g Suppose we want to know what proportion p of students in a large university have studied calculus in high school. At least how many students should we include in a sample if we want to estimate p with an error bound of 0.03 (at most) with 95% confidence

Answers

Answer:

1067

Step-by-step explanation:

Given that:

Error (E) = 0.03

Confidence interval = 95% = 0.95

Sample size (n) = ((Zα/2) / Error)^2 * p(1 - p)

Since no assumption is given ; p = 0.5

α = 0.95

Z(1-α/2) = 1.96

(1.96 / 0.03)^2 * 0.5(1 - 0.5)

(65.333333)^2 * 0.5(0.5)

4268.4444 * 0.25

= 1067.1111

n = 1067

Answers

Answer:

N = [tex]\frac{3}{4}[/tex] * v

Step-by-step explanation:

Since the value that we are provided is a fraction that is tied to the number of books that Victor has, we would simply need to multiply this fraction by the total number of books that Victor has. This value is represented by the variable v while the total number of books that Nora has is represented by the variable N. Therefore, the expression would be the following

N = [tex]\frac{3}{4}[/tex] * v

20) Solve the problem. Suppose that 12 unique names are put into a hat and drawn at random without
replacement. How many different ways can you draw all of the names from the hat? Remember that
"without replacement" means that the names are not returned to the hat after they are chosen. Write your
answer in factorial notation.
SHOW WORK: None to be shown
A) 12!
B) 11!
C) 10!
D) 12! - 1

Answers

the answer would be A) 12 because there are only twelve names

The number of different ways is 12! you can draw all of the names from the hat without replacement option (A) 12! is correct.

What are permutation and combination?

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

It is given that:

Number of unique names = 12

That 12 unique names are put into a hat and drawn at random without

replacement.

"Without replacement" means that the names are not returned to the hat after they are chosen.

Number ways (without replacement) = 12x11x10x9x8x7x6x5x4x3x2x1

Number ways (without replacement) = 12!

Thus, the number of different ways is 12! you can draw all of the names from the hat without replacement option (A) 12! is correct.

PLEASE HELP MEEEEE FASTTT

Answers

Answer:

-63

Step-by-step explanation:

PEMDAS stands for:

P -> Parentheses

E -> Exponents

M -> Multiplication (left to right)

D -> Division (left to right)

A -> Addition (left to right)

S -> Subtraction (left to right)

So in this problem, we can't evaluate the parentheses unless we evaluate the exponent first:

(-25+4^2)*7

(-25+16)*7

Next, we evaluate the parentheses by adding from left to right since there's no multiplication or division in the parentheses:

(-25+16)*7

(-9)*7

Lastly, we do multiplication:

(-9)*7

-63

Thus, our final answer is -63

Solution,

Use the formula as follows :

y = mx+b

Put x = -5 and y = -8

[tex]-8=\dfrac{-6}{7}(-5)+b\\\\b=-8-\dfrac{6}{7}\times 5\\\\b=-12.28\\\\=-\dfrac{86}{7}[/tex]

So, the equation of line is :
