Answer:

Both processes will yield same results and he need not worry

Step-by-step explanation:

Let us firstly check if we will have same results on both steps

y before x

Let us have the point (x,y) on the triangle

y reflection

(-x,y)

then x reflection

(-x,-y)

Let us now get the order in which my friend followed

x reflection

(x, -y)

y reflection

(-x,-y)

we can see that both processes have same results and thus, my friend need not worry

Answer:

The order of these two reflections  

does not

matter. The resulting image  

is

the same for a reflection in the y-axis followed by a reflection in the x-axis as for a reflection in the x-axis followed by a reflection in the y-axis.

Answer:

A) 0.48

Step-by-step explanation:

The probability that Mrs. Barnes does not check homework if the students take a pop quiz will be 0.77.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Mrs. Barnes’s class determined the probability that she will check homework on a randomly chosen day is 0.42.

They also determined the probability that she will give a pop quiz when she checks homework is 0.6, and the probability that she will give a pop quiz when she does not check homework is 0.9.

Then the probability that Mrs. Barnes does not check homework if the students take a pop quiz will be =

P = 0.42 x 0.6 + 0.58 x 0.9

P = 0.252 + 0.522

P = 0.774 ≈ 0.77

Answer:

x=y=z=90.

Step-by-step explanation:

let the 3 numbers be x,y,z.

let s be sum

s=x+y+z

we need to maximize xy+yz+zx

or , xy + y(270-(x+y))+x(270-(x+y)) = P(x)

Use Lagrange's Multipliers

⇒ΔP= λΔS

⇒[tex]\frac{x+y}{x+z} =1[/tex]

⇒y=x

⇒\frac{x+z}{x+y} =1

⇒z=y

⇒x=y=z

⇒3x = 270

⇒x= 90

hence, x=y=z=90.

C. ECA = BDA

Step-by-step explanation:

An angle is said to be produced whenever two or more lines meet at a point. An interior angle is an angle form within two lines meeting at a point. Then, alternate interior angles are internal angles that are equal due to alternate theorem. These angles should have equal measures.

From the given question, the alternate interior angles by the theorem is;

ECA = BDA

By the alternate interior angle theorem, the alternate interior angles are ECA and BDA. This implies that the measure of <ECA should be equal to the measure of <BDA.

Step-by-step explanation:

It’s half

Answer:

gₙ = gₙ₋₁ + 0.4, with g₁ = 6.4

Step-by-step explanation:

The n-th term of an arithmetic sequence can be written as:

gₙ = g₁ + (n - 1)*d

Where g₁ is the first value, and d is the difference between any two consecutive terms of this sequence.

Then we have the equations:

g₅ = 8 = g₁ + (5 -1)*d

g₁₀ = 10 = g₁ + (10 - 1)*d

This is a system of equations, we can rewrite this as:

8 = g₁ + 4*d

10 = g₁ + 9*d

To solve this, the first step will be isolate one of the variables in one of the equations, i will isolate g₁ in the first equation:

g₁ = 8 - 4*d

Now we can replace this in the second equation to get:

10 = 8 - 4*d + 9*d

10 = 8 + 5*d

10 - 8 = 5*d

2 = 5*d

2/5 = d = 0.4

Now with this, we can find the value of g₁ by using the equation:

g1 = 8 - 4*d = 8 - 4*(2/5) = 8 - 8/5 = 6.4

Then the nth term of this sequence can be written as:

gₙ = 6.4 + (n - 1)*0.4

This relation also can be written as:

gₙ = gₙ₋₁ + d = gₙ₋₁ + 0.4, with g₁ = 6.4

Then the correct option is the second option.

Answer:

she did not get at least 2100 and definitely not 85% of the worth

Step-by-step explanation:

3000*0.85=2550

3000*0.7=2100

Answer:

Gia hoped to sell it for $2,550, but wanted at least $2,100. Because it sold for $1,800, she did not get what she hoped and/or wanted.

Step-by-step explanation:

85% of $3,000 can be solved by moving the decimal two places to the left and multiplying: 85.0% becomes 0.85. So, we multiply 0.85x3,000=$2,550.

We do the same thing to figure out 70% of $3,000. Again, solving it by moving the decimal two places to the left and multiplying: 70.0% becomes 0.70. So, we multiply 0.70x3,000=$2,100.

Answer:

5

Step-by-step explanation:

∆FGH is similar to ∆JKH. Therefore, their corresponding lengths are proportional to one another. Thus:

[tex] \frac{GH}{KH} = \frac{FH}{JH} [/tex]

GH = x + 15

KH = x

FH = 12 + 4 = 16

JH = 4

Plug in the values

[tex] \frac{x + 15}{x} = \frac{16}{4} [/tex]

Cross multiply

[tex] (x + 15) \times 4 = 16 \times x [/tex]

[tex] 4x + 60 = 16x [/tex]

Subtract 4x from each side

[tex] 60 = 16x - 4x [/tex]

[tex] 60 = 12x [/tex]

Divide both sides by 12

x = 5

KH = x = 5

Answer:

Step-by-step explanation:

that's your answer:)

Answer:

Step-by-step explanation:

From the diagram, we can se that line l is parallel to m. This means that according to geometry, m<7 and m<9 are located on the same position on line n. Hence m<7 = m<9 (corresponding angle)

Given

m<7 = 9x+ 5

m<9 = x+37

Equaling both

9x + 5 = x+ 37

9x - x = 37-5

8x = 32

x = 32/8

x = 4

Hence the value of x is 4

Step-by-step explanation:

1. Find the amount of money Caroline saved

Original - spent

Subsitute in the given values,

64 - 56.32 = 7.68

2. Set up a proportion

A proportion is

[tex]\frac{part}{whole} = \frac{percent}{100}[/tex]

Substitute in the values;

[tex]\frac{7.68}{64}=\frac{percent}{100}[/tex]

Cross products;

(7.68)(100) = (64)(percent)

768 = 64 * percent

Inverse operations;

768 = 64 percent

/64      /64

12 = percent

Caroline had a 12% discount.

Answer:

25l+20d=x and x ≤ 2000 needs to be part of the system.

Step-by-step explanation:

Given that:

Amount charged per lawn = $25

Number of lawns = l

Amount charged per driveway = $20

Number of driveways = d

Amount saved by Jamison = x

[tex]25l+20d=x[/tex]

Amount given by parents = upto $2000

It means the parents will not give more money than $2000, therefore, we will use less than equal to inequality

x ≤ 2000

Hence,

25l+20d=x and x ≤ 2000 needs to be part of the system.

Answer:

-0.0423≤p≤0.0977

Step-by-step explanation:

The margin error formula is expressed as;

ME = p±√p(1-p)/n

n is the sample size

For the first population proportion p1:

p1 = 193/558 = 0.3469

n1 = 558

p2 = 196/614 = 0.3192

n2 = 614

Taking the difference in the confidence of the proportion

p = p1-p2

p = 0.3469-0.3192

p= 0.0277

Get the margin of error

Margin of error = z*√p(1-p)/n

Margin of error = 2.5758*√0.35(1-0.35)/558 + 2.5758*√0.32(1-0.32)/614

Margin of error = 2.5758*√0.35(0.65)/558 + 2.5758*√0.32(0.68)/614

Margin of error = 2.5758*(0.02019)+2.5758(0.0188)

Margin of error = 0.07

Get the confidence interval

CI = p±ME

CI = (p-ME, p+ME)

CI = (0.0277-0.07, 0.277+0.07)

CI = (-0.0423, 0.0977)

Hence a 99% confidence interval for the difference between the two population proportions is -0.0423≤p≤0.0977

Answer:

Your total monthly payment would be; 1,500 dollars.

Monthly Rent means the monthly installments of the Annual Minimum Rent and the estimated annual utility bills payable by the Lessee under this Rental Agreement.

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

We are given that  You have a gross lease of $1,000 per month. Also, Taxes and maintenance total $500 per month.

we need to calculate the your total rent payment.

Therefore, we know that;

Rent= base payment + percent of revenue

       = 1,000 + 500

       = 1500

Hence, we can conclude that the monthly rent should be 1500 dollar.
