Answer:

The first one

Step-by-step explanation:

When you do a reflection across the y-axis, it is like a mirror. And if you have a generic point (x, y) the new point will be (-x, y).

In the table you have 4 points:

(x,y)

(-3,9)

(0,0)

(2,4)

(5,25)

The new points will be:

(3,9)

(0,0)

(-2,4)

(-5,25)

alekssr [168]

Answer:

0.0923 = 9.23% probability that four of the patients are still alive after five years.

Step-by-step explanation:

For each patient, there are only two possible outcomes. Either they are still alive after five years, or they are not. The probability of a patient being alive is independent of any other patient, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which 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)!}

And p is the probability of X happening.

Po is an oncologist with seven patients in their care.

This means that n = 7

The probability that a patient will survive five years after being diagnosed with stage three breast cancer is 0.82.

This means that p = 0.82

What is the probability that four of the patients are still alive after five years?

This is P(X = 4). So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 4) = C_{7,4}.(0.82)^{4}.(0.18)^{3} = 0.0923

0.0923 = 9.23% probability that four of the patients are still alive after five years.

Tina is joining 3 sections of a quilt. Each section has 3 rows of 15 square pieces of fabric. How many squares will be in the co
Tomtit [17]

Answer: There are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.

Step-by-step explanation:

Since we have given that

Number of sections = 3

Number of rows in each sections = 3

Number of square pieces in each row = 15

So, the number of squares that will be in the completed quilt would be

3\times 3\times 15\\\\=9\times 15\\\\=135

Hence, there are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.
