Find The Size Of The Angle 3x.3x=

Answers

Answer 1

Answer:

60 degrees

Step-by-step explanation:

a straight line is 180 degrees

2x= 120 degrees

x=60 degrees

Answer 2

Answer:

The value of x is 60°

Step-by-step explanation:

For a given Straight Line

We know that, The straight angle is an angle equal to 180°

So,

3x = 180

Divide by 3 from both side

3x/3 = 180/3

x = 60°

Thus, The value of x is 60°

Given P(A)=0.64P(A)=0.64, P(B)=0.4P(B)=0.4 and P(A\cap B)=0.356P(A∩B)=0.356, find the value of P(A\cup B)P(A∪B), rounding to the nearest thousandth, if necessary.

Answers

Answer:

Step-by-step explanation:

P(A U B) = P (A) + P (B) - P (A and B)

= 0.64 + 0.4 - 0.356

= 0.684

The value of P(A∪B) is 0.684

What is probability?

Probabilities are used to determine the chances of events

The given parameters are:

P(A)=0.64,

P(B)=0.4

P(A∩B)=0.356

To find the value of P(A∪B), we make use of the following formula

P(A∪B) = P(A) + P(B) - P(A∩B)

So, we have:

P(A∪B) = 0.64 + 0.4 - 0.356

Evaluate the expression

P(A∪B) = 0.684

Hence, the value of P(A∪B) is 0.684

Find the length of all segments in the triangle
Find LA, AE, SL

Answers

AE= 6.93 - 4.63 = 2.3 cm

LA: a2 + b2 = c2
(3.26)2 + (2.3)2 = LA2
10.63 + 5.29 = LA2
15.92 = LA2
sqrt 15.92 = LA
So, LA= 3.98 cm


LS: a2 + b2 = c2
(3.98)2 + (b)2 = (6.93)2
b = sqrt (6.93)2 - (3.98)2
So, LS = 5.67 cm

Step-by-step explanation:

First, let's start with the formula for the surface area of a rectangular prism.

A = 2(wl + hl + hw)

Plug in everything that you know.

A = 2[(4 · 5) + (7 · 5) + (7 · 4)]

Simply the equation.

A = 2(20 + 35 + 28)

A = 2(73)

wrongsubject Which conditions are needed for a hurricane to form?


A.

warm, dry air rising over warm areas on the land


B.

warm, dry air rising over warm areas in the ocean


C.

warm, moist air rising over warm areas on the land


D.

warm, moist air rising over warm areas in the ocean

Answers

The answer is D

For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.

According to a medical study, 15% of people will experience an adverse side effect

have adverse side effect?
A)O 0.594
B)0.646
C)0.736
D)0.264

Answers

Answer:

c

Step-by-step explanation: trust me

The probability that the people that would have adverse effect are at most 2 is 0.736

What is probability?

This is the theory that is used in statistics to explain the chances of an event occuring.

To solve for the probability of at most 2, we solve for 1-  P(1) + P(2)

= 1/12 + 2/12

= 1 - 0.083+0.167

= 0.73

Therefore the probability that the most people with adverse effect is 2 is 0.736. Option c is correct.

Answer:

Refer to image

Step-by-step explanation:

When creating a histogram it is best to create a range for the different variables that are available.

So for the sake of covering all the possible ranges from 1 - 22, let's divide it into 5 categories.

0 - 5        

6 - 10  

11 - 15

16 - 20

21 - 25

Now that we have set ranges for the different variables, we then find the frequencies.

0 - 5  : 3      

6 - 10 : 2

11 - 15 : 3

16 - 20 : 1

21 - 25 : 3

Now that we have all the values we can then create our histogram
