Alia and her husband have a list of six names for their new baby boy. Each name is equally likely to be picked. They make the table to assign each name a number, then they roll a die 150 times. The results are in the table. Select all the true statements.
Answers
Answer:
3 and 4 are the only true statements.
Step-by-step explanation:
1 is incorrect because the experimental probability is calculated by dividing 24 by 150, which gives us 0.16 or 16%, not 0.15 or 15%.
2 is wrong because 6 ÷ 150= 0.04, giving each number a 4% chance of occurrence.
3 is correct because Karl occurs 28 of the 150 times. 28 ÷ 150= 0.1866666666666667, which is 18.66666666666667%, or about 19%.
4 is also correct because the theoretical probability of each name is 25.
5 is false because the experimental probability of Martin, Paxton, and Sal were less than the theoretical probability.
Triangle JKL was dilated with the origin as the center of dilation to create triangle J'K'L'. The triangle was dilated using a scale factor of 1/2. The coordinates of the vertices of triangle JKL are given. You can use the scale factor to find the coordinates of the dilated image. Enter the coordinates of the vertices of triangle J'K'L' below.
(Decimal values may be used.)
Answers
Answer:
J' (-2, 2.5), K' (1, 2.5) L' (1, -2.75)
Step-by-step explanation:
With a scale factor of 1/2=.5 you can simply multiply all coordinates by .5 (or divide by 2)
J (-4,5) x 1/2= (-2, 2.5)
K (2,5) x . 5 = (1, 2.5)
L (2, -5.5) /2= (1, 2.75)

Two friends plant a tree and record the height of the tree each following year to track its growth. The data can be represented by the linear model y = 4.3z +3.25, where y represents the height of the tree, in feet, and z represents the number of years since it was planted.
Based on the linear model, what is the expected height of the tree in 8 years?
3.25
4.3
31.2
37.65
Answers
Answer:
D.) 37.65
Step-by-step explanation:
I know that 8 is an input based on this word problem. So, then I plug in the 8 for z and solve to find the expected height of the tree in 8 years.
y=4.3z+3.25
y=4.3(8)+3.25
y=34.4+3.25
y=37.65
In 8 years the expected height of the tree is 37.65

Answers
Answer:
40 in.²
Step-by-step explanation:
First, you have to find the area of the triangle, which you then multiply by 4 (because there are 4 triangles):
A=1/2(bh)
A=1/2(3x4)
A=1/2(12)
A=6
6x4=24 in.²
Next, you have to find the area of the square:
A=bh
A=4x4
A=16
Now, add 24 and 16 together to get your answer of 40 in.².

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.
Answers
Answer:
The total area of the back classroom wall is (20ft x 12ft) = 240ft²
The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².
Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.
Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.
How can I find the cube root of 64?
Answers
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Step-by-step explanation:
√((1 + sin x) / (1 − sin x)) + √((1 − sin x) / (1 + sin x))
Square and take the square root.
√[√((1 + sin x) / (1 − sin x)) + √((1 − sin x) / (1 + sin x))]²
√[(1 + sin x) / (1 − sin x) + 2 + (1 − sin x) / (1 + sin x)]
Add the fractions using least common denominator.
√[((1 + sin x)² + (1 − sin x)²) / (1 − sin²x) + 2]
√[(1 + 2 sin x + sin²x + 1 − 2 sin x + sin²x) / (1 − sin²x) + 2]
√[(2 + 2 sin²x) / (1 − sin²x) + 2]
Use Pythagorean identity:
√[(2 + 2 sin²x) / (cos²x) + 2]
√[2 sec²x + 2 tan²x + 2]
√[2 sec²x + 2 (tan²x + 1)]
Use Pythagorean identity:

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Step-by-step explanation:
on Monday she reads 3/8 of the novel which means
x 352 = 132 pages
on Tuesday she reads 28 pages, doesn't require any calculations.
on Wednesday she reads 1/4 of the novel,

Recent statistics have reported that the total area of Brazil is about 3 × 10^6 square miles, while the total area of Japan is about 2 × 10^5 square miles.
Create and solve an equation that can be used to find about how many times larger the area of Brazil is than the area of Japan.
Answers
Answer:
195500000
Step-by-step explanation:
Population density
Population density of Brazil and Peru are equal
Thus,
Total population of any area million square kilometer people per square kilometer
miilion
Brazils area = 3 x 10^6 = 3000000 square miles
Japans area = 2 x 10^5 = 200000 square miles
Now we can divide Brazils area by Japans area, to find out how many times bigger Brazil is than Japan:
3000000 / 20000 = 15
Brazil is 15 times larger than Japan.
