The final scores of students in mathematics are distributed normally with a mean of 72 and a standard deviation of 10. What is the probability that a student’s score will be between 65 and 78?.
Answer:
0.8041
Explanation:
0.8041
We know that
μ=72 and σ=5
and P(65<X<78)
We can determine the Z value as (X-μ)/σ
P( 65<X<78 )=P( 65-72< X-μ<78-72)
P((65-72)/5 < Z < (78-72)/5)P((65−72)/5<Z<(78−72)/5)
P(65 < X < 78 )=P(-1.4 < Z < 1.2)P(65<X<78)=P(−1.4<Z<1.2)
To fine the Z values:
P (-1.4 < Z < 1.2 )=P ( Z < 1.2 )-P (Z < -1.4 )P(−1.4<Z<1.2)=P(Z<1.2)−P(Z<−1.4)
From the standard normal tables:
P (Z < 1.2 )=0.8849P(Z<1.2)=0.8849
to find P ( Z<-1.4)
P ( Z < -a)=1-P ( Z < a )P(Z<−a)=1−P(Z<a)
From the standard normal tables:
P ( Z < -1.4)=1-P ( Z < 1.4 )=1-0.9192=0.0808P(Z<−1.4)=1−P(Z<1.4)=1−0.9192=0.0808
Therefore
P(-1.4 < Z < 1.2 )=0.8041P(−1.4<Z<1.2)=0.8041
P (65 < X < 78)=0.8041P(65<X<78)=0.8041

Hydrogen chloride gas can be prepared by the following reaction.
Answer: Hydrogen chloride may be formed by the direct combination of chlorine (Cl 2) gas and hydrogen (H 2) gas; the reaction is rapid at temperatures above 250 °C (482 °F). The reaction, represented by the equation H 2 + Cl 2 → 2HCl, is accompanied by evolution of heat and appears to be accelerated by moisture.

Which best describes the activity of the reading brain in proficient readers, compared to beginning readers?.
A good description which differentiates the brain of proficient readers from that of beginning readers is deeper cognitive function and brain development.
Proficient readers are expected to have a more developed brain which has been aided by long period of reading exercises and practice, hence allowing the brain to master and develop accordingly. Beginning readers would often find it difficult to exercise the same level of reading skill exhibited by proficient readers due to lack of reading experience.However, with time the brain of beginning readers begin to develop, allowing it to take complex reading actions with practice.
