during the volleyball match, maddie had 8 serves that were inbounds and 5 that were out-of-bounds. what is the ratio of services that were inbounds to total serves
Answer:
[tex]R=\dfrac{8}{13}[/tex]
Step-by-step explanation:
Inbounds in the volleyball match = 8
Out of bounds in the volleyball match = 5
Total serves = inbounds + out of bounds
= 8+5
= 13
The ratio of services that were inbounds to total serves is given by :
[tex]R=\dfrac{8}{13}[/tex]
Hence, this is the required solution.

The Riemann sum, the limit as the maximum of delta x sub i goes to infinity of the summation from i equals 1 to n of f of the quantity x star sub i times delta x sub i , is equivalent to the limit as n goes to infinity of the summation from i equals 1 to n of f of the quantity a plus i times delta x, times delta x with delta x equals the quotient of the quantity b minus a and n. Write the integral that produces the same value as the limit as n goes to infinity of the summation from i equals 1 to n of the product of the quantity 2 plus 3 times i over n and 3 over n.

ayuda porfavor
Answer:
x = 9
Step-by-step explanation:
(x+1)²-(x-1)² = 6(x-3)
x²+2x+1-x²+2x-1 = 6x-18
x²-x²+2x+2x+1-1 = 6x-18
4x = 6x-18
4x-6x = -18
-2x = -18
x = -18/-2
x = 9

A six-sided die is rolled. What is the probability of landing on a number less than 3? Put our answer in simplest form.
Answer:
1/3
Step-by-step explanation:
2/6
1/3
Answer:
Probability of any one face to turn up is 1/6,
The probability of any above 3 is 3/6,
The probability of even number is also 3/6
So the probability of either above three or even outcome is 1/6(3/6 + 3/6)=1/6, since both events are independent of the any face event and both events are mutually exclusive.
NB:If the two events are not mutually exclusive, then
P(A) is the total event, P(B) the probability of any face above 3 and P(C) probability of any face an even number, then the Bayesian prediction formula is P(B|C) the probability of the event B occuring while C occurs is equal to (PC|P(B))/(P(B)+P(C), where P(C|B) is probability of C occuring at B.
So P(B|C)=(1/3 * 1/3)/(1/3 + 1/3) =(1/9)/(2/3) = 3/18= 1/6.

a) Draw the graph of y = 4x - 1
on the grid.
o
b) Use the graph to estimate the
value of x when y = 1
a) The graph of y = 4x - 1 is shown in attached image.
b) By using the graph at y = 1 the value of x is 1/2.
What is Linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The function is,
y = 4x - 1
Now, The graph of function y = 4x - 1 is shown in image.
And, At y = 1;
By the graph the value of x = 1/2.
And, In mathematically;
At y = 1
The value of x is;
y = 4x - 1
1 = 4x - 1
4x = 2
x = 2/4
x = 1/2
Thus,
a) The graph of y = 4x - 1 is shown in attached image.
b) By using the graph at y = 1 the value of x is 1/2.

L is in the interior of ∠JKM. If m∠JKL=56.4° and m∠JKM=82.5°, what is m∠LKM?
The measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees
The point where two lines meet or intersect is known as an angle.
If L is in the interior of ∠JKM, then:
∠JKL + ∠LKM = ∠JKM
Given the following parameters
m∠JKL=56.4° and m∠JKM=82.5°
Required angle
m∠LKM
From the expression above:
m∠LKM = ∠JKM - ∠JKL
m∠LKM = 82.5 - 56.4
m∠LKM = 26.1 degrees
Hence the measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees
