Answer:

[tex]a = \frac{11}{12}[/tex]

Step-by-step explanation:

[tex]a = \frac{5}{4} - \frac{1}{3}[/tex]

[tex]a = \frac{11}{12}[/tex]

Answer:

[tex] \frac{1}{3} + a = \frac{5}{4} [/tex]

[tex]a = \frac{5}{4} - \frac{1}{3} [/tex]

[tex]a = \frac{15 - 4}{12} [/tex]

[tex]a = \frac{11}{12} [/tex]

Answer:

0.0037 = 0.37% probability that the home team would win 65% or more of its games in a simple random sample of 80 games

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

The home team therefore wins 50% of its games

This means that [tex]p = 0.5[/tex]

Determine the probability that the home team would win 65% or more of its games in a simple random sample of 80 games

Sample of 80 means that [tex]n = 80[/tex] and, by the Central Limit Theorem:

[tex]\mu = p = 0.65[/tex]

[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.5*0.5}{80}} = 0.0559[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 0.65. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.65 - 0.5}{0.0559}[/tex]

[tex]Z = 2.68[/tex]

[tex]Z = 2.68[/tex] has a pvalue of 0.9963

1 - 0.9963 = 0.0037

0.0037 = 0.37% probability that the home team would win 65% or more of its games in a simple random sample of 80 games

Answer: 7/24

Step-by-step explanation:

Answer:

7/24 or about 0.29

Step-by-step explanation:

when multiplying fractions you first have to remember that:

a/b * c/d = a*c / b*d

If you remember that then its not hard to calculate:

7/8 * 1/3 = 7*1 / 8*3 = 7/24

Hope i could help :D

Dont be afraid to ask questions :)

Answer:

1001/1500

Step-by-step explanation:

The easiest method for doing this is to just average the two numbers.

e.g. to find a number x between the two numbers ab and cd

x=12[ab+cd]

=12[adbd+bcbd]

=ad+bc2bd

In this case…

x=(2×5)+(3×4)2×2×5=10+1230=2230=1115

You can easily see where that came from.

23=1015 and 45=1215

and the ‘common denominator’ means you just have to pick a value between 10 and 12 . i.e. 11

But you can also say…

23=100150 and 45=120150

and choose any of 101150,102150,...,119150

or

23=10001500 and 45=12001500

and choose any of 10011500,10021500,...,11991500

Answer:4/5 and 2/3 each have a common bottom of 15 so 4/5 is

12/15 and 2/3 will be 10/15

Step-by-step explanation:So than 12/15 forget the bottom don't subtract the bottom just look at it like [12-10] then you got 2 then you go back to the bottom and put it together so your answer is [2/15]

Answer:

yes

Step-by-step explanation:

I think you mean

"Is the product of 3/6 × 5/4 equal to the product of 3/4 × 5/6?"

If we can turn 3/6 * 5/4 into 3/4 * 5/6 using only legal math steps, then the answer is yes.

3/6 * 5/4 =

Breakup each fraction into a product of fractions.

= 3/1 * 1/6 * 5/1 * 1/4

Use the associative and commutative properties of multiplication to change the order and grouping of the multiplication.

= (3/1 * 1/4) * (5/1 * 1/6)

Do each product in parentheses.

= 3/4 * 5/6

This shows that 3/6 * 5/4 = 3/4 * 5/6

Answer: yes

120 : 80

= 12 : 8

= 6 : 4

= 3 : 2

This is the answer

Answer:

120/10=12

80/10=8

12/4=3

8/4=2

Nothing can further decide, then we have

3:2

Answer:

-3/2

Step-by-step explanation:

Answer:

The slope of the line shown is -3/2.

Step-by-step explanation:

You can find this by using the rise/run method between the two points.

Between the two points, the line falls 3 units down (this is the rise part) and goes 2 units to the right (this is the run part). Since the line falls 3 units down between the two points, this number would be -3, and since it runs to the right by two units, the slope can be identified as -3/2.

Answer:

Option d is the correct answer.

Step-by-step explanation:

tan A = 24/7

Answer:

d.) [tex]\frac{24}{7}[/tex]

Step-by-step explanation:

using the sohcahtoa method, where tan A = [tex]\frac{opposite}{adjacent}[/tex], our opposite side is 24, and our adjacent side is 7. our hypotenuse, the longest side, is 25. therefore, we get: d.) 24/7
