An educational researcher devised a wooden toy assembly project to test learning in 6-year-olds. The time in seconds to assemble the project was noted, and the toy was disassembled out of the child's sight. Then the child was given the task to repeat.

The differences are: -9, 22, 0, -19, -105, 24, -46, -8, -5, -8, -8
The mean of the differences is: -9.5
The standard deviation of the differences is: 38.3
To calculate the 99% confidence interval, we use the formula:
(mean difference) +/- (t-value) * (standard deviation of differences / square root of sample size)
The sample size is 11, so the degrees of freedom are 10. Using a t-table with 10 degrees of freedom and a 99% confidence level, we find the t-value to be 3.169.
Plugging in the values, we get:
-9.5 +/- 3.169 * (38.3 / sqrt(11))
Which simplifies to:
-9.5 +/- 23.5
Therefore, the 99% confidence interval for the difference in means is (-33, 14).

Answers
Answer:
58°Step-by-step explanation:
We will use the tangent function since we know the opposite and adjacent sides.
Tangent = opposite/adjacent
Tan(e) = 16/10
Tan(e) = 1.6
Use the inverse tangent function to find the angle.
Arctan (1.6) = 57.9946168
Rounding this we get: 58°
Answer:
\(\boxed {\boxed {\sf 58 \textdegree}}\)
Step-by-step explanation:
The three trigonometric ratios (Soh- Cah- Toa) are:
sin(θ) = opposite/hypotenuse cos(θ)= adjacent/hypotenuse tan(θ)=opposite/adjacentWe want to find the indicated angle. We have the opposite side (16) and the adjacent (10). Therefore, we must use tangent.
\(tan(\theta)= \frac{opposite}{adjacent}\)
\(tan(\theta)=\frac{16}{10}\)
To find an angle measure, the inverse tangent must be used.
\(\theta= tan^{-1} (\frac{16}{10})\)
Type the right side into a calculator.
\(\theta=57.99461679\)
If this is rounded to the nearest whole number, the 9 in the tenth place tells us to round the 7 up to a 8.
\(\theta \approx 58\)
The angle is about 58 degrees.

which must be true in order for the relationship zyx~wvu to be correct
Answers
In order for the relationship zyx ~ wvu to be correct, the following conditions must be true:
Corresponding angles are congruent: The angles formed by matching vertices should have the same measures in both triangles. This ensures that the corresponding angles are equivalent.
Corresponding sides are proportional: The lengths of the sides that connect the corresponding vertices of the triangles should have a consistent ratio. This implies that the corresponding sides are proportional to each other.
These conditions are based on the definition of similarity between two triangles. If both the corresponding angles are congruent and the corresponding sides are proportional, then the triangles zyx and wvu are considered similar (denoted by ~).
Therefore, in order for zyx ~ wvu to be correct, the congruence of corresponding angles and the proportionality of corresponding sides must hold true.

After training Naruto went to a ramen shop for dinner. Since Naruto eats ramen for lunch and dinner daily, the shopkeeper gives him a 33.33% discount. If ramen costs 45 cents, how much does Naruto spend in 15 days?
Points given: 20
Answers
To calculate how much Naruto spends on ramen in 15 days, we need to determine the total cost of ramen per day and then multiply it by 15.
Since Naruto receives a 33.33% discount, he pays 100% - 33.33% = 66.67% of the original price.
66.67% of 45 cents is (66.67/100) * 45 = 30 cents.
So, Naruto spends 30 cents on ramen per day.
To find out how much he spends in 15 days, we multiply the daily cost by the number of days:
30 cents * 15 = 450 cents.
Therefore, Naruto spends 450 cents, which is equivalent to $4.50, on ramen in 15 days.

Elizabeth claims that the only square root of 36 is 6. Which statement below disproves Elizabeth’s claim? A) 6 is a factor of 36. B )36 has both even and odd factors. C) The square root of a whole number is sometimes a decimal value. D) The square root of a positive number can be a negative or positive value.
Answers
Answer:
D) The square root of a positive number can be a negative or positive value.
Step-by-step explanation:
36 is a perfect square, meaning that the square root of 36 is equivalent to an integer, 6, whereby, the integer 6, when multiplied by itself gives us the perfect square, 36.
i.e. 36 = 6*6 = 6²
√36 = √6² = 6
There are actually two possible square root of 36. That is -6.
Square of, -6², equivalently is -6 * -6 = 36.
Therefore, √36 = ±6.
So, her claim is wrong. 6 is not the only square root of 36.
Square root of 36 could be negative 6 or positive 6.
which of the binomials below is a factor of this trinomial
x^2-13x+30
Answers
The binomials (x - 3) and (x - 10) are factors of the trinomial x² - 13x + 30.
To determine which binomial is a factor of the trinomial x² - 13x + 30, we need to factorize the trinomial completely.
In this case, we need to find two binomials in the form (x - a)(x - b) that satisfy the equation:
(x - a)(x - b) = x² - 13x + 30
So, (x - 3)(x - 10) = x² - 13x + 30.
Therefore, the binomials (x - 3) and (x - 10) are factors of the trinomial x² - 13x + 30.

which grows at the fastest rate for increasing values of x
\(f(x)=4*2^x\\h(x)=9x^2+25\\\\g(x)=15x+6\)
Answers
The function that grows at the fastest rate for increasing values of x is f(x) = 4×2ˣ.
We can see this by comparing the growth rates of the three functions for larger and larger values of x.
As x gets larger, the exponential function f(x) grows much faster than the other two functions, which are both polynomial functions.
if we plug in x = 10, we get:
f(10) = 4×2¹⁰ = 4×1024 = 4096
h(10) = 9×10² + 25 = 925
g(10) = 15×10 + 6 = 156
As we can see, f(10) is much larger than h(10) and g(10), indicating that f(x) grows at a much faster rate than the other two functions.

Answer:
The given quadratic equation is: 10x^2 + 7x + 3 = 0.
To solve this quadratic equation, we can use the quadratic formula:
x = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = 10, b = 7, and c = 3.
Substituting these values into the formula, we get:
x = (-7 ± sqrt(7^2 - 4(10)(3))) / 2(10)
x = (-7 ± sqrt(49 - 120)) / 20
x = (-7 ± sqrt(-71)) / 20
Since the square root of a negative number is not a real number, this quadratic equation does not have any real solutions. Therefore, none of the options (A), (B), (C), or (D) are correct.
