How do you find the surface area of "most" 3D solids?

Answers

Answer:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:

 3y-2=10

Step-by-step explanation:

Given;

Which of the following does Not belong to the group?

2x > 5 - x

3(x-4) [tex]\leq[/tex] -23

3y - 2 = 10

a < 13a + 1

Solve;

Base on the given data, we can infer that "3y-2=10" does Not belong to the group. You can see that other have Python. Python has six comparison operators: less than ( < ), less than or equal to ( <= ), greater than ( > ), greater than or equal to ( >= ), equal to ( == ), and not equal to ( != ). While, "3y-2=10" doesn't have one.

As well as if you simplify/solve these other will be given as a fraction while "3y-2=10" answer is a whole number.

Solution of each given answer choice;

2x > 5 - x

Add x to both sides

2x + x > 5 - x + x

Simplify

3x > 5

Divide both sides by 3

[tex]\frac{3x}{3} > \frac{5}{3}[/tex]

x[tex]x=\frac{5}{3}[/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3 ( x - 4) [tex]\leq[/tex] - 23

[tex]3\left(x-4\right)\le \:-23\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-\frac{11}{3}\:\\ \:\mathrm{Decimal:}&\:x\le \:-3.66666\dots \\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-\frac{11}{3}]\end{bmatrix}[/tex]

Divide both sides by 3

[tex]\frac{3\left(x-4\right)}{3}\le \frac{-23}{3}[/tex]

Simplify

[tex]x-4\le \:-\frac{23}{3}[/tex]

Add 4 to both side

[tex]x-4+4\le \:-\frac{23}{3}+4[/tex]

Simplify

x [tex]\leq -\frac{11}{3}[/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3y-2 = 10

Add 2 to both sides

[tex]3y-2+2=10+2[/tex]

Simplify

[tex]3y=12[/tex]

Divide both sides by 3

[tex]\frac{3y}{3}=\frac{12}{3}[/tex]

Simplify

y = 4

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

a>13a+1

[tex]a > 13a+1\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:a < -\frac{1}{12}\:\\ \:\mathrm{Decimal:}&\:a < -0.08333\dots \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-\frac{1}{12}\right)\end{bmatrix}[/tex]

Subtract 13a from both sides

[tex]a-13a > 13a+1-13a[/tex]

Simplify

[tex]-12a > 1[/tex]

Multiply both sides by -1 (reverse the inequality)

[tex]\left(-12a\right)\left(-1\right) < 1\cdot \left(-1\right)[/tex]

Simplify

[tex]12a < -1[/tex]

Divide both sides by 12

[tex]\frac{12a}{12} < \frac{-1}{12}[/tex]

Simplify

[tex]a < -\frac{1}{12}[/tex]

Hence, Now you can infer that "3y-2=10" does not belong to the group.

what are cube roots of unity ??​

Answers

[tex]\huge\bold\red{₳₦₴₩ɆⱤ:-}[/tex]

The root of unity is a number which is complex in nature and gives 1 if raised to the power of a positive integer n. These roots are used in different branches and topics of maths like number theory. It is also called as de Moivre system.

What are Cube Roots of Unity?

There are a total of three cube roots of unity which are as follows:

Cube Root of Unity Value Nature of Cube Root

1 Real

−½ + i √(3/ 2) Complex

−½ – i √(3/ 2) Complex

Here, a = 1 is the real cube root of unity while a = – ½ + i √(3/ 2) and a = – ½ – i √(3/ 2) are the imaginary or complex cube roots of unity.

Find the sum of integers from 33 to 47

Answers

Answer: 600

Step-by-step explanation:

An integer simply means a particular number that's not a fraction or a decimal.

The sum of integers from 33 to 47 simply means:

= 33 + 34 + 35 + 36 + 37 + 38 + 39 + 40 + 41 + 42 + 43 + 44 + 45 + 46+ 47

= 600

Therefore, the sum of integers from 33 to 47 is 600.

In an effort to make childrenâs toys safer and more tamperproof, toy packaging has become cumbersome for parents to remove in many cases. Accordingly, the director of marketing at Toys4Tots, a large toy manufacturer, wants to evaluate the effectiveness of a new packaging design that engineers claim will reduce customer complaints by more than 10 percentage points. Customer satisfaction surveys were sent to 220 parents who registered toys packaged under the old design and 220 parents who registered toys packaged under the new design. Of these, 81 parents expressed dissatisfaction with packaging of the old design, and 41 parents expressed dissatisfaction with packaging of the new design.

Let p1 represent the population proportion of parents that expressed dissatisfaction with the packaging of the old design and p2 represent the population proportion of parents that expressed dissatisfaction with the packaging of the new design.

Required:
a. Specify the null and alternative hypotheses to test for whether the proportion of customer complaints has decreased by more than 5% under the new packaging design.
b. What is the value of the test statistic and the associated p-value?
c. At the 1% significance level, do the results support the engineers' claim?
d. At the 10% significance level, do the results support the engineers' claim?

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Old design samples(n1) = 220

New design samples (n2) = 220

P1 = 81/220 = 0.368 ; P2 = 41/220 = 0.186

Null hypothesis : p1 - p2 ≥ 0.05

Alternative hypothesis : p1 - p2 < 0.05

Using the test statistic formula :

t = (P1 - P2) / √[P(1-P)(1/n1 + 1/n2)]

P = (81 + 41)/(220 + 220) = 122/440 = 0.277

1 - P = 0.723

t = (0.368 - 0.186) / (√(0.277(0.723)(1/220 + 1/220)))

t = 4.265

P value from z test at α = 0.05

P value = 0.00002

Test for significance at α = 0.01 ;

Test for significance at α = 0.1

Result is significant at both α levels, hence reject the Null.

Answers

Answer:

4/11

Step-by-step explanation:

There are a total of 11 letters in the word Mississippi, so the denominator of the fraction will be 11. There are 4 of the letter S in Mississippi, so that will be the numerator.

The fraction is 4/11, and since 4 and 11 cannot be evenly divided it cannot be simplified.

The chances of choosing the letter S is 4/11
