Find the distance between the two points rounding to the nearest tenth
(if necessary).
(-7, -6) and (-3,2)
Submit Answer
Answer:
Answers
Answer:
8.9
Step-by-step explanation:
To solve this problem you just use the distance equation which is √((x1-x2)^2+(y1-y2)^2). It does not matter which point you use where but if you use -7 as your x1, you have to use -6 as your x1.
The process should look like this
√(-7-(-3))^2+(-6-2)^2)
√((-4)^2+(-8)^2)
√(16+64)
√(80)
=8.944 or 8.9 rounded to the nearest tenth

What is the radius of the copper circle?
Answers
9514 1404 393
Answer:
(1+√2)/2 ≈ 1.207 cm
Step-by-step explanation:
The angled flats are at 45°, so the length in the direction of a vertical or horizontal radius is (1 cm)/√2 = (1/2)√2 cm. The remaining length of that radius is half the length of a flat, so is 1/2 cm. The total length of the radius is ...
1/2 + 1/2√2 = (1+√2)/2 ≈ 1.207 cm
_____
In trigonometry terms, the length of the flat is ...
1 cm = 2(r)(tan(45°/2))
so the radius is ...
r = (1 cm)/(2·tan(22.5°))
r = (1/2)cot(22.5°) ≈ 1.207

Sophie invested 5,000 into an account that will increase in value by 2.3% each year. Write a function to model this situation, then find the value of the investment after 15 years
Answers
Answer:
$6725
Step-by-step explanation:
Given data
Princiapal= $5000
Rate=2.3%
Time= 15years
The function that will model this situation is given as
A=P(1+rt)
The above function is a simple interest function
Substitute our data we can find the amount A
A=5000(1+0.023*15)
A= 5000(1+0.345)
A=5000(1.345)
A=5000*1.345
A=$6725
Hence the value of the investment after 15 years is $6725

According to the American Academy of Ophthalmology, 25% of Americans have brown irises. A random survey of students at a local community college found that 58 out of 175 had brown irises. What is the test statistic (ie the Z score) for this sample of students
Answers
Answer:
2.49
Step-by-step explanation:
Given X= 58
N = 175.
P = 25% = 0.25.
[tex]P' = \frac{X}{N} = \frac{58}{175} = 0.3314\\Z = \frac{P'-P}{\sqrt{\frac{pq}{N} } }[/tex]
Now plugging the values we get
[tex]= \frac{0.3314-0.25}{\sqrt{\frac{0.25\times0.75}{175} } }[/tex]
=2.49

Answers
Answer:
D.2
Step-by-step explanation:
The z-score of an appliance that stopped working at 64 months is 2
What is z score?Standard score or z score in statistics is defined as the number of standard deviations by which that the value of a score is above or below the mean value.
The formula to find the z score of a data is,
z = (x - μ) / σ
Here x is the observed value, μ is the mean and σ is the standard deviation.
Given that,
Mean = 48 months
Standard deviation = 8 months
x = 64 months
Substituting in the formula,
z = (64 - 48) / 8 = 2
Hence the z score of the appliance is 2.

Explanation:
So, what we need to do is to separate that triangle at the too from the rectangle.
Now we have two shapes.
Lets find the are of the triangle:
The height of the triangle is 7, which is perpendicular to the base.
The base is going to be also 20 because its the same length as the rectangle’s.
The formula for the are of a rectangle is
1/2 x Base x height (1/2 x 20 x 7) which is equal to 70 square units.
The area of the triangle is 100 square units (20 x 5)
We add the area of the shapes:
100 square units + 70 square units= 170 square units

Answer:
33°
Step-by-step explanation:
<ACD =90-33 =57°
<DCB=<ACB - <ACD
=90° -57 =33°
In triangle ACD the only angle that has not been found is <ACD so you find it by adding 90+33 and subtracting from 180° to get 57°. <ACB =90° and <ACD = 57° ,the angle in question is<DCB which is part of< ACB. So to get <DCB you do 90°-57°=33°.
B = 180 - 90 - 33 = 57°
C in DCB tringle = 180 - 90 - 57 = 33°
So C in DCB triangle = 33°

o A. 80
OB. 86
O C. 98
O D. 70
Answers
Using the given percentage, we found that the total number of chocolate chip muffins sold is 80.
What is meant by percentage?
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Frequently, it is indicated with the per cent sign, "%". If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word per cent means. A % is a number without dimensions and without a standard measurement. The value of "whole" in this relationship between portion and whole is always set at 100.
Given,
the number of chocolate chip muffins sold = 36
The 36 muffins is the 45% of the total muffins sold.
Let the total number of muffins sold be x.
Then using the given percentage, we find the total muffins sold.
Percentage = (required number of muffins sold/ total number sold) *100
45% = 36/x * 100
0.45 = 36/x
x = 36/0.45 = 80
Therefore using the given percentage, we found that the total number of chocolate chip muffins sold is 80.
