The area of irregular shapes can be determined by dividing the given shape into smaller regular shapes. The area of irregular shapes can be determined by dividing the given shape into smaller regular shapes.

In real life figures are often irregular shapes - a little bit messy. Think of your messy bedroom once more ‐ is it a perfect rectangle?

The trick is to break these figures into shapes that you know well and whose area you know how to find.

1. Find the area of this room:

3- 2 -4 -6 irregular shape

This can be done in two different ways but ill only give one example on how to find an area.

Method #1

Divide the figure into two rectangles and find all missing lengths.

The larger rectangle has an area of

4cm x 7cm = 28cm2

The smaller rectangle has an area of

4cm x 2cm = 8cm2

If we combine these we will find the total area:

28cm2 x 8cm2 = 36cm2

Two spheres have volumes of 8π cm3 and 64π cm3. if the surface area of the smaller sphere is 16π cm2, what is the surface area of the larger sphere? 64π cm2 96π cm2 128π cm2 256π cm2

Answers

The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.

The volume of the larger sphere = 64π cm³

let us take the radius of the larger sphere r

So, 4/3*π*r³ =64π

r³=48

r=2∛6

What is the surface area of a sphere?

The surface area of a sphere with radius r is 4πr².

So, the surface area of the larger sphere = 4π(2∛6)²

The surface area of the larger sphere = 16π∛36

Hence, The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.

What is linear regression?

Linear regression is a type of regression which is used to model the statement in which the growth or decay initially with constant rate, and then slow down with respect to time.

The table shows the temperature of an amount of water set on a stove to boil, recorded every half minute. a 2-row table with 10 columns.

Time (minutes X) 0, 0.5,1.0, 1.5, 2.0,2.5,3.0, 3.5, 4, 4.5. Temperature (° Celsius Y) 75, 79, 83, 86, 89, 91, 93, 94, 95, 95.5.

The sum of time is 22.5 and the sum of temperature value is 880.5. In this table,

The mean of time value, 2.25.The mean of temperature value 88.05Sum of squares 20.625Sum of products 93.625

The regression equation for this data can be given as,

[tex]\hat y=4.53939 X+77.83636[/tex]

Put the value of temperature (y) 100 in this equation.

[tex]100=4.53939 X+77.83636\\X=\dfrac{100-77.83636}{4.53939}\\X\approx 5[/tex]

Hence, according to the line of best fit, the value of time when the temperature reach 100°c, the boiling point of water is 5.

In some countries, people believe that blood type has a strong impact on personality. For example, Type B blood is thought to be associated with passion and creativity. A statistics student at a large U. S. University decides to test this theory. Reasoning that people involved in the arts should be passionate and creative, she takes a simple random sample of students majoring or minoring in arts at her university and asks them for their blood type. Here are her results:

Observed number of performing arts majors with each blood type

Type A Type B Type AB Type 0 Total

50 23 10 67 150

Assume the distribution of blood type among all U. S. Residents is as follows:

Type A: 42%; Type B: 10%; Type AB: 4%; Type O: 44%.

(a) The student wants to carry out a test of significance to see if the distribution of blood types among arts majors or minors is different from the U. S. Distribution. State the null and alternative hypotheses for this test.

(b) Find the expected counts for each blood type under the assumption that the null hypothesis is true.

(c) Discuss whether the conditions for this test have been met.

(d) Find the value of the test statistic and the P-value of the test, and make the appropriate conclusion. Use α = 0. 5.

(e) Based on your answer to (d), which error is it possible that you have made, Type I or Type II? Describe that error in the context of the problem

Answers

The null hypothesis for the test regarding the blood type is that they distribution of blood types among art major is the same as the US distribution.

What is a null hypothesis?

It should be noted that null hypothesis simply suggests that there is no statistical relationship.

Here, the null hypothesis for the test regarding the blood type is that the distribution of blood types among art major is the same as the US distribution and the alternative hypothesis is that the distribution of blood types among art major is different from the US distribution.

The conditions for this test have been met as all expected frequencies are greater than 5.

Since the test statistic is 9.63 and the p-value is 0.022, one can reject the null hypothesis. Therefore, it'll be concluded that the distribution of blood types among arts majors and minors is different from the U.S distribution.

What is a Complex number?

The numbers which can be expressed in the form of a + ib, where both 'a' and 'b' are real numbers and 'i' an imaginary number is called complex numbers.

So a complex number has a real part and an imaginary part.

The imaginary number 'i' is called iota and value of i is √-1.

We know the value of i.

i = √-1

i² = -1

(5i)² only has an imaginary part.

∴ (5i)² = 5² i²

= 25 × -1

= -25

Find the nature of the roots of 4x ^ 2 + 6x - 7 = 0

a. complex
b. irrational
c. rational
d. real and equal

Answers

Answer:

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 (a ≠ 0 )

the discriminant b² - 4ac informs us about the nature of the roots

• If b² - 4ac > 0 then roots are real and irrational

• If b² - 4ac > 0 abd a perfect square then roots are real and rational

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 the roots are complex

4x² + 6x - 7 = 0 ← is in standard form

with a = 4, b = 6, c = - 7 , then

b² - 4ac = 6² - (4 × 4 × - 7) = 36 - (- 112) = 36 + 112 = 148

since b² - 4ac > 0 then roots are real and irrational

100 POINTS solve the system using linear combination. show all work.{ 5x + 3y = 41 {3x - 6y = 9

Answers

Answer:

y = 2

x = 7

Explanation:

5x + 3y = 413x - 6y = 9

Make the coefficient of "y" in equation 1 same

{ 5x + 3y = 41 } * 2 → 10x + 6y = 82 ........equation 1

→ 3x - 6y = 9 ........equation 2

solving them using linear combination

10x + 6y = 823x - 6y = 9

============

13x = 91x = 7

Find y:

5x + 3y = 415(7) + 3y = 413y = 41 - 353y = 6y = 2

5x+3y = 41 multiply whole thing by -2 so the y’s cancel out
3x-6y = 9

Becomes
-10-6y=-82
- subtract
3x-6y = 9

=
-13x+0y=-91

What is the total length of the tadpoles that are 1/8-inch and 1/4-inch long?

7/8 inches
1 1/8 inches
5/8 inches
3/8 inches

Answers

The dot plot shows the frequency or length of the tadpoles

The total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

How to determine the total length?

From the dot plot, we have the following parameters:

3 tadpoles have a length of 1/82 tadpoles have a length of 1/4

So, the total length is:

Total = 3 * 1/8 + 2 * 1/4

Evaluate the product

Total = 3/8 + 1/2

Rewrite as;

Total = 3/8 + 4/8

Evaluate the sum

Total = 7/8

Hence, the total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches
