Answer:

Calculating (5 x 2) violates the order of operations

Step-by-step explanation:

According to the order of operations, multiplies all have equal priority. Therefore, they must be evaluated left to right, not right to left. Evaluating (5 x 2) first is incorrect, and instead (9 x 5) should be calculated first.

Graph the function y=2 sqrt x+4 and state the transformation from the parent graph y= sqrt x
Darya [45]

Answer:

Step-by-step explanation:

Please use parentheses so that there's no question about what constitutes the argument of the sqrt function:

y=2 sqrt x+4 → y = 2√(x + 4)

This result is obtained from y = √x by:

1) translating the graph of y = √x 4 units to the LEFT, and

2) stretching the resulting graph vertically by a factor of 2.

stira [4]

Answer:

0.2384 = 23.84% probability that 3 were laser printers.

Step-by-step explanation:

The printers will be chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

20 orders means that N = 8

8 were laser printers, which means that k = 8

Sample of 5 means that n = 5

What is the probability that 3 were laser printers?

This is P(X = 3).

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}

P(X = 3) = h(3,20,5,8) = \frac{C_{8,3}*C_{12,2}}{C_{20,5}} = 0.2384

0.2384 = 23.84% probability that 3 were laser printers.
