In a Survey at a local university 69% of students so that they get less than the recommended eight hours of sleep per night. In a group of 4800 students how many would you expect to get eight or more hours of sleep per night

Answer:

1 unit to the right of 0

Step-by-step explanation:

Well if you distribute the - into the (-1) than you should get a positive becuase -1*-1 is positive 1. So it would be right next to 0 to the right.

Answer:

If a set of points is a function, the elements of the set must have the same number of elements.

For example, if the function is from A→B, the elements must be ordered pairs.

So Y is not a function.

---------------------------------------------------------------------------------------------

If Y is in fact  {(2, 6), (3, 1), (4, 1), (5, 6)}

then Y is a function, because each of the first coordinates appears only once.

In functional notation, we have f(2)=6, f(3)=1 etc....

remark: if a first coordinate is repeated, for example if we have (2, 6) and also (2, 8)

this would mean f(2)=6, but also f(2)=8, which means f is not a function.

Answer:

8 and -7

Step-by-step explanation:

Note that multiplication is commutative, in simpler terms, the order of multiplication doesn't matter at all. We shall use this to solve the problem.

[tex](-4)\times(-3\frac{5}{6} )= (-4)\times(-3)\times(\frac{5}{6})[/tex]

Now, what we also know is that a negative number times a negative number is a positive number. And we also know that 4 times 3 is 12.

So,

Writing the same thing in a more convenient way:

[tex]12\times\frac{5}{6} = 12\frac{5}{6}[/tex]

So the answer is the second alternative

Answer:

24.61

Step-by-step explanation:

7% of 23 is 1.61

so add 1.61 to 23 = 24.61

Answer: statistically significant

Step-by-step explanation:

The p-value of a statistical test tell us the conclusion to our hypothesis. When the result of the p-value lies between 0.27 it means there is a 27% chance of it occurring, when it is at 0.02 it means there is a 2% chance of it occurring. When it lies between 0.0027 it means there is 0.27 chance of it occurring this becomes statistically significant as this won’t have much changes or effects on the hypothesis. So what this means is there is chance it won’t occur.

Answer: the answer is 6)

Step-by-step explanation:

Because [tex]2x^{-4}[/tex] . [tex]2x^{2}[/tex] = [tex]2x^{-4+2}[/tex] = [tex]2x^{-2}[/tex]

I hope it right

Answer:

18.38 B

Step-by-step explanation:

let x be the cost of 3.5 pounds

5.25/1 = x/3.5

5.25=x/3.5

18.375=x

since you can't buy 3.5 pounds with 18.37 (1 penny short), you need 18.28

Step-by-step explanation:

6.6.6.6

Answer:

1.08 is the constant of proportionality.

Step-by-step explanation:

The constant value (often written k) relating amounts that rise or fall uniformly together.

It is the ratio of the amounts y and x:

k = y/x

Put another way: y = kx

Example: you are paid $20 an hour

The constant of proportionality is 20 because: Pay = 20 × Hours worked

Answer:61mph

Step-by-step explanation:

152.5/2.5=61

Answer:

Easy, it's 61miles per hour

Step-by-step explanation:

Answer:

25%

Step-by-step explanation:

Initial no of students = 16,000

Final no of students = 20,000

We need to find the percent increase in enrollment.

The increase in no of students = 20,000 - 16,000

= 4000

Percentage = (increase/initial no of students) × 100

[tex]\%=\dfrac{4000}{16000}\times 100\\\\=25\%[/tex]

Hence, the percent increase is 25%.

Answer:

y=-4x-4

Step-by-step explanation:

m=-4

point(-2,4)

y-4 = -4 (x- (-2) )

y-4 = -4 (x+2)

y-4 = -4x -8

y = -4x -4

Step-by-step explanation:

we are going to use quadratic equation for this particular question . so now we are going to change the signs i.e from negative to positive or from positive to negative(-2 will turns to +2) nd +4 will turns to-4)

therefore, (x+2)(x-4) then we na expand the bracket x(x-4)+2(x-4)

x square -4x+2x-8

therefore the equation is nothing but x square-2x-8
