The question is an illustration of an equilateral triangle.
From the complete question, the complete side of the triangle contains the following numbers:
1, 6 and 2.
The sum of these numbers represent the side length
[tex]Length = 1 + 6 + 2[/tex]
[tex]Length = 9[/tex]
On the base of the triangle, the numbers are 1 and 3.
So, the number that completes these set of numbers is 5.
This is so because, 5 added to the sum of 1 and 3 is 9
Lastly, the numbers on the last side of the triangle are 2 and 3.
So, the number that completes these set is 4.
This is so because, 4 added to the sum of 2 and 3 is 9

Faced with rising fax costs, a firm issued a guideline that transmissions of 10 pages or more should be sent by 2-day mail instead. Exceptions are allowed, but they want the average to be 10 or below. The firm examined 35 randomly chosen fax transmissions during the next year, yielding a sample mean of 14.44 with a standard deviation of 4.45 pages. (a) At the .01 level of significance, is the true mean greater than 10? (b) Use Excel to find the right-tail p-value.
Answer:
a) The calculated value t = 5.903 > 2.572 at 0.01 level of significance
Null hypothesis is rejected at 0.01 level of significance
There is a true mean value is less than 10
b) p - value 0.00001
The p - value 0.00001 < 0.01
The result is significant at p<0.01
Step-by-step explanation:
Step(i):-
Given mean of the population = 10
Sample size 'n'= 35
Mean of the sample x⁻ = 14.44
Standard deviation of the sample 's' = 4.45
Level of significance ∝ = 0.01
Step(ii):-
Null Hypothesis H₀ : μ >10
Alternative Hypothesis : H₁ : μ < 10
Test statistic
[tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{14.44-10}{\frac{4.45}{\sqrt{35} } }[/tex]
t = 5.903
Degrees of freedom = n-1 = 35-1 = 34
tabulated value t₀.₀₁,₃₄ = 2.572
The calculated value t = 5.903 > 2.572 at 0.01 level of significance
Null hypothesis is rejected at 0.01 level of significance
There is a true mean value is less than 10
p- value :
p - value 0.00001
The p - value 0.00001 < 0.01
The result is significant at p<0.01

Step-by-step explanation:
A county real estate appraiser wants to develop a statistical model to predict the appraised value of houses in a section of the county called East Meadow.One of the many variables thought to be an important predictor of appraised value is the total number of rooms in the house. Consequently the appraiser decided to fit the simple linear regression model, ^y=β0+β1x, where y= the appraised value of the house (in thousands of dollars) and x= the number of rooms. Using data collected for a sample of n = 74 houses in East Meadow, the following results were obtained:¯y=74.80+24.93xRange of the x-values: 5 - 11Range of the y-values: 160 - 300Give a practical interpretation of the estimate of the slope and the y-intercept of the least-squares line.
Answer:
D. For each additional room in the house, the appraised value is estimated to increase $74,800
Step-by-step explanation:
The statistical model is used to predict the appraised value of houses in East Meadows. The value of a house is determined by using variables. The regression model helps to analyse the value of a house. It is predictive modelling technique which determines a relationship between dependent and independent variable.

ABC Bookstore sells new books, n, for $12, and used books, u, for $8. The
store earned $112 revenue last month. The store sold 4 more used books
than new books. Which system of equations represents this scenario?
O A. 8n+ 12u= 112; u= n +4
O B. 8n + 12u=112; U= n- 4
OC. 12n+8u=112; u=n+4
O D. 12n + 8u= 112; u = n-4
Answer:
D.) $12n + $8u = 112 ;u = 4 + n
Step-by-step explanation:
Given that :
Cost per new books (n) = $12
Cost per used book (u) = $8
Total revenue earned = $112
store sold 4 more used books than new books
Hence,
Total revenue should be :
Revenue from new books + Revenue from used book = total revenue
Revenue from new books = $12 * n = $12n
Revenue from used books = $8 * n = $8n
$12n + $8u = 112
Number of books sold :
Number of used books sold = 4 + number of new books sold
u = 4 + n

Answer:
A: g(x)
Step-by-step explanation:
The equation is technically in vertex form "y = a(x – h)² + k", where the vertex is (h, k).
For the domain and range to be as stated in the problem, your "vertex" needs to be (2, 3), and so you want y = a(x – 2)² + 3 which is answer choice A

10 because then the associated lines would be parallel.
15 because then the associated lines would be parallel.
15 because then the associated lines would be coinciding.
10 because then the associated lines would be coinciding.
help plzzz
Answer:
1) 17
2) 15 because then the associated lines would be coinciding
Step-by-step explanation:
1.) 17
2.)
2x - 4y = 10
3x - 6y = r
Step 1
First lets try to substitute r with 10
and that looks like
*Look at the second image*
And it has No Solution because they are parallel
so we can cross out B and C
Step 2
So lets try to substitute r with 15
and that looks like
*Look at the First image*
It might look like there is only one line but there are actually 2 and they are on top of each other
So that means that they are not parallel but they are coinciding
So we can cross A out and that means the answer is D
Step 3
So the answer is 15 because then the associated lines would be coinciding
7/8 times 1/3 times 2/5
Answer:
7/60
Step-by-step explanation:
7/8 times 1/3 is 7/24.
Then, 7/24 times 2/5 is 7/60
When multiplying fractions you just multiply across. For example, 7/8 times 1/3. 7 times 1 is 7 and 8 times 3 is 24. So, 7/8 times 1/3 is 7/24.

45 POINTS--A pattern of shaded and unshaded squares is shown below:
Answer:1) 2n - 1
2) 99
see in the picture, u can see that the number of shaded in figures 1 through n will form an evenly spaced sequence with:
u(1) = 1
u(2) = 3
u(3) = 5
u(4) = 7
u(5) = 9
......
=> The above sequence has: u1 = 1
d = 2
=> u(n) = 1 + 2(n - 1) = 2n - 1
=> the number of shaded squares in the n figure is 2n - 1
b) the number of shaded squares in the 50th figure is 2.50 - 1 = 99
Step-by-step explanation:
a) The number of shaded squares in the n figure is 2n - 1.
b) The number of shaded squares in the 50th figure is 99.
What is the number pattern?A number pattern is a pattern in a series of numbers that represents the common relationship between the numbers.
The number of shaded in figures 1 through n will form an evenly spaced sequence with:
u(1) = 1
u(2) = 3
u(3) = 5
u(4) = 7
u(5) = 9
The above sequence has: u1 = 1, d = 2
u(n) = 1 + 2(n - 1) = 2n - 1

Answer:
y + x > -2
Step-by-step explanation:
slope is negative and is -1
y-intercept is -2
equation of dashed line is y = -x - 2
shading is above the line, and line is dashed, so inequality is
y > -x - 2
Add x to both sides.
y + x > -2

You have $2000 from graduation that you want to invest in your simple interest checking account for five years while you go to college. If the account has a 1.3% interest rate, how much will you have in the account after the five years?
Answer: $2130
Step-by-step explanation:
First, we need to calculate the simple interest which will be:
= (Principal × Rate × Time)/100
= (2000 × 1.3 × 5)/100
= $130
The total amount in the account after five years will be:
= $2000 + $130
= $2130
