<h2>Answer:</h2>

The probability of first picking a dime and then, without replacing it, selecting a nickel is:

                           \dfrac{1}{10}

<h2>Step-by-step explanation:</h2>

It is given that:

Dianna has 4 quarters, 3 dimes, and 3 nickels in her purse.

This means that there are a total of: 4+3+3=10 coins

Now, the probability of first picking a dime is: 3/10

and then we will be left with : 9 coins

The probability of selecting a nickel in second choice is: 3/9=1/3

Hence, the total probability is:

\dfrac{3}{10}\times \dfrac{1}{3}=\dfrac{1}{10}

<span> At the beginning there are 3 dimes out of 10 coins:
P(first coin is a dime) = 3/10

After that there are 3 nickels out of 9 remaining coins:
P(second coin is a nickel) = 3/9 = 1/3

P(dime, then nickel) = P(first coin is a dime) x P(second coin is a nickel)
= 3/10 x 1/3
= 1/10

Answer:
1/10  . if im wrong im sorry </span>

-6x + 3 ≥ 21

Subtract 3 from both sides.

-6x ≥ 21 - 3

Simplify.

-6x ≥ 18

Divide both sides by -6.

Remember, when dividing or multiplying by a negative number, you must switch the signs.

x ≤ 18 / -6

Simplify.

x ≤ -3

So, your answer is D)  x ≤ -3

~Hope I helped!~

X2-7x-18÷x2+8x+12 what is it in lowest terms
Eddi Din [679]

\dfrac{x^2-7x-18}{x^2+8x+12}=\dfrac{x^2+2x-9x-18}{x^2+6x+2x+12}=\dfrac{x(x+2)-9(x+2)}{x(x+6)+2(x+6)}\\\\=\dfrac{(x+2)(x-9)}{(x+6)(x+2)}=\dfrac{x-9}{x+6}

If |AB| / |DE|=7/5 then what is |AD| / |CD|?DE is parallel to AB
Dmitriy789 [7]

Answer: AD/CD = 2/5

Explanation:

Triangle ABC is similar to triangle DEC on the basis of AA(Angle angle)

Recall, if 2 triangles are similar, it means that the ratio of their corresponding sides are equal. Thus,

AB/DE = BC/EC = AC/DC

From the information given,

AB/DE = 7/5

Thus,

AC/DC = 7/5

AD + CD = AC

(AD + CD)/DC = 7/5

AD/DC + CD/DC = 7/5

AD/DC + 1 = 7/5

AD/DC = 7/5 - 1

AD/DC = 2/5

AD/CD = 2/5
