Answers

Answer 1

Answer:

a x=-3

Answers

Answer:

[tex]x>17[/tex]

Step-by-step explanation:

We can treat an inequality just the same as an equality in terms of manipulation!(This doesn't hold for multiplying or dividing by negative numbers, but it holds for all addition).

So, we can add [tex]7[/tex] to both sides of the inequality to get [tex]x-7+7>10+7[/tex].

We can simplify [tex]-7+7[/tex] into [tex]0[/tex], and [tex]10+7[/tex] into [tex]17[/tex].

So, the answer is [tex]\boxed{x>17}[/tex] and we're done!

What is the value of T in this exterior angle

Answers

Answer:

t =30

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles.

t + (2t-28) = t+32

Combine like terms

3t -28 = t+32

Subtract t from each side

3t -28-t = t+32-t

2t -28 = 32

Add 28 to each side

2t-28+28 = 32+28

2t = 60

Divide by 2

2t/2 = 60/2

t =30

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

Exterior Angle of a triangle is equal to the sum of two opposite interior angles of the same triangle, so

[tex]t + 32 = t + 2t - 28[/tex]

[tex]t + 32 = 3t - 28[/tex]

[tex]3t - t = 32 + 28[/tex]

Answer: C) 8

Explanation: It seems that the first three shapes in this pattern are increasing by one side as they progress, that means they go 3 sides, 4 sides, 5 sides, etc. If this keeps going until the 6th shape, it would land on 8 sides, which is an octagon.

Dr. Reyes is examining whether exercise is linked to mood. She recruits a sample of college students and asks them to answer whether they exercised at least three times last week (yes or no) and to rate their mood in the last week (1: Not happy at all to 5: Very happy). Her results show that students who exercised in the last week also reported happier moods. Can Dr. Reyes make a causal inference from her study

Answers

The answer to whether Dr. Reyes can make a causal inference from the study is;

No, she can't make a casual inference from the study because she met only one of the three criteria's for causality.

To answer this question, we need to know the conditions for causality in statistics research because causality gives the relationships such that a change in one variable would have to result in a change in another variable.

Now, the three conditions are;

1) Covariation; This condition means that the causal variable must have to vary with with the variable it is assumed to cause in a systematic manner.

2) Temporal precedence; Thus condition simply means that cause must precede effect. In summary it denotes that the variable that has the causal effect must come before the effect that it is meant to cause.

3) Control for extraneous variables; This condition means that results of an experiment or research must not be due to factors outside of the experiment/research

     Now, in our question, he fulfilled the covariation condition because the

result of the research is tied to the responses from the sample students.

However, she did not fulfill the temporal precedence because the cause of

their moods did not precede the effects in his research.

Also, she did not fulfill the condition of control of extraneous variables

because other factors outside of the research itself may have affected their

moods.

Answers

Given equation of the line ,

[tex]\implies 4x - 5y - 1 = 0 [/tex]

Transpose terms to RHS ,

[tex]\implies 5y = 4x - 1 [/tex]

Divide both sides by 5 ,

[tex]\implies \boxed{ y =\dfrac{4}{5}x -\dfrac{1}{5}}[/tex]

x=27

Step-by-step explanation:

Aight so the angle of line AB equals 180 degrees. You have 36 degrees plus the right angle (90 degrees) which gets you 126 degrees. Subtract 126 from 180 and you get 54, the remaining value. So if 2x=54, then divide both sides by 2 to get x=27. that should be it
