Let us first define what any of these terms mean.

The mean is found by adding all the numbers in the set, and dividing the sum by how many numbers are found in the set.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, the sum of the numbers is 5 + 12 + 6 + 3 + 8 + 16 + 8 + 6 = 64. 64 ÷ 2 = 32. Thus, the mean is 32.

The median is found by finding the number in the middle of the set, and dividing it by 2. This is easy in odd numbers as there is only one number in the middle that is the same amount of numbers left and right proportionally. However, in even numbers, there are two middles to be proportional. If it as an even number, then add the 2 middles together, and divide by 2.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, this set has an even number of numbers in the set. Thus, the middles are 3 and 8. 3 + 8 = 11, and 11 ÷ 2 = 5.5. Thus, the median is 5.5.

The mode is the number that most frequently appears in the set. In this case, we have 2 frequent numbers. That is 6 and 8. They both appear 2 times separately. Thus, 6 and 8 are the modes of this set.

The range is the difference (i.e subtraction) between the largest number on the set and the smallest number on the set.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, the range is 16-3 or 13. Thus, the range is 13.

Now that we have the definitions, we can compute the other set very easily.

> Given set {2, 7, 4, 11, 12, 4, 6}, the mean is 18.

> Given set {2, 7, 4, 11, 12, 4, 6}, the median is 5.5.

> Given set {2, 7, 4, 11, 12, 4, 6}, the mode is 4.

> Given set {2, 7, 4, 11, 12, 4, 6}, the range is 10.

Bobby is a freshman in high school and he just received $500 for graduation from middle school from his grandparents. he wants to save his $500 for college in 4 years if he deposits his $500 into a simple interest savings account for the next 4 years that has a rate of 2.85%. how much will he have in his account after 4 years?

Answers

Bobby will have $557 in his account after 4 years.

What is simple interest?

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account.

Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

Simple interest = (principal amount×Rate of interest×time-period)/100

The principal amount deposited was $500.

The rate of interest given by the bank is 2.85%.

The duration of deposit is 4 years.

Simple interest = (500×2.85×4)/100

                         = 57

Simple interest given by the bank after 4 years is $57.

The total sum of money Bobby will have in his bank is $500 + $57 = $557.

Therefore, after 4 years Bobby will have $557 in his account.

Step-by-step explanation:

We can't evaluate f(2)  because we don't have f(x), if we did, we would plug in 2 for x.

On the other hand, solve f(x) = 2 asks for what x is equal to when f(x) = 2, f(x) is just the value on the y axis in relationship with x (in short terms, the value on the y axis).

Answer:

Step-by-step explanation:

a = 12 mi

b 14.0 mi

c = 7 mi

m∠A59.0 °

m∠B ≈ 91°

m∠C30.0 °

The lengths of the triangle are:

a = 12 mi

b ≈ 14.0 mi

c = 7 mi

And the angles of the triangle are :

m∠A ≈ 59.0°

m∠B ≈ 91°

m∠C ≈ 30.0°

What are the angles in a triangle?

Every triangle has interior angles that total 180.

Angles in a triangle are the total (sum) of the angles at each of its three vertices.

Given, in a triangle ∠B is = 91°

length of c = 7 mi

              a = 12 mi

We need to find the missing angles and side length of b.

⇒ b² = a² ₊ c² ₋ 2accosB

⇒ b/sinB = a/sinA = c/sinC

b² = 12² ₊ 7² ₋ 2(12)(7)cos91°

b² = 144 ₊ 49 ₋ 2(84)cos91°

b² = 193 ₋ 168 cos 91°

b² = 195.856

b=√195.856

b = 14.0 mi

⇒14.0/sin91° = 12/sinA

⇒ sinA = 12sin91°/14.0

sin A = 0.857

A = arcsin(0.857)

A = 59.0°

∴ C = 180° ₋ (sum of two angles in a triangle)

C = 180 ₋ (91° ₊ 59°)

C = 180 ₋ 150°

C = 30°

Hence we get the angles in the triangle as m∠A = 59.0°, m∠B = 91° and  m∠C = 30°

What is the shaded portion of the figure?

Answers

Answer:

D

Step-by-step explanation:

Area of Part of a Circle = (θ/360)[tex]\pi r^{2}[/tex]

We first find the area of CAB first.

Radius of CAB = AB = 6cm

θ  = 112

Area of CAB = [tex]\frac{112}{360} \pi (6)^{2} \\=\frac{56}{5} \pi cm^{2}[/tex]

Next we will find the area of FAE.

Radius of FAE = AE = 4cm

Area of FAE = [tex]\frac{112}{360} \pi (4)^{2} \\=\frac{224}{45} \pi cm^{2}[/tex]

Lastly,

Area of Shaded Region = Area of CAB - Area of FAE

= [tex]\frac{56}{5} \pi -\frac{224}{45}\pi \\=\frac{56}{9} \pi cm^{2}[/tex]

Therefore the answer is D.

The first three values of g² + 3 are 3, 4, 7. The correct option is the first option 3, 4, 7

Evaluating an expression

From the question, we are to determine the first three possible values of g² + 3

From the given information,

g stands for a whole number

∴ The first three values of g are 0, 1, 2

When g = 0

g² + 3 becomes

0² + 3

= 0 + 3

= 3

When g = 1

g² + 3 becomes

1² + 3

= 1 + 3

= 4

When g = 2

g² + 3 becomes

2² + 3

= 4 + 3

= 7

Hence, the first three values of g² + 3 are 3, 4, 7. The correct option is the first option 3, 4, 7.

Usually, factorization or factoring means writing a number (or another mathematical object) as a product of minor or more uncomplicated objects of the same kind.

Given -x-5 is a linear expression.

For factorizing, first, make the coefficient of x positive. For this take -1 common.

⇒ -x-5 = [tex]-1\times(x+5)[/tex]

Now take the greatest common divisor (gcd) of absolute values of coefficients in x+5.

The distance along the curved surface, measured from the edge at the top to a point on the circumference of the circle at the base, is known as the slant height of an object (such as a cone or pyramid).

A fast food restaurant executive wishes to know how many fast food meals adults eat each week. They want to construct a 90% confidence interval for the mean and are assuming that the population standard deviation for the number of fast food meals consumed each week is 1.4. The study found that for a sample of 1271 adults the mean number of fast food meals consumed per week is 3. Construct the desired confidence interval. Round your answers to one decimal place.

Answers

The confidence interval which shows 90% confidence level for the mean and assumed standard deviation is (2.94 meals, 3.0565 meals).

Given standard deviation=1.4. Sample size =1271, mean=3.

We have to find the confidence interval for 90% confidence level.

We have to find out α level that is the subtraction of 1 by the confidence interval divided by 2.

α=(1-0.90)/2

=0.05

Now we have to find z in the z table as such z has a p value of 1-α so it is z with p value of 1-0.05=0.95

Z=1.44 from z table.

Now find M as such that

M=z* st/[tex]\sqrt{n}[/tex]

where st is standard deviation ,n is sample size.

M=1.44*1.4/[tex]\sqrt{1271}[/tex]

=1.44*1.4/35.65

=2.016/35.65

=0.0565

Lower end= mean -M

=3-0.0565
