Root 40 to the nearest 10 is 6.3
The root of a number in math is a number that when multiplied by itself produces the original number. For example, the square root of 49 is 7 because 7×7=49.
Rounding off to the nearest 10 means that we wish to round off the last two digits of a number, that is up to the tens place of a number.
We have been given that 40 is the number whose root we have to round off so here are step-by-step instructions for how to get the square root of 40 to the nearest tenth:
Step 1: Calculate. We calculate the square root of 40 to be: √40 = 6.32455532033676.
Step 2: Reduce. 6.32.
Step 3: Round. Round 6.32 so you only have one digit after the decimal point to get the answer: 6.3.
So therefore the nearest 10 of root 40 is 6.3

You invest $2,800 at a 6 nnual interest rate, stated as an apr. interest is compounded monthly. how much will you have in 1 year? in 1.5 years?
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
The Future value in 1 year= 2800x[tex](1+0.06/12)^{1x12}[/tex]
= $2972.70
The Future value in 1.5 years=2800x[tex](1+0.06/12)^{1.5x12}[/tex]
= $3063.00

What do you mean by the term hexadecimal?The hexadecimal numeral system, usually known as base 16 or just "hex," is a positional numeral system used in mathematics and computing that uses the radix (base) of 16 to represent integers. Hexadecimal uses 16 different symbols as opposed to the decimal system's 10 symbols, with the most common being "0"-"9 to represent values 0 to 9 and "A"-"F" (or alternatively "a"-"f") to represent values 10 to 15. Hexadecimal numbers are frequently used by software engineers and system designers because they offer a human-friendly representation of binary-coded data. For example, an 8-bit byte might have values ranging from 00000000 to 11111111 in binary form, which can be succinctly represented as 00 to FF in hexadecimal. Each hexadecimal digit represents four bits (binary digits), often known as a nibble (or nybble).

Step-by-step explanation:
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

patricia will flip the coin 8 times. let a be the event that exactly 4 of the 8 flips are heads, and b be the event that the last two flips are tails. find p(a ∪ b).
The probability of an event of P(A∪B) is 49/128.
In this question,
Patricia will flip the coin 8 times.
The sample space is the flipping of a coin 8 times.
⇒ n(s) = 2⁸
⇒ n(s) = 256
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]
⇒ [tex]\frac{8!}{2!6!}[/tex] = 28
Then, P(a) = [tex]\frac{n(b)}{n(s)}[/tex]
⇒ [tex]\frac{28}{256}[/tex]
Now, P(A∪B) = P(A) + P(B)
⇒ P(A∪B) = [tex]\frac{70}{256} + \frac{28}{256}[/tex]
⇒ P(A∪B) = [tex]\frac{70+28}{256}[/tex]
⇒ P(A∪B) = [tex]\frac{98}{256}[/tex]
⇒ P(A∪B) = [tex]\frac{49}{128}[/tex]
Hence we can conclude that the probability of an event of P(A∪B) is 49/128.

Step-by-step explanation:
The symbol ^ means raised to a power.
Formula for Volume of Sphere - V = 4/3 π r^3
1. To find the volume of a sphere, first find the radius with the given diameter 16.
16 ÷ 2 = 8
Radius = 8
2. Substitute r for 8 and solve, and 3 will be used for π.
V ≈ 4/3 • 3 • 8^3
V ≈ 4/3 • 3 • 512
V ≈ 4/3 • 1536
V ≈ 6144/3

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 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
