Before polling the students in Scion School of Business, a researcher divides all the current students into groups based on their class standing, such as freshman, sophomore, and so on. Then, she randomly draws a sample of 50 students from each of these groups to create a representative sample of the entire body in the school.

Answer:

D

Step-by-step explanation:

because the angles are across from each other, they are equivalent

you would set up the equation like this

8x - 8 = 7x + 8

then you could add 8 to each side

8x = 7x + 16

then subtract 7x from each side

x = 16

Answer:

[tex]\displaystyle f(x) = \ln\left( 1 + x^2\right)[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle e^{f(x)} = 1 + x^2[/tex]

And we want to find f(x).

We can take the natural log of both sides:

[tex]\displaystyle \ln\left(e^{f(x)}\right) = \ln\left( 1 + x^2\right)[/tex]

Recall that ln(aᵇ) = bln(a). Hence:

[tex]\displaystyle f(x) \ln(e) = \ln\left ( 1 + x^2\right)[/tex]

By definition ln(e) = 1. Therefore:

[tex]\displaystyle f(x) = \ln\left( 1 + x^2\right)[/tex]

Answer:

c = 9 - a + b

Step-by-step explanation:

root square(a - b + c) = 3

a - b + c = 3^2

a - b + c = 9

solving for c

c= 9 - a + b

Answer:

[tex] r = \frac{tw}{(t - 1)} [/tex]

Step-by-step explanation:

[tex]t = \frac{r}{(r - w)} \\ t(r - w) = r \\ tr - tw = r \\ tr - r = tw \\ r(t - 1) = tw \\ \frac{r(t - 1)}{(t - 1)} = \frac{tw}{(t - 1)} \\ r = \frac{tw}{(t - 1)} [/tex]

Answer:

-8 <_ x < -3

-7 <_ y < -2

Step-by-step explanation:

closed dot means it includes that number so in this case x is least than or equal to -8 and open dot means it doesn't include that value so x is less than -3 and does NOT include -3

and for the y value it's pretty self explanatory if u just count it (i might be off by a little cuz the photo quality is kinda fuzzy but i hope u get the gist!)

Step-by-step explanation:

9x - 2 = 5x + 54

9x - 5x = 54 + 2

4x = 56

x = 14

(9x - 2) + (10y + 6) = 180

(9 · 14 - 2) + 10y + 6 = 180

126 - 2 + 10y + 6 = 180

130 + 10y = 180

10y = 180 - 130

10y = 50

y = 5

Answer:

c = -1/4

e = 1 2/5

Step-by-step explanation:

4c - 5 = -6

add 5 to both sides

4c = -1

divide each side by 4

c = -1/4

5e + 2 = 9

subtract 2 from both sides

5e = 7

divide both sides by 5

e = 1 2/5

-Chetan K

Answer:

c = -1/4

e = 7/5

Step-by-step explanation:

1. 4c - 5 = -6, 4c = -1, c = -1/4

2. 5e + 2 = 9, 5e = 7, e = 7/5

Answer: Every answer choice is to be selected

Explanation:

The following angles are adjacent to angle 8

Adjacent angles share a common line segment, line, or ray. Think of it like a shared wall. The other remaining angles are non-adjacent even though something like angle 6 shares a common vertex with angle 8, they don't share a common wall. In a sense, the person living in apartment 6 isn't a direct next door neighbor to the person in apartment 8.

So that's why we select angles 2, 4, 5, 1 and 3 as our answers. In short, we click each box to select all answer options.

Answer:

4/3 lemons

Step-by-step explanation:

For 16 lemons per 12 cups, simplify the ratio to 4 lemons per 3 cups.

The required rate of lemon per cup of lemonade is 1.34 lemons per cup.

Given that,
For Allison's lemonade recipe, 16 lemons are required to make 12 cups of lemonade. At what rate are lemons being used in lemons per cup of lemonade to be determined.

The rate of change is defined as the change in value with the rest of the time is called the rate of change.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Since
Let the rate of lemon per cup of lemonade is x,
Total lemon = 16
To a cup of lemonade = 12
Rate of lemon per cup of lemonade
x = 16/12
x = 1.34

Thus, the required rate of lemon per cup of lemonade is 1.34 lemons per cup.

Answer:

252, 259 and 266

Step-by-step explanation:

Multiples of a number are those numbers that are divisible by that. Like if x and y are any two numbers then if y is a multiple of x then the remainder should be equal to zero when x is divided from y.

Answer:

Three consecutive multiples of 7 whose sum is equal to 777 are 252, 259 and 266.
