One box of pencils has 500 pencils in it. Mike bought a box of pencils that has 3% more pencils in it. How many pencils were in the box that Mike bought?
Answer:
Mike's box of pencils contains 515 pencils.
Step-by-step explanation:
3% of 500 is 15. If we add that onto the original 500, we get 515.
A 90% confidence interval for u using the sample results X = 131.2, s=55 , and n= 50 Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places. Margin of error:? 90 Confidence Interval?
Answer:
131.2 ;
12.8 ;
(118.4, 144)
Step-by-step explanation:
Given :
X = 131.2, s=55 , and n= 50
Point estimate of the mean :
Since, sample size is large (n > 30) ; the sample mean = population mean according to the center limit theorem :
Margin of Error = Zcritical * s / sqrt(n)
Zcritical at 90% = 1.645
Margin of Error : 1.645 * (55 / sqrt(50))
Margin of Error : 1.645 * 7.7781745
Margin of Error = 12.795097
Margin of Error = 12.8
The confidence interval (C.I) :
C.I = x ± margin of error
C. I = 131.2 ± 12.8
(131.2 - 12.8) ; (131.2 + 12.8)
(118.4, 144)
Which equation is equivalent to 5= 95÷x
Answer:
5 = 95 divided by 19
Step-by-step explanation:
5 x 19 = 95 = 95 divided by 19 = 5
1.) Solve the equation.
−2(x + 6) + 19 = 11 − 3x
x =
2.)Solve the equation.
x − 23 = 4(2x + 3) − 7
x =
3.) Solve the equation.
1/0 (x + 131) = −2(2 − x)
x =
number three is 1 over 10 ok
Answer:
1) x = 4
2) x = -4
Step-by-step explanation:
1) -2x - 12 + 18 = 11 - 3x
-2x + 7 = 11 - 3x
x = 4
2) x - 23 = 8x + 12 - 7
-7x - 23 = 5
-7x = 28
x = -4

Suppose that the area of a square lawn is 4x^2 + 16x + 16. What is the length of one side of the lawn?
Answer:
2x+4
Step-by-step explanation:
remember the formula (a+b)^2=a^2+b^2+2ab
in this case, 4x^2 would be a^2, 16 would be b^2, and 16x would be 2ab
so, the variable a would be 2x and the variable b would be 4
so, you can turn 4x^2+16x+16 into (2x+4)^2
and since the area of a square is (one of its sides)^2, or in this case (2x+4)^2, the length of one side of the lawn will be 2x+4
problems where you have to use the (a+b)^2=a^2+b^2+2ab formula to turn trinomials into binomials squared are very common, so make sure to look out for questions like these and be ready to use this formula
A paper company needs to ship paper to a large printing
business. The paper will be shipped in small boxes and large
boxes. The volume of each small box is 7 cubic feet and the
volume of each large box is 20 cubic feet. What would be the
total volume, in cubic feet, of 12 small boxes and 13 large
boxes? What would be the total volume, irf'cubic feet, of x
small boxes and y large boxes?
12 small boxes and 13 large boxes:
2 small boxes and y large boxes:
Answer:
Answer A: 344 cubic feet
Answer B: Unkown
Step-by-step explanation:
As for the first question, all we have to do is multiply the amount of both boxes by their sizes (7x12 + 13x20) and make sure to add them up to get 344.
Unfortunately, I wasn't able to get the second answer because I don't exactly understand. My sincere apologies

Mr. Mann asked his class to form a number pattern using the rules:
Use the number 6 as the first term.
To find the other term, subtract 2 from the previous term, then multiply by 2.
The first two numbers in the pattern are 6 and 8.
What is the fourth number in the pattern?
Answer:
20
Step-by-step explanation:
when you subtract 2 from 6 you get 4. so you multiply 4 into 2 which give the answer 8. when you subtract 2 from 8 you get 6 and then you multiply 6 to 2 which gives the answer 12... next you subtract 2 from 12 which gives the answer 10. so you multiply 10 to 2 Which gives the final answer for you which is 20.

Answer:
20²-(13²-5² )=y²
400-(169-25)=y²
400-144 =y²
256=y²
y=16
Step-by-step explanation:
In the diagram above is a 2 right angle triangles
the length of such diagrams is found using the pythagoras theorem.
in finding the length of the vertical by pythagoras gives..(13²-5²)^-2=12
