To demonstrate probabilities, a mathematics teacher had students draw marbles from a bag which contained 9 yellow marbles and 8

blue marbles. During class, the bag was dropped and 2 yellow marbles and 2 blue marbles were lost. Tell whether the loss of marbles changes the probability of drawing a blue marble from the bag. If so, was the probability increase or decreased? Support your answer by calculating the probability for each situation

Answer:

The loss of marbles did not change the probability.

Step-by-step explanation:

This is because the loss was even you lost 2 marbles from both category which keeps them equal similar to when you set two equations equal to one another and then you subtract 2 from each side the sides are still equal.

The SAT is standardized to be normally distributed with a mean µ = 500 and a standard deviation σ = 100. What percentage of SAT
Aliun [14]

Answer:

34.134%

68.268%

Step-by-step explanation:

Given that:

Mean (m) = 500

Standard deviation (s) = 100

Percentage between 500 and 600

P(500 < x < 600)

P(x < 600) - P(x < 500)

Z = (x - m) / s

P(x < 600)

Z = (600 - 500) /100 = 1

P(x < 500)

Z = (500 - 500) / 500 = 0

P(Z< 1) - P(Z < 0)

0.84134 - 0.5

= 0.34134

= 0.34134 * 100%

= 34.134%

B.) Between 400 and 600

P(x < 400)

Z = (400 - 500) /100 = - 1

P(x < 600)

Z = (600 - 500) / 500 = 1

P(Z< 1 ) - P(Z < - 1)

0.84134 - 0.15866

= 0.68268

= 0.68268 * 100%

= 68.268%

Consider this equation:
alexandr1967 [171]

Answer:

we are given the function –2x – 4 + 5x = 8  and is asked in the problem to solve for the variable x in the function. In this case, we can first group the like terms and put them in their corresponding sides:

-2x + 5x =8+4

Then, do the necessary operations.

3x = 12

x = 4.

The variable x has a value of 4.

AlekseyPX

Answer:

Luis

Step-by-step explanation:

One hour is 60 minutes total, leaving and extra 30 minutes for Ava, which is half of 60. So, in fraction form, she walked 1 1/2 OR 1 2/4 hours, which is less than Luis. He walked about an hour and 45 minutes total, or 105 minutes.
