Answer:
The work shown here is correct.
It simplifies to 17x + 36y + 5.
Step-by-step explanation:
In this situation, there are four different items being purchased. This means their will be a sum of 4 terms. Each term will be the number of the item times its cost. When added together, the four terms will represent the total cost.
7 pens at $x is 7x
5 pens at $(2x+3) is 5(2x+3)
y pens at $6 is 6y
(3y-1) pens at $10 each is 10(3y-1)
All together the cost expression is 7x + 5(2x+3) + 6y + 10(3y -1).
Simplify by applying the distributive property and combine like terms.
7x + 10x + 15 + 6y + 30y - 10
17x + 36y + 5
Answer:
- Yes. A p-value of 0.06 indicates that the results observed are not statistically significant at the 5% level, so the 95% confidence interval will include 10.
Step-by-step explanation:
A p-value of 0.06 at 0.05 significance means we fail to reject the null hypothesis that H0: μ = 10 since p-value>p-critical.
This also means that the result is not statistically significant at 0.05 significance level.
Thus, 95% confidence interval for μ includes 10.
75 is the least positive integers which , when subtracted 7300 would make a result a perfect square
<h3>What is the least positive value?</h3>
So normally the least positive integer of all the numbers is the number 1 but when you talk about least positive integer, often times you are talking about the special function called the ceiling function
<h3>Least positive integer:</h3>
The smallest of the numbers in the set {1, 2, 3, …} is 1.
So, the number 1 is the smallest positive integer.
7300
If we Take Square root of 7300 we have to subtract 75 from 7300 to get a perfect square.
7300-75=7225
(85)^2=7225
75 to be subtracted
√7300 ≥ 85
Perfect Square = 85² = 7225 or (7300-7225 = 75)
75 is the least positive integers which , when subtracted 7300 would make a result a perfect square

SA = 2bA (base area) + LA (lateral area)
bA = r^2*pi = 13^2pi = 169pi cm^2
LA = 2r*pi*h = 2*13*pi*88,4 = 2298,4pi cm^2
SA = (2*169pi)+2298,4 pi = 338pi+2298,4pi = 2636,4pi
Answer:
-25 ≠ 21
Step-by-step explanation:
it looks like the question is asking you to solve 5x=4y+9 when given the ordered pair (-5,3)
you would substitute -5 for x and 3 for y in the equation
5(-5) = 4(3) + 9
-25 = 12 + 9
-25 = 21
the question is asking you to see if the left side is equal to the right side of the equation
-25 is not equal to 21, therefore (-5,3) is not a solution to the equation
