movies she is going to watch. so three times the number of months she watched three movies consecutively to equal the total number of movies
f(x)=x^2+12x+35, solve f(x)>0
Step-by-step explanation:
Solve the eq f(x) =0x^2+5x+7x+35=0
x*x+5x+7x+5*7=0
x(x+5)+7(x+5)=0
(x+7)*(x+5)=0
x=-7 or x=-5
Now solve f(x) >0So the function is positive (>0) when
x<-7 and when x>-5
Describe all numbers x that are at a distance of 1/2 from the
number – 4. Express this using absolute value notation.
Answer:
| x + 4 | = 1/2
Step-by-step explanation:
We want the numbers on the number line that are at a distance of 1/2 from "-4".
We can express such via the absolute value as :
| x - (-4) | = 1/2
| x + 4 | = 1/2
if ABC forms a linear pair with CBD, use the Linear Pair Postulate to determine the value of x
The value of x from the figure is 13
The sum of angles on a straight line is 180 degrees.
From the given diagram;
2x + 13x - 15 = 180Simplify
15x - 15 = 180
Add 15 to both sides
15x - 15 + 15 = 180 + 15
15x = 195
x = 195/15
x = 13
Hence the value of x from the figure is 13

A square poster has an area measure of 324x^2 + 540x + 225 square units. Determine the side length of the poster.
[tex]\huge\text{$(18x+15)$ units}[/tex]
Given the area, we need to find the side length. Let's start with the area equation for a square, where [tex]s[/tex] is the side length and [tex]A[/tex] is the area.
[tex]s^2=A[/tex]
Substitute in the known value.
[tex]s^2=324x^2+540x+225[/tex]
Now we need to factor the trinomial. The trinomial given for the area is a perfect square trinomial since [tex]324[/tex] ([tex]18^2[/tex]) and [tex]225[/tex] ([tex]15^2[/tex]) are both perfect squares.
We also know that [tex]a^2+2ab+b^2=(a+b)^2[/tex], which we can use to factor.
[tex]s^2=324x^2+540x+225\\s^2=(18x)^2+2(18x)(15)+15^2\\s^2=(18x+15)^2[/tex]
Now, take the square root of both sides to fully isolate [tex]s[/tex].
[tex]\sqrt{s^2}=\sqrt{(18x+15)^2}[/tex]
Keep in mind that the square root of any value squared is the original value.
[tex]s=\boxed{18x+15}[/tex]

Answer:
rules of signs apply
Step-by-step explanation:
The point-slope form of the equation for a line of slope m through point (h, k) is ...
y -k = m(x -h)
If the point coordinates are positive, their values show up in the equation with a minus sign.
Example:
slope 2, point (3, 4)
y -4 = 2(x -3)
__
If a point coordinate is negative, its value shows up in the equation with a plus sign.
Example:
slope 2, point (-3, 4)
y -4 = 2(x -(-3)) . . . . fill in the given value
y -4 = 2(x +3) . . . . . simplify according to sign rules
__
The slope keeps its sign.
Example:
slope -1/2, point (-3, 4)
y -4 = -1/2(x +3) . . . . we only changed the slope from the previous example

a rectangular sign has a length of 3 and 1/2 ft and width of 1 and 1/8 ft will the area of the sign be greater or less than 3 and 1/2 ft, how do you know? What is the area of the sign?
Answer:
The area is 3.9375 cubic ft, so yes, the area will greater than 3 and 1/2 ft.
Hope this helps:)
Step-by-step explanation:
Length of a rectangular sign :-
[tex] = 3 \frac{1}{2} \: \: m[/tex]
Width of a rectangular sign :-
[tex] = 1 \frac{1}{8} \: \: m[/tex]
We know that :-The formula for finding the area of a rectangle is :-
[tex] =\bold{ length \times breadth}[/tex]
Which means :-The area of the rectangular sign:-
[tex] =3 \frac{1}{2} \times 1 \frac{1}{8} [/tex]
[tex] = \frac{(2 \times 3 )+ 1}{2} \times \frac{(8 \times 1) + 1}{8} [/tex]
[tex] = \frac{6 + 1}{2} \times \frac{8 + 1}{8} [/tex]
[tex] = \frac{7}{2} \times \frac{9}{8} [/tex]
[tex] = \frac{7 \times 9}{2 \times 8} [/tex]
[tex] = \frac{63}{16} [/tex]
[tex] ={3 \frac{15}{6} \: \: }[/tex]
[tex] = 3 \frac{15 \div 3}{6 \div 3} [/tex]
[tex] ={ 3 \frac{5}{2} \: m}[/tex]
Thus, the area of the rectangular sign is:-
[tex] =\bold{ 3 \frac{5}{2} \: m}[/tex]
We can see that :-[tex]\bold{3 \frac{5}{2} \: > 3 \: \frac{1}{2} \: }[/tex]
Which will mean that the area of the rectangular sign is greater than [tex] { 3 \frac{1}{2} \: m}[/tex].
Therefore, the area of the rectangular sign is = [tex] \bold{ 3 \frac{5}{2} \: m}[/tex] and it is greater than [tex] \bold{ 3 \frac{1}{2} \: m}[/tex] .

Step-by-step explanation:
Jonathan, a college business student wants to study how many pages of notes fellow classmates took during a semester for a finance class. Past data reveals that pages of notes for a finance college class has a mean of 95 , with standard deviation 25 pages. He plans to take a random sample of 30 such college students and will calculate the mean pages of notes they take to compare to the known pages of notes students take for a finance college class. For these values, the mean and standard deviation of the sampling distribution of sample means for a sample of size 30 are: μx¯=95 and σx¯=2530√=4.6. What is the probability that the sample mean for a sample of size 30 will be at least 99? You may use a calculator or the portion of the z-table given below.
Using the normal distribution and the central limit theorem, it is found that there is a 0.1913 = 19.13% probability that the sample mean for a sample of size 30 will be at least 99.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].For the population, the mean and the standard deviation are given by, respectively, [tex]\mu = 95[/tex] and [tex]\sigma = 25[/tex].
For a sample of 30, we have that:
[tex]n = 30, s = \frac{25}{\sqrt{30}} = 4.6[/tex]
The probability that the sample mean for a sample of size 30 will be at least 99 is one subtracted by the p-value of Z when X = 99, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{99 - 95}{4.6}[/tex]
[tex]Z = 0.87[/tex]
[tex]Z = 0.87[/tex] has a p-value of 0.8078.
1 - 0.8087 = 0.1913.
0.1913 = 19.13% probability that the sample mean for a sample of size 30 will be at least 99.

Natalie buys a basketball for $25.57 and an air pump for $15.61. How much change will she receive if she pays for both items with a $50 bill?
Answer:
[tex]Change = \$8.82[/tex]
Step-by-step explanation:
Given
[tex]Basketball = \$25.57[/tex]
[tex]Air\ Pump = \$15.61[/tex]
[tex]Amount = \$50[/tex]
Required
Determine the change received
First, we need to calculate the total amount spent
[tex]Total = \$25.57 + \$15.61[/tex]
[tex]Total = \$41.18[/tex]
This implies that Natalie pays a total of $41.18
Next, we calculate the change as thus:
[tex]Change = Amount - Total[/tex]
[tex]Change = \$50 - \$41.18[/tex]
[tex]Change = \$8.82[/tex]
Hence, the change is $8.82
