what is 5x8=40 in division

Answer:

(a) D. All the above

(b) [tex]p = 10[/tex] --- Mean

(c) [tex]s = 3[/tex] --- Standard Deviation

(d) A. No, 15 is not a significantly high number of golf balls, because the probability of 15 is greater than 0.05

Step-by-step explanation:

Solving (a):

Option (d) answers the question because (a), (b) and (c) are all true

For (a): x must be a random variable

For (b): [tex]\sum p(x) = 1[/tex]

For (c): [tex]0 \le p(x) \le 1[/tex]

Solving (b): The mean

Mean (p) is calculated as:

[tex]p = \sum xp(x)[/tex]

So, we have:

[tex]p = 3 * 0.14 + 6 * 0.03 + 9 * 0.36 + 12 * 0.37 + 15 * 0.10[/tex]

[tex]p = 9.78[/tex]

[tex]p = 10[/tex]

Solving (c): The standard deviation

This is calculated as:

[tex]s = \sqrt{\sum[ x*p(x) *(1-p(x))]}[/tex]

So, we have:

[tex]s = \sqrt{3 * 0.14 *(1 - 0.14) + 6 * 0.03 * (1 - 0.03) +..............+ 15 * 0.10 * (1 - 0.10)}[/tex][tex]s = \sqrt{6.7566}[/tex]

[tex]s = 2.599[/tex]

[tex]s = 3[/tex]

Solving (d): Is P(x = 15) significantly high?

From the question:

[tex]P(x = 15) = 0.10[/tex]

In probability:

[tex]0 \le x \le 0.15[/tex] is considered to be low (i.e. not high) because it is almost not sure to occur

Hence, (a) is true

Answer:

the answer is the last one

Answer:

21.29 units

Step-by-step explanation:

30° 60° 90° triangles have a specific side ratio.

With respect to side a, x is side a, x√3 is side b, and 2x is side c.

Therefore the perimeter is the sum of these sides.

c is the long side so:

9 = 2x. x = 9/2 = 4.5.

x√3 = 4.5√3 ≈ 4.5 × 1.73 ≈ 7.79.

Perimeter = x + x√3 + 2x =

(9/2) + (9/2)√3 + 9 = 4.5 + 7.79 + 9 = 21.29.

From the central limit theorem, the interval can the researcher be 95% certain that the sample mean will fall within A. $257.82 and $272.18.

How to use the Central limit theorem?

We are given;

Population Mean; μ = $265

Population standard deviation; σ = $40.93

Sample size; n = 130

The central limit theorem (CLT) postulates that the distribution of sample mean approximates a normal distribution with larger sample sizes, disregarding the population's distribution.

This implies that sample sizes equal to or greater than 30 are often considered sufficient for the Central limit theorem to hold.

Thus, by the central limit theorem, the interval can the researcher be 95% certain that the sample mean will fall within A. $257.82 and $272.18.

Answer:

11

Step-by-step explanation:

A prime number is a number that cannot be factored other than 1 and that number is self thus, 11 will be the prime number.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

A prime number is a number that cannot be factored other than 1 and that number is self.

For example, 9 can be written as 3 x 3 thus it will not prime number and 11 cannot be written as two products other than 1 x 11 thus it will be a prime number.

Hence "A prime number is a number that cannot be factored other than 1 and that number is self thus, 11 will be the prime number".

Answer:1310

Step-by-step explanation:

Answer:

0.079

Step-by-step explanation:

Number of suit of hearts = 13

Total number of cards in deck = 52

P(drawing a suit of heart) = number of suit of heart / total number of cards in deck

P(drawing a suit of heart) = 13 /52 = 1 /4

Hence, Probability of success, p = 1/4

P(not drawing a suit of heart) = 1 - 1/4 = 3/4

Hence, Probability of performing exactly 5 draws :

To perform exactly 5 draws :

1st draw = not a heart suit

2nd draw = not a heart suit

3rd draw = not a heart suit

4th draw = not a heart suit

5 draw = a heart suit

P(performing exactly 5 draws) =

(3/4 * 3/4 * 3/4 * 3/4 * 1/4)

= 0.0791015625

= 0.079

Answer:

x=4

Step-by-step explanation:

The left and right sides are equal so:

5x-2 + 4x = 7x-4 + x+6

Collect the like terms and calculate the sum :

9x-2 = 8x+2

Move terms and change it's sign:

9x-8x = 2+2

And finally:

x=4

Also if you solve the equations of the other sides you'll find x₁=0.5 and x₂=4

which the intersection with the previous answer will be x=4
