Which of the following is the correct point-slope equation for the line that passes through the point (2, -5) and is parallel to the line given by y = -4x + 25?
Answers
Answer:
(-4 - (-2))/(2 - (-2)) = -2/4 = -1/2
Step-by-step explanation:
Pick either point.
y - (-4) = (-1/2)(x - 2)
y + 4 = (-1/2)x + 1
y = (-1/2)x - 3

A horticulturist working for a large plant nursery is conducting experiments on the growth rate of a new shrub. Based on previous research, the horticulturist feels the average weekly growth rate of the new shrub is 3cm per week. A random sample of 45 shrubs has an average growth of 1.50cm per week with a standard deviation of 3cm. Is there overwhelming evidence to support the claim that the growth rate of the new shrub is less than 3cm per week at a 0.050 significance level?
Find the value of the test statistic. Round your answer to three decimal places, if necessary.
Answers
Answer:
Test statistic = - 3.354
We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.
Step-by-step explanation:
H0 : μ = 3
H1 : μ < 3
The test statistic = (xbar - μ) / (s/ √n)
Xbar = 1.50
μ = 3
s = 3
n = 45
Test statistic = (1.5 - 3) / (3/ √45)
Test statistic = - 1.5 / 0.4472135
Test statistic = - 3.354
Pvalue, using the Pvalue from Z score calculator :
Pvalue = 0.00039826
α = 0.05
Pvalue < α ; We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.

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

We know that cosx is adjacent side by hypotenuse.
Cos 37 = Adjacent side/ Hypotenuse
The value of cos37 degrees is 0.7654
0.7654 = x/15

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
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

Since the symbol is facing left on the time line it must face the opposite side which is right.

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)
