Coincident lines are lines that are the same.

In the beginning of both equations we have '4x' and '8x'.

Note that 8 / 4 = 2.

Multiply the rest of the numbers in the first equation by 2.

5y * 2 = 10y

8 * 2 = 16

So our 2nd line will be:

8x + 10y = 16

Your friend has recently learned about coprime numbers. A pair of numbers {a, b} is called coprime if the maximum number that di

s344n2d4d5 [400]

Answer:

(5, 7, 15)

Step-by-step explanation:

A pair of numbers is coprime if the maximum number that divides the two is 1.

Consider the three numbers: 5, 7, 15

The first two numbers 5 and 7 can only be divided by 1. Hence the pair (5, 7) is coprime.

The second pair of numbers 7 and 15 is also coprime as the number which can divide both these numbers is 1. So the pair (7, 15) is also coprime

So, we have two pairs of coprime numbers: (5,7) and (7,15)

According to the friend, (5, 15) must also be coprime, but this not true as both these numbers can also be divided by 5.

Hence, the three numbers meeting the said criterion are: (5, 7, 15)

Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace t

KengaRu [80]

Answer:

0.139

Step-by-step explanation:

We are given that

Total number of cards=52

n=18

We have to find the probability of drawing at least 7 spades

Total number of spaded in deck of 52 cards=13

Probability of getting spade= $p=\frac{13}{52}=\frac{1}{4}$

Probability, $P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}$

Probability of getting no spade= $q=1-p=1-\frac{1}{4}=\frac{3}{4}$

By binomial theorem of probability

$P(X=x)=\binom{n}r}p^rq^{n-r}$

P(x $\geq 7)=1-P(x\leq 6)$

The probability of drawing at least 7 spades= $1-\sum_{r=0}^{6}\binom{18}{r}(\frac{3}{4})^{18-r}(\frac{1}{4})^r$

The probability of drawing at least 7 spades=0.139

In a cinema, there are eight seats in a row. Four of the seats in one row are occupied. What fraction of seats are available in

Anarel [89]

Answer:

<h2> $\frac{1}{2}$ </h2>

Step-by-step explanation:

Given,

There are 8 seats in a row.

There are 8 seats in a row.4 seats are occupied.

Available seats = 8 - 4 = 4 seats

Fraction of seats available:

$\frac{number \: of \: seats \: available}{total \: number \: of \: seats}$

$= \frac{4}{8}$

Reduce the fraction with GCF 4

$= \frac{1}{2}$

Hope this helps..

Best regards!!
