Answer:
B. 40%Step-by-step explanation:
We can count two heads out of 3 coin tosses, this is 10 out of 25:
P(HH) = 10/25 = 40/100 = 40%The experimental probability of getting exactly 2 heads out of 3 coin tosses is 40% option second is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The total outcome set
T = {HTT, HHH, HTH, THT, THH, THT, THH, THT, HHT, TTH, HHH, TTT, HHT, THH, HTT, HHH, THT, HTT, HHT, HTH, THH, HTT, THH, TTH, HTT}
n(T) = 25
Total favourable outcome n(E) = 10
The probability = 10/25 = 0.4
= 0.4×100 = 40%
Thus, the experimental probability of getting exactly 2 heads out of 3 coin tosses is 40% option second is correct.

Answer:
127
Step-by-step explanation:
The sum of 7 terms of the series 1 +2 +4 +... with first term 1 and common ratio 2 is given by ...
Sn = a1 × (r^n -1)/(r -1) . . . . . . first term a1, common ratio r
S7 = 1 × (2^7 -1)/(2 -1) = (128 -1)/1 = 127

Answer:
Area is 220 cm²
Step-by-step explanation:
Firstly divide the polygon into rectangle and triangle
For rectangle area
Area = A = L × W = 11 × 18 = 198 cm²
For triangle
Area = A = 1/2 bh = 1/2 × (15-11) × (18-7) = 1/2 × 4 ×11 = 44/2 = 22 cm²
Add them
198 + 22 = 220cm²

Determine the area of the composite figure.
Answer:
Area = 142.5 square inches
Step-by-step explanation:
So your shape is kind of a little house. The bottom part is a rectangle 9 × 9.5. The area of the rectangle is
Area = length×width
= 9 × 9.5
= 85.5
The "roof" of the little house is a triangle. The area of a triangle is 1/2×base×height
Now, the base of the "roof" is the same as the floor of the house, 9.5 inches.
The height of the whole thing is 21 inches. If we take away the rectangle's wall-height, we'll get the height of the "roof".
Roof height= 21 - 9
= 12 inches
Area_roof
=1/2 × base × height
=1/2 × 9.5 × 12
= 57 square inches
Total area is bottom plus roof (the rectangle and the triangle)
Total Area
= 85.5 + 57
= 142.5 sq in
Which expressions are equivalent to 4d+6+2d
(Choice A) 2(3d+3)
(Choice B) 6(d+6)
(Choice C) (3d+3)+(3d+3)
Answer:
(Choice A) 2(3d+3) & (Choice C) (3d+3)+(3d+3)
Step-by-step explanation:
[tex]4D + 6 + 2D = 6D + 6 = 2(3D + 3)[/tex] <--- A is correct
[tex]4D + 6 + 2D = 6D + 6 = 6(D +1)[/tex] < --- B is NOT correct
[tex]4D + 6 + 2D = 6D + 6 = 3d + 3d + 3 + 3 = (3d + 3)+(3d +3)[/tex] by associative and commutative properties
so C is correct
A and C are both correct.
Answer:
Choices A and C
Step-by-step explanation:
Start by simplifying the original expression.
4d+6+2d
Combine like terms
6d+6
Now, we can check each expression to see if it is equivalent to 6d+6
Choice A:
2(3d+3)
Distribute the 2
2(3d)+2(3)
6d+6 --> It is equivalent!
Choice B:
6(d+6)
Distribute the 6
6(d)+6(6)
6d+36 --> No, it is not equivalent
Choice C
(3d+3)+(3d+3)
The parentheses aren't necessary so we can take them out.
3d+3+3d+3
Combine like terms
6d+6 --> It is equivalent!

A researcher measures the amount of food consumed by each dog in her lab. She finds that the mean amount eaten by the 10 dogs is 14 oz. The sum of squared deviations is 220. What is the variance for this data set
Using statistical concepts, it is found that the variance for this data set is of 22 oz squared.
What are the mean and the variance of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The variance of a data-set is given by the sum of the differences squared between each observation and the mean, divided by the number of values.
From the second bullet point, the variance can also be interpreted as the sum of squared deviations divided by the sample size.
In this problem, the sum of squared deviations is 220 and the sample size is 10, hence, the variance for this data set is of 22 oz squared.

In a race you walked 9 5/6 miles and ran 1 1/3 miles.
How much further did you walk than run?
Do not reduce your answer to lowest terms.
Answer:
23/6 or 3 5/6
Step-by-step explanation:
Well, here you just have to subtract and think about the question.
Walk = 9 5/6
Run = 1 1/3
9 5/6 - 1 1 /3 = 23/6
23/6 = 3 5/6
Use intercepts to graph the linear equation -4x+3y=-30 .
Answer:
See below
Step-by-step explanation:
Y-intercept
-4x + 3y = -30
-4(0) + 3y = -30
3y = -30
y = -10
(0, -10)
X-intercept
-4x + 3y = -30
-4x + 3(0) = -30
-4x = -30
x = 15/2
x = 7.5
(7.5,0)
After plotting the intercepts, connect them with a line to get your equation

Answer:
4. m<3 = 120
5. m<4 = 13
6. m<2 = 70
7. m<1 = 115
Step-by-step explanation:
4. m<3 = 120, this is because it is the same as m<1 due to vertical (congruent) angles
5. m<4 = 13, this is because it is the same as m<2 due to vertical (congruent) angles
6. m<2 = 70, this is because m<2 and m<3 are supplementary (adding up to 180) so we would subtract 180 - 110 (aka m<3) = 70 (aka m<2)
7. m<1 = 115, this is because m<1 and m<4 are supplementary (adding up to 180) so we would subtract 180 - 65 (aka m<4) = 115 (aka m<1)
