Is the function linear? How do you know?
find the corret measure of 6
Answer:
∠3 = 102°
Step-by-step explanation:
║A straight line always equals 180°. So all we need to do is subtract 78° ║from 180° for the missing angle.
180 − 78 = 102
∠3 = 102°
Further explanation:
║The image shows two slanted lines across one vertical line. If we visualize ║a circle around the point where the slanted line intercepts with the vertical ║line, we can solve this.
[we only need one line to work with, because both lines are parallel]
║That circle you visualized divides the intercept into four sectors. One of ║those sectors, or angles, is labled 78°. We need to find the angle measure ║underneath the labled sector. The sector in the bottom right corner has ║the same angle measure as the labled sector, which is 78°. The sector ║labled ∠3 has the same angle measure as the sector in the upper right.
[a full rotation around an angle is always 360°]
║This can be easily solved by subtracting 78° from 180° to get the angle ║measure for the upper right sector, which is equivalent to ∠3. Using basic ║subtraction, 180° − 78° = 102°. We can prove this by multiplying 78° by 2, ║multiplying 102° by two, and adding the products.
78 ⋅ 2 = 156
102 ⋅ 2 = 204
204 + 156 = 360
║Because the sums equal 360°, we can determine the answer is true.

Which best explains why an iceberg floats? Water expands and becomes denser when it freezes. Water contracts and becomes denser when it freezes. Water expands and becomes less dense when it freezes. Water contracts and becomes less dense when it freezes.
Answer: Water expands and becomes less dense when it freezes.
Step-by-step explanation:
When a solid is less dense than liquid that it is put in, it will float.
This is the case with icebergs. When water freezes, the molecules move away thereby expanding and increasing the volume of the water.
The larger the volume of an object, the smaller it's density.
The iceberg will therefore have a lower density that enables it to float.
Answer:
C: Water expands and becomes less dense when it freezes.

When rounding to the nearest hundred thousand, the weight of a blue whale was rounded to 500,000 pounds. What is the least the blue whale could actually weigh?
Answer:
450,000 pounds
Step-by-step explanation:
to round off to the nearest hundred thousand, look at thousand figure - If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
to be rounded off to 500,000, it means that the thousand figure has to be between 50,000 - 99,000
the least figure would thus be 450,000

What is 50% of 40
Thank you
Answer:
20
50% of 40 is 20 because half of 40 is 20
Answer:
20
Step-by-step explanation:
1) Change 50% into a decimal
50% ⇒ 0.5
2) Multiply 0.5 by 40
0.5 × 40 = 20
Therefore, 50% of 40 is 20.

A salesman who is on the road visiting clients thinks that, on average, he drives the same distance each day of the week. He keeps track of his mileage for several weeks and discovers that he averages 122 miles on Mon- days, 203 miles on Tuesdays, 176 miles on Wednesdays, 181 miles on Thursdays, and 108 miles on Fridays. He wonders if this evidence contradicts his belief in a uni- form distribution of miles across the days of the week. Explain why it is not appropriate to test his hypothesis using the chi-square goodness-of-fit test.
Answer:
The conditions are not met.
Step-by-step explanation:
The conditions for the chi square test for goodness of fit are
1) the sample is a random sample
2) the variable under study is categorical
3) all expected value of the number of sample observations are greater or equal to 5.
A)The observations must be independent
B) for 2 categories the expected values must be at least 5
C) for the 3 categories the expected values must be at least 1 and no more than 20% may be smaller than 5
The observations given may not be independent i.e have equal chances of occurrences or are maybe dependent on each other in the sense that there maybe a limit for his traveling mileage or the a limit for petrol ( fuel ) usage . So if he is required to drive 500 miles in a week each day mileage depends on the other day mileage .
Also we are given the information that keeps track of his mileage for several weeks, but we are not sure if several refers to more than 5 .
As both conditions are not clearly satisfied it is not appropriate to test his hypothesis using the chi-square goodness-of-fit test.
The sample must also be a random sample.
Here he has taken the mean of all the days.
