You can remove alphabet S from SEVEN.

You can change the convention. Whole mathematics works like that. After all it is just a name, ie, call the numbers divisible by 2 odd and not divisible by 2 even. Everything will still work fine. You got to rename some theorems also.

Introduce and derive a new number system from the current number system, name the symbol 6 as seven and the symbol 7 as Six. Just rename the symbols.

Introducing a new number system and interchange position of 7 with an even number.

If we remove one number before 7 ( 1 - 6 ) with its name, we have again a new number system with base 9 and technically no. 7 is still no. 7 with value = 6.

These are some genuine ways rather than dividing.

ANSWERS OF DIVISION ARE TECHNICALLY WRONG AND RIDICULOUS BECAUSE DIVISION BY ‘x’ is MULTIPLICATION BY ‘1/x’ .

The owner of a deli gathered data about the number of flavored bagels and plain bagels sold during the first hour of business fo

pychu [463]

Answer:

Approximately 25 flavored bagels.

Step-by-step explanation:

The scatter plot is a graph on cartesian plane where;

y-axis represents the number of plain bagels sold.

x-axis representing the number of flavored bagels sold.

The equation of the straight line on the graph is;

y = 1.731x + 6.697

The graph formed is as attached below.

The slope of the graph means that for every 1 flavored bagel sold, 1.731 plain bagels are sold within one hour.

When y = 50 ;

50 = 1.731x + 6.697

x = $\frac{50 - 6.697}{1.731}$ = 25.01617562 ≈ 25 flavored bagels.

In a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less. A local man cl

Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

Given that in a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less.

The sample size n = 80

no of wells less than 100 feet deep=27

Sample proportion = $\frac{27}{80} =0.3375$

a) Create hypotheses as

$H_0: p = 0.30\\H_a: p >0.30\\$

(Right tailed test)

p difference $= 0.3375-0.30 = 0.0375$

Std error of p = $\sqrt{\frac{0.3(0.7)}{80} } =0.0512$

b) Assumptions: Each trial is independent and np and nq >5

c) Z test can be used.

Z= p diff/std error = $\frac{0.0375}{0.0512} =0.73$

p value = 0.233

d) p value is the probability for which null hypothesis is false.

e) Conclusion: Since p >0.05 we accept null hypothesis

there is no statistical evidence which support the claim that more than 30% are drilled.

How do I solve<br> -3x+y=24<br> -2x=+18+5y

ExtremeBDS [4]

Answer:

Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.

18x−21y=24

−18x+10y=−2

Add the two equations.

−11y=22

Divide by -11 to isolate y.

y=−2

Substitute y=−2 into either of the 2 equations, I'll just use the second one.

9x+10=1

9x=−9

x=−1

Step-by-step explanation: that is your anwser

Is D because you set x to 0 or you set y to 0, if you set x to 0 then y will be 5. (X,5) so is D
