0.5 + 6.38= 6.88

In general you'd round your answer to the greatest level of precision used in the question, not the least.

The statement is false. The explanation is given.

Decimals are numbers that have two components, a whole number component and a fractional component, which are separated by a decimal point.

Given:

A phrase: 0.5 + 6.38= 6.9 because 0.5 is precise to the tenth digit, so the answer must also be rounded to the nearest tenth.

0.5 + 6.38 = 6.88

To round the decimals:

Round the prior digit down if the final digit is less than 5. However, you should round the preceding figure up if it is 5 or above.

6.88 = 6.9.

Therefore, the statement is false.

The midpoint of a line segment partitions the line segment into a ratio of 1:1, meaning it divides the segment into two equal parts.

In mathematics, a midpoint refers to a point that is exactly in the middle of a line segment. The definition of midpoint implies that it divides or partitions a line segment into two equal parts. Therefore, the ratio is 1:1.

Consider the given line segment AB with the midpoint M. If the length of the segment AB is L, then AM = MB = L/2. This shows that the line segment AB is divided into two equal parts by M, thus resulting in a 1:1 ratio.

https://brainly.com/question/28224145

#SPJ2

The correct answer is 1:1.

The midpoint of a line segment is the point that divides the segment into two equal parts. By definition, these two parts are of the same length, which means that the ratio of their lengths is 1:1. This is because the midpoint is equidistant from both endpoints of the line segment, effectively splitting the segment into two congruent segments.

To illustrate this with an example, let's consider a line segment AB with a midpoint M. The length of segment AM is equal to the length of segment MB. If we denote the length of AM as x and the length of MB as y, we have:

x = y

Expressing this as a ratio, we get:

x/y = 1/1

This ratio represents the division of the line segment by its midpoint, and it shows that the division is equal on both sides of the midpoint, hence the ratio of 1:1.

The situations that show strong correlation are;

1), 3), 4)

Step-by-step explanation:

To answer the question, we analyze each of the options in turn as follows

1) Since the speed of a car is given by the distance covered per unit time or speed = distance/time then, speed is inversely proportional to time that is an increase in speed will lead to a decrease in time to cover a given distance hence there is a strong correlation implying causation

2) Here, we have that the profit of the company is the difference between the total revenue and the total cost hence;

Profit = Revenue - Cost

As advertising is a cost, increasing the advertising budget, increases the cost and where the revenue remains, constant the profit will decrease

Therefore there is no correlation between increasing the advertising budget and increase in profit

3) When the weather is hot, people get thirsty and will like to cool down their body temperature, hence more people buy ice cream to cool down and quench some thirst hence there is a strong correlation between increase in temperature and an increase in ice cream sales which implies  causation

4) For very low income employments, some employees seek excuses to try to make the most of their time hence whereby it is difficult to have another employee stand in for them, some employees may select the recognized excuse of being sick so as to explain absence from work, hence when the salary is increased, they will find more reasons to come to work hence there is a strong correlation between increase in salary and decrease in sick days.

Answer:

D.) 73.7

Step-by-step explanation:

Took it on edge

The measure of angle B= 73.739.

Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles. The ratios used to study this relationship are called trigonometric ratios, namely, sine, cosine, tangent, cotangent, secant, cosecant.

There are basic six ratios in trigonometry that help in establishing a relationship between the ratio of sides of a right triangle with the angle. If θ is the angle in a right-angled triangle, formed between the base and hypotenuse, then

given:

AC= 24, BC= 25

Now,

The opposite is the side facing the angle while the adjacent is the other third side.

Using Trigonometry

sin B = P/B

sin B= 24/25

sin B= 0.96

B= arc sin(0.96)

Correct choice is the second one

Answer:

Theta =  120 degrees, 420 degrees, 480 degrees, 780 degrees, and 840 degrees

60 + 360 = 420 degrees,  

60 + 720 = 780 degrees,  

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

Step-by-step explanation:

90  to 870 degrees for theta.

sin (theta) = root(3) /2

We see this comes from a 30-60-90 triangle.

theta is 60 degrees

but we want theta from 90 to 870 degrees.

120 degrees works too.

so we try to find all the co-terminal angles to 60 and 120 degrees that satisfy the conditions.

60 + 360 = 420 degrees,  

60 + 720 = 780 degrees,  

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

Answer:

A,B,D

Step-by-step explanation:

"The correct statements about the angle relationships in rectangle ABCD are:

- AngleBEA and AngleCED are vertical angles and equal 76°.

- AngleABE and AngleCBE are complementary angles.

- AngleBEC and AngleCED are vertical angles.

- AngleBEA and AngleAED are supplementary angles whose sum is 180°.

- AngleBEC and AngleAED are adjacent angles.

1. AngleBEA and AngleCED are vertical angles. Vertical angles are the angles opposite each other when two straight lines intersect. Since BD and AC intersect at E, angle BEC and angle AED are vertical angles and therefore equal. Given that angle BEC is 52 degrees, angle AED is also 52 degrees. However, the question states that angle DAE is 104 degrees, which means angle AED is 180 - 104 = 76 degrees (since angle DAE and angle AED are supplementary angles as they form a straight line). Therefore, angle CED is also 76 degrees, not 52 degrees as initially stated. This corrects the inaccuracy in the question.

2. AngleABE and AngleCBE are complementary angles. Complementary angles are two angles whose measures add up to 90 degrees. Since ABCD is a rectangle, angle ABE and angle CBE are right angles (90 degrees). Angle ABE is made up of angles ABE and BEC, and since angle BEC is 52 degrees, angle ABE is 90 - 52 = 38 degrees. Similarly, angle CBE is made up of angles CBE and BEC, so angle CBE is also 38 degrees. Therefore, angles ABE and CBE are complementary as their sum is 90 degrees.

3. AngleBEC and AngleCED are vertical angles. As previously explained, vertical angles are equal, so angle BEC and angle CED are equal, both being 52 degrees.

4. AngleBEA and AngleAED are supplementary angles. Supplementary angles are two angles whose measures add up to 180 degrees. Since angle BEC is 52 degrees and angle BEC and angle BEA are adjacent angles, angle BEA is 180 - 52 = 128 degrees. Angle AED is 76 degrees as previously calculated. Adding angle BEA and angle AED gives us 128 + 76 = 204 degrees, which is incorrect. The correct calculation should be that angle BEA is 76 degrees (as it is vertical to angle CED which is 76 degrees), and angle AED is 104 degrees (as given in the question). Therefore, angle BEA and angle AED are supplementary as their sum is 76 + 104 = 180 degrees.

5. AngleBEC and AngleAED are adjacent angles. Adjacent angles share a common side and a common vertex. In this case, angle BEC and angle AED share side AE and vertex E. This statement is true as they are indeed adjacent angles."

Step-by-step explanation:

Answer:

5. y = 2x + 4

6. y = (-1/2)x - 2

Step-by-step explanation:

5. We want to find the slope-intercept form of this, which is y = mx + b, where m is the slope and b is the y-intercept.

Slope is change in y divided by change in x. Here, let's take two random points: (-2, 0) and (0, 4). Then we have:

m = (4 - 0) / (0 - (-2)) = 4 / 2 = 2

The slope is thus 2.

The y-intercept is where the line crosses the y-axis. We see it does so at the point (0, 4), so b = 4.

Our equation is thus: y = 2x + 4.

6. Again, let's find the slope. Pick any two points: (-4, 0) and (0, -2). The slope will be:

m = (-2 - 0) / (0 - (-4)) = -2 / 4 = -1/2

Now, look at the point (0, -2); that's where the line crosses the y-axis, so the y-intercept is b = -2.

Thus, the equation is: y = (-1/2)x - 2.

Answer:

5. y = 2x + 4

6. y = -0.5x - 2

Step-by-step explanation:

5. Slope: (4-0)/(0--2) = 4/2 = 2

y-intercept: 4

y = 2x + 4

6. slope: (-2-0)/(0--4) = -2/4 = -0.5

y-intercept: -2

y = -0.5x - 2
