Suppose there is a 1.9°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 54.7°F, what will be the temperature when the plane reaches an altitude of 4,000 ft?
4000/1000 = 4
There are 4 drops in temperature.
1.9 x 4 = 7.6 total temperature drop.
54.7 - 7.6 = 47.1 F temperature
1.9 x 4 = 7.6 total temperature drop.
54.7 - 7.6 = 47.1 F temperature
A history teacher gives a 19-question true-false exam. In how many ways can the test be answered if the possible answers are T or F or possibly to leave the answer blank?
38 because there are 2 choices true or false so if there are 19 questions each question would have 2 choices and if selected both same with all the other ones if there are 19 questions each and 2 choices for each question then multiply it by 19*2 and you get 38. Simple!

Juniper drives at a constant speed on the highway towards Exit 34. The graph below shows the distance, in miles, that Juniper is from Exit 34 over time.
——————————
The slope of the graph is
60.
The y-intercept gives the initial distance, in miles, from Exit 34.
The y-intercept of the graph is
3.5.
The slope gives the rate, in miles per hour, at which the distance to Exit 34 changes over time.
Answer:
Options (2) and (4)
Step-by-step explanation:
Option (1)
The slope of the graph is 60.
From the graph attached,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-210}{3.5}[/tex]
= - 60
False.
Option (2)
y-intercept gives the initial distance, in miles from Exit 34.
True.
Option (3)
y-intercept of the graph is 3.5
Since, y-intercept of the graph is 210.
Therefore, Option (3) is False.
Option (4)
Slope gives the rate, in miles per hour, at which the distance to Exit 34 changes over time.
True.
A __________ is a claim or assertion either about one or more population or process characteristics (parameters) or else about the form of the population or process distribution.
Answer:
statistical hypothesis.
Step-by-step explanation:
A statistical hypothesis has the central objective of assisting in a decision-making process about one or more populations in relation to the sample data, allowing the observance of whether the information found in the samples will support the statistical hypothesis.
It is necessary to know concepts of mathematical probability to perform the tests, the most used models for this purpose are the fisher method, by Neyman-Pearson and Bayes.
The variables used in a statistical hypothesis are: the Null Hypothesis, the one that is assumed to be the true one, the Alternative Hypothesis, the one that is used when there is no statistic to analyze the hypothesis given as true, the Type I Error, related to the probability of rejection of the null hypothesis, and the Type II Error, which is the probability of rejection of the alternative hypothesis if it is true.

Two natural numbers differ by 1 and add to give 35. Find the smaller number. google it and answer will come,I just need answer pls.. It is blocked on my school chromebook soo...
Answer:
17
Step-by-step explanation:
Since the numbers differ by 1, you can write the smaller number as x and the bigger one as x+1.
When you add them together you get 35: x+x+1=35
This simplifies to 2x+1=35.
When you solve you get 2x=34 so x=17.

At a local department store, skirts typically cost $15. However, due to a special, the
skirts are reduced to $3. What percent of the original price has the skirts been reduced
to?
Answer: 20%
Step-by-step explanation:
(part / whole) * 100
(3 / 15) * 100 = 20%
The skirts have been reduced to 20% of their original price.
You are looking for the percentage of the original price that the new price is. This means that you are looking for what percentage of $15 that $3 is:
= New price / Original price x 100%
= 3 / 15 x 100%
= 1/5 x 100%
= 20%
The skirts have therefore been reduced to 20% of their original price.

this answer will not be found on brainly because on flvs they mix them up
Answer:
A .x+y=150 y=x+80
B. x=35 y=115
x + (x + 80) = 150
2x + 80 = 150
2x = 70
x =35 practicing the guitar
then put x back in to solve for y
C. no because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.
Step-by-step explanation:
this is my first time answering a question so hope it helps :)
A pair of linear equations to show the relationship between the number of minutes ;
x=Max practices the guitar
y= the number of minutes he practices the piano
Pair of equation are :x+y=150
y=x+80
Part B:The time does Max spend practicing the piano every day:
x=35 y=115 x + (x + 80) = 150 2x + 80 = 150 2x = 70 x =35Subsitute x back in to solve for y.
x+y=150
35+y=150
y=115
Part C:No , it is not possible because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.

Rachel ate 1/8 of the pepperoni pizza and 1/4 of the cheese pizza. How much of a pizza did she eat?
Answer:
3/8
Step-by-step explanation:
1/4 = 2/8
1/8 + 2/8 = 3/8
Rachel ate 3/8 of the pizza in total from pepperoni pizza and cheese pizza.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Rachel ate 1/8 of the pepperoni pizza and 1/4 of the cheese pizza.
The total pizza eaten will be calculated as,
1/4 = 2/8
1/8 + 2/8 = 3/8

1. A newborn giraffe weighs about 65 kilograms. How much does it weigh in grams?
65 kg = 65*1000 g = 65000 g2. The average height of a female giraffe is 4.6 meters. What is her height in centimeters?
4.6 m = 4.6*100 cm = 460 cm3. The capacity of a beaker is 0.1 liter. Convert this to milliliters.
0.1 l = 0.1*1000 ml = 100 ml4. A pig weighs 9.8 pounds. Convert the pig’s weight to ounces.
9.8 pounds = 9.8*16 ounces = 156.8 ounces5. A marker is 0.13 meters long. What is the length in millimeters?
