Answer:

33

Step-by-step explanation:

The two angles are vertical angles so the angle opposite angle 1 is the same as angle 1 .  We will call it angle 1 as well

<1 + <1 + 114 = 180 because it forms a semi circle

2 <1 + 114 = 180

Subtract 114 from each side

2 <1 = 180-114

2 <1 = 66

Divide each side by 2

<1 = 66/2

<1 = 33

Given:   IQ test have a​ bell-shaped distribution with a mean of 100 and a standard deviation of 19.

Since , the graph of normal distribution is bell-shaped , it mean that IQ scores follow normal distribution.

Then, About 99.7%  IQ scores falls within Mean ± 3 (Standard deviation).

i.e. About 99.7%  IQ scores falls within 100± 3(19).

i.e. About 99.7%  IQ scores falls within 100- 57 and 100+57.

i.e. About 99.7%  IQ scores falls within 43 and 157.

Therefore , by empirical rule

1.The growth of a sample of bacteria can be modeled by the function b(t)=100(1.06)t where b is the number of bacteria and t is t
qwelly [4]

Given:

The growth of a sample of bacteria can be modeled by the function

b(t)=100(1.06)^t

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

b(t)=100(1.06)^t

Here, b(t) number of total bacteria after t hours.

Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.

b(t)=100(1.06)^3

b(t)=100(1.191016)

b(t)=119.1016&#10;

Therefore, the number of total bacteria after 3 hours is 119.1016.
