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.

Answer:

= 0.1165

Step-by-step explanation:

In statistics, binomial distribution table  are ones in which one of two outcomes may result. Given the number of trials in an experiment ''n'', you can use these binomial distribution tables to look up the probability of a certain number of successes in the whole experiment.

P=14% = 0.14, n=30

Here we can use binomial distribution use binomial cumulative tables

Then P(More than 7) = P(x>7)

= 1 - P(x < 7)

= 1 - P(x ≤ 6)

= 1 - 0.8835

= 0.1165

In radian measure, the angles of a 30-60-90 triangle are;
blagie [28]
We know that
180 degrees is equal to pi radians
so
for 30 degrees
180°--------> pi radians
30°--------> x
x=30*pi/180------> x=pi/6 radians

for 60 degrees
180°--------> pi radians
60°--------> x
x=60*pi/180------> x=pi/3 radians

for 90 degrees
180°--------> pi radians
90°--------> x
x=90*pi/180------> x=pi/2 radians

the answer is the option c
pi/6,pi/3,pi/2

Let h(x)=2x+5h(x)=2x+5h, left parenthesis, x, right parenthesis, equals, 2, x, plus, 5 and g(x)=8-3xg(x)=8−3xg, left parenthesis
BaLLatris [955]
The question is Let h(x)=2x+5  and <span>g(x)=8-3x
what is the value of </span><span>h(g(1.5))
 the answer 

</span>h(g(1.5))= 2g(1.5)+5, and <span>g(1.5)=8-3(1.5)=3.5, so
</span>h(g(1.5))= 2<span>(3.5)+5= 12
</span>h(g(1.5))= 12
