What is the slope of the line shown in the graph?

Answer:

y = 69

Step-by-step explanation:

start with the distributive property:

5/9 * y and 5/9 * 3

and now you have: 5/9y + 15/9 = 40

and we have to isolate y so subtract 15/9 from both sides:

5/9y + 15/9 = 40

        - 15/9     -15/9

and now you have 5/9y = 345/9

and now divide both sides by 5/9 so: 5/9y divided by 5/9 = y

and 345/9 divided by 5/9 = 345/5 and lets simplify....

y= 69

The calculated price per video game for store A is $1.79 per game

From the question, we have the following parameters that can be used in our computation:

The price per video game for store A is calculated as

Price per video game = Total price/Number of games

using the above as a guide, we have the following:

Price per video game = 8.95/5

Evaluate the quotient

So, we have

Price per video game = 1.79

Hence, the price per video game for store A is $1.79 per game

Answer:

if 8 equal parts then we have 16 parts

O is at zero

16 as at 2

and

29 is away from 2 between 3 and 4

We know this as 16 + 16 is 32 which is 4

count 3/8 between 4 and 3  and when counting 3/8 back we get 29.

Step-by-step explanation:

If 29 meant to be 2/9 then we are still at 2/8 and show the second part 0-1

if 16 was meant to be 1/6 then we know 1/6 is still closer to 1/8 and we show the first divided equal part 1/8

Answer:

\(\frac{87}{20}\)

Step-by-step explanation:

First we need to change the mixed numbers into improper fractions.

9 x 10 = 90 + 1 = 91/10

4 x 4 = 16 + 3 = 19/4

Now we need to get them into simplest terms. There is a few ways to do this, but I know that 10 x 2 = 20 and 4 x 5 = 20 so I will use 20.

\(\frac{91}{10} = \frac{91 x 2}{10 x 2} = \frac{182}{20}\)

\(\frac{19}{4} = \frac{19 x 5}{4 x 5} = \frac{95}{20}\)

Now we can subtract:

\(\frac{182}{20} - \frac{95}{20} = \frac{87}{20}\)

And that leaves us with our answer :D

Step-by-step explanation:

Answer:

the "b" term is the term "-5 x" in the final quadratic expression

Step-by-step explanation:

Normally the "b" is the "linear term" in a quadratic equation.

So, perform the product of binomials and combine like terms to identify the final "b" term of the quadratic expression you get:

\((x-4)*(2x+3)=2x^2 +3x-8x-12=2x^2-5x-12\)

Therefore the "b" term is the term "-5 x" in the final quadratic expression.

Probability of rolling a number greater than 0 but less than 7 is 1.

The probability formula is as follows:

Probability = Favourable outcomes / Total outcomes

Sample space of rolling a dice:

S = {1, 2, 3, 4, 5, 6}

Total outcomes = 6

Favourable outcomes: number greater than 0 but less than 7

Favourable outcomes: 6

Then, probability of rolling a number greater than 0 but less than 7

Probability = Favourable outcomes / Total outcomes

Probability = 6/6

Probability = 1

Thus,  probability of rolling a number greater than 0 but less than 7 is 1.

The complete question is-

A dice is being rolled. Find the probability of rolling a number greater than 0 but less than 7

Answer:

Step-by-step explanation:

The correct answer is a. A larger sample size was used.As per the Law of Large Numbers, the more times an experiment is repeated, the closer the actual results will be to the expected probability. In this case, rolling the cube 100 times provides a larger sample size than rolling it only 20 times. The more rolls that are made, the greater the likelihood that the actual results will converge towards the expected probability of 1/2 for rolling an even number.Option b, The 100 tosses were controlled better, is not relevant to this scenario since the fairness of the cube is assumed.Option c, The expected probability changed when the cube was rolled 100 times, is not true. The expected probability of rolling an even number on a fair six-sided die is always 1/2, regardless of the number of times it is rolled.Option d, The thrower considered only the even rolls, and disregarded the odd rolls, is not a valid assumption. The question states that the number of even rolls was recorded, but it does not imply that odd rolls were disregarded.

Answer:

The  decision rule is  

Reject the null hypothesis  

The conclusion is  

There is sufficient evidence to conclude that the population proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing

Step-by-step explanation:

From the question we are told that

   The sample size is n =  16  

   The population proportion =  0.5

     The number that of students that picked out the teachers dog is k  =  14

Generally the sample proportion is mathematically represented as

       \(\^ p  =\frac{k}{n}\)

=>     \(\^ p  =\frac{14}{16}\)

=>     \(\^ p  = 0.875 \)

The null hypothesis is  \(H_o :  p = 0.5\)

The null hypothesis is  \(H_o :  p >  0.5\)

Generally the test statistics is mathematically represented as

   \(z  =  \frac{\^  p  -  p }{\sqrt{ \frac{p(1- p )}{n} }  }\)

    \(z  =  \frac{0.875   -  0.50 }{\sqrt{ \frac{0.50 (1- 0.50 )}{16} }  }\)

    \(z  = 3\)

Generally the p-value is mathematically represented as

    \(p-value  =  P(Z > 3)\)

From the z table the probability of  Z>3  is mathematically represented as

      \(P(Z > 3) =  0.0013499\)

So

   \(p-value  =  0.0013499 \)

Let  assume the level of significance is  \(\alpha = 0. 05\)

Generally from the value  obtained we see that \(p-value  <  \alpha\) Hence  

The  decision rule is  

Reject the null hypothesis  

The conclusion is  

There is sufficient evidence to conclude that the population proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing

Answer:

45

Step-by-step explanation:

Put in '5' where 'x' is

2 (5)^2 - 5 = 45

What is the equation: \(2x^2-5\)

What do we want to find: f(5)

To find f(5), we must plug the value '5'

     ⇒ into the 'x' position

        ⇒ f(x)

So: \(f(5) = 2(5^2)-5 = 2 * 25 - 5 = 50 -5 = 45\)

Thus f(5) = 45
