Answer:
57 ft²
Step-by-step explanation:
Lol I always found the area formula for a parallelogram to be interesting- it's like a rectangle, just the base times the height.
So to find this, you would subtract the area of the parallelogram by the area covered by the car.
(17ft · 9ft) - (16ft ·6ft) = 153ft² - 96ft²
= 57 ft²
Lol don't forget the units! A few of my teachers have been really picky about it, where if you don't include units, the entire answer is wrong : ( but either way, it's a good habit to pick up!
Answer:
With a .95 probability, the margin of error is = 0.392
Step-by-step explanation:
Given -
In order to estimate the average time spent per student on the computer terminals at a local university, data were collected for a sample of 81 business students over a one-week period.
Sample size ( n ) =81
Standard deviation 
= 1.8 hours
= 1 -.95 =.05
= 
= 1.96 (Using Z table)
With a .95 probability, the margin of error is
Margin of error = 
= 
= 
Margin of error = 0.392
The area of steel before cutting:
Area =
cm²
= 
Hence, Area=
Area of steel after cutting out the 11*6 inside dimensions.
As the area should be close to 28 cm square, so equation becomes:
or 
Now for the answer, kindly see the image attached. It gives x=0.76
Hence, the answer is 0.76 cm.
Answer:
The probability is 0.081
Step-by-step explanation:
Here, we want to calculate the probability that the 3rd inspection will be defective.
What this means is that the first two would
not be defective.
Probability of having a defective DVD = 10% = 10/100 = 0.1
Probability of not having a defective DVD = 1 -0.1 = 0.9
So the probability of third being defective = Probability of first not defective * Probability of second not defective * Probability of third defective
= 0.9 * 0.9 * 0.1 = 0.081

▹ Answer
<em>(-2, 1)</em>
▹ Step-by-Step Explanation
4x + 3y = -5
-2x + 2y = 6
4x + 3y = -5
x = -3 + y
4(-3 + y) + 3y = -5
y = 1
x = -3 + 1
x = -2
(x, y) = (-2, 1)
Hope this helps!
