We are also given the box plot diagram of the data which shows that:

Minimum value of the data = 74

Lower quartile = 83

Median quartile = 86.5

Upper quartile = 92.75

Maximum value = 99

We need to tell which is the wrong interpretation among these.

We can see that, the maximum value of the data is only 93 and not 99.

Ari loss 53.94% of his account balance for this live tv streaming service.

Given,

The charge for a live tv streaming service that is automatically deducted from Ari's bank account each month = $8.99

This deduction continues for 6 months.

We have to find the change in Ari's bank account after 6 months for this service.

Charge for 1 month = 8.99

Charge for 6 months = 6 × 8.99 = 53.94

That is if Ari had $100 in his account, now after 6 months 53.94% deducted for the tv streaming service charge.

Now, he has an account balance:

100 - 53.94 = 46.06

In terms of amount, he has an account balance of $46.06.

In terms of percentage,

Ari lost 53.94% from his account balance and now he has 46.06% account balance.

So, x is equal to  [tex]\sqrt{1/2}[/tex]

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

Definition of a perfect square-A number system that can be stated as the square of a specific number from the same system is called a perfect square.Assume that N may be expressed as the product of x and x = x²,if x is a perfect square of a number N. Square roots can be used to understand this in another way. We compute the square root of a given number to determine if it is a perfect square or not. The supplied number is a perfect square if the square root is a whole number.However, if the square root value is not a whole number, the given number is not a perfect square.Now according to given question we have to find sum of all the positive inetegers between √14 to √80

Answer:

I Disagree with Peter, the explanation is down below.

Step-by-step explanation:

I disagree because to find the least common multiple or the LCM, you need to first list the first several multiples of each number. So, because the numbers are 4 and 6, I would write:

4 - 4, 8, 12, 16, 20, 24, 28, 32

6 - 6, 12, 18, 24 30, 36, 42, 48

The next step would be to find the same multiples in the list. If there are no same multiples, then I would keep on adding multiples.

If we look at the list, the first numbers that we see that are the same are 12 and 12.

12 would be the LCM, not 24.

If the two numbers were 24 and 12, then the LCM would have been 24, but in this case, the LCM is 12. So that is why I disagree.

Let us organize the information first. The game consists in picking up a numbered duck. Let us denote the number of the duck as xx. The possible prizes are

1≤ x≤ 60 consolation prize

60 ≤ x ≤ 70 stuffed duck

70≤ x ≤ banana

We have 75 possible numbers equally likely to select, and 1111 outcomes where we win the stuffed duck

60, 61, 62, 63, 64, 65, 66, 67, 68, 69 and 70

Therefore, the probability of winning a stuffed duck is

p(60 ≤ x ≤ 70) = 11/75= 0.146

The event of not winning a duck or a banana is that of winning the consolation prize, that is, picking a number 1 ≤x ≤ 60.

Those are 59 equally likely to occur outcomes. Then we have

c= 59/75= 0.786

To check whether this result is right, we can use the complementary events law. That is, the probability of not winning a duck or a banana is 11 minus the sum of the probabilities of winning a duck or a banana. Mathematically this is

p (1 ≤ x ≤ 60) = 1-(p (60≤x≤70)+p(70≤x≤75)

p (1≤ x ≤ 60) = 0.786

which is a desired result.

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.

For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0. Similarly, the additive inverse of a − b is −(a − b) which can be simplified to b − a. The additive inverse of 2x − 3 is 3 − 2x, because 2x − 3 + 3 − 2x = 0.

Formula to find compound interest is:

T = time for which the amount is invested

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest.

It is thought that Italy in the 17th century is where the concept of "interest on interest" or compound interest first appeared. It will accelerate the growth of a total more quickly than simple interest, which is solely calculated on the principal sum.

Step-by-step explanation:

for the lengths of BC and AC we can count the squares, because the lengths of these lines are the sum of the side lengths of each inducing square.

1.

BC = 7 - -2 = 7 + 2 = 9 cm

2.

AC = 13 - 1 = 12 cm

3.

but for AB we cannot do that, because AB consists of the lengths of all the diagonals of the squares. and a diagonal must always be longer than any side.

just look at the triangle : it is clear that AB must be longer than AC.

no, for a line that goes across the grid squares we need other methods.

in our case, we have a right-angled triangle and can use Pythagoras

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle), a and b being the legs of the triangle (enclosing the 90° angle).

AB is in our case the Hypotenuse, and we get

AB² = 12² + 9² = 144 + 81 = 225

AB = sqrt(225) = 15 cm

4.

as explained, we used Pythagoras.

5.

the coordinates for a midpoint between 2 points (x1, y1) and (x2, y2) are simply

((x1+x2)/2, (y1+y2)/2)

A = (13, -2)

B = (1, 7)

C = (1, -2)

midpoint AC = ((13+1)/2, (-2 + -2)/2) = (14/2, -4/2) =

= (7, -2)

the x coordinate is 7.

6.

midpoint BC = ((1+1)/2, (7+ -2)/2) = (2/2, 5/2) = (1, 2.5)

the y coordinate is 2.5

7.

midpoint AB = ((13+1)/2, (-2+7)/2) = (14/2, 5/2) =

= (7, 2.5)

The value of the expression log₂9 after using change of base theorem is 3.17.

Given that the expression be log₂9.

We are required to find the value of the expression by finding the value of log values.

Change of base formula is basically used in a situation where we have to solve the log values with different bases at one time. It says that

[tex]log_{a}b[/tex]=[tex]log_{x}b/log_{x}a[/tex].

The expression is  log₂9.

We know that [tex]log_{b}a[/tex]=log a/log b.

log₂9=log 9/log 2

Now,we have to use the values of log in the above expression.
