We get the repeated addition as ( - 4 ) + ( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ).
We are given a multiplication expression:
( + 7 ) ( - 4)
We need to write this expression as a repeated addition
Repeated addition means when we add the same digits many times that is repeatedly.
For example: 3 + 3 + 3 + 3 or 8 + 8 + 8 + 8 or 5 + 5 + 5 +5 etc.
Here, we can see that -4 is multiplied by 7
It means that - 4 will be added 7 times repeatedly to form the expression
So, we get that:

If, we invested $2,800 at a 6% annual interest rate. We will have $2972.70 in 1 year and $3063 in 1.5 year of time.
What is interest?In the fields of finance and economics, interest is defined as the payment of a sum over and above the principal amount (the amount borrowed) at a set rate by a borrower or deposit-taking financial institution to a lender or depositor. It is different from a fee that the borrower may pay to the lender or another entity. It also differs from a dividend, which is money given to shareholders (owners) by a company from its profit or reserve, but not at a set rate predetermined beforehand, but rather on a pro rata basis as a portion of the rewards received by risk-taking businesspeople when revenue is earned that exceeds all costs.
Calculations:
The Future value= fv= Pv x [tex](1+r/m)^{mt}[/tex]
R= Rate per period
mt= years x compounding

find the gradient-intercept form of the equation of the line which has a gradient of 5 and passes through the point (1, 11)
The gradient-intercept form of the equation of the line which has a gradient of 5 and passes through the point (1, 11) is y = 5x + 6
Gradient intercept form Or slope incept form of a linear equation is given by
y = mx + c
where m is the gradient or slope of the equation and c is the constant
As we are aware that the line passes through a point whose coordinates are (1, 11)
By putting the value of gradient/ slope, x coordinate in place of x in equation and y coordinate in place of y in equation we get
11 = 5 (1) +c
11= 5 + c
11-5 = c
6 = c
now, substituting the value of c in the Gradient/ slope intercept form
y = 5x + 6

Let A be the event that exactly 4 of the 8 flips are heads
⇒ n(A) = [tex]8C_4[/tex] [∵ [tex]nC_r=\frac{n!}{r!(n-r!)}[/tex]]
⇒ [tex]\frac{8!}{4!4!}[/tex] = 70
Then, P(a) = [tex]\frac{n(a)}{n(s)}[/tex]
⇒ [tex]\frac{70}{256}[/tex]
Let B be the event that the last two flips are tails
⇒ n(B) = [tex]8C_2[/tex]

Final answer:
The standard deviation from the method A is 2.87
The standard deviation from the method B is 1.35
The standard deviation from the method C is 0.42
The standard deviation from the method D is 0.75
What purposes does standard deviation serve?The standard deviation reveals the degree of data skewedness. It gauges how far away from the mean each observed value is. Approximately 95% of values in any distribution will be within two standard deviations of the mean.
The statistical concept of standard deviation is used to quantify the variability or dispersion around an average. It is a measure of volatility technically. The discrepancy between the actual and average value is known as the dispersion. The standard deviation increases as the variability or dispersion increases.
A low standard deviation indicates that the data are tightly grouped around the mean, while a high standard deviation indicates that the data are widely dispersed (less dependable) (more reliable)
Explanation:
The highest standard deviation is found in procedure A. Given that it is not based on any actual measurements and is subject to wildly different subjective judgment, one would anticipate that it would be the largest.

the top and bottom ends of a windshield wiper blade are 30 inches and 13 inches, respectively, from the pivot point. while in operation, the wiper sweeps through 135°.
The area swept by the wiper is 860.75 square inches, as calculated by the formula of area of a sector.
What is a sector and its area?A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends. A slice of pizza or a pie can be used as an analogy for the form of a circle's sector.Area of a sector = [tex]\frac{1}{2}r^{2}\theta[/tex] (where the angle is in radians)Given:
Top end of windshield = 30 inchesBottom end of windshield = 13 inchesAngle made = 135 degrees = 3π/4 radiansTo find: Area swept by the wiper.
Finding:
As area of the sector = [tex]\frac{1}{2}r^{2}\theta[/tex],
Area swept by the wiper will be given by: (Area of the sector made by the top end of the windshield) - (Area of the sector made by the bottom end of the windshield)
=> Area swept by the wiper = [tex]\frac{1}{2}(30)^{2}\frac{3\pi}{4} - \frac{1}{2}(13)^{2}\frac{3\pi}{4}[/tex]
=> Area = [tex]\frac{1}{2}\frac{3\pi}{4}(900 - 169)[/tex]
=> Area = [tex]\frac{1}{2}\frac{3\pi}{4}(731)[/tex] ≈ 860.75 square inches
Hence, the area swept by the wiper is 860.75 square inches, as calculated by the formula of area of a sector.

which conversion factors are used to multiply to 18 cm/s to get meters per minute? select each correct answer.
The conversion factor to convert cm/s to m/min is 3 / 5, it is gained by applying the knowledge of conversion of units to the given problem.
What do you mean by conversion of units?
Conversion of units deals with the method of converting a set of values given in a unit to another unit without changing its numerical value. Conversion can take place in both ways, from lower to higher units and vice-versa.
Calculation of the conversion factor to convert cm/s to m/min
We know that,
1 m = 100 cm
1 min = 60 s
To convert cm/s to m/min, we have
= 18 / (100 / 60)
= (18 × 3) / 5
= 54 / 5
= 10.8 m/min
Hence, the conversion factor used to convert cm/s to m/min is 3 / 5.
