Here is a growing pattern of sequences:
Answer:
A, C, F
Step-by-step explanation:
The first figure is drawn using 8 squares. The next uses 11 squares, and the one shown in Step 3 uses 14 squares. The numbers of blocks follow the sequence ...
8, 11, 14
which begins with 8 and increases by 3 from one step to the next. This constant increase from one term to the next makes it an arithmetic sequence.
__
explicit formThe general term, an, of an arithmetic sequence can be written in terms of its first term, a1, and its common difference, d, as ...
an = a1 +d(n -1)
When the first term is a1=8, and the common difference is d=3, this becomes ...
an = 8 +3(n -1)
which simplifies to
an = 8 +3n -3 = 3n +5
Written in functional form, these explicit equations are ...
f(n) = 8 +3(n -1) . . . . . matches choice A
f(n) = 3n +5 . . . . . . . . matches choice F
__
recursive formThe recursive form of the definition of a sequence starts with the first term, then tells you how to obtain the next term from that. Here, the first term is ...
f(1) = a1 = 8
and each term is 3 more than the last:
f(n) = 3 +f(n-1) . . . . . . . . . 3 is added to the previous term
Together, this is ...
f(n) = 8, f(n) = 3 +f(n -1) . . . . . matches choice C

Answer:
Part A:
In order to find a coterminal angle, or angles of the given angle, simply add or subtract 360 degrees of the terminal angle as many times as possible.
Part B:Simply put, coterminal angles start at 0° and end at the same place, though in different directions and multiple times around (you're probably going to want to make that sound a little more formal). Since each time around is 360°, boom
Part C: 75° is in Quadrant II, right? If I go one more time around, 75 + 360 = 435°. I can also go "backward. Starting at 0 and going clockwise, I'm going 75 fewer degrees than all the way around, so 360-75 = 285° but since I'm going "backward" 75 - 360 = -285°. One more is on you.

Step-by-step explanation:
Important angle relationships that will help us answer this question :
Supplementary angles : Supplemtary angles are angles that for a straight line. The sum of these angles is 180 degrees.Corresponding angles : corresponding angles are angles that are on the same side of the traversal as well as the same side of the intersecting lines. These angles are congruent ( equal to each other ) if the two lines that they fall on are parallel ( which they are )Opposite exterior angles - These angles are angles on the very outside of the lines and are on opposite sides of the transversal. These angles are congruent as wellFor more clarification kindly view the attached images :)
Using these angles relationships, we can easily find the answer two different ways.
First way :
Creating an equation : We want to find the measure of angle MPN. It's important to note that this angle falls on a line made up of other angles ( angle mpe and angle npe ) forming a straight line ( line e )
Using our angle relationships we know that angles that form a straight line are supplementary and add up to 180 degrees.
So we can say angle mpe + angle npe + angle MPN = 180. ( we can use this equation to solve for angle MPN )
Here we are given that angle mpe is a right angle ( indicated by the little square ) meaning it has a measure of 90 degrees.
So we can further simplify our equation saying that angle npe + 90 + angle MPN = 180 ( by plugging in angle mpe = 90 )
Now if you didn't know we can solve an equation ( find the missing angle ) if there is a single variable ( in this case we want the variable to be angle MPN ). This means that in order to solve for angle MPN we just find the measure of the other angle, angle npe.
Finding angle npe
The angle under "x" is corresponding to angle mpE so we can say the angle under x = angle npe.
The angle under x also appears to be supplementary to the angle with a measure of 153 degrees. So we can say that angle under x + 154 = 180
Subtracting both sides by 153 we get that angle under x = 180 - 154 = 26 degrees.
Because the angle under x and angle npe are corresponding and equal to each other, angle npe also has a measure of 26 degrees.
Finishing creating the equation and solving for angle MPN : So we have angle npe + angle mpe + angle MPN = 180
We know angle mpe = 90 and angle npe = 26
So we can say 90 + 26 + angle MPN = 180
Now we can solve for angle MPN
90 + 26 + angle MPN = 180
==> combine like terms
116 + angle MPN = 180
==> subtract 116 from both sides
angle MPN = 64 degrees
Second way :
We can also solve for angle MPN using the angle relationship " opposite interior angles "
The angle with a measure of 154 degrees and angle ePN are opposite exterior angles meaning they are congruent. ( so angle ePN = 154 )
Angle ePN is made up of angle mpe and angle MPN. This means that angle mpe + angle MPN = 154
We've already identified that angle mpe = 90 degrees because it's a right angle so we can say angle angle MPN + 90 = 154
Subtracting both sides by 90 we get that angle MPN = 154 - 90 = 64 degrees
And we are done!

The average age of a father and his four children is 12 years. The children are aged 3, 5, 6 and 10 years. Find the age of the father.
Answer:
Father=36 years old
Step-by-step explanation:
5 people 4 children and a father
average age=12
add the ages
3+5+6+10=24
24+12=36
check the work
36 +24=60
60/5=12
answer=36
Answer:
36 years old
Step-by-step explanation:
The average age of father and four children can be expressed in mathematics as:
[tex]\displaystyle \large{\dfrac{f+c_1+c_2+c_3+c_4}{5}}[/tex]
The above expression is what you call average value or mostly known as mean - the mean value is sum of all data values divided by number of data values. The formula reference for mean/average value is:
[tex]\displaystyle \large{\dfrac{x_1+x_2+x_3+...+x_n}{n} = \dfrac{1}{n} \sum_{i=1}^n x_i}[/tex]
Determine or let the following be:
f = father’s agec1 = first child’s agec2 = second child’s agec3 = third child’s agec4 = fourth child’s ageIt is also given in the question that children’s ages are 3, 5, 6 and 10. Hence:
[tex]\displaystyle \large{\dfrac{f+3+5+6+10}{5} = 12}[/tex]
From above, it is also given that average of father’s age and children’s age is 12 years old - that now gives us an equation. What we have to do now is to solve for f.
First, multiply 5 both sides to get rid of denominator.
[tex]\displaystyle \large{\dfrac{f+3+5+6+10}{5} \cdot 5 = 12 \cdot 5}\\\\\displaystyle \large{f+3+5+6+10=60}[/tex]
Evaluate 3+5+6+10 which equals 24.
[tex]\displaystyle \large{f+24=60}[/tex]
Next, subtract both sides by 24 to isolate f-term.
[tex]\displaystyle \large{f+24-24=60-24}\\\\\displaystyle \large{f=36}[/tex]
Finally, we have received the value of term which is f = 36. We know that the term represents father’s age and therefore, father’s age is 36 years old!

A water tank is built in the form of a right rectangular prism, with dimensions that measure 17.6 ft by 12.6 ft by 10.4 ft. How many cubic feet of water would it hold when it’s a quarter full?
Volume is a three-dimensional scalar quantity. The amount of water that this tank will hold till it is a quarter full is 576.576 ft³.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The total volume of the right rectangular prism will be,
Total Volume = 17.6ft × 12.6ft × 10.4ft
= 2306.304 ft³
Since the total volume of the right rectangular prism is 2306.304 ft³, the water it will hold will be equal to its volume.
Now, the amount of water that this tank will hold till it is a quarter full is,
Amount of water = Total volume /4
= 2306.304ft³ / 4
= 576.576ft³
Hence, the amount of water that this tank will hold till it is a quarter full is 576.576 ft³.

Using the information in the diagram, what is the height of the tree to the nearest foot?
45 ft
54 ft
60 ft
135 ft
The relationship between the corresponding sides of similar triangles indicates that the height of the tree is 60 feet. The correct option is therefore;
60 ftWhat are similar triangles?Similar triangles are triangles in which the ratio of the corresponding sides of the triangles are equivalent for the three sides of the triangle.
The location of the tree divides the hypotenuse side and the base of the triangle formed by the building into two parts of the same length, therefore;
The length of the hypotenuse side to the building = 2 × 108 ft = 216 ft
The length of the base to the building = 2 × 90 ft = 180 ft
The ratio of corresponding sides of similar triangles and the trigonometric ratio of sines, indicates that we get;
Height of the tree/108 = 120/216
Height of the tree = 108 × (120/216) = 60 feet

A study of the amount of time it takes a specialist to repair a mobile MRI shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 32 broken mobile MRIs are randomly selected, find the probability that their mean repair time is less than 8.9 hours.
Using the normal distribution, it is found that there is a 0.0582 = 5.82% probability that their mean repair time is less than 8.9 hours.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem, the parameters are given as follows:
[tex]\mu = 8.4, \sigma = 1.8, n = 32, s = \frac{1.8}{\sqrt{32}} = 0.3182[/tex]
The probability that their mean repair time is less than 8.9 hours is the p-value of Z when X = 8.9, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{8.9 - 8.4}{0.3182}[/tex]
Z = 1.57
Z = 1.57 has a p-value of 0.9418.
1 - 0.9418 = 0.0582.

Answer:
range is 515, mode:All values are equal, Median is 243 and the mean is 311.18
mean:to find the mean you need to add up all you numbers so all of these add up to be 3423 and then you divide by the amount of numbers which it 11 so 11 / 3423 = 311.18 so the answer is the mean is 311.18
median: to find it you need to put all the numbers smallest to biggest so it would be in the order 155, 175, 190, 210, 213, 243, 340, 380, 390, 457, 670 and then you pick the one in the middle and that would be 243
mode:All values appeared just once so there is not one
range: to find the range to need to find the differences in the smallest to the biggest number so smallest one is (155) biggers (670) so 155 - 670 = 515 so the range is 515
