30                   1             40

Step-by-step explanation:

Find out how many times an element(data value) appears. That will be the frequency(column 2). The cumulative frequency is the total of all frequencies prior to that element plus the current element frequency

Cumulative frequency for first element is same as its frequency

Cumulative frequency for element 16 is 3 + 6 = 9

Cumulative frequency for element 17 = 3 + 6 + 1 = 9 + 1=10. Basically it is the sum of the previous element cumulative frequency + the current frequency

5,435,778 in scientific notation will be 5.435778×10⁶.

The slope of the line shown is -2/3

The formula for calculating the slope of a line is expressed according to the formula

Slope = Rise/Run

Slope = y₂-y₁/x₂-x₁

Using the coordinate point (-9,-2) and (-6, -4)

Slope = -4+2/-6+9
Slope = -2/3

Slope = negative two third

(3a) The 95% confidence interval of σ[tex]_{1}^{2}[/tex]/σ[tex]_{2}^{2}[/tex] is: [0.1932 , 1.2032].

Variance is the anticipated squared deviation of a random variable from its population mean or sample mean in probability theory and statistics.

F test for variances, using F distribution ([tex]df_{num}[/tex]=19,[tex]df_{denom}[/tex]=20) (two-tailed) (validation).

Hypotheses

[tex]H_{0}:sigma_{1} = sigma_{2}\\\\H_{1}:sigma_{1}\neq sigma_{2}[/tex]

1. H0 hypothesis

Since p-value > α, H0 is accepted.

The sample standard deviation (S) of LaJolla.res' population is considered to be equal to the sample standard deviation (S) of Pt.Loma.ke's population.

In other words, the difference between the sample standard deviation (S) of the LaJolla.res and Pt.Loma.ke populations is not big enough to be statistically significant.

2. P-value

The p-value equals 0.1152, ( p(x≤F) = 0.05759 ). It means that the chance of type I error, rejecting a correct [tex]H_{0}[/tex], is too high: 0.1152 (11.52%).

The larger the p-value the more it supports [tex]H_{0}[/tex].

3. The statistics

The test statistic F equals 0.4796, which is in the 95% region of acceptance: [0.3986 : 2.4821].

It will take 14.02 weeks for both the accounts to have the same balance

Bank account balance of Rhiannon = -$253.50

Money deposited by Rhiannon in the bank account each week = $35.80

Bank account balance of Sophie = -$78.25

Money deposited by Sophie in the bank account each week = $23.30

Let the number of weeks it takes to have the same account balance be x, therefore formulating the algebric equation we get:

Bank balance of Rhiannon + Money deposited by her each week*No of weeks it will take for the balance to be equal = Bank balance of Sophie + Money deposited by her each week*No of weeks it will take for the balance to be equal

= -253.5 + 35.8(x)  = -78.25 + 23.3(x)

= -175.25 = -12.5(x)

x =  14.02 weeks

Therefore, it will take 14.02 weeks for both the accounts to have the same balance

125 is greater than 23.

Given the question is to explain 125 > 23.

Here we have two numbers which are 125 and 23.

Inequalities:

Whenever we check the number which is greater or lesser by taking the difference between those two numbers we conclude which is greater or lesser.

If the difference between the numbers gets a positive number then the first number is greater than the second.

If the difference between the numbers gets a negative number then the first number is lesser than the second.

If the difference between the numbers gets zero value then the two numbers are equal.

So the difference between the given two numbers are

= 125 - 23

= 102

Answer:

22

Step-by-step explanation:

By the segment addition postulate, FH=8+14=22.

The equation will be,

→ FH = FG + GH

Then the value of FH will be,

→ FH = 8 + 14

→ [ FH = 22 ]

Hence, the value of FH is 22.

The average rate of change of f(x) on the interval [1,1+h] is [1/(h + 6) - 1/6]/h

The function is given as

f(x) = 1/(x + 5)

The interval is given as

[1, 1 + h]

Calculate f(1) as follows

So, we have

f(1) = 1/(1 + 5)

f(1) = 1/6

Calculate f(1 + h) as follows

So, we have

f(1 + h) = 1/(1 + h + 5)

f(1 + h) = 1/(h + 6)

The average rate of change of f(x) on the interval [1,1+h] is then calculated as

Rate = [f(1 + h) - f(1)]/[1 + h - 1]

This gives

Rate = [1/(h + 6) - 1/6]/h

Hence, the average rate of change of f(x) on the interval [1,1+h] is [1/(h + 6) - 1/6]/h

The measure of an angle 2 is 85°.

Given that, ∠6=9x+13 and ∠2=11x-3.

Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line.

As we know, corresponding angles are congruent.

So, ∠6= ∠2

⇒ 9x+13=11x-3

⇒ 13+3=11x-9x

⇒ 16=2x

⇒ x=8

Now, ∠2=11x-3

=11×8-3=85°

Answer:

3.14159

Step-by-step explanation:

The value of π correct to 5 decimal places is 3.14159.

Decimal numbers are numbers which includes a whole number part and a fractional part.

The point separating both parts is the decimal point.

Pi, which is written as the Greek symbol π, is defined as the ratio of the circumference of any circle to the diameter of that circle.

We know that,

Circumference of a circle, C = 2 π r, where r is the radius.

2r will be the diameter.

π = C / 2r

The value of pi to 5 decimal places = 3.14159

Normally we use 3.14.

Hence the value of pi is 3.14159 to 5 decimal places.

The number of days taken to complete the production of a batch of pens are 22, as calculated by basic algebra.

Numbers, variables, constants, expressions, equations, linear equations, and quadratic equations are all part of the basics of algebra. Additionally, the algebraic expressions contain the basic arithmetic operations of addition, subtraction, multiplication, and division.

Now, According to the question, the factories used all 12 machines in the last days, Also, for the first 8 days, only 9 machines were in use.

Thus, If the factories used all 12 machines, the batch of pens took 20 days to be manufactured.

Hence, the equation formed from the given information by basic algebra is: 20 + 12 - 9(8) / 12

28 - (72/12)

=28 - 6 = 22

Hence, The number of days taken to complete the production of a batch of pens are 22, as calculated by basic algebra.

Bisects means that ∠RED will be divided in two parts by segment EB. This means that ∠REB = ∠BED. So,

5x-3 + 5x-3 = 8x+16

10x-6 = 8x+16

2x = 22

Therefore, ∠BED = 52°

No, it is not it true that for any integer n ≤ 2, φ(n) has a primitive root

In modular arithmetic, a number g is called a primitive root modulo n if every number  coprime to n is congruent to a power of  modulo . Mathematically, g is a primitive root modulo n if and only if for any integer  a such that gcd(a, n)=1 , there exists an integer k such that:
