Square A is a dilation of Square B. What is the scale factor?

Answer:

- 7/48, decimal form 0.145 and 17

Step-by-step explanation:

About 1407 sharks would be needed to have a margin of error of 0.25

Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:

[tex]E=Z_\frac{\alpha}{2} *\frac{standard\ deviation}{\sqrt{sample\ size} }[/tex]

The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:

[tex]0.25=1.645*\frac{5.7}{\sqrt{sample\ size}}\\ \\sample\ size=1407[/tex]

Explaination:

This problem can be represented by the equation: (7/3)=(x/15) Then solve for x, which is 35.

Amul can paint 35 chairs   in 15 hours

Let the number of chairs Amal can paint be represented as N

And amount of time she spends painting be represented as t

such that

The number of chairs Amal can paint varies directly with the amount of time she spends painting will be expressed as

N∝t

Introducing the constant of proportionality,K becomes

N=Kt

Amal can paint 7 chairs in 3 hours.K becomes

N=Kt

7=K3

K=7/3

Now if Amul paint in 15 hours, she would paint

N=Kt

N=7/3 X 15

N=35 Chairs

Answer:

H₀: µ = 1100 vs. Hₐ: µ ≠ 1100.

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.  

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.

Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.

The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.

It is also known as the research hypothesis and is denoted by Hₐ.

In this case the hypothesis can be defined as follows:

Null hypothesis:

H₀: The average calorie intake of a diner at this restaurant is 1100, i.e. µ = 1100.

Alternate hypothesis:

Hₐ: The average calorie intake of a diner at this restaurant is different from 1100, i.e. µ ≠ 1100.

Answer:

Alright, for question 7, the angle pair relationship is that they are corresponding angles.

So, 17x - 34 = 13x - 14. This means that 4x = 20, and x = 5 :)

For question 8, the angles are a linear pair. They are supplementary (adding to 180) :)

So, 37x - 17 + 33x - 13 = 180

This means taht 4x = 210, and x = 52.5? (I'm not sure if I screwed up on the arithmetic on this one, please correct if you find any mistakes!)

Answer:

  a) payment: $1082.84

  b) interest: $194,822.40

Step-by-step explanation:

The monthly payment on the mortgage can be found using the given formula with the given values of principal (P=195000), interest rate (r=0.053), and time period (t=30). The value of n is 12, corresponding to the number of months in a year.

The monthly payment is ...

  [tex]k=\left(1+\dfrac{r}{n}\right)^{nt}=\left(1+\dfrac{0.053}{12}\right)^{12\cdot30}\approx 4.88661119\\\\\text{monthly payment}=\dfrac{P\cdot\dfrac{r}{n}\cdot k}{k-1}=\dfrac{195000\cdot0.0044166667\cdot4.88661119}{4.88661119-1}\\\\\boxed{\text{monthly payment}=\$1082.84}[/tex]

__

The interest owed is the difference between the total of monthly payments and the principal of the loan:

  interest owed = (360)(1082.84) -195000 = 194,822.40

The interest owed over 30 years is $194,822.40.

collect variables in one side

[tex]\sf 7y -9y +4y = 13 +4[/tex]

simplify by addition and subtraction

[tex]\sf 2y = 17[/tex]

divide both sides by 2

Hence, ,final answer:

[tex]\sf y = \dfrac{17}{2}[/tex]

Answer:

A.   y = 17/2

Step-by-step explanation:

Given equation:

7y - 4 = 9y + 13 - 4y

Collect like terms:

7y - 4 = 9y - 4y + 13

Combine like terms:

7y - 4 = 5y + 13

Subtract 5y from both sides:

2y - 4 = 13

Add 4 to both sides:

2y = 17

Divide both sides by 2:

y = 17/2

Answer:

The weight of pure gold in 10 grams of 20 carat it is given that 24 carat gold is cent percent pure gold is 83.33 grams.

Step-by-step explanation:

To find : The weight of pure gold in 10 grams of 20 carat it is given that 24 carat gold is cent percent pure gold ?

Solution :

[tex]y(x)=\frac{1}{2}e^{-3x}-\frac{2}{3}e^{-2x}+\frac{1}{6}e^{x}[/tex]

Step-by-step explanation:

[tex]y''+y'-2y=e^{-3x},\: y(0)=0,\: y'(0)=0\\\\\mathcal{L}\{y''\}+\mathcal{L}\{y'\}-2\mathcal{L}\{y\}=\mathcal{L}\{e^{-3x}\}\\\\s^2Y(s)-sy(0)-y'(0)+sY(s)-y(0)-2Y(s)=\frac{1}{s+3} \\ \\s^2Y(s)+sY(s)-2Y(s)=\frac{1}{s+3}\\ \\(s^2+s-2)Y(s)=\frac{1}{s+3}\\ \\Y(s)=\frac{2}{(s+3)(s^2+s-2)}\\ \\Y(s)=\frac{2}{(s+3)(s+2)(s-1)}[/tex]

Perform the partial fraction decomposition

[tex]\frac{2}{(s+3)(s+2)(s-1)}=\frac{A}{s+3}+\frac{B}{s+2}+\frac{C}{s-1}\\ \\2=(s+2)(s-1)A+(s+3)(s-1)B+(s+2)(s+3)C[/tex]

Solve for each constant

[tex]2=((-2)+2)((-2)-1)A+((-2)+3)((-2)-1)B+((-2)+2)((-2)+3)C\\\\2=-3B\\\\-\frac{2}{3}=B[/tex]

[tex]2=(1+2)(1-1)A+(1+3)(1-1)B+(1+2)(1+3)C\\ \\2=12C\\\\\frac{2}{12}=C\\ \\\frac{1}{6}=C[/tex]

Answer:

y=252/5=50.4

Step-by-step explanation:

[tex](A)\ 9y-252=4y\\(B)\ 5y=252\\(C)\ y= \frac{252}5 = 50.4[/tex]

In step A we multiplied both sides by the least common multiple of the denominators, in order to deal with only integers for as long as possible.

In step B you subtract 4y and add 252 to both sides ("moving them on the other end of the equal sign").

In step C you finally divide by 5 to isolate y.

Answer:

9

Step-by-step explanation:

this is because it is 9 and it could be 9

Answer:

First let's find what (5x7) + (5x9) equals;

(5x7) + (5x9)

35 + 45

= 80

Now 80 has to equal to;

5 x (7 + y) ( where 'y' is our unknown number)

So we set up the equation:-

80 = 5 x (7 + y)

80 = 35 + 5y

-35      -35

45 = 5y

/5    /5

9 = y

Let's double check:

80 = 5 x (7 + y)

80 = 5 x (7 + 9)

80 = 35 + 45

80 = 80, we are correct.
