Answer:
-9
Step-by-step explanation:
Think about the Keep and change rule, since this is negative, the more negative numbers there are the more it will go deeper. -4 - 5 is -9 because just create a number line and place -4 one it, then jump backwards 5 times.

Please just write the equation out.
The fastest a human has ever run is 27 miles per hour. How many miles per minute did the human run?
Answer:
0.45 miles per minute
Step by Step Explanation:
Look at the units: miles per hour is miles/hour
If we multiply
miles hour miles
----- * ------- = ---------
hour minute minute
(27 miles/hour)(1/60 hours/minute) = 27/60
= 9/20 = 0.45 miles per minute

Step-by-step explanation:
the negatives cancel each other out therefore 1.02*4= 4.08
When we Evaluate. [tex]0 / -1 * 0^2 * -4[/tex] the values is 0. To evaluate the expression, follow the order of operations (PEMDAS/BODMAS):
P - Parentheses/Brackets
E - Exponents/Orders
MD - Multiplication and Division (from left to right)
AS - Addition and Subtraction (from left to right)
The expression is: [tex]0 / -1 * 0^2 * -4[/tex]
Step 1: Exponents/Orders
0^2 = 0 (Any number raised to the power of 0 is always 0).
Step 2: Division
0 / -1 = 0 (Any number divided by 0 is undefined, but in this case, it would be 0).
Step 3: Multiplication : 0 * 0 * -4 = 0
So, the final answer is 0.

Topic: Parallel and Perpendicular Lines
Which of the following pairs of lines are perpendicular?
Select all that apply.

B.y = x 8 and y= -x –
C. y = x + 2 and y
-x+3
D.y = 3x + 2 and y = 3x - 2
E.y=3 and x = 4
F. y = x 8 and y = -x + 3
Answer:
Step-by-step explanation:
If slope of two lines are equal, then they are parallel lines.
If product of the slope of two lines is (-1), then they are perpendicular lines.
C) y = x + 2
Slope m1 = 1
y = -x + 3
Slope m2 = -1
m1 * m2 = 1 * (-1) = -1
These are perpendicular lines.
D) y = 3x + 2
Slope = m1 = 3
y = 3x - 2
Slope = m2 = 3
Slopes are equal. So, they are parallel lines.
E)y= 3
This line is parallel to x -axis.
x = 4
This line is parallel to y-axis.
So, both lines are perpendicular to each other.
F) y = x + 8
slope m1 = 1
y = -x + 3
Slope = m2 = -1
M1 * m2 = 1 * (-1) = -1
So, These are perpendicular lines

Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
1/5+1/2²+3/10•5=1/7²+15/100
The resultant of the expression (1/5+1/2)^2+3/10⋅5 in mixed number will be 1 99/100.
What is a number system?The number system is a way to represent or express numbers.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
As per the given expression,
(1/5+1/2)^2+3/10⋅5
⇒ (1/5+1/2)²+ 15/10
Take LCM in the bracket as 10
⇒ [(2 + 5)/10]² + 15/10
⇒ (7/10)² + 15/10
⇒ 49/100 + 15/10
Take LCM as 100
⇒ (49 + 150)/100 = 199/100
⇒ 1 99/100
Hence "The resultant of the expression (1/5+1/2)^2+3/10⋅5 in mixed number will be 1 99/100".

Step-by-step explanation:
Write the equation of the line in fully simplified slope Intercept form.
Answer:
y = -0.83x - 2
Step-by-step explanation:
Slope intercept form is y = mx+b.
M is the slope: In this case the slope (rise/run) is 10/12. However, the slope is decreasing is that would make it negative.
Now we have: y = -0.83x + b
B represents the y-intercept. The y-intercept here is -2. So our final equation is:
y = -0.83x - 2

It currently takes users a mean of 25 minutes to install the most popular computer program made by RodeTech, a software design company. After changes have been made to the program, the company executives want to know if the new mean is now different from 25 minutes so that they can change their advertising accordingly. A simple random sample of 51 new customers are asked to time how long it takes for them to install the software. The sample mean is 26.2 minutes with a variance of 16 minutes. Perform a hypothesis test at the 0.01 level of significance to see if the mean installation time has changed. What kind of problem is this
Testing the hypothesis in this problem which is a two-tailed test, we can conclude that there is not sufficient evidence to conclude that the mean time of installation has changed, since the p-value of the test is 0.0364 > 0.01,
At the null hypothesis, we test if the mean is of 25 minutes, that is:
[tex]H_0: \mu = 25[/tex]
At the alternative hypothesis, we test if the mean has changed, that is, if it is different than 25 minutes.
[tex]H_1: \mu \neq 25[/tex]
We have the standard deviation for the sample, thus, the t-distribution is used. The value of the test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which:
X is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.In this problem:
25 is tested at the null hypothesis, thus [tex]\mu = 25[/tex].Sample mean of 26.2 minutes, thus [tex]X = 26.2[/tex].Sample of 51, thus [tex]n = 51[/tex].Variance of 16, thus [tex]s = \sqrt{16} = 4[/tex].The value of the test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{26.2 - 25}{\frac{4}{\sqrt{51}}}[/tex]
[tex]t = 2.14[/tex]
The p-value of the test is found using a two-tailed test(test if the mean is different of a value), with t = 2.14 and 50 degrees of freedom.Using a t-distribution calculator, this p-value is of 0.0364.Since the p-value of the test is 0.0364 > 0.01, there is not sufficient evidence to conclude that the mean time of installation has changed.

- 45." What is Sara's number?
Answer:

Step-by-step explanation:
Answer:
[tex]27[/tex]
Step-by-step explanation:
Let Sara's number be [tex]x[/tex]. Now, we can build an equation.
We have that [tex]-3(x-12)=-45[/tex]. Aha! Now we have a path to the solution!
We can divide both sides of the equation by [tex]-3[/tex] to get [tex]x-12=15[/tex].
Lastly, we add [tex]12[/tex] to both sides to get [tex]x=27[/tex].
So, Sara's number is [tex]\boxed{27}[/tex].
