What is the area of a square with side lengths of 3/5 units?
15/15
9/25
6/10
3/5
Answer:
you get 9/25
Step-by-step explanation:
formula for area of square
=s^2
plug in
3/5^2
calculate
you get 9/25
Hey there!
To find the area of a square, multiply the side length by itself, also known as sqaring the side length.
We must solve 3/5 x 3/5.
3/5 x 3/5 = 0.36
The units we'll use is because units are the unt we're given, and it is squared because it is the area of a shape.
Your final answer is 0.36 .
Hope this helps!

Determine the missing side length!!
PLEASE NO CAP!!
Answer:
missing side length = 9
Step-by-step explanation:
[tex]c^{2} = a^{2} + b^{2}[/tex]
a = 6
b = 7
c = missing side
[tex]c^{2} = 6^{2} + 7^{2}[/tex]
[tex]c^{2} = 36 + 49[/tex]
[tex]c^{2} = 85[/tex]
[tex]\sqrt{c^{2} } = \sqrt{85}[/tex]

44 students decided to take a cupcake, and 33 of them picked vanilla. What percentage of the students picked
Answer:
33.33%
Step-by-step explanation:
Given data
Total number of students= 44
Number of students that picked vanilla= 33
Therefore the percentage that picked vanilla is
=44-33/44*100
=11/33*100
=0.3333*100
=33.33%
Hence the percentage is 33.33%

The results of a series of surveys revealed a population with a mean of 4.73 and a standard deviation of 0.865. If each survey has a sample size of 200, which value falls within the interval where 95% of the sample means occur? A. 4.88 B. 4.63 C. 4.91 D. 4.55
Answer:
4.63
Please give me brainliest, I really need it.
The value of 4.63 falls within the interval (4.66, 4.791) where 95% of the sample means occur option (B) is correct.
What is a confidence interval for population standard deviation?It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.
The formula for finding the confidence interval for population standard deviation as follows:
[tex]\rm s\sqrt{\dfrac{n-1}{\chi^2_{\alpha/2, \ n-1}}} < \sigma < s\sqrt{\dfrac{n-1}{\chi^2_{1-\alpha/2, \ n-1}}}[/tex]
Where s is the standard deviation.
n is the sample size.
[tex]\chi^2_{\alpha/2, \ n-1} and \chi^2_{1-\alpha/2, \ n-1}[/tex] are the constant based on the Chi-Square distribution table.
α is the significance level.
σ is the confidence interval for population standard deviation.
Calculating the confidence interval for population standard deviation:
We know significance level = 1 - confidence level
It is given that:
Mean of the population x = 4.73
Standard deviation s = 0.865
Sample size n = 200
The interval where 95% of the sample means occur:
Lower limit = 4.73 - 0.865/√200
Lower limit = 4.66
Upper limit = 4.73 + 0.865/√200
Upper limit = 4.791
The interval = (4.66, 4.791)
Thus, the value of 4.63 falls within the interval (4.66, 4.791) where 95% of the sample means occur option (B) is correct.

What is the data range of the data below 625, 638, 619, 677, 638, 659
Answer:
58
Step-by-step explanation:
The range is the difference between the highest and the lowest numbers in the number set.
The highest number in this set is 677 and the lowest number is 619.
677 - 619 = 58
Isabella has 63 hair bows. Isabella's sister has h more hair bows than Isabella. Choose the expression that shows how many hair bows Isabella's sister has.
Answer:
(h+63)
Step-by-step explanation:
Given that,
Isabella has 63 hair bows.
Isabella's sister has h more hair bows than Isabella. It means,
Isabella's sister = h+63
h and 63 are added as Isabella's sister has h more hair bows than Isabella.
Hence, the expression would be (h+63).

4) What is the probability to draw a black checker from a bag of 6 black
checkers and 4 red checkers, replacing it and drawing another black checker.
Step-by-step explanation:
Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.
A helicopter flew north 325 meters and then flew east 500 meters. How far is the helicopter from its starting point?
Answer:
596.34m approx
Step-by-step explanation:
Given data
Let the Starting point be x
A helicopter flew north 325 meters from x
Then flew east 500 meters
Let us apply the Pythagoras theorem to solve for the resultant which is the distance from the starting position
x^2= 325^2+500^2
x^2=105625+250000
x^2= 355625
x= √355625
x=596.34m
Hence the distance from the starting point is 596.34m approx

Which set of ordered pairs represents y as a function of x?
Answer:
D is the correct answer
Explanation:
the following function satisfies each output to its input for the set D
f(x)=x/2
let's check each pair:
0/2=0
-1/2=-0.5
-2/2=-1
-3/2=-1.5
-4/2=-2
the reason why A, B, and C can't be pairs of inputs and outputs x and y it's because a variable x can't have more than one y (that's a behaviour of an equation not a function!)
- in A x=-1 | y=2, -2 and this wrong
- in B x=3 | y=9, 16 and this wrong
- in C x=0 | y=0, 1 and this wrong

Which number, when raised to the power of 5, equals 2?
Answer:
1.148698
Step-by-step explanation:
The number that will be equal to 2 when raised to the power of 5 is 1.1487.
When raising a particular number to the power of another, It implies that we are multiplying that particular number in the number of places with which the power is being raised.
From the given information:
Let the unknown number be x;SO;
x⁵ = 2We will need to determine the fifth root of 2 in order to eliminate the power of 5 in x.
i.e
[tex]\mathbf{ \sqrt[5]{x^5}=\sqrt[5]{2} }[/tex]
[tex]\mathbf{ x=\sqrt[5]{2} }[/tex]
x = 1.1487
Therefore, we can conclude that the number that will be equal to 2 when raised to the power of 5 is 1.1487.
