Javier read a report that said the probability that a randomly selected American is left-handed is 14\%14%14, percent. He was cu

rious how many left-handed students to expect in a class of 303030 students. He simulated 100100100 classes of 303030 students where each student selected had a 0.140.140, point, 14 probability of being left-handed. Javier counted how many left-handed students were in each simulated class. Here are his results: Use his results to estimate the probability that there are 777 or more left-handed students in a class of 303030 students. Give your answer as either a fraction or a decimal.

= 0.1165 Step-by-step explanation: In statistics, the binomial distribution involves two possible outcomes. With ''n'' representing the number of trials in an experiment, these tables can be utilized to find the probability of achieving a specific number of successes within the experiment. P=14% = 0.14, n=30. Here, binomial distribution cumulative tables are applied. Thus, P(More than 7) = P(x > 7) = 1 - P(x < 7) = 1 - P(x ≤ 6) = 1 - 0.8835 = 0.1165.

Which rule describes the composition of transformations that maps ΔABC to ΔA"B"C"?
babunello [8423]

Answer:

The transformation is a reflection over the x-axis followed by a translation 6 units left and 2 units down.

Step-by-step explanation:

To determine the order of transformations from ΔABC to ΔA"B"C", note that the figure first changes to ΔA'B'C', and then to ΔA''B''C''.

The transition from ΔABC to ΔA'B'C' involves a reflection over the x-axis, as ΔA'B'C' appears as a mirror image flipped vertically.

Next, moving from ΔA'B'C' to ΔA''B''C'' entails shifting the figure left by 6 units and downward by 2 units. This matches a translation by -6 in the x direction and -2 in the y direction.

Thus, the accurate description is:

Reflection across the x-axis followed by a translation of -6 units in x and -2 units in y.

The graph below shows the solution to which system of inequalities?
Zina [9179]
The solution is C. Let’s start by identifying the equations without inequalities. Since there's a dotted line at y = 1, options A and B can be disregarded. Dotted lines indicate exclusivity, so they do not encompass the = sign. Therefore, the answer must be C.

If m abf=7b-24 and m Abe = 2b what is m EBF
Inessa [9006]
Since m∠abe = 2b, and angle abe consists of angles abf and ebf, we can write:
m∠abe = m∠abf + m∠ebf
To find m∠ebf, rearrange:
m∠ebf = m∠abe - m∠abf
Substitute the given expressions:
m∠ebf = 2b - (7b - 24)
Simplify:
m∠ebf = 2b - 7b + 24
m∠ebf = -5b + 24.

PIT_PIT [9121]
12-5x-4kx=y:x 

-5x-4kx=y-12 

-x(5+4k)=y-12 

-x= \dfrac{y-12}{5+4k} 

x=- \dfrac{y-12}{5+4k}
