Using complementary angles, the measure of angle 4 is of 39º.
What are complementary angles?If two angles A and B are complementary, the sum of their measures is of 90º.
In this problem, angles 3 and 4 are complementary, hence:
m<3 + m<4 = 90º.
Angles 1 and 3 are opposite by the same vertex, hence they are congruent and we can find x as follows:
m<1 = m<3
4x - 13 = 2x + 19.
2x = 32
x = 16.
The measure of angle 3 is given by:
m<3 = 2(16) + 19 = 51.
Hence the measure of angle 4 is found as follows:
m<3 + m<4 = 90º.
51 + m<4 = 90º.
m<4 = 39º.

differences between two samples are more likely to be statistically significant if the samples are and the standard deviations of the samples are .
Answers
The differences between two samples are more likely to be statistically significant if the samples are and the standard deviations of the samples are: large and the standard deviations of the samples are small.
What is statistical significance?Statistical significance can be used to determine whether a result is more likely the consequence of chance or an important element.Significant results simply imply that you can be sure they are true rather than that you were fortunate (or unfortunate) in the sample you used.Now,
It can be presumed that the test mentioned is the t-test since it uses two samples. A t-t-value, test's which it generates, is what determines its statistical significance. The likelihood that a difference is statistically significant increases with increasing t-value. By dividing the mean difference between two samples by the square root of the sum of the variances of each sample, then by the size of each sample, one may determine the t-value.The likelihood that the difference between two means is statistically significant therefore increases if:a significant mean difference;the samples are substantial;The samples' standard deviations are lower.Hence, The differences between two samples are more likely to be statistically significant if the samples are and the standard deviations of the samples are: large and the standard deviations of the samples are small.

Based on the congruence statement triangle △SUN ≈ △FOG, the true statement is SU is Congruent to side FO.
Congruence of the triangle:
Two triangles are said to be congruent if one can be placed over the other so that they coincide (fit together). This means that congruent triangles are exact copies of each other and when fitted together the sides and angles which coincide, called corresponding sides and angles, are equal.
For example,
△ABC ≈ △DEF

Answers
An inequality that represents the number of hot dogs per minute joey could eat for the last 9 minutes to break his record is: 9d + [tex]11\frac{1}{4}[/tex] > 72
For given question,
Joey chestnut is trying to break his own record for eating the most whole hot dogs in 10 minutes.
He needs to eat more than 72 hot dogs to break his record.
After 1 minute, joey has eaten [tex]11\frac{1}{4}[/tex] hot dogs.
let d represent the number of hot dogs joey eats per minute for the next 9 minutes.
9d + [tex]11\frac{1}{4}[/tex] is the expression that shows how many hot dogs he will eat in total.
9d being how much he'll eat in the remaining 9 minutes, and [tex]11\frac{1}{4}[/tex] being the number of hot dogs he's already eaten in the first minute.
Since it has to beat his former record of 72, it has to be greater than 72. The inequality would be
9d + [tex]11\frac{1}{4}[/tex] > 72
Therefore, an inequality that represents the number of hot dogs per minute joey could eat for the last 9 minutes to break his record is:
9d + [tex]11\frac{1}{4}[/tex] > 72

Using the multiplication and the subtraction property, we can prove that the value of y in the equation given is: 7. (see proof below).
How to Solve an Equation?Given the equation, y + 2/3 = 3, to prove that y = 7, we have to solve the given equation in other to find the value of y which must be equal to 7.
(y + 2)/3 = 3 [given]

To enter an arcade, Linus has to pay a $5 fee. In addition, every arcade game costs an additional $0.25 to play one round. The relationship between the amount of Linus' money spent, or C, and the number of rounds of arcade games played, or r, can be modeled by the equation C=0.25r+5.
Answers
The amount of Linus's money spent on 200 rounds of arcade game is $55.
The given question is incomplete, so
Lets suppose that Linus has played 200 round of arcade game and now we will need to determine the amount of Linus's money spent on 200 rounds of arcade game.
Entrance fee of an arcade = $5
Additional cost to play one round = $0.25
With the help of given equation ( C=0.25r+5 ) we will determine the amount of Linus's money spent on 200 rounds of arcade game.
'C' = The relationship between the amount of Linus' money spent
'r' = The number of rounds of arcade games played
Let's solve the equation now,
As we know that r is number of rounds Linus has played which is 200 rounds.
So, C = 0.25r+5
C = 0.25 × 200 + 5
C = 50 + 5
C = $55
Hence, we got that Linus has spent total $55 on 200 rounds of arcade game.

PLEASE HELP!!!
Answers
The solutions to the absolute value equation given by the word phrase; Absolute value of the quantity one third times x plus 9 end quantity minus 3 equals 21 are; x = −99 and x = 45.
What are the solutions of the absolute value equation as given in the task content?It follows from the task content that the solutions to the absolute value equations as given by the word phrase are to be determined.
Given;
| (1/3)x + 9 | - 3 = 21
Add 3 to both sides;
| (1/3)x + 9 | = 24
Hence, the result equations are; (1/3)x + 9 = 24 OR (1/3)x + 9 = -24.
Therefore, we have;
(1/3)x + 9 = 24
(1/3)x = 24 - 9
(1/3)x = 15
x = 45.
Also, considering the other equation;
(1/3)x + 9 = -24
Subtract 3 from both sides;
(1/3)x = -33
Multiply both sides by 3;
x = -99.
Ultimately, the solutions of the equation are;
x = −99 and x = 45.
Therefore, the solutions to the absolute value equation given by the word phrase; Absolute value of the quantity one third times x plus 9 end quantity minus 3 equals 21 are; x = −99 and x = 45.

you are leaving for a concert that starts in 5 hours and is 305 miles from your house. what average speed (in miles per hour) would allow you to arrive at the concert on time? miles per hour school starts in 37 minutes and you live 17 miles from school. what average speed (in miles per hour) would allow you to arrive at school on time? miles per hour
Answers
The average speed required to reach the concert in time is 61 miles per hour.
The average speed required to reach school in time is 27.567 miles per hour.
What is the average speed?
The average speed of an object is defined as the total distance travelled by an object in a particular interval of time or average time. Mathematically, average speed = total distance / total time taken. Its SI unit is m/s.
Calculation of the average speed
We are given that a concert starts in 5 hours and is 305 miles away from the house, i.e. time = 5 hours and distance 305 miles
Then the average speed in miles per hour is given by total distance / total time
Average speed = 305 / 5
= 61 miles per hour
Further, the time taken to reach school is 37 minutes which when converted to hours becomes 37 / 60 hour
The distance between school and home is 17 miles
So, the average speed = total distance / total time
= 17 / (37 / 60)
= (17 × 60) / 37
= 27.567 miles per hour
Hence, the average speed required to reach the concert in time is 61 miles per hour.
The average speed required to reach school in time is 27.567 miles per hour.
