17. The local hiking club went on a five day huling trip to Denali Nations
Park. The group departed with 60 pounds and returned with no food,
What is the slope of a graph for the amount of food over time (in
pounds per day?
Answer: The slope is 12 pounds per day.
Step-by-step explanation:
They consumed 60 pounds on food in 5 days.
The slope or rate at which they consummed the in a day can be calculated as the amount of pounds consumed in the lapse of time, this is:
slope = 60pounds/5days = 12 pounds per day.

Jenny has saved $600 from her summer job. During the school year, she withdraws $20 from her account every week for her daily expenses. She
wants to keep more than $300 in the account for college. The number of weeks, w, that Jenny can withdraw money from her account is
represented by the inequality 600 – 20w> 300. How many weeks can Jenny continue to withdraw $20 from her account?
A.
14
B.
17
O C.
20
D.
22
Answer:
A
Step-by-step explanation:
since she wants to keep 300 in her account first you would subtract 300 from 600 to get 300. Then you would divide it by 20 to get 15 so your answer would be a because she want's to keep at least 300 in her account.
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]

Answer: =−36x−54
Step-by-step explanation:
=(9)(−4x+−6)
=(9)(−4x)+(9)(−6)
Answer:
-36x - 54
Step-by-step explanation:
Distribute 9 to all terms within the parenthesis. Multiply:

Step-by-step explanation:
Tony rounded 1,143 and 1,149
Answer:
1140 and 1150
Step-by-step explanation:
If your rounding to the tens place.
The rule for rounding is to look at the digit before the one you want to round to.
So if you want to round to the nearest tens, then look at the ones.
If the digit is 0-4 round down. If 5-9 round up.
1143 rounds to 1140 because of the 3
and 1149 rounds to 1150 because of the 9.
Answer:
1200 and 1100
Step-by-step explanation:
Tony rounded each of the numbers 1183 and 1145 to the nearest hundred.
To round the number to nearest hundred , check the digit in tens place.
If the number in tens place is greater than or equal to 5 then we add 1 in hundreds place
If the number in tens place is less than 5 then we replace the remaining digits by 0
In 1183, we have 8 in tens place so 1183 is rounded to 1200
In 1145, we have 4 in tens place so 1145 is rounded to 1100

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

What are the solutions to the equation (x − 21)2 = 25?
Answer:x=7 x=-3
Step-by-step explanation:
(x-2)^2=25
Take the Square root of both sides
(x-2)=±√(25)
x-2=±5
x=2±5
x=2+5 or x=2-5
x=7 or x=-3
The solution for the given equation is x=26 and x=16.
The given equation is (x − 21)² = 25.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The solution for the given equation can be determined as follows:
(x − 21)² = 25
⇒ (x − 21)=±√25
⇒ (x − 21)=±5
⇒ x=±5+21
⇒ x=5+21 and x=-5+21
⇒ x=26 and x=16
Therefore, the solution for the given equation is x=26 and x=16.

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.
Just like Sam said in the question above, '' “Linear regression model is a tool to predict the relationship between the dependent variable, and independent variable...'', that is what linear regression is used for.

= 173873.7
Step-by-step explanation:
For The mean
The mean is going to be sum of the numbers divide by the number
Mean = (130130 +145145+ 215215 +170170+ 165165 +225225+ 240240 +185185+ 130130 +132132 )/10
Mean =1738737/10

Answer:
635
Step-by-step explanation:
Answer:
634.6 cm
Step-by-step explanation:
f^2 = d^2 + e^2 - 2(d)(e)cos(angle)

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
