Answer:

when rolling a die you can end up getting 6 possibilities all together.

the number of even numbers in a die is 3.

therefore in the first throw you have a possibility of getting an even number at 0.5 or 50%.

and in the second throw you have a possibility of getting an even number at 0.5 x 0.5 which is 0.25 or 25%.

Hope this helps.

A box contains orange balls and green balls. The number of green balls is seven more than three times the number of orange balls

OverLord2011 [107]

Answer:

52 green, 15 orange

Step-by-step explanation:

g + o = 67 g = green, o = orange, x = total

g = 3o + 7

use substitution: (3o + 7) + o = 67

solve for o:

4o + 7 = 67

4o = 60

o = 60/4 = 15

solve for g:

g + 15 = 67

g = 52

A group conducted a poll of 2025 likely voters just prior to an election. The results of the survey indicated that candidate A w

Answer:

Check Explanation

Step-by-step explanation:

Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample proportion) ± (Margin of error)

The population proportion can take on any value within the confidence interval obtained.

So, for each candidate, we can calculate the confidence interval for the population proportion of popular votes they would each receive.

For candidate A,

Sample Proportion = 47%

Margin of Error = 2%

Confidence Interval = (47%) ± (2%)

Confidence interval = (45%, 49%)

For candidate B,

Sample Proportion = 46%

Margin of Error = 2%

Confidence Interval = (46%) ± (2%)

Confidence interval = (44%, 48%)

The true proportion of popular votes for the two candidates will lie between

Confidence Interval for candidate A

(45%, 49%)

Confidence Interval for candidate B

(44%, 48%)

So, the true proportion of popular votes for candidate A can take on any value from 45% to 49%, and that for candidate B can take on values from 44% to 48%.

Because, A could have 45% and B have 48% or A could have 47% and B too have 47%.

The clear winner cannot be determined from this confidence interval obtained from the survey, it really is too close to call!

Hope this Helps!!!

Find the value of x (approximately),

tresset_1 [31]

Answer:. If the Area is 177, it should have been given in square centimeters.

If one side is 13 cm, the other side is about 13.6cm.

If one side is 11 cm, the other side should be about 16.1 cm. Even the choice is incorrect!

A/x = w

Step-by-step explanation: to find a side when the Area is given, divide the Area by the length or width given.

Y=-2x+5<br> X | Y<br> ____<br> 5<br> -1<br> 2<br> 0

Y_Kistochka [10]

Answers:

Step-by-step explanation:

Plug in the x into the equation and solve.

<h3>Value 1: X = 5</h3>

Y = -2(5) + 5

Y = -10 + 5

Y = -5

<h3>Value 2: X = -1</h3>

Y = -2(-1) + 5

Y = 2 + 5

Y = 7

<h3>Value 3: X = 2</h3>

Y = -2(2) + 5

Y = -4 + 5

Y = 1

<h3>Value 4: X = 0</h3>

Y = -2(0) + 5

Y = 0 + 5

Y = 5

I'm always happy to help :)
