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.

Answer:

y= (-1/2)x+1

Step-by-step explanation:

The general equation of a line in the slope intercept form is y= mx+b, where

m = the slope, and b = y-intercept (where the line crosses the y-axis)

for points (x1 = -6, y1 = 3) and (x2 = -2, y2 = 1)

m= (y2-y1)/ (x2-x1) = (1 - 3)/ (-2 - -6) = -2 / 4 = -1/2

the equation is now y= (-1/2)x+b

substitute the x and y coordinates of any of the points in the equation

for point (-2, 1) we will have  1 = (-1/2)(-2)+b, so b=1

The equation in slope intercept form that contains the points (-6,3) and

(-2,1) is y = (-1/2)x+1

Answer:

$340.00

Step-by-step explanation:

What I like to do first is find 10% of the number.

So 10% of 400 would be $40.

Then find half (5%) of the 10% ($40), which would be $20.

Add the $40 + $20 to get $60.

Then take $400 and subtract $60,

which gives you $340.00

Answer:

20a^3 b^8

Step-by-step explanation:

( 5a^2b^3 ) ( 4ab^5 )

= ( 5 . a^2 . b^3 ) ( 4 . a . b^5 )

= ( 5 . 4 ) ( a^2 . a ) ( b^3 . b^5 )

= 20 ( a^2 . a^1 ) ( b^3 . b^5 )

= 20 ( a^( 2 + 1 ) ) ( b^( 3 + 5 ) )

= 20 ( a^3 ) ( b^8 )

= 20a^3 b^8

Answer:

140

Step-by-step explanation:

Answer:

E

Step-by-step explanation:

Answer:

30$

Step-by-step explanation:

lets assume you didn't have a coupon then the total bill would have been 120$

so for 4 friends including u the bill would have been 120$

: 4 friends = 120 $

for : 1 friend = x$

cross multiply

4x = 120 × 1

4x =120

divide both sides by the coefficient of x

x =120 \ 4

x = 30$

therefore: 1 friend = 30$

Answer:

B

Step-by-step explanation:

A: Also could be written as 0-5: its a division.

B: Also could be written as -1(5+5). The final answer is -10 and its an addition of 5 and 5.

C: Its a multiplication

D: Similar to B, it could be written as 5-5=0. Its a division of 5 and 5.

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.

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.

Scientific Notation is the way of writing a number or expressing them in a shorter or more compact way.

No, Taylor's resoning is incorrect because  2,800,000 = [tex]2.8 * 10^{6}[/tex]

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is  [tex]2.8 * 10^{6}[/tex].  

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, Taylor's reasoning is incorrect.
