Answer:

angle BCD = 108

Step-by-step explanation:

opposite angles in a cyclic quadrilateral add to 180

so angle BDC is 180 - 72 = 108

what are the angles 32 and 114 there for??

The complete question in the attached figure

we have that
between beats 2 and 3----------> (392-261.6)=130.4-------> increases
between beats 3 and 4----------> (392-392)=0-----> <span>it stays with the same value
</span>between beats 4 and 5----------> (444-392)=52--------> increases
between beats 5 and 6----------> (444-444)=0-----> it stays with the same value
between beats 6 and 7----------> (392-444)=-52-------> decreases

the answer is
between beats 6 and 7----------> (392-444)=-52-------> decreases

How do I do this question

Alekssandra [29.7K]

We know that
circumference=2*pi*r
for r=65/2----> r=32.5 cm
circumference=2*pi*32.5-----> 204.1 cm
so
one revolution <span>of Emma’s bicycle</span> is equal to 204.1 cm-----> 2.041 m
3.2 km-------> 3200 m
1 revolution---------> 2.041 m
x rev------------> 3200 m
x=3200/2.041 ----> x=1567.86 revolutions

the answer is
1567 complete revolutions

Tom is throwing darts at a target. In his last 30 throws, Tom has hit the target 20 times. You want to know the estimated probab

Musya8 [376]

Each scenario can be used to simulate probability, and there are 3 correct scenarios and 2 incorrect scenarios in the list of options

<h3>How to categorize the simulations?</h3>

From the question, we have the following parameters:

Number of throws = 30
Number of hits = 20

This means that the probability of hit is:

P(Hit) = 20/30

Simplify

P(Hit) = 2/3

Using the complement rule,

P(Miss) = 1/3

The above means that the simulation that represents the situation must have the following parameters:

P(Success) = 2/3
P(Failure) = 1/3
Number of experiments = 3

Using the above highlights, the correct scenarios are:

Rolling a die three times with numbers 1 to 4 representing a hit
Spinner a spinner of 3 equal sections three times with two sections representing hit
Spinner a spinner of 6 equal sections three times with four sections representing hit
