Answer:

Step-by-step explanation

Since we are reflecting across the x axis, all of the y coordinates will remain the same. You find the distance away from the x = 4, double it, and add that value to x. So,

X' is now (8,3)

Y' is now (6,0)

Z' is now (4,2) because its x was 0, and anything * 0 = 0 so it does not move.

. Only 2% of a large population of 100-ohm gold-band resistors have resistances that exceed 105 ohms. a. For samples of size 100

Soloha48 [4]

Using the information given above, the sampling distribution of the sample proportion of 100-ohm gold-band is 2.

Sampling distribution of proportion, P = 2% = 0.02

Sample size, n = 100

The sampling distribution of the sample proportion can be calculated thus:

Distribution of sample proportion = np

Distribution of sample proportion = (100 × 0.02) = 2

Therefore, there is a probability that only 2 of the samples will have resistances exceeding 105 ohms.

Rachel bought some buttons2/4 are yellow 2\8 are red which color button was more bought

Lesechka [4]

Rachel bought a collection of buttons.

2/4 of the buttons are yellow. 2/4 * 8 = 1/2 * 8 = 4 yellow buttons
2/8 of the buttons are red. 2/8 * 8 = 1/4 * 8 = 2 red buttons

Therefore, because we know that 4 of the buttons are yellow and 2 of the buttons are red, and we know that 4 > 2, we know that more yellow buttons were bought.
