It is estimated that 65.5% of the students at Foster Middle School will attend the benchmark reward party. Which number is NOT equivalent to 65.5%

Answer:

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Expected number of outcome/Total outcome

Since a pair of die with six faces is rolled, the total number of outcome will be 6^2 = 36

Expected outcome is the sum of dice greater than 10. The only time we can get a sum of the dice grater than 10 is when the following are rolled; (5,6), (6, 5) and (6, 6). The sum of the numbers will give us 11 ans 12 respectively which are values greater than 10.

The expected outcomes = 3 outcomes

The probability that the sum of my dice is greater than 10 = 3/36

Hence the probability that the sum of my dice is greater than 10 is 1/12

Answer:

50%

Step-by-step explanation:

If there's only either a gray piece or a white piece on the spinner and you spun it once, the probability of it landing on gray or white is 50%. But if there are more pieces the answer will be incorrect.

Answer:

Elaine spent $50, Danetta spent $75, and Jan spent $40

Step-by-step explanation:

Let x represent how much Elaine spent:

Danetta will be represented by x + 25

Jan will be represented by x - 10

Then, create an equation:

x + x + 25 + x - 10 = 165

Add like terms and solve for x:

3x + 15 = 165

3x = 150

x = 50

So, this means Elaine spent $50

Plug in 50 as x to find how much Danetta and Jan spent:

x + 25

50 + 25

= $75 (Danetta)

x - 10

50 - 10

= $40 (Jan)

So, Elaine spent $50, Danetta spent $75, and Jan spent $40

The money spent by Danetta is $75, the money spent by Elaine is $50, and the money spent by Jan is $40.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Let D be the money spent by Danetta, E be the money spent by Elaine, and J be the money spent by Jan.

Three friends went shopping. Danetta spent $25 more than Elaine spent. Then the equation will be

D = E + 25

E = D – 25

But Jan spent $35 less than Danetta spent. Then the equation will be

J = D – 35

If they spent $165 in all. Then the equation will be

D + E + J = 165

Put the value of E and J in the above equation.

D + D – 25 + D – 35 = 165

                   3D – 60 = 165

                            3D = 225

                              D = 225 / 3

                              D = 75

Then the value of E will be

E = D – 25

E = 75 – 25

E = 50

Then the value of J will be

J = D – 35

J = 75 – 35

J = 40

Number of product sold (in thousands of $) (y) :

Using the pearson Coefficient of correlation calculator, the correlation Coefficient obtained for the data above is : 0.7077 = 0.708 (3 decimal places).

This depicts a strong positive correlation between the cost of advertising and the number of product sold as the correlation Coefficient is both positive and close to 1. This means payibg a high cost for advert will almost usually result in a corresponding increase in the number of products sold.

Answer:

B. 95

Step-by-step explanation:

Plug in 8625 into the equation as c:

c = 75n + 1500

8625 = 75n + 1500

Solve for n:

7125 = 75n

95 = n

So, 95 people attended.

Answer:

B

Step-by-step explanation:

So we have the equation:

[tex]c=75n+1500[/tex]

Where c represents the wedding cost and n represents the number of people who attended the wedding.

We know that the wedding cost a total of $8625. Thus, we can plug this number in for c and solve for n:

[tex]8625=75n+1500[/tex]

Subtract 1500 from both sides. The right cancels:

[tex](8625)-1500=(75n+1500)-1500\\7125=75n[/tex]

Now divide both sides by 75:

[tex](7125)/75=(75n)/75\\n=95[/tex]

Thus, a total of 95 people attended the wedding.

Small X^2 value, large p-value

=================================================

Explanation:

The X^2 refers to chi-squared or chi-square value.

If the observed and expected values are close, then their differences are small leading to small squares of those differences. Consequently, this means the sum of the squared differences is also small leading to a small X^2 value.

The p-value is the probability of getting a certain chi-square value or larger. If X^2 is small, then we have a very large chance of getting that certain X^2 value or larger. Visually, the area under the chi-square curve to the right of X^2 will be large if X^2 is small.

A large p-value means we fail to reject the null hypothesis. You can think of the p-value as the probability that the null is correct (though because of some technical reasons it's not this entirely, but its close enough). This means a large p-value tells us to accept that the data fits the distribution we're trying to compare to.

In this exercise we have to use probability knowledge so we can say that the correct alternative is:

Letter B

Answer:

B) y = -9.98×10⁻⁵ x + 13.95

C) 0.1

Step-by-step explanation:

Using Excel, the least squares regression line, rounded to two decimal places, is y = -9.98×10⁻⁵ x + 13.95.

The slope is -9.98×10⁻⁵, so if x increases by 1000, then y changes by -9.98×10⁻² = -0.0998.  Rounded to one decimal place, the ulcer rate per 100 population will go down by 0.1 points.

A fraction is a whole number that expresses a certain number of portions that are taken from a whole divided into parts.

It is represented by a bar that separates the first part (numerator) from the second (denominator).

The numerator represents the number of parts taken and the denominator represents the entire element.

For example, 3 eaten parts of a 4-piece cake.

3/4 of the cake was eaten.

Answer:

4,428 books

Step-by-step explanation:

make the equation 57,641+10x=16,682+19.25x

(you’re using that equation because the numbers have to be equal at the end. also “x” is the variable) after that subtract 16,682 from both sides that should give you (40,959+10x= 19.25x) after that subtract 10x from both sides, that should give you (40,959 = 9.25x) Lastly divide both sides by 9.25 and you should get x=4,428.

Answer:

if q is odd

Step-by-step explanation:

Hello,

Either q is odd or is even.

Case 1 - we can find k integer so that q = 2k

Then, in the case

[tex]q^2-1=4k^2-1[/tex]

This is not divisible by 8, for instance, q = 6

[tex]q^2-1=36-1=35=7*5[/tex]

Case 2 - we can find k integer so that q = 2k+1

[tex]q^2-1=(2k+1)^2-1=4k^2+4k+1-1=4k(k+1)[/tex]

k(k+1) is divisible by 2 so the initial number is divisible by 8

Conclusion, the answer is q is odd.

Thanks
