(Math) Valentina purchased 200 beads for $48 to make necklaces. If she needs to buy 25 more beads, how much will she pay if she

Answer:

Step-by-step explanation:

The total count of laptops, N = 20

Defective laptops, n = 3

The school is purchasing 2 laptops

Case 1:

Both purchased laptops are non-defective

Probability of selecting 2 non-defective laptops

The count of non-defective laptops equals 20 - 3 = 17

Overall laptop count = 20

Probability, P = 17/20 = 0.85

Case 2:

One laptop is found defective

The probability of choosing 1 defective and 1 non-defective laptop

P' = 3/20 x 17/19 = 0.134

Case 3:

Both laptops are defective

Choosing 2 laptops from 3 = 3 C 2 = 3

Selecting 2 from 20 = 20 C 2 = 190

The probability of selecting two defective laptops equals 3 / 190 = 0.0158

P'' =

The function is applicable within the segments of x:
(-∞, -1) and [-1, 7), meaning it is valid for x < 7.

Importantly,
the function cannot be evaluated at x = -1 in the left part of the linear graph, while it is valid at x = -1 in the right segment of the same line. Additionally, the function is not defined at x = 7 or any value above it.

Conclusion: x < 7.

Answer:

The charge is a flat rate of 20 dollars, with an additional 5 dollars for every hour worked =

20+h5

Step-by-step explanation:

Answer:

Detailed explanation:

The sample consists of only 20 individuals, which is insufficient. A minimum of 30 is recommended for a sample size.

Also, the ideal maximum size should not exceed 10% of the total population. Calculating it gives us,

10/100 × 500 = 50

So, this criterion is satisfied.

Thus, the condition not satisfied for inference is that

The sample size must be large enough to presume normality in the distribution of the sample means.

The appropriate choice is

A. II only

Result: 4m

Detailed explanation:

Important note: midpoints split a line into equal halves.

To find the length of SA;

We observe the larger triangle QRS, which includes

Two midpoints:

A located on line QS, QA = 4m;

and B on line RS where RB = 3m

Based on the midpoint definition:

QS = QA + AS

where QA = AS

QS = 2QA = 2AS

Hence,

QA = QS

4m = 4m
