A type of green paint us made by mixing 2 cups of yellow with 3.5 cups of blue. a. Find a mixture that will make the same shade of green but larger amount.

Answers

Answer 1

Step-by-step explanation:

easiest example : multiply both (it is important to do it to both) by 2 :

2×2 = 4 cups of yellow

3.5×2 = 7 cups of blue

will make the same shade of green, as the mixing ratio is the same.

just, instead of 5.5 cups, it gives us 11 cups of green paint (surprise, surprise, this is also twice as much) .

a right triangle has a hypotenuse of length 3 units and one side of length 2 units. what is the area of the triangle?

Answers

The area of the triangle is 3 units² which has a hypotenuse of 3 units and a side of 2 units.

What is a triangle?

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon.

There are three sides and three angles in every triangle, some of which may be the same.

In the case of a right triangle, the three sides are given unique names: the hypotenuse, which is the side that faces the right angle, and the legs, which are the other two sides.

Every triangle is bicentric and convex.

The triangle's interior is the area of the plane it encloses; the outside is the rest of the plane.

So, the area of the triangle will be:

We know that the hypotenuse is 3 units.

The length of the other side is 2 units.

Area of triangle formula: 1/2 * base * height

Now, insert values in the formula and calculate:

1/2 * base * height

1/2 * 2 * 3

3 units²

Therefore, the area of the triangle is 3units² which has a hypotenuse of 3 units and a side of 2 units.

Answers

The evidence is not sufficient to support the claim since the p-value is 0.1833 higher than 0.05, so e) none of the preceding.

How to find p-value?

α = significance level = 0.05

n = sample size

df = degree of freedom = n - 1 = 10 - 1 = 9

Before we find the p-value, we use t test formula. But, before that we calculate mean and standard deviation for two population with excel.

In excel we get,

[tex]\bar x_1[/tex] = 231.8

[tex]\bar x_2[/tex] = 214.8

[tex]\sigma_1[/tex] = 41.95

[tex]\sigma_2[/tex] = 37.90

Next, we can calculate t test. So,

t = [tex]\frac{\bar x_1 -\bar x_2}{\sqrt{\frac{\sigma^2_1+\sigma^2_2}{n}}}[/tex]

= [tex]\frac{231.8-214.8}{\sqrt{\frac{41.95^2+37.9^2}{10}}}[/tex]

= [tex]\frac{17}{\sqrt\frac{3,196.2125}{10}}[/tex]

= 0.9509

Using t score to p-value calculator for 0.9509, we get p-value = 0.1833.

Thus, the p-value is 0.1833 is higher than significance level 0.05 so there is no sufficient evidence to support the claim.

Answers

Answer:

Step-by-step explanation:

1.Φ(u,v) gives the parametrization with its x, y, and z components. So, x=7u+4, y=u-v, and z=13u+v. We can use this to get the tangent vectors by taking the respective partial derivatives. Tu=<7, 1, 13> by taking the u derivatives of the components and Tv=<0, -1, 1> by taking the v derivatives of the components.

2. Taking the cross product of Tu and Tv will give the normal vector n(u,v), which is <14, -7, -7>

3. To find Area(S), you have to multiply the area of D by the magnitude of the normal vector from the previous step. D is the region defined by 0<=u<=5 and 0<=v<=6, so the area of D is 5*6=30. Multiply this by the magnitude of the normal vector to find that Area(S)=30sqrt(294)

4. To integrate, we first must put the initial function in terms of the parameters we found in the first step. Replace y with u-v and z with 13u+v. Next, multiply this integrand by the magnitude of the normal vector (sqrt294) and apply the given bounds for u (0<=u<=5) and v (0<=v<=6). From here the problem can be integrated like any other double integral, the final answer being 190sqrt(294)

Answers

The percent of the wall does she paint will be;

⇒ 79%

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The length of room wall = 8 feet

The width of room wall = 12 feet

The length of windows = 5 feet

The width of windows = 2 feet

Now,

The area of wall = 12 x 8 feet²

                         = 96 feet²

And, The area of windows = 5 x 2 feet²

                                         = 10 feet²

Hence, The area of paints a wall in her bedroom = 96 - 2 (10)

                                                                            = 96 - 20

                                                                            = 76 feet²

So, She paint the wall of area 76 feet².

Since, The area of whole wall = 96 feet²

But, There are two window.

So, The percent of only wall paint of are 76 feet² = 100 x 76 / 96

                                                                            = 79.16%

Thus, The percent of the wall does she paint to the nearest whole percent will be;

                        170g = 1.70 x 10⁻¹ kg.

Since there are a thousand milliliters in a liter and a thousand liters in a cubic meter

               100ml = 1.00 x 10⁸ cubic meters

Therefore, Density= mass/volume

Density = 1.7 x 10⁻¹/ 1.00 x 10⁸ kg/m³

             = 0.17 x 10⁸ kg/m³.

geometry classifying triangles

Answers

The classification of the following triangles are below:

Diagram 1: Scalene triangle. option BDiagram 2: Equilateral triangle. option ADiagram 3: Isosceles triangle. option BDiagram 4: Acute triangle. option ADiagram 5: The value of a in the convex polygon is 40°Diagram 6: The value of s from the measure is 27Diagram 7: The value of m < 1 is 56°Diagram 8: The value of m < 1 is 120°

The types of triangle

The types of triangle includes:

Scalene: A triangle having each of its three sides of different lengths.

Equilateral triangle: A triangle having all three sides equal.

Isosceles triangle: A triangle having two sides equal.

Obtuse triangle: A triangle in which one of whose angles is obtuse, that is, an angle greater than 90° but less than 180°

Acute triangle: A triangle which all of the angles are acute, that is, all interior angles are less than 90°

Right angle triangle: A triangle all of the angles of which are acute.

5. a = 180° - (56° + 84°)

= 180° - 140°

= 40°

6.

5s + (3s - 9) + 45 = 180

5s + 3s - 9 + 45 = 180

8s - 36 = 180

8s = 180 + 36

8s = 216

s = 216/8

s = 27

7. 180° - 139° = 41°

m < 1 = 180° - (41° + 83°)

= 180 - 124

m < 1 = 56°

180° - (68° + 52°)

= 180 - 120

= 60°

m < 1 = 180° - 60°

= 120°

Therefore, a triangle is a three sides polygon which also have three angles.

geoff is about to open a restaurant. he has found two possible locations for the restaurant; one closer to the central business district (cbd) and one in the suburbs. geoff is concerned that if he chooses the cbd location, he will have to charge higher prices for his food to cover the higher rent. geoff is uncertain of the affect that this will have on his annual revenue. to help with his decision, geoff will carry out a multiple regression analysis to predict the annual revenue earned by restaurants based on their distance from the cbd in miles and the average price in dollars charged for a dish. geoff has collected a sample of 50 restaurants that are randomly spread around the city. the proximity to the cbd (x1i), average price of a dish (x2i) and annual revenues (yi) were recorded for each of these restaurants (i = 1, 2, ..., 50). Geoff believes that a multiple linear regression is appropriate for this data. After carrying out some analysis, geoff has noticed that moving one mile away from the CBD (assuming that the average price of a dish is held constant) will result in a decrease of $60,000 in annual revenues. Geoff has also noticed that increasing the average price of a dish by $1 (assuming that the distance from the CBD is held constant) will result in an increase of $40,000 in annual revenues. The data shows that a restaurant at the center of the CBD that gave away its food for free would have an annual loss of $20,000. Select the multiple linear regression equation that corresponds to Geoff's analysis: o ĝi = -20,000 - 60,000x11 + 40,000x2i o ĝi = 20,000 + 60,000x11 - 40,000x2i O Vi = -20,000 + 40,000x11 - 60,000x2i © y = 20,000 - 40,000x13 + 60,000x2i

Answers

The multiple regression linear regression equation is:

i = -20000 + -60000*x1i + 40000*x2i

The multiple regression equation here will be of the form

i = a*x1i + b*x2i + c

Where i is the annual revenue

a is the coefficient of x1i which is distance from CBD

where b is the coefficient of x2i average price of a dish

C is the constant term.

Given that moving one mile away from the CBD x1i , the annual revenues will i will decrease by $60000. So, the coefficient of x1i, a is -60000

Given that increasing the average price of dish x2i by $1 , the annula revenue will i will increase by $40000. So the coefficient of x2i, b is 40000

The data shows  that the restaurant at the center of the CBD which means, x1i = 0 and giving away its food for free which means x2i = 0 is resulting in a loss of $20000. so the value of the constant term is c=20000.

so the multiple regression linear regression equation is:

i = -20000 + -60000*x1i + 40000*x2i

hence option A is correct
