The most appropriate statistical test is a two-way ANOVA

From the question, we have the following parameters that can be used in our computation:

Question: Is there a difference in mean height between middle school students based on gender (male and female) and grade (6th, 7th, 8th)?

The most appropriate test is the two-way ANOVA

This is so because the test is a type of hypothesis test that uses a statistical model to analyze the variance between groups and within groups.

It tests the null hypothesis that the means of all groups are equal against the alternative hypothesis that at least one group mean is different from the others.

In this case, the groups are

The statement "an exterior angle of a triangle will always be obtuse" is actually false.

Why it is?

An exterior angle of a triangle is formed by extending one of the sides of the triangle, and it is the angle between that extended side and the adjacent side of the triangle.

The measure of an exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it.

Now, consider a triangle with interior angles of 70, 60, and 50 degrees. If we extend the side opposite the 70-degree angle, we get an exterior angle of 110 degrees. However, 110 degrees is not obtuse, since an angle is obtuse if and only if it is greater than 90 degrees. Therefore, we have shown that an exterior angle of a triangle does not always have to be obtuse.

In summary, the statement "an exterior angle of a triangle will always be obtuse" is false, and we have provided a counterexample to show why this is the case.

Answer: the positive value of tan(1/2x) in simplest radical form with a rational denominator is √(2/3).

Step-by-step explanation:

Using the half-angle formula for tangent, we have:

tan(1/2x) = ±√((1-cos(x))/(1+cos(x)))

Substituting cos(x) = 1/5, we get:

tan(1/2x) = ±√((1-1/5)/(1+1/5))

= ±√(4/6)

= ±√(2/3)

Since we are looking for the positive value, we have:

tan(1/2x) = √(2/3)

Therefore, the positive value of tan(1/2x) in simplest radical form with a rational denominator is √(2/3).

Answer:

Step-by-step explanation:

sin(x)=sqrt(24)/5=2*sqrt(6)/5

tan(x/2)=sin(x)/(1+cos(x))

Thus, tan(x/2)=sqrt(6)/3

The number of cartons of face masks and hand - sanitizers that Mod World bought were 19 cartons of cloth face masks and 5 cartons of hand sanitizer from Maleri Designs.

Let's assume that Mod World purchased x cartons of cloth face masks and y cartons of hand sanitizer.

The simultaneous equations would be :

x + y = 24

10x + 4y = 210

Using substitution we get the value of x to be:

x = 24 - y

When put in the second equation this is:

10x + 4y = 210

10(24 - y) + 4y = 210

240 - 10y + 4y = 210

-6 y = -30

y = 5

x would then be:

x + y = 24

x + 5 = 24

x = 19

The value of z is 27 when the value of w is 5, when w varies inversely with z.

The ratio of two proportional values at a constant value is the proportionality constant. When either the ratio or the product of two variables results in a constant, the connection between the two is proportional. The ratio between the two stated quantities affects the proportionality constant's value. Direct variation and inverse variation are two different sorts of this relationship.

Given that, w is 15 when z is 9, and w varies inversely with z.

This can be represented as:

w = k (1 /z)

where, k is the proportionality constant.

Substituting the value of w = 15 and z = 9 we have:

15 = k(1/9)

k = 15(9)

k = 135

Substituting the value of k and w = 5:

5 = 135(1/z)

z = 135/5

z = 27

Hence, the value of z is 27 when the value of w is 5.

The length of the base of the given isosceles triangle is 18.

What is an isosceles triangle?

A triangle with two equal sides is known as an isosceles triangle in geometry. Both having exactly two sides of equal length and having at least two sides of equal length are acceptable specifications, with the latter version containing the equilateral triangle as an exception. The theorem that describes the isosceles triangle is, "if the two sides of a triangle are congruent, then the angle opposite to them is likewise congruent."

Given the sides of the triangle as 2x+4, x+8 and 5x-2

∠A and ∠B are given as same.

So this is an isosceles triangle.

One of the properties of an isosceles triangle is that the opposite angle of an isosceles triangle will also be equal if the sides are equal. As a result, if two sides are equal, so will the two angles that are across from them.

So 2x + 4 = x + 8

Solving, we get x as

x = 4

So now substituting this value in 5x -2, which is the base of the triangle.

5 * 4 -2 = 20 - 2 = 18

Therefore the length of the base of the given isosceles triangle is 18.

Answer:

Fruit mass = 63.2 g

Biscuit mass = 94.8 g

Step-by-step explanation:

Since the ratio of fruit mass to biscuit mass is 2:3, the fraction of fruit mass to the total of fruit and biscuit mass is 2/5 and the fraction of biscuit mass to the total of fruit and biscuit mass is 3/5.

For Monkey A, the total of fruit and biscuit mass is 73 g, which means that the fraction of fruit mass is 2/5 × 73 g = 29.2 g and the fraction of biscuit mass is 3/5 × 73 g = 43.8 g. Therefore, the values for fruit mass and biscuit mass are:

Fruit mass = 29.2 g

Biscuit mass = 43.8 g

For Monkey B, the total of fruit and biscuit mass is 73 + 85 = 158 g, which means that the fraction of fruit mass is 2/5 × 158 g = 63.2 g and the fraction of biscuit mass is 3/5 × 158 g = 94.8 g. Therefore, the values for fruit mass and biscuit mass are:

Fruit mass = 63.2 g

Biscuit mass = 94.8 g

The equation of the lines with the points (-8, 3) and (-6, 0) is y = -3x/2 + 9.

The equation of the lines with the points (5, 4.5) and (5, -1) is y = 4.5.

In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

At data point (-8, 3), a linear equation in standard form for this line can be calculated by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 3 = (0 - 3)/(-6 + 8)(x + 8)

y - 3 = -3x/2 - 12

y = -3x/2 + 9

For points (5, 4.5) and (5, -1), we have:

At data point (5, 4.5), a linear equation in standard form for this line can be calculated by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 4.5 = (-1 - 4.5)/(-5 - 5)(x - 5)

The total annual income from both investment is

(14x -65000)/100

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

I = x× 9/100

I = 9x/100

(13000 - x) × 5/100

= (65000-5x)/100

therefore the total amount annual income

= 9x /100 - (65000-5x)/100

= (9x+5x-65000)/100

The probability that the random sample of 100 male students has a mean gpa greater than 3. 42 is 0.9452.

A statistic known as the standard deviation is used to describe how volatile or dispersed a group of numerical values is. While a big standard deviation denotes that the values are scattered across a wider range, a low standard deviation indicates that the values tend to be close to the set mean.

From the given information, a scores random sample of 100 male students is selected and the GPA for each student is calculated which follows approximately normal with a mean of 3.5 and standard deviation of 0.5. That is,

µ = 3. 5 and σ = 0. 5

and the random sample of 100 male students has a mean GPA 3.42 is considered.

The z-score value is,

Z=( 3.42-3.5)/ (0.5/√100)

Z= -0.08/0.05

Z=-1.6

The value of z-score is obtained by taking the difference of x and µ. Then the resulting value is divided with the standard deviation by sample size.

The probability that the random sample of 100 male students has a mean GPA greater than 3.42 is obtained below:

The required probability is,

P(X>3.42)=P(z>-1.6)

= 1- P(Z≤-1.6)

From the “standard normal table”, the area to the left of Z=-1.6 is 0.0548.

P(X>3.42)= 1- P(Z≤-1.6)

The first three terms of the AP are -4.28, -7.28, -10.28

An arithmetic sequence in algebra is a sequence of numbers where the difference between every two consecutive terms is the same.

Given that, the sum of the first 9 terms of an AP is 56 and the sum of the next 10 terms is 430. we need to find the first three terms of the AP.​

The sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ). It is called the arithmetic series formula.

Therefore,

56 = 9/2(2a₁+(9-1)d)

12.44 = 2a₁+7d

2a₁ = 12.44-7d....(i)

430 = 19/2(2a₁+18d)

45.26 = 2a₁+18d

2a₁ = 45.26-18d....(ii)

Equating the RHS of the equations,

12.44-7d = 45.26-18d

11d = 32.82

d = 3

Put d = 3, in equation (i)

2a₁ = 12.44-7(3)

2a₁ = -8.56

a₁ = -4.28
