Hey there!

“Simplify (1 + 3)2 – 10 = 2”

IN ORDER FOR YOU TO SOLVE FOR THIS EQUATION YOU HAVE TO DO PEMDAS

- (P)arentheses

- (E)xponents

- (M)ultiplication

- (D)ivsion

- (A)ddition

- (S)ubtraction

(1 + 3)2 – 10 = 2

(1 + 3) = 4

4(2) – 10

4(2) = 8

8 – 10 = –2

Answer: –2 ≠ 2 so this makes this statement FALSE

Good luck on your assignment and enjoy your day!

Suppose that two cards are randomly selected from a standard 52-card deck. (a) What is the probability that the first card is a

Roman55 [17]

Answer:

a. $\frac{1}{17}$

b. $\frac{1}{16}$

Step-by-step explanation:

We are given that two cards are drawn are randomly selected from a standard 52- cards deck.

Total cards=52

Total number of spade cards=13

Probability= $\frac{number\;of\;favourable\;cases}{total\;number\;of cases}$

a.The probability of drawing two cards first card is spade and second card is spade without replacement = $\frac{13}{52}\times \frac{12}{51}$

The probability of drawing two cards first card is spade and second card is spade= $\frac{1}{17}$

b. The probability of drawing two cards first is spade and second card is a spade with replacement = $\frac{13}{52}\times\frac{13}{52}$

The probability of drawing two cards first is spade and second card is a spade with replacement = $\frac{1}{16}$

What is the partial product for 652 x 4= 2,608

Law Incorporation [45]

To find out the answer of the two multiplied products with the help of partial products we separate into unit based numbers so as to, for easier calculation and simplification with units of zeroes. So, in this case we are given the product of 4 times of 652.

Here we need to expand this product of higher number to zeroes and take aside the added numbers to come back to the original multiple of a product. That is:

$\huge{652}$

$\begin{bmatrix}652 \\ + \\ 0 \end{bmatrix}$

We just separated and expanded the product to be multiplied by removing other units following it. Same goes for other units at Hundredth, tenth and unitary position.

Therefore,

$\begin{bmatrix}600 \\ + \\ 52 \end{bmatrix}$

For tenth term.

$\begin{bmatrix}50 \\ + \\ 2 \end{bmatrix}$

The terms after splitting and expanding the product before multiplication is:

$\begin{bmatrix}600 \\ 50 \\ 2 \end{bmatrix}$

Multiply the product elements in individual manner and add the elements forged by individual multiplication to get the required solution.

$\therefore \quad \begin{bmatrix}600 \times 4 \\ 50 \times 4 \\ 2 \times 4 \end{bmatrix}$

$\begin{bmatrix}600 \times 4 \\ + \\ 200 \\ + \\ 2 \times 8 \end{bmatrix}$

$\begin{bmatrix}2400 \\ + \\ 200 \\ + \\ 2 \times 8 \end{bmatrix}$

$\begin{bmatrix}2600 \\ + \\ 8 \end{bmatrix}$

$\boxed{\mathbf{Final \: \: Answer \: = \: 2,608}}$

Hope it helps.

1. There are 50 contestants signed up for a TV show. There are 36 more female contestants than male contestants. How many female

Novosadov [1.4K]

The number of female contestants who signed up to compete is; 43.

<h3>What is the number of female contestants?</h3>

Let number of females = x

Let number of males = y.

Hence, it follows from the task content that;

x+y = 50

x-y = 36.

Hence, by adding both equations together in a bid to determine the number of females; we have;

2x = 86

x = 43.
