Answer:
How many brothers and sisters do people in our class have?
Students might suggest that we can ask how many siblings, or they might suggest we ask how many brothers, how many sisters and how many altogether.
The idea of asking about brothers and sisters separately allows for a deeper exploration of the data and a more in depth answer to our investigative question.

ebrant spends $76 in a gift shop. This is 80% of the money he planned to
spend in the gift shop. How much money, in dollars, did Mr. Hildebrant plan to
spend in the gift shop?
Answer:
Mr. Hildebrant planned to spend $95 in the gift shop.
Step-by-step explanation:
We want to find 80% of $? equals $76.
We can write an equation to help us solve for x, the money that Mr. Hildebrant planned to spend in the gift shop.
.80x = 76Divide both sides of the equation by .80.
x = 95Mr. Hildebrant planned to spend $95 in the gift shop.

Select the FALSE statement about completely random design. a.) Subjects are randomly assigned to treatments. b.) Any number of treatments may be addressed. c.) The additional variables affect different control groups differently. d.) It minimizes the effects of confounding variables.
Answer:
your answer is A.
Step-by-step explanation:
The false statement about completely random designs is this: c.) The additional variables affect different control groups differently.
What is the false statement?The false statement about completely random designs is that additional variables affect different control groups differently. It is however true that in completely random esigns, the subjects are randomly assigned to treatments and any number of treatments may be addressed.
Also, the goal of this type of design is to reduce the effects of confounding variables. So, the correct option number that describes the false statement is C.

The diameter of a circle is 100 cm. What is the circumference of the circle? (Use 3. 14 for π. )
Explanation:
Use the formula C = pi*d
We're multiplying 3.14 by the diameter 100 to get 314, which is the approximate distance around the circle (aka perimeter). The value is approximate because pi = 3.14 is approximate.

find the surface area 10.2 mi 14 mi
Answer:
The surface area = 320.442450666159 mi²Step-by-step explanation:
Formula : ( surface area of a cone )_________________________
The total surface area = The curved surface area + area of the base
____________________________________________________
→The curved surface area = π × r × g = π × r × (√(h2 + r2))
where g is the slant height of the cone and r is the radius of the base
and h is the height of the cone
and g = √(h2 + r2)
→Area of the base = π × r²
We get :
The curved surface area = π × r × (√(h2 + r2))
= π × 5.1 × √(14^2+(5.1)^2)
= 238.729625746288
Area of the base = π × r²
= π × (5.1)^2
= 81.712824919871
Conclusion:
The total surface area = The curved surface area + area of the base
= 238.729625746288 + 81.712824919871
= 320.442450666159

Optimize the equation P = 3x + y using the constraints
x ≥ 0, x ≤ 4, y ≥-1 and y ≤ 5.
What is the maximum?
Answer:
P = 17
Step-by-step explanation:
let's separate this into x and y components
x component: 3x
as x increases, so does the x component. e.g. 0 * 3 = 0, 4 * 3 = 12. therefore, we want x as high as possible
y component: y
as y increases, so does the y component. this is because the y component is literally just y.
therefore, given these two, to maximize P, we want x and y to be as high as possible
in 0 ≤ x ≤ 4, the maximum of x is 4
in -1 ≤ y ≤ 5, the maximum of y is 5
plug these in to get
3(4) + 5 = 17 as our answer

15) A, B, C, D, E and F are towns situated as follows. * A is 30 km east of D * C is 20 km east of E * F is 10 km west of B * D is 10 km south of F * A is 10 km north of C How far would you need to travel to get from B to E?
Answer:
Option D: 20km South
Step-by-step explanation:
Lets say A = (0, 0)
Finding B:A is 30km East of D which makes D = (-30, 0)
D is 10km South of F which makes F = (-30, 10)
F is 10km West of B which makes B = (-20, 10)
Finding E:A is 10km North of C which makes C = (0, -10)
C is 20km East of E which makes E = (-20, -10)
Finding the answer:Find distance from B = (-20, 10) to E = (-20, -10)
1. Cancel equivalent values:
x of B = (-20) and x of E = (-20)
Remove x from equation.
2. Solve for answer:
B = 10 and E = (-10)
Find the difference: (-10) - 10 = (-20)
Conclusion:
South translates to negative on a graph making the answer 20km South

The value that can take the place of "?" is -6a. The length of line AB is 6a units.
What is the length of any line on the graph?The distance or length of any line on the graph,
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
where,
d = distance/length of the line between point 1 and 2,
(x₁ , y₁) = coordinate of point 1,
(x₂ , y₂) = coordinate of point 2,
The length of a line with two points known is written as,
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given the coordinate of points A and B are (-3a,b) and (-3a,b), respectively. Therefore, the length of the line AB can be written as,
[tex]AB = \sqrt{(-3a-3a)^2+(b-b)^2}\\\\AB = \sqrt{(-6a)^2+(0)^2}\\\\AB = 6a[/tex]
Hence, the length of line AB is 6a units.
