find the length of the third side to the nearest tenth
Answers
Answer:
The missing length is 5.3 (a=5.3)
Step-by-step explanation:
The a is the missing side length.
a(2)+6(2)=8(2) The twos will be small and at the right corner of the number/letter.
when there is a 2 at the right corner of a number you will multiply that number with itself.
6×6=36 8×8=64
subtract 36 by 36. subtract 36 by 64(28)
a(2)=28
if you have a scientific caculator there are these buttons you must use at the end. Click the 2nd button, the click the x2 button(close to bottom left)
once you have those buttons clicked add in the number that doesnt have a variable(28)
28=5.29

Determine the slope and the y-intercept of the table.
Answers
To find slope use y2 - y1 / x2 - x1. I would suggest doing this twice just to make sure.
For this one, I will use the first three points. (2,2) (4,5) (6,8)
8 - 5 / 6 - 4 = 3/2
5 - 2 / 4 - 2 = 3/2 = your slope
Now, since there is no (0,y) given, we need to find the y-intercept using . . . You guessed it! Point - slope form! I will use the point (2,2)
y-y₁=m(x-x₁)
y - 2 = 3/2 (x - 2)
y - 2 = 3/2x -3
+2 +2
Y = 3/2x -1
-1 = your y-intercept form.

What is 7+|−9−2x|=18
Answers
Step-by-step explanation:
7+(-9-2x)=18
-9-2x=18-7
-9-2x=11
-2x=11+9
_2x=20
x=20
-2
x= -10
hope u want this..
Answer Step by Step:
Move all terms not containing |-9-2x| to the right side of the equation.
|-9-2x| = 11
Remove the absolute value term. This creates a ± on the right side of the equation because |x| = ±x.
-9-2x=±11
Set up the positive portion of the ± solution.
-9-2x=11
Solve the first equation for x.
x = -10
Set up the negative portion of the ± solution.
-9-2x=-11
Solve the second equation for x.
x = 1
(Answer) x = -10,1

Answer: when x= 0,y= 6
when y= 0,x=3 AND the line type is solid !!
Step-by-step explanation:
The intercepts of the graph are (3, 0) and (0, 6) with the upper part of the graph shaded.
Inequality graphInequality are equations not separated by an equal sign. Given the inequality expression;
-6x - 3y ≤ -18
For the x-intercept: This is the point where the value of y is zero, hence;
-6x - 3(0) = -18
-6x = -18
x = 3
The x-intercept of the function is (3, 0)
For the y-intercept: This is the point where the value of x is zero, hence;
-6(0) - 3y = -18
-3y = -18
y = 6
The y-intercept of the function is (0, 6)

Answer:
A
Step-by-step explanation:
use both points to find the slope using the equation
y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3
then the y int can be any y point, so either -2 or 4. in this case they used 4.
Forty percent of students at a small college have brought their own personal computer to campus. A random sample of 120 entering freshmen was taken.
a. What is the standard error of the sample proportion bringing their own computer to campus.
b. What is the probability that the sample proportions is less than 0.33?
c. What is the probability that the sample proportion is between 0.38 and 0.46?
Answers
Answer: a. Standard Error = 0.045
b. P (p-hat<0.33) = 0.0606
c. P (0.38<p-hat<0.46) = 0.5782
Step-by-step explanation: The sample proportion is p-hat=0.4
a. Standard error of a sample proportion is calculated as:
[tex]SE=\sqrt{\frac{p(1-p)}{n} }[/tex]
with p=0.4 and n=120:
[tex]SE=\sqrt{\frac{0.4(1-0.4)}{120} }[/tex]
[tex]SE=\sqrt{0.002}[/tex]
SE = 0.045
The standard error of the sample proportion of students bringing their own computer is 0.045.
b. To determine the probability for sample proportions, first find the z-score:
P(p-hat < x) = [tex]P(z<\frac{x-\mu}{SE})[/tex]
[tex]P(p-hat<0.33)=P(z<\frac{0.33-0.4}{0.045} )[/tex]
P(p-hat < 0.33) = [tex]P(z<-1.55)[/tex]
Now, using z-score table, find the probability:
[tex]P(z<-1.55)[/tex] = 0.0606
Probability the sample proportion is less than 0.33 is 0.0606.
c. For probability between two proportions, find z-score for each number of the interval:
For p < 0.38:
P(p-hat < 0.38) = [tex]P(z<\frac{0.38-0.4}{0.045} )[/tex]
P(p-hat < 0.38) = [tex]P(z<-0.44)[/tex]
Using z-score table,
[tex]P(z<-0.44)[/tex] = 0.33
For p < 0.46:
P(p-hat < 0.46) = [tex]P(z<\frac{0.46-0.4}{0.045} )[/tex]
P(p-hat < 0.46) = P(z < 1.33)
Probability is
P(z < 1.33) = 0.9082
The probability of the interval is the difference of each probability:
P(0.38 < p-hat < 0.46) = [tex]P(z<1.33)-P(z<-0.44)[/tex]
P(0.38 < p-hat < 0.46) = [tex]0.9082-0.33[/tex]
P(0.38 < p-hat < 0.46) = 0.5782
Probability the sample proportion is between 0.38 and 0.46 is 0.5782.
