Answer:

c. 4.7

Step-by-step explanation:

first, you find the mean of data set:

83 + 85 + 82 + 93 + 83 + 84 + 95 + 87 + 86 + 94 = 872/10 = 87.2

then, you take each number and subtract the mean and square it:

(87.2 - 83)² = (4.2)² = 17.64

(87.2 - 85)² = (2.2)² = 4.84

(87.2 - 82)² = (5.2)² = 27.04

(93 - 87.2)² = (5.8)² = 33.64

(87.2 - 83)² = (4.2)² = 17.64

(87.2 - 84)² = (3.2)² = 10.24

(95 - 87.2)² = (7.8)² = 60.84

(87.2 - 87)² = (0.2)² = 0.04

(87.2 - 86)² = (1.2)² = 1.44

(94 - 87.2)² = (6.8)² = 46.24

now, find the mean of the squared numbers:

17.64 + 4.84 + 27.04 + 33.64 + 17.64 + 10.24 + 60.84 + 0.04 + 1.44 + 46.24 = 219.6/10 = 21.96

then, take the square root of the number you just got:

√21.96 = 4.68

and last but not least, round to the nearest tenth: 4.7

There is no question asked, and the statement is incomplete, but this describes Series and Sequence. They are usually arithmetic or geometric progressions. A set of numbers are written to follow a particular pattern, when the pattern is clear, one can find any number of the sequence or series.

For example, consider the sequence below (Arithmetic Progression)

2, 4, 6, 8, ...

This sequence has a particular pattern.

The first term of the sequence is

a = 2

The common difference d, which is the difference between any two consecutive terms is

d = 2

The nth term, which is the formula that defines every single term of the sequence is given as

Tn = a + (n - 1)d

Check

T1 = a = 2

T2 = 2 + 2 = 4

T3 = 2 + 2(2) = 6

T4 = 2 + 2(3) = 8

T20 = 2 + 2(19) = 40

And so on.

Geometric progression

2, 4, 8, 16, 32, etc

First term, a = 2

Common ratio r, is the division of a particular number by the number preceding it.

r = 4/2 = 8/4 = 16/8 = 32/16 = 2

The nth term is given as

Sn = ar^(n-1)

S1 = a = 2

S2 = 2×2 = 4

S3 = 2×2^(2) = 8

S4 = 2×2^(3) = 16

S5 = 2×2^(4) = 32

S20 = 2×2^(19) = 1048576

And so on.

The exact probability that both marbles drawn will be red is 4/25.

Given that:

Number of red marbles in the bag, R = 8

Number of blue marbles in the bag, B = 7

Number of green marbles in the bag, G = 5

The total number of marbles in the bag is:

T = 8 + 7 + 5

   = 20

The probability of drawing a colored marble is the number of marbles of that color by the total number of marbles.

So, P(R) = 8/20, P(B) = 7/20 and P(G) = 5/20

If two marbles are drawn out of the bag, the probability that both marbles are red is:

P = P(R) P(R)

   = (8/20)(8/20)

   = (2/5)(2/5)

   = 4/25

Hence, the probability s 4/25.

Final answer:

The exact probability of drawing two red marbles from the bag without replacement is the product of the individual probabilities, calculated as (2/5) × (7/19).

Explanation:

To find the probability that both marbles drawn from a bag will be red, given the bag contains 8 red marbles, 7 blue marbles, and 5 green marbles, we need to calculate the probability of drawing one red marble and then another red marble without replacement.

The total number of marbles in the bag is 8 red + 7 blue + 5 green = 20 marbles. The probability of drawing the first red marble is 8/20, which simplifies to 2/5. After drawing one red marble, there are now 7 red marbles left and the total drops to 19 marbles. The probability of drawing a second red marble is now 7/19.

To find the probability of both events happening, we multiply the probabilities of each event: (2/5) × (7/19). Therefore, the exact probability of drawing two red marbles in succession without replacement is (2/5) × (7/19).

602.88 in ^ 3

Step-by-step explanation:

To calculate the volume of a cylinder, is the multiplication of the base area by the height the formula is as follows:

Vc = pi * (r ^ 2) * h

we have the necessary data, the radius equals 4 inches and the height equals 12 inches, replacing:

Vc = 3.14 * (4 ^ 2) * 12

Vc = 602.88 in ^ 3

that is, the volume of the oblique cylinder is 602.88 cubic inches

Answer:

The volume is 602.9in³

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cylinder

To find the volume of the oblique cylinder we use the formula for the volume of a cylinder

V= πr²h

Given data

Radius r = 4in

Height h= 12in

Substituting our given data we have V= πr²h

V=3.14*(4)²*12

V= 3.14*16*12

V= 602.88in³

To the nearest tenth

V= 602.9in³

Step-by-step explanation:

The original amount is 100% of the original amount since 100% means a whole amount.

A 21% increase means that the new amount will be 100% + 21% = 121% of the original amount.

Now we calculate 121% of 15,970.

To find a percent of a number, multiply the percent by the number. First, divide the percent by 100 to change it into a decimal.

Step-by-step explanation:

The 4th term in the sequence is -17.

To find the 4th term in the sequence defined by the recursive formula [tex]\(a(n) = a(n-1) - 5\)[/tex] with the initial condition [tex]\(a(1) = -2\)[/tex], you can use the recursive formula to compute each term. Let's find the first few terms:

1. [tex]\(a(1) = -2\)[/tex] (given)

2. [tex]\(a(2) = a(1) - 5 = -2 - 5 = -7\)[/tex] (using the recursive formula)

3. [tex]\(a(3) = a(2) - 5 = -7 - 5 = -12\)[/tex] (using the recursive formula)

4. [tex]\(a(4) = a(3) - 5 = -12 - 5 = -17\)[/tex] (using the recursive formula)

The recursive formula tells us how to calculate each term in the sequence based on the previous term. Starting with \(a(1)\), we use the formula to find [tex]\(a(2)\)[/tex], then use [tex]\(a(2)\) to find \(a(3)\)[/tex], and so on.

So, the 4th term [tex](\(a(4)\))[/tex] is found by taking the previous term [tex](\(a(3)\))[/tex], which is -12, and subtracting 5.

Complete the question:

a(1) = -2;

Find the 4th term in the sequence.

Final answer:

The 4th term in the sequence defined by a(1) = -2 and a(n) = a(n − 1) − 5 is -17, which is found by successively subtracting 5 from the previous term.

Explanation:

To find the 4th term in a sequence where a(1) = -2 and a(n) = a(n − 1) − 5, we will use the recurrence relation to determine each subsequent term:

Therefore, the 4th term in the sequence is -17.

Answer:

1/12

1/2 x 1/6 = 1/12

half of the numbers are even and 1/6 o the numbers is 3.

Step-by-step explanation:

The probability of rolling an even number and then a 3 is,

⇒ 1 / 12

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Now, the probability of rolling an even number on the first roll.

Then, There are three even numbers 2, 4, and 6 out of the 6 possible outcomes,

so the probability of rolling an even number on the first roll is,

= 3/6,

= 1/2

And, For the probability of rolling a 3 on the second roll.

There is only one outcome that will result in a 3 out of the six possible outcomes,

so the probability of rolling a 3 on the second roll is 1/6.

Now we can multiply the two probabilities together to find the probability of rolling an even number on the first roll and then a 3 on the second roll:

1/2 x 1/6 = 1/12

Hence, the probability of rolling an even number and then a 3 is,

⇒ 1 / 12

Answer:

If you meant [80 + (8*4) ]/2,  then  [80 + (8*4) ]/2=56

or if you meant 80 +  [ 8*4 /  2], then 80 +  [ 8*4 /  2] = 96

Step-by-step explanation:

Evalute the expression. 80 + (8x4) divided by 2

so do you mean

the whole expression 80 + (8x4)   is  over  2 ?

If so then:

evaluate  8x4  =  8 * 4 = 32.

so   we have 80 + (8x4)   is  over  2  =  (80 + 32)/2 = 112/2 = 56

If you meant  80 +  [ 8*4 /  2]

then  80 +  [ 8*4 /  2] = 80 + 8*2 = 80 + 16 = 96
