the y intercept is 2 in both cases

Step-by-step explanation:

the y intercept is where it crosses the y axis

y intercept =2

the function y = 3x+2 is in the form y= mx+b

where b is the y intercept

b=2  so the y intercept is 2

2=2 so the y intercepts are equal

Answer:

$1431

Step-by-step explanation:

If Stan pays a 10% deposit, he pays $159. 10% of $1590 is simply 0.1 * 1590 = 159. Assuming this is the only amount he pays, he then simply needs to pay the full price minus $159. We can find this by simply subtracting 159 from 1590 to get 1431. Stan still needs to pay $1431.

Answer: C. At the α=0.05 significance level, they should conclude that more than 50% of adults support the tax increase.

Step-by-step explanation:

Given: Null hypothesis: \(H_0:p=0.5\)

Alternative hypothesis: \(H_a: p>0.5\)

p-value = 0.033

If the p-value is greater than alpha (p > . 05), then we fail to reject the null hypothesis.

If α=0.01 , then p-value > α i.e. we fail to reject the null hypothesis.

Conclusion: Exactly 50% of adults support the tax increase.

If α=0.05 then p-value < α i.e. we reject the null hypothesis.

Conclusion: more than 50% of adults support the tax increase.

Thus, Correct option: C .

Answer:

The z-statistic for a 99% confidence interval for the population mean is 2.575.

Step-by-step explanation:

We have that to find our \(\alpha\) level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\(\alpha = \frac{1 - 0.99}{2} = 0.005\)

Now, we have to find z in the Ztable as such z has a pvalue of \(1 - \alpha\).

That is z with a pvalue of \(1 - 0.005 = 0.995\), so Z = 2.575.

The z-statistic for a 99% confidence interval for the population mean is 2.575.

Based on the given information, one of the acute angles in the triangle is 22 degrees, and another measures 68 degrees.

In any triangle, the sum of the three interior angles is 180 degrees. Therefore, in this right-angle triangle,

90 + X + 3X + 2 = 180

4X + 92 = 180

4X = 180 - 92

4X = 88

X = 22

So, one of the acute angles in the triangle is 22 degrees.

Now, we can find the third angle using the fact that the sum of the three angles in a triangle is 180 degrees:

90 + X + 3X + 2 = 180

4X + 92 = 180

4X = 88

3X + 2 = 68

Therefore, the third angle in the triangle measures 68 degrees.

Answer:

If its radius is 9 cm, it’s circumference would be two times radius times pi equal to 18 pi. Also its area is pi R squared which is equal to 81 pi.  Circumference = 18 pi  Area = 81 pi  Area is 4.5 times greater than the circumference. The answer is C.

Answer:

Those two quantities are incommensurate, you can't compare them. The circumference is a length and the area is an area. There is no way to compare the two.

Now if you're talking about the formula Area = circumference squared over 4 times Pi, and if you're just going to go with the numerical values of Area and circumference, then there is an answer.

The teacher can thus use social sciences as a vehicle to develop mathematical skills by facilitating the development of skills such as data interpretation and analysis.

As an instructor, I would use social sciences to develop mathematical skills in the following manner:Consider a social science topic like demography. In this case, a teacher could use mathematics to assist students in interpreting population statistics.

Teachers might guide students to gather information about population size, growth rate, and geographical distribution from various countries and then use statistics to analyze the data.

For example, a teacher could give students graphs or charts to help them understand population growth rates. They can be asked to make comparisons and identify trends.

In this way, students' understanding of the population is improved, as is their mathematical reasoning.Aside from using mathematics to interpret population statistics,

the teacher can also incorporate mathematical skills development in social sciences by using methods that involve understanding and analysis of data. In other words, students learn how to use data to reach conclusions and make decisions.

They learn how to interpret data and how to extract information from it.This method of teaching creates opportunities for the use of the same skills in different contexts and areas of learning.

A possible length, width, and height of the box with the desired diagonal of at least 41.5 inches, obtained using Pythagorean Theorem is specified by option a.

a. 23 inches, 24 inches, 25 inches

Pythagorean Theorem states that the square of the hypotenuse side of a right triangle is the sum of the square of the lengths of the legs of the right triangle.

The desired length of the diagonal of the box d ≥ 41.5 inches

The length of the box = l

The width of the box = w

The height of the box = h

The formula for the diagonal of the box, obtained using Pythagorean Theorem is d = √(l² + w² + h²)

Therefore, the square of the diagonal of the box, d²  ≥ 41.5² = 1722.25

d² = l² + w² + h²

l² + w² + h² ≥ 1722.25

20² = 400

21² = 441

22² = 484

23² = 529

24² = 576

25² = 625

26² = 676

27² = 729

Therefore; 23² + 24² + 25² = 1730 > 1722.25

20² + 20² + 27² = 1529 < 1722.25

21² + 24² + 26² = 1693 < 1722.25

20² + 21² + 26² = 1517 < 1722,25

The areas of the composite figures are 36 square units, 27 square units, 66 square units, 32+2π square units and 68 square units  respectively.

What are composite figures?

A composite figure is a shape that is produced from two or more fundamental shapes. Composite figures are also referred to as compound and complex shapes frequently.

Figure 1

This figure can be broken into two rectangles.

First rectangle with length 5 and width 4.

Second rectangle with length 8 and width 2 (as 6-4 is 2).

Area of rectangle= length*width

So, area of first rectangle= 5*4= 20 square units

Area of second rectangle= 8*2= 16 square units

Thus,

Area of figure= 20+16= 36 square units

Figure 2

This figure can be broken into two rectangles.

First rectangle with length 7 and width 3(as 6-3 is 3).

Second rectangle with length 2 and width 3.

Area of rectangle= length*width

So, area of first rectangle= 7*3= 21 square units

Area of second rectangle= 2*3= 6 square units

Thus,

Area of figure= 21+6= 27 square units

Figure 3

This figure can be broken into two rectangles.

First rectangle with length 12 and width 5.

Second rectangle with length 3 and width 2(as 12-(6+4) is 2).

Area of rectangle= length*width

So, area of first rectangle= 12*5= 60 square units

Area of second rectangle= 3*2= 6 square units

Thus,

Area of figure= 60+6= 66 square units

Figure 4

This figure can be broken into a rectangle and a semicircle.

Rectangle with length 8 and width 4.

Semi-circle with radius 2 ( as diameter is 4).

Area of rectangle= length*width

So, area of rectangle= 8*4= 32 square units

Area of semi-circle= 1/2πr^2

So, area of semi-circle= 1/2π(2)^2= 2π square units

Thus,

Area of figure= 32+2π square units

Figure 5

This figure can be broken into a rectangle and two squares.

Rectangle with length 10 and width 6(as 8-2 is 6).

Both squares with side 2.

Area of rectangle= length*width

So, area of rectangle= 10*6= 60 square units

Area of square= side^2

So, area of first square= 2^2= 4 square units

area of second square= 2^2= 4 square units

Thus,

Area of figure= 60+4+4= 68 square units

Hence, the areas of the composite figures are 36 square units, 27 square units, 66 square units, 32+2π square units and 68 square units  respectively.

The measure of angle DCE in this problem is given as follows:

m < DCE = 22.5º.

The triangles in this problem are right triangles, meaning that the trigonometric ratios are used to find the measures.

The three trigonometric ratios are given as follows:

The segment DB is adjacent to angle of 38º, while the hypotenuse is of 12.2 cm, hence the length of segment DB is calculated as follows:

cos(38º) = DB/12.2

DB = 12.2 x cosine of 38 degrees

DB = 9.6 cm.

BE:ED = 3:1, means that segment DE is one-fourth of segment DB, and thus it's length is given as follows:

DE = 1/4 x 9.6

DE = 2.4 cm.

Then for the angle DCE, we have that the opposite side is of 2.4 cm while the adjacent side is of 5.8 cm, hence the tangent is used to find it's measure, as follows:

tan(x) = 2.4/5.8

x = arctan(2.4/5.8)

x = 22.5º

m < DCE = 22.5º.

Answer:

x = 22.5°

Step-by-step explanation:

The central angle is approximately 2.357 radians.

To find the central angle, we can use the formula:

Central angle (θ) = arc length ÷ radius

Given:

Arc length (mXY) = 18 in

Radius (ZY) = 7.64 in

Plugging in the values:

Central angle (θ) = 18 in ÷ 7.64 in

Calculating the division:

θ ≈ 2.357 radians

Therefore, the central angle is approximately 2.357 radians.

Answer:

Last option, $58.50

Step-by-step explanation:

Let's look at the graph, and let's do a simple analysis of the information that it shows.

We can see that in 2009, the price was between $30 and $40.

We can see that as the years pass by, the price increases, such that in the year 2013 the selling price spikes and ranges between a bit less than $50 to a little more than $50.

Then we can only expect that a few years later (in 2016) the price to be larger than $50.

The only option that has a price larger than $50 is the last one, $58.50, then that one is the only option that can be the correct one.

We also could do an exact calculation of this if we had the raw data, but as you can see in the graph, we can not know the exact price of each graphed point (we can only estimate it) so we will not get a nice interpolation by only using the given graph.
