Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

First we will go find the angle measure of 3.

We already know that <1 & <2 are 55° & 60°.

Tip: The sum of all the angles in a triangle is 180°.

So now if we add those two angles we'd get 115°, then we could subtract it from 180 to get the measure of <3, which is 65°.

For <4 it should be easier if you know that line AB is parallel to line CD and then line AC is the transversal because it goes through both lines.

Tip: Alternate interiors are angles that are equal to each other.

Then when you know all this you can figure out that <2 and <4 are alternate interiors which makes them equal to each other. So if they said that <2 is 60° then it'll only make sense if <4 is also 60°.

Now for <5 we know that <3,<4, and <5 are all on a line so that makes the sum of those three angles 180°.

So we would do the sum of <3, <4, then x and all that is equal to 180°.

[tex]65+60+x=180\\125+x=180\\x=55[/tex]

Great now we know <5 is 55°.

We will now move on to <6. It has the same relationship to <4 as <2 and <4. So if <4 is 60° that means <6 has to be 60°° as well.

Tip: The sum of these two angles (in this case are <5 and <6) are equal to t the outer angle (<7)

Now we have to figure out the measure of <7. First we have to notice that if we add <5 and <6 we will get <7. So 55 + 60 = 115 and that's it <7 is 115°.

Now the recap:

<3=65°

<4=60°

<5=55°

<6=60°

<7=115°

Answer:

Each term in marks pattern is 10 more than the corresponding term in joes pattern

Step-by-step explanation:

Given

Joe

[tex]Start = 18[/tex]

[tex]Additional = 3[/tex]

Mark

[tex]Start = 28[/tex]

[tex]Additional = 3[/tex]

Required

Determine which option answers the question

From the question, we have that Mark and Joe have the same additional rule of increment.

This implies that, the difference of each term is the same as the difference of the starting number of both:

Since Mark started at a higher number than Joe, the difference can be said to be.

[tex]Difference = Start_{Mark} - Start_{Joe}[/tex]

[tex]Difference = 28 -18[/tex]

[tex]Difference = 10[/tex]

Hence:

Answer:

a)P ( A∩S) =  0.116

b) P (x= 5) =0.272

c)  P (at most 5) = 0.950647

Step-by-step explanation:

Let A be an event that the  maize (modern-day corn) ears carry single spikelets and B be an event that the  maize carry paired spikelets.

Then P (B) = 60% = 0.6

P (A) = 1-P (b) = 0.4

Let S be the event that seed with single spikelets will produce an ear with single spikelets and Q be the event that seed with  paired spikelets will produce an ear with single spikelets .

Then

P (S) = 29% = 0.29

P (Q ) = 26% = 0.26

n= 10

We want to find out that exactly 5 single spikelets  seeds produce single spikelets .

P ( A∩S) = P(A) *P(S) = 0.4 * 0.29= 0.116

Now we have to find that exactly five of the ears produced by these seeds have single spikelets.

b) P (x= 5) =  P(A) *P(S)+  P(B) *P(R)

= 0.4 * 0.29 + 0.6 * 0.26

= 0.116+ 0.156= 0.272

At most five ears have single spikelets.This follows a binomial distribution where n is fixed and also p and q are same.

P ( x= at most 5) = 10C5 ( 0.116)^ 5(0.884)^5 +10C4 ( 0.116)^ 4(0.884)^6+10C3 ( 0.116)^ 3(0.884)^7+10C2 ( 0.116)^ 2(0.884)^8 +10C9 ( 0.116)^ 1(0.884)^9+10C10 ( 0.116)^ 0(0.884)^10    

=0.002857+0.018145+ 0.0000234+0.2558+ 0.3824+ 0.29144

= 0.950647

Answer:

b. form: p → q invalid, converse error q ∴ p

Step-by-step explanation:

Let

p = "there are as many rational numbers as there are irrational numbers,"

let

q = "the set of all irrational numbers is infinite."

We can write the above argument as:

If there are as many rational numbers as there are irrational numbers, then the set of all irrational numbers is infinite

p → q

The set of all irrational numbers is infinite

q

There are as many rational numbers as there are irrational numbers

p

So collectively it can be written as:

p → q

 q

∴p

So it looks like

if p then q

q

therefore p

This is a fallacious argument.  This means the conclusion can be false even when the premises are true. This type of argument is invalid.

Suppose we know that “If there are as many rational numbers as there are irrational numbers, then the set of all irrational numbers is infinite” is a true conditional statement. We also know that "the set of all irrational numbers is infinite" is true. This is not enough to say that "there are as many rational numbers as there are irrational numbers," is true. The reason for this is that there is nothing logically about “If p then q” and “q” that means p must follow. So this is a converse error and since converse error is an invalid method of inference rule so this argument is invalid.

Let us prove this argument is invalid with a truth table:

p   q   p → q   q   p

T   T      T       T   T

T   F      F       F   T

F   T      T       T   F

F   F      T       F   F

Since we know that the premises are:

p → q   and  q

and the conclusion is p

and an argument is valid if and only if all of its premises are true, then the conclusion is true. We should check that whenever both p → q   and  q are true then p is true but the third row fails. Thus this is an invalid argument.

Answer:

[tex] 5x - 1 = -6 [/tex]

[tex] x = -1 [/tex]

Step-by-step explanation:

The model above shows a weigh balance which can be represented by an equation have two sides, of which must be equal to each other.

On the right of the equation, we have 5 "x" and 1 "-", which can be represented as: [tex] 5x - 1 [/tex].

On the other side, we have 6 "-1", which can be represented as: -6.

The equation that can be used to solve x is:

[tex] 5x - 1 = -6 [/tex]

Solve for x. Add 1 to both side

[tex] 5x - 1 + 1 = -6 + 1 [/tex]

[tex] 5x = -5 [/tex]

Divide both sides by 5

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

[tex] x = -1 [/tex]

Answer:

Equation: 5x - 1 = -6

5 cant be simplified even down further unless it is a decimal or a fraction

Answer:

<A= right

<B= acute

<C= obtuse

<D=  right

Step-by-step explanation:

The number which is represented by the expression "five more than a certain number is 4 less than one-half that number" is -2/3

let

the unknown number = x

x + 5 = 4 - 1/2x

x + 1/2x = 4 - 5

1 1/2x = -1

x = -1 ÷ 3/2

= -1 × 2/3

= -2/3

Therefore, the number which is represented by the expression "five more than a certain number is 4 less than one-half that number" is -2/3

The Operating income is $172,500.

To calculate the margin of safety, contribution margin ratio, and operating income, we need to use the given information.

a. Margin of Safety:

Margin of Safety = Actual Sales - Break-even Sales

Given that the break-even point is at $750,000 in sales revenue and actual sales are $1,100,000, we can calculate the margin of safety:

Margin of Safety = $1,100,000 - $750,000 = $350,000

Therefore, the margin of safety is $350,000.

b. Margin of Safety as a Percentage of Sales:

Margin of Safety Percentage = (Margin of Safety / Actual Sales) * 100

Using the values from the previous calculations:

Margin of Safety Percentage = ($350,000 / $1,100,000) * 100 = 31.82%

Therefore, the margin of safety expressed as a percentage of sales is approximately 31.82%.

c. Contribution Margin Ratio:

Contribution Margin Ratio = (Contribution Margin / Sales) * 100

To calculate the contribution margin, we need to subtract variable costs from sales:

Contribution Margin = Sales - Variable Costs = $1,100,000 - $645,000 = $455,000

Using the values, we can calculate the contribution margin ratio:

Contribution Margin Ratio = ($455,000 / $1,100,000) * 100 = 41.36%

Therefore, the contribution margin ratio is approximately 41.36%.

d. Operating Income:

Operating Income = Sales - Variable Costs - Fixed Costs

Using the values provided:

Operating Income = $1,100,000 - $645,000 - $282,500 = $172,500

Therefore, the operating income is $172,500.

Answer :

Part 17: The value of x is 5.

Part 18: The value of x is 2°.

Step-by-step explanation :

Part 17:

Given:

Length SR = 2x - 9

Length RQ = x + 6

Length SQ = 12

Now we have to determine the value of x.

Length SQ = Length SR + Length RQ

12 = (2x - 9) + (x + 6)

12 = 2x - 9 + x + 6

12 = 3x - 3

3x = 15

x = 5

The value of x is 5.

Part 18:

Given:

∠MLK = 81x - 2

∠HLK = 54x + 2

∠MLH = 50°

Now we have to determine the value of x.

∠MLK = ∠HLK + ∠MLH

81x - 2 = 54x + 2 + 50°

81x - 2 - 54x - 2 = 50°

27x - 4 = 50°

27x = 54°

x = 2°

The value of x is 2°
