Answer:

The median is known as a measure of location; that is, it tells us where the data are. As stated in , we do not need to know all the exact values to calculate the median; if we made the smallest value even smaller or the largest value even larger, it would not change the value of the median. Thus the median does not use all the information in the data and so it can be shown to be less efficient than the mean or average, which does use all values of the data. To calculate the mean we add up the observed values and divide by the number of them. The total of the values obtained in Table 1.1 was 22.5

Answer:

Angle A= 61°

Step-by-step explanation:

angle A+ Angle B+Angle C= 180°( Angle sum property)

∠A+57+72= 180°

∠A= 180°- 127°= 61°

kong: 15% 15x100=1,500

Nolan:85 seconds 85x2=170

then when you multiple kong by 15 and 100 it gives you 1,500 however nolan did of the seconds 85x 2 gives you 170 . in conclusion Nolan did 15x2=30 . which means Nolan did 30 seconds.

Answer:

Step-by-step explanation:

Let's start with the expression 1/(1+i). It is simplified by multiplying numerator and denominator by its conjugate.

  [tex]\dfrac{1}{1+i}=\dfrac{1-i}{(1+i)(1-i)}=\dfrac{1-i}{2}[/tex]

Subtracting this from 1, as in the denominator inside parentheses, gives its conjugate.

  [tex]1-\dfrac{1-i}{2}=\dfrac{1+i}{2}[/tex]

__

The 5th power can be found a couple of ways. One is to use the binomial expansion. Another is to use Euler's formula. The latter can be somewhat easier.

  [tex]\dfrac{1-i}{2}=\dfrac{1}{\sqrt{2}}\angle-\!45^{\circ}\\\\\left(\dfrac{1-i}{2}\right)^5=\dfrac{1}{\sqrt{2^5}}\angle(5(-45^{\circ}))=\dfrac{1}{4\sqrt{2}}(\cos(135^{\circ})+i\sin(135^{\circ}))\\\\=\dfrac{1}{8}(-1+i)[/tex]

With these parts, we can now write the first expression as ...

[tex]\displaystyle\frac{A}{i+i}\left(\frac{1-(\frac{1}{1+i})^5}{1-(\frac{1}{1+i})}\right)=A\left(\frac{1-i}{2}\right)\left(\frac{1-\frac{-1+i}{8}}{\frac{1+i}{2}}\right)=\frac{A}{8}\cdot\frac{1-i}{1+i}\cdot(9-i)\\\\=\frac{A}{8}\cdot\frac{(1-i)^2(9-i)}{1^2-i^2}=\frac{A(-2i)(9-i)}{8\cdot2}=\boxed{-A\frac{(1+9i)}{8}}[/tex]

__

Using the same parts, we can simplify the second expression.

  [tex]\displaystyle\frac{A}{i}\left(1-\left(\frac{1}{1+i}\right)^5\right)=\frac{A}{i}\cdot\frac{(9-i)}{8}=\frac{A(9-i)(i)}{8i^2}=\boxed{-A\frac{(1+9i)}{8}}[/tex]

Answer:

no cap -check ur test thingy i got the answer from yahoo asks its x^2+6x+5

Step-by-step explanation:

Answer:

(4) 25​

Step-by-step explanation:

First, find the slope using rise over run:

(y2 - y1) / (x2 - x1)

Plug in the points:

(11 - 5) / (3 - 0)

6 / 3

= 2

The y intercept, (0, 5), has already been given. Using the equation y = mx + b, plug in the slope and y intercept to create the equation:

y = mx + b

y = 2x + 5

Now, plug in 10 as x to find the value of y:

y = 2x + 5

y = 2(10) + 5

y = 20 + 5

y = 25

So, the correct answer is answer choice 4, 25.

The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

A line passes through points (0,5) and (3, 11). Then the equation of the line is given as,

(y - 5) = [(11 - 5) / (3 - 0)](x - 0)

y = 2x + 5

If the value of the variable 'x' is 10, then the value of the variable 'y' is calculated as,

y = 2(10) + 5

y = 20 + 5

y = 25

The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.

Answer:

.83

Step-by-step explanation:

In order to find the probability that either a boy or an A student is chosen, you must first identify how many boys and A students there are altogether in the class:

9 boys who are not A students + 8 boys who are A students + 12 girls who are A students = 29 students are either boys or A students

Now, you just need to turn this into a probability:

1: 29/35 (given)

2: ≈82.86/100 (multiply both the numerator and denominator by 100/35)

3: ≈83% or .83 (round to the ones place and turn into a decimal)

Answer:

d = 0.277 km

Step-by-step explanation:

Distance covered in January = 0.5² km

The distance covered in February = 0.3³ km

We need to find the total distance he swam for both months. It can be calculated by finding their sum. So,

[tex]d=0.5^2+0.3^3\\\\d=0.25+0.027\\\\d=0.277\ km[/tex]

So, he swam 0.277 km for both months. Hence, the correct option is (b).

Step-by-step explanation:

The computation of the gits is shown below;

Given that

The ribbon which is used to wrap the gift = 1.2m

The ribbon that he spoiled = 18feet

based on the above information

As we know that 3feet = 1m

1foot = 1 ÷ 3 m

Now

18feet = 1 ×18 ÷ 3

18 feet = 6m

Now,

gift can be packed = 6 ÷ 1.2

= 60 ÷ 12

Step-by-step explanation:

We can buy 10 gallons of gas with $30, whose unit price is $2.85.

The rate calculated for one quantity of something is called unit rates.

Given that, the gas costs $2.85 per gallon, we need to find how many whole gallons of gas could you buy with $30.00.

Let the x gallons cost $30.00

Therefore,

2.85x = 30

x = 30 / 2.85

x = 10.52

x ≈ 10

Hence, we can buy 10 gallons of the gas from $30.
