Answer:
we can say that the points are reflection of each other over the x-axis.
Option D is correct option.
Step-by-step explanation:
We need to find which of the following statements are true about the points (5,3) and (5,-3) is true.
We are given a point (5,3)
and other point (5,-3)
We know that refection over x-axis states that the value of y-coordinate will be negated while x-coordinate value remain same.
In our case, first point (5,3) the coordinates are: x=5, y=3
The other point (5,-3) the coordinates are: x=5, y=-3
The x-coordinate value remains same while, y-coordinate value is negated (negative)
So, we can say that the points are reflection of each other over the x-axis.
Option D is correct option.
Answer: Option D is the correct option.
Step-by-step explanation:
We need to find which of the following statements are true about points (5,3) and (5,-3) is accurate.
We are given a point (5,3)
and another point (5,-3)
We know that reflection over the x-axis states that the value of the y-coordinate will be negated while the x-coordinate value remains the same.
In our case, for the first point (5,3) the coordinates are x=5, y=3
The other point (5,-3) the coordinates are: x=5, y=-3
The x-coordinate value remains the same while, the y-coordinate value is negated (negative)
So, we can say that the points are reflections of each other over the x-axis.
A puppy named Blue started out at 2 pounds and gained 4 pounds every month. How heavy
was Blue at 8 months old?
Answer:
34 pounds
Step-by-step explanation:
One month, Blue will be 6
Two month, Blue will be 10
Three month, Blue will be 14
Four month, Blue will be 18
Five month, Blue will be 22
Six month, Blue will be 26
Seven month, Blue will be 30
Eight month, Blue will be 34
By adding 4 every month, you will get 34
or
4 x 8 = 32
32 + 2 = 34
Sorry if my reasoning doesn't make sense-
Anyways, hopefully this helped! :D

The amount a basketball coach spends at a sporting goods store depends on the number of basketballs the coach buys. The situation is represented by the function rule a= 13b.
Make a table of values and graph the function rule. Is the graph continuous or discrete? Explain.
Suppose the coach spent $117 before tax. How many basketballs did she buy?
The graph is discrete and the coach can buy 9 basketballs with $117.
What are Continuous and Discrete Functions?Continuous functions are those functions for which the value of function can take any number on a certain interval.
Discrete functions, on the other hand, takes separate and distinct values for the function.
The function here is,
a = 13 b
where a is the amount spending on the store and b is the number of basketball she buys.
(a) The table is shown below:
b : 0 1 2 3 4
a : 0 13 26 39 52
The graph is discrete because the function values are discrete.
(b) If the coach spent $117,
a = 117
b = a / 13
b = 117 / 13
b = 9
Hence the graph of the function is discrete and the coach can buy 9 basketballs with the given amount.

In a stem and leaf plot, the stems are typically increments of ten. Therefore, 5, or 50, is the largest stem. Now, in that row, we have to find the biggest leaf. Luckily for us, in stem and leaf plots, the leaves are organized in a least-to-greatest order. We go down to the end of the row and boom! 4. Put the stem and leaf together and we have 54.
On a number line, the directed line segment from Q to S has endpoints Q at a -8 and S at 12 Point R partitions the direct line segment from Q to S in a 4:1 ratio Which expression correctly uses the formula (m/m+n)(x2 - x1) + x1 to find the location of point R?
Answer:
[tex]R =\frac{4}{4+1}(12 +8) -8[/tex]
Step-by-step explanation:
Given
[tex]QS = (-8,12)[/tex]
[tex]Ratio = 4 : 1[/tex]
Required
Determine the expression that correctly uses [tex]\frac{m}{m+n}(x_2 - x_1) + x_1[/tex]
In [tex]QS = (-8,12)[/tex]
[tex](x_1,x_2) = (-8,12)[/tex]
and
[tex]m:n = 4:1[/tex]
Substitute these values in:
[tex]\frac{m}{m+n}(x_2 - x_1) + x_1[/tex]
[tex]R =\frac{4}{4+1}(12 - (-8)) + (-8)[/tex]
The expression becomes:
[tex]R =\frac{4}{4+1}(12 +8) -8[/tex]
Solving further:
[tex]R = \frac{4}{5}(20)-8[/tex]
[tex]R = \frac{4*20}{5}-8[/tex]
[tex]R = \frac{80}{5}-8[/tex]
[tex]R = 16 - 8[/tex]
[tex]R = 8[/tex]
Hence, R is at 8 on the number line

of your the estimated number of tots per minute increases by 27
The question is incomplete. Here is the complete question.
A cell phone company is interested in the relationship between the number of texts per minute for their customers (y) and customer age. Based on the data collected, the least-squares regression line is [tex]y=3.27+2.14x[/tex], where x is the number of years by which age exceeds 12. Which of the following statements best describes the meaning of the slope of the least-squares regression line?
a. For each increase in age of 1 year, the estimated number of texts per minute increases by 3.27.
b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.
c. For each increase of one text per minute, there is an estimated increase in age of 3.27 years.
d. For each increase of one text per minute, there is an estimated increase in age of 2.14 years.
e. The slope has no meaning because the units of measure for x and y are not the same.
Answer: b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.
Step-by-step explanation: The least-squares regression is a method of fitness, i.e., it fits a data set of number into an equation.
In this case, the relationship between number of texts per minute and customer age is given by a line equation:
[tex]y=3.27+2.14x[/tex]
in which, y represents the number of texts per minute and x is the age.
In a line equation, slope is the measure of steepness, i.e., how inclined the line is.
In the least squares regression line, slope is 2.14 and it means, in each additional year, the number of texts increase by a factor of 2.14, which is the correct alternative.

Step-by-step explanation:
The mayor of a town has proposed a plan for the construction of an adjoining bridge. A political study took a sample of 1300 voters in the town and found that 38% of the residents favored construction. Using the data, a political strategist wants to test the claim that the percentage of residents who favor construction is over 35%. Testing at the 0.05 level, is there enough evidence to support the strategist's claim?
Answer:
We reject H₀, we have enough evidence to support the claim that the porcentage of residents who favor construction is over 35%
Step-by-step explanation:
Sample size n = 1300
Sample proportion p = 38 % = 0,38 then q = 62% q = 0,62
The size of the sample is enough to consider the binomial distribution can approximate to normal distribution
p*n = 1300*0,38 q*n = 1300*0,62
p*n > 10 q*n> 10
Population proportion 35% p₀ = 35 % p₀ = 0,35
Hypothesis Test :
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Ha p > p₀
The hypothesis test is a one-tail test to the right
Significance Level α = 0,05 we go to z-table and find z(c)
z(c) = 1,64
To calculate z(s)
z(s) = ( p - p₀ ) / √ p*q/ n
z(s) = 0,38 - 0,35 / √ ( 0,38 * 0,62) / 1300
z(s) = 0,03 / 0,013
z(s) = 2,307
Comparing z(c) and z(s)
z(s) > z(c) 2,307 > 1,64
z(s) is in the rejection region for H₀, we must reject H₀
We have enough evidence to support the claim

They are alternate interior angles and therefore equal.
Solution
8x - 10 = 3x + 90 Subtract 3x from both sides
8x - 3x - 10 = 90 Combine the left
5x - 10 = 90 Add 10 to both sides
5x = 90 + 10
5x = 100 Divide by 5
x = 20
================
That isn't the answer. You need 3x + 90
<B = 3*20 + 90
<B = 60 + 90
<B = 150

A construction crew is lengthening a road that originally measured 41 miles. The crew is adding one mile to the road each day.
Let L be the length (in miles) after D days of construction.
Write an equation relating L to D. Then use this equation to find the length of the road after 14 days.
Answer:
41 + (D x 1) = L
Step-by-step explanation:
To determine the necessary equation to lengthen a road whose initial measure is 41 miles, knowing that a new mile is built every day, the following equation must be performed:
41 + (D x 1) = L
Thus, if 14 days had passed, the length of the journey would be determined as follows:
41 + (14 x 1) = L
41 + 14 = L
55 = L
Therefore, after 14 days, the road's length will be 55 miles.

This is an exemplary illustration of Leftover portion Hypothesis, here on the off chance that you get befuddled as a result of negative remainder, at that point attempt to compose it in easier term this way,
-5 = 13*(-1) + 8 , here 8 is remainder. Remainder can also be 13+5 = 18 by writing like this,
-5 = 13*1 -18, but again dividing -18 by 13 will yield to value which we got earlier that’s 8.
