- Which fractions are equivalent to 6/8?
Answer:
3/4,
12/16,
18/24,
24/32
30/40
...So on, So on...
Step-by-step explanation:
Any fraction that you multiply by the same number on the bottom and on top.
So, multiply by two, what you do to the top do to the bottom. = 12/16
Multiply by three = 18/24
So on, so on.
Or you can reduce, 6/8 divide by 2 = 3/4.
I'm gonna give you 5 equivalent equations. I also taught you how to do it!

find the slope of the function in the table
Answer:
slope = -6
Step-by-step explanation:
slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
To find the slope, take two points from the table(in this example I'll use points (0,0) and (-2, 12)) and input them into the slope formula:
(0, 0) = (x1, y1)
(-2, 12) = (x2, y2)
[tex]\frac{12-0}{-2-0}[/tex]
Simplify:
12 - 0 = 12
-2 - 0 = -2
[tex]\frac{12}{-2}=-\frac{6}{1}=-6[/tex]
The slope of the function in the table is -6.

When x = 0, y =
When y=0, x=
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)

Determine the slope and the y-intercept of the table.
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.

A sample of 300 urban adult residents of a particular state revealed 65 who favored increasing the highway speed limit from 55 to 65 mph, whereas a sample of 171 rural residents yielded 78 who favored the increase. Does this data indicate that the sentiment for increasing the speed limit is different for the two groups of residents?(a) Test H0: p1 = p2 = 0 versus Ha: p1 = p2 = 0 using a = 0.05, where p1 refers to the urban population. (Round your test statistic to two decimal places and your P-value to four decimal places.)z = P-value = State the conclusion in the problem context.A. Reject H0. The data does not suggest that the sentiment for increasing the speed limit is different for the two groups of residents.B. Fail to reject H0. The data suggests that the sentiment for increasing the speed limit is different for the two groups of residents. C. Fail to reject H0. The data does not suggest that the sentiment for increasing the speed limit is different for the two groups of residents.D. Reject H0. The data suggests that the sentiment for increasing the speed limit is different for the two groups of residents.(b) If the true proportions favoring the increase are actually p1 = 0.24 (urban) and p2 = 0.40 (rural), what is the probability that H0 will be rejected using a level 0.05 test with m = 297, n = 189? (Round your answer to four decimal places.)
Answer and explanation:
Null hypothesis(H0) says sentiment for increasing speed limit in the two populations is the same
Alternative hypothesis(Ha) says sentiment for increasing speed limit in the two populations is different
Where p1 is the first population proportion =65/297= 0.22
And p2 is the second population proportion = 78/189= 0.41
P= p1+p2/n1+n2= 65+78/297+189= 0.29
Hence H0= p1-p2=0
Ha=p1-p2≠0
Test statistic= p1-p2/√p(1-p) (1/n1+1/n2)
= 0.22-0.41/√0.29(1-0.29)(1/297+1/189)
= -4.49
Critical value at 95% significance level= 1.96( from tables)
We therefore reject null hypothesis as critical value is greater than test statistic
Therefore the sentiment for increasing speed limit in the two populations is different
b. at proportions of 0.24 and 0.40 for p1 and p2 respectively
Test statistic = 0.24-0.40/0.29(1-0.29)(1/297+1/189)
= -3.78
P value is 0.0002 at 0.05 significance level
Hence probability =0.4998

What is 7+|−9−2x|=18
Step-by-step explanation:

-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

4t - 3 > 37t - 50
Answer:
4t - 3 > 37t - 50
Step-by-step explanation:
Step 1: 4t - 3 > 37t - 50
-4t -4t
-3 > 33t - 50
+50 + 50
47 > 33t
33 33
t < 47/33
The value for t in the given inequality 4t - 3 > 37t - 50 after solving the inequality is t < [tex]\frac{47}{33}[/tex].
Given an inequality:
4t - 3 > 37t - 50
It is required to find the value of t after solving the inequality.
In order to solve the inequality, write the inequality such that the like terms are on the same side.
Here the like terms in variables are 4t and 37t which are on opposite sides.
The like terms in constant are -3 and -50 which are also on opposite sides.
Consider the inequality:
4t - 3 > 37t - 50
Add 3 on both sides.
4t > 37t - 47
Subtract 37t on both sides.
-33t > -47
Divide both sides by -33. Then the inequality sign also switches to its opposite sign.
t < [tex]\frac{47}{33}[/tex]
Hence the solution of the given inequality is any number t whose value is less than [tex]\frac{47}{33}[/tex].
