Number line with open circle on 7 and shading to the left.
Number line with open circle on 7 and shading to the right.
Answer:
Number line with open circle on 7 and shading to the left
Step-by-step explanation:
Since 7 is not included in "a number less than 7", the circle at 7 is an open circle.
Numbers less than 7 are to the left of 7 on the number line, so the shading will be in that direction.

The box plot shows the number of home runs hit by 43 players during a baseball season which statement best describes the data
The following statement best describes the data as shown in the box plot-
The spread between the lower quartile and the median is greater than the spread between the upper quartile and the median.
Box PlotA box plot is a standardized way of displaying the distribution of data based on a five-number summary that is minimum, lower quartile, median, upper quartile and maximum.
How to read a box plot diagram?The lower quartile of the box plot is represented by the far left-hand side of the box. Here, it is [tex]9[/tex].
The upper quartile of the box plot is represented by the far right-hand side of the box. Here, it is [tex]19[/tex].
The median of the box plot is represented by the vertical bar of the box. Here, it is [tex]15[/tex].
The spread on the box plot is represented by the horizontal distance.
So, spread between the lower quartile and median [tex]=(15-9)=6[/tex]
Spread between the upper quartile and median [tex]=19-15=4[/tex]
[tex]6[/tex] is greater than [tex]4[/tex]
Hence, the spread between the lower quartile and the median is greater than the spread between the upper quartile and the median as shown in the box plot.

In his statistics class, Sam said, “Linear regression model is a tool to predict the relationship between the dependent variable, and independent variable. So, there will be one specific linear regression model that I can use to know the relationship of variables. I decided to use ordinary least square to have the best estimates for linear regression model parameters because ordinary lease square makes me find the linear regression equation with minimum average of difference between actual dependent variable and the value predicted by linear regression model.” Is Sam correct? If not, how do we need to fix his idea?
Answer:
Yes, Sam is correct and there is no need to fix his idea.
Step-by-step explanation:
Linear Regression model is one of the Important model that is been used in statistics especially in statistics which actively involved data analysis of dependent variable and an independent variable. Between these two that is dependent variable and an independent variable, the application of Linear Regression model is used in showing the relationships between the two variables.

16. The local hiking club went on a 7-day hiking trip to Denali National
Park. The group started with 98 pounds and returned with no food.
If the decreasing amount of food each day is modeled by a linear
function, what is the slope of the line?
Answer:
The slope of the line is 14 pounds per day
Step-by-step explanation:
We are given that The local hiking club went on a 7-day hiking trip to Denali National Park.
The group started with 98 pounds
We are also given that the decreasing amount of food each day is modeled by a linear function
On Day 1 amount of food = 98 pounds
Since day 7 was the last day
So, On Day 8 amount of food = 0
So,[tex](x_1,y_1)=(1,98)[/tex]
[tex](x_2,y_2)=(8,0)[/tex]
Slope = Constant Rate of change per unit
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{0-98}{8-1}[/tex]
So, Slope =[tex]\frac{-98}{7}[/tex]
Slope = - 14
Negative sign shows decreasing amount of food each day
Hence the slope of the line is 14 pounds per day

In a certain Algebra 2 class of 25 students, 5 of them play basketball and 10 of them play baseball. There are 12 students who play neither sport. What is the probability that a student chosen randomly from the class plays both basketball and baseball?
Answer:
Probability of students who plays both baseball and basketball is [tex]\frac{2}{25}[/tex]
Step-by-step explanation:
We have given total number of students = 25
5 of them play basket ball 10 of them plays base ball
there are 12 students who neither play baseball nor basket ball
So the number of students who play either baseball or basketball is
[tex]n(A\cup B)=25-12=13[/tex], here A is for basketball and B is for baseball.
From set theory we know that
[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]
[tex]13=5+10-n(A\cap B)[/tex]
[tex]n(A\cap B)=2[/tex]
Therefore there are two students who play both baseball and basketball
Probability is equal to [tex]=\frac{2}{25}[/tex]

Find z1z2 if z1 = 3(cos37° + isin37°) and z2 = 2/3(cos53° + isin53°).
Answer:
[tex]z_{1}\cdot z_{2} = 2\cdot (\cos 90^{\circ} + i \cdot \sin 90^{\circ})[/tex]
Step-by-step explanation:
Both variable can be rewritten into polar form:
[tex]z_{1} = 3\cdot e^{i\cdot 0.205\pi}[/tex] and [tex]z_{2} = \frac{2}{3}\cdot e^{i\cdot 0.294\pi}[/tex]
The complex product is equal to:
[tex]z_{1}\cdot z_{2} = (3)\cdot \left(\frac{2}{3}) \cdot e^{i\cdot (0.205\pi+0.294\pi)}[/tex]
[tex]z_{1}\cdot z_{2} = 2 \cdot e^{i\cdot 0.499\pi}}[/tex]
The resultant expression in rectangular form is:
[tex]z_{1}\cdot z_{2} = 2\cdot (\cos 90^{\circ} + i \cdot \sin 90^{\circ})[/tex]
Answer:
The correct question is:
Find [tex]z_{1}.z_{2}[/tex] if [tex]z_{1}= 3(cos37 + isin37)[/tex] and [tex]z_{2}= \frac{2}{3} (cos53 + isin53)[/tex].
(Note: the angles mentioned in the equations above are in degrees)
The answer is [tex]z_{1}.z_{2}= 2i[/tex]
Step-by-step explanation:
[tex]z_{1}.z_{2}= 3(cos37 + isin37)* \frac{2}{3} (cos53 + isin53)[/tex]
[tex]z_{1}.z_{2}= (3cos37 + 3isin37)* (\frac{2}{3} cos53 + \frac{2}{3}isin53)[/tex]
[tex]z_{1}.z_{2}= 3cos37*\frac{2}{3} cos53 + 3cos37*\frac{2}{3}isin53+3isin37*\frac{2}{3} cos53+3isin37*\frac{2}{3}isin53[/tex]
[tex]z_{1}.z_{2}= 0.961+1.275i+0.724i-0.961[/tex] (Because [tex]i*i=i^{2}=-1[/tex] & [tex]i=\sqrt{-1}[/tex])
[tex]z_{1}.z_{2}= 0.961+1.275i+0.724i-0.961[/tex]
[tex]z_{1}.z_{2}= 2i[/tex]

Find the value of x 6x-10 6x+10
Answer:
total there are 3 values of x as +5/3, -5/3 and 0
Step-by-step explanation:
the given equation is
x(6x-10) (6x+10)=0
this equation can be solved as following
=0 using the formula (a+b)*(a-b)= (a^2-b^2)
here a=6x and b=10
from here we can write either x=0 or 36x^2= 100
or x^2= 100/36 and x=0
or x= ±10/6 and x=0
therefore, total there are 3 values of x as +5/3, -5/3 and 0

We would apply the formula for determining present annuity. It is expressed as
PV = R[1 - (1 + r)^- n]r
Where
PV represents the present value of the investment.
R represents the regular payments made(could be weekly, monthly)
r = represents interest rate/number of interval payments.
n represents the total number of payments made.
From the information given,
r = 1.5/100 = 0.015
n = 30 years
R = $32,635.15
Therefore,
PV = 32635.15[1 - (1 + 0.015)^- 30]/0.015
PV = 32635.15[1 - (1.015)^- 30]/0.015
PV = 32635.15[1 - 0.64]/0.015
PV = 32635.15[0.36]/0.015
PV = 32635.15 × 24
PV = $783243.6

Answer:
it is
Step-by-step explanation:
First differences are ...
29 -33 = -425 -29 = -421 -25 = -4First differences are all the same, so we say the terms have a "common" difference. That is characteristic of an arithmetic sequence.
Yes, this sequence is arithmetic.
Answer:
Yes, in all cases the new term is 4 less than the previous term, and so this sequence is arithmetic.
Step-by-step explanation:
If arithmetic, this sequence must have one and only one difference between terms.
33 - 4 = 29
29 - 4 = 25
25 - 4 = 21
Yes, in all cases the new term is 4 less than the previous term, and so this sequence is arithmetic.
