The number of people corresponds to are (a) 26, (b) 38, (c) 3, (d) 20, (e) 34, (f) 61 and (g) people who are correct but don't exercise regularly.

Venn diagram is a diagram of circles used to show the relationships of finite groups of things.

Here a Venn diagram relating the number of people who are correct and who exercise regularly are given.

Given,

Total number of people (Universal set), U = 49

Number of people who are correct = 18 + 20 = 38

Number of people who exercise regularly = 3 + 20 = 23

(a) Number of people who don't exercise regularly = 49 - 23 = 26

(b) Number of people who were correct = 38

(c) Number of people who were incorrect and exercise regularly = 3

(d) Number of people  who exercise regularly were correct = 20

(e) Number of people who were incorrect or exercise regularly = people who were incorrect + people who exercise regularly

= (49 - 38) + 23 = 11 + 23 = 34

(f) Number of people who were either correct or exercise regularly = people who were correct + people exercise regularly

= 38 + 23 = 61

(g) The 18 people in the left circle of diagram are people who are correct but don't exercise regularly.

Hence the number of people in all aspects are found.

Finding the rate of the weight gain, we divide the total weight gained with the total number of months that took to gain that weight.

Total time (months) = 0.5 + 2 + 3.5 = 6 months

Total weight (kg) = 80.6 + 88.4 + 96.2 = 265.2 kilograms

Rate = Kg ÷ Months

Rate = 265.2 ÷ 6 = 44.2

When testing differences between the mean scores of more than two unconnected groups, the appropriate statistical technique to select is analysis of variance ANOVA.

When comparing the means of more than two unconnected groups, ANOVA is the appropriate statistical technique to use. ANOVA allows for the analysis of variance between multiple groups simultaneously. It tests whether there are significant differences in means among the groups based on the variability within and between the groups. ANOVA provides an F-statistic and associated p-value to determine if there are significant differences in means.

The dependent samples t-test (option b) is used when comparing the means of two related groups, where the same subjects are measured under different conditions or at different times. Regression (option c) is a statistical technique used to model the relationship between a dependent variable and one or more independent variables. The independent samples t-test (option d) is appropriate when comparing the means of two independent groups. However, when dealing with more than two groups, ANOVA is the preferred method as it allows for a comprehensive analysis of variance across all groups simultaneously.

DM is congruent to line CM because CDM is congruent to triangle CBM using the SAS congruence criteria for triangles.

Draw a diagram of the rectangle ABCD with M as the midpoint of AB. Draw lines CM and DM ( refer to the attached image). Since AB is a line segment, we know that AM is congruent to MB (because M is the midpoint of AB). Since ABCD is a rectangle, we know that AB is parallel to CD, and AD is parallel to BC. Thus, we have two pairs of parallel lines: AB and CD, and AD and BC.

Using the fact that opposite sides of a rectangle are congruent, we have CD = AB. Now, we have a pair of congruent sides (DM and CM) that are opposite each other in triangle CDM and CBM respectively. We also have another pair of congruent sides (CD and AB) that are opposite each other in both triangles. Finally, we know that the angle CMD is congruent to the angle CMB because they are vertical angles. By the Side-Angle-Side (SAS) congruence criterion, we can conclude that triangle CDM is congruent to triangle CBM.

Therefore, line DM is congruent to line CM by SAS congruence criteria.

The value of missing number in given linear equation to have no solution should be greater than 4.

What is a linear equation ?

A linear equation is an equation that, when graphed on a coordinate plane, shows a straight line. It's an algebraic equation constant terms or the product of a constant and variable. A linear equation has the basic form y = mx + b, where y and x are variables, m is the slope, and b is the y-intercept.

Now,

Expanding the equation

-4x + 20 = ?x + 9

Subtracting ?x from both sides gives:

-4x + ?x + 20 = 9

Simplifying gives:

(4 - ?)x + 20 = 9

Subtracting 20 from both sides gives:

(4 - ?)x = -11

Since x cannot be negative and 4 - ? is positive, for this equation to have no solution, we need (4 - ?)x to be negative for all x. Therefore, we need 4 - ? to be negative, which gives:

4 - ? < 0

? > 4

So, if we choose any number greater than 4 for ?, the equation will have no solution. For example, if we let ? = 5, then the equation becomes:

4(-x+5) = 5x+9

Simplifying this equation gives:

-4x + 20 = 5x + 9

-9x = -11

x = 11/9

Therefore, the missing number ? must be greater than 4 to ensure that the equation has no solution.

After 4 hours of discharging, the volume left in the tank would be 500 liters. The correct option is C.

Initially, the tank has a water capacity of 1500 liters.

After three hours of discharging, half of the water is discharged, which means 1500/2 = 750 liters have been removed from the tank.

To find the volume left after 4 hours of discharging, we need to subtract the additional amount discharged in the fourth hour.

Since the discharge rate remains the same, we can calculate the amount discharged in one hour as 750/3 = 250 liters.

Therefore, in the fourth hour, 250 liters would be discharged. Subtracting this from the remaining water after three hours (750 liters), we get 750 - 250 = 500 liters.

Therefore, the correct answer is c. 500 liters.

Whenever you have two groups like this, one labeled the treatment group and the other the control group, we have an experiment gong on.

The treatment group gets the actual medication that is being tested. The control group gets a fake medication, aka placebo. Usually a placebo is meant for humans because it's more of a psychological factor. With cats, it likely won't affect them. However, such practices of having two groups like this is standard no matter what group of subjects you're testing.

The idea is that if the treatment group has better results compared to the placebo group, then it's likely the medication works.

The line integral ∫[C] (Pdx + Qdy) over the given curve C consisting of the arc of the parabola y = x² from (0,0) to (1, 1), and the line segment from (1,1) to (0,1) is equal to 2/5.

What is integral?

The value obtained after integrating or adding the terms of a function that is divided into an infinite number of terms is generally referred to as an integral value.

To evaluate the line integral using Green's theorem, we need to find a vector field F = (P, Q) such that ∇ × F = Qₓ - Pᵧ, where Qₓ represents the partial derivative of Q with respect to x, and Pᵧ represents the partial derivative of P with respect to y.

Let's consider F = (P, Q) = (x²y², xy).

Now, let's calculate the partial derivatives:

Qₓ = ∂Q/∂x = ∂(xy)/∂x = y

Pᵧ = ∂P/∂y = ∂(x²y²)/∂y = 2x²y

The curl of F is given by ∇ × F = Qₓ - Pᵧ = y - 2x²y = (1 - 2x²)y.

Now, let's find the line integral using Green's theorem:

∫[C] (Pdx + Qdy) = ∫∫[R] (1 - 2x²)y dA,

where [R] represents the region enclosed by the curve C.

To evaluate the line integral, we need to parameterize the curve C.

The arc of the parabola y = x² from (0, 0) to (1, 1) can be parameterized as r(t) = (t, t²) for t ∈ [0, 1].

The line segment from (1, 1) to (0, 1) can be parameterized as r(t) = (1 - t, 1) for t ∈ [0, 1].

Using these parameterizations, the region R is bounded by the curves r(t) = (t, t²) and r(t) = (1 - t, 1).

Now, let's calculate the line integral:

∫∫[R] (1 - 2x²)y dA = ∫[0,1] ∫[t²,1] (1 - 2t²)y dy dx + ∫[0,1] ∫[0,t²] (1 - 2t²)y dy dx.

Integrating with respect to y first:

∫[0,1] [(1 - 2t²)(1 - t²) - (1 - 2t²)t²] dt.

Simplifying:

∫[0,1] [1 - 3t² + 2t⁴] dt.

Integrating with respect to t:

[t - t³ + (2/5)t⁵]_[0,1] = 1 - 1 + (2/5) = 2/5.

Therefore, the line integral ∫[C] (Pdx + Qdy) over the given curve C consisting of the arc of the parabola y = x² from (0,0) to (1,1), and the line segment from (1,1) to (0,1) is equal to 2/5.
