Using the TI-84 calculator, find the area under the standard normal curve. Round the answers to four decimal places.

(a) Find the area under the standard normal curve that lies between z= −2.39 and z= −1.27.

(b) Find the area under the standard normal curve that lies outside the interval between z= −1.36 and z= 1.68.

(c) Find the area under the standard normal curve to the left of z= 0.74.

(d) Find the area under the standard normal curve to the right of z= 1.17.

Given: pqrs is a parallelogram prove: pr and qs bisect each other at t

This is a map of the mars exploration rover opportunity predicted landing site on mars. the scale is 1cm : 9.4km. what are the approximate measures of the actual length and width of the ellipse? i mostly need to know how to set it up : )

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
