What is the probability of getting more than 60 heads in 100 tosses?

On a coin there is 2 sides so there is an even chance so if it’s 50 / 50 you would have to do more than 100 tosses to get over 60 heads

100 coin tosses form a binomial distribution with number of trials = 100 and probability of success = 0.5

The probability of getting more than 60 heads in 100 tosses is P(X > 60), which can be evaluated by summing up the individual probabilities for X = 61 to 100. This gives 0.0176 or 1.76%.

What is the name of the segment inside the large triangle? (had to ask again because i forgot the answer choices with my choice)

Greeley [361]

The answer is Angle Bisector.
I think this because if it were to be perpendicular the triangle would have to be congruent in SSS theorem or other.
I hope this helps!

Perpendicular=P=4
Base=B=4

Hypotenuse be H

Apply Pythagorean theorem

$\\ \tt\hookrightarrow H^2=P^2+B^2$

$\\ \tt\hookrightarrow H^2=4^2+4^2$

$\\ \tt\hookrightarrow H^2=32$

$\\ \tt\hookrightarrow H=\sqrt{32}$

$\\ \tt\hookrightarrow H=5.8units$

Dr. Brown did 6 experiments at 7AM. Dr. Rachal did 8 experiments at 6PM. They both had 564 tools each. Dr. Brown used 386 and Dr

devlian [24]

Answer:

Step-by-step explanation:

Total number of tools for both = 564.

Dr Brown used 386 tools for 6 experiments.

average number of tools per experiment used by Dr Brown = $\frac{386}{6}$

= 64 $\frac{1}{3}$

Dr Rachal used 236 tools for 8 experiments.

average number of tools per experiment used by Dr Rachal = $\frac{236}{8}$

= 29 $\frac{1}{2}$

i. The number of more experiment that can be done by Dr Brown = (564 - 386) ÷ (64 $\frac{1}{3}$ )

= 2.7668

Dr Brown can do two more experiments.

The number of more experiments that can be done by Dr Rachal = (564 - 236) ÷ (29 $\frac{1}{2}$ )

= 11.1186

Dr Rachal can do 11 more experiments.

ii. Number of tools left after Dr Brown's experiments = 564 - 386

= 178

Number of tools left after Dr Rachal's experiments = 564 - 236

= 328
