I Nee Answer Immediately!!!!!!!!

Answer:

The answer is "A mean of 0 and a standard deviation of 1".

Step-by-step explanation:

The standard answer of its following formula is calculated by:

[tex]\to z=\frac{X-\mu}{\sigma}[/tex]

Its standard score relates to the sampling distribution with the normal distribution average standard variation of 0 and 1, correspondingly. The mean for a standard scoring is 0, and the normal deviation is 1. that's why the mean=0, standard deviation=1.

Answer:

16

Step-by-step explanation:

Number of boys who played cricket=12

ie, it is the 3 times of boys who played tennis

then,

Number of boys who played tennis =12÷3 =4

therefore,

Total number of boys=Number of boys who played cricket +Number of boys who played tennis

=12+4=16

Answer:

sample

or spot check

Step-by-step explanation:

there are quite a number of different terms that can be used depending on the specific scientific field you are working in.

but "sample" should be the most common one for a random selection of a subset of the whole set.

Answer:

$10,400

Step-by-step explanation:

2 ft

Step-by-step explanation:

The height from which the beach ball was thrown happens when t = 0. So setting t = 0 to get y, we get

y = [-16(0) - 2](0 - 1)

= (-2)(-1)

= 2 ft

Therefore, the ball was thrown from a height of 2 ft.

Answer:

118419,54

Step-by-step explanation:

Primero, convierta R como porcentaje en r como decimal

r = R / 100

r = 16/100

r = tasa de 0,16 por año,

Luego resuelve la ecuación para A

A = P (1 + r / n) ^ nt

A = Cantidad =?

P = Principal = 80000

R = 16%

n = Compuesto trimestralmente = 4

t = tiempo en años

= 2 años y 6 meses

12 meses = 1 año

6 meses = x

x = 6/12 = 0,5

t = 2.5 años

A = 80000,00 (1 + 0,16 / 4) (4) ^ (2,5)

A = 80000,00 (1 + 0,04)^ (10)

A = $ 118419,54

To do the following I first listed the numbers from least to greatest

mean: (also known as average) is 7 just add all the numbers together and divide by the amount of numbers there are which is 77/11

median: 5 it's the middle number (5, 5, 6)

mode: 2 the number that appears the most

range: 16 difference between the highest value and the lowest (18-2)

quartile 1: 2 median of the lower half

quartile 3: 9 median of the upper half

interquartile range: 7 (Q3-Q1)

hope this helped :)

Probability that both Rebecka and Aaron select poodles is  4/81

It is a branch of mathematics that deals with the occurrence of a random event.

Given,

A pet store has 9 puppies.

includes 2 poodles, 5 terriers, and 2 retrievers.

Rebecka selects one puppy at random.

The probability of selection one pet from store is 1/9

After Rebecka selects one puppy at random pet store replaces the puppy with a puppy of the same breede. Now store has same number of pets.

Aaron chooses a puppy at random.

The probability of Aaron selecting a pet is 1/9.

As they both selects a poodle,

Rebecka : Probability of selection one poodle from store is 2/9

Aaron: Probability of selection one poodle from store is 2/9

The probability that both Rebecka and Aaron select poodles is 2/9 × 2/9 = 4/81

Hence probability that both Rebecka and Aaron select poodles is  4/81

D) Identifies the transaction and is located at the top right corner of the check

Step-by-step explanation:

The check number on a check is the number located at the top right corner of the check, and it can also be found at the bottom of the check, located in lower right corner after the routing number and the account number

The check number aids in the tracking and identifying bank transactions such as to identify checks that the bank has processed and to know outstanding checks that are yet to be processed.

The check number also aids in balancing of the checkbook.

Therefore, the check number on a check identifies the transactions and is located at the top right corner of the check.

The required value of the given expression is 6x3 - 13x2 - 13x + 20. Option B is correct.

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the monomial, binomial and trinomial, etc. ax+b is a polynomial.

here,
= (3x² + x - 4)(2x - 5)
= [6x³-13x² - 13z + 20]

Thus, the required value of the given expression is 6x3 - 13x2 - 13x + 20. Option B is correct.

1. 3x(6x + 13) + 5(6x + 13)

2. 18x2 + 39x + 5(6x + 13)

3. 18x2 + 39x + 30 + 65

4. 18x2 + 69 + 65

The inequality equation is x ≥ ( by - c - d ) / a

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

by - d ≤ ax + c    be equation (1)

On simplifying the equation , we get

Subtracting c on both sides of the equation , we get

by - d - c ≤ ax

And , ax ≥ by - d - c

Divide by a on both sides of the equation , we get

x ≥ ( by - c - d ) / 2

Hence , the inequality is x ≥ ( by - c - d ) / a
