Answer:

= 150°

Step-by-step explanation:

Since the polygons are regular, certain mathematical assumptions would help us here.

A square is a quadrilateral with all it's 4 sides equal and all it's angles equal.

Sum of angles of a regular quadrilateral = 360.

Therefore, a single angle = 360/4

= 90°.

The Triangle is adjacent to the side of the square. We will thus assume it's an Equilateral triangle.

For an equilateral triangle, all it's 3 angles = 180.

A single angle = 180/3

= 60°.

With this,

Angle ABC = 90° + 60=

= 150°

Martin's running ability is measured by this proportion:
jek_recluse [69]

Answer:

A = 13 B =0 = 1/2   This way x in a graph can be his start running ability (time) each A value applied will divide by 1/2 to make 6.5 and when x = 21 then y can be 7 with the AB equation above as 13 x 1/2 = 6.5. add multiple 0 doesn't occur because we start with x value 21 to show the starting value. Alternately x= 137 and y = 0. Then the graph can go up or down when his running value changes as a negative decrease 137 - b = -? and a positive increase will show increase 137+b = +?.

Peter wants to test an assumption on the number of trees that tested positive for a particular infestation. He decides to focus
LUCKY_DIMON [66]

Answer:

H0 : P ≤ 0.12

H1 : P > 0.12

Step-by-step explanation:

12% = 12/ 100 = 0.12

Given the population proportion, P = 0.12

The claim is the alternative hypothesis, H1 ; which is to test if more than 12% of trees have been infested.

Hence, the alternative hypothesis will be ;

H1 : P > 0.12

The null hypothesis which is the initial truth is always the opposite of the alternative hypothesis, Therefore, we write our null as ;

The null hypothesis ; H0 : P ≤ 0.12

Therefore, we have :

H0 : P ≤ 0.12

H1 : P > 0.12

6.) Alan, Becky, Jesus, and Mariah are four students in the chess club. If two of these students will be selected to represent t
Artist 52 [7]

Let's begin by listing out the information given to us:

There are four students: n = 4

Number of students to be selected: r = 2

To calculate the combination of 2 students to be chosen, we use:

\begin{gathered} ^4C_2=\frac{n!}{(n-r)!}=\frac{4!}{(4-2)!}=\frac{4!}{2!} \\ ^4C_2=\frac{4\cdot3\cdot2\cdot1}{2\cdot1}=\frac{4\cdot3}{1}=12 \\ ^4C_2=12 \end{gathered}

Therefore, there 12 possible combinations from these

3³+1x9+12 answer please, I really think it's 48.
UNO [17]

Answer:

You are correct the answer is 48.

Step-by-step explanation:

To begin solving this question you would want to start simplifying it to make it more understandable.

3^3 is 27 which now gives you 27 + 1 x 9 +12 which makes it easier to solve.

Then you would take 1 x 9 = 9 (multiply left to right)

Now it is simple addition

27 + 9 + 12 = 48

Hopefully this helps.
