Answer:
C. the life of Supplier B's tires is more predictable than the life of Supplier A's tires.
Step-by-step explanation:
A: The distributions have the same mean, but different standard deviation. They are not the same distribution.
B: The distributions have the same mean, which means on average the tire lifetimes are the same from both suppliers.
C: A smaller standard deviation means values tend to be closer to the mean, hence more predictable. <em>Supplier B's tires have a more predictable life</em>.
D: "Dispersion" is another way to describe the measure provided by standard deviation. Supplier B's tires have a lower tire life dispersion.
As the image is magnified by a factor of 1: 7(1/4)
= 1: (29/4)
= 4/29.
The length of x must've been also increased by a factor of 4/ 29.
Using this,
The scaled value of x will be,
3(4/29)
= 12/29 units.
I'm pretty sure like 80% sure its R'P'Q' if not I'm very sorry
Answer:
D.
Step-by-step explanation:
According to converse of the Pythagorean Theorem, that if the square of the third side (longest side) of a triangle equals the sum of the other two shorter sides, therefore, the triangle formed must be a right triangle.
From the side lengths given, the following satisfies the Pythagorean triple:
5² + 12² = 13².
Therefore, the procedure to use to confirm the converse of the Pythagorean Theorem would be to draw the two shortest side, 5 cm and 12 cm, so that a right angle will be between them. The side measuring 13 cm should therefore fit in to form a right triangle.
The total number of miles is 5.6 so 5.6 miles divided by 3 hours is 1.86recurring miles per hour rounded up to 1.87 miles if you do it to three significant figures.
hope this helps. if any of it doesn't make sense don't hesitate to ask me about it :)
