Answer:
30
Step-by-step explanation:
2 out of 30 were defective. The percentage rate is found by dividing 2 by 30 and then multiplying by 100, so that would be:
Percentage Defective Rate = 2/30 * 100 = 6.67%
Now, we have to find the expected defective number of bulbs in a total of 450. So we find 6.67% of those. That would be the decimal (0.0667) multiplied by 450:
0.0667 * 450 = 30
So, out of 450 bulbs, 30 would be expected to be defective
Answer:
I believe the answer is C. 90 degrees
Step-by-step explanation:
First you find the lengths of the two vectors, which are both 
. Then you find the angle given the cos using: cos(∅)=
= 
= 0. Then using ∅=acos(0)=
= 90°
Answer: C ) $0.45 per egg
3 dozen eggs = 36 eggs
Price / Units = Unit Price
$16.20 / 36 = $0.45 per egg
The unit price is the price per unit, in this case the unit is each egg.
Answer:
Option C is correct.
Step-by-step explanation:
The rule of dilation implies that when a figure is dilated by a scale factor of 1/2, the length of the sides of the image can be obtained by multiplying the sides of the original figure/object by 1/2.
For example, if the length of a side of a segment is 6 and is dilated by a scale factor of 1/2. The length of the image segment will be 6/2 or 3/2. i.e. the original length 6 of the segment is multiplied by 1/2 to get the image segment 3/2.
Other important thing to consider is when the scale factor to be multiplied is less than 1, than the image will be smaller, but if the scale factor to be multiplied is greater than 1, than the image will be larger.
Now, coming towards the question and lets dilate the sides of the figure A by a scale factor of 1/2.
- The length of the side 5 in will have its image with length 2.5 in.
i.e. 5/2= 2.5
- The length of the side 2 in will have its image with length 1 in.
i.e. 2/2 = 1
- The length of the side 4 in will have its image with length 2 in.
i.e. 4/2 = 2
- The length of the side 1 in will have its image with length 0.5 in.
i.e. 1/2 = 0.5
Therefore, option C is correct.
1. C
2. A
3. B
4. A
