Answer:

I believe it would be cpctc

Step-by-step explanation:

It would be that due to the fact it is not talking about an angle so therefore it wouldn't be ASA, it also wouldn't be definition of congruent segments because that is represented using segments and as you can see it has no tick marks, which need to be seen for the definition of congruent segments. CPCTC would be correct because it stands for corresponding parts of congruent triangles are congruent and can be represented in both lines and angles, and the problem is asking about lines and how you know they are congruent.

Answer:

Step-by-step explanation:

i am unsure of what you actually need, but i want to help you.

if you were to set the boundaries of the feasibility region it would be as follows:

as points

A(1, 17/3) B(7, 11/3) C(7, infinity) D(1, infinity)

as graphs

y=-1/3x+6 where 1≤x≤7

x=1

Suppose that salaries for recent graduates of one university have a mean of $25,700 with a standard deviation of $1350. Using Ch

sergeinik [125]

Answer:

75% of the data will reside in the range 23000 to 28400.

Step-by-step explanation :

To find the range of values :

We need to find the values that deviate from the mean. Since we want at least 75% of the data to reside between the range therefore we have,

$1 - \frac{1}{k^2} =\frac{75}{100}$

Solving this, we would get k = 2 which shows the value one needs to find lies outside the range.

Range is given by : mean +/- (z score) × (value of a standard deviation)

⇒ Range : 25700 +/- 2 × 1350

⇒ Range : (25700 - 2700) to (25700 + 2700)

Hence, 75% of the data will reside in the range 23000 to 28400.

Please give the right answer and show work if possible

balandron [24]

Answer:

B

Step-by-step explanation:

Sin 64=23/a. Let use trig identities to find other points

First, since sin and cos like are complementary angles we can use this formula

$\sin(x) = \cos(y) \: \: \: x + y = 90$

sin 64=23/a

$64 + x = 90$

$x = 26$

So cos 26=sin 64 so B is a answer

Solve this system by elimination 5x=y+6;5x+2y=3

Licemer1 [7]

Answer:

5x-6=y

5x+2(5x-6)=3
5x+10x-12=3
15x=15
x=1

Now

5(1)-6=y
-1=y
