Answer:

choosing 1 red marble

; choosing 1 white marble, replacing it, and choosing another white marble

; and choosing 1 white marble

Step-by-step explanation:

There are 2+3+5 = 10 marbles. The probability of choosing 1 blue marble is 2/10 = 1/5; this is not greater than 1/5.

The probability of choosing 1 red marble is 3/10; this is greater than 2/10, which is the same as 1/5.

The probability of choosing 1 red marble is 3/10; not replacing it and choosing a blue marble would then be a probability of 2/9. Together this is a probability of 3/10(2/9) = 6/90 = 3/45; this is smaller than 9/45, which is the same as 1/5.

The probability of choosing 1 white marble is 5/10 = 1/2; replacing it and choosing another white marble would be 1/2. Together this is a probability of 1/2(1/2) = 1/4; this is greater than 4/20, which is the same as 1/5.

The probability of choosing 1 white marble is 5/10 = 1/2. This is greater than 2/10, which is the same as 1/5.

hope this helps

Probably the last two, cause there's so many white marbles and there's three red ones so like, you could probably pull a red so that your chance of getting blue in the last answer is higher

Find the equivalent equation that does not contain fractions 2/3 x 7=1/2

mariarad [96]

Answer:

$4x + 42 = 3$

Step-by-step explanation:

Given:

$\frac{2}{3}x + 7 = \frac{1}{2}$

Required

Equivalent expression without fraction

To do this, we simply multiply through by a common multiple of the denominators in the expression.

The denominators are 2 and 3

$2 = 2,4,6,8,10,..$

$3 = 3,6,9,12..$

So, 6 is the least common multiple.

Multiply both sides by 6

$6 * (\frac{2}{3}x + 7) = \frac{1}{2} * 6$

$6 *\frac{2}{3}x + 6*7 = \frac{1}{2} * 6$

$\frac{12}{3}x + 42 = \frac{6}{2}$

$4x + 42 = 3$

Hence, an equivalent expression.

Jamie wants to build a rectangular fence around a new garden. He can afford at most 70

KonstantinChe [14]

Option B is correct. Yes, (9, 22) is a solution to the inequalities and the measurements will fit in the space.

The formula for calculating the perimeter of the rectangular fence is expressed as:

A = 2(L + W) where:

L is the length

W is the width

If Jamie can afford at most 70feet to build a rectangular fence is expressed as:

2L + 2W ≤ 70

We are to check if the garden measure 9 feet by 22 feet. To do this we are to substitute L = 9 and W = 22 into the formula to check if the result will be less than 70

On substituting:

= 2(9) + 2(22)

= 18 + 44

= 62 feet

Since 63 feet is less than 70 feet, hence we can conclude that Yes, (9, 22) is a solution to the inequalities and the measurements will fit in the space.
