The number of months (m) your parents will spend paying for the phone, and then x≤11, by solving the inequality.

Therefore,

Set the months to X based on the information from the query, and we have

35X + 100 ≤ 485

then we can have

35x ≤ 485 -100

35x≤385

x≤385/35

x≤11

Consequently, we may state that the parents will pay for the phone for a total of 11 months.

The probability is the likelihood that anything will happen, and in November, the probability of receiving a diamond or a 7 is 1/39.

Simply put, the probability is the likelihood that something will occur.

When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.

Statistics is the study of events that follow a probability distribution.

Probability is a measure of how likely something is to occur.

The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur.

So, in 52 cards, there are 13 diamonds and 4 sevens ( one of 7 included in 13 diamonds)

Getting a 7 or a diamond:  (13 + 4 - 1) /52 = 16 / 52 = 4 / 13

November: 1 / 12

4 / 13 * 1 / 12 = 4 / 156 = 1 / 39

Therefore, the probability is the likelihood that anything will happen, and in November, the probability of receiving a diamond or a 7 is 1/39.

Therefore , the solution of the given problem of deviation comes out to be

MAD mean = 1.55.

The difference between their means can be estimated by subtracting it from the mean absolute deviation of the two datasets.

The average distance between each data value and the mean is known as a collection of data's mean absolute deviation (MAD).

Here,

Given :

=> Previous year : 46.8 in. with a MAD of 1.5 in

=> Last year :  49.9 in. with a MAD of 1.6 in.

=>Mean = 46.8 +49.9 /2 = 48.35

=> MAD mean = 1.5 + 1.6 = 1.55

The average of each point's "positive distances" from the mean is the mean absolute deviation. The degree of data variability increases with the MAD (the data is more spread out).

Each digit in the data set should be taken, the mean subtracted, and the absolute value calculated. Take the total of the absolute values next. Next, divide the aforementioned sum by the total number of values in the data set to obtain the mean absolute deviation.

The equation of the circle with a center at the point (-7,8) and a radius of 4 units is (x + 7)² + (x - 8)² = 16.

The standard form of a circle with a center at (h,k) and a radius r is

(x - h)² + (x - k)² = r².

Since we have center as a point A which is (-7,8) and radius of circle as 4 units ,

h = -7

k = 8

r = 4

Thus the equation of circle is,

(x -(-7))² + (x - 8)² = 4²

This equation simplifies to be ,

(x + 7)² + (x - 8)² = 16

A circle is a two-dimensional object made up of points that are spaced out from a given point (centre) on the plane by a fixed or constant distance (radius). The fixed point is referred to as the circle's origin or center, and the fixed distance between each point and the origin is referred to as the radius.

The standard deviation of the probability distribution for the given price of each doughnut and the variance is equal to $√1.50 × 3.6.

Price of the each doughnut 'P' = $1.50

Expected value of the probability distribution of the doughnut = 2.6

Variance of the probability distribution = 3.6

Price of the variance of the probability distribution is equal to

= Price of each doughnut × Variance

= 1.50 × 3.6

Standard deviation of the probability distribution is equal to

= √ Price of the variance of the probability distribution

Answer:

x = 11 , TB = 12 cm

Step-by-step explanation:

given a tangent and a secant from an external point to the circle, then

the square of the measure of the tangent is equal to the product of the measures of the secant's external part and the entire secant, that is

TC × TB = TA²

3(3 + x - 2) = 6²

3(x + 1) = 36 ( divide both sides by 3 )

x + 1 = 12 ( subtract 1 from both sides )

x = 11

then

TB = TC + CB = 3 + (11 - 2) = 3 + 9 = 12 cm

Answer:

Step-by-step explanation:

The equation of the line can be found using the point-slope form:

y - y1 = m (x - x1)

where m is the gradient, (x1, y1) is a point on the line.

For the given information:

m = 3, x1 = -1, y1 = 3

Plugging in the values into the point-slope form:

y - 3 = 3 (x - (-1))

Simplifying the equation:

y = 3x + 6

So, the equation of the line is: y = 3x + 6

The value for the unknow x cannot be equal to 10.

The value of x in the first equation is not equal to 10. To see this, we can substitute x = 10 into the equation:

125 < 12 * 10 = 120

Since 125 is not less than 120, the inequality is false when x = 10. Therefore, x cannot be equal to 10.

A simultaneous equation is a set of two or more equations that contain two or more variables, and all the equations in the set are solved together to find the values of the variables.

Simultaneous equations can be represented graphically as intersecting lines or curves in a coordinate plane. The solution to a set of simultaneous equations is a set of values for the variables that satisfies all the equations in the set.

The sum of the first K numbers is (K * (K + 1)) / 2

For the first K odd numbers, the formula is K^2

First K numbers

The formula (K * (K + 1)) / 2 represents the sum of the numbers from 1 to K,

This is so because it counts the total number of dots in the triangle (K * (K + 1)) and then divides by 2 to account for double-counting the dots in the middle row.

So, we have

Sum = (K * (K + 1))/2

Odd numbers

For the sum of the first K odd numbers, we can use the formula K^2.

This formula works because odd numbers can be represented as (2n - 1), where n is a positive integer.

So, the first K odd numbers can be represented as

(2 * 1 - 1) + (2 * 2 - 1) + ... + (2 * K - 1).

Step-by-step explanation:

a scientific number like 8.14 × 10^-7 is simply a form of

a × b

all operations with scientific numbers base on this.

multiplication :

(a × b) × (c × d) = a × b × c × d

or any other combination, as multiplication is commutative.

e.g. a × c × b × d

if it helps with a better understanding and the combination of factors of the same base.

addition :

(a × b) + (c × d)

this cannot be simplified per se.

we need to bring factors of both terms to the same base in order to be able to add them.

so,

part A

the area of a rectangle is

length × width

so, we have

8.14 × 10^-7 × 3.6 × 10^-9

as explained above, to make this better visible we combine factors of the same base :

8.14 × 3.6 × 10^-7 × 10^-9

remember, when multiplying factors of the same base, we simply add the exponents :

10^-7 × 10^-9 = 10^(-7 + -9) = 10^-16

and

8.14 × 3.6 = 29.304

so, the total result is

29.304 × 10^-16 m²

part B

a scientific number has exactly one significant digit (not 0) in front of the decimal point, and all other significant digits after the decimal point.

so, what do we need to convert

29.304 × 10^-16

to that ?

we need to divide the left part by 10. but to keep the value of the total number unchanged, we then need to multiply the right part by 10. in other words, we multiply by 10/10.

and we get

2.9304 × 10^-15 m²

part C

the perimeter of a rectangle is

2×length × 2×width

2×8.14×10^-7 + 2×3.6×10^-9

the first step is easy : simplifying the multiplications by 2.

16.28×10^-7 + 7.2×10^-9

now, we can only add them, if there is the same factor in each term.

and the easiest way to get to that is a manipulation of the 10-factors.

let's bring 10^-7 to 10^-9. that means a division by 100. remember, we need to keep the overall value of the number. what, what we do to one factor we need to counter in the other factor :

16.28×10^-7 = 100/100 × 16.28×10^-7 =

= 100×16.28 × (10^-7)/100 =

= 1628 × 10^-9

now we can add both numbers

1628×10^-9 + 7.2×10^-9 = 1635.2×10^-9 m

part D

remember what we said in part B.

here now we need to divide the left part by 1000. which means we also need to multiply the right part by 1000.

1635.2×10^-9 × 1000/1000 = 1.6352 × 10^-6 m
