The price of television is P15,000 less than the twice the price of old model.If it cost P29,078.00 to buy a new television.What is the price of the old model?
Answer:
P22039
Step-by-step explanation:
Cost of new television = 29078
Let the price of old model television = x
2x - 15000 = 29078
2x = 29078 + 15000
2x = 44078
2x/2 = 44078 /2
x = 22039
Hence, price of old model television is P22039

Answer:
2) 2x + 6
3) 8x - 2
4) 5x - 8
Step-by-step explanation:
The quotient of expression (18x²+15x) divided by 3x is 6x+5.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
A quotient is a quantity produced by the division of two expressions.
Here,
A) (18x²+15x)÷3x
Now, 3x(6x+5)/3x
= 6x+5
B) (16x²+48x)/8x
= 8x(2x+6)8x
= (2x+6)
C) (56x²-14x)/7x
= 7x(8x-2)/7x
= 8x-2
D) (20x²-32x)/4x
= 4x(5x-8)/4x
= 5x-8
Therefore, the quotient of expression (20x²-32x) divided by 4x is 5x-8.

A rectangular prism has a length of 4 inches, a height of 5 inches, and a width of 19 inches. What is its volume, in cubic inches?
Answer:
380 cubic inches
Step-by-step explanation:
The basic formula is length x width x height, so it's pretty simple, you just do 4 x 19 x 5! The order doesn't matter as long as it's just the length worth and height
I, sometimes do length x width, then use the answer for that and multiply it by the height (So that I can break it down)

A sheet of paper has a perimeter of 39 inches. If the width of the paper is 8.5
inches, what is the length of the sheet of paper?
Answer:
length of the sheet of paper is 11 in.
Step-by-step explanation:
Let "a" = short end of paper and let "b" = long end of paper.
Let "p" = perimeter
1st equation: p = 39"
2nd equation: 2a + 2b = p plug in "39" for diameter; result:
2nd equation: 2a + 2b = 39
3rd equation: b = 2a - 6
replace "b" in 2nd equation with "2a - 6" from 3rd equation, result:
2a + 2(2a - 6) = 39 simplified to:
2a + 4a - 12 = 39 simplified to:
6a - 12 = 39 simplified to:
6a = 51 simplified to:
a = 51/6 = 8.5
so, a = short end of paper = 8.5 inches
In 3rd equation (b = 2a - 6), substitute "a" with "8.5"
3rd equation becomes: b = 2(8.5) - 6 simplified to:
b = 17 - 6 = 11
so, b = long end of paper = 11 inches
answer to question is: dimensions of paper are ---
8.5 inches wide by 11 inches long
Answer:
The answer is 11
Step-by-step explanation:
So perimeter is base+ base+length+length. Therefore you take 8.5+8.5 which is 17 and subtract it from 39 to get 22. You take 22 and divide it by 2 which leaves you with 11.
Which of the following is the concept illustrated with the misentered data? A. The procedure for constructing the confidence interval is robust. The larger the sample size, the more resistant the mean. Therefore, the confidence interval is less robust. B. The procedure for constructing the confidence interval is robust. The larger the sample size, the more resistant the mean. Therefore, the confidence interval is more robust. C. The procedure for constructing the confidence interval is not robust. The smaller the sample size, the less resistant the mean. Therefore, the confidence interval is more robust.
Answer: B. The procedure for constructing the confidence interval is robust. The larger the sample size, the more resistant the mean. Therefore, the confidence interval is more robust.
Step-by-step explanation:
Large sized data samples usually have more stability than data with small samples, they yield a mean value which edges closer to the value of the population data. This means that large size data samples will have a mean which is more resistant to change than samples with a lower sample size. The confidence interval gives robustness while constructing a model by giving te leverage for a range of values based in a certain level of confidence upon which a statistical vale can be tested for validity.

A student‘s test score is likely to increase about 20 points for each hour of studying
Step-by-step explanation:
We can see that the indepedent value is hours spent studying and dependent value is test scores.
As the hours of studying get greater, so does the test scores. So it has to be either the second to last or last one.
If you pay attention to the numbers, you’d see that the last one would be the answer.
