Answer: 2x=74
Step-by-step explanation:
Every triangle is 180 degrees.
so you will take 180-32= 148
then with that you will add up the x's and there are 4...
so then you will take 148/4 and get the answer of...
148/4=37
x=37
but it asked for 2x
37*2
2x=74
final answer is 74
Answer:
$0.60
Step-by-step explanation:
The costs are:
$0.15 + $0.25 = $0.40
He sells it for $1.25.
The value added is:
$1.25 - $0.40 = $0.85
Answer:
Hello! answer: 17
Step-by-step explanation:
Assuming this is the Pythagorean theorem our formula would be
a^2 + b^2 = c^2
meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...
15 × 15 = 225 8 × 8 = 64 225 + 64 = 289
the square root or the (number multiplied byitself that equals 289) is 17 because
17 × 17 = 289 so × = 17 I hope that helps!
Answers:
A: 11(2x-1)
B: 121 cupcakes
Step-by-step explanation:
<u>Part A: </u>
We have the following expression that models the quantity of cupcakes Mrs. Jones baked last week:
Applying distributive property:
Grouping similar terms:
Applying common factor 
:
This is the simplified expression

:
Hence, Mrs. Jones baked 121 cupcakes last week
Answer:
Step-by-step explanation:
Ok, so we have to help your pupil (lets call her Jane) figure out "why researchers should use a random sample to conduct a survey". So, i will list all of the choices.
- A random sample is likely to avoid bias
- In a random sample some members of the population are more likely to be selected than others
- Random samples provide consistency and systematically favor one choice over every other choice in each survey question
- Random sampling will provide a more representative sample of population
- Researchers can use a random sample to draw conclusions about the population
Random sampling is used to get the best average, and not favor any one opinion. For example, if you were trying to figure out the daily spending budget of people, you wouldn't just go to the upper clas part with all the rich people, you would survey from all over the town to get results from all kinds of people. So, the answers are:
- A random sample is likely to avoid bias (because thats exactly what they do)
- Random sampling will provide a more representative sample of population (because they are designed to do that)
- Researchers can use a random sample to draw conclusions about the population (thats why they take the samples)
Hope this helps
