Forty infants are being studied to test the effectiveness of diaper capacity on four types of diapers: ABC, and D The researcher calculates diaper's actual capacity compared with its listed capacity. The response variable is the amount of capacity after one hour of treatment. Previous studies have shown the may vary based on subject's activity levelHow should the subjects be blocked? Explain
Answer: They should be blocked by activity level so the subjects are as similar as possible.
Step-by-step explanation:
Blocking is used to account for suspected differences in experimental units or subjects. In this case, the study wanted to take into account the difference in activity levels, which can affect the diaper's capacity as described in the paragraph.

Marshall knows that he burns 235 calories by walking for 30 minutes. This week, Marshall walked for 360 minutes. How many calories did Marshall burn by walking this week?
Answer:
2820 calories
Step-by-step explanation:
Since 30 can fit into 360, you can divide it.
360/30=12
12 is what you will multiply to the number of calories in 30 minutes.
235*12=2820
use a number line to find the difference-6.5 - 2
Answer:
The answer would be -8.5
Step-by-step explanation:
If you start at -6.5, to find the difference (subtract) you would move left two whole spaces to get to -8.5.
On the other hand, if you were to start at 6.5 and subtract 2, your answer would be 4.5.
It depends if your first number is negative or positive.

To quickly find the product of a whole number time 1000, add *Blank* Zeroes to the number
Answer:
Add three zeros to the end.
Step-by-step explanation:
When you add three zeros, the result is equivalent to when multiplying by 1000. For example, 20 times 1000 is 20,000.
Hi! I believe your answer is 3 zeros. For example, 7 × 1,000 = 7,000 (add 3 zeros). I hope this helps you! Good luck and have a great day/night. ❤️✨

In isosceles triangle DAC, AD is congruent to AC. Kiran knows that the base angles of an isosceles triangle are congruent. What additional
information does Kiran need to know in order to show that AB is a perpendicular bisector of segment CD?
A perpendicular bisector is a line that crosses (bisects) another line segment at 90 degrees, dividing the line segment it crosses into two equal length lines
The additional information Kiran need to know to show that AB is a perpendicular bisector is the fourth option;
DB and BC are congruent
The reason for the above selection is as follows:
The information about the isosceles triangle DAC Kiran knows are;
Triangle DAC = An isosceles triangle
Segment AD is congruent to segment AC
Segment AB is a is a line from the vertex point A to the side CD of triangle DAC
The required parameter:
The information Kiran has know so as to show that AB is a perpendicular bisector of CD
Method:
Determine an attribute present in triangle DAC with line AB drawn that is due to line AB being a perpendicular bisector
Solution:
For AB to be a perpendicular bisector, then DB and BC are congruent
Given that DB and BC are congruent, we get;
AB is congruent to AB by reflexive property
Therefore, given that AD is congruent to AC, we have;
Sides AD, AB, and DB in triangle ΔADB are congruent to the corresponding sides AC, BC, and AB in triangle ΔACB, which gives
ΔADB is congruent to ΔACB by Side-Side-Side, SSS, congruency rule
Therefore, ∠ABD ≅ ∠ABC, by Congruent Parts of Congruent Triangles are Congruent, CPCTC
∠ABD = ∠ABC by definition of congruency
∠ABD and ∠ABC are linear pair angles, therefore;
∠ABD + ∠ABC = 180°
∠ABD + ∠ABD = 2 × ∠ABD = 180° by substitution property
∠ABD = 180°/2 = 90°
∠ABD = 90° = ∠ABC, therefore, AB is perpendicular to CD and AB is a perpendicular bisector of CD
Therefore, the correct option Kiran need to know in order to show that AB is a perpendicular bisector of segment CD is the option; DB and BC are congruent

Nicole wants to buy a charm bracelet. Summerfield Fine Jewelry charges $26 per charm, plus $19 for the bracelet. Flynn Jewelers, in contrast, charges $27 per charm and $11 for the bracelet. If Nicole wants to add a certain number of charms to her bracelet, the cost will be the same at either jewelry shop. How many charms would that be? What would the total cost of the bracelet be?
Answer:
There are 8 number of charms
Total cost = $227
Step-by-step explanation:
Let
Number of charms = c
Summerfield Fine Jewelry charges $26 per charm, plus $19 for the bracelet.
26c + 19
Flynn Jewelers charges $27 per charm and $11 for the bracelet
27c + 11
How many charms would that be ?
Equate the cost at both jewelry shop
26c + 19 = 27c + 11
Collect like terms
26c - 27c = 11 - 19
-c = - 8
c = 8
There are 8 number of charms
What would the total cost of the bracelet be?
Using any of the jewelry shop cost
Flynn Jewelers cost
= 27c + 11
= 27(8) + 11
= 216 + 11
= 227
Total cost = $227

Anyone know how to do this??
Answer:
x = 60
Step-by-step explanation:
In order to make L parallel (||) to M, you want to prove that the angles are same-side interior angles since the Same-Side Interior Angle Theorem only works for parallel lines cut by a transversal.
In order to make the angles (marked with the expressions) same-side interior angles, they have to add up to 180 degrees because they are supplementary angles.
Make an equation where the two angles add up to (equal) 180.
(x - 5) + (2x + 5) = 180Combine like terms on the left side of the equation.
3x = 180Divide both sides of the equation by 3.
x = 6060 is the value of x that will make L || M.
Which has a greater slope, a horizontal line or a vertical line?
Answer:
A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).
Answer:
A horizontal line has a greater slope than a vertical line

Which equation does not represent a function? Why? A) y = x2; There are two outputs for each input. B) y2 = 4x; There are two outputs for each input. C) y = x; The output value is the same as the input value. D) y = −x; The output value is the opposite of the input value.
Answer:
B) y² = 4x; There are two outputs for each input
Step-by-step explanation:
For an equation to be called a function, the input values for x must only result in a single output for y.
Based on this definition if a function, the functions y = x², y = -x and y = x are all functions because for any value of x imputed in them, we can only get one equivalent value of y.
The only exception is the function y²= 4x
For this function, for any value of x, there will be more than one output for y. Take x = 1 for example
y² = 4(1)
y² = 4
y = ±√4
y = ±2
This shows that y = 2 and -2
Also if x = 4
y² = 4(4)
y² = 16
y = ±√16
y = ±4
y = 4 and -4
No matter the value of x imputed, the output value y will always be two (a positive and a negative value)
Hence, option B is correct.
Answer:
B
