What is square root of 28 approximated to the nearest tenth?

Answers

Answer 1
Answer: √28    use your calculator

≈ 5.2915

The tenth digit is 2, and the digit after the 2 is 9. 9 is more than 5, so we round up the 2 to 3.

≈ 5.3   to the nearest tenth.

The radius of a circle is a 1.6 calculate its circumference

Answers

Write down the formula for finding the circumference of a circle using the radius. The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr. In this formula, "r" represents the radius of the circle. Again, you can plug π into your calculator to get its numeral value, which is a closer approximation of 3.14.

Answer:

C≈10.05

if 4 bottles of juice were shared equally among 14 students, what fraction of the juice did each student drink

Answers

3 1/2. 14 ÷ 4 = 3.5. Now you know how much was divided between them in decimal form. To convert 3.5 to a fraction, put down 3 as the whole number and .5 as 5/10 because this decimal is read as "three and five hundredths." 3 5/10 is not in lowest terms, so you would divide both the numerator and the denominator by 5. 5 ÷ 5 = 1; 10 ÷ 5 = 2: 3 1/2 is your answer. Hope this helped!!! :)

Jasper is using the following data samples to make a claim about the house values in his neighborhood:House Value
A $150,000
B $175,000
C $200,000
D $167,000
E $2,500,000


Based on the data, should Jasper use the mean or the median to make an inference about the house values in his neighborhood?
He should use the mean because it is in the center of the data.
He should use the median because it is in the center of the data.
He should use the median because there is an outlier that affects the mean.
He should use the mean because there are no outliers that affect the mean.

Answers

Jasper should use the median to make an inference about the house values in his neighborhood.

What is Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

We have been given the house values in Jasper's neighborhood as:

House   Value

A           $150,000

B           $175,000

C           $200,000

D           $167,000

E           $2,500,000

Now, We can see the value of house E is very high from other houses in Jasper's neighborhood.

And, The value of house E will make the mean house value above the center of the data as House E is an outlier for our given data.

Since, We know that;

The median of a data set with an outlier is not affected by the value of outlier,

Therefore, Jasper should use the median to make an inference about the house values in his neighborhood.

Thus, Jasper should use the median to make an inference about the house values in his neighborhood.

#SPJ3
He should use the median because there is an outlier that affects the mean.

In this case, the outlier / 'extreme value' is E. We can see that most of the house prices are between $150,000 to $200,000, but E is much higher, therefore making it an outlier.

Madame Pickney has a rather extensive art collection and the overall value of her collection has been increasing each year. Three years ago, her collection was worth $500,000. Two years ago, the value of the collection was $550,000 and last year, the collection was valued at $605,000.Assume that the rate at which Madame Pickney’s art collection’s value increase remains the same as it has been for the last three years. The value of the art collection can be represented by a geometric sequence. The value of the collection three years ago is considered the first term in the sequence.
Write an explicit rule which can be used to determine the value of her art collection n years after that. Use this to determine the value of her collection 10 years after she started tracking its worth rounded to the nearest dollar.

Answer:

Value = 500000 × (1.1^n)

$1,296,871

Step-by-step explanation:

a = 500000

r = 550000 ÷ 500000 = 1.1

1st term is the initial year:

n years after that is the "n+1"th term

Value = 500000 × (1.1^n)

n = 10

500000(1.1¹⁰)

The figure is made up of a square and a rectangle. Find the area of the shaded region

Answers

first we do
squaer is legnth 6 so base =6
10-6=4
the rectnalge is 2 by 4
base=4


squaer is 6 by 6
rectangle is 4 by 2
split the triangles up
area of triangle=1/2base times height

rectangle triangle base=4
height=2, area=1/2 times 2 times 4=4

squaer triangle
flip 90 degrees clockwise so we have base=2
height=6
area=1/2 times 2 times 6=6

add
4+6=10
total area=10m^2
