please help me with this equation
Answers
First we need to find x
9 < 4x - 7
Since the equation is not set up properly we need to switch it from right to left.
7 - 4x > 9
Now we solve
7 - 4x > 9
First we add 7 on both sides
7- will be 7+
-7+7 =0
9 + 7 = 16
Next we divided 4 on both sides
4/4=0 ( I know it should be 1 but that’s how it goes)
16/4= 4
So x=4
Equation
X > 4
this symbol > on a time line always must be open.
Since the symbol is facing left on the time line it must face the opposite side which is right.
So the answer is D

In a children's story, a young girl finds that one bowl of soup is too hot, another is too cold, and a third bowl is just
right. Further study reveals that the temperature of the soup bowl that the young girl declared to be just right was
100°F. A researcher would like to test the hypotheses How=100 versus Hou* 100 where ji = the true mean
temperature of all bowls of soup. A 95% confidence interval based on a random sample of 30 bowls of soup is
(100.9, 102.3). Using this interval, can the researcher reject the null hypothesis?
Yes, the null hypothesis can be rejected at the significance level a = 0.05, because 100 is not contained in the and
95% confidence interval.
Yes, the null hypothesis can be rejected at the significance level a = 0.01, because 100 is not contained in the
95% confidence interval.
No, the null hypothesis cannot be rejected at the significance level a = 0.05, because 100 is not contained in the
95% confidence interval.
No, the null hypothesis cannot be rejected at the significance level a = 0.01, because 100 is not contained in the

Suppose the heights of the members of a population follow a normal distribution. If the mean height of the population is 68 inches and the standard deviation is 4 inches, 68% of the population will have a height within which of the following ranges?
Answers
Answer:
68% of the population will have a height between 64 and 72 inches
Step-by-step explanation:
According to the Empirical Rule, 68% of the population will have a height within the range of 1 standard deviation of the mean. This means that the range of possible heights for 68% of the population is between 68-4(1)=64 inches and 68+4(1)=72 inches

Sometimes, the best way to answer a multiple-choice question is to see which choices are self-consistent.
__
Side lengths and their opposite angle measures in a triangle have the same ordering, least to greatest. It is informative to look at the answer choices with this in mind.
1a. C < A < B; a < c < b . . . . inconsistent
2a. C < A < B; c < a < b.
2b. C < A < B; c < a < b . . . . consistent
3a. B < A < C; c < a < b . . . . inconsistent
4a. B < A < C; a < c < b . . . . inconsistent
Only answer choice 2 is self-consistent. It is the correct one.
how do you divide a square in half by connecting two vertices?
Answers
Answer:
diagonally.
Step-by-step explanation:
the vertices are the corners or angles. square has four angles. if you have to divide it in half by connecting 2 vertices, then you would just need to draw a line from one corner, diagonally to another corner. you have 2 halves that are equilateral triangles. think about a grilled cheese sandwich cut in half. make sense?
Identify the distance between the points (9,7,3) and (5,3,2), and identify the midpoint of the segment for which these are the endpoints. Round to the nearest tenth, if necessary.
Answers
Using it's formula, it is found that the distance between the two points is of 5.7 units. Additionally, the midpoint is (7, 5, 2.5).
What is the distance between two points?Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this problem, the points are (9,7,3) and (5,3,2), hence:
[tex]D = \sqrt{(9 - 5)^2 + (7 - 3)^2 + (3 - 2)^2} = 5.7[/tex]
The distance between the two points is of 5.7 units.
What is the midpoint?The midpoint is the mean of the coordinates, hence:
xM = (9 + 5)/2 = 7.yM = (7 + 3)/2 = 5.zM = (3 + 2)/2 = 2.5.The midpoint is (7, 5, 2.5).

Answers
Answer:
mean = 10.2 minutes
median = 9.5 minutes
Step-by-step explanation:
To find the mean, add up all of the results and then divide by the number of students in the sample. Therefore, the work should look like this: 15+8+7+7+11+13=61 --> 61/6=10.1666667
To find the median, order the results from least to greatest and then notice which number is the middle value. Since there is an even number of students in the sample, you will find that both 8 and 11 are the middle values when you put them all in numerical order (7, 7, 8, 11, 13, 15). Therefore, you must find the average of those two number in order to get the median. (8+11=19 --> 19/2=9.5)

Step 1: Subtract 5x from both sides.
3x + 8 − 5x = 5x − 40 − 5x
−2x +8 = −40
Step 2: Subtract 8 from both sides.
−2x + 8 − 8 = −40 − 8
−2x = −48
Step 3: Divide both sides by -2.
