Answer:
163/30
Step-by-step explanation:
4 3/5 in mixed number form would be 23/5
5/6 remains 5/6 as it is not greater than 1, therefore it cannot be simplified.
23/5 + 5/6
in order to add, we have to make the denominators alike. the least common multiple is 30. so we have to not just multiply the denominators by whatever results in 30, but also the numerators.
23 times 6 = 138
5 times 6 = 30
5 times 5 = 25
5 times 6 = 30
138/30 + 25/30
at this point, we can simply just add the numerators
163/30

a t test yields the probability (p value) that the null hypothesis is: select one: a. correct. b. incorrect. c. a direct correlation. d. an inverse correlation.
The t-test yields the probability (p value) that the null hypothesis is option (B) incorrect
The p-value in a t-test represents the probability of obtaining the observed test statistic (or one more extreme) assuming that the null hypothesis is true. The null hypothesis is typically a statement of "no effect" or "no difference" between two groups being compared in the test.
Therefore, a low p-value (generally less than 0.05) indicates that the observed data is unlikely to have occurred by chance under the null hypothesis and suggests that the null hypothesis is likely to be false.
In other words, a low p-value provides evidence against the null hypothesis and in favor of the alternative hypothesis (which typically represents the hypothesis that the researchers are interested in testing).
Thus, the p-value does not directly tell us whether the null hypothesis is correct or incorrect, but rather whether the evidence supports rejecting it or not.
Therefore, the correct option is (B) incorrect

which of these statements about a normally distributed data set is true? a.) the smaller the standard deviation, the less concentrated the data will be. b.) the concentration of the data set is not related to the standard deviation. c.) the smaller the standard deviation, the more concentrated the data will be. d.) the greater the standard deviation, the more concentrated the data will be.
The Statement which is true is (c) the smaller the standard deviation, the more concentrated the data will be.
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
A standard deviation close to zero indicates that data points are close to the mean, whereas a high or low standard deviation indicates data points are respectively above or below the mean.
The smallest possible value for the standard deviation is 0, and that happens only in contrived situations where every single number in the data set is exactly the same

Longitude and latitude can be easily calculated by observing the direction that the fish are swimming.
True
False
Answer:
False.
Step-by-step explanation:
Longitude and latitude are geographical coordinates used to determine the location of a place on the earth's surface. They are not easily calculated by observing the direction that fish are swimming. Latitude is determined by observing the position of the sun relative to the earth's equator and longitude is determined by observing the position of the sun relative to the Prime Meridian. To accurately calculate latitude and longitude, one would need to use specialized instruments, such as a sextant, or rely on GPS technology. Observing the direction that fish are swimming would not provide enough information to accurately determine latitude and longitude.
False
the longitude and latitude can be easily calculated and determined with using a map not by observing the direction that the fish are swimming.
Explain how to calculate 5% of 260 by first calculating 1% of 260
The value of 5% of 260 is 13 as it is 5 times of 1% of 260 and the value of 1% of 260 is 2.6.
Percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
so, according to the question
Let 1% of 2600 = X
1/100 * 260 = X
X = 2.6
5% is 5 times of 1% so we can just multiply the value we got after 1% of 260
i.e., 2.6
so 5% of 260 is 5 * 2.6
= 13.0

A baker initially makes 10 loaves of bread and sells 2 loaves each day.
What equation models the situation, where x is time in days and y is number of loaves?
Y=2x+10
Y=2x-10
Y=-2x+10
Y=-2x-10
Answer:
y = 2x + 10
Step-by-step explanation:
y = 2x + 10
y is the total number of loaves of bread.
x is the number of days.
If the baker baked for ten days, he would have 30 loaves of bread
y = 2x + 10
y = 2(10) + 10
y = 20 + 10
y = 30
If he baked for 50 days, he would have baked 110 loaves
y = 2x + 10
y = 2(50) + 10
y = 100 + 10
y = 110

The number of two-point field goals that lidnsey made was 71 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 21 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals lindsey made during the 2006 regular season.
Lindsey made 35 free throws, 143 two-point field goals, and 107 three-point field goals during the 2006 regular season.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let's denote the number of two-point field goals Lindsey made by x, and the number of three-point field goals she made by y.
x + y + (x+y-71)/2 + (x+y-71)/2 - 21 = 862 (total points equation)
x = 2y - 71 (two-point field goals equation)
Simplifying the first equation and substituting the second equation, we get:
3x + 3y = 1964
Substituting x = 2y - 71 into this equation, we get:
3(2y-71) + 3y = 1964
Solving for y, we get:
y = 107
Substituting this value into the equation x = 2y - 71, we get:
x = 143
Now, (x + y - 71)/2 - 21 = (143 + 107 - 71)/2 - 21 = 35

The most reasonable answer for left pocket money to Jesse after spending it on Monday, Tuesday and Wednesday is 1/8.
Let's assume that the amount of pocket money Jesse has is "x".
On Monday, he spends 1/2 of his pocket money, so he has 1/2 of his pocket money left:
Amount left after Monday = x - (1/2)x = (1/2)x
On Tuesday, he spends 2/3 of what is left, which is 2/3 of (1/2)x:
Amount left after Tuesday = (1/2)x - (2/3)(1/2)x = (1/6)x
On Wednesday, he spends 1/4 of what remains, which is 1/4 of (1/6)x:
Amount left after Wednesday = (1/6)x - (1/4)(1/6)x = (1/8)x
Therefore, the fraction of the pocket money he has left is:
Amount left / Original amount = (1/8)x / x = 1/8
So, the most reasonable answer is 1/8.

Lin is shopping for a couch with her dad and hears him ask the salesperson, "How much is your commission?" The salesperson says that her commission is 6% of the selling price. How much commission will the salesperson earn by selling a couch for $495?
The commission amount the salesperson earn is $29.7.
What is a percentage?The percentage formula is dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Selling price = $495
Commission = 6%
Now,

The pivot point (P) of the main supporting arm (AP) of a construction crane is 46 metres above the top of a 96 metre tall office building. When the supporting arm is at an angle of 55° to the horizontal, the length of cable dropping from the point A to the ground is 215 metres. Find the length of the main supporting arm (AP), to the nearest centimetre.
Answer: Let's call the length of the main supporting arm AP = x.
We can use the Pythagorean theorem to find the length of the cable dropping from point A to the ground:
c^2 = x^2 + (46 - 96 + 215)^2
c^2 = x^2 + (175 - 50)^2
c^2 = x^2 + 125^2
c^2 = x^2 + 15625
Since the angle between the main supporting arm and the horizontal is 55°, we can use the trigonometric relationship between the length of the opposite side (the cable) and the length of the adjacent side (the main supporting arm) to find x:
tan 55° = c / x
x / c = tan 55°
x / 215 = tan 55°
x = 215 * tan 55°
The value of x can be calculated using a scientific calculator or by using a table of tangent values. To the nearest centimetre, x = 204 cm.

Areflection over the line y-3
Areflection over the line x-3

A statement which best describes the reflection include the following: C. a reflection over the line x = 3.
What is a reflection?In Mathematics, a reflection can be defined as a type of transformation which moves every point of the geometric figure such as a triangle, by producing a flipped, but mirror image of the geometric figure.
Based on the graph of triangle ABC and triangle ΔA’B’C’, we can logically deduce the following coordinates after a reflection over the line x = 3:
A = (-2, 2) → A' = (8,2)
B = (0, 4) → B' = (6, 4)
C = (2,2) → C' = (4, 2)
Therefore, the two triangles are identical (similar) because they are reflections of each other. Also, the distance between the point C and point C' is 2 units, therefore, with a line that is parallel to the y-axis and lies at point x = 3, as shown in the image attached below.

a.)A reflection over the line x = 2
b.)A reflection over the line y = 3
c.)A reflection over the line x = 3
d.)A reflection over the y-axis
Answer:
The correct answer is:
You can map ABC to A'B'C' by translating it 6 units left and reflecting it across the x-axis, which is a series of rigid motions.
Explanation:
In ABC, the coordinates are:
A(1, -3)
B(5, 3)
C(4, -1).
In A'B'C', the coordinates are:
A'(-5, 3)
B'(-1, -3)
C'(-2, 1)
Each point is mapped to its image:
A(1, -3)→A'(-5, 3)
B(5, 3)→B'(-1, -3)
C(4, -1)→C'(-2, 1
Comparing the x-coordinates in the pre-image and image, we notice that the image has an x-coordinate that is 6 less than that of the pre-image:
1-6 = -5
5-6 = -1
4-6 = -2
This means that the figure must be translated 6 units left; that is the only way to have this change on the pre-image to form the image.
Comparing the y-coordinates of the pre-image with those of the image, we notice that they are negated:
-(-3) = 3
-(3) = -3
-(-1) = 1
This means the pre-image was reflected across the x-axis; this is the only way to negate the y-coordinate and not change the x-coordinate.
These are rigid motions because they do not change the shape or size, they simply move it and change its orientation.
