Answer:
623.61 cm³
Step-by-step explanation:
Given:
Radius of sphere (r) = 5.3 cm
Required:
Closest volume of the ball
SOLUTION:
Volume of a sphere = ⁴/3πr³
Radius (r) = 5.3 cm
Plug in the value of r
Volume = ⁴/3*π*5.3³
Volume = ⁴/3*π*148.877
Volume = 623.61 cm³
623.61 cm³ is closest to the volume of the ball.
Multiply.

Answer:
1 : 3
Step-by-step explanation:
¼ of the biscuits are chocolate while the rest are plain.
Since a fraction is a part of a whole, 1, then it means that the fraction that are plain is:
1 - ¼ = ¾
Therefore, the ratio of chocolate biscuits to plain biscuits is:
¼ : ¾
To put this in simplest dorm, multiply both sides by 4, we have:
1 : 3
This is the ratio of chocolate biscuits to plain biscuits.

Find the standard equation for the circle with center on the negative y -axis and passing through the origin with radius of 3.
A. x^2 + y^2 = 9
B. (x + 3)^2 + y^2 = 9
C. x^2 + (y + 3)^2 = 9
Answer:
The correct option is C : x² + (y +3)² = 9 .
Step-by-step explanation:
We know that the general equation for a circle is ( x - h )² + ( y -k )²= r², Where,
r is the radius.(h , k) is the center.Let the point be ( 0 , -y) , since it is on negative y axis . And the circle passes through the origin that is (0,0) . Hence the center will be 3 units down the y - axis that is ( 0 , -3) .Hence h will be 0 and y = (-3) .
Now its given that the radius of the circle is 3. So on substituting r = 3 , in standard form we have ,
⇒ ( x -h )² + ( y - k )²= r²
⇒ ( x - 0)² + { y - (-3) }² = 3²
⇒ x² + ( y + 3) ² = 3²
⇒ x² + ( y + 3)² = 9
Hence the correct option is C [ x² + ( y+3)² = 9 ] .Note that I have attached the graph of the same .

Monique works for h hours as a lifeguard this week, earning $12 per hour she also earns $20 for dog city which expression represents how much money Monique will make this week
The total money earned by Monique can be written as a expression as 12h + 20.
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The earning per hour working as lifeguard is $12.
And, the earning from dog city is $20.
Suppose the number of hours worked as lifeguard be h.
Then, the money earned working as lifeguard is 12h.
Now, the expression for total money earned can be given as,
12h + 20
Hence, the expression for the total earning can be given as 12h + 20.

A local grocery delivery time has a uniform distribution over 15 to 65 minutes. What is the probability that the grocery delivery time is more than 20 minutes on a given day
Answer:
The probability is 0.9
Step-by-step explanation:
We start by calculating the density function
That will be;
f(x) = 1/(b-a)
b and a are the extremes
from the question,
a = 15
b = 65
So f(x)
= 1/(65-15) = 1/50 = 0.02
The probability we want to calculate is;
P( x > 20)
The termination point is 65
So the probability will be
(65-20) * 0.02
= 0.9
XLiV represents 64 true ya false
Answer:
False
Step-by-step explanation:
Given
[tex]XLIV = 64[/tex]
Required
True or False
The above numeral can be split as follows:
[tex]XLIV = XL + IV[/tex]
X means 10 and L means 50.
But because X (10) which is smaller comes before L (50), XL is executed as:
[tex]XL = -10 + 50[/tex]
[tex]XL = 40[/tex]
In Roman numerals;
[tex]IV = 4[/tex]
Substitute 40 for XL and 4 for IV.
[tex]XLIV = 40 + 4[/tex]
[tex]XLIV = 44[/tex]
Hence;
[tex]XLIV = 64[/tex] is false
Consider a situation in which sampling without replacement is used to generate a random sample from each of two separate populations. To calculate a confidence interval to estimate the difference between population proportions, which of the following checks must be made?
Answer:
Each population must be at least 10 times as large as its corresponding sample.
Step-by-step explanation:
The 10 percent rule checks that the sample is small relative to the population (that is, that the population is at least 10 times as large as the sample size) so that independence of observations within a sample is reasonable to assume.
The check that must be made is (b) Both population must be approximately normal
From the question, we have the following highlights
The sampling is without replacementThere are separate populationsWhen the above highlights are true, then the population where the samples are to be selected must be approximately normal
Hence, the check that must be made is (b) Both population must be approximately normal

(5a^2b^3)(6a^kb)=30a^6b^4
o 2
O 3
O4
O 8
helpppp !
Answer:
4
Step-by-step explanation:
(5a^2b^3)(6a^kb) = 30a^6b^4
a^2 * a*k = a^6
a^(2 + k) = a^6
2 + k = 6
k = 4
Answer: 4
The value of k from the equation is k = 4
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
( 5a²b³ ) ( 6a^k )b = 30a⁶b⁴
On simplifying , we get
From the laws of exponents , we get mᵃ×mᵇ = mᵃ⁺ᵇ
So , ( 30a^( 2 + k ) ) b⁴ = 30a⁶b⁴
Divide by 30b⁴ on both sides , we get
a^( 2 + k ) = a⁶
Now , the bases of the exponents are same ,
So , 2 + k = 6
Subtracting 4 on both sides , we get
k = 4
Therefore , the value of k = 4
Hence , the exponential equation is solved
