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.

A six-sided die is rolled. What is the probability of landing on a number less than 3? Put our answer in simplest form.

Answers

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.

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

Answers

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 measures of two angles of a triangle are given. Find the measure of the third angle.
147° 12′, 30° 19′
51° 20′ 14″, 106° 10′ 12″

Example: Applying the Angle Sum of a Triangle Property
The measures of two of the angles of a triangle are 48° and 61°. See Figure 17.
Find the measure of the third angle, x.
SOLUTION 48° + 61° + x = 180° The sum of the angles is 180°.
109° + x = 180° Add.
x = 71° Subtract 109°.
The third angle of the triangle measures 71°.

L is in the interior of ∠JKM. If m∠JKL=56.4° and m∠JKM=82.5°, what is m∠LKM?

Answers

m∠LKM = 26.1°

Ffkdkdkkddkd

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
