Answer:

Step-by-step explanation:

Given that the  mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

X is N(25, 1)

a) Normal curve is in the attached file

b) the probability that a randomly selected fertilized egg hatches in less than 23 days

=P(X

we convert x into Z score and use std normal distn table to find probability

P(X

i.e. we can say only 2.5% proportion will hatch in less than 23 days.

Can somebody help me

cis(x)=\cos x+i\sin x\\\\cis15^o=\cos15^o+i\sin15^o\\\\\cos15^o=\dfrac{\sqrt6+\sqrt2}{4};\ \sin15^o=\dfrac{\sqrt6-\sqrt2}{4}\\\\\text{therefore}\\\\7cis15^o=7\left(\cos15^o+i\sin15^o\right)=7\cos15^o+7i\sin15^o\\\\=7\left(\dfrac{\sqrt6+\sqrt2}{4}\right)+7\left(\dfrac{\sqrt6-\sqrt2}{4}\right)i

Where is the function increasing?<br> A)1 B)3&lt; X C)-infinity &lt; x &lt; 1<br> D)-infinity
eduard

Answer:

A) 1

Step-by-step explanation:

Given:

A graph of a function.

When we analyze the given graph, it is of a <em>parabola</em>.

To find:

The interval of values of x where the function is increasing.

Solution:

First of all, let us learn about the meaning of increasing and decreasing functions.

1. A function y=f(x) is known as increasing  in an interval a when

Value of y keeps on increasing when we move from the value of x from a to b.

2. A function y=f(x) is known as decreasing  in an interval a when

Value of y keeps on decreasing when we move from the value of x from a to b.

On analyzing the given graph , we can see that the graph is decreasing on the interval: -\infty

and is increasing on the interval: 1

When we choose from the options,

The correct answer is option A) 1
