Answer:

a) 0.705

b) 0.976

c) 0.01

d) 0.09

Step-by-step explanation:

We have to find the area under the standard normal curve.

a) area under the standard normal curve that lies outside the interval between z= −1.98 and z=0.61.

=P(-1.98

b) area under the standard normal curve to the left of z=1.98

=P(z

c) area under the standard normal curve to the right of z= 2.34

P(z>2.34)\\=1 - P(z

d)  area under the standard normal curve that lies between z= −0.94 and z= −0.63

=P(-0.94

Select all intervals in which the function P(t) is decreasing
Irina-Kira [14]

Answer:

we conclude that the intervals in which the function P(t) is decreasing are:

  • x < 1
  • 3 < x < 4

Step-by-step explanation:

At x< 1, the function P(t) is decreasing

  • A function p is an increasing function on an open interval if f(y) > f(x) for any two input values x and y in the given interval where y>x
  • A function p is a decreasing function on an open interval if f(y) > f(x) for any two input values x and y in the given interval where y>x

From the figure, it is clear that the function seems to be increasing

from (1, 3) and then 4 to onwards.

But it is clear that the function seems to be decreasing from the x < 1 and from the interval (3, 4).

Therefore, we conclude that the intervals in which the function P(t) is decreasing are:

  • x < 1
  • 3 < x < 4
