The total number of items in Hazel's wardrobe is 15 + 10 = 25.
The relative frequency of her T-shirts is 15/25 = 0.6.
Answer: 0.6.
A six-sided number cube is to be rolled 30 times. How many times do you expect to roll on an even number?(1 point) bot
There are three even numbers on a six-sided number cube: 2, 4, and 6. Since half of the numbers are even and half are odd, we can expect to roll an even number about half the time.
Since the cube is being rolled 30 times, we can expect to roll an even number about 15 times.
Answer: 15 times.
To find the relative frequency of Hazel's T-shirts, we need to divide the number of T-shirts by the total number of tops in her wardrobe.
The total number of tops in her wardrobe is the sum of T-shirts and short-sleeve blouses: 15 + 10 = 25.
Now, we can calculate the relative frequency of T-shirts by dividing the number of T-shirts (15) by the total number of tops (25):
Relative frequency of T-shirts = 15/25 = 0.6
Therefore, the relative frequency of Hazel's T-shirts is 0.6 in decimal form.
