how to find the mean median and mode for (6, 5 ,6) ( 7 ,6 ) (6 ,7 ) (4 ,6 ) ( 7 ,7 ) ( 6 ,7 ) (7 ,7) ( 4 ,7)
Answer:
the answer is 7
Answer:
7
Step-by-step explanation:
The area of a triangle is 16 units square. The length is twice the height. Find the height
The formula for area of a triangle is 1/2 x base x height.
Let the height = x
Then the base (length) = 2x ( twice the height)
You know have 16 = 1/2 * 2x * x
Multiply both sides by 2 to remove the 1/2:
32 = 2x * x
Simplify the right side:
32 = 2x^2
Divide both sides by 2:
16 = x^2
Take the square root of both sides:
X = 4
The height is 4 units and the length is 8 Units
Paco decides to invest $600 into a bank account that gives him a 3.4% interest rate compounded quarterly. He wants to know how long it will take for him to save up to $1,000.
Answer:
It would take 15 years
Step-by-step explanation:
The length of time it takes to reach $1,000 savings can be determined from the future value formula given below:
FV=PV*(1+r/4)^n*4
FV is the target savings of $1,000
PV is the amount invested which is $600
r is the rate of interest of 3.4%
n is the unknown
1000=600*(1+3.4%/4)^4n
1000=600*(1+0.0085 )^4n
1000=600*(1.0085)^4n
1000/600=1.0085^4n
1.666666667 =1.0085^4n
take log of both sides
ln 1.666666667 =4n ln 1.0085
4n=ln 1.666666667/ln 1.0085
4n=0.510825624 /0.008464078
4n=60.35218768
n=60.35218768 /4
n= 15.09
Un número consta de dos cifras cuya suma es 9.Si se invierten el orden de las cifras el resultado es igual al número dado más 9 unidades. Encuentra dicho número.
Answer:
45
Step-by-step explanation:
A number consists of 2 digits whose sum is 9 => x + y = 9
If the order of the numbers is inverted, the result is equal to the given number plus 9 units => (10*y + x) + 9 = (10*x + y)
Thus:
x + y = 9 => multiply by -9 => 9*y + 9*x = 81
10*y + x + 9 = 10*x + y => 9*y - 9*x = -9
We are left then that:
9*y + 9*x = 81 (1)
9*y - 9*x = -9 (2)
we add both equations
18y = 72
y = 72/18 = 4
replacing
x + y = 9
x + 4 = 9
x = 5
Therefore the number is (10y + x) => (10 * 4 + 5) => 45
Which of the following is the quotient of the rational expressions shown
below?
-1/2y=1/2x+5 and y=2x+2
I assume this is the intersection of two lines, i.e. -1/2y is (-1/2)y. Please tell me if it's really -1/(2y).
(-1/2)y=(1/2)x+5
Multiplying both sides by -2
y = - x - 10
The other equation is
y = 2x + 2
We can equate them to find the meet
y = - x - 10 = 2x + 2
-3x = 12
x = -4
y = 2x + 2 = -6
Check: (-1/2)y=3, (1/2)x+5=3, equal, good
2x+2=2(-4)+2=-6=y, good
Answer: x=-4, y=-6

2)14p+58x
3)33p+19x
4)14p+19x
Answer:
58 x + 33 p thus 1) is the Answer
Step-by-step explanation:
Simplify the following:
11 (3 p + 5 x) + 4 x - x
4 x - x = 3 x:
11 (3 p + 5 x) + 3 x
11 (3 p + 5 x) = 33 p + 55 x:
33 p + 55 x + 3 x
Grouping like terms, 33 p + 55 x + 3 x = (55 x + 3 x) + 33 p:
(55 x + 3 x) + 33 p
55 x + 3 x = 58 x:
Answer: 58 x + 33 p
Answer:

lisa will choose between two restaurants to purchase pizzas for her party. the first restaurant charges a fee of $5 for the entire purchase and $16 per pizza. The second restaurant has no delivery fee and charges $17 per pizza. Please help and hurry
Every time, this second restaurant is less expensive; therefore, Lisa should decide to get pizzas for her group from the second restaurant.
What is the accounting definition of a purchase?All items and services purchased for resale of consumption throughout the production process are included in spending on goods and services, excluding capital goods whose consumption is recorded as consumption for fixed capital.
We have For the first restaurant
the total cost per pizza is $16 + $5 = $21.
For the second restaurant
the total cost per pizza is $17.
If Lisa purchases x pizzas,
the total cost from the first restaurant will be $21x + $5 = $21x + $5.
The total cost from the second restaurant will be $17x.
If x = 1, the first restaurant will cost $26 and the second restaurant will cost $17, so the second restaurant is cheaper.
If x = 2,
the first restaurant will cost $47 and the second restaurant will cost $34, so the second restaurant is cheaper.
If x = 3, the first restaurant will cost $68 and the second restaurant will cost $51, so the second restaurant is cheaper.
So, in every case, the second restaurant is cheaper, and Lisa should choose the second restaurant to purchase pizzas for her party.

A set of middle school student heights are normally distributed with a mean of 150150150 centimeters and a standard deviation of 202020 centimeters. Darnell is a middle school student with a height of 161.4161.4161, point, 4 centimeters. What proportion of student heights are lower than Darnell's height?
Answer:
71.57% of student heights are lower than Darnell's height
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 150, \sigma = 20[/tex]
Darnell has a height of 161.4 centimeters. What proportion of student heights are lower than Darnell's height?
This is the pvalue of Z when X = 161.4.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{161.4 - 150}{20}[/tex]
[tex]Z = 0.57[/tex]
[tex]Z = 0.57[/tex] has a pvalue of 0.7157
71.57% of student heights are lower than Darnell's height
Answer:
0.7157
Step-by-step explanation:
Darnell's height is 161.4 - 150 = \goldD{11.4}161.4−150=11.4161, point, 4, minus, 150, equals, start color #e07d10, 11, point, 4, end color #e07d10 relative to the mean.

What is the slope of the line that passes through the points (-2, 7) and (2,-5)?
Write your answer in simplest form.
Answer:
Denote that line: y = ax + b
Line passes (-2, 7) and (2,-5):
=> -2a + b =7
=> 2a + b = -5
Add both side of above equations:
=> 2b = 2
=> b = 1
=> a = (-5 - 1)/2 = -3
=> Slope a = -3
Hope this helps!
:)
This question is based on the equation of line. Therefore, the slope of the line is -3 that passes through the points (-2, 7) and (2,-5).
Given:
Points are (-2, 7) and (2,-5).
We need to calculate the slope of the line that passes through the points (-2, 7) and (2,-5).
According to the question,
As we know that, equation of line: y = mx +c
It is given that, line passes through points, (-2, 7) and (2,-5).
Now, putting this points in equation of line: y = mx +c.
We get,
=> -2m + c =7 ...(1)
=> 2m + c = -5 ...(2)
Now, adding and solving above two equations,
We get, c = 1
Then, putting the value of b= 1 in equation (1).
We get, m = -3.
Therefore, the slope of the line is -3 that passes through the points (-2, 7) and (2,-5).

5x-2
Step-by-step explanation:
Answer:
y = 5x + 2
Step-by-step explanation:
“the product of a number and five is two less than the number.” numbers unknown so call them x and y, so you have to find the product of x and 5, which is simply 5x, then you know that 5x is two less than y, so you add 2 to balance the equation, which gives you 5x + 2 = y

Lucy and Zachary work at a furniture store. Lucy is paid $200 per week plus 7.5% of her total sales in dollars, x x, which can be represented by g ( x ) = 200 + 0.075 x g(x)=200+0.075x. Zachary is paid $233 per week plus 6% of his total sales in dollars, x x, which can be represented by f ( x ) = 233 + 0.06 x f(x)=233+0.06x. Determine the value of x x, in dollars, that will make their weekly pay the same.
Answer:
[tex] f(x) = g(x)[/tex]
[tex] 200 +0.075 x= 233 +0.06 x[/tex]
We can subtract from both sides 0.06x and we got:
[tex] 0.075 x-0.06x +200 = 233[/tex]
And now we can subtract 200 from both sides we got:
[tex] 0.015 x = 33[/tex]
And dividing both sides by 0.015 we got:
[tex] x = \frac{33}{0.015}= 2200[/tex]
And then the final anwer would be x =2200
Step-by-step explanation:
For this case we have the following function for the total sales of Lucy is given by:
[tex] g(x) = 200 +0.075 x[/tex]
And the function for the total sales of Zachary is given by:
[tex] f(x) =233 +0.06 x[/tex]
And we want to determine the value of x, in dollars, that will make their weekly pay the same, so we can set equal the two functions:
[tex] f(x) = g(x)[/tex]
[tex] 200 +0.075 x= 233 +0.06 x[/tex]
We can subtract from both sides 0.06x and we got:
[tex] 0.075 x-0.06x +200 = 233[/tex]
And now we can subtract 200 from both sides we got:
[tex] 0.015 x = 33[/tex]
And dividing both sides by 0.015 we got:
[tex] x = \frac{33}{0.015}= 2200[/tex]
And then the final anwer would be x =2200
