Step-by-step explanation:
Use limits to find the area between the curve of y = x and the x-axis for the interval from
x= 1 to x= 3.
Links will be reported.
Answer:
The area between the curves is 4 square units.
Step-by-step explanation:
We want to find the area bounded by:
y = x
x = 0
in the interval x = 1, x = 3
This is simply equal to the integral of the function f(x) = x between x = 1 and x = 3
Written as:
[tex]\int\limits^3_1 {x} \, dx[/tex]
And the integral of x is equal to x^2/2
Then:
[tex]\int\limits^3_1 {x} \, dx = (\frac{3^2}{2} - \frac{1^2}{2}) = (\frac{9}{2} - \frac{1}{2} ) = \frac{8}{2} = 4[/tex]
The area between the curves is 4 square units.

Step-by-step explanation:
A circle fits in a square with sides of 12 inches. What is the approximate area of the shaded region between the square and the circle? (Use 3.14 for Pi and round to the nearest whole number.) A circle inside of a square with side lengths of 12 inches. The circle has a diameter of 12 inches. 31 inches squared 69 inches squared 106 inches squared 125 inches squared
Answer:
31 inches squared
Step-by-step explanation:
Area of shaded part = area of square - area of circle
area of square = length²
12² = 144
Area of a circle = πr²
r = radius = 12/2 = 6
(3.14) x 6² = 113.04
Area of shaded part = 144 - 113.04 = 30.96
rounding off to the nearest whole number gives 31
Answer:
31 squared inches

Which function is the same as the linear
function represented by the table?
x y
-4 -14
-2 -8
0 -2
2 4
4 10
Answer:
y=3x-2
Step-by-step explanation:
We know the equation ends in -2 because when x is zero, y is -2
To find the rest of the equation take any other point and take away the -2 from y
Then divide the y by the x to see how may times larger (or smaller) the y is then the x
(I chose -14)
-12÷-4=3
y=3x
the put the -2 back at the end because otherwise, your -14 would be a -12 and that is not a point on the table
1/5(30+a)>5

There are 8 big fish for every___
small fish.
There are 4 big fish for every___
small fish.
The image is attached any way pls someone i beg u help me.
Answer and Step-by-step explanation:
We have to use the image to help us answer this question.
We see that there are 8 big fish in the tank, and 10 small fish in the tank.
So, for the first part, it would be:
There are 8 big fish for every 10 small fish.
For when there are 4 big fish, we need to divide 10 by 2, since 8 divided by 2 is 4.
10 ÷ 2 = 5
So,
There are 4 big fish for every 5 small fish.
I hope this helps!!

The length of a rectangle is 7 cm longer than its width.
The area of the rectangle is 120 cm².
What is the width of the rectangle?
Enter your answer in the box.
Answer:
length = 15 width = 8
Area 15x8 = 120
Step-by-step explanation:
L = length
W= width
L = W + 7 (width plus7)
Area = W x L
Area =W (W+7)
Do the distribution:
120 = W ² + 7W
Subtract 120 on both sides
W + 7W -120 = 0
Factor it
(W + 15)(W - 8) = 0
W = -15 or W = 8
8 is used for W
L = W + 7
L = 8+7=15
Length = 15
Width =8.
Suppose you randomly select a sample of 16 observations from a population with =11 and =2 You find ⎯⎯⎯=9. The sampling error is _____ -2 2 -1 1
Answer:
- 2
Step-by-step explanation:
Given that :
Population mean, μ = 11
Population standard deviation, σ = 2
Sample mean, xbar = 9
Sample size, n = 16
The sampling error could be explained as the variation or difference which exists in statistical measure of the population and sample as the sample data does not totally or wholly represent the population data. This difference in sample and population mean is called sampling error.
Hence, the sampling error in the above scenario can be obtained thus :
Sampling error = (xbar - μ)
Sampling error = 9 - 11 = - 2

Use the original price and the markup to find the retail price.
Original price: $70; Markup: 15%
Answer:
$80.50
Step-by-step explanation:
To find the retail price:
Find 15% of $70. 0.15 × $70 = $10.50Add the markup price to the original price. $70 + $10.50 = $80.50Final answer - $80.50The expression 3(x-9) is equivalent to
03(x)+9.
3(x)+3(9)
03(x) -9.
03(x) – 3(9)
Answer:
The expression equivalent to 3( x - 9) Is
3(x) - 3(9)
3x-27
The answer is D
3(x)-3(9)= 3x-27
A television newscaster from a 24-hour news station wants to estimate the number of hours per day its viewers watch
programming on this channel
. The neviscaster randomly selects 100 viewers and asks them how many hours per day
they watch this station. The newscaster constructs an 85% confidence interval for the true mean number of hours
viewers watch this station. Which of the following would decrease the margin of error?
Answer:
This isn't the best worded question but from what I understand a larger sample size decreases the margin of error. If he would like a more accurate answer a larger sample size of the viewers will give more accurate answers.
