Answer:

a) 3/100

Step-by-step explanation:

There are 25 total chips

P(Yellow) = 3/25

With no replacement P(Blue) = 6/24 = 1/4

Multiply 3/25* 1/4= 3/100

Solve for the unknown side in the right triangle if b=24 and c=26 find a
cluponka [151]

Answer:

Option C

Step-by-step explanation:

Use the <u>Pythagorean Theorem</u> to find the unknown side.

a^2+b^2=c^2

<h3>We are given that:</h3>
  • b=24
  • c=26

We need to solve for a.

a^2+24^2=26^2\\\\ \text {Solve Exponents:}\\\rightarrow 24^2 = 576\\\rightarrow 26^2 = 676\\\\a^2+576=676\\\rightarrow a^2+576-576=676-576 \text{ (Subtraction Property of Equality)}\\a^2=100\\\sqrt{a^2} =\sqrt{100} \text { (Take the square root on both sides.) }\\\\\boxed {a=100}

<em>Option C should be the correct answer.</em>

Find the value of x for which the lines r and s are parallel. answers: 13 47 48 12
juin [17]

Answer:

x=12

Step-by-step explanation:

142 and 3x+2 are supplementary angles when the lines are parallel

142+ 3x+2 = 180

Combine like terms

144+3x= 180

Subtract 144 from each side

144+3x-144=180-144

3x=36

Divide by 3

3x/3 = 36/3

x =12

Find the sum of this arithmetic series.<br> | 26 + 24.5 + 23 + 21.5 + ... - 17.5
emmainna [20.7K]

Answer:

127.5

Step-by-step explanation:

The given series is 26 + 24.5 + 23 + 21.5 + ... - 17.5

The first term of this series is a=26

The common difference is d=24.5-26=-1.5

The last term of the series is -17.5

The nth term is given by:

u_n=a+d(n-1)

26+-1.5(n-1)=-17.5

-1.5n=-17.5-26-1.5

-1.5n=-45

n=30

The sum of the series:

S_{n}=\frac{n}{2}(a+l)

S_{30}=\frac{30}{2}(26+-17.5)

S_{30}=127.5
